I was always just thinking this process
[TS]
00:00:01
◼
►
that would save me I just thought like
[TS]
00:00:03
◼
►
well I'll just I'll stick it out and
[TS]
00:00:05
◼
►
nobody knew file system here probably
[TS]
00:00:07
◼
►
next year and I've been thinking that
[TS]
00:00:08
◼
►
for a lot of years
[TS]
00:00:10
◼
►
well I spent this morning trying to
[TS]
00:00:13
◼
►
parallel eyes the lame mp3 encoder why
[TS]
00:00:16
◼
►
why not very hard problem that hasn't
[TS]
00:00:20
◼
►
been solved since like the early two
[TS]
00:00:21
◼
►
thousands and I often need to encode our
[TS]
00:00:26
◼
►
show mp3 which takes probably i don't
[TS]
00:00:29
◼
►
know 90 seconds to include it's it's
[TS]
00:00:31
◼
►
it's a surprisingly long time for a
[TS]
00:00:34
◼
►
modern computing tasks like that and
[TS]
00:00:36
◼
►
that annoys me and so I figured why
[TS]
00:00:38
◼
►
don't I spend the afternoon seeing if I
[TS]
00:00:40
◼
►
can paralyze the the mp3 encoder and I
[TS]
00:00:43
◼
►
have to enter there are faster encoders
[TS]
00:00:46
◼
►
than the lame encoder and I know this is
[TS]
00:00:49
◼
►
hard for me to talk about being know
[TS]
00:00:50
◼
►
that the word lame is really not a nice
[TS]
00:00:54
◼
►
word to say but it's kind of like the
[TS]
00:00:56
◼
►
like the gift photo editor like also not
[TS]
00:00:59
◼
►
a nice word to say and for whatever
[TS]
00:01:01
◼
►
reason these open source project named
[TS]
00:01:02
◼
►
themselves these acronyms without regard
[TS]
00:01:04
◼
►
to what those words mean and how they
[TS]
00:01:06
◼
►
hurt people so i'm sorry in advance but
[TS]
00:01:08
◼
►
it's called the lame mp3 encoder it and
[TS]
00:01:11
◼
►
it is I i have tested many different
[TS]
00:01:14
◼
►
encoding options for podcast audio from
[TS]
00:01:16
◼
►
mp3 AAC the HEA see like the the mp3
[TS]
00:01:20
◼
►
protocol like that the add-on like
[TS]
00:01:22
◼
►
spectral record things to these formats
[TS]
00:01:25
◼
►
and simple joint stereo with the lame
[TS]
00:01:28
◼
►
mp3 encoder is by far the the highest
[TS]
00:01:30
◼
►
quality and at the best bit rates that I
[TS]
00:01:32
◼
►
have been found
[TS]
00:01:33
◼
►
it's really it's really quite good so
[TS]
00:01:35
◼
►
problem is mp3 encoding is very
[TS]
00:01:38
◼
►
difficult to parallel eyes at least
[TS]
00:01:41
◼
►
while also doing it well and so that's
[TS]
00:01:43
◼
►
what I'm kind of trying to do here just
[TS]
00:01:45
◼
►
for ATP well I mean ideally I would you
[TS]
00:01:48
◼
►
know ship this to other people as well
[TS]
00:01:50
◼
►
you know maybe open source it or maybe
[TS]
00:01:51
◼
►
just embedded into my production tool
[TS]
00:01:54
◼
►
about that I have to at some point
[TS]
00:01:55
◼
►
hopefully maybe release so that it could
[TS]
00:01:58
◼
►
it could be helpful because one of the
[TS]
00:02:00
◼
►
problems is like we've basically hit a
[TS]
00:02:01
◼
►
wall of single-threaded performance on
[TS]
00:02:04
◼
►
modern computers like we're not really
[TS]
00:02:06
◼
►
getting much better at that and that
[TS]
00:02:08
◼
►
that's like one of the only tasks that i
[TS]
00:02:09
◼
►
do a regular basis my computer where I'm
[TS]
00:02:11
◼
►
just like dying for more
[TS]
00:02:13
◼
►
4 gigahertz on my own one core so if i
[TS]
00:02:17
◼
►
can eliminate that that that makes me
[TS]
00:02:18
◼
►
happy with my computers and it makes me
[TS]
00:02:20
◼
►
happier with you know potential future
[TS]
00:02:22
◼
►
imax and mac pros and macbooks and
[TS]
00:02:25
◼
►
things because I can include our show
[TS]
00:02:26
◼
►
you for eight times faster and fast
[TS]
00:02:29
◼
►
enough that doesn't matter anymore
[TS]
00:02:32
◼
►
that makes sense well good luck i mean
[TS]
00:02:35
◼
►
i'd love to see that happen because i
[TS]
00:02:37
◼
►
think would make a lot of people very
[TS]
00:02:38
◼
►
happy but got that sounds like a royal
[TS]
00:02:40
◼
►
pain in the hindquarters it really is
[TS]
00:02:42
◼
►
the the one saving grace of this is that
[TS]
00:02:45
◼
►
that you know normally if you're dealing
[TS]
00:02:47
◼
►
with like a non-trivial sized open
[TS]
00:02:50
◼
►
source project or heck even regular
[TS]
00:02:52
◼
►
sized one usually they have HS
[TS]
00:02:54
◼
►
dependency hell and usually it is so
[TS]
00:02:56
◼
►
hard to get to the point where you can
[TS]
00:02:58
◼
►
even build the thing let alone like
[TS]
00:03:00
◼
►
trying to make changes and you know try
[TS]
00:03:03
◼
►
to test things and it it is such a pain
[TS]
00:03:06
◼
►
because they all depend on with your
[TS]
00:03:07
◼
►
weird crazy libraries that you don't
[TS]
00:03:09
◼
►
have that yet that are hard to install
[TS]
00:03:11
◼
►
mac OS 10 or something and it's such a
[TS]
00:03:13
◼
►
pain usually lame is actually really
[TS]
00:03:16
◼
►
simple there's not much to it it's it's
[TS]
00:03:19
◼
►
not very many files and there's as far
[TS]
00:03:22
◼
►
as I know there's no external
[TS]
00:03:24
◼
►
dependencies and except maybe like you
[TS]
00:03:26
◼
►
know basically be stuff that everything
[TS]
00:03:27
◼
►
has so it's pretty it's really actually
[TS]
00:03:30
◼
►
quite pleasant to work on so kudos to
[TS]
00:03:34
◼
►
the lane project this all see your C++
[TS]
00:03:36
◼
►
it's all see which is also nice guy i
[TS]
00:03:38
◼
►
don't really know a lot of c++ so it has
[TS]
00:03:41
◼
►
a movie piercy is is also kind of a
[TS]
00:03:43
◼
►
welcome welcome change
[TS]
00:03:46
◼
►
it's like back a few jobs ago back when
[TS]
00:03:48
◼
►

[TS]
00:03:50
◼
►
still like see a lot I mean I recognize
[TS]
00:03:53
◼
►
that you know it you know it like
[TS]
00:03:55
◼
►
working and see nowadays it's like
[TS]
00:03:57
◼
►
having like a like a classic car that
[TS]
00:03:59
◼
►
you work on your garage you know it's
[TS]
00:04:01
◼
►
like it's like it's really it's really
[TS]
00:04:03
◼
►
fulfilling and its really nice and cool
[TS]
00:04:06
◼
►
did if if that's like your personality
[TS]
00:04:07
◼
►
type but i really would would be
[TS]
00:04:10
◼
►
hard-pressed to justify using it for
[TS]
00:04:12
◼
►
like quote real work anymore but but I
[TS]
00:04:15
◼
►
really do enjoy working with it now in
[TS]
00:04:18
◼
►
the on you know on the occasion that i
[TS]
00:04:20
◼
►
need to work on it or not I mean
[TS]
00:04:23
◼
►
anything's better than perl PHP am i
[TS]
00:04:25
◼
►
so anyway we should do some fun
[TS]
00:04:26
◼
►
well this year mac pro support this is
[TS]
00:04:30
◼
►
not good times for John siracusa that's
[TS]
00:04:33
◼
►
not so bad times either marcos theory
[TS]
00:04:35
◼
►
was that it was because of the
[TS]
00:04:36
◼
►
instructions
[TS]
00:04:37
◼
►
yeah my theory was the heart hardware
[TS]
00:04:39
◼
►
like encryption instructions that intel
[TS]
00:04:42
◼
►
has added over time but turns out
[TS]
00:04:43
◼
►
nope well I mean we didn't get any
[TS]
00:04:45
◼
►
official word on it but talking to a
[TS]
00:04:47
◼
►
whole bunch of people hey why do you
[TS]
00:04:48
◼
►
think they dropped support for this
[TS]
00:04:49
◼
►
computer that computer the general
[TS]
00:04:51
◼
►
consensus was that they just dropped
[TS]
00:04:53
◼
►
support for computers that are old
[TS]
00:04:55
◼
►
because it's a pain in the butt to keep
[TS]
00:04:56
◼
►
supporting them and there's lots of
[TS]
00:04:57
◼
►
things that are a pain to keep
[TS]
00:04:58
◼
►
supporting and if you do anything to us
[TS]
00:05:02
◼
►
that changes sort of the driver model or
[TS]
00:05:03
◼
►
the requires drivers to be even just
[TS]
00:05:06
◼
►
recompiled or change in some subtle way
[TS]
00:05:08
◼
►
supporting old hardware like say the
[TS]
00:05:11
◼
►
airport card that could be put into my
[TS]
00:05:13
◼
►
2008 mac pro that's kind of a pain and
[TS]
00:05:16
◼
►
you don't want to bother with that but
[TS]
00:05:17
◼
►
the big one I think is a video drivers
[TS]
00:05:19
◼
►
because there's usually some
[TS]
00:05:21
◼
►
participation from the video card vendor
[TS]
00:05:23
◼
►
whether it be a AMD ati or nvidia in the
[TS]
00:05:27
◼
►
creation of the drivers for OS 10 for
[TS]
00:05:30
◼
►
these various GPUs and apple doesn't
[TS]
00:05:32
◼
►
wanna keep doing that and usually if you
[TS]
00:05:34
◼
►
were to go to AMD and say hey we're
[TS]
00:05:36
◼
►
making a new version of the operating
[TS]
00:05:38
◼
►
system can you help us or either help us
[TS]
00:05:41
◼
►
to or do entirely on your own drivers
[TS]
00:05:43
◼
►
for that work with the Sierra colonel
[TS]
00:05:47
◼
►
and this ancient 2008 mac pro I don't
[TS]
00:05:50
◼
►
think they're came to do that but anyway
[TS]
00:05:52
◼
►
lots of reasons why you might want to
[TS]
00:05:54
◼
►
support old hardware and yeah no no
[TS]
00:05:58
◼
►
specific smoking gun for any particular
[TS]
00:06:00
◼
►
hardware feature that is not supported
[TS]
00:06:03
◼
►
and adding adding to this pile of a
[TS]
00:06:05
◼
►
support for the idea that it's just
[TS]
00:06:07
◼
►
because it's old is that 2009 macros are
[TS]
00:06:10
◼
►
also not supported the contrary drove i
[TS]
00:06:12
◼
►
hoped on the last show
[TS]
00:06:14
◼
►
so that means my work Mac can't run
[TS]
00:06:15
◼
►
Sierra either we're gonna do I'm gonna
[TS]
00:06:19
◼
►
wait i'm going to wait until the new
[TS]
00:06:20
◼
►
it's almost it's almost this you have to
[TS]
00:06:22
◼
►
buy a new computer
[TS]
00:06:23
◼
►
I everyone gets laptops at work now so
[TS]
00:06:25
◼
►
i'm going to wait until the new macbook
[TS]
00:06:26
◼
►
pros come out and then i'm going to wait
[TS]
00:06:29
◼
►
another month and then I'm going to get
[TS]
00:06:32
◼
►
a new computer work now you you do
[TS]
00:06:34
◼
►
realize that the new macbook pros will
[TS]
00:06:36
◼
►
almost certainly have the arrow key
[TS]
00:06:38
◼
►
layout that you hate
[TS]
00:06:39
◼
►
I'm not gonna use that keyboard yeah
[TS]
00:06:42
◼
►
that's it it's just gonna be sitting off
[TS]
00:06:44
◼
►
to the side with a screen that I never
[TS]
00:06:46
◼
►
look at connected to an external screen
[TS]
00:06:48
◼
►
like i'm just using it as a weird-shaped
[TS]
00:06:50
◼
►
mac mini that's my plan because i only
[TS]
00:06:53
◼
►
have one screen at work and it's not a
[TS]
00:06:55
◼
►
great screen but whatever it's fine
[TS]
00:06:57
◼
►
so I'll keep doing that are probably
[TS]
00:06:58
◼
►
want to get the 15-inch so i can put in
[TS]
00:06:59
◼
►
mirrored display mode but that's how
[TS]
00:07:02
◼
►
much i'm not going to use a second
[TS]
00:07:03
◼
►
screen just so my windows and crap won't
[TS]
00:07:05
◼
►
move when i disconnect the monitor
[TS]
00:07:06
◼
►
availability the same as on both you
[TS]
00:07:08
◼
►
know I mean that's my current plan i
[TS]
00:07:11
◼
►
love that your current plan like I
[TS]
00:07:13
◼
►
clearly didn't even consider another mac
[TS]
00:07:15
◼
►
pro well I cannot work would never buy
[TS]
00:07:19
◼
►
that for me like I my back was the first
[TS]
00:07:21
◼
►
mac at the entire company and I had to
[TS]
00:07:23
◼
►
get special dispensation to get it and
[TS]
00:07:25
◼
►
it was like way more expensive than the
[TS]
00:07:27
◼
►
four hundred dollar piece of crap dell
[TS]
00:07:28
◼
►
laptops they were getting everybody back
[TS]
00:07:30
◼
►
mine was like the cheapest possible mac
[TS]
00:07:32
◼
►
pro you could get in the minimum
[TS]
00:07:34
◼
►
configuration it was like fifteen
[TS]
00:07:35
◼
►
hundred dollars and it took so much for
[TS]
00:07:38
◼
►
them to choke it down
[TS]
00:07:39
◼
►
nowadays they're better about buying max
[TS]
00:07:42
◼
►
if you want and they'll buy you know
[TS]
00:07:43
◼
►
their danger 15-inch macbook pro and
[TS]
00:07:46
◼
►
that's what I plan on getting but not
[TS]
00:07:48
◼
►
the mac pro is not an option either is
[TS]
00:07:51
◼
►
an imac for that matter would you get an
[TS]
00:07:53
◼
►
imac over a macbook pro if you had the
[TS]
00:07:55
◼
►
yes I would is the is the base model 5k
[TS]
00:07:58
◼
►
imac not price competitive with the
[TS]
00:08:00
◼
►
15-inch macbook pro I don't think its
[TS]
00:08:03
◼
►
price i think it's in understand big
[TS]
00:08:06
◼
►
corporations they just want to do things
[TS]
00:08:07
◼
►
the way they want to do them and they
[TS]
00:08:09
◼
►
want regularity and uniformity they
[TS]
00:08:11
◼
►
don't want you to be a special snowflake
[TS]
00:08:12
◼
►
on specific computer they only having
[TS]
00:08:15
◼
►
support and know and understand two
[TS]
00:08:17
◼
►
kinds of computers on the backside and
[TS]
00:08:20
◼
►
whatever I don't maybe i'll ask about it
[TS]
00:08:23
◼
►

[TS]
00:08:25
◼
►
my company is get least Max and I think
[TS]
00:08:29
◼
►
there are two year leases and basically
[TS]
00:08:31
◼
►
your choices are macbook pro if you do
[TS]
00:08:33
◼
►
some sort of development work i believe
[TS]
00:08:35
◼
►
a macbook air if you don't or some sort
[TS]
00:08:38
◼

tuesday that on WABC was going on there
[TS]
00:12:59
◼
►
was a talk show again this year was it
[TS]
00:13:01
◼
►
two years ago that we were guess I think
[TS]
00:13:04
◼
►
and then you know the only the only
[TS]
00:13:05
◼
►
reasonable conclusion after having a
[TS]
00:13:07
◼
►
listen this impossibly awesome an
[TS]
00:13:09
◼
►
attractive trio on stage
[TS]
00:13:12
◼
►
is to have a filler who followed up last
[TS]
00:13:16
◼
►
year and then this year what are you
[TS]
00:13:18
◼
►
gonna do well why not have Phil Schiller
[TS]
00:13:20
◼
►
and Craig federighi and we were all
[TS]
00:13:24
◼
►
there we were sitting in the front row
[TS]
00:13:26
◼
►
and it was amazing and i cannot say
[TS]
00:13:30
◼
►
enough good things about this this talk
[TS]
00:13:32
◼
►
show if you are not a regular talks or
[TS]
00:13:33
◼
►
listener if you're one of the ten people
[TS]
00:13:35
◼
►
that do not listen to the talk show but
[TS]
00:13:36
◼
►
do listen to the show I cannot encourage
[TS]
00:13:40
◼
►
you enough to listen to this episode of
[TS]
00:13:42
◼
►
the talk show will have a link in the
[TS]
00:13:43
◼
►
show notes it is excellent there's also
[TS]
00:13:44
◼
►
a video I which was very good from what
[TS]
00:13:47
◼
►
I've gathered i haven't actually watched
[TS]
00:13:48
◼
►
it myself but seeing Craig and Phil talk
[TS]
00:13:53
◼
►
to each other and talk to the audience
[TS]
00:13:56
◼
►
and talk to John Gruber all of all the
[TS]
00:13:58
◼
►
above was amazing and there's a few line
[TS]
00:14:01
◼
►
items that we'd like to go through about
[TS]
00:14:03
◼
►
that but one of the things that made me
[TS]
00:14:05
◼
►
kind of laugh and and really that I
[TS]
00:14:08
◼
►
loved about it made me love Craig better
[TS]
00:14:10
◼
►
even more was as the talk show is going
[TS]
00:14:15
◼
►
Craig on the surface looked comfortable
[TS]
00:14:18
◼
►
but if you really looked at him for more
[TS]
00:14:19
◼
►
than a second you realize he is not in
[TS]
00:14:22
◼
►
love with what he's doing right now not
[TS]
00:14:24
◼
►
like not the john was doing anything
[TS]
00:14:25
◼
►
wrong not that phil was doing anything
[TS]
00:14:27
◼
►
wrong you can just tell the Craig was
[TS]
00:14:29
◼
►
like a little nervous and not entirely
[TS]
00:14:31
◼
►
comfortable with what was going on and
[TS]
00:14:33
◼
►
he was leaning forward a lot he he kept
[TS]
00:14:36
◼
►
tonight i did the same thing when we
[TS]
00:14:37
◼
►
were on the talk show at that dub he
[TS]
00:14:40
◼
►
kept leaning forward and then like
[TS]
00:14:42
◼
►
putting his his elbow on his knee and in
[TS]
00:14:44
◼
►
propping his head up and then I think
[TS]
00:14:46
◼
►
you could really realize that kinda
[TS]
00:14:48
◼
►
looks a little weird for those in the
[TS]
00:14:50
◼
►
audience then he would try to like
[TS]
00:14:51
◼
►
casually put his arm down which I'm sure
[TS]
00:14:53
◼
►
if we look at the video of me onstage I
[TS]
00:14:55
◼
►
probably this 35 times but there's
[TS]
00:14:57
◼
►
there's a lot of that but the thing that
[TS]
00:14:59
◼
►
struck me the most was when John Gruber
[TS]
00:15:05
◼
►
talked about something developer related
[TS]
00:15:08
◼
►
not only did Craig have impossibly good
[TS]
00:15:12
◼
►
answers for all the questions sometimes
[TS]
00:15:14
◼
►
more forthcoming then maybe he should
[TS]
00:15:16
◼
►
have but he SAT bolt upright every time
[TS]
00:15:20
◼
►
and he was so confident and so sure of
[TS]
00:15:23
◼
►
himself and it was so awesome
[TS]
00:15:25
◼
►
to see and god I love that guy so much
[TS]
00:15:28
◼
►
yeah it was such a good show
[TS]
00:15:30
◼
►
I mean it really was you know you can
[TS]
00:15:32
◼
►
you can think about like you know what
[TS]
00:15:34
◼
►
what kind of show would you expect to
[TS]
00:15:36
◼
►
have where Apple executives give an
[TS]
00:15:39
◼
►
interview you know and and if you think
[TS]
00:15:41
◼
►
about it just like that you might think
[TS]
00:15:43
◼
►
well they shouldn't be you know going
[TS]
00:15:45
◼
►
over PR talking points and everything
[TS]
00:15:46
◼
►
and certainly some of what they say is
[TS]
00:15:49
◼
►
PR talking points but it most of it
[TS]
00:15:51
◼
►
isn't and most of it is like yeah and I
[TS]
00:15:55
◼
►
won't talk to this weekend without yet
[TS]
00:15:57
◼
►
but I basically reviewed the show for
[TS]
00:16:00
◼
►
John on his own chosen no he wouldn't do
[TS]
00:16:02
◼
►
it himself and so forget the repetition
[TS]
00:16:05
◼
►
here but i think one of the best insight
[TS]
00:16:09
◼
►
about the first of all is that we got to
[TS]
00:16:11
◼
►
see to apple executives interacting with
[TS]
00:16:13
◼
►
each other and you never see that like
[TS]
00:16:16
◼
►
even people in apple hardly ever see
[TS]
00:16:18
◼
►
that it's okay to see that in this
[TS]
00:16:22
◼
►
contact these these two people who
[TS]
00:16:24
◼
►
clearly have known each other for a very
[TS]
00:16:25
◼
►
long time and working for a very long
[TS]
00:16:27
◼
►
time to people on top of their game and
[TS]
00:16:30
◼
►
phil and Craig are really excellent at
[TS]
00:16:33
◼
►
their jobs and they both have incredibly
[TS]
00:16:37
◼
►
deep knowledge about the stuff that we
[TS]
00:16:39
◼
►
care about and the stuff that grouper
[TS]
00:16:41
◼
►
would be asking questions about activity
[TS]
00:16:43
◼
►
c so like I was thinking like you know
[TS]
00:16:45
◼
►
we were speculating beforehand know
[TS]
00:16:47
◼
►
who's gonna have this you have this year
[TS]
00:16:48
◼
►
and you know one of the one of the ideas
[TS]
00:16:51
◼
►
what if he asked him cook and having Tim
[TS]
00:16:54
◼
►
Cook would be like it'd be really like a
[TS]
00:16:56
◼
►
great badge of honor it would be like a
[TS]
00:16:58
◼
►
really noteworthy thing but I think
[TS]
00:17:00
◼
►
having filling Craig is actually a
[TS]
00:17:02
◼
►
better set for that audience for that
[TS]
00:17:05
◼
►
time because phil is really lit in many
[TS]
00:17:09
◼
►
ways it seems like he is kind of like
[TS]
00:17:12
◼
►
the head of product direction on some
[TS]
00:17:14
◼
►
level and and you know it seems to be
[TS]
00:17:16
◼
►
kind of a shared role in Steve's absence
[TS]
00:17:18
◼
►
you know Johnny obviously has something
[TS]
00:17:20
◼
►
to do with it
[TS]
00:17:21
◼
►
I think Tim still has some probably
[TS]
00:17:22
◼
►
something to do with it as well and who
[TS]
00:17:24
◼
►
knows who else but it seems like a lot
[TS]
00:17:26
◼
►
of that falls on Phil just display
[TS]
00:17:28
◼
►
products students in general also phil
[TS]
00:17:30
◼
►
is the head of the app store now
[TS]
00:17:31
◼
►
so again like very relevant to this
[TS]
00:17:34
◼
►
audience and then you have a federal key
[TS]
00:17:39
◼
►
you know yes we knew he was the
[TS]
00:17:40
◼
►
executive in charge of software
[TS]
00:17:42
◼
►
engineering stuff but i don't think a
[TS]
00:17:45
◼
►
lot of us knew quite how much of an
[TS]
00:17:46
◼
►
engineer he is and also you know not
[TS]
00:17:49
◼
►
only does he have deep technical chops
[TS]
00:17:51
◼
►
but he also has deep knowledge of like
[TS]
00:17:55
◼
►
specific implementation details of the
[TS]
00:17:57
◼
►
stuff they're doing now so it's not like
[TS]
00:17:59
◼
►
he ascended into the into like this
[TS]
00:18:00
◼
►
ivory tower and is just like dictating
[TS]
00:18:03
◼
►
things down to his minutes have them do
[TS]
00:18:04
◼
►
all the work and he's just being a
[TS]
00:18:05
◼
►
figurehead he's clearly still very much
[TS]
00:18:07
◼
►
involved in those decisions and very
[TS]
00:18:11
◼
►
like very very very technical down too
[TS]
00:18:13
◼
►
deep levels and and able to explain that
[TS]
00:18:16
◼
►
very well
[TS]
00:18:17
◼
►
so to have that combo of like the
[TS]
00:18:21
◼
►
product guy in the app store guy and you
[TS]
00:18:23
◼
►
know infill and then to have Craig as
[TS]
00:18:25
◼
►
like the technical head is is really i
[TS]
00:18:29
◼
►
think the perfect combo to have at WC +
[TS]
00:18:32
◼
►
i think their personalities work really
[TS]
00:18:33
◼
►
well both in general and also with John
[TS]
00:18:36
◼
►
Gruber being the interviewer so overall
[TS]
00:18:39
◼
►
I I i would much rather have them then
[TS]
00:18:42
◼
►
have Tim in that context and I think it
[TS]
00:18:45
◼
►
was as good as it possibly can i think
[TS]
00:18:46
◼
►
it was great
[TS]
00:18:47
◼
►
mostly agree with other team would have
[TS]
00:18:49
◼
►
been more boring but I've been thinking
[TS]
00:18:50
◼
►
about it more since the DC we could like
[TS]
00:18:52
◼
►
it really does depend on the topic that
[TS]
00:18:54
◼
►
you're interested in you know if it
[TS]
00:18:56
◼
►
mentioned Johnny I've obviously if
[TS]
00:18:58
◼
►
you're going to have a bunch of
[TS]
00:18:59
◼
►
questions about design stuff he's the
[TS]
00:19:02
◼
►
guy you want and Phil is not going to be
[TS]
00:19:04
◼
►
able to give you much they're neither is
[TS]
00:19:05
◼
►
Craig for that matter because like you
[TS]
00:19:07
◼
►
know product design whether it be
[TS]
00:19:08
◼
►
hardware or software is Johnny's domain
[TS]
00:19:10
◼
►
and a lot of the decisions that are made
[TS]
00:19:11
◼
►
they're at their you know i would
[TS]
00:19:13
◼
►
imagine that they could add some inside
[TS]
00:19:15
◼
►
of you need you want the man himself if
[TS]
00:19:16
◼
►
you wanna get that information so
[TS]
00:19:17
◼
►
there's Johnny set aside and then Tim
[TS]
00:19:19
◼
►
after Apple comes out with the car the
[TS]
00:19:21
◼
►
guy you want to talk to him cook until
[TS]
00:19:24
◼
►
you know like the deep car people
[TS]
00:19:25
◼
►
because your main question is why is
[TS]
00:19:26
◼
►
Apple chosen to make a car and the
[TS]
00:19:28
◼
►
person who can answer that best is tim
[TS]
00:19:29
◼
►
cook right because that's a decision at
[TS]
00:19:32
◼
►
his level so I would actually like to
[TS]
00:19:34
◼
►
see tim cook at some point but for the
[TS]
00:19:36
◼
►
topics i was interested in this year and
[TS]
00:19:38
◼
►
most years
[TS]
00:19:38
◼
►
yeah I'd rather hear from craig and to a
[TS]
00:19:41
◼
►
lesser extent filled because I'm much
[TS]
00:19:43
◼
►
more interested in the technical less
[TS]
00:19:44
◼
►
interested in the app store stuff but
[TS]
00:19:45
◼
►
the WC like you said a lot of people
[TS]
00:19:48
◼
►
interested in appstore exactly the
[TS]
00:19:50
◼
►
reason the talk show
[TS]
00:19:51
◼
►
live is a topic in the follow-up ears
[TS]
00:19:54
◼
►
because i was adding items to follow up
[TS]
00:19:55
◼
►
of bits and pieces and I realized most
[TS]
00:19:56
◼
►
of them were information from the talk
[TS]
00:19:59
◼
►
show live
[TS]
00:19:59
◼
►
the main reason i was just people listen
[TS]
00:20:01
◼
►
to it is that it has information that
[TS]
00:20:04
◼
►
you probably won't see elsewhere because
[TS]
00:20:06
◼
►
you know i can fill and Craig around
[TS]
00:20:08
◼
►
there and they didn't just say things
[TS]
00:20:10
◼
►
that were already said that WC they
[TS]
00:20:13
◼
►
didn't just say things that have already
[TS]
00:20:14
◼
►
been said by Apple PR they provided new
[TS]
00:20:16
◼
►
information and some but i thought was
[TS]
00:20:18
◼
►
interesting and and you won't know
[TS]
00:20:19
◼
►
unless you listen to that or listen to
[TS]
00:20:22
◼
►
these tidbits that I pulled out of it
[TS]
00:20:24
◼
►
the first one is about an iOS 10 how you
[TS]
00:20:27
◼
►
can get rid of the Apple apps like if
[TS]
00:20:29
◼
►
you don't the stock app so that the tips
[TS]
00:20:31
◼
►
app or whatever you don't have to hide
[TS]
00:20:33
◼
►
them in a folder anymore you can now
[TS]
00:20:34
◼
►
delete them but they aren't actually
[TS]
00:20:37
◼
►
deleted as many people speculated and
[TS]
00:20:39
◼
►
has been speculated for a long time
[TS]
00:20:40
◼
►
before the future even appeared they're
[TS]
00:20:42
◼
►
not actually removed from the system
[TS]
00:20:43
◼
►
even though when you delete them you can
[TS]
00:20:45
◼
►
go to the store and then redownload them
[TS]
00:20:47
◼
►
but as I think it was Craig said on
[TS]
00:20:48
◼
►
stage that download will run
[TS]
00:20:50
◼
►
suspiciously fast because i am actually
[TS]
00:20:52
◼
►
from your computer all the apps are
[TS]
00:20:55
◼
►
saying oh yeah I'll redownload those for
[TS]
00:20:56
◼
►
you and it just reveals them again a
[TS]
00:20:58
◼
►
bunch of reasons were given for actually
[TS]
00:21:00
◼
►
leaving them on the system you will
[TS]
00:21:02
◼
►
delete I think the documents and data
[TS]
00:21:03
◼
►
associated with it but you won't do the
[TS]
00:21:04
◼
►
actual executable so that was
[TS]
00:21:07
◼
►
interesting tidbit the other one is
[TS]
00:21:09
◼
►
relevant to a couple of stories and
[TS]
00:21:11
◼
►
tweets that are going around about the
[TS]
00:21:12
◼
►
the current beta of the appstore add
[TS]
00:21:14
◼
►
service where they'll you know people
[TS]
00:21:16
◼
►
can try it out for free now and all you
[TS]
00:21:19
◼
►
do at this point is say yes I want to
[TS]
00:21:20
◼
►
help my app into the ad service
[TS]
00:21:22
◼
►
I don't think either the keywords and
[TS]
00:21:24
◼
►
everything as well but anyway I looked
[TS]
00:21:25
◼
►
around and couldn't find anything else
[TS]
00:21:27
◼
►
to do so I have to my at my appt in but
[TS]
00:21:30
◼
►
I think that just means that apple will
[TS]
00:21:31
◼
►
I can shove it on top of search results
[TS]
00:21:33
◼
►
sometimes but I don't think I have any
[TS]
00:21:35
◼
►
control over that
[TS]
00:21:37
◼
►
yeah it's like the automated woman is
[TS]
00:21:38
◼
►
that if you don't want to pick your
[TS]
00:21:39
◼
►
keywords in doing that stuff just we'll
[TS]
00:21:41
◼
►
figure it out for you and so one of the
[TS]
00:21:42
◼
►
little controversies that spun up on
[TS]
00:21:45
◼
►
Twitter was a i think it was someone
[TS]
00:21:47
◼
►
from Tweetbot was saying they search for
[TS]
00:21:49
◼
►
tweet pot like the actual name of the
[TS]
00:21:51
◼
►
application and the number-one hit the
[TS]
00:21:53
◼
►
ad at the top of the other search
[TS]
00:21:54
◼
►
results wasn't ad for twitterrific and
[TS]
00:21:58
◼
►
it looks like all twitterrific has
[TS]
00:21:59
◼
►
purchased the tweet but keyword but they
[TS]
00:22:01
◼
►
haven't because you can't even do that
[TS]
00:22:03
◼
►
at that point and I didn't
[TS]
00:22:04
◼
►
and that brings up the whole topic that
[TS]
00:22:06
◼
►
we discussed before about buying someone
[TS]
00:22:09
◼
►
else's trademark as a keyword so if you
[TS]
00:22:11
◼
►
have an application if you were you know
[TS]
00:22:13
◼
►
the the maker of Twitter everything you
[TS]
00:22:15
◼
►
wanted to buy the word the keyword
[TS]
00:22:17
◼
►
Tweetbot could you do that that was
[TS]
00:22:19
◼
►
addressed by Phil Schiller and the
[TS]
00:22:21
◼
►
doctor alive and he said that they are
[TS]
00:22:25
◼
►
explicitly allowing this i think this is
[TS]
00:22:27
◼
►
a direct quote from the transmittances
[TS]
00:22:28
◼
►
you can use someone else's brand in your
[TS]
00:22:30
◼
►
AdWords that you want as we thought
[TS]
00:22:33
◼
►
about it that is more likely to benefit
[TS]
00:22:34
◼
►
the small developer than the big
[TS]
00:22:36
◼
►
developer the idea is that if you have a
[TS]
00:22:39
◼
►
well-known brand if you like clash of
[TS]
00:22:40
◼
►
clans or something you're not going to
[TS]
00:22:43
◼
►
by keyword for some tiny little
[TS]
00:22:45
◼
►
application doesn't time a little
[TS]
00:22:46
◼
►
similar game that doesn't sell a lot of
[TS]
00:22:48
◼
►
copies but if you make a game it's
[TS]
00:22:49
◼
►
similar to clash of clans and you want
[TS]
00:22:51
◼
►
to break into the market and really
[TS]
00:22:53
◼
►
right now you don't have any customers
[TS]
00:22:54
◼
►
maybe you by the clash of clans keyword
[TS]
00:22:56
◼
►
that is the theory behind this and Phil
[TS]
00:22:58
◼
►
articulates it is the most
[TS]
00:23:01
◼
►
straightforward manner is you're going
[TS]
00:23:02
◼
►
to get and it was surprising to a lot of
[TS]
00:23:04
◼
►
people and we'll see how it plays out
[TS]
00:23:05
◼
►
real life but from the perspective of
[TS]
00:23:08
◼
►
app developers especially after the
[TS]
00:23:10
◼
►
operation of on are uneven footing it
[TS]
00:23:12
◼
►
seems like a pretty scummy thing to do
[TS]
00:23:14
◼
►
to buy your competitors trademark so i
[TS]
00:23:17
◼
►
think a lot of people are not going to
[TS]
00:23:18
◼
►
do it because it seems rude and I would
[TS]
00:23:20
◼
►
imagine the companies that would do it
[TS]
00:23:22
◼
►
are exactly the companies that are big
[TS]
00:23:24
◼
►
because they have no scruples and aren't
[TS]
00:23:26
◼
►
run by an individual who is answerable
[TS]
00:23:27
◼
►
to their practices and they have a
[TS]
00:23:29
◼
►
marketing department is measured on how
[TS]
00:23:31
◼
►
well they boost sales and so i think is
[TS]
00:23:33
◼
►
gonna happen a lot
[TS]
00:23:34
◼
►
I'm not entirely convinced that it's
[TS]
00:23:36
◼
►
going to benefit the small developer
[TS]
00:23:37
◼
►
more than the big developer but we'll
[TS]
00:23:39
◼
►
see and again we'll talk directly about
[TS]
00:23:41
◼
►
this issue when questioned about it on
[TS]
00:23:43
◼
►
dr. live so check it out
[TS]
00:23:44
◼
►
yeah i think it there's a number of you
[TS]
00:23:47
◼
►
know issues and factors that go into
[TS]
00:23:49
◼
►
what exactly is a small developer
[TS]
00:23:50
◼
►
because I think who this will actually
[TS]
00:23:53
◼
►
hurt most are people like twitterrific
[TS]
00:23:56
◼
►
and Tweetbot and maybe overcast we're
[TS]
00:24:00
◼
►
kind of medium-sized developers were
[TS]
00:24:02
◼
►
like we're not big enough for like the
[TS]
00:24:04
◼
►
clash of clans people to build our
[TS]
00:24:05
◼
►
keywords because who cares like you know
[TS]
00:24:07
◼
►
we are nothing compared to what they get
[TS]
00:24:09
◼
►
and we're also not related but other
[TS]
00:24:12
◼
►
people who makes you know who make apps
[TS]
00:24:14
◼
►
are related to podcasting or related to
[TS]
00:24:17
◼
►
Twitter
[TS]
00:24:18
◼
►
would very easily like bid on like the
[TS]
00:24:20
◼
►
medium-sized apps in their category and
[TS]
00:24:22
◼
►
on those keywords so like you know I
[TS]
00:24:24
◼
►
view myself as a small developer in the
[TS]
00:24:26
◼
►
grand scheme of things but a lot of
[TS]
00:24:29
◼
►
people view / cast as a big gap in the
[TS]
00:24:31
◼
►
category relative to their app so like
[TS]
00:24:34
◼
►
you know I think when Phil says this he
[TS]
00:24:36
◼
►
thinks this will benefit small
[TS]
00:24:37
◼
►
developers I don't think he's talking
[TS]
00:24:39
◼
►
about people like overcast and Tweetbot
[TS]
00:24:41
◼
►
and twitterrific i think is talking
[TS]
00:24:43
◼
►
about like little things that most of us
[TS]
00:24:45
◼
►
have never heard of that happen to be in
[TS]
00:24:47
◼
►
the same categories
[TS]
00:24:48
◼
►
he's right that it would probably
[TS]
00:24:49
◼
►
benefit them like you know the kind of
[TS]
00:24:52
◼
►
thing where like if you search for that
[TS]
00:24:54
◼
►
Twitter or whatever you know you get a
[TS]
00:24:56
◼
►
couple of twitter apps and you get a
[TS]
00:24:57
◼
►
whole bunch of what looks like just
[TS]
00:24:59
◼
►
garbage and spam and it's like you know
[TS]
00:25:00
◼
►
photo rotation apps for twitter or stuff
[TS]
00:25:03
◼
►
like that you know that kind of stuff
[TS]
00:25:04
◼
►
it's gonna be that kind of app I think
[TS]
00:25:08
◼
►
that bet that could benefit from this
[TS]
00:25:09
◼
►
not medium-sized apps like to directly
[TS]
00:25:12
◼
►
pot overcast
[TS]
00:25:14
◼
►
the other problem here is well and if
[TS]
00:25:17
◼
►
that happens to the project one is that
[TS]
00:25:19
◼
►
we've had you know kind of a kind of
[TS]
00:25:22
◼
►
like down low key word spam issues in
[TS]
00:25:25
◼
►
iTunes Connect since the beginning the
[TS]
00:25:26
◼
►
app store you know the apps have a
[TS]
00:25:28
◼
►
keyword field they can enter keywords
[TS]
00:25:30
◼
►
into it for search and those have
[TS]
00:25:32
◼
►
historically been used pretty pretty
[TS]
00:25:34
◼
►
strongly for relevance in search more so
[TS]
00:25:37
◼
►
than the description that is publicly
[TS]
00:25:38
◼
►
shown the problem is these keywords are
[TS]
00:25:41
◼
►
not publicly visible anywhere and so
[TS]
00:25:43
◼
►
there's kind of no downside for a nap to
[TS]
00:25:46
◼
►
put its competitors or other large apps
[TS]
00:25:49
◼
►
names in those keywords and Apple has a
[TS]
00:25:51
◼
►
rule against this but in practice that
[TS]
00:25:54
◼
►
rules only really enforced and
[TS]
00:25:55
◼
►
enforceable against like large trademark
[TS]
00:25:59
◼
►
like Disney you know so if you it'd be
[TS]
00:26:01
◼
►
hard to put disney in your keywords and
[TS]
00:26:02
◼
►
get accepted your app review but you
[TS]
00:26:05
◼
►
know if if another twitter app puts
[TS]
00:26:07
◼
►
Tweetbot it's keywords that is way more
[TS]
00:26:10
◼
►
likely to get in and to get to get
[TS]
00:26:12
◼
►
through and historically that has been
[TS]
00:26:14
◼
►
seemingly very badly enforced by app
[TS]
00:26:16
◼
►
review and Phil even kind of said
[TS]
00:26:18
◼
►
something along the lines of like we
[TS]
00:26:20
◼
►
know we're going to be you know trying

something to that degree and then
[TS]
00:26:25

thirdly the problem is the name of you

notice if you put down

overcast your
[TS]

word and use might search for the word
[TS]
00:26:33

overcast to test this out and then my
[TS]
00:26:36
◼

app shows up below some added you might
[TS]
00:26:38

think this is horrible
[TS]
00:26:39

my app is not called overcast in the app
[TS]

store my app is called overcast colon
[TS]

podcast player and if you look at almost

every other instance of this of this
[TS]
00:26:49
◼

kind of like you know add doing what
[TS]
00:26:50

seems like the wrong thing like Tweetbot
[TS]
00:26:53
◼

is not just named Tweetbot twitterrific
[TS]
00:26:55
◼

is not just named twitterrific so it's

called like you know tweetbot for

twitter twitter fake twitter client
[TS]
00:27:00

stuff like that like we missed you know
[TS]
00:27:02
◼

in the last couple years that we've all
[TS]
00:27:05
◼

kind of succumb to having to add
[TS]
00:27:07
◼
►
keywords to our apt names because quite
[TS]
00:27:10
◼
►
simply it works better and the search
[TS]
00:27:12
◼

has been horrible and it's been one of
[TS]
00:27:13
◼

the only ways you your gave up on the
[TS]
00:27:16
◼

search improving like you know what
[TS]
00:27:17
◼
►
forget we will mango we will mangle the
[TS]
00:27:19
◼

name of our application because there's
[TS]
00:27:21
◼
►
no other way to come up in the search
[TS]
00:27:23
◼
►
results i mean i remember when traffic
[TS]
00:27:24
◼
►
today years ago like it was a sad day
[TS]
00:27:26
◼
►
because it just really ugly ass up the
[TS]
00:27:27
◼
►
name but the problem is people would
[TS]
00:27:29
◼
►
search for twitter and just the
[TS]
00:27:30
◼
►
twitterrific would be 700 results down
[TS]
00:27:33
◼
►
like the relevance was so bad even
[TS]
00:27:35
◼
►
though it was a popular third-party
[TS]
00:27:36
◼
►
twitter client and when someone searches
[TS]
00:27:38
◼
►
for Twitter it would be a good idea to
[TS]
00:27:39
◼
►
show them the you know we'll reviewed
[TS]
00:27:43
◼
►
popular frequently updated Twitter
[TS]
00:27:45
◼
►
clients and instead it's like no Twitter
[TS]
00:27:47
◼
►
doesn't appear anywhere in your name or
[TS]
00:27:48
◼
►
does but it's just a prefix and like the
[TS]
00:27:51
◼
►
fact that twitterrific didn't show up in
[TS]
00:27:53
◼
►
the search results for Twitter into
[TS]
00:27:54
◼
►
waited lowdown that's just said so i
[TS]
00:27:56
◼
►
would hope that as part of this effort
[TS]
00:27:57
◼
►
to like police the keywords for
[TS]
00:27:59
◼
►
trademarks more often and stuff they
[TS]
00:28:01
◼
►
will also improve the search of the
[TS]
00:28:02
◼
►
point where you don't have to name angle
[TS]
00:28:04
◼
►
essentially anymore but we'll see
[TS]
00:28:06
◼
►
well the other thing is like I try with
[TS]
00:28:08
◼
►
overcast I tried not name mangling but
[TS]
00:28:10
◼
►
you know i launched overcast fairly late
[TS]
00:28:12
◼
►
in the appstore relative to the other
[TS]
00:28:13
◼
►
apps there was already an app named
[TS]
00:28:16
◼
►
exactly the string overcast
[TS]
00:28:18
◼
►
in fact even kind of the developer and
[TS]
00:28:19
◼
►
tried to buy it from him and he agreed
[TS]
00:28:21
◼
►
and we had agreed to actually transfer
[TS]
00:28:23
◼
►
this app to me just so I could like
[TS]
00:28:24
◼
►
delete it and reuse the name but the app
[TS]
00:28:27
◼
►
use iCloud and so we couldn't transfer
[TS]
00:28:30
◼
►
what why don't you just the one it just
[TS]
00:28:32
◼
►
came to rename it i think i somehow we
[TS]
00:28:34
◼
►
just like I just kind of like we can
[TS]
00:28:36
◼
►
drop the ball on continuing the
[TS]
00:28:37
◼
►
conversation so I admire it probably
[TS]
00:28:38
◼
►
just fell apart
[TS]
00:28:40
◼
►
just through apathy but like there is an
[TS]
00:28:42
◼
►
app called overcast it's it's a i
[TS]
00:28:44
◼
►
believe the seller's name is Willis
[TS]
00:28:46
◼
►
ingersoll something that it's like a
[TS]
00:28:47
◼
►
file transfer app for cloud services and
[TS]
00:28:50
◼
►
the app store like even though the world
[TS]
00:28:52
◼
►
of trademark allows for the same name to
[TS]
00:28:55
◼
►
be used in different industries in
[TS]
00:28:57
◼
►
different contexts the app store doesn't
[TS]
00:29:00
◼
►
unless you do weird tricks with
[TS]
00:29:01
◼
►
international titles so it sometimes
[TS]
00:29:03
◼
►
does but usually doesn't it's like it's
[TS]
00:29:06
◼
►
it's that section that's so this is like
[TS]
00:29:10
◼
►
you know the combination of lots of
[TS]
00:29:12
◼
►
long-standing appstore problems results
[TS]
00:29:15
◼
►
in this like mediocre situation we have
[TS]
00:29:17
◼
►
with titles with keywords after them
[TS]
00:29:19
◼
►
along with you know the new ads not
[TS]
00:29:22
◼
►
matching things exactly probably yeah
[TS]
00:29:24
◼
►
it's gonna be interesting
[TS]
00:29:26
◼
►
uh let's talk about Apple photos and the
[TS]
00:29:30
◼
►
john sarkissian controller search
[TS]
00:29:33
◼
►
yeah that was our my quality metric I
[TS]
00:29:36
◼
►
call the original problem that I have is
[TS]
00:29:38
◼
►
that i couldn't find a picture of my
[TS]
00:29:39
◼
►
playstation 4 controller in Apple's
[TS]
00:29:41
◼
►
photos application this is before iOS 10
[TS]
00:29:44
◼
►
before WTC so I put all my photos into
[TS]
00:29:45
◼
►
google photos and amazingly UFOs was
[TS]
00:29:47
◼
►
able to find it just made me typing the
[TS]
00:29:49
◼
►
word controller and of course Apple
[TS]
00:29:51
◼
►
announced similar foto search for iOS 10
[TS]
00:29:55
◼
►
and mac OS Sierra and I speculated on
[TS]
00:29:59
◼
►
last show that it would not be able to
[TS]
00:30:02
◼
►
find controller by me typing controller
[TS]
00:30:04
◼
►
because Apple is not good at the type of
[TS]
00:30:06
◼
►
thing and Google is so now having
[TS]
00:30:08
◼
►
installed a actually i haven't installed
[TS]
00:30:12
◼
►
and many other people have installed i
[TS]
00:30:13
◼
►
have installed Michael CRP i have
[TS]
00:30:15
◼
►
installed iOS 10 many other people have
[TS]
00:30:16
◼
►
installed all these betas onto their
[TS]
00:30:19
◼
►
iphones because they're very brave
[TS]
00:30:20
◼
►
people and they have taken my exact
[TS]
00:30:22
◼
►
pictures of the controller they pull
[TS]
00:30:24
◼
►
them from Twitter and put them into
[TS]
00:30:25
◼
►
their photo libraries and down the
[TS]
00:30:26
◼
►
search receive would find it and it
[TS]
00:30:28
◼
►
doesn't find if you type controller but
[TS]
00:30:30
◼
►
because Apple search APIs foto search
[TS]
00:30:32
◼
►
works a little bit differently or at
[TS]
00:30:33
◼
►
least present a different UI then Google
[TS]
00:30:35
◼
►
fotosearch it does find it when you type
[TS]
00:30:38
◼
►
control stick or I think also gamepad
[TS]
00:30:40
◼
►
and this brings up the the the UI that
[TS]
00:30:44
◼
►
arises as you type it shows like
[TS]
00:30:45
◼
►
category results as if it puts things
[TS]
00:30:49
◼
►
into buckets and indeed it does kan has
[TS]
00:30:51
◼
►
a blog post
[TS]
00:30:52
◼
►
that list out all of the buckets that it
[TS]
00:30:55
◼
►
has something like 4,000 buckets to put
[TS]
00:30:58
◼
►
things in there's a lot of stuff in
[TS]
00:31:00
◼
►
their dance palaces banana chairlifts
[TS]
00:31:05
◼
►
wait what's a dance palace is seriously
[TS]
00:31:07
◼
►
i don't know i'm just reading some of
[TS]
00:31:08
◼
►
the keywords here or kid kiln got killed
[TS]
00:31:12
◼
►
that's a good one
[TS]
00:31:12
◼
►
polos blocks pulley trikes trumpets to
[TS]
00:31:16
◼
►
but bass horn
[TS]
00:31:17
◼
►
I mean like it's got huge amount of
[TS]
00:31:19
◼
►
things basically if you type a word that
[TS]
00:31:21
◼
►
is not one of the words on this list it
[TS]
00:31:23
◼
►
won't find it so as you type it's
[TS]
00:31:24
◼
►
showing you the words that begin with
[TS]
00:31:25
◼
►
their contain these things so it's a
[TS]
00:31:27
◼
►
little bit different you I was trying to
[TS]
00:31:29
◼
►
lead you to its notion of those things
[TS]
00:31:31
◼
►
so if you type control start typing
[TS]
00:31:33
◼
►
controller and you see control stick
[TS]
00:31:34
◼
►
you probably tap that one so good job
[TS]
00:31:39
◼
►
APPL photos so far on finding the
[TS]
00:31:42
◼
►
controller that I didn't think you would
[TS]
00:31:43
◼
►
ever find because that's that's good
[TS]
00:31:45
◼
►
photo recognition because the controller
[TS]
00:31:46
◼
►
was upside down any searches pretty
[TS]
00:31:48
◼
►
obscure category on the other hand
[TS]
00:31:50
◼
►
someone also said that Apple's
[TS]
00:31:52
◼
►
fotosearch thinks because it couldn't
[TS]
00:31:53
◼
►
find birthday pics or babies or pictures
[TS]
00:31:56
◼
►
of a couch so I don't know if they think
[TS]
00:31:58
◼
►
just had an indexed everything yet or
[TS]
00:32:00
◼
►
those things aren't among keywords or
[TS]
00:32:01
◼
►
anything like that but we'll see as this
[TS]
00:32:03
◼
►
rules out but you can finally your dance
[TS]
00:32:05
◼
►
palaces if you have pictures of dance
[TS]
00:32:06
◼
►
palaces it will find that before it will
[TS]
00:32:08
◼
►
find your couch not quite sure what
[TS]
00:32:10
◼
►
would come up for dance palace but yeah
[TS]
00:32:11
◼
►
I'm you know I have my entire photo
[TS]
00:32:13

library in google photos and also my
[TS]
00:32:15
◼
►
entire photo library and apples photos
[TS]
00:32:17
◼
►
so when these things release for real i
[TS]
00:32:19
◼
►
can do a B test right next to each other
[TS]
00:32:20
◼
►
with the exact same library and do a
[TS]
00:32:23
◼
►
little break off and when that happens i
[TS]
00:32:24
◼
►
will definitely have some results but so
[TS]
00:32:28
◼
►
far so good for Apple it is more
[TS]
00:32:29
◼

impressive than I thought it would be

brand-new which was the last time it was

update over the LED display that came

the Thunderbolt Display has been

in the box and write something like that

very pretty too to see what's on the
[TS]
00:35:07
◼
►
screen as well however does this make us
[TS]
00:35:09
◼
►
think that maybe a retina displays
[TS]
00:35:12
◼
►
coming soon maybe with the GPU built-in
[TS]
00:35:15
◼
►
I don't know I i would think so but it
[TS]
00:35:17
◼
►
seems odd to me that they would just
[TS]
00:35:19
◼
►
continue
[TS]
00:35:19
◼
►
without having something to replace it
[TS]
00:35:21
◼
►
and maybe they just don't sell enough of
[TS]
00:35:23
◼
►
them maybe they can't get that screen
[TS]
00:35:25
◼
►
from the vendor anymore because it's so
[TS]
00:35:26
◼
►
terrible because the pixels of the size
[TS]
00:35:27
◼
►
of bullets i don't know like the apples
[TS]
00:35:30
◼
►
did you read apples official statement
[TS]
00:35:31
◼
►
that promotes yeah i was really short
[TS]
00:35:34
◼
►
wasn't we're gonna go we're just
[TS]
00:35:36
◼
►
continuing the apple thunderbolt display
[TS]
00:35:37
◼
►
will be available through apple.com
[TS]
00:35:38
◼
►
apple retail stores not authorized
[TS]
00:35:40
◼
►
resellers while supplies last
[TS]
00:35:42
◼
►
there are a number of great third-party
[TS]
00:35:44
◼
►
options available for Mac users it's
[TS]
00:35:46
◼
►
kind of surprising that they even gave a
[TS]
00:35:49
◼
►
statement about it like that they that
[TS]
00:35:50
◼
►
they call the attention to it at all I
[TS]
00:35:52
◼
►
mean usually when Apple discontinues a
[TS]
00:35:54
◼
►
product like you know it's like when
[TS]
00:35:55
◼
►
it's not very important that you just
[TS]
00:35:57
◼
►
kind of quietly removed from sale like
[TS]
00:35:59
◼
►
it's I think it's usually a clear
[TS]
00:36:01
◼
►
replacement when they do that that's
[TS]
00:36:02
◼
►
like they remove the old one and as
[TS]
00:36:03
◼
►
always the new one and this is a little
[TS]
00:36:05
◼
►
bit weird but they're removing the old
[TS]
00:36:06
◼
►
one without anyone to replace it and I
[TS]
00:36:09
◼
►
still put the odds that greater than
[TS]
00:36:11
◼
►
50-percent that there will be
[TS]
00:36:12
◼
►
replacement for this product
[TS]
00:36:14
◼
►
oh yeah because it's such a gimme they
[TS]
00:36:15
◼
►
have the screen it's in the five um I
[TS]
00:36:17
◼
►
quit staring at it for a long time you
[TS]
00:36:19
◼
►
put in a case you know just ship it like
[TS]
00:36:21
◼
►
but maybe that's not ready yet and maybe
[TS]
00:36:23
◼
►
it's part of the harbor announcement for
[TS]
00:36:24
◼
►
whatever reason that it's like I I think
[TS]
00:36:27
◼
►
I don't think that's a lot of wonderful
[TS]
00:36:29
◼
►
display so thousand-dollar monitor that
[TS]
00:36:31
◼
►
is not worth a thousand dollars at this
[TS]
00:36:33
◼
►
point like arguable you could argue
[TS]
00:36:34
◼
►
about it when i was first introduced but
[TS]
00:36:36
◼
►
it is a really nice monitor and back
[TS]
00:36:37
◼
►
before they were there were no options
[TS]
00:36:39
◼
►
for 27 dresses when it was introduced in
[TS]
00:36:41
◼
►
2011 so it was good weather was four
[TS]
00:36:43
◼
►
thousand dollars who knows but at this
[TS]
00:36:45
◼
►
point it's definitely not worth thousand
[TS]
00:36:46
◼
►
dollar so they must not have been
[TS]
00:36:47
◼
►
selling a lot of them and as they know
[TS]
00:36:50
◼
►
you know while supplies last they need
[TS]
00:36:51
◼
►
to get rid of all his inventory maybe it
[TS]
00:36:53
◼
►
takes this long to get rid of the
[TS]
00:36:55
◼
►
inventory at the rate that they sell
[TS]
00:36:56
◼
►
like maybe they have a lot of wonderful
[TS]
00:36:58
◼
►
displays hanging around and they did the
[TS]
00:36:59
◼
►
math and said if we want these flushed
[TS]
00:37:02
◼
►
out of the inventory about time we
[TS]
00:37:03
◼
►
introduce the 5k external display we
[TS]
00:37:04
◼
►
need to just continue it now and just
[TS]
00:37:06
◼
►
let them sell out the rest of them it
[TS]
00:37:08
◼
►
would also help by the way Apple if you
[TS]
00:37:09
◼
►
lower the price because that's a way
[TS]
00:37:10
◼
►
that you can sell things faster break
[TS]
00:37:12
◼
►
i mean i-i think it's more likely that
[TS]
00:37:14
◼
►
like you know that the rumors were all
[TS]
00:37:17
◼
►
really clear and the timing makes a lot
[TS]
00:37:19
◼
►
of sense that like the the new skylight
[TS]
00:37:22
◼
►
based macbook pros were supposed to be
[TS]
00:37:24
◼
►
out by now and I see that they were
[TS]
00:37:26
◼
►
probably delayed because of various
[TS]
00:37:28
◼
►
Intel issues like you like it if you
[TS]
00:37:30
◼
►
heard like it every time you mention
[TS]
00:37:32
◼
►
skylight and laptops we
[TS]
00:37:33
◼
►
usually hear from people who tell us
[TS]
00:37:34
◼
►
that like the that sky like ships that
[TS]
00:37:38
◼
►
were there would be appropriate for the
[TS]
00:37:39
◼
►
15-inch were kind of out in the pc world
[TS]
00:37:41
◼
►
and they actually had tons of problems
[TS]
00:37:43
◼
►
and like that they were it seemed like
[TS]
00:37:45
◼
►
intimate like partly may be recalled
[TS]
00:37:47
◼
►
them or something that was there were
[TS]
00:37:49
◼
►
some problems with them that that that
[TS]
00:37:51
◼
►
the manufacturer having even after it
[TS]
00:37:53
◼
►
shipped so it seems like there's some
[TS]
00:37:54
◼
►
kind of unexpected Intel delay that
[TS]
00:37:56
◼
►
caused the macbook pros to most likely
[TS]
00:37:58
◼
►
be delayed so it seems like if Apple's
[TS]
00:38:00
◼
►
gonna release a new 5k display would
[TS]
00:38:02
◼
►
need sky like most likely to drive it so
[TS]
00:38:05
◼
►
that they were probably planning on
[TS]
00:38:06
◼
►
releasing the 5k external display that
[TS]
00:38:09
◼
►
succeeded this thunderbolt display at
[TS]
00:38:11
◼
►
the same time as new macbook pros that
[TS]
00:38:13
◼
►
we're all supposed to already be out by
[TS]
00:38:14
◼
►
now so chances are they'd probably like
[TS]
00:38:17
◼
►
you know gave the gave the order months
[TS]
00:38:20
◼
►
ago to like stop taking these component
[TS]
00:38:22
◼
►
orders stop making these things you know
[TS]
00:38:24
◼
►
stop manufacturing these and then this
[TS]
00:38:26
◼
►
delay happened sometime in the meantime
[TS]
00:38:28
◼
►
this was probably just like the
[TS]
00:38:30
◼
►
replacement product was supposed to be
[TS]
00:38:32
◼
►
out by now and it might be done but
[TS]
00:38:34
◼
►
there's no computer that can drive it
[TS]
00:38:35
◼
►
yet so they're not going to release a
[TS]
00:38:37
◼
►
display with no computer that can drive
[TS]
00:38:39
◼
►
it so they kind of held the display for
[TS]
00:38:42
◼
►
the macbook pro which got delayed so now
[TS]
00:38:45
◼
►
they just have well we already told the
[TS]
00:38:47
◼
►
manufacturing line to stop making these
[TS]
00:38:49
◼
►
and we're not gonna start back up again
[TS]
00:38:51
◼
►
because that's crazy so I'm guessing
[TS]
00:38:54
◼
►
words it is weird hole in the middle of
[TS]
00:38:56
◼
►
this like you know this visit these
[TS]
00:38:58
◼
►
weird delays caused this this operations
[TS]
00:39:01
◼
►
whole to happen and it will make sense
[TS]
00:39:03
◼
►
in a few months or whatever you know
[TS]
00:39:04
◼
►
whenever the numerical approach come out
[TS]
00:39:05
◼
►
and by the way i think the reason
[TS]
00:39:07
◼
►
they're gonna make this product i was
[TS]
00:39:08
◼
►
like maybe they're not gonna sell
[TS]
00:39:09
◼
►
external displays the reason I make it
[TS]
00:39:11
◼
►
is because the margins have to be pretty
[TS]
00:39:13
◼
►
darn good
[TS]
00:39:13
◼
►
oh yeah probably to sell it for the same
[TS]
00:39:15
◼
►
but you know for the same kind of margin
[TS]
00:39:16
◼
►
thunderbolt display like that was a
[TS]
00:39:18
◼
►
thousand-dollar monitor and age when you
[TS]
00:39:20
◼
►
could get monitors with sometimes
[TS]
00:39:22
◼
►
monitor the exact same panel in them for
[TS]
00:39:24
◼
►
less money if you knew the right to know
[TS]
00:39:26
◼
►
the right weirdly number del thing or
[TS]
00:39:27
◼
►
whatever to buy like a good healthy
[TS]
00:39:30
◼
►
margins on those and apple sells mostly
[TS]
00:39:32
◼
►
laptops for people who by Max and people
[TS]
00:39:35
◼
►
with laptops often want a really big
[TS]
00:39:38
◼
►
external display like that they don't
[TS]
00:39:39
◼
►
want an external display that's like
[TS]
00:39:40
◼
►
seventeen inches but if people want
[TS]
00:39:42
◼
►
external display they want a really big
[TS]
00:39:44
◼
►
one and so Apple should sell you really
[TS]
00:39:46
◼
►
because it's you know the same reason
[TS]
00:39:47
◼
►
cell battery cases for granted a lot of
[TS]
00:39:49
◼
►
there's this is a product that people
[TS]
00:39:50
◼
►
want and we can sell it at high margin
[TS]
00:39:52
◼
►
and they can look nice and Johnny iphone
[TS]
00:39:54
◼
►
won't be upset by someone connecting a
[TS]
00:39:57
◼
►
disgusting looking dell monitor to their
[TS]
00:39:59
◼
►
beautiful macbook pro like all signs
[TS]
00:40:01
◼
►
point towards Apple continuing to sell
[TS]
00:40:03
◼
►
one really big really expensive
[TS]
00:40:04
◼
►
high-margin external monitor and all
[TS]
00:40:07
◼
►
signs point to me buying one once i can

00:40:09
◼
►
hook it up to a computer

things when like is that from official i

presentation at the time we recorded the
[TS]
00:42:13
◼
►
wrec episode we had not seen this
[TS]
00:42:15
◼
►
presentation yet because it was two days
[TS]
00:42:17
◼
►
in the future and there wasn't much new
[TS]
00:42:19
◼
►
information in that thing that wasn't
[TS]
00:42:21
◼
►
already in the state unit but there were
[TS]
00:42:23
◼
►
two tidbits worth discussing one is
[TS]
00:42:27
◼
►
right so a PFS as we saw in the state of
[TS]
00:42:29
◼
►
union is is like it will be a developer
[TS]
00:42:32
◼
►
preview i think a lot of people are
[TS]
00:42:33
◼
►
confused by that like okay everything's
[TS]
00:42:35
◼
►
developer preview right but now when
[TS]
00:42:37
◼
►
Sierra ships for real like the final
[TS]
00:42:39
◼
►
version of ships to customers a PFS will
[TS]
00:42:41
◼
►
be included in Sierra as a developer
[TS]
00:42:44
◼
►
preview as and you will get the official
[TS]
00:42:45
◼
►
release version of Sierra and part of it
[TS]
00:42:48
◼
►
of that product will be provisional
[TS]
00:42:51
◼
►
developer level support for a PFS so
[TS]
00:42:53
◼
►
what does that mean for you know our how
[TS]
00:42:56
◼
►
far in the future is a PFS as they said
[TS]
00:42:58
◼
►
in the State of the Union a PFS is
[TS]
00:42:59
◼
►
developer preview this year and coming
[TS]
00:43:01
◼
►
in 2017 but what does that even mean
[TS]
00:43:03
◼
►
i slide in Section 701 have these words
[TS]
00:43:06
◼
►
on it and we'll see how this rolls out a
[TS]
00:43:09
◼
►
PFS will be the default file system for
[TS]
00:43:11
◼
►
all apple products in 2017 so that is
[TS]
00:43:15
◼
►
pretty unequivocal except for the part
[TS]
00:43:17
◼
►
where it says 2017 so default fastest
[TS]

we'll see if they made it so that seemed

to me like an ambitious goal but I'm

also kind of excited about it because of

00:44:09

a little 2017 is the year the filesystem

really hope that goes well you know or I

suppose they could say okay well again

if they go December 31st 2017 then next

then December 31st sergeant all the

products will be former that way so in

00:44:43
◼

case anyone at Apple anyone who knows
[TS]
00:44:46
◼

any of the Apple filesystem people is
[TS]
00:44:48

listening right now consider that John
[TS]

syracuse your friend of mine has been
[TS]
00:44:53
◼

asking for a new file system for years
[TS]
00:44:54
◼

has been begging for a new file system
[TS]
00:44:57
◼
►
and as he just said you guys you know
[TS]
00:45:00
◼
►
Apple is said in 2017 i would just like
[TS]
00:45:03
◼
►
to point out that John Sarah's key stop
[TS]
00:45:06
◼
►
John circus birthday happens to be the
[TS]
00:45:09
◼
►
very last day of 2017 if you just
[TS]
00:45:12
◼
►
decided but you know maybe maybe that
[TS]
00:45:14
◼
►
would be the appropriate day to flip the
[TS]
00:45:16
◼
►
switch and hit the big red button that
[TS]
00:45:18
◼
►
would be a pretty solid birthday present
[TS]
00:45:19
◼
►
a much better present I've ever gotten
[TS]
00:45:20
◼
►
John just throwing it out there guys you
[TS]
00:45:22
◼
►
run with it
[TS]
00:45:23
◼
►
yeah I think they're gonna go before
[TS]
00:45:26
◼
►
that and my impression is that this date
[TS]
00:45:29
◼
►
even though it seems ambitious to us is
[TS]
00:45:31
◼
►
not really that ambitious from the
[TS]
00:45:33
◼
►
perspective of Apple who has been
[TS]
00:45:34
◼
►
working on the sauces for a long time
[TS]
00:45:36
◼
►
obviously like they didn't just
[TS]
00:45:37
◼
►
announced that they started working at
[TS]
00:45:38
◼
►
last week right so the impression I get
[TS]
00:45:42
◼
►
from WTC is that 2017 is not rushing it
[TS]
00:45:46
◼
►
and they really got the whole year it's
[TS]
00:45:48
◼
►
like you know it's a relaxing expanse of
[TS]
00:45:50
◼
►
time in which they can plan their roll
[TS]
00:45:52
◼
►
out of this new files and I really hope
[TS]
00:45:54
◼
►
that's true because if so that's exactly
[TS]
00:45:55
◼
►
how you want to do this the second
[TS]
00:45:58
◼
►
tidbit that was in this WC session which
[TS]
00:46:00
◼
►
i'm sure everyone knows by now it's
[TS]
00:46:01
◼
►
about all the Apple news sites is the
[TS]
00:46:04
◼
►
question of if you don't buy a new piece
[TS]
00:46:07
◼
►
of hardware and
[TS]
00:46:07
◼
►
which comes with a PFS that but you have
[TS]
00:46:10
◼
►
an existing piece of hardware
[TS]
00:46:12
◼
►
how do you get a PFS like I can only
[TS]
00:46:15
◼
►
think about the perspective of a Mac
[TS]
00:46:17
◼
►
because i don't imagine they're going to
[TS]
00:46:18
◼
►
let people like a reformat their iphones
[TS]
00:46:20
◼
►
like if you restore your iphone in 2017
[TS]
00:46:23
◼
►
in the post a PFS world is reformatted
[TS]
00:46:25
◼
►
with a PFS i doubt it but certainly for
[TS]
00:46:27
◼
►
the mac we know this is a
[TS]
00:46:29
◼
►
straightforward situation the way you
[TS]
00:46:31
◼
►
could do it is you backup your entire
[TS]
00:46:33
◼
►
hard drive your race it you reformat it
[TS]
00:46:34
◼
►
is a PFS and you restore your hard drive
[TS]
00:46:36
◼
►
on you can do a time machine go to a
[TS]
00:46:38
◼
►
super-duper is lots of different
[TS]
00:46:39
◼
►
solutions to doing this all those should
[TS]
00:46:42
◼
►
be possible but in the 701 presentation
[TS]
00:46:44
◼
►
wdc apple said that I have something
[TS]
00:46:46
◼
►
else in mind and that is in place
[TS]
00:46:48
◼
►
conversion of your volume format from
[TS]
00:46:51
◼
►
hfs+ to a PFS so you've got a mac this
[TS]
00:46:55
◼
►
file system comes out in 2017 it's
[TS]
00:46:56
◼
►
officially released all the new hardware
[TS]
00:46:58
◼
►
you by comes with that you're like I
[TS]
00:46:59
◼
►
want to try the new files and what do i
[TS]
00:47:01
◼
►
do well first of all i would advise you
[TS]
00:47:03
◼
►
to make a backup anyway and maybe two
[TS]
00:47:05
◼
►
backups and maybe three backups but you
[TS]
00:47:08
◼
►
won't have to erase your disc you'll be
[TS]
00:47:10
◼
►
able to take your existing disc is
[TS]
00:47:12
◼
►
formatted with hfs+ and do a thing and
[TS]
00:47:15
◼
►
reboot and when it comes back it all
[TS]
00:47:18
◼
►
your data will still be there you won't
[TS]
00:47:20
◼
►
have erased it and it will be in a PFS
[TS]
00:47:22
◼
►
volume and the the concept of this is
[TS]
00:47:26
◼
►
freaking people i think i talked about
[TS]
00:47:27
◼
►
the old al soft plus maker thing that
[TS]
00:47:29
◼
►
would do the same conversion for from HS
[TS]
00:47:32
◼
►
hfs+ in place and it was terrifying
[TS]
00:47:34
◼
►
because it's screwed up in the middle
[TS]
00:47:35
◼
►
you are left with nothing
[TS]
00:47:36
◼
►
this is the situation with ApS is a
[TS]
00:47:40
◼
►
little bit different and you shouldn't
[TS]
00:47:42
◼
►
actually be as terrified as you are
[TS]
00:47:45
◼
►
it actually is it if you've ever seen
[TS]
00:47:47
◼
►
from I don't know what some ATP or maybe
[TS]
00:47:50
◼
►
use hypercritical the btrfs demo of a
[TS]
00:47:54
◼
►
similar type of in place conversion new
[TS]
00:47:56
◼
►
it's the same type of deal because of
[TS]
00:47:58
◼
►
the way this volume format works it's
[TS]
00:48:00
◼
►
actually fairly safe so here's here's
[TS]
00:48:03
◼
►
the process and here's why it will not
[TS]
00:48:05
◼
►
probably destroy your data although
[TS]
00:48:07
◼
►
definitely making backups
[TS]
00:48:08
◼
►
so the first thing is going to do is
[TS]
00:48:10
◼
►
going to unmount your volume so
[TS]
00:48:11
◼
►
obviously you can't be booted from your
[TS]
00:48:12
◼
►
volume to reformat the boot of the
[TS]
00:48:14
◼
►
recovery partition or something like
[TS]
00:48:16
◼
►
that or what
[TS]
00:48:16
◼
►
but everyone sits unmounted no more
[TS]
00:48:19
◼
►
changes are happening to this volume
[TS]
00:48:20
◼
►
you're going to convert so you don't
[TS]
00:48:22
◼
►
have to worry about chasing after some
[TS]
00:48:24
◼
►
other changes that's not gonna happen
[TS]
00:48:25
◼
►
live like the one called filevault
[TS]
00:48:27
◼
►
conversion where you can encrypt ask why
[TS]
00:48:29
◼
►
using which is kind of magical this is
[TS]
00:48:30
◼
►
like unmounted alright next thing is
[TS]
00:48:33
◼
►
it's going to write all the a PFS
[TS]
00:48:35
◼
►
metadata structures all the little
[TS]
00:48:36
◼
►
pointers to wear this file begin where
[TS]
00:48:39
◼
►
is the den how many blocks are in it of
[TS]
00:48:41
◼
►
what is the file call but all the dates
[TS]
00:48:43
◼
►
about the files going to write all that
[TS]
00:48:44
◼
►
metadata to the free space on the HFS
[TS]
00:48:47
◼
►
plus volume so you can only do this
[TS]
00:48:48
◼
►
conversion if you have enough free space
[TS]
00:48:49
◼
►
to fit the metadata I don't know how
[TS]
00:48:51
◼
►
much it's gonna take but you do need
[TS]
00:48:52
◼
►
some free space and hopefully hear it
[TS]
00:48:53
◼
►
just isn't filled to the brim anyway so
[TS]
00:48:56
◼
►
it's writing just to the to the free
[TS]
00:48:58
◼
►
area so at any point during this process
[TS]
00:49:00
◼
►
when it's writing always meditating when
[TS]
00:49:01
◼
►
it's it's reading your hfs+ volume
[TS]
00:49:03
◼
►
finding out where everything is what
[TS]
00:49:04
◼
►
everything is called with all the dates
[TS]
00:49:06
◼
►
are all permissions are all the
[TS]
00:49:07
◼
►
ownership all everything about these
[TS]
00:49:08
◼
►
files all the different for call the
[TS]
00:49:10
◼
►
extended afterwards all that stuff and
[TS]
00:49:12
◼
►
it's writing that metadata doubt in a
[TS]
00:49:13
◼
►
PFS format to the free space if at any
[TS]
00:49:16
◼
►
time something bad happens during this
[TS]
00:49:17
◼
►
like someone yanked the plug in your
[TS]
00:49:18
◼
►
computer your hfs+ volume is fine
[TS]
00:49:21
◼
►
because if you reboot into it it doesn't
[TS]
00:49:22
◼
►
care what's in the free space like this
[TS]
00:49:24
◼
►
garbage in the free space it's free
[TS]
00:49:25
◼
►
space on hfs+ I'm nothing is wrong with
[TS]
00:49:27
◼
►
it is perfectly fine
[TS]
00:49:28
◼
►
this is the majority of the time it
[TS]
00:49:30
◼
►
spends is looking at all your things in
[TS]
00:49:32
◼
►
writing all the metadata for all the
[TS]
00:49:34
◼
►
things on your file system when it's
[TS]
00:49:37
◼
►
finally finished doing that all it needs
[TS]
00:49:39
◼
►
to do is this is one of the critical
[TS]
00:49:40
◼
►
section when things go wrong and the
[TS]
00:49:42
◼
►
critical section should be very very
[TS]
00:49:43
◼
►
short it's basically delete the HFS plus
[TS]
00:49:46
◼
►
superblock update the position type to
[TS]
00:49:48
◼
►
be a PFS put the correct uuid in there
[TS]
00:49:51
◼
►
and you're done
[TS]
00:49:51
◼
►
like you just have to do a switcheroo in
[TS]
00:49:53
◼
►
the front of the whole file systems ok
[TS]
00:49:54
◼
►
now you're not HFS anymore
[TS]
00:49:56
◼
►
now you're a PFS and then you reboot and
[TS]
00:49:58
◼
►
that critical section when something can
[TS]
00:50:00
◼
►
go wrong like they're halfway through i
[TS]
00:50:01
◼
►
bet even that probably is fairly well
[TS]
00:50:03
◼
►
protected because i know i guess once
[TS]
00:50:06
◼
►
you delete the eventual hfs+ abroad kind
[TS]
00:50:08
◼
►
of scared but anyway this is a very
[TS]
00:50:10
◼
►
small window of time and something can
[TS]
00:50:11
◼
►
go wrong all the rest of time during the
[TS]
00:50:14
◼
►
conversion everything is fine and I bet
[TS]
00:50:15
◼
►
you could probably restore the HS plus
[TS]
00:50:17
◼
►
superblock if you were clever enough for
[TS]
00:50:19
◼
►
some recovery program could do that as
[TS]
00:50:21
◼
►
well because again you haven't touched
[TS]
00:50:22
◼
►
any of the actual data your actual files
[TS]
00:50:24
◼
►
have not been modified hfs+ metadata is
[TS]
00:50:27
◼
►
not been modified none of that stuff has
[TS]
00:50:29
◼
►
changed sitting exact
[TS]
00:50:30
◼
►
where it was all you gotta do is change
[TS]
00:50:33
◼
►
sort of that the thing that tells you
[TS]
00:50:34
◼
►
where everything else in the file system
[TS]
00:50:35
◼
►
is the superblock is metadata about the
[TS]
00:50:37
◼
►
whole file system that tells it you know
[TS]
00:50:39
◼
►
how big the file system is and where all
[TS]
00:50:40
◼
►
the other metadata structures aren't all
[TS]
00:50:42
◼
►
that stuff and by the way speaking of
[TS]
00:50:44
◼
►
the apsu idea the thing that tells it
[TS]
00:50:46
◼
►
like what volume type this is one other
[TS]
00:50:48
◼
►
tidbits that was sort of alluded to in
[TS]
00:50:50
◼
►
state of the union and I think in the
[TS]
00:50:52
◼
►
seventh one thing is that if you have an
[TS]
00:50:54
◼
►
aps IPS volume and you try to mount it
[TS]
00:50:59
◼
►
unlike an older Mac operating system
[TS]
00:51:01
◼
►
it'll say this disc is unreadable you
[TS]
00:51:02
◼
►
want to initialize it all that business
[TS]
00:51:04
◼
►
but if you try to do that on El Capitan
[TS]
00:51:06
◼
►
it won't do that
[TS]
00:51:07
◼
►
not because I can't have Secret support
[TS]
00:51:08
◼
►
maybe FS but just because it know it
[TS]
00:51:11
◼
►
recognizes the uuid so won't offer to
[TS]
00:51:13
◼
►
erase it for you and that's I guess to
[TS]
00:51:15
◼
►
try to prevent people from accidentally
[TS]
00:51:17
◼
►
erasing their newly converted disk when
[TS]
00:51:19
◼
►
they don't realize that prompt asking
[TS]
00:51:20
◼
►
them to erase it was actually asking
[TS]
00:51:22
◼
►
them to erase the disc latest converted
[TS]
00:51:24
◼
►
so that's that's kind of clever and
[TS]
00:51:26
◼
►
that's another secret thing you would
[TS]
00:51:28
◼
►
never have known of you you're not going
[TS]
00:51:29
◼
►
to be searching the el capitan binaries
[TS]
00:51:31
◼
►
for a uuid because you never find it
[TS]

because it's all nonsense but anyway I
[TS]
00:51:36
◼
►
assume that I will do this in place
[TS]
00:51:38
◼
►
conversion again after making many many
[TS]
00:51:40
◼
►
backups but both in theory and practice
[TS]
00:51:43
◼

this conversion method of writing new
[TS]
00:51:46
◼

metadata structures to free space
[TS]
00:51:47
◼
►
pointing at the data in where it already
[TS]
00:51:50
◼

exists is fairly well-established not
[TS]
00:51:52
◼
►
something crazy that we came up with its
[TS]
00:51:54
◼
►
own and so I'm pretty confident that
[TS]
00:51:56
◼

this will actually work and it will seem
[TS]
00:51:58
◼
►
like magic
[TS]
00:51:59
◼
►
that's pretty high praise I am very
[TS]
00:52:01
◼

impressed
[TS]
00:52:02
◼
►
why is it have the P in the name
[TS]
00:52:06
◼
►
why not AFS oh yeah so that's a question
[TS]
00:52:09
◼
►
I asked some of the filesystem people
[TS]
00:52:12
◼
►
WBC and it says we speculate like we
[TS]
00:52:15
◼
►
can't use AFS because that's already
[TS]
00:52:16
◼
►
Andrew filesystem and you go through
[TS]
00:52:19
◼
►
every letter in the alphabet a lot of
[TS]
00:52:20
◼
►
them were taken already
[TS]
00:52:21
◼
►
every combination of two letters either
[TS]
00:52:23
◼
►
taken or nonsensical a PFS is not great
[TS]
00:52:27
◼
►
as an acronym but it's probably better
[TS]
00:52:29
◼
►
than AFS it's probably better than ifs
[TS]
00:52:31
◼
►
which i think is also already taken lots
[TS]
00:52:34
◼
►
of cool letters like CFS and XFS are
[TS]
00:52:36
◼
►
already taken my complaint was why isn't
[TS]
00:52:39
◼
►
it a cool name why isn't it like forget
[TS]
00:52:40
◼
►
about the four-letter actor
[TS]
00:52:41
◼
►
I'm gonna give it whatever four-letter
[TS]
00:52:42
◼
►
three or four little letter you know
[TS]
00:52:44
◼
►
abbreviation that you want
[TS]
00:52:46
◼
►
why isn't it have a cool name like I
[TS]
00:52:48
◼
►
don't know like thunder FS swiftor you
[TS]
00:52:52
◼
►
know grand central dispatch or whatever
[TS]
00:52:54
◼
►
like with the trains yeah like you come
[TS]
00:52:56
◼
►
up with a cool marketing name for it and
[TS]
00:52:59
◼
►
the upshot seems to be that file systems
[TS]
00:53:03
◼
►
are not something that most users know
[TS]
00:53:05
◼
►
about certainly on iphones no one knows
[TS]
00:53:07
◼
►
what the file system isn't even imax
[TS]
00:53:08
◼
►
people don't know the only time people
[TS]
00:53:11
◼
►
are likely to encounter is if you're on
[TS]
00:53:13
◼
►
a Mac and you go to disk utility or
[TS]
00:53:14
◼
►
something you're trying to format in
[TS]
00:53:15
◼
►
your disk or like you get info on it is
[TS]
00:53:18
◼
►
can you seem to get info window but
[TS]
00:53:19
◼
►
especially when you format your desk
[TS]
00:53:21
◼
►
says I know how do you want to what
[TS]
00:53:22
◼
►
volume format you want to use for this
[TS]
00:53:24
◼
►
disc and disk utility I think and do a
[TS]
00:53:26
◼
►
bunch of different formats or even you
[TS]
00:53:28
◼
►
know that OS 10 can I was ten whatever
[TS]
00:53:30
◼
►
that operating system is called ya Mac
[TS]
00:53:32
◼
►
OS can mount a lot of the things you
[TS]
00:53:34
◼
►
come out like fat TX pad and like all
[TS]
00:53:38
◼
►
these weird need all the all the weird
[TS]
00:53:39
◼
►
CD file systems and stuff sometimes if
[TS]
00:53:42
◼
►
you present the user with this popup
[TS]
00:53:43
◼
►
menu of like who are you know what
[TS]
00:53:46
◼
►
volume for what you want to make this or
[TS]
00:53:47
◼
►
what going forward is this they don't
[TS]
00:53:48
◼
►
know what all those things mean they
[TS]
00:53:49
◼
►
don't know what hfs+ means they don't
[TS]
00:53:51
◼
►
know what Apple extended journaled
[TS]
00:53:52
◼
►
whatever case they don't know what those
[TS]
00:53:54
◼
►
things being at all so they go the whole
[TS]
00:53:57
◼
►
of a PFS and it's a reasonable goal is
[TS]
00:53:59
◼
►
to put an entry on that list that is
[TS]
00:54:01
◼
►
absolutely clear that that's the one
[TS]
00:54:03
◼
►
that they want and and so if you have a
[TS]
00:54:04
◼
►
pop-up menu and your formatting a disk
[TS]
00:54:06
◼
►
and you don't know what the hell you
[TS]
00:54:07
◼
►
want to pick and you see one called
[TS]
00:54:08
◼
►
apple file system you can pick that one
[TS]
00:54:10
◼
►
was like all right this is an apple I
[TS]
00:54:12
◼
►
see a logo in front of me there's one on
[TS]
00:54:14
◼
►
the corner of the screen
[TS]
00:54:15
◼
►
I guess I want Apple filesystem and you
[TS]
00:54:17
◼
►
know what that'll be the right answer
[TS]
00:54:18
◼
►
you do want Apple filesystem you do not
[TS]
00:54:20
◼
►
want you know Apple extended journaled
[TS]
00:54:24
◼
►
whatever you want Apple file system so
[TS]
00:54:26
◼
►
as boring as it maybe it makes sense
[TS]
00:54:29
◼
►
from a user perspective that a user
[TS]
00:54:31
◼
►
should never have to see this would be
[TS]
00:54:32
◼
►
when they do see if they have no idea
[TS]
00:54:34
◼
►
what all those weird names mean they
[TS]
00:54:35
◼
►
just want to pick them on this Apple
[TS]
00:54:36
◼
►
sauces but don't you think there might
[TS]
00:54:38
◼
►
be like a problem well that one has a
[TS]
00:54:40
◼
►
this one sounds deluxe like it the more
[TS]
00:54:42
◼
►
words like it sound like that's the
[TS]
00:54:44
◼
►
deluxe cool option i guess maybe I want
[TS]
00:54:46
◼
►
the what it whatever journaling means
[TS]
00:54:48
◼
►
that's like journaling that's the
[TS]
00:54:51
◼
►
presence of the prosumer problem that
[TS]
00:54:53
◼
►
maybe those people you know their own
[TS]
00:54:55
◼
►
worst enemy but regular people are just
[TS]
00:54:57
◼
►
gonna pick the safest one they're not
[TS]
00:54:58
◼
►
gonna say maybe I don't know what
[TS]
00:54:59
◼
►
journal mean but I want to maybe better
[TS]
00:55:01
◼
►
what about extended that's better what
[TS]
00:55:02
◼
►
about exfat I like balances gotta XCX
[TS]
00:55:06
◼
►
and I think they're just gonna pick
[TS]
00:55:08
◼
►
apple blossom anyway it's a boring name
[TS]
00:55:11
◼
►
but it's certainly a straightforward
[TS]
00:55:12
◼
►
name and it is a forward-looking name in
[TS]
00:55:15
◼
►
that Apple feels like yes this is the
[TS]
00:55:16
◼
►
Apple file system now 30 years from now
[TS]
00:55:19
◼
►
on this is old and busted they might
[TS]
00:55:21
◼
►
have a problem because what he called
[TS]
00:55:22
◼
►
the next one but for now Apple file
[TS]
00:55:24
◼
►
system works and because they can't use
[TS]
00:55:26
◼
►
a FS a PFS is the awkward abbreviation
[TS]
00:55:30
◼
►
for Apple filesystem honest question do
[TS]
00:55:32
◼
►
you honestly think that when this file
[TS]
00:55:34
◼
►
system is outdated
[TS]
00:55:35
◼
►
we will still even have the option to
[TS]
00:55:38
◼
►
format our own partitions they look at
[TS]
00:55:40
◼
►
iOS iOS just give us any options you're
[TS]
00:55:42
◼
►
still going to have to read the aps best
[TS]
00:55:44
◼
►
formatted volumes I don't know you the
[TS]
00:55:46
◼
►
question is whether the mac will still
[TS]
00:55:48
◼
►
be around them because you don't have
[TS]
00:55:49
◼
►
you don't see volumes on iPads and apple
[TS]
00:55:52
◼
►
TV or the watch or iPhones so we'll see
[TS]
00:55:55
◼
►
but maybe they're out i mean at this
[TS]
00:55:56
◼
►
point I think we're lucky that we even
[TS]
00:55:58
◼
►
still have disk utility I mean barely
[TS]
00:56:00
◼
►
but i think we get we get all I I'd be
[TS]
00:56:04
◼
►
surprised if if we still have the
[TS]
00:56:07
◼
►
ability to format disk the way we want
[TS]
00:56:09
◼
►
to in front position we want to you know
[TS]
00:56:11
◼
►
in even 10 years
[TS]
00:56:13
◼
►
yeah well it could be if the file system
[TS]
00:56:15
◼
►
continues to to be pushed towards the
[TS]
00:56:18
◼
►
geeky side of things then they're free
[TS]
00:56:19
◼
►
to do whatever they want like sort of
[TS]
00:56:20
◼
►
like it
[TS]
00:56:21
◼
►
grand central dispatch is the marketing
[TS]
00:56:23
◼
►
name but live dispatch is the library
[TS]
00:56:25
◼
►
name on disk it's just a clear
[TS]
00:56:27
◼
►
separation between the names they
[TS]
00:56:29
◼
►
present in the marketing and the actual
[TS]
00:56:31
◼
►
names the programmers know them by so
[TS]
00:56:32
◼
►
may become less important
[TS]
00:56:34
◼
►
finally when it in 30 years when this
[TS]
00:56:37
◼
►
opera windows file system is outdated
[TS]
00:56:40
◼
►
and being replaced by the next file
[TS]
00:56:42
◼
►
system can we get together when you are
[TS]
00:56:45
◼
►
like what 7271 at that point and and do
[TS]
00:56:50
◼
►
a podcast then with with development by
[TS]
00:56:52
◼
►
then I plan to build my kingdom
[TS]
00:56:53
◼
►
patagonia some
[TS]
00:56:55
◼
►
oh they have been they will probably
[TS]
00:56:58
◼
►
have the internet there and microphones
[TS]
00:57:00
◼
►
will probably still exists
[TS]
00:57:02
◼
►
I like throwing yet another reference
[TS]
00:57:04
◼
►
you guys don't get I knew that if anyone
[TS]
00:57:06
◼
►
have to know as a reference but I also
[TS]
00:57:07
◼
►
knew I did not get it
[TS]
00:57:09
◼
►
partial credit yeah I'll take it alright
[TS]
00:57:11
◼
►
do you want to start running through
[TS]
00:57:12
◼
►
some of the features do you want me to
[TS]
00:57:14
◼
►
prompt this how would you like to
[TS]
00:57:16
◼
►
proceed sir on this part i'm going to
[TS]
00:57:19
◼
►
talk a little bit about file names but i
[TS]
00:57:20
◼
►
thought this would be a good opportunity
[TS]
00:57:21
◼
►
to find out how much you guys know about
[TS]
00:57:24
◼
►
unicode not nearly enough i've read the
[TS]
00:57:27
◼
►
God whose at the school ski getting on
[TS]
00:57:31
◼
►
unicode string handling and I and I've
[TS]
00:57:33
◼
►
already forgotten all of it that you
[TS]
00:57:35
◼
►
Marco you come across this at all you
[TS]
00:57:37
◼
►
probably don't because i'm a string
[TS]
00:57:38
◼
►
takes care of it for you and you don't
[TS]
00:57:39
◼
►
even care what the internal
[TS]
00:57:40
◼
►
representation as you know what about in
[TS]
00:57:42
◼
►
PHP land you deal with and stuff when
[TS]
00:57:44
◼
►
you do web things dealing with the
[TS]
00:57:45
◼
►
Unicode and text and everything I know a
[TS]
00:57:48
◼
►
lot about unicode yes
[TS]
00:57:49
◼
►
alright well so this will be new casing
[TS]
00:57:52
◼
►
may be new to some people but I think we
[TS]
00:57:53
◼
►
have to go over a little bit of the
[TS]
00:57:55
◼
►
basics before explain what the deal is
[TS]
00:57:57
◼
►
whatever talk about this in context of a
[TS]
00:57:59
◼
►
PFS because because files have names and
[TS]
00:58:01
◼
►
your directories have names right so
[TS]
00:58:03
◼
►
when you talk about a file path which
[TS]
00:58:04
◼
►
uses and shop and Mac operating system
[TS]
00:58:06
◼
►
whereby cells that entire thing is
[TS]
00:58:09
◼
►
presented as a string and certainly
[TS]
00:58:10
◼
►
filenames represented in strings and you
[TS]
00:58:12
◼
►
would think this is a straightforward
[TS]
00:58:13
◼
►
thing like that nobody thinks about all
[TS]
00:58:15
◼
►
of course like files have names like
[TS]
00:58:16
◼
►
that's fine but names are strings and
[TS]
00:58:19
◼
►
strings are fiendishly complicated and
[TS]
00:58:21
◼
►
actually matters from the perspective of
[TS]
00:58:23
◼
►
the file system because it has to do a
[TS]
00:58:25
◼
►
lot of stuff with strings so the i guess
[TS]
00:58:28
◼
►
the easiest way for people to understand
[TS]
00:58:31
◼
►
this is that unicode is a is a standard
[TS]
00:58:35
◼
►
for defining all the different things
[TS]
00:58:38
◼
►
that go into making a string and things
[TS]
00:58:42
◼
►
in unicode identified by code points
[TS]
00:58:44
◼
►
that have numbers and this the numbers
[TS]
00:58:46
◼
►
go up really high
[TS]
00:58:47
◼
►
alright they start start long up really
[TS]
00:58:50
◼
►
really high guy says lots and lots of
[TS]
00:58:51
◼
►
things that you can put into strings and
[TS]
00:58:53
◼
►
languages in the United States and the
[TS]
00:58:57
◼
►
other thing to understand is that when
[TS]
00:58:58
◼
►
you write something out to disk or
[TS]
00:58:59
◼
►
stored in memory or whatever we tend to
[TS]
00:59:01
◼
►
break things up in two bites and
[TS]
00:59:04
◼
►
we have a day lettering system in
[TS]
00:59:06
◼
►
america and the sort of Western world
[TS]
00:59:09
◼
►
called a ski that defined a very small
[TS]
00:59:11
◼
►
number of numbers that correspond to
[TS]
00:59:14
◼
►
things that can be in a string and it
[TS]
00:59:18
◼
►
each one of them fit into a single bite
[TS]
00:59:20
◼
►
so all you know a through z 1 through
[TS]
00:59:23
◼
►
zero through nine all the punctuation
[TS]
00:59:25
◼
►
characters or whatever they all fit into
[TS]
00:59:26
◼
►
one bites is 255 possible combinations
[TS]
00:59:30
◼
►
and everybody was happy to realize that
[TS]
00:59:32
◼
►
there are other characters and other
[TS]
00:59:33
◼
►
languages they didn't fit right
[TS]
00:59:36
◼
►
so when I came up with unicode they
[TS]
00:59:38
◼
►
tried to be nice and give a ski all the
[TS]
00:59:40
◼
►
same numbers that it always had for
[TS]
00:59:42
◼
►
compatibility reasons but they just keep
[TS]
00:59:44
◼
►
going from there and a certain point you
[TS]
00:59:45
◼
►
get up two numbers unicode code points
[TS]
00:59:48
◼
►
that are way higher than 255 and when it
[TS]
00:59:51
◼
►
comes time for you to write them to disk
[TS]
00:59:53
◼
►
what do you do with those you can't just
[TS]
00:59:55
◼
►
write them out as the big numbers in a
[TS]
00:59:56
◼
►
series of bytes because the first bite
[TS]
00:59:58
◼
►
of the number might look like a cat
[TS]
00:59:58
◼
►
of the number might look like a cat
[TS]
01:00:00
◼
►
put a letter P or something right
[TS]
01:00:01
◼
►
because it's the same you know what i
[TS]
01:00:02

mean so they have come up with a series
[TS]
01:00:04
◼
►
of encoding systems where when you got
[TS]
01:00:06
◼
►
this big number that does not fit into a
[TS]
01:00:08
◼
►
single bite and you can't right the way
[TS]
01:00:10
◼
►
you would write that number out of
[TS]
01:00:11
◼
►
sequence of bytes we need some way to
[TS]
01:00:13
◼
►
encode these things one of the ways to
[TS]
01:00:15
◼
►
encode is instead of writing one code
[TS]
01:00:18
◼
►
point every bite right one co point
[TS]
01:00:20
◼
►
every 32 bits you have a huge space for
[TS]
01:00:23
◼
►
each one's your capital letter A instead
[TS]
01:00:24
◼
►
of taking up a single bite takes up what
[TS]
01:00:27
◼
►
is 32 4 bytes it bites
[TS]
01:00:29
◼
►
yeah it bites for but ya gotta go fa x 4
[TS]
01:00:33
◼
►
i'll get in a second anyway but that
[TS]
01:00:37
◼
►
would be incredibly wasteful because now
[TS]
01:00:39
◼
►
all of a sudden if you're writing
[TS]
01:00:40
◼
►
something an ascii text it would take up
[TS]
01:00:42
◼
►
four times as much room that's not good
[TS]
01:00:44
◼
►
there's also we could do it in 16 can be
[TS]
01:00:46
◼
►
doing 16 well we actually have more
[TS]
01:00:49
◼
►
unicode code points that fit into 16
[TS]
01:00:52
◼
►
bits but I think for a while maybe they
[TS]
01:00:54
◼
►
all fit in I think I string uses this
[TS]
01:00:57
◼
►
encoding called utf-16 internally
[TS]
01:00:59
◼
►
yeah i believe i believe the very first
[TS]
01:01:01
◼
►
version of unicode what that they did
[TS]
01:01:02
◼
►
all fit in and then you know once we
[TS]
01:01:04
◼
►
started realizing oh there's other parts
[TS]
01:01:06
◼
►
of the world and like ancient scripts
[TS]
01:01:08
◼
►
and different combining things and
[TS]
01:01:09
◼
►
there's all sorts of new stuff now don't
[TS]
01:01:11
◼
►
forget emoji yet that all came later
[TS]
01:01:13
◼
►
yeah but it's important
[TS]
01:01:15
◼
►
yeah that's not great either but it also
[TS]
01:01:16
◼
►
takes a lot of room and the one that's
[TS]
01:01:21
◼
►
been most common use these days is
[TS]
01:01:22
◼
►
called utf-8 which is a pretty clever
[TS]
01:01:24
◼
►
encoding scheme where a ski gets to be
[TS]
01:01:27
◼
►
exactly the way it normally is like so
[TS]
01:01:29
◼
►
you know one bite one bite for each
[TS]
01:01:31
◼
►
character and all the ones that are
[TS]
01:01:33
◼
►
bigger they have these unique sequences
[TS]
01:01:35
◼
►
of multiple bites you can I want you
[TS]
01:01:37
◼
►
know two bites three bites four bytes
[TS]
01:01:38
◼
►
that even up to five bites all these are
[TS]
01:01:41
◼
►
so that all the leading bites are not
[TS]
01:01:43
◼
►
are not mistaken for plain old ascii
[TS]
01:01:46
◼
►
characters or whatever and that's the
[TS]
01:01:48
◼
►
most common encoding use and this is
[TS]
01:01:51
◼
►
relevant because when you create a file
[TS]
01:01:53
◼
►
in first of all people don't want to use
[TS]
01:01:55
◼
►
a file system where you can only create
[TS]
01:01:56
◼
►
problems and is key because that would
[TS]
01:01:58
◼
►
be annoying for people who speak
[TS]
01:01:59
◼
►
languages other than English and even
[TS]
01:02:00
◼
►
annoying for English speakers because he
[TS]
01:02:01
◼
►
had curly quotes and stuff but you need
[TS]
01:02:05
◼
►
to write this you need to have the stuff
[TS]
01:02:07
◼
►
in memory and you needed to write it out
[TS]
01:02:08
◼
►
to disk so you need some sort of
[TS]
01:02:10
◼
►
representation and that's exactly what
[TS]
01:02:12
◼
►
encoding is doing unicode as they take
[TS]
01:02:13
◼
►
these unicode code points these big
[TS]
01:02:15
◼
►
numbers possibly very large numbers and
[TS]
01:02:17
◼
►
write them out in a series of bytes in a
[TS]
01:02:19
◼
►
way according to some standard right the
[TS]
01:02:23
◼
►
additional complication here in unicode
[TS]
01:02:26
◼
►
is that unicode code points
[TS]
01:02:27
◼
►
I've been trying to save this and trying
[TS]
01:02:28
◼
►
to say thing in other words instead of
[TS]
01:02:30
◼
►
saying character or letter because it's
[TS]
01:02:33
◼
►
way more complicated than that so a
[TS]
01:02:34
◼
►
unicode component might be like the
[TS]
01:02:36
◼
►
capital letter A and that's something
[TS]
01:02:38
◼
►
that everyone understands but a unicode
[TS]
01:02:40
◼
►
code point might also be something
[TS]
01:02:41
◼
►
called combining acute accent that when
[TS]
01:02:44
◼
►
this unicode point follows another
[TS]
01:02:47
◼
►
it combines to make what looks like one
[TS]
01:02:50
◼
►
thing on your screen so if you did the
[TS]
01:02:52
◼
►
lowercase letter e plain old ascii
[TS]
01:02:55
◼
►
lowercase letter e followed by unicode
[TS]
01:02:57
◼
►
code point 301 which by the way is a
[TS]
01:02:59
◼
►
number bigger than 255 called combining
[TS]
01:03:02
◼
►
an acute accent you would get the e with
[TS]
01:03:05
◼
►
little line pointing up into the right
[TS]
01:03:06
◼
►
on top of it the acute accent so you can
[TS]
01:03:09
◼
►
write the word cafe CAF e combining
[TS]
01:03:12
◼
►
acute accent you get the word cafe with
[TS]
01:03:15
◼
►
the e with the little thing over it
[TS]
01:03:17
◼
►
right but you can write that same thing
[TS]
01:03:19
◼
►
cafe CAF and then he was a little thing
[TS]
01:03:21
◼
►
over in a different way you write CAF
[TS]
01:03:24
◼
►
just like a ski and then you can include
[TS]
01:03:26
◼
►
unicode code point e9 that's an index
[TS]
01:03:28
◼
►
latin small letter e with a cute you
[TS]
01:03:32
◼
►
look at another Road you know has two
[TS]
01:03:34
◼
►
ways for you to write something looks
[TS]
01:03:35
◼
►
the same on the page and i'm not sure
[TS]
01:03:39
◼
►
what the original motivation so it's
[TS]
01:03:41
◼
►
probably because you could use combining
[TS]
01:03:43
◼
►
characters and more flexible ways
[TS]
01:03:44
◼
►
including every possible combination but
[TS]
01:03:46
◼
►
sometimes combinations our community to
[TS]
01:03:48
◼
►
include this this comes with this adds
[TS]
01:03:50
◼
►
yet another wrinkle which is you can
[TS]
01:03:52
◼
►
write the same thing in unicode in
[TS]
01:03:54
◼
►
multiple different sequences of code
[TS]
01:03:55
◼
►
points that's a problem for something
[TS]
01:03:58
◼
►
like filesystem it's not a problem for
[TS]
01:04:00
◼
►
like if you're if you're writing a
[TS]
01:04:01
◼
►
report or printing a page or even making
[TS]
01:04:03
◼
►
a webpage but it's a problem for file
[TS]
01:04:04
◼
►
system so we just found something to
[TS]
01:04:05
◼
►
write file names out to disk like to
[TS]
01:04:08
◼
►
store them in the metadata somewhere and
[TS]
01:04:11
◼
►
in general filesystems don't want you to
[TS]
01:04:13
◼
►
be able to have a file with the
[TS]
01:04:14
◼
►
quote-unquote same name in the same
[TS]
01:04:16
◼
►
place ignoring filename extensions which
[TS]
01:04:19
◼
►
just make this mess but if you want to
[TS]
01:04:21
◼
►
make a file called cafe and then you
[TS]
01:04:22
◼
►
want to make another file called cafe
[TS]
01:04:24
◼
►
you wouldn't want them both to
[TS]
01:04:25
◼
►
the existing in the same folder staring
[TS]
01:04:27
◼
►
you in the face like how can these files
[TS]
01:04:28
◼
►
via they both have the same exact name
[TS]
01:04:30
◼
►
but if you were to merely write out the
[TS]
01:04:33
◼
►
encoded bites for this thing whether
[TS]
01:04:34
◼
►
it's utf-32 utf-8 utf-16 whatever
[TS]
01:04:37
◼
►
encoding format awesome chooses if you
[TS]
01:04:40
◼
►
just write them out at like that one
[TS]
01:04:42
◼
►
application could make CAF latin small
[TS]
01:04:45
◼
►
battery with a cute and one application
[TS]
01:04:46
◼
►
can make CFE combining acute accent as
[TS]
01:04:49
◼
►
far as the possum is concerned the
[TS]
01:04:51
◼
►
sequence of bytes of these files is
[TS]
01:04:52
◼
►
different so when it dips them it's an
[TS]
01:04:53
◼
►
open the file with this name i'll just
[TS]
01:04:54
◼
►
make this file but when you open the
[TS]
01:04:56
◼
►
folder you can see two files called cafe
[TS]
01:04:58
◼
►
and that is bad and i haven't even got
[TS]
01:05:01
◼
►
into case sensitivity because you can
[TS]
01:05:02
◼
►
see in case in case sensitivity
[TS]
01:05:04
◼
►
case-insensitive situation they have the
[TS]
01:05:06
◼
►
fastest has the same problem is they're
[TS]
01:05:09
◼
►
already a file with this name yes or no
[TS]
01:05:10
◼
►
and that's where you would factor in
[TS]
01:05:13
◼
►
okay well as their file with this name
[TS]
01:05:14
◼
►
but like the capitalized letters
[TS]
01:05:15
◼
►
lowercase you know ignoring case but
[TS]
01:05:17
◼
►
ignoring that entirely just for plain
[TS]
01:05:19
◼
►
old case sensitive whatever this
[TS]
01:05:21
◼
►
multiple ways you can write the same
[TS]
01:05:23
◼
►
word and unicode handles that by a
[TS]
01:05:25
◼
►
system that calls for a normalization
[TS]
01:05:27
◼
►
different normalized forms of unicode as
[TS]
01:05:30
◼
►
a bunch of different forms will link to
[TS]
01:05:31
◼
►
them in the show note what basically
[TS]
01:05:34
◼
►
comes down to is should we try to break
[TS]
01:05:37
◼
►
apart every character into its smallest
[TS]
01:05:38
◼
►
possible pieces decompose them you want
[TS]
01:05:41
◼
►
to have the lowercase C and then they'd
[TS]
01:05:42
◼
►
be combining accent or should we pride
[TS]
01:05:44
◼
►
try to compose them all into their
[TS]
01:05:47
◼
►
canonical form by squishing the e with
[TS]
01:05:49
◼
►
the combining accent into the latin
[TS]
01:05:50
◼
►
small letter e with the cute or should
[TS]
01:05:52
◼
►
we do different combinations of them in
[TS]
01:05:53
◼
►
different orders whole bunch of
[TS]
01:05:55
◼
►
different normalized forms the file
[TS]
01:05:56
◼
►
system if it wants to
[TS]
01:05:59
◼
►
well i was gonna say the processing has
[TS]
01:06:01
◼
►
to pick one of these but it doesn't it
[TS]
01:06:02
◼
►
could it could just the you know do what
[TS]
01:06:04
◼
►
I said in the NCAA i will accept
[TS]
01:06:06
◼
►
whatever bites you give me and I have no
[TS]
01:06:07
◼
►
idea what they mean
[TS]
01:06:08
◼
►
now just put them in the file system or
[TS]
01:06:10
◼
►
it could pick one of these normalized
[TS]
01:06:12
◼
►
forms you pick a normalized form then it
[TS]
01:06:13
◼
►
doesn't matter what the application
[TS]
01:06:14
◼
►
gives you it will always be canonicalize
[TS]
01:06:17
◼
►
when it goes to the file system so this
[TS]
01:06:19
◼
►
is what hfs+ does but of course hfs+
[TS]
01:06:21
◼
►
being a very old tile system does not
[TS]
01:06:23
◼
►
use any of the unicode normalized forms
[TS]
01:06:25
◼
►
it uses a variant of those normalized
[TS]
01:06:27
◼
►
form that has changed in different
[TS]
01:06:28
◼
►
versions of the operating system if you
[TS]
01:06:30
◼
►
look at a tech note 1150 from apple
[TS]
01:06:32
◼
►
which apparently is not no longer online
[TS]
01:06:34
◼
►
so we'll link to like another very
[TS]
01:06:36
◼
►
love it it uses kind of decomposed form
[TS]
01:06:40
◼
►
except for a whole bunch of Rangers that
[TS]
01:06:41
◼
►
it changes to be compatible like the mac
[TS]
01:06:43
◼
►
Greek encoding and it excludes a bunch
[TS]
01:06:46
◼
►
of things that it's really really
[TS]
01:06:47
◼
►
confusing but anyway hfs+ if you try to
[TS]
01:06:50
◼
►
make two files called cafe and I wrote
[TS]
01:06:53
◼
►
of course a little prescrip to test this
[TS]
01:06:54
◼
►
out and you try these two different ways
[TS]
01:06:56
◼
►
to do it
[TS]
01:06:57
◼
►
the with a combining accent and then the
[TS]
01:06:58
◼
►
e with a little hat already combined
[TS]
01:07:01
◼
►
doesn't matter what you write the over
[TS]
01:07:03
◼
►
the age of fossils like oh yeah I
[TS]
01:07:05
◼
►
totally made that file for you but when
[TS]
01:07:06
◼
►
you read that file back in and look at
[TS]
01:07:08
◼
►
the file name it will have changed it to
[TS]
01:07:11
◼
►
the the normalized form the HFS plus 1
[TS]
01:07:14
◼
►
so you will not make two separate files
[TS]
01:07:16
◼
►
if you try to make one file with that 11
[TS]
01:07:17
◼
►
name one follows the other name you will
[TS]
01:07:19
◼
►
just override the same file twice you
[TS]
01:07:21
◼
►
that like hfs+ does not take your
[TS]
01:07:24
◼
►
filename for what it is it does
[TS]
01:07:26
◼
►
something to eat first or rather the
[TS]
01:07:28
◼
►
driver for us plus those to be compliant
[TS]
01:07:29
◼
►
with the filesystem right this is one of
[TS]
01:07:31
◼
►
the reasons that a lot of units marriage
[TS]
01:07:33
◼
►
stuff and i think last torvalds had a
[TS]
01:07:34
◼
►
big rant about it but I couldn't find on
[TS]
01:07:36
◼
►
the internet have complained about hfs+
[TS]
01:07:38
◼
►
I gave you the file name is it supposed
[TS]
01:07:40
◼
►
to be this and you said no i totally
[TS]
01:07:42
◼
►
made that file for you and then later
[TS]
01:07:44
◼
►
when i try to read that final look at
[TS]
01:07:46
◼
►
its name it's not what I told you
[TS]
01:07:48
◼
►
and that's bad for things like get or
[TS]
01:07:50
◼
►
you know linux for that matter other
[TS]
01:07:51
◼
►
things the old files they don't expect
[TS]
01:07:53
◼
►
that to happen that the the sort of
[TS]
01:07:54
◼
►
unique style approaches here's a
[TS]
01:07:56
◼
►
sequence of bytes that makes up this
[TS]
01:07:57
◼
►
files named make that file and then
[TS]
01:08:01
◼
►
later when i read that file I'm going to
[TS]
01:08:03
◼
►
look at its name and better be that and
[TS]
01:08:05
◼
►
a better look it up with that name and
[TS]
01:08:06
◼
►
the name that comes on the disk better
[TS]
01:08:08
◼
►
with the bites i gave you and your dog
[TS]
01:08:09
◼
►
doesn't your father is broken but as I
[TS]
01:08:12
◼
►
hopefully explain if you do that it's
[TS]
01:08:14
◼
►
very easy for applications to make names
[TS]
01:08:17
◼
►
that look exactly the same in the user
[TS]
01:08:19
◼
►
interface cafe & cafe like they're
[TS]
01:08:21
◼
►
indistinguishable they're exactly the
[TS]
01:08:23
◼

same pixel for pixel because you can't
[TS]
01:08:25
◼
►
see the bites that make up the unicode
[TS]
01:08:27
◼
►
string you shouldn't care about them and
[TS]
01:08:28
◼
►
to users to be able to make the same
[TS]
01:08:30
◼
►
file with the same name with apparently
[TS]
01:08:32
◼
►
the same name that seems like a bug
[TS]
01:08:33
◼
►
seems like something should happen which
[TS]
01:08:35
◼
►
cafe file is the one that I want they
[TS]
01:08:36
◼
►
both have the same name I don't know
[TS]
01:08:38
◼
►
so you can't do that and that's why
[TS]
01:08:40
◼
►
apple doesn't do that a PFS now has to
[TS]
01:08:44
◼
►
make some decisions about this
[TS]
01:08:45
◼
►
what should a PFS do filename should do
[TS]
01:08:47
◼
►
it the HFS plus way exactly
[TS]
01:08:49
◼
►
but not because that's got years and
[TS]
01:08:51
◼
►
years of baggage floating around in it
[TS]
01:08:52
◼
►
from the fact that existed before
[TS]
01:08:54
◼
►
unicode I think you're leaving or maybe
[TS]
01:08:56
◼
►
just came out when you recover was very
[TS]
01:08:57
◼
►
young I think hfs+ hsps unicode but not
[TS]
01:09:00
◼
►
hfs+ anyway doing what a dress plus does
[TS]
01:09:04
◼
►
would be best for compatibility but it
[TS]
01:09:06
◼
►
would also be slightly crazy i don't
[TS]
01:09:07
◼
►
think Apple wants to maintain their
[TS]
01:09:10
◼
►
weird mapping tables forever with their
[TS]
01:09:13
◼
►
different uh you know non-standard
[TS]
01:09:15
◼
►
normalize forms should it do what many
[TS]
01:09:19
◼
►
linux file systems do many other
[TS]
01:09:20
◼
►
processes do which is I take no position
[TS]
01:09:22
◼
►
on file names that's not my concern you
[TS]
01:09:25
◼
►
gave me a sequence of bytes and that's
[TS]
01:09:26
◼
►
the file name i will write that out of
[TS]
01:09:27
◼
►
the filesystem later when you read it
[TS]
01:09:29
◼
►
you will get back that sequence of bytes
[TS]
01:09:30
◼
►
I don't know what sequence of bytes
[TS]
01:09:31
◼
►
means could mean anything i have no idea
[TS]
01:09:33
◼
►
what that stuff is but anyway here's
[TS]
01:09:34
◼
►
what you said
[TS]
01:09:36
◼
►
my understanding is that that's what a
[TS]
01:09:37
◼
►
PFS does today so if you run my little
[TS]
01:09:39
◼
►
prescription a PFS you can make two
[TS]
01:09:42
◼
►
files that apparently are both named
[TS]
01:09:44
◼
►
cafe but they're actually different
[TS]
01:09:46
◼
►
sequences of bytes because one uses the
[TS]
01:09:48
◼
►
combining acute accent the other one
[TS]
01:09:49
◼
►
uses the eve with a little accident he
[TS]
01:09:51
◼
►
composed on it and by the way i think i
[TS]
01:09:54
◼
►
think it might be no anyway when you if
[TS]
01:09:57
◼
►
you were to do this when i did in perl i
[TS]
01:09:59
◼
►
had to choose how to encode the filename
[TS]
01:10:01
◼
►
and I chose utf-8 I think you can't the
[TS]
01:10:05
◼
►
the API well i'm using / also has
[TS]
01:10:07
◼
►
different rules about that but the
[TS]
01:10:09
◼
►
bottom line is when you
[TS]
01:10:10
◼
►
somebody has to pick the bite
[TS]
01:10:11
◼
►
representation all right you can't give
[TS]
01:10:13
◼
►
it a sequence of bytes for your string
[TS]
01:10:15
◼
►
and use unicode code pointy nine or
[TS]
01:10:18
◼
►
unicode code point 301 because they
[TS]
01:10:19
◼
►
don't fit in a bite so you have to
[TS]
01:10:20
◼
►
figure out a way to put them in a bite
[TS]
01:10:21
◼
►
and that's what unicode encoding czar
[TS]
01:10:23
◼
►
and so I picked utf-8 if I'd given at
[TS]
01:10:25
◼
►
utf-16 i'm assuming you have stored
[TS]
01:10:27
◼
►
utf-16 and give me back utf-16 and so on
[TS]
01:10:30
◼
►
for all the other different coding think
[TS]
01:10:31
◼
►
so far as i can tell a PFS is a bag of
[TS]
01:10:34
◼
►
bytes that means its case sensitive
[TS]
01:10:35
◼
►
because bag of bytes means you gave me
[TS]
01:10:37
◼
►
these bites here these bites and so
[TS]
01:10:39
◼
►
another file comes along and wants to
[TS]
01:10:40
◼
►
write cafe with a lowercase C instead of
[TS]
01:10:42
◼
►
a capital C 2 different sequence of
[TS]
01:10:44
◼
►
bytes file system says no profile that
[TS]
01:10:46
◼
►
name here you go
[TS]
01:10:47
◼
►
I think this will i don't know i don't
[TS]
01:10:52
◼
►
think this is the official position
[TS]
01:10:53
◼
►
because ApS is not done
[TS]
01:10:55
◼
►
you can't even boot from it right now
[TS]
01:10:56
◼
►
it's obviously not finished
[TS]
01:10:59
◼
►
this is going to be looking for in the
[TS]
01:11:01
◼
►
coming mom
[TS]
01:11:02
◼
►
it's and the rest 2017 what will be the
[TS]
01:11:05
◼
►
policy and a PFS will they add case and
[TS]
01:11:08
◼
►
sensitivity once you decide that case
[TS]
01:11:10
◼
►
insensitivity you have to make some
[TS]
01:11:11
◼
►
decisions at the very least you have to
[TS]
01:11:13
◼
►
make decisions about encoding because
[TS]
01:11:15
◼
►
you can't compare case into things like
[TS]
01:11:17
◼
►
someone writes 15 min utf-16 and one
[TS]
01:11:19
◼
►
following utf-8 something in the in the
[TS]
01:11:22
◼
►
system has to understand that you can't
[TS]
01:11:25
◼
►
do complete comparisons with strings
[TS]
01:11:27
◼
►
encoded in different ways or maybe you
[TS]
01:11:29
◼
►
just straightforwardly compared as if I
[TS]
01:11:31
◼
►
know it doesn't make sense it makes
[TS]
01:11:32
◼
►
comparisons you have to have an
[TS]
01:11:34
◼
►
awareness of the encode right so if they
[TS]
01:11:36
◼
►
ever want to make a case insensitive
[TS]
01:11:37
◼
►
version of a PFS they need to decide
[TS]
01:11:41
◼
►
here's how file names are encoded and
[TS]
01:11:43
◼
►
then beyond that they have to make a
[TS]
01:11:45
◼
►
decision about normalization do we do
[TS]
01:11:47
◼
►
normalization at all if you don't do
[TS]
01:11:49
◼
►
normalization you can get into these
[TS]
01:11:50
◼
►
weird situations where you have files
[TS]
01:11:52
◼
►
with apparently the same name you could
[TS]
01:11:54
◼
►
handle this all at the framework level
[TS]
01:11:56
◼
►
and little cocoa and all and you know
[TS]
01:11:58
◼
►
whatever higher-level framework you like
[TS]
01:12:00
◼
►
it so on and so forth
[TS]
01:12:03
◼
►
I don't know if that's something that
[TS]
01:12:05
◼
►
will do and it's not i think this is not
[TS]
01:12:07
◼
►
a minor decision because what you decide
[TS]
01:12:10
◼
►
to do here has implications that ripple
[TS]
01:12:12
◼
►
down through history as we saw with the
[TS]
01:12:14
◼
►
HFS plus 1 after you make his decision
[TS]
01:12:15
◼
►
it's not easy to change it i suppose you
[TS]
01:12:19
◼
►
could go with case-sensitive now a new
[TS]
01:12:20
◼
►
case insensitive later but kinda like
[TS]
01:12:23
◼
►
the opposite of what HFS did going with
[TS]
01:12:24
◼
►
case-insensitive from the beginning and
[TS]
01:12:26
◼
►
making a sensitive variant but anyway
[TS]
01:12:28
◼
►
this I think is one of to me the most
[TS]
01:12:30
◼
►
important decisions that has not yet
[TS]
01:12:32
◼
►
been made for a PFS and I since it will
[TS]
01:12:36
◼
►
probably happen before next year's wrec
[TS]
01:12:38
◼
►
the only way we'll be able to tell
[TS]
01:12:39
◼
►
whether it's made is looking at the a
[TS]
01:12:42
◼
►
PFS documentation online and continuing
[TS]
01:12:44
◼
►
to run tiny test programs from languages
[TS]
01:12:46
◼
►
other than apples frameworks to see what
[TS]
01:12:48
◼
►
does the file system except I don't know
[TS]
01:12:51
◼
►
what the rights that this position I
[TS]
01:12:52
◼
►
don't have a particular position here
[TS]
01:12:53
◼
►
only I just want them to make a decision
[TS]
01:12:55
◼
►
and for it to be a reasonable one and
[TS]
01:12:59
◼
►
that's what I was about to ask is that
[TS]
01:13:00
◼
►
you don't necessarily have a preference
[TS]
01:13:04
◼
►
between normalised and not normalized
[TS]
01:13:06
◼
►
you just want to see that there is a a
[TS]
01:13:09
◼
►
declared statement as to how it's going
[TS]
01:13:11
◼
►
to work
[TS]
01:13:12
◼
►
yeah and like a philosophical some sort
[TS]
01:13:15
◼
►
of philosophical statement of support
[TS]
01:13:16
◼
►
because in many respects making the file
[TS]
01:13:19
◼
►
system itself just be bag of bytes which
[TS]
01:13:21
◼
►
is you gave me by store them is very
[TS]
01:13:23
◼
►
straightforward is the easiest to test
[TS]
01:13:25
◼
►
it is the simplest it's the fastest you
[TS]
01:13:29
◼
►
can do really fast comparisons with it
[TS]
01:13:31
◼
►
it's everything you want from a
[TS]
01:13:33
◼
►
performance perspective of all if you
[TS]
01:13:35
◼
►
were like say on the filesystem team and
[TS]
01:13:36
◼
►
you want to make it really fast file
[TS]
01:13:37
◼
►
system but from a user's perspective it
[TS]
01:13:39
◼
►
doesn't doesn't solve your problems it
[TS]
01:13:41
◼
►
doesn't solve user problems that hfs+
[TS]
01:13:44
◼
►
does i don't know if you can solve it
[TS]
01:13:47
◼
►
all at the framework level I'm have to
[TS]
01:13:50
◼
►
think that you can't really at the
[TS]
01:13:51
◼
►
framework level entirely because i don't
[TS]
01:13:55
◼
►
like there's so many different ways in
[TS]
01:13:56
◼
►
so many different programs that can
[TS]
01:13:58
◼
►
write files to disc and not all of them
[TS]
01:14:01
◼
►
go through your frameworks alright I in
[TS]
01:14:04
◼
►
its it's madness to have fought some
[TS]
01:14:07
◼
►
filenames utf-16 some vile names utf8
[TS]
01:14:09
◼
►
some normalized some did normalize some
[TS]
01:14:12
◼
►
weird mix I that seems untenable to me
[TS]
01:14:15
◼
►
from just the basic perspective of how
[TS]
01:14:17
◼
►
do i correctly check whether a file
[TS]
01:14:18
◼
►
exists the filename blah how do i check
[TS]
01:14:21
◼
►
whether that exists it's like well how
[TS]
01:14:23
◼
►
many different ways can you write this
[TS]
01:14:24
◼
►
kit you know the only way i can check
[TS]
01:14:27
◼
►
with this because the processing knows
[TS]
01:14:28
◼
►
nothing about encoding I say hey process
[TS]
01:14:29
◼
►
and you have a filename cafe and the
[TS]
01:14:32
◼
►
process was like all right well what
[TS]
01:14:33
◼
►
sequence of bytes you want me to check
[TS]
01:14:34
◼
►
for nope I don't have one that sequence
[TS]
01:14:36
◼
►
of bytes maybe think is there another
[TS]
01:14:38
◼
►
way that I cafe get right in utf-32 with
[TS]
01:14:41
◼
►
a combining accent you have this
[TS]
01:14:43
◼
►
sequence of bytes the files inside nope
[TS]
01:14:44
◼
►
don't have that sequence of bytes in the
[TS]
01:14:45
◼
►
applications like hmm maybe didn't
[TS]
01:14:47
◼
►
utf-16 with latin small letter with a
[TS]
01:14:49
◼
►
cute on it like that that's untenable
[TS]
01:14:51
◼
►
right and so as scary as it is for the
[TS]
01:14:53
◼
►
file system to make decisions about this
[TS]
01:14:55
◼
►
because they're just they're very
[TS]
01:14:57
◼
►
difficult to to change after the fact if
[TS]
01:14:59
◼
►
it doesn't then every file system API
[TS]
01:15:01
◼
►
needs to either be incredibly thorough
[TS]
01:15:04
◼
►
or put make it so that you can
[TS]
01:15:07
◼
►
potentially create files with apparently
[TS]
01:15:09
◼
►
the same name from the users perspective
[TS]
01:15:10
◼
►
and I think that's not healthy either so
[TS]
01:15:12
◼
►
I don't know it could be that we don't
[TS]
01:15:14
◼
►
care about any guys except for the cocoa
[TS]
01:15:16
◼
►
ones we don't care what people going
[TS]
01:15:17
◼
►
straight through the capi is running
[TS]
01:15:19
◼
►
python scripts or whatever we're doing
[TS]
01:15:20
◼
►
all we care about is that is the things
[TS]
01:15:22
◼
►
that go through
[TS]
01:15:24
◼
►
get and UI kit and then you could have a
[TS]
01:15:26
◼
►
bag of bytes
[TS]
01:15:27
◼
►
I don't know but but I i can hear
[TS]
01:15:30
◼
►
arguments on either side of it but the
[TS]
01:15:32
◼
►
fact that nothing has been said so far
[TS]
01:15:33
◼
►
in the fact that it just does Bagga
[TS]
01:15:35
◼
►
bites now doesn't really tell me
[TS]
01:15:36
◼
►
anything about that was essentially
[TS]
01:15:38
◼
►
position just tells me they didn't get
[TS]
01:15:39
◼
►
to that part yet because i think if they
[TS]
01:15:41
◼
►
if they had got to it would have been in
[TS]
01:15:43
◼
►
that presentation like the presentations
[TS]
01:15:44
◼
►
for developers to say
[TS]
01:15:46
◼
►
test your application on a PFS they did
[TS]
01:15:48
◼
►
tell them the tested based on the case
[TS]
01:15:50
◼
►
sensitive every part and that makes some
[TS]
01:15:52
◼
►
sense because that Apple has shipped the
[TS]
01:15:53
◼
►
case sensitive file system for a long
[TS]
01:15:54
◼
►
time and a lot of applications break
[TS]
01:15:57
◼
►
okay sensitive also seems like Adobe's
[TS]
01:15:58
◼
►
applications and Microsoft applications
[TS]
01:16:01
◼
►
all apps that were created in the days
[TS]
01:16:02
◼
►
before the mac even have a
[TS]
01:16:04
◼
►
case-sensitive filesystem many of them
[TS]
01:16:06
◼
►
believe not attempt to open files or
[TS]
01:16:08
◼
►
libraries and stuff by file paths that
[TS]
01:16:10
◼
►
do not match the case of the actual
[TS]
01:16:12
◼
►
files on disk you would think those have
[TS]
01:16:14
◼
►
bugs that woman takes long ago but the
[TS]
01:16:16
◼
►
bottom line is mac users don't run
[TS]
01:16:18
◼
►
case-sensitive file systems for the most
[TS]
01:16:19
◼
►
part i always luckily has always had
[TS]
01:16:21
◼
►
case-sensitive file systems but anyway
[TS]
01:16:22
◼
►
case-sensitive is separate from whether
[TS]
01:16:25
◼
►
things are normalized so I think if
[TS]
01:16:29
◼
►
Apple was committed to bag of bytes file
[TS]
01:16:31
◼
►
naming they would have maybe mention
[TS]
01:16:33
◼
►
that in the file system session but i'm
[TS]
01:16:35
◼
►
not sure
[TS]
01:16:36
◼
►
anyway it's it's a thing I think about a
[TS]
01:16:38
◼
►
lot and I have concerns our final
[TS]
01:16:41

◼
►
script I don't know if they can say that
[TS]
01:16:59
◼
►
but I can say that because I've used
[TS]
01:17:01
◼
►
many online backup programs and services
[TS]
01:17:03
◼
►
and back plays is by far the best one
[TS]
01:17:07
◼
►
that's worked out for me and my favorite

01:17:10
◼
►
before they were a sponsor
[TS]
01:17:11
◼
►
I have the backing up my computer to
[TS]
01:17:13
◼
►
computer even my mom's computer when
[TS]
01:17:15
◼
►
backing up something like six terabytes
[TS]
01:17:17
◼
►
of my data it is so solid it is
[TS]
01:17:21
◼
►
literally never causes a problem for for
[TS]
01:17:23
◼
►
the I don't know
[TS]
01:17:24
◼
►
45 years i've been using them highly

01:17:27
◼
►
recommend having online backup
[TS]
01:17:28
◼
►
especially to be playing around with the
[TS]
01:17:30
◼
►
file system on your computer you should
[TS]
01:17:33
◼
►
really have online backup to save your
[TS]
01:17:35
◼
►
butt if you do anything
[TS]
01:17:37
◼
►
good or if your local backups are all
[TS]
01:17:39
◼
►
corrupted by bit rock from hfs+ so check
[TS]
01:17:42
◼
►
out back plays today

◼
►
backblaze calm / ATP for that first for

download files as a big zip file you can
[TS]
01:17:57
◼
►
even have them overnight you a hard
[TS]
01:17:59
◼
►
drive with all your data if it's like a
[TS]
01:18:00
◼
►
ton of data and be taken to download and
[TS]
01:18:02
◼
►
if you return the hard drive back there
[TS]
01:18:05
◼
►
within 30 days you get a refund on the
[TS]
01:18:07
◼
►
price of the hard drive was a very
[TS]
01:18:08
◼
►
effective way to restore a ton of data
[TS]
01:18:10
◼
►
at once and not only that on the other
[TS]
01:18:12
◼
►
side if you want to restore one file you
[TS]
01:18:15
◼
►
can do it up in the web interface or
[TS]
01:18:17
◼
►
their iOS or android apps so one great
[TS]
01:18:20
◼
►
use for this is if you're on your phone
[TS]
01:18:21
◼
►
or let's say you're traveling only have
[TS]
01:18:23
◼
►
your laptop or something and you want to
[TS]
01:18:25
◼
►
file from your home computer you can do
[TS]
01:18:27
◼
►
this with back places back plays has all
[TS]
01:18:28
◼
►
your files it's just automatically
[TS]
01:18:30
◼
►
they're running back up everything you
[TS]
01:18:31
◼
►
don't have to think about it looks by
[TS]
01:18:33
◼
►
the way is how backup should work if you
[TS]
01:18:35
◼
►
think about it it's not really a backup
[TS]
01:18:36
◼
►
so exactly you can login to restore one
[TS]
01:18:39
◼
►
file if you look for a file on a trip or
[TS]
01:18:40
◼
►
something like that it is incredibly
[TS]
01:18:42
◼
►
community have done this probably five
[TS]
01:18:43
◼
►
or six times now because it's like it
[TS]
01:18:45
◼
►
it's just it doesn't happen often but
[TS]
01:18:47
◼
►
when it does happen i'm so glad i have
[TS]
01:18:49
◼
►
it and that's kind of the story of
[TS]
01:18:51
◼
►
online backup like you won't usually
[TS]
01:18:53
◼
►
need to use it but you'll be really glad
[TS]
01:18:55
◼
►
you've had it on those few times that
[TS]
01:18:57
◼
►
you do use it just five bucks a month
[TS]
01:18:59
◼
►
for unlimited space under throttled
[TS]
01:19:02
◼
►
speeds per computer so five bucks per
[TS]
01:19:04
◼
►
month per computer it is a great deal
[TS]
01:19:07
◼
►
unlimited space so check it out today go

01:19:14
◼
►
backpage.com / ATP thanks a lot
[TS]
01:19:20
◼
►
you guys have any opinions on before we
[TS]
01:19:23
◼
►
move not case sensitivity I so if for
[TS]
01:19:30
◼
►
that for the two questions that you've
[TS]
01:19:32
◼
►
basically posed here i think the file
[TS]
01:19:35
◼
►
system should you know on the topic of
[TS]
01:19:38
◼
►
like you know bag of bytes vs at least
[TS]
01:19:40
◼
►
normalizing you normally do some degree
[TS]
01:19:42
◼
►
weather you normalize for like unicode
[TS]
01:19:44
◼
►
normal forms for combining characters
[TS]
01:19:46
◼
►
and things or at least waited almost
[TS]
01:19:47
◼
►
four character encoding I think encoding
[TS]
01:19:50
◼
►
is an obvious when like you should
[TS]
01:19:53
◼
►
absolutely normalize for character
[TS]
01:19:55
◼
►
encoding you know and whatever including
[TS]
01:19:57
◼
►
the pic i I'm less concerned about that
[TS]
01:19:59
◼
►
you know if you pick utf-8 cool you know
[TS]
01:20:02
◼
►
I did whatever whatever including they
[TS]
01:20:03
◼
►
want to pick that's fine but i think it
[TS]
01:20:05
◼
►
is a clear win that the that the
[TS]
01:20:08
◼
►
encoding should be normalized for file
[TS]
01:20:10
◼
►
system access whether or not you know
[TS]
01:20:13
◼
►
normalizing forms of characters and case
[TS]
01:20:17
◼
►
sensitivity I mean that's kind of two
[TS]
01:20:19
◼
►
different degrees of the same kind of
[TS]
01:20:20
◼
►
thing that I i'm less confident on but
[TS]
01:20:25
◼
►
my inclination would be I think the era
[TS]
01:20:28
◼
►
of case in sensitivity is probably over
[TS]
01:20:32
◼
►
but I i would say that if I were
[TS]
01:20:35
◼
►
designing a system and having heard no
[TS]
01:20:37
◼
►
other arguments except for your ear for
[TS]
01:20:39
◼
►
your large amount of them i think the
[TS]
01:20:45
◼
►
cocoa api's should be responsible for
[TS]
01:20:48
◼
►
normalizing normal isn't the name like
[TS]
01:20:51
◼
►
you know case and and combining
[TS]
01:20:53
◼
►
characters why's that the low-level capi
[TS]
01:20:56
◼
►
eyes and and like that the the raw
[TS]
01:20:58
◼
►
interface with the file system should
[TS]
01:21:00
◼
►
not perform that kind of like messing
[TS]
01:21:02
◼
►
with characters for the filesystem throw
[TS]
01:21:04
◼
►
a fatal error if the if the encoding is
[TS]
01:21:07
◼
►
incorrect like if you give an invalid
[TS]
01:21:09
◼
►
utf-8 sequence is that just not work or
[TS]
01:21:11
◼
►
should i dutifully write those two discs
[TS]
01:21:13
◼
►
anyway yeah it's like if it doesn't do
[TS]
01:21:15
◼
►
that then you have the same problem
[TS]
01:21:16
◼
►
before like you can write a name and
[TS]
01:21:19
◼
►
then you go to you to read that name and
[TS]
01:21:21
◼
►
it's not there so I can see what i could
[TS]
01:21:23
◼
►
be a problem so maybe yes maybe the
[TS]
01:21:25
◼
►
answer is that if you try to have
[TS]
01:21:28
◼
►
involved you know sequence in the name
[TS]
01:21:30
◼
►
that you give it that maybe it does
[TS]
01:21:31
◼
►
error out
[TS]
01:21:31
◼
►
I don't know all rights because it's
[TS]
01:21:34
◼
►
basically quest
[TS]
01:21:34
◼
►
like suicide a pic utf-8 which is
[TS]
01:21:36
◼
►
actually a bit because that's what
[TS]
01:21:37
◼
►
everyone thinks because all the other
[TS]
01:21:38
◼
►
and coatings are stupid or not it may
[TS]
01:21:41
◼
►
pick that then they could just say oh
[TS]
01:21:44
◼
►
when you write your filename stay BFS
[TS]
01:21:47
◼
►
you should write them in utf-8 and then
[TS]
01:21:50
◼
►
if you don't do it like that's your own
[TS]
01:21:52
◼
►
stupid fault
[TS]
01:21:53
◼
►
in other words that they have it as a
[TS]
01:21:54
◼
►
policy not an implementation and
[TS]
01:21:57
◼
►
enforcement and so then later when some
[TS]
01:21:59
◼
►
other program tries to like in other
[TS]
01:22:01
◼
►
words you wrote it with an invalid utf-8
[TS]
01:22:02
◼
►
sequence and then later your program
[TS]
01:22:04
◼
►
tried to read it with that same invalid
[TS]
01:22:05
◼
►
utf-8 seconds it would find it right but
[TS]
01:22:07
◼
►
it would be garbage and then any other
[TS]
01:22:08
◼
►
any other API is trying to like compare
[TS]
01:22:11
◼
►
files or whatever would just you know
[TS]
01:22:13
◼
►
fail in weird ways because you have not
[TS]
01:22:15
◼
►
even written a value TFA sequence and
[TS]
01:22:17
◼
►
when it does it would like if you tried
[TS]
01:22:18
◼
►
to say is there a file called cafe it
[TS]
01:22:20
◼
►
would be like nope don't see it because
[TS]
01:22:22
◼
►
you just wrote invalid sequence the
[TS]
01:22:23
◼
►
other one is to have the the file system
[TS]
01:22:25
◼
►
in force at the you know that the driver
[TS]
01:22:28
◼
►
level and in all the various operating
[TS]
01:22:29
◼
►
systems if you pass some file name down
[TS]
01:22:32
◼
►
through the system down through the bsd
[TS]
01:22:33
◼
►
layers at some point we're gonna look
[TS]
01:22:35
◼
►
over your entire sequence and confirm is
[TS]
01:22:37
◼
►
this a valid utf-8 sequence and if it's
[TS]
01:22:39
◼
►
not boom everything blows up forget it
[TS]
01:22:41
◼
►
nothing works or you know whatever and i
[TS]
01:22:43
◼
►
don't know i think checking for that
[TS]
01:22:46
◼
►
checking the that its value tf8
[TS]
01:22:48
◼
►
shouldn't take long and should be fairly
[TS]
01:22:50
◼
►
straightforward because we're not
[TS]
01:22:51
◼
►
dealing with large drawings with data so
[TS]
01:22:53
◼
►
that's that that's what I think they
[TS]
01:22:54
◼
►
would go with they make that decision
[TS]
01:22:55
◼
►
that will essentially be impossible to
[TS]
01:22:57
◼
►
write an invalid utf-8 sequence to a
[TS]
01:23:00
◼
►
file name which could also break
[TS]
01:23:02
◼
►
applications like everything every
[TS]
01:23:03
◼
►
decision they make aside from make it
[TS]
01:23:05
◼
►
work exactly like hfs+ is gonna break
[TS]
01:23:06
◼
►
applications and make it work exactly
[TS]
01:23:08
◼
►
hfs+ is the one decision that i think is
[TS]
01:23:11
◼
►
entirely wrong
[TS]
01:23:12
◼
►
I mean how can this day and age you
[TS]
01:23:14
◼
►
wouldn't be unreasonable to have like an
[TS]
01:23:16
◼
►
actual intel hardware instruction to
[TS]
01:23:18
◼
►
validate his secrets of utf-8 character
[TS]
01:23:21
◼
►
yeah the rules aren't that complicated
[TS]
01:23:23
◼
►
like no you mean you don't even have you
[TS]
01:23:25
◼
►
don't have to save other where
[TS]
01:23:27
◼
►
corresponds to like a code defined code
[TS]
01:23:28
◼
►
pointing device and you can't and that's
[TS]
01:23:30
◼
►
more difficult to do certainly in
[TS]
01:23:32
◼
►
hardware not just like bit masking yeah
[TS]
01:23:34
◼
►
but anyway I'm I suspect that's probably
[TS]
01:23:37
◼
►
what they'll end up being the case
[TS]
01:23:38
◼
►
sensitivity i think it's still weird
[TS]
01:23:40
◼
►
issue because I think users of use of
[TS]
01:23:43
◼
►
computers even just on iOS where you're
[TS]
01:23:46
◼
►
not really ever pro
[TS]
01:23:47
◼
►
to write file name but certainly on the
[TS]
01:23:49
◼
►
mac having two files called like I don't
[TS]
01:23:53
◼
►
know like you know xmas and then you
[TS]
01:23:56
◼
►
write a file called xmas but you decide
[TS]
01:23:57
◼
►
to capitalize the X and you end up with
[TS]
01:23:58
◼
►
two files and you know you thought your
[TS]
01:24:00
◼
►
writing the previous one I don't know
[TS]
01:24:02
◼
►
they just case insensitivity i think is
[TS]
01:24:04
◼
►
more like how how regular people think
[TS]
01:24:06
◼
►
computer case sensitivity is a
[TS]
01:24:08
◼
►
programmers that computers work for sure
[TS]
01:24:09
◼
►
so I'm sure that it would be very
[TS]
01:24:12
◼
►
popular with programmers but I mean
[TS]
01:24:14
◼
►
maybe not because like i said the fact
[TS]
01:24:16
◼
►
that there are still mac applications
[TS]
01:24:17
◼
►
that only work on case-insensitive file
[TS]
01:24:19
◼
►
systems due to eminently fixable errors
[TS]
01:24:24
◼
►
in their source code it's like that's
[TS]
01:24:26
◼
►
never going to change unless you force
[TS]
01:24:27
◼
►
it to change
[TS]
01:24:28
◼
►
I don't know Casey have opinions yeah
[TS]
01:24:30
◼
►
you know I think that of all the places
[TS]
01:24:33
◼
►
you want to have the Wild West the file
[TS]
01:24:35
◼
►
system is not it and I think that
[TS]
01:24:38
◼
►
forcing an encoding makes sense i agree
[TS]
01:24:43
◼
►
with you
[TS]
01:24:44
◼
►
mostly that that users expect case
[TS]
01:24:49
◼
►
insensitivity but i don't know i think
[TS]
01:24:52
◼
►
what with the internet running on unix
[TS]
01:24:54
◼
►
for the most part in URLs generally
[TS]
01:24:56
◼
►
being case-sensitive I think that people
[TS]
01:24:58
◼
►
are starting to become more comfortable
[TS]
01:25:00
◼
►
with that
[TS]
01:25:01
◼
►
so if i had a vote I would say enforce
[TS]
01:25:06
◼
►
something like utf-8 if you write
[TS]
01:25:08
◼
►
something that's garbage or not utf-8
[TS]
01:25:11
◼
►
encoded barf all over it and then do so
[TS]
01:25:15
◼
►
violently and I would favor case
[TS]
01:25:17
◼
►
sensitivity by default
[TS]
01:25:19
◼
►
that's my vote I don't think anyone's in
[TS]
01:25:21
◼
►
favor of normalization but like i said
[TS]
01:25:23
◼
►
it you end up a weird situation so I
[TS]
01:25:24
◼
►
would if I was suspected they if they
[TS]
01:25:26
◼
►
don't touch normalization of the file
[TS]
01:25:28
◼
►
system level then they do it all the API
[TS]
01:25:30
◼
►
level but then it's just it's pretty
[TS]
01:25:32
◼
►
easy to make fairly absurd situations
[TS]
01:25:35
◼
►
for life but you could have picked some
[TS]
01:25:36
◼
►
word or phrase that has a huge number of
[TS]
01:25:40
◼
►
possible combinations like in some
[TS]
01:25:41

language of the uses accents on its
[TS]
01:25:43
◼

characters and just you know that the
[TS]
01:25:45
◼
►
number of possible permutations goes up
[TS]
01:25:48
◼
►
pretty quickly as you had the accented
[TS]
01:25:49
◼
►
characters then you make a folder full
[TS]
01:25:50
◼
►
of literally hundreds of files that all
[TS]
01:25:52
◼
►
appear to have exactly the same name in
[TS]
01:25:54
◼
►
the finder something you can't do hfs+
[TS]
01:25:56
◼

and something that you shouldn't be able
[TS]
01:26:00
◼
►
but we'll be able to do with the file
[TS]
01:26:02
◼
►
system even if it picking encoding but
[TS]
01:26:04
◼
►
they don't pick a normalization so
[TS]
01:26:05
◼
►
that's why I'm thinking about that's
[TS]
01:26:08
◼
►
because it's not it's not a
[TS]
01:26:09
◼
►
straightforward problem is not an
[TS]
01:26:10
◼
►
obvious answer that will clearly apple
[TS]
01:26:11
◼
►
will do this there is no easy answer
[TS]
01:26:13
◼
►
I never thought we talked this long
[TS]
01:26:15
◼
►
about the detailed implementation of
[TS]
01:26:18
◼
►
dealing with file names in the files as
[TS]
01:26:20
◼
►
well it's more just about unicode even
[TS]
01:26:22
◼
►
though right
[TS]
01:26:23
◼
►
you know you and I both know that having
[TS]
01:26:24
◼
►
dealt with it but i can tell you the
[TS]
01:26:26
◼
►
first five times I that with unicode I
[TS]
01:26:28
◼
►
still didn't understand only have a
[TS]
01:26:29
◼
►
six-time you know like it I if you have
[TS]
01:26:32
◼
►
never heard anything about unicode
[TS]
01:26:33
◼
►
hearing what i just said about all the
[TS]
01:26:35
◼
►
the code points normalization is not
[TS]
01:26:37
◼
►
going to sink in but it's it's weird and
[TS]
01:26:39
◼
►
if you don't know about it and think
[TS]
01:26:42
◼
►
about it when dealing with strings you
[TS]
01:26:44
◼
►
will eventually be sad no I mean dealing
[TS]
01:26:46
◼
►
with unicode in my experience is a lot
[TS]
01:26:48
◼
►
like parenting in that the more you
[TS]
01:26:52
◼
►
explore more experience you get in the
[TS]
01:26:55
◼
►
area the more you realize that you will
[TS]
01:26:57
◼
►
just always be wrong and there are no
[TS]
01:26:58
◼
►
good answers
[TS]
01:26:59
◼
►
Wow well I mean there's one thing is
[TS]
01:27:02
◼
►
just understanding the standards which i
[TS]
01:27:03
◼
►
think is difficult enough and then once
[TS]
01:27:04
◼
►
you understand the standards then you
[TS]
01:27:05
◼
►
realize no matter what I pick up there
[TS]
01:27:08
◼
►
are downsides and then then the real
[TS]
01:27:10
◼
►
said realization is that you realize all
[TS]
01:27:12
◼
►
the play if your program you realize all
[TS]
01:27:15
◼
►
the places in your program or Texas
[TS]
01:27:17
◼
►
coming in without the encoding specified
[TS]
01:27:19
◼
►
you're like I don't I don't even know
[TS]
01:27:20
◼
►
what the right thing to do is what who
[TS]
01:27:22
◼
►
how is this going to be encoded this is
[TS]
01:27:24
◼
►
just bites coming across some sort of
[TS]
01:27:25
◼
►
you know reading out of a disk file on
[TS]
01:27:28
◼
►
disk are coming across the network and
[TS]
01:27:30
◼
►
then you end up like dribbling out words
[TS]
01:27:31
◼
►
and asking all of your input sources hey
[TS]
01:27:33
◼
►
can you tell me what encoding using and
[TS]
01:27:35
◼
►
they say encoding what I didn't realize
[TS]
01:27:37
◼
►
you basically have an intractable
[TS]
01:27:39
◼
►
problem where it especially we are
[TS]
01:27:40
◼
►
accepting input from the wider world
[TS]
01:27:42
◼
►
that it doesn't come tagged along with
[TS]
01:27:45
◼
►
what encoding it is and you don't know
[TS]
01:27:47
◼
►
how to make sense of unless you know the
[TS]
01:27:48
◼
►
encoding so you kind of have to you can
[TS]
01:27:49
◼
►
detect the encoding through a bunch of
[TS]
01:27:51
◼
►
heuristics or i can guess or i can try
[TS]
01:27:53
◼
►
to enforce downstream that you should
[TS]
01:27:54
◼
►
only give it to me in this encoding and
[TS]
01:27:55
◼
►
then you find out how many people are
[TS]
01:27:57
◼
►
actually sending you things that don't
[TS]
01:27:59
◼
►
conform or all of a sudden you get a
[TS]
01:28:00
◼
►
bunch of utf-16 or shift just and you
[TS]
01:28:03
◼
►
have this terrible text terrible we
[TS]
01:28:05
◼
►
should communicate through a series of
[TS]
01:28:07
◼
►
ones and zeros it'd be much easier
[TS]
01:28:10
◼
►
wow I've never I've never heard shift
[TS]
01:28:14
◼
►
just discussing a podcast i don't think
[TS]
01:28:16
◼
►
i ever will again
[TS]
01:28:17
◼
►
oh yeah but my first big normalization
[TS]
01:28:19
◼
►
project was like what i would have
[TS]
01:28:21
◼
►
killed for utf-8 i think that's that's a
[TS]
01:28:24
◼
►
bet it was it before unicode thanks for
[TS]
01:28:26
◼
►
worse let's just put it that way
[TS]
01:28:27
◼
►
yeah no I mean it's not like I i'm
[TS]
01:28:29
◼
►
mostly avoided having to deal with these
[TS]
01:28:31
◼
►
issues over time with my various web
[TS]
01:28:33
◼
►
server because like you're right that
[TS]
01:28:34
◼
►
like hidden in native apps you don't
[TS]
01:28:37
◼
►
generally have to deal too much with
[TS]
01:28:38
◼
►
this on the web you deal with all the
[TS]
01:28:40
◼
►
time and the easiest thing on the web is
[TS]
01:28:43
◼
►
to just make all your pages serve utf-8
[TS]
01:28:45
◼
►
servicer themselves as utf-8 that may
[TS]
01:28:48
◼
►
call browser's default to sending utf-8
[TS]
01:28:50
◼
►
informs only the modern world will make
[TS]
01:28:53
◼
►
your browser's do that in the old world
[TS]
01:28:55
◼
►
you could do whatever you want with your
[TS]
01:28:56
◼
►
web pages but people in Japan we're
[TS]
01:28:58
◼
►
gonna be sending you things in a
[TS]
01:28:59
◼
►
different encoding and it doesn't matter
[TS]
01:29:01
◼
►
if you put a utf-8 is the you don't like
[TS]
01:29:03
◼
►
that was great when browser just finally
[TS]
01:29:05
◼
►
started to honor the encoding of the
[TS]
01:29:07
◼
►
yeah but that I mean that was most of my
[TS]
01:29:09
◼
►
career has been after that mean like
[TS]
01:29:10
◼
►
when we were building tumblr and 2006
[TS]
01:29:12
◼
►
that was the case so it's it's been ok
[TS]
01:29:14
◼
►
but and then the only the only time I
[TS]
01:29:17
◼
►
really had to think about unicode on on
[TS]
01:29:20
◼
►
web stuff recently is when emoji came
[TS]
01:29:23
◼
►
around and I had to alter all my mysql
[TS]
01:29:25
◼
►
tables to be the utf-8 mp4 character set
[TS]
01:29:29
◼
►
which is annoying but you know after
[TS]
01:29:31
◼
►
that it was a fine my single made some
[TS]
01:29:34
◼
►
some unicode mistakes that the best part
[TS]
01:29:36
◼
►
of the web and encoding is even coming
[TS]
01:29:40
◼
►
to the case sensitivity is that the old
[TS]
01:29:42
◼
►
URL that we increasingly don't see our
[TS]
01:29:44
◼
►
address bar the hostname part is not
[TS]
01:29:46
◼
►
case-sensitive whatever you think that
[TS]
01:29:48
◼
►
means the encoding for URLs yeah is i
[TS]
01:29:51
◼
►
think it is basically limited to ask you
[TS]
01:29:55
◼
►
but this way you can encode unicode code
[TS]
01:29:57
◼
►
points with the special escape sequence
[TS]
01:30:00
◼
►
II think not in the hostname there is in
[TS]
01:30:02
◼
►
the rest of the URL God knows what's
[TS]
01:30:04
◼
►
going on there in the honey there's a
[TS]
01:30:06
◼
►
special international demand extension
[TS]
01:30:08
◼
►
thing but that has a bunch of security
[TS]
01:30:10
◼
►
problems actually right of course and
[TS]
01:30:12
◼
►
then and then like you said for the rest
[TS]
01:30:13
◼
►
of the URL like it's it's kind of the
[TS]
01:30:16
◼
►
wild west and it's the worst that half
[TS]
01:30:17
◼
►
of the string is case sensitive and half
[TS]
01:30:19
◼
►
of it isn't again whatever the hell you
[TS]
01:30:22
◼
►
urls are still a problem that it in that
[TS]
01:30:26
◼
►
respect the body of your HTML documents
[TS]
01:30:28
◼
►
is is blessedly normalized at this point
[TS]
01:30:30
◼
►
because like you said most modern
[TS]
01:30:32
◼
►
browsers honor the encoding anyway Texas
[TS]
01:30:35
◼
►
alright well speaking of things that are
[TS]
01:30:39
◼
►
how about a data integrity yeah when
[TS]
01:30:42
◼
►
touching this last time this is the one
[TS]
01:30:44
◼
►
feature i wanted my BFS that it did not
[TS]
01:30:47
◼
►
deliver and we're speculating about why
[TS]
01:30:50
◼
►
that might be or if it really was the
[TS]
01:30:51
◼
►
case data integrity just the quick
[TS]
01:30:54
◼
►
review is basically the idea that if a
[TS]
01:30:57
◼
►
program writes some data to disk later
[TS]
01:31:01
◼
►
reads the data back the data that
[TS]
01:31:03
◼
►
originally wrote should be the data that
[TS]
01:31:04
◼
►
it gets back and that could be a day
[TS]
01:31:08
◼
►
later a year later ten years later if
[TS]
01:31:11
◼
►
that's not the case because hardware is
[TS]
01:31:12
◼
►
fallible you would like the file system
[TS]
01:31:15
◼
►
to know
[TS]
01:31:16
◼
►
hey you asked for these bites but it
[TS]
01:31:19
◼
►
turns out that since last time since
[TS]
01:31:21
◼
►
they were written they have been screwed
[TS]
01:31:23
◼
►
up so restore from backup or solve this
[TS]
01:31:27
◼
►
problem of ZFS and some other file
[TS]
01:31:29
◼
►
systems have a way to make multiple
[TS]
01:31:31
◼
►
redundant copies of the same data and
[TS]
01:31:33
◼
►
when they detect this area they can fix
[TS]
01:31:34
◼
►
it because they have a good copy bad
[TS]
01:31:37
◼
►
copy that will just ignore the bad copy
[TS]
01:31:39
◼
►
use the good copy and write another copy
[TS]
01:31:41
◼
►
of the good one or whatever all that
[TS]
01:31:44
◼
►
stuff is expensive because it means you
[TS]
01:31:45
◼
►
have to write out check someone's with
[TS]
01:31:46
◼
►
all of your data and you have to sort of
[TS]
01:31:48
◼
►
do end and check some so that everyone
[TS]
01:31:50
◼
►
is sure yet but i'm sending you this and
[TS]
01:31:52
◼
►
here's the checksum yep I got that and
[TS]
01:31:53
◼
►
here's the checksum alright disc making
[TS]
01:31:55
◼
►
sure everything is all good you know
[TS]
01:31:56
◼
►
that's what that's a feature of CFS is
[TS]
01:31:59
◼
►
very important and wonderful feature of
[TS]
01:32:01
◼
►
ZFS but it has a cost associated with it
[TS]
01:32:04
◼
►
both in terms of computation of
[TS]
01:32:05
◼
►
computing always check sums and also
[TS]
01:32:07
◼
►
dependency because you can't really be
[TS]
01:32:10
◼
►
done riding the data until you've also
[TS]
01:32:12
◼
►
made sure all the data was written
[TS]
01:32:13
◼
►
correctly and then also read written the
[TS]
01:32:15
◼
►
check so make sure that you know so
[TS]
01:32:16
◼
►
there's lots of dependencies that are
[TS]
01:32:18
◼
►
inherent in that and mostly I wanted it
[TS]
01:32:20
◼
►
for the the case of bit rod eyes and
[TS]
01:32:22
◼
►
over long periods of time I write out my
[TS]
01:32:24
◼
►
family's photos to disk and make backups
[TS]
01:32:27
◼
►
that disk that I push that up the back
[TS]
01:32:29
◼
►
plays and it's on time machine i'm doing
[TS]
01:32:31
◼
►
super duper clones and if some of those
[TS]
01:32:33
◼
►
bits are flipped because of
[TS]
01:32:34
◼
►
errors in the hardware all i'm doing is
[TS]
01:32:36
◼
►
copying those now corrupted bits over
[TS]
01:32:38
◼
►
and over and over again over the years
[TS]
01:32:40
◼
►
two different backups you know the
[TS]
01:32:42
◼
►
incremental backups don't go on forever
[TS]
01:32:43
◼
►
there's a window of time that you know
[TS]
01:32:44
◼
►
before they'll fit on the disc in the
[TS]
01:32:45
◼
►
same thing with backblaze they don't
[TS]
01:32:47
◼
►
think they keep your back forever and
[TS]
01:32:49
◼
►
ever and ever every different version so
[TS]
01:32:52
◼
►
eventually you will just have be
[TS]
01:32:54
◼
►
propagating the corruption over the
[TS]
01:32:55
◼
►
years until 20 years later we try to
[TS]
01:32:57
◼
►
look at some baby picture your favorite
[TS]
01:32:58
◼
►
baby picture is all messed up and all
[TS]
01:33:00
◼
►
scrambled and JP has a bunch of bits wet
[TS]
01:33:02
◼
►
and you don't know which ones
[TS]
01:33:03
◼
►
that's what I'm trying to protect
[TS]
01:33:04
◼
►
against and a PFS does not provide that
[TS]
01:33:08
◼
►
feature does not have the option to
[TS]
01:33:09
◼
►
write out checks comes with all of its
[TS]
01:33:11
◼
►
file data now a BFS is a flexible
[TS]
01:33:14
◼

filesystem intentionally designed to be
[TS]
01:33:15
◼
►
extensible without breaking backwards
[TS]
01:33:17
◼
►
compatibility
[TS]
01:33:18
◼
►
this feature can see would be added in
[TS]
01:33:21
◼
►
the future
[TS]
01:33:22
◼
►
hell it could be added before 2017 they
[TS]
01:33:24
◼
►
got a whole year right but it's not
[TS]
01:33:25
◼
►
there right now and that's a little bit
[TS]
01:33:27
◼
►
disappointing it does right check sums
[TS]
01:33:29
◼
►
for metadata metadata is like here's
[TS]
01:33:32
◼
►
what the files name is here's all the
[TS]
01:33:33
◼
►
dates the ownership the permissions and
[TS]
01:33:35
◼
►
here's where each individual piece of
[TS]
01:33:36
◼
►
this file data is on a disk so you know
[TS]
01:33:38
◼
►
where to go get it keeps saying desk but
[TS]
01:33:40
◼
►
you know that me and it writes checks on
[TS]
01:33:43
◼
►
this for metadata but I mean there's
[TS]
01:33:45
◼
►
good reason to do that mostly because a
[TS]
01:33:47
◼
►
lot of this file system like many others
[TS]
01:33:49
◼
►
tries to doesn't do always consistent on
[TS]
01:33:53
◼
►
disk representation but it comes close
[TS]
01:33:55
◼
►
it it wants to know did I finish this
[TS]
01:33:57
◼
►
operation so if someone yanked the plug
[TS]
01:33:59
◼
►
your computer and it was in the riddle
[TS]
01:34:00
◼
►
middle of writing a file what you want
[TS]
01:34:02
◼
►
to happen when you reboot is either the
[TS]
01:34:03
◼
►
entire files there are none of the files
[TS]
01:34:05
◼
►
there and check some metadata could
[TS]
01:34:08
◼
►
conceivably help with that because what
[TS]
01:34:10
◼
►
you're gonna do is you're gonna write
[TS]
01:34:12
◼
►
the data and write the metadata but the
[TS]
01:34:14
◼
►
debt metadata is not complete like it or
[TS]
01:34:16
◼
►
not we didn't finish if we're not done
[TS]
01:34:17
◼
►
then you just ignore all that it's all
[TS]
01:34:19
◼
►
invalid in the file basically isn't
[TS]
01:34:20
◼
►
there you have a consistent filesystem
[TS]
01:34:22
◼
►
don't worry about that partially written
[TS]
01:34:23
◼
►
file that partially written method or
[TS]
01:34:25
◼
►
whatever and how do you tell whether the
[TS]
01:34:27
◼
►
metadata is partially written while all
[TS]
01:34:28
◼
►
your metadata as check sums when you're
[TS]
01:34:30
◼
►
looking at that piece of metadata you
[TS]
01:34:32
◼
►
can look at it and do the checksum
[TS]
01:34:33
◼
►
inside is the checksum match the
[TS]
01:34:35
◼
►
metadata and if it does it's completed
[TS]
01:34:36
◼
►
if it doesn't you know you have a
[TS]
01:34:38
◼
►
journaling and stuff but the aps is not
[TS]
01:34:40
◼
►
used darling journaling is relatively
[TS]
01:34:42
◼
►
expensive way to do the same thing where
[TS]
01:34:43
◼
►
you sort of write out what you plan to
[TS]
01:34:45
◼
►
do then you do it and you write out that
[TS]
01:34:46
◼
►
you're done
[TS]
01:34:47
◼
►
and how it can tell whether you finish
[TS]
01:34:48
◼
►
the operation or not I metadata is in
[TS]
01:34:51
◼
►
general more important the data because
[TS]
01:34:53
◼
►
if you screw up the metadata you could
[TS]
01:34:54
◼
►
lose your entire disk like screwing up
[TS]
01:34:56
◼
►
the metadata for an entire directory and
[TS]
01:34:58
◼
►
then everything under it becomes
[TS]
01:34:59
◼
►
invisible whatever method is really
[TS]
01:35:01
◼
►
small and check sums are really fast on
[TS]
01:35:03
◼
►
it there's no real performance it so abs
[TS]
01:35:05
◼
►
does do check sums with metadata does
[TS]
01:35:07
◼
►
not do it with data this is a topic that
[TS]
01:35:10
◼
►
came up a lot of WC talking to other
[TS]
01:35:12
◼
►
people who had up the other file system
[TS]
01:35:15
◼
►
nerds who would also talked to people in
[TS]
01:35:17
◼
►
the possum team about a PFS and oh I
[TS]
01:35:21
◼
►
think I think this was a very popular
[TS]
01:35:26
◼
►
feature suggestion hey will be great if
[TS]
01:35:27
◼
►
API has had an interview or the question
[TS]
01:35:29
◼
►
why doesn't a PFS have data integrity
[TS]
01:35:31
◼
►
and a lot of the the reasons are you
[TS]
01:35:33
◼
►
know things that I said that is
[TS]
01:35:34
◼
►
potentially expensive one of the reasons
[TS]
01:35:37
◼
►
that I heard was that ssds do their own
[TS]
01:35:41
◼
►
check something internally which is true
[TS]
01:35:42
◼
►
they do because they have to deal with
[TS]
01:35:44
◼
►
the pretty startlingly unreliable nature
[TS]
01:35:48
◼
►
of flash storage you know all sort of
[TS]
01:35:52
◼
►
memory chips are inherently at the
[TS]
01:35:55
◼
►
bottom tiny little analog devices that
[TS]
01:35:57
◼
►
are a little bit scary when you find out
[TS]
01:35:58
◼
►
how they work and SSDs and are different
[TS]
01:36:01
◼
►
ssds have over-provisioning where they
[TS]
01:36:03
◼
►
have many more memory cells and they're
[TS]
01:36:05
◼
►
going to use and is actually a tiny
[TS]
01:36:06
◼
►
little operating system in there that's
[TS]
01:36:08
◼
►
trying to distribute all this stuff to
[TS]
01:36:09
◼
►
all the storage and they wear out if you
[TS]
01:36:11
◼
►
use them too much it's very very
[TS]
01:36:13
◼
►
complicated but they do copious not just
[TS]
01:36:15
◼
►
check sums but also error-correcting
[TS]
01:36:17
◼
►
code so if they find a bit flip because
[TS]
01:36:18
◼
►
of some analog or whatever they can fix
[TS]
01:36:20
◼
►
it before returning the data so that's
[TS]
01:36:23
◼
►
one of their stopgaps is like a spinning
[TS]
01:36:26
◼
►
this don't do that so much but they're
[TS]
01:36:27
◼
►
going out and ssds do the checksums
[TS]
01:36:29
◼
►
that's not really a great solution
[TS]
01:36:31
◼
►
because there are other places they're
[TS]
01:36:32
◼
►
convenient errors can be introduced like
[TS]
01:36:34
◼
►
in other hardware other than the SSD
[TS]
01:36:36
◼
►
itself like the bus and everything but
[TS]
01:36:38
◼
►
since Apple controls the entire chain
[TS]
01:36:40
◼
►
they control the bus that control the
[TS]
01:36:43
◼
►
ssds in theory especially as they make
[TS]
01:36:44
◼
►
max don't don't make max anymore that
[TS]
01:36:46
◼
►
you can swap lots of different hard
[TS]
01:36:48
◼
►
drives into and everything that they're
[TS]
01:36:50
◼
►
little bit better off the rails but
[TS]
01:36:51
◼
►
doesn't really help with bit rot right
[TS]
01:36:53
◼
►
all my family photos to one terabyte SSD
[TS]
01:36:55
◼
►
they get their successfully and then
[TS]
01:36:57
◼
►
five years later I have no idea if those
[TS]
01:36:59
◼
►
flip the file system can tell because it
[TS]
01:37:00
◼
►
doesn't know what it originally written
[TS]
01:37:01
◼
►
all I can really do is read them and say
[TS]
01:37:03
◼
►
here's what I've got on disk is that
[TS]
01:37:04
◼
►
what you wrote five years ago
[TS]
01:37:06
◼
►
beats the hell out of me i don't know so
[TS]
01:37:08
◼
►
I've been thinking about possible other
[TS]
01:37:10
◼
►
solutions of Apple never builds in data
[TS]
01:37:12
◼
►
integrity a PFS and one of them is
[TS]
01:37:14
◼
►
something that I think there's an hfs+
[TS]
01:37:17
◼
►
program does is ready
[TS]
01:37:18
◼
►
userspace solution II just scan all your
[TS]
01:37:21
◼
►
files checks on them write the check
[TS]
01:37:23
◼
►
from someplace else and then if anything
[TS]
01:37:26
◼
►
goes wrong with either the checksum or
[TS]
01:37:28
◼
►
the data itself the two won't match
[TS]
01:37:30
◼
►
anymore and you will know that your
[TS]
01:37:32
◼
►
files corrupted and you can restore from
[TS]
01:37:34
◼
►
backup so it's sort of like userspace
[TS]
01:37:36
◼
►
manual process of scanning all the files
[TS]
01:37:39
◼
►
that you care about and writing out the
[TS]
01:37:40
◼
►
check sums and periodically scanning
[TS]
01:37:42
◼
►
them all again and make sure the check
[TS]
01:37:43
◼
►
comes all matching about anything don't
[TS]
01:37:44
◼
►
match then restoring from your
[TS]
01:37:46
◼
►
presumably good backup you know so
[TS]
01:37:48
◼
►
basically in protecting instead wrought
[TS]
01:37:50
◼
►
by actively doing some process
[TS]
01:37:52
◼
►
periodically hoping that you don't
[TS]
01:37:53
◼
►
propagate whatever corruption has
[TS]
01:37:55
◼
►
appeared in to all of your incremental
[TS]
01:37:57
◼
►
backups you will know about the error in
[TS]
01:37:58
◼
►
enough time to restore from your backups
[TS]
01:38:00
◼
►
and that's kind of a heavyweight
[TS]
01:38:02
◼
►
solution think about the name of the HFS
[TS]
01:38:04
◼
►
plus program that does that clusters
[TS]
01:38:08
◼
►
maybe or maybe that's just the
[TS]
01:38:09
◼
►
impression anyway i'll try to look up
[TS]
01:38:11
◼
►
for the show notes the course if you if
[TS]
01:38:14
◼
►
you're a programmer and you think about
[TS]
01:38:16
◼
►
this problem for more than a few seconds
[TS]
01:38:17
◼
►
you realize that there is a big race
[TS]
01:38:20
◼
►
condition here where if you're trying to
[TS]
01:38:22
◼
►
read a file and check some it and then
[TS]
01:38:24
◼
►
write out that checksum what if between
[TS]
01:38:26
◼
►
the time that you read that file and the
[TS]
01:38:28
◼
►
time you wrote the check something
[TS]
01:38:30
◼
►
modified that file
[TS]
01:38:31
◼
►
what if it modified while you were in
[TS]
01:38:32
◼
►
the middle of reading it your your
[TS]
01:38:35
◼
►
checks on your file one match and it
[TS]
01:38:37
◼
►
will appear as if corruption occurred so
[TS]
01:38:39
◼
►
you can do a thing where you say okay
[TS]
01:38:40
◼
►
after I read the file
[TS]
01:38:42
◼
►
I can't calculate check something to
[TS]
01:38:43
◼
►
write the check some after at the
[TS]
01:38:45
◼
►
checksum I'll read the file again and if
[TS]
01:38:47
◼
►
it doesn't have to check some I won't
[TS]
01:38:49
◼
►
assume it's corrupt i'll just try to do
[TS]
01:38:50
◼
►
it again you just racing yourself over
[TS]
01:38:52
◼
►
and over again until you get a matching
[TS]
01:38:53
◼
►
set about how finally I got a matching
[TS]
01:38:55
◼
►
set but you're not solving the race
[TS]
01:38:57
◼
►
condition that way it's essentially a an
[TS]
01:39:00
◼
►
intractable race condition without help
[TS]
01:39:02
◼
►
from some other part of the system
[TS]
01:39:03
◼
►
without help for example a way to say i
[TS]
01:39:06
◼
►
want to stop anything else in the system
[TS]
01:39:08
◼
►
for writing to this file and in general
[TS]
01:39:10
◼
►
operating systems don't prove
[TS]
01:39:12
◼
►
I ways to do it provide advisory locking
[TS]
01:39:14
◼
►
but it's very difficult to stop anything
[TS]
01:39:17
◼
►
else from right into the system writing
[TS]
01:39:19
◼
►
to a particular file in general
[TS]
01:39:22
◼
►
luckily both hfs+ and I assume a PFS
[TS]
01:39:27
◼
►
include a feature that can help with
[TS]
01:39:29
◼
►
this I don't know why i was a tad hfs+
[TS]
01:39:31
◼
►
but it's been there for a couple years
[TS]
01:39:32
◼
►
now i think and it is what is it called
[TS]
01:39:36
◼
►
its called the the right generation
[TS]
01:39:38
◼
►
counter you can get this on any file
[TS]
01:39:40
◼
►
today on your mac and hfs+ of you all
[TS]
01:39:42
◼
►
get our list it's called the constant in
[TS]
01:39:44
◼
►
the ghetto ass man pages add our common
[TS]
01:39:47
◼
►
jen count it is a recording the
[TS]
01:39:50
◼
►
documentation nonzero monotonically
[TS]
01:39:52
◼
►
increasing generation count for this
[TS]
01:39:54
◼
►
file system objects for all classes and
[TS]
01:39:56
◼
►
objects not just files
[TS]
01:39:57
◼
►
it's basically a number that goes up
[TS]
01:39:58
◼
►
anytime anything happens to a file all
[TS]
01:40:00
◼
►
you gotta do is store both the checksum
[TS]
01:40:02
◼
►
and the generation count and then you
[TS]
01:40:06
◼
►
will know this checksum is for this
[TS]
01:40:07
◼
►
generation counter the file and if
[TS]
01:40:09
◼
►
anything in the entire system that
[TS]
01:40:10
◼
►
anything that file that number will go
[TS]
01:40:12
◼
►
up and you will know your checksum is
[TS]
01:40:13
◼
►
invalid so in the future when you're
[TS]
01:40:16
◼
►
checking for corruption you won't be
[TS]
01:40:17
◼
►
confused as I don't know I've detected
[TS]
01:40:18
◼
►
corruption because you will know that
[TS]
01:40:20
◼
►
yet the checksum doesn't match the file
[TS]
01:40:21
◼
►
data but that checksum was for
[TS]
01:40:23
◼
►
generation count number five and the
[TS]
01:40:25
◼
►
file is currently on generation account
[TS]
01:40:26
◼
►
number seven so it's time for Yuri
[TS]
01:40:28
◼
►
computer check some sodas a system
[TS]
01:40:30
◼
►
guaranteed way for you to match up the
[TS]
01:40:31
◼
►
checks on the generation count and the
[TS]
01:40:34
◼
►
content of the file and that is very
[TS]
01:40:36
◼
►
handy and it makes me think that cool
[TS]
01:40:39
◼
►
Marco here like i should write my first
[TS]
01:40:40
◼
►
mac program which is a file that just
[TS]
01:40:42
◼
►
does these checks out and use it because
[TS]
01:40:44
◼
►
I mean I'm gonna say i could write in
[TS]
01:40:46
◼
►
pearl but I totally could write in pearl
[TS]
01:40:47
◼
►
but now like an actual back from that
[TS]
01:40:49
◼
►
does this
[TS]
01:40:50
◼
►
it's really straightforward the only
[TS]
01:40:52
◼
►
real problem is where you write the
[TS]
01:40:53
◼
►
check sums you could write them to
[TS]
01:40:54
◼
►
extended attributes that seems kind of
[TS]
01:40:56
◼
►
antisocial to me you could write into a
[TS]
01:40:57
◼
►
separate database better be able to
[TS]
01:40:59
◼
►
handle millions of things but anyway i'm
[TS]
01:41:01
◼
►
actually thinking about this program a
[TS]
01:41:03
◼
►
simple program that you pointed a
[TS]
01:41:04
◼
►
subdirectory that doesn't check sums for
[TS]
01:41:06
◼
►
empirically scrubs it and tells you if
[TS]
01:41:08
◼
►
anything has a gun corrupt i think a
[TS]
01:41:11
◼
►
local sequel database would be a pretty
[TS]
01:41:13
◼
►
good way to do that you think that
[TS]
01:41:15
◼
►
because you have never inserted more
[TS]
01:41:16
◼
►
than a million rows in a sequel database
[TS]
01:41:18
◼
►
i have and i can tell you it falls over
[TS]
01:41:20
◼
►
badly and even likes a simple because I
[TS]
01:41:23
◼
►
would just be like you know a string key
[TS]
01:41:26
◼
►
knows how you represent the file name
[TS]
01:41:27
◼
►
but however you interpret the final
[TS]
01:41:29
◼
►
string key and check so you do the file
[TS]
01:41:33
◼
►
name but you can do that you have a
[TS]
01:41:35
◼
►
unique ID for the file with this another
[TS]
01:41:37
◼
►
thing you can get from hfs+ right so you
[TS]
01:41:39
◼
►
basically start like two integers
[TS]
01:41:41
◼
►
yeah it doesn't it doesn't do well try
[TS]
01:41:43
◼
►
if you try to do a graph like of
[TS]
01:41:44
◼
►
inserting maybe maybe I never tried with
[TS]
01:41:47
◼
►
parents have always had some string in
[TS]
01:41:49
◼
►
there but once you get into the millions
[TS]
01:41:51
◼
►
the insert start slowing way way way
[TS]
01:41:54
◼
►
down i know that i knows from experience
[TS]
01:41:56
◼
►
can you provide a custom value to be the
[TS]
01:41:58
◼
►
row ID how to get rid of the sequence ya
[TS]
01:42:01
◼
►
get rid of one integer if you can go if
[TS]
01:42:03
◼
►
you can provide a customer ID the new
[TS]
01:42:05
◼
►
then each Road only have effectively one
[TS]
01:42:08
◼
►
yeah I don't know why it's like maybe
[TS]
01:42:09
◼
►
it's a bit maybe I had indexes on it but
[TS]
01:42:11
◼
►
a ride I did it for like a data that was
[TS]
01:42:13
◼
►
like a couple of integers in a couple of
[TS]
01:42:14

strings and I left the you know that the
[TS]
01:42:16
◼
►
row ID and in the millions disaster
[TS]
01:42:20
◼
►
unmute becomes unusable like it's fine
[TS]
01:42:22
◼
►
in tens of thousands it's okay and
[TS]
01:42:24
◼
►
hundreds of thousands but once you get
[TS]
01:42:25
◼
►
into millions and this was maybe like
[TS]
01:42:27
◼
►
three years ago so many things are
[TS]
01:42:28
◼
►
improved but anyway there there are
[TS]
01:42:30
◼
►
solutions to this is not an
[TS]
01:42:31
◼
►
impossibility so I'm saying there's also
[TS]
01:42:33
◼
►
starting to peel is that will be fine
[TS]
01:42:34
◼
►
whatever it's worth I i'm pretty sure
[TS]
01:42:37
◼
►
there's some kind of optimization where
[TS]
01:42:38
◼
►
if you i think if you provide some kind
[TS]
01:42:41
◼
►
of like bigint column instead of the row
[TS]
01:42:44
◼
►
idea i think it will use that as the
[TS]
01:42:46
◼
►
right here so there's something like
[TS]
01:42:47
◼
►
that I I application be sure you know
[TS]
01:42:49
◼
►
there's a lot of innovation sequel I'd
[TS]
01:42:51
◼
►
you know it took to make it sort of less
[TS]
01:42:52
◼
►
safe but faster but you're doing an
[TS]
01:42:55
◼
►
extended attributes would be entirely
[TS]
01:42:56
◼
►
straightforward but i'm not sure that's
[TS]
01:42:58
◼
►
the best solution especially if you
[TS]
01:42:59
◼
►
don't have you have only read permission
[TS]
01:43:01
◼
►
to the files you can't write extended
[TS]
01:43:02
◼
►
attributes to them anyway have to think
[TS]
01:43:04
◼
►
about because extended at that address
[TS]
01:43:06
◼
►
is totally the way to do a file time
[TS]
01:43:08
◼
►
machine by the way does keep checksums
[TS]
01:43:10
◼
►
with all those files and has for many
[TS]
01:43:11
◼
►
years I forget where it stores and
[TS]
01:43:12
◼
►
probably an extended attributes but who
[TS]
01:43:14
◼
►
knows but anyway in time machine it owns
[TS]
01:43:16
◼
►
the entire area that it's writing too so
[TS]
01:43:19
◼
►
does not to worry about permissions
[TS]
01:43:20
◼
►
issues but anybody could be a limitation
[TS]
01:43:22
◼
►
of the program hey if it can't check
[TS]
01:43:24
◼
►
some a bunch of files always tell you
[TS]
01:43:25
◼
►
when it's done yeah you pointed me this
[TS]
01:43:27
◼
►
directory and it turns out they were you
[TS]
01:43:29
◼
►
know seven thousand files that i could
[TS]
01:43:31
◼
►
not check some because I can't write
[TS]
01:43:33
◼
►
them i don't know I've been thinking
[TS]
01:43:34
◼
►
about it a little bit is the world's
[TS]
01:43:35
◼
►
most boring program but
[TS]
01:43:37
◼
►
any absence of file systems support for
[TS]
01:43:39
◼
►
a bit rot detection we need some
[TS]
01:43:41
◼
►
solution and since it's technically
[TS]
01:43:43
◼
►
possible it's technically possible hfs+
[TS]
01:43:45
◼
►
was like i said this feature this
[TS]
01:43:46
◼
►
generation right counters is on hfs+ now
[TS]
01:43:48
◼
►
it's just that I've never really thought
[TS]
01:43:50
◼
►
about doing it as I was assumed the
[TS]
01:43:52
◼
►
filesystem come and save me but that
[TS]
01:43:53
◼
►
doesn't turn out to be the case I'm take
[TS]
01:43:55
◼
►
matters into my own hands
[TS]
01:43:56
◼
►
i mean if if there's ever like an app
[TS]
01:44:00
◼
►
that would be perfect for two days John
[TS]
01:44:02
◼
►
siracusa to make and publicize i mean i
[TS]
01:44:06
◼
►
can't i can't think of something that
[TS]
01:44:07
◼
►
would be better
[TS]
01:44:08
◼
►
yeah i mean the other solution as many
[TS]
01:44:09
◼
►
people tell you oh just make a use
[TS]
01:44:11
◼
►
freenas to make a ZFS mass and put all
[TS]
01:44:13
◼
►
your data on that and that would be a
[TS]
01:44:15
◼
►
solution that nobody wants to do that my
[TS]
01:44:17
◼
►
synology doesn't technology supports the
[TS]
01:44:19
◼
►
btrfs now which I think has day to check
[TS]
01:44:21
◼
►
something but my synology doesn't
[TS]
01:44:22
◼
►
support it so maybe when i went to Mass
[TS]
01:44:25
◼
►
eventually dies and are replaceable by
[TS]
01:44:26
◼
►
10 FS and that'll solve the problem but
[TS]
01:44:28
◼
►
in the meantime I'm experiment with this
[TS]
01:44:30
◼
►
sunday was the best thing is you'll get
[TS]
01:44:33
◼
►
Sherlock in like two years when they had
[TS]
01:44:34
◼
►
when they had exactly so the full
[TS]
01:44:36
◼
►
developer experience yeah exactly
[TS]
01:44:38
◼
►
because when i finally get it working
[TS]
01:44:40
◼
►
will be like now a PFS says the data
[TS]
01:44:42
◼
►
integrity get rejected from the mac app
[TS]
01:44:44
◼
►
store because it won't be sandbox about
[TS]
01:44:46
◼
►
all access yeah yeah yeahs try to sell
[TS]
01:44:51
◼
►
it get you know there will be something
[TS]
01:44:52
◼
►
like competitor that will sell theirs
[TS]
01:44:53
◼
►
for less than I like i said i think
[TS]
01:44:55
◼
►
there's already a program that does this
[TS]
01:44:56
◼
►
for each of us plus and presumably that
[TS]
01:44:58
◼
►
same program will work on a PM as I
[TS]
01:45:00
◼
►
forget the name of the programs but yeah
[TS]
01:45:01
◼
►
this is not it's not a new idea i think
[TS]
01:45:03
◼
►
this is already implemented an
[TS]
01:45:04
◼
►
application I just can't remember the
[TS]
01:45:06
◼
►
name which is probably why don't have it
[TS]
01:45:07
◼
►
installed for like no reason that when i
[TS]
01:45:09
◼
►
think about it like why haven't you done
[TS]
01:45:11
◼
►
this before why aren't you running the
[TS]
01:45:12
◼
►
HFS plus one that does this
[TS]
01:45:14
◼
►
I was always just thinking the sauces
[TS]
01:45:16
◼
►
that would save me I thought like well
[TS]
01:45:18
◼
►
I'll just I'll stick it out and nobody
[TS]
01:45:20
◼
►
knew file system here probably next year
[TS]
01:45:22
◼
►
and I've been thinking that for a lot of
[TS]
01:45:23
◼
►
years finally finally came
[TS]
01:45:26
◼
►
no data integrity alright what else is
[TS]
01:45:29
◼
►
going on me in apple filesystem tell me
[TS]
01:45:32
◼
►
about space sharing that this therefore
[TS]
01:45:34
◼
►
we gotta save that for a but i just want
[TS]
01:45:36
◼
►
to get dinner as well shuffled around
[TS]
01:45:37
◼
►
will save the other details to the rest
[TS]
01:45:39
◼
►
of this is the main point I want to get
[TS]
01:45:41
◼
►
to the word discuss will talk about
[TS]
01:45:42
◼
►
space sharing an atomic on snapshots

01:47:08
◼
►
that's pretty impressive really when you

01:47:14
◼
►
only one on apple buys what the hell's

◼
►
well then we will talk about it until
[TS]
01:47:25
◼

[TS]
01:47:29
◼
►
to be fair i have nothing else to talk
[TS]
01:47:31
◼
►
about so whatever I i discovered during
[TS]
01:47:35
◼
►
our show that you can not be theirs
[TS]
01:47:38
◼
►
I don't know when this became possible
[TS]
01:47:40
◼
►
but nailed on tap on the mac now
[TS]
01:47:43
◼
►
supports flagging where the flags can be
[TS]
01:47:46
◼
►
any color of this like list of multiple
[TS]
01:47:48
◼
►
colors and it's been that way for a
[TS]
01:47:49
◼
►
while I thought how long have i I've
[TS]
01:47:51
◼
►
always just hit you know command ship
[TS]
01:47:53
◼
►
lol whatever it is to set the flag I've
[TS]
01:47:55
◼
►
never known there were multiple flags
[TS]
01:47:58
◼
►
now I can make my crappy email filing
[TS]
01:48:00
◼
►
system even worse by making all like the
[TS]
01:48:02
◼
►
flag messages but i never get back to
[TS]
01:48:04
◼
►
now I can make them different colors i
[TS]
01:48:05
◼
►
never get back to and color your shame
[TS]
01:48:08
◼
►
yep wow you know if you never get back
[TS]
01:48:11
◼
►
to them maybe it's not worth flagging
[TS]
01:48:13
◼
►
yeah that's probably right now that
[TS]
01:48:15
◼
►
that's not that's not how that works its
[TS]
01:48:17
◼
►
flagging them because he thinks he has
[TS]
01:48:18
◼
►
to get back to them by saying because I
[TS]
01:48:20
◼
►
failed to they must not have been
[TS]
01:48:21
◼
►
important but it's not true
[TS]
01:48:23
◼
►
one could be like pick up adam from
[TS]
01:48:26
◼
►
daycare it's like well I never did it I
[TS]
01:48:27
◼
►
guess I was not important man flag
[TS]
01:48:30
◼
►
well the good thing is like it when when
[TS]
01:48:31
◼
►
you are as crappy and as slacking as i
[TS]
01:48:34
◼
►
am with was dealing with email and
[TS]
01:48:36
◼
►
responding to email most email removes
[TS]
01:48:40
◼
►
the need to respond to it if you just
[TS]
01:48:42
◼
►
don't do it for like two weeks
[TS]
01:48:44
◼
►
yeah but on the other hand i'm probably
[TS]
01:48:46
◼
►
losing a lot of friends and colleagues
[TS]
01:48:47
◼

by doing this so it's definitely not

Pakistan that before
[TS]
01:49:05
◼
►
no but it sounds like you guys have very
[TS]
01:49:07
◼
►
different systems i think it's worth
[TS]
01:49:09
◼
►
talking about assuming i have a system
[TS]
01:49:11
◼

could actually that's right this is all
[TS]
01:49:13
◼

this is a whole show i'm writing gonna
[TS]
01:49:14
◼

get my collection of hacks is not really
[TS]
01:49:16
◼
►
something i would describe as a system
[TS]
01:49:18
◼

it is it is more just like it just a
