0:00:02.960,0:00:06.560
far away in the heavenly abode of the

0:00:04.960,0:00:08.320
great god indra

0:00:06.560,0:00:10.160
there is a wonderful net which has been

0:00:08.320,0:00:12.080
hung by some cunning artificer

0:00:10.160,0:00:14.320
in such a manner that it stretches out

0:00:12.080,0:00:15.920
infinitely in all directions

0:00:14.320,0:00:18.240
in accordance with the extravagant

0:00:15.920,0:00:20.960
tastes of deities the artificer has hung

0:00:18.240,0:00:22.080
a single glittering jewel in each eye of

0:00:20.960,0:00:24.000
the net

0:00:22.080,0:00:26.480
and since the net itself is infinite the

0:00:24.000,0:00:28.400
jewels are infinite in number

0:00:26.480,0:00:30.480
there hang the jewels glittering like

0:00:28.400,0:00:33.440
stars in the first magnitude

0:00:30.480,0:00:34.800
a wonderful sight to behold were we to

0:00:33.440,0:00:35.680
select one of these jewels for

0:00:34.800,0:00:37.760
inspection

0:00:35.680,0:00:39.520
we would discover that in its polished

0:00:37.760,0:00:41.920
surface there are reflected

0:00:39.520,0:00:43.360
all the other jewels in the net infinite

0:00:41.920,0:00:45.600
in number

0:00:43.360,0:00:47.840
if we look still more closely we would

0:00:45.600,0:00:48.960
see that each of the jewels reflected in

0:00:47.840,0:00:52.239
this one jewel

0:00:48.960,0:00:54.000
reflects all the others this is the

0:00:52.239,0:00:56.840
metaphor of indra's net

0:00:54.000,0:00:59.359
which is told in some schools of

0:00:56.840,0:01:00.160
philosophy let's keep this metaphor in

0:00:59.359,0:01:01.920
mind

0:01:00.160,0:01:03.760
because it'll help us understand the

0:01:01.920,0:01:06.239
Emacs extension that we're about to

0:01:03.760,0:01:06.239
discuss

0:01:06.960,0:01:13.200
so in editing text there's two

0:01:10.080,0:01:16.880
main paradigms one

0:01:13.200,0:01:19.439
is um editing at the ground level

0:01:16.880,0:01:22.159
where the characters that we type

0:01:19.439,0:01:25.960
actually appear on the screen

0:01:22.159,0:01:28.479
the changes we make actually occur

0:01:25.960,0:01:30.720
[Music]

0:01:28.479,0:01:33.439
the other editing paradigm is where we

0:01:30.720,0:01:36.000
escape to a higher level

0:01:33.439,0:01:36.479
and now the characters that we type are

0:01:36.000,0:01:39.040
not

0:01:36.479,0:01:41.600
they don't actually appear on the screen

0:01:39.040,0:01:44.799
because we're not at the ground level

0:01:41.600,0:01:48.479
with the text we are at a higher level

0:01:44.799,0:01:51.920
looking down at the text

0:01:48.479,0:01:54.640
and regarding the text referring to

0:01:51.920,0:01:56.159
this world of text in terms of a

0:01:54.640,0:01:57.920
language

0:01:56.159,0:02:00.640
for instance we could describe this

0:01:57.920,0:02:02.079
world as having words and paragraphs and

0:02:00.640,0:02:04.640
sentences and

0:02:02.079,0:02:05.360
lines and so on and we could reason

0:02:04.640,0:02:08.800
about this

0:02:05.360,0:02:11.440
text in terms of these

0:02:08.800,0:02:13.120
textual entities and this textual

0:02:11.440,0:02:15.920
language

0:02:13.120,0:02:18.319
this is the second paradigm of text

0:02:15.920,0:02:18.319
editing

0:02:18.640,0:02:24.800
and when we're in the second paradigm

0:02:22.800,0:02:26.480
there is a way to go down to ground

0:02:24.800,0:02:28.160
level you hit enter

0:02:26.480,0:02:30.480
now or we'll hit enter to go down to the

0:02:28.160,0:02:33.200
ground level and you can hit escape

0:02:30.480,0:02:35.200
to go back out to the referential level

0:02:33.200,0:02:37.280
enter to go down to ground level

0:02:35.200,0:02:39.599
and escape to go up to the referential

0:02:37.280,0:02:39.599
level

0:02:40.160,0:02:48.239
now in vim the nouns

0:02:44.879,0:02:50.959
in this world of text all

0:02:48.239,0:02:51.519
share the same referential plane which

0:02:50.959,0:02:54.319
we call

0:02:51.519,0:02:54.959
normal mode so in normal mode all of the

0:02:54.319,0:02:57.360
nouns

0:02:54.959,0:02:58.959
of the world of text are available

0:02:57.360,0:03:00.959
whether it's words or sentences or

0:02:58.959,0:03:04.400
paragraphs

0:03:00.959,0:03:08.319
and they all share this same

0:03:04.400,0:03:11.120
referential plane and there's uh

0:03:08.319,0:03:12.720
they sort of compete for space on the

0:03:11.120,0:03:15.760
keyboard

0:03:12.720,0:03:17.680
um so an alternative uh

0:03:15.760,0:03:19.280
way to structure these modes is instead

0:03:17.680,0:03:21.840
of having a single mode where all the

0:03:19.280,0:03:24.959
nouns coexist

0:03:21.840,0:03:30.400
peacefully or otherwise you instead

0:03:24.959,0:03:33.040
have a dedicated mode for every noun

0:03:30.400,0:03:35.440
so in that case what happens is because

0:03:33.040,0:03:37.280
your modal spaces are now much smaller

0:03:35.440,0:03:38.720
you're just talking about words or

0:03:37.280,0:03:42.560
paragraphs or

0:03:38.720,0:03:45.760
lines or something the keys that you use

0:03:42.560,0:03:48.560
can be much more targeted

0:03:45.760,0:03:50.400
and you can use the same keystrokes in

0:03:48.560,0:03:52.000
in all of your modes and they would have

0:03:50.400,0:03:53.280
the same ideas behind them but

0:03:52.000,0:03:55.519
they would have different effects

0:03:53.280,0:03:57.519
depending on which context you're using

0:03:55.519,0:03:59.120
so it's the same keystrokes different

0:03:57.519,0:04:01.360
contexts

0:03:59.120,0:04:02.480
and the advantage of that is it's often

0:04:01.360,0:04:05.519
easier

0:04:02.480,0:04:09.040
to change context than it is to

0:04:05.519,0:04:12.080
learn new key bindings so let's see

0:04:09.040,0:04:13.680
an example of how that works we go into

0:04:12.080,0:04:14.000
character mode and if you look at the

0:04:13.680,0:04:15.439
mode

0:04:14.000,0:04:18.720
line at the bottom of the screen there

0:04:15.439,0:04:21.519
you'll see that we're in character mode

0:04:18.720,0:04:23.919
and now when we move up down left and

0:04:21.519,0:04:28.479
right we're moving by character

0:04:23.919,0:04:30.240
we can also transform the text and

0:04:28.479,0:04:32.400
the transformations occur in terms of

0:04:30.240,0:04:34.320
character

0:04:32.400,0:04:35.520
you can also go into word mode and in

0:04:34.320,0:04:38.560
word mode

0:04:35.520,0:04:40.000
the transformations that you do are on

0:04:38.560,0:04:42.320
words

0:04:40.000,0:04:43.440
and you try you your movement is also in

0:04:42.320,0:04:45.600
terms of words

0:04:43.440,0:04:46.560
so that's the level of granularity that

0:04:45.600,0:04:49.520
you have

0:04:46.560,0:04:50.720
you could also go to line mode and when

0:04:49.520,0:04:53.759
you're in line mode

0:04:50.720,0:04:54.240
you go up and down by line and you can

0:04:53.759,0:04:57.520
move

0:04:54.240,0:04:59.120
lines up and down left and right and so

0:04:57.520,0:05:00.880
on

0:04:59.120,0:05:02.800
and the transformations you do are in

0:05:00.880,0:05:07.600
terms of lines

0:05:02.800,0:05:07.600
you could also go to window mode where

0:05:08.400,0:05:12.400
now the objects that you're referring to

0:05:10.639,0:05:15.759
are windows and you can

0:05:12.400,0:05:17.520
move spatially amongst the windows or

0:05:15.759,0:05:20.850
make do transformations on the windows

0:05:17.520,0:05:22.840
using the same keystrokes

0:05:20.850,0:05:25.360
[Music]

0:05:22.840,0:05:28.720
um

0:05:25.360,0:05:32.800
so let's go to

0:05:28.720,0:05:35.280
um right and so um the one of the things

0:05:32.800,0:05:36.880
the the principles that play here is

0:05:35.280,0:05:38.000
something called the rumpelstiltskin

0:05:36.880,0:05:40.720
principle which is something

0:05:38.000,0:05:42.320
that's known in computer science which

0:05:40.720,0:05:43.759
is that if you can name something then

0:05:42.320,0:05:46.720
you have that you have power

0:05:43.759,0:05:48.560
then you have power over it so this is

0:05:46.720,0:05:50.479
kind of an adaptation of that principle

0:05:48.560,0:05:52.320
which says that if you can

0:05:50.479,0:05:54.000
name something and if you can talk about

0:05:52.320,0:05:55.360
it then it's a noun

0:05:54.000,0:05:56.960
[Music]

0:05:55.360,0:05:58.960
in your editing language and if it's a

0:05:56.960,0:06:01.520
noun then it has

0:05:58.960,0:06:02.319
it's a mode so if we can talk about it

0:06:01.520,0:06:05.039
it's a noun

0:06:02.319,0:06:06.479
if it's a noun then it's a mode and one

0:06:05.039,0:06:07.039
of the things we've been talking a lot

0:06:06.479,0:06:10.800
about

0:06:07.039,0:06:14.240
is modes so in fact

0:06:10.800,0:06:17.280
uh by this principle modes also

0:06:14.240,0:06:19.039
should be a mode

0:06:17.280,0:06:21.120
you should have a mode that can reason

0:06:19.039,0:06:22.080
in terms of modes as objects just like

0:06:21.120,0:06:23.759
you have

0:06:22.080,0:06:26.560
modes where you can reason in terms of

0:06:23.759,0:06:28.800
words or lines as objects

0:06:26.560,0:06:30.479
and so let's do that let's go to mode

0:06:28.800,0:06:34.000
mode

0:06:30.479,0:06:36.080
when you go to mode mode you see that uh

0:06:34.000,0:06:37.919
the objects that are depicted here are

0:06:36.080,0:06:40.960
the modes that are

0:06:37.919,0:06:44.880
that are present in the buffer

0:06:40.960,0:06:46.400
which we knew about um because the

0:06:44.880,0:06:48.720
style of editing that we had in this

0:06:46.400,0:06:50.479
buffer was the vim style of editing

0:06:48.720,0:06:52.400
where there's an insert mode at the

0:06:50.479,0:06:53.039
ground level and a normal mode that you

0:06:52.400,0:06:57.280
can escape

0:06:53.039,0:07:00.479
to you insert enter the ground level

0:06:57.280,0:07:02.880
enter to the insert mode and escape to

0:07:00.479,0:07:03.680
normal mode and when you look at the

0:07:02.880,0:07:06.160
mode mode

0:07:03.680,0:07:09.680
representation you see that in fact that

0:07:06.160,0:07:09.680
is the structure that's depicted

0:07:10.479,0:07:14.080
but in different situations you might

0:07:12.720,0:07:16.080
find

0:07:14.080,0:07:17.680
that you that these modes are not the

0:07:16.080,0:07:19.360
ones that you want you want something

0:07:17.680,0:07:20.880
more tailored for the specific

0:07:19.360,0:07:23.050
application

0:07:20.880,0:07:24.240
for instance if you're editing

0:07:23.050,0:07:27.360
[Music]

0:07:24.240,0:07:30.880
lisp code uh or or code in general but

0:07:27.360,0:07:32.960
list code is a particular example

0:07:30.880,0:07:34.000
you might want to take advantage of the

0:07:32.960,0:07:37.599
structure of

0:07:34.000,0:07:40.960
the code and for lisp code in particular

0:07:37.599,0:07:44.240
we have a mode called symax mode

0:07:40.960,0:07:46.720
which is able to reason

0:07:44.240,0:07:47.919
about your code in terms of its tree

0:07:46.720,0:07:50.560
structure

0:07:47.919,0:07:51.120
so you can use the same keystrokes hkl

0:07:50.560,0:07:53.440
goes

0:07:51.120,0:07:54.960
left right up and down but you also have

0:07:53.440,0:07:58.080
other keystrokes that are more

0:07:54.960,0:08:01.520
specialized to the application

0:07:58.080,0:08:06.160
and you can run the code and

0:08:01.520,0:08:06.160
we'll see that happen here in a minute

0:08:06.960,0:08:12.240
and you can make changes to it really

0:08:10.080,0:08:16.080
quickly

0:08:12.240,0:08:16.080
and see the effects of those changes

0:08:18.000,0:08:21.360
and you're doing this all in a mode

0:08:19.440,0:08:23.199
that's convenient for

0:08:21.360,0:08:25.039
this particular application which is

0:08:23.199,0:08:28.960
editing lisp code

0:08:25.039,0:08:31.039
and that is in this case symmex mode

0:08:28.960,0:08:32.640
so typically when you're editing code

0:08:31.039,0:08:34.800
like this you'd want to be

0:08:32.640,0:08:36.640
in insert mode actually typing out the

0:08:34.800,0:08:38.320
code

0:08:36.640,0:08:40.959
and then you'd want to escape to simex

0:08:38.320,0:08:42.159
mode rather than normal mode

0:08:40.959,0:08:44.080
and then you could escape again and

0:08:42.159,0:08:46.720
you'd end up in normal mode

0:08:44.080,0:08:48.000
so this if we go to mode mode we see is

0:08:46.720,0:08:51.040
depicted

0:08:48.000,0:08:52.800
as this tower where insert is at the

0:08:51.040,0:08:54.800
bottom and normal is at the top but

0:08:52.800,0:08:57.200
symmex mode is in between

0:08:54.800,0:08:58.800
the two you could also change that if

0:08:57.200,0:09:00.640
you like if you don't want cmx mode to

0:08:58.800,0:09:03.760
be there you could just

0:09:00.640,0:09:05.600
move it to the top and now you find some

0:09:03.760,0:09:06.160
mixes at the top and you enter down to

0:09:05.600,0:09:07.600
normal

0:09:06.160,0:09:10.480
you can see it on the status bar at the

0:09:07.600,0:09:13.839
bottom there enter to insert

0:09:10.480,0:09:16.480
escape to normal escape to symmex and

0:09:13.839,0:09:19.380
in fact you can even add more modes if

0:09:16.480,0:09:21.519
you don't like the existing ones

0:09:19.380,0:09:23.839
[Music]

0:09:21.519,0:09:25.440
and now we have an additional mode here

0:09:23.839,0:09:27.519
we have window mode it goes down to

0:09:25.440,0:09:30.320
symmex goes down to normal

0:09:27.519,0:09:33.600
enter the insert escape to normal escape

0:09:30.320,0:09:37.600
to smx escape the window

0:09:33.600,0:09:41.760
um so we've talked okay so another thing

0:09:37.600,0:09:45.360
actually to note here is that in editing

0:09:41.760,0:09:46.720
modes um

0:09:45.360,0:09:48.399
if you look at the mode line at the

0:09:46.720,0:09:50.640
bottom of the screen

0:09:48.399,0:09:51.519
you'll see that we are currently in this

0:09:50.640,0:09:54.560
buffer

0:09:51.519,0:09:57.600
we are currently in line mode

0:09:54.560,0:09:58.720
and I'm going to hit enter now and

0:09:57.600,0:10:01.519
you'll see that when I hit

0:09:58.720,0:10:02.160
enter nothing is happening it's still in

0:10:01.519,0:10:05.120
line mode

0:10:02.160,0:10:07.200
if you'd escape it's still in line mode

0:10:05.120,0:10:10.640
and you can find out the reason for that

0:10:07.200,0:10:12.800
by taking another meta jump out of this

0:10:10.640,0:10:15.279
and you'll see that in fact the reason

0:10:12.800,0:10:17.360
is that we're currently in line mode

0:10:15.279,0:10:19.519
and line mode is the only one available

0:10:17.360,0:10:21.760
in this tower

0:10:19.519,0:10:24.880
for editing the modes that are in

0:10:21.760,0:10:26.560
operation in your ground level

0:10:24.880,0:10:28.320
and in fact line mode is all you need

0:10:26.560,0:10:30.320
here because this is just

0:10:28.320,0:10:32.079
uh the nature of how these modes are

0:10:30.320,0:10:35.040
laid out is

0:10:32.079,0:10:36.399
in in rows and so line mode is the most

0:10:35.040,0:10:37.680
appropriate thing here

0:10:36.399,0:10:39.740
but you could change it to something

0:10:37.680,0:10:40.959
else if you like

0:10:39.740,0:10:44.160
[Music]

0:10:40.959,0:10:44.560
and then now we've seen two towers we've

0:10:44.160,0:10:48.079
seen

0:10:44.560,0:10:53.680
the vim tower and we've seen

0:10:48.079,0:10:56.959
also the symex tower the the lisp tower

0:10:53.680,0:10:58.880
and it turns out that because we've been

0:10:56.959,0:11:01.519
talking about towers now

0:10:58.880,0:11:02.800
by the rumpelstiltskin principle towers

0:11:01.519,0:11:06.399
also

0:11:02.800,0:11:09.279
um can be talked about

0:11:06.399,0:11:11.200
and therefore they also are a mode so

0:11:09.279,0:11:14.640
how do we go to tower mode

0:11:11.200,0:11:18.560
and the way we go tower mode is we do

0:11:14.640,0:11:18.560
we go in a slightly different direction

0:11:19.200,0:11:23.120
and we find that we are now in tower

0:11:20.800,0:11:23.120
mode

0:11:23.360,0:11:29.279
and we see that there are many towers

0:11:27.440,0:11:32.640
available so we're now

0:11:29.279,0:11:36.240
we're we're seeing several possible

0:11:32.640,0:11:39.120
towers that we have written

0:11:36.240,0:11:41.440
um to be available and for use in

0:11:39.120,0:11:44.000
different buffers and you can edit them

0:11:41.440,0:11:46.320
on the fly for instance let's enter this

0:11:44.000,0:11:46.320
tower

0:11:46.630,0:11:49.920
[Music]

0:11:48.000,0:11:51.519
and now you see that in the bottom of

0:11:49.920,0:11:52.480
the in the mode line you see that we're

0:11:51.519,0:11:54.240
going

0:11:52.480,0:11:56.480
across all of these different modes that

0:11:54.240,0:11:58.800
were in the tower

0:11:56.480,0:12:00.399
and you could escape and you could even

0:11:58.800,0:12:00.880
move things around you could put window

0:12:00.399,0:12:02.399
mode

0:12:00.880,0:12:04.079
all the way at the bottom right above

0:12:02.399,0:12:06.880
insert mode

0:12:04.079,0:12:09.839
let's see that happen there it is window

0:12:06.880,0:12:13.040
is right above insert

0:12:09.839,0:12:14.240
so on and the tower always reflects your

0:12:13.040,0:12:15.760
current position

0:12:14.240,0:12:17.600
so if you're in buffer mode here and you

0:12:15.760,0:12:19.120
go down to line mode

0:12:17.600,0:12:22.240
when you go back to mode mode you see

0:12:19.120,0:12:22.240
that we are in line mode

0:12:22.480,0:12:26.160
but in practice you wouldn't have a

0:12:24.000,0:12:28.959
tower this elaborate because

0:12:26.160,0:12:29.440
you'd rather have several smaller towers

0:12:28.959,0:12:33.360
you

0:12:29.440,0:12:36.639
enter that you alternate between

0:12:33.360,0:12:39.839
um okay so one

0:12:36.639,0:12:42.240
other thing of interest here is that

0:12:39.839,0:12:43.839
when you're in tower mode

0:12:42.240,0:12:45.920
if you look at the status line at the

0:12:43.839,0:12:49.200
bottom there we are currently

0:12:45.920,0:12:49.839
in buffer mode while we are in tower

0:12:49.200,0:12:51.600
mode

0:12:49.839,0:12:53.519
and tower mode actually isn't a mode

0:12:51.600,0:12:53.920
really neither is mode mode they're

0:12:53.519,0:12:58.000
really

0:12:53.920,0:13:00.959
referential planes or meta planes

0:12:58.000,0:13:03.120
um in any case you can see that we're in

0:13:00.959,0:13:04.560
buffer mode and we can take a meta jump

0:13:03.120,0:13:07.120
out of this to confirm

0:13:04.560,0:13:08.000
that buffer mode is the only mode

0:13:07.120,0:13:10.560
available

0:13:08.000,0:13:11.200
when we're editing towers because that's

0:13:10.560,0:13:14.240
the one

0:13:11.200,0:13:15.200
we need given that our towers are

0:13:14.240,0:13:21.839
represented

0:13:15.200,0:13:21.839
in individual buffers

0:13:23.200,0:13:26.320
right so let's uh let's see where we're

0:13:26.000,0:13:28.240
at

0:13:26.320,0:13:30.160
trump's still skin principle we talked

0:13:28.240,0:13:32.240
about mode mode

0:13:30.160,0:13:33.920
um we talked about the strange loop

0:13:32.240,0:13:37.820
application of

0:13:33.920,0:13:39.600
ground level modes in meta levels

0:13:37.820,0:13:42.240
[Music]

0:13:39.600,0:13:43.199
and yeah we saw the different towers and

0:13:42.240,0:13:46.639
in fact

0:13:43.199,0:13:49.839
you can we're currently in

0:13:46.639,0:13:49.839
vim tower

0:13:50.720,0:13:54.720
where you can go to Emacs tower and now

0:13:53.120,0:13:55.760
with a single keystroke you can

0:13:54.720,0:13:59.040
alternate

0:13:55.760,0:14:02.399
between e-max

0:13:59.040,0:14:05.519
and vim which are represented which are

0:14:02.399,0:14:07.839
modeled as towers

0:14:05.519,0:14:07.839
um

0:14:09.279,0:14:11.920
okay so

0:14:13.360,0:14:17.040
so there's uh the one thing that we've

0:14:15.360,0:14:18.160
sort of alluded to is that there are two

0:14:17.040,0:14:20.480
directions

0:14:18.160,0:14:22.399
that you can travel in when you're going

0:14:20.480,0:14:25.120
through this framework

0:14:22.399,0:14:32.560
one lev one direction is uh and we'll

0:14:25.120,0:14:32.560
visualize it with uh like so

0:14:33.760,0:14:37.040
there's two directions you can travel

0:14:35.120,0:14:38.399
and you can either go sideways or you

0:14:37.040,0:14:40.399
can go up and down

0:14:38.399,0:14:41.680
if you go sideways you're changing your

0:14:40.399,0:14:45.440
perspective

0:14:41.680,0:14:47.360
so normal mode word mode line mode

0:14:45.440,0:14:49.120
window mode and so on are all different

0:14:47.360,0:14:51.680
perspectives on your under on your

0:14:49.120,0:14:53.040
ground editing experience

0:14:51.680,0:14:55.519
and the other direction you can travel

0:14:53.040,0:14:57.920
in is up or down which takes you

0:14:55.519,0:14:59.600
through meta levels so you go from the

0:14:57.920,0:15:01.920
ground level editing experience

0:14:59.600,0:15:03.440
up to mode mode and then up to the tower

0:15:01.920,0:15:07.040
plane and so on

0:15:03.440,0:15:10.800
or uh yeah and so on

0:15:07.040,0:15:14.880
um yeah so this all sounds

0:15:10.800,0:15:18.160
very complex but the truth is

0:15:14.880,0:15:21.519
it's not really that complicated

0:15:18.160,0:15:22.959
even though it feels that way the reason

0:15:21.519,0:15:26.480
it isn't that complicated

0:15:22.959,0:15:28.800
is because no matter how many levels

0:15:26.480,0:15:30.160
up or down you go and no matter where

0:15:28.800,0:15:32.399
you are

0:15:30.160,0:15:34.079
whether you're in at the ground level

0:15:32.399,0:15:36.000
editing the actual text

0:15:34.079,0:15:37.600
or whether you're at a meta level some

0:15:36.000,0:15:39.279
unknown meta level and you don't know

0:15:37.600,0:15:42.320
where you are

0:15:39.279,0:15:44.399
no matter where you are the way in which

0:15:42.320,0:15:47.519
you interact with it

0:15:44.399,0:15:52.000
is the same at every level

0:15:47.519,0:15:55.440
and that is the great power of um

0:15:52.000,0:15:58.720
this approach is that

0:15:55.440,0:16:00.880
all of the different levels um are the

0:15:58.720,0:16:03.839
same

0:16:00.880,0:16:05.759
and in fact the complexity of the whole

0:16:03.839,0:16:08.720
is exactly identical to the

0:16:05.759,0:16:10.000
complexity of each part so if you know

0:16:08.720,0:16:12.959
how to edit words

0:16:10.000,0:16:13.440
in the ground level buffer and you know

0:16:12.959,0:16:15.839
how to move

0:16:13.440,0:16:16.720
lines around using line mode then you

0:16:15.839,0:16:19.519
know how to edit

0:16:16.720,0:16:22.800
any aspect of your editing experience at

0:16:19.519,0:16:23.310
any level

0:16:22.800,0:16:26.240
so

0:16:23.310,0:16:28.480
[Music]

0:16:26.240,0:16:28.480
um

0:16:30.079,0:16:33.839
so this is a pre-release demo this

0:16:32.000,0:16:36.880
doesn't exist on melpa

0:16:33.839,0:16:40.079
yet but you can follow updates um

0:16:36.880,0:16:44.079
at this repo on github

0:16:40.079,0:16:45.199
and if you can also be a beta tester or

0:16:44.079,0:16:46.000
something like that if you like that

0:16:45.199,0:16:49.199
would be very

0:16:46.000,0:16:50.560
uh helpful and you can learn more about

0:16:49.199,0:16:53.920
this at

0:16:50.560,0:16:55.920
dream.org which is where I house

0:16:53.920,0:16:57.279
the research that I work on and in

0:16:55.920,0:17:00.800
particular

0:16:57.279,0:17:03.600
the research on epistemic levels is what

0:17:00.800,0:17:06.480
inspired this particular Emacs extension

0:17:03.600,0:17:08.480
you can also learn about dialectical

0:17:06.480,0:17:10.880
inheritance attribution which is the

0:17:08.480,0:17:14.559
basis of

0:17:10.880,0:17:16.959
a new economic system that could be fair

0:17:14.559,0:17:19.439
and could lead to a prosperous and happy

0:17:16.959,0:17:22.799
world

0:17:19.439,0:17:26.319
and um yeah you can follow me on

0:17:22.799,0:17:31.919
twitter at countwajoula and

0:17:26.319,0:17:31.919
that's it thank you
