-you are now unmuted
-
-0:00:04.480,0:00:11.280
-okay can you guys hear me yeah
-
-0:00:08.000,0:00:14.480
-can you guys hear me sir yep I can and
-
-0:00:11.280,0:00:17.199
-we're live so take it away okay
-
-0:00:14.480,0:00:18.400
-so um hello everyone my name is ferming
-
-0:00:17.199,0:00:20.960
-I'm a programmer
-
-0:00:18.400,0:00:22.400
-a math student from spain I've been
-
-0:00:20.960,0:00:24.960
-using me e-max for
-
-0:00:22.400,0:00:26.000
-two years now more or less and today I'm
-
-0:00:24.960,0:00:28.320
-going to talk about
-
-0:00:26.000,0:00:29.199
-a maxima computer algebra system in 2
-
-0:00:28.320,0:00:32.239
-max
-
-0:00:29.199,0:00:34.239
-so let's talk about what is maxima
-
-0:00:32.239,0:00:36.079
-well maxim is a system for manipulation
-
-0:00:34.239,0:00:37.920
-of symbolic and numerical expression
-
-0:00:36.079,0:00:39.440
-and it's similar in some regard to
-
-0:00:37.920,0:00:42.160
-octave
-
-0:00:39.440,0:00:45.039
-and it's also free software is derived
-
-0:00:42.160,0:00:47.120
-from the maxima from the 60 from the m80
-
-0:00:45.039,0:00:48.320
-and it's written in common lisp which is
-
-0:00:47.120,0:00:50.719
-a language that I really
-
-0:00:48.320,0:00:51.600
-like I enjoy writing it so for me it's a
-
-0:00:50.719,0:00:55.039
-plus
-
-0:00:51.600,0:00:57.039
-okay so let's talk about the initial
-
-0:00:55.039,0:00:59.280
-support for maxima when I first started
-
-0:00:57.039,0:01:00.320
-using it I looked for support into Emacs
-
-0:00:59.280,0:01:03.120
-and I found that
-
-0:01:00.320,0:01:04.640
-there's two major modes in the main
-
-0:01:03.120,0:01:07.200
-repository of maxima
-
-0:01:04.640,0:01:09.280
-for remax the first one is imaxima which
-
-0:01:07.200,0:01:12.000
-I don't know too much about it
-
-0:01:09.280,0:01:13.439
-and the second one is maxima dot l which
-
-0:01:12.000,0:01:16.640
-is the one I took first
-
-0:01:13.439,0:01:18.080
-and it was pretty nice has like a major
-
-0:01:16.640,0:01:21.280
-mode a minor mode
-
-0:01:18.080,0:01:23.040
-a nice ripple but it also has some
-
-0:01:21.280,0:01:25.040
-disadvantage
-
-0:01:23.040,0:01:26.479
-and the first one is that is quite
-
-0:01:25.040,0:01:29.600
-outdated I think
-
-0:01:26.479,0:01:30.960
-it was from the 2007
-
-0:01:29.600,0:01:33.280
-so it's not tested with the current
-
-0:01:30.960,0:01:35.520
-email version and the second one
-
-0:01:33.280,0:01:36.320
-is that it doesn't use modern e-max
-
-0:01:35.520,0:01:38.640
-capability
-
-0:01:36.320,0:01:40.479
-I'm talking for example about the last
-
-0:01:38.640,0:01:44.720
-or more latex preview
-
-0:01:40.479,0:01:46.079
-from the last a max 27.1 I think
-
-0:01:44.720,0:01:47.920
-and that's why is that they know
-
-0:01:46.079,0:01:49.600
-integrated with common third party
-
-0:01:47.920,0:01:51.520
-extension I'm talking about company for
-
-0:01:49.600,0:01:55.360
-example third party
-
-0:01:51.520,0:01:57.280
-yeah you know the alpa melba packages
-
-0:01:55.360,0:01:58.719
-so uh this stock is going to be divided
-
-0:01:57.280,0:02:00.799
-in two parts the first one is going to
-
-0:01:58.719,0:02:03.040
-be how I maximize my date today
-
-0:02:00.799,0:02:03.840
-in max exercise don't worry it's going
-
-0:02:03.040,0:02:06.000
-to be
-
-0:02:03.840,0:02:07.680
-quite easy and the second one is going
-
-0:02:06.000,0:02:10.560
-to be why for the package
-
-0:02:07.680,0:02:13.200
-and the list improvement that I did and
-
-0:02:10.560,0:02:14.480
-a couple of things more maybe the future
-
-0:02:13.200,0:02:16.720
-and where's the package right now if you
-
-0:02:14.480,0:02:19.440
-can use it so
-
-0:02:16.720,0:02:21.360
-let's talk about the workflow so right
-
-0:02:19.440,0:02:23.040
-out of the box it has like an
-
-0:02:21.360,0:02:24.400
-orimal support I didn't write this it
-
-0:02:23.040,0:02:27.680
-was already
-
-0:02:24.400,0:02:30.319
-in Emacs
-
-0:02:27.680,0:02:32.720
-so that's pretty nice let's go with a
-
-0:02:30.319,0:02:34.480
-simple example
-
-0:02:32.720,0:02:36.000
-okay so this is an array of three
-
-0:02:34.480,0:02:37.920
-equations and three variables
-
-0:02:36.000,0:02:39.840
-so it's a system that can be solved and
-
-0:02:37.920,0:02:42.560
-the solution is unique
-
-0:02:39.840,0:02:44.120
-um so we're going to solve it right
-
-0:02:42.560,0:02:47.519
-let's go
-
-0:02:44.120,0:02:48.080
-solutions okay here's how you define a
-
-0:02:47.519,0:02:52.400
-variable
-
-0:02:48.080,0:02:52.400
-in it's called solve okay
-
-0:02:52.640,0:03:00.400
-it's called implicit explicit
-
-0:02:56.480,0:03:03.680
-sorry okay and now an array of
-
-0:03:00.400,0:03:05.760
-our variables actually okay
-
-0:03:03.680,0:03:07.599
-so first of all we have to send this
-
-0:03:05.760,0:03:10.400
-variable to the maxima
-
-0:03:07.599,0:03:11.200
-repo with we can do that with ctrl c
-
-0:03:10.400,0:03:14.480
-control c
-
-0:03:11.200,0:03:19.200
-or with the maxima send line
-
-0:03:14.480,0:03:20.560
-okay so let's um let's put the maxima
-
-0:03:19.200,0:03:23.680
-buffer right here
-
-0:03:20.560,0:03:25.360
-okay let's so um
-
-0:03:23.680,0:03:27.040
-right now we can get the solution like
-
-0:03:25.360,0:03:29.360
-this so we call already
-
-0:03:27.040,0:03:30.239
-uh we call this line right now control
-
-0:03:29.360,0:03:31.920
-sequence to c
-
-0:03:30.239,0:03:33.440
-as you can see we get like an array
-
-0:03:31.920,0:03:36.080
-inside an array because
-
-0:03:33.440,0:03:38.799
-uh let's see why we get this so we can
-
-0:03:36.080,0:03:42.239
-call maxima
-
-0:03:38.799,0:03:44.879
-help a point this will open a
-
-0:03:42.239,0:03:46.000
-dock um buffer with all information
-
-0:03:44.879,0:03:48.799
-about the
-
-0:03:46.000,0:03:51.360
-solve function so we can see that this
-
-0:03:48.799,0:03:54.560
-list of solution equations
-
-0:03:51.360,0:03:56.640
-you can see it okay so but we no we know
-
-0:03:54.560,0:03:58.239
-that this system only have one solution
-
-0:03:56.640,0:04:00.400
-so we're only interested in the first
-
-0:03:58.239,0:04:02.080
-one we can do this like pretty easily
-
-0:04:00.400,0:04:05.120
-just to take the first one
-
-0:04:02.080,0:04:06.640
-we can send it to the buffer so this is
-
-0:04:05.120,0:04:09.280
-quite easy example as you can see
-
-0:04:06.640,0:04:10.400
-they have to completion much of the help
-
-0:04:09.280,0:04:12.319
-facilities that we have
-
-0:04:10.400,0:04:14.720
-we can also get information about the
-
-0:04:12.319,0:04:17.440
-symbol for example maxima
-
-0:04:14.720,0:04:17.840
-symbol doc and we get in the and now you
-
-0:04:17.440,0:04:19.840
-can see
-
-0:04:17.840,0:04:20.959
-correctly in the mini buffer all the
-
-0:04:19.840,0:04:24.080
-possible
-
-0:04:20.959,0:04:28.000
-um parameter of the function
-
-0:04:24.080,0:04:31.440
-right so let's continue
-
-0:04:28.000,0:04:34.880
-okay so let's go to a more well
-
-0:04:31.440,0:04:38.560
-complicated example to say oops
-
-0:04:34.880,0:04:42.400
-okay so we have this
-
-0:04:38.560,0:04:43.919
-equation and we want to go from -1 to 5
-
-0:04:42.400,0:04:46.400
-I want to show in a nice
-
-0:04:43.919,0:04:47.759
-graph right first of all we begin
-
-0:04:46.400,0:04:51.759
-sending this line to the
-
-0:04:47.759,0:04:54.880
-maxima ripple hold it button again
-
-0:04:51.759,0:04:56.960
-okay um so this is not ideal if you want
-
-0:04:54.880,0:05:00.160
-to write down this equation because
-
-0:04:56.960,0:05:03.039
-it's quite messy what is when so
-
-0:05:00.160,0:05:04.479
-uh what's thing are where so we can call
-
-0:05:03.039,0:05:07.520
-the function maxima
-
-0:05:04.479,0:05:10.240
-let's say insert form okay
-
-0:05:07.520,0:05:11.280
-and this is more easy this basically put
-
-0:05:10.240,0:05:14.240
-text behind
-
-0:05:11.280,0:05:15.120
-and led or mode to render it and this is
-
-0:05:14.240,0:05:19.039
-quite easy to
-
-0:05:15.120,0:05:22.560
-write down you can use it like in every
-
-0:05:19.039,0:05:23.199
-expression so um first we have to call a
-
-0:05:22.560,0:05:27.280
-library
-
-0:05:23.199,0:05:29.199
-let's load the library library draw
-
-0:05:27.280,0:05:31.520
-we have also completion for local
-
-0:05:29.199,0:05:35.039
-variable and local
-
-0:05:31.520,0:05:38.240
-libraries sorry let me try to finish
-
-0:05:35.039,0:05:40.320
-draw okay and we send the line
-
-0:05:38.240,0:05:42.240
-so right now we have a leverage and we
-
-0:05:40.320,0:05:43.600
-should even have auto completion for the
-
-0:05:42.240,0:05:47.039
-library function
-
-0:05:43.600,0:05:50.400
-okay we have let's call draw2d
-
-0:05:47.039,0:05:51.199
-and now we can call implicit we should
-
-0:05:50.400,0:05:54.400
-have
-
-0:05:51.199,0:05:57.520
-okay and we can I mean put the variable
-
-0:05:54.400,0:05:58.639
-of equations we put the first variable d
-
-0:05:57.520,0:06:02.319
-minus
-
-0:05:58.639,0:06:05.280
-five d five five
-
-0:06:02.319,0:06:06.639
-the v variable the minus five and the
-
-0:06:05.280,0:06:09.680
-five
-
-0:06:06.639,0:06:11.759
-okay it should be all all good so let me
-
-0:06:09.680,0:06:14.639
-try to send it
-
-0:06:11.759,0:06:16.639
-okay you cannot see it right now because
-
-0:06:14.639,0:06:19.360
-I'm just sharing the maxima screen let
-
-0:06:16.639,0:06:23.520
-me try to change that
-
-0:06:19.360,0:06:27.199
-okay um
-
-0:06:23.520,0:06:27.199
-okay can you plot hello
-
-0:06:31.520,0:06:35.440
-okay so this is basically the graph that
-
-0:06:33.919,0:06:38.800
-I can upload generates
-
-0:06:35.440,0:06:41.039
-uh right now it's not integrated into
-
-0:06:38.800,0:06:42.240
-into the maximum package but it's a work
-
-0:06:41.039,0:06:46.000
-in progress
-
-0:06:42.240,0:06:50.160
-so let's go back to Emacs
-
-0:06:46.000,0:06:53.520
-uh where are you okay there you are okay
-
-0:06:50.160,0:06:56.639
-okay so um
-
-0:06:53.520,0:06:57.759
-let's continue so uh this is some of the
-
-0:06:56.639,0:07:00.000
-things that you can use
-
-0:06:57.759,0:07:01.919
-for your day-to-day programming in
-
-0:07:00.000,0:07:05.680
-maxima
-
-0:07:01.919,0:07:05.680
-let's go now with the
-
-0:07:05.759,0:07:08.880
-okay as you can see this is just text
-
-0:07:07.360,0:07:11.199
-that is render
-
-0:07:08.880,0:07:13.440
-okay let's go within a slide this is how
-
-0:07:11.199,0:07:14.400
-I use maxima a simple example you don't
-
-0:07:13.440,0:07:16.240
-want to
-
-0:07:14.400,0:07:17.919
-talk too much about it because everyone
-
-0:07:16.240,0:07:19.680
-use the package in a different way
-
-0:07:17.919,0:07:21.039
-so right now I'm going to talk about the
-
-0:07:19.680,0:07:23.520
-original package and
-
-0:07:21.039,0:07:25.120
-the way I change it right so the
-
-0:07:23.520,0:07:27.840
-documentation
-
-0:07:25.120,0:07:29.680
-of the original was great but for me it
-
-0:07:27.840,0:07:31.840
-wasn't embedded in the code
-
-0:07:29.680,0:07:33.599
-it was something sometimes hard to read
-
-0:07:31.840,0:07:36.319
-like it was like a big
-
-0:07:33.599,0:07:37.039
-chunk of comment it gave me all the
-
-0:07:36.319,0:07:40.400
-information
-
-0:07:37.039,0:07:44.240
-like um for me that's too much I prefer
-
-0:07:40.400,0:07:45.360
-a cohesive small comment and then a big
-
-0:07:44.240,0:07:47.759
-redmi will order
-
-0:07:45.360,0:07:48.960
-all the links and information so that's
-
-0:07:47.759,0:07:52.080
-one of the first thing I
-
-0:07:48.960,0:07:52.560
-change um then also completion I'm a big
-
-0:07:52.080,0:07:55.759
-fan
-
-0:07:52.560,0:07:58.639
-I'm used to slime so I'm I love
-
-0:07:55.759,0:08:00.160
-great auto completion so um the first
-
-0:07:58.639,0:08:01.840
-thing that I noticed that well
-
-0:08:00.160,0:08:04.479
-it uses an absolute function I don't
-
-0:08:01.840,0:08:07.039
-know if you can see correctly okay
-
-0:08:04.479,0:08:08.800
-comment dynamic is deprecated and it
-
-0:08:07.039,0:08:10.720
-also have like this
-
-0:08:08.800,0:08:12.720
-variable which is maximus symbol which
-
-0:08:10.720,0:08:16.160
-is basically a big
-
-0:08:12.720,0:08:19.280
-list of all the possible completions so
-
-0:08:16.160,0:08:20.960
-if I load the library it's not aware of
-
-0:08:19.280,0:08:23.039
-the new symbols or even if I
-
-0:08:20.960,0:08:24.240
-create a variable it's not loaded so
-
-0:08:23.039,0:08:26.160
-it's not dynamic
-
-0:08:24.240,0:08:28.319
-so I want the first thing I want is
-
-0:08:26.160,0:08:31.680
-dynamic completion right
-
-0:08:28.319,0:08:34.159
-so I improve it which wasn't that hard
-
-0:08:31.680,0:08:36.080
-I first of all create maximum completion
-
-0:08:34.159,0:08:38.479
-which we're going to see in a moment
-
-0:08:36.080,0:08:39.200
-and then it changes completion region so
-
-0:08:38.479,0:08:41.039
-this is the
-
-0:08:39.200,0:08:43.760
-improved version but the good thing is
-
-0:08:41.039,0:08:45.839
-like I decoupled the completion function
-
-0:08:43.760,0:08:47.600
-so I make that you can use it on your
-
-0:08:45.839,0:08:50.800
-own so you get a prefix
-
-0:08:47.600,0:08:52.560
-which is um like
-
-0:08:50.800,0:08:55.040
-the thing that you're going to also
-
-0:08:52.560,0:08:56.959
-complete you get the inferior process
-
-0:08:55.040,0:08:58.959
-which I'm going to talk about later but
-
-0:08:56.959,0:08:59.760
-basically it's a maxima process you can
-
-0:08:58.959,0:09:01.760
-work with
-
-0:08:59.760,0:09:03.040
-and you get an optional argument which
-
-0:09:01.760,0:09:06.399
-is fuzzy finding
-
-0:09:03.040,0:09:07.200
-okay so you can easily send a block here
-
-0:09:06.399,0:09:10.399
-what
-
-0:09:07.200,0:09:11.440
-uh with the propos which is a maxima
-
-0:09:10.399,0:09:13.839
-command that gets you
-
-0:09:11.440,0:09:14.959
-all the auto completion and then you
-
-0:09:13.839,0:09:18.240
-process the
-
-0:09:14.959,0:09:20.480
-the output and you return a list
-
-0:09:18.240,0:09:21.600
-of possible completion this function can
-
-0:09:20.480,0:09:24.800
-be easily put into
-
-0:09:21.600,0:09:26.640
-company as you can see you just
-
-0:09:24.800,0:09:28.560
-get maximum auxiliary inferior process
-
-0:09:26.640,0:09:32.080
-is a process that just
-
-0:09:28.560,0:09:35.360
-uses sorry I have of
-
-0:09:32.080,0:09:36.480
-all the apropos and the get that symbol
-
-0:09:35.360,0:09:39.440
-it's like uh
-
-0:09:36.480,0:09:41.360
-like you say auxiliary let's help me uh
-
-0:09:39.440,0:09:43.680
-for that dirty stuff
-
-0:09:41.360,0:09:44.640
-so and process manipulation let's talk
-
-0:09:43.680,0:09:46.959
-about
-
-0:09:44.640,0:09:47.920
-how the maxima process was in the
-
-0:09:46.959,0:09:50.720
-beginning
-
-0:09:47.920,0:09:52.560
-so at first it was just one process and
-
-0:09:50.720,0:09:54.560
-you send all of the things there
-
-0:09:52.560,0:09:56.320
-and you move the processor here and
-
-0:09:54.560,0:09:58.160
-there and
-
-0:09:56.320,0:09:59.600
-there was a global state right so all
-
-0:09:58.160,0:10:02.000
-the function depends on
-
-0:09:59.600,0:10:05.120
-variable global variables and I don't
-
-0:10:02.000,0:10:07.680
-like that approach I prefer more like a
-
-0:10:05.120,0:10:09.519
-shirt to say functional like you sense
-
-0:10:07.680,0:10:12.000
-one of things and you return
-
-0:10:09.519,0:10:13.440
-something so it's not like a void
-
-0:10:12.000,0:10:16.399
-function so to say
-
-0:10:13.440,0:10:18.079
-so I change it recipe uh well this is
-
-0:10:16.399,0:10:20.959
-the maxima start function now
-
-0:10:18.079,0:10:22.560
-let's just create a startup process with
-
-0:10:20.959,0:10:23.680
-this function which is maxima make
-
-0:10:22.560,0:10:26.880
-inferior
-
-0:10:23.680,0:10:30.000
-so this function just gets a name
-
-0:10:26.880,0:10:31.519
-and it return a process of maxima and
-
-0:10:30.000,0:10:32.240
-you can then manipulate it the way you
-
-0:10:31.519,0:10:35.600
-want
-
-0:10:32.240,0:10:36.800
-let's see a better version so this is
-
-0:10:35.600,0:10:39.200
-the opposite right this
-
-0:10:36.800,0:10:41.760
-remove an inferior process and delete
-
-0:10:39.200,0:10:43.440
-the process and kill the buffer
-
-0:10:41.760,0:10:45.519
-right so let's give an example because
-
-0:10:43.440,0:10:46.399
-this you can see pretty easily in this
-
-0:10:45.519,0:10:50.079
-example
-
-0:10:46.399,0:10:51.519
-so I want to go to the scratch buffer
-
-0:10:50.079,0:10:54.399
-which I think you can see it better
-
-0:10:51.519,0:10:55.760
-okay so this is the way you can get a
-
-0:10:54.399,0:10:58.320
-process with your name
-
-0:10:55.760,0:11:00.880
-and save it into a variable right let's
-
-0:10:58.320,0:11:02.880
-execute this so as you can see well
-
-0:11:00.880,0:11:03.920
-I don't know if you can see big you get
-
-0:11:02.880,0:11:05.839
-a process
-
-0:11:03.920,0:11:07.040
-let's go to it the process called my
-
-0:11:05.839,0:11:09.519
-maxima
-
-0:11:07.040,0:11:10.079
-as the buffer right and if we can you
-
-0:11:09.519,0:11:12.240
-can send
-
-0:11:10.079,0:11:14.959
-stuff to the process right we can call
-
-0:11:12.240,0:11:16.880
-maximus in block get a block of valid
-
-0:11:14.959,0:11:17.760
-maxima code and just pass the variable
-
-0:11:16.880,0:11:20.800
-the process
-
-0:11:17.760,0:11:21.519
-and we send code to the process right we
-
-0:11:20.800,0:11:23.440
-can
-
-0:11:21.519,0:11:25.760
-this is useful if you have some
-
-0:11:23.440,0:11:28.480
-expensive computation that you want
-
-0:11:25.760,0:11:29.680
-to process laser to say so the process
-
-0:11:28.480,0:11:32.640
-can manage it
-
-0:11:29.680,0:11:33.920
-and when you get the results correctly
-
-0:11:32.640,0:11:34.399
-you can also get the result from the
-
-0:11:33.920,0:11:35.920
-process
-
-0:11:34.399,0:11:38.000
-I mean I don't put it here but quite
-
-0:11:35.920,0:11:41.200
-easy and then you
-
-0:11:38.000,0:11:42.079
-removed in favor which is the way to get
-
-0:11:41.200,0:11:43.600
-rid of the process
-
-0:11:42.079,0:11:45.279
-and the buffer so if we call this
-
-0:11:43.600,0:11:48.399
-function we should get rid of the
-
-0:11:45.279,0:11:49.920
-this process and it works the processing
-
-0:11:48.399,0:11:54.160
-is no longer
-
-0:11:49.920,0:11:56.160
-I'm happy to continue so um
-
-0:11:54.160,0:11:57.680
-other things that improve the package on
-
-0:11:56.160,0:11:59.760
-my commitment during time
-
-0:11:57.680,0:12:01.360
-I'm going good okay another thing that I
-
-0:11:59.760,0:12:02.560
-did to the package was to add
-
-0:12:01.360,0:12:04.959
-continue integration and continue
-
-0:12:02.560,0:12:06.320
-delivery right so the package didn't
-
-0:12:04.959,0:12:09.440
-have any tests
-
-0:12:06.320,0:12:12.959
-and the code was a little bit messy so
-
-0:12:09.440,0:12:16.560
-I add integration a test
-
-0:12:12.959,0:12:19.519
-and test with the test simple framework
-
-0:12:16.560,0:12:20.560
-from rocky bursting the maintainer of
-
-0:12:19.519,0:12:23.279
-real
-
-0:12:20.560,0:12:24.079
-good which is a great package by the way
-
-0:12:23.279,0:12:25.920
-um
-
-0:12:24.079,0:12:28.079
-yeah this is one example of the process
-
-0:12:25.920,0:12:29.760
-so right now because um
-
-0:12:28.079,0:12:31.680
-the infrastructure of the process
-
-0:12:29.760,0:12:33.680
-management is decoupled
-
-0:12:31.680,0:12:35.200
-so I can test it pretty easily this is
-
-0:12:33.680,0:12:37.519
-the test function of the
-
-0:12:35.200,0:12:39.519
-inferior running so I can check if an
-
-0:12:37.519,0:12:41.440
-inferior is running right now
-
-0:12:39.519,0:12:43.200
-and I can just delete it after and get
-
-0:12:41.440,0:12:45.279
-the results
-
-0:12:43.200,0:12:46.959
-and I also did some integration with the
-
-0:12:45.279,0:12:48.639
-party packages the first one company of
-
-0:12:46.959,0:12:50.880
-course I love auto completion
-
-0:12:48.639,0:12:53.839
-the second one was hormone that was
-
-0:12:50.880,0:12:56.880
-already there and latex with the
-
-0:12:53.839,0:13:00.079
-um or logic insert form
-
-0:12:56.880,0:13:02.959
-and with poly mode because um let me
-
-0:13:00.079,0:13:03.680
-evaluate this maxima can understand lisp
-
-0:13:02.959,0:13:06.959
-code
-
-0:13:03.680,0:13:10.000
-well more or less it has like a
-
-0:13:06.959,0:13:11.279
-function so to say that you can send a
-
-0:13:10.000,0:13:13.600
-list command to the
-
-0:13:11.279,0:13:14.480
-maxima rebel and you can understand it
-
-0:13:13.600,0:13:17.839
-in some way so
-
-0:13:14.480,0:13:20.959
-we can go to the maxima poly
-
-0:13:17.839,0:13:22.800
-only maxima right you enable polymaxima
-
-0:13:20.959,0:13:25.519
-and it creates a polymode
-
-0:13:22.800,0:13:26.399
-which this is lisp code and this is
-
-0:13:25.519,0:13:28.639
-maxima code
-
-0:13:26.399,0:13:30.560
-so we can send this to the maxima ripple
-
-0:13:28.639,0:13:34.240
-we come to c control r which
-
-0:13:30.560,0:13:37.760
-it sends the um the current
-
-0:13:34.240,0:13:40.160
-um area region sorry
-
-0:13:37.760,0:13:41.839
-and we define a variable which is called
-
-0:13:40.160,0:13:44.000
-test and as we can see we have the
-
-0:13:41.839,0:13:47.360
-variable test right here so you can
-
-0:13:44.000,0:13:48.079
-program in lisp and you can send it to
-
-0:13:47.360,0:13:50.399
-maxima
-
-0:13:48.079,0:13:51.920
-so this is pretty good pretty nice um
-
-0:13:50.399,0:13:55.040
-working integration with
-
-0:13:51.920,0:13:57.120
-the slime mode and with swank so you can
-
-0:13:55.040,0:13:59.120
-actually have a completion of
-
-0:13:57.120,0:14:00.959
-a function inside the maximal list
-
-0:13:59.120,0:14:02.800
-package but
-
-0:14:00.959,0:14:04.399
-this is going to take quite a while
-
-0:14:02.800,0:14:07.360
-because it's not trivial
-
-0:14:04.399,0:14:09.440
-so um we're the feature of maxima right
-
-0:14:07.360,0:14:11.519
-now well we have fonts highlighting
-
-0:14:09.440,0:14:14.480
-smart indentation uh it was already in
-
-0:14:11.519,0:14:16.880
-the package but now it's quite better
-
-0:14:14.480,0:14:18.160
-great help functions right now I can
-
-0:14:16.880,0:14:20.800
-find the recommendation quite
-
-0:14:18.160,0:14:22.160
-fast and currently the menu integration
-
-0:14:20.800,0:14:23.120
-this is quite basic it needs to be a
-
-0:14:22.160,0:14:25.199
-little bit improved
-
-0:14:23.120,0:14:26.720
-uh latex support also completion the
-
-0:14:25.199,0:14:28.480
-company and maximizer process
-
-0:14:26.720,0:14:29.120
-integration and mini buffer I didn't
-
-0:14:28.480,0:14:32.880
-show you
-
-0:14:29.120,0:14:34.639
-but basically if you call global maxima
-
-0:14:32.880,0:14:36.720
-minor mode you have the minor mode you
-
-0:14:34.639,0:14:38.399
-call maxima mini buffer
-
-0:14:36.720,0:14:40.720
-how are you okay mini buffer you can
-
-0:14:38.399,0:14:42.720
-basically just write simple maxima
-
-0:14:40.720,0:14:45.920
-command and it will give you the result
-
-0:14:42.720,0:14:48.959
-this is like a permanent version of um
-
-0:14:45.920,0:14:50.560
-calc so you can do it you write the
-
-0:14:48.959,0:14:52.320
-command and you get the output uh way
-
-0:14:50.560,0:14:56.079
-more to come I have like a list
-
-0:14:52.320,0:14:58.880
-of issues that I put enhancement a new
-
-0:14:56.079,0:15:01.199
-feature that I'm going to develop
-
-0:14:58.880,0:15:03.120
-so uh the future under presence of the
-
-0:15:01.199,0:15:06.880
-package well the package is right now
-
-0:15:03.120,0:15:10.720
-melpa a melba stable um
-
-0:15:06.880,0:15:13.360
-in this 0.7.6 version
-
-0:15:10.720,0:15:15.279
-and I'm planning to include into the
-
-0:15:13.360,0:15:16.720
-known canoe alpha
-
-0:15:15.279,0:15:18.959
-this is the url of the package by the
-
-0:15:16.720,0:15:20.079
-way so you can if you go to metapod you
-
-0:15:18.959,0:15:22.160
-put maxima and
-
-0:15:20.079,0:15:23.199
-you can download it it doesn't have too
-
-0:15:22.160,0:15:26.639
-much dependencies
-
-0:15:23.199,0:15:27.120
-you aware of that um and thank you very
-
-0:15:26.639,0:15:28.720
-much
-
-0:15:27.120,0:15:30.959
-uh this is going to be my talk these are
-
-0:15:28.720,0:15:33.519
-my uh information

-0:15:55.759,0:16:01.759
-uh yeah I'm reading like this um
-
-0:15:58.800,0:16:04.079
-so I'm a buddy october usually right now
-
-0:16:01.759,0:16:04.079
-okay
-
-0:16:04.560,0:16:08.639
-maxima over october yep there are a
-
-0:16:06.880,0:16:11.519
-couple questions
-
-0:16:08.639,0:16:12.160
-wow maxima we're okay I don't want to I
-
-0:16:11.519,0:16:13.940
-don't know
-
-0:16:12.160,0:16:15.680
-october that much um
-
-0:16:13.940,0:16:17.839
-[Music]
-
-0:16:15.680,0:16:18.880
-like I use it like a couple of times but
-
-0:16:17.839,0:16:24.000
-I'm not happy
-
-0:16:18.880,0:16:27.120
-and I found the octave packets to be
-
-0:16:24.000,0:16:31.519
-quite a little bit harder to understand
-
-0:16:27.120,0:16:33.839
-and also that
-
-0:16:31.519,0:16:35.680
-it didn't have too much features like I
-
-0:16:33.839,0:16:37.839
-prefer the maximum used to
-
-0:16:35.680,0:16:38.880
-maybe octave is better I don't I'm not
-
-0:16:37.839,0:16:40.800
-100 sure
-
-0:16:38.880,0:16:42.079
-I know that you can use it for similar
-
-0:16:40.800,0:16:45.920
-stuff but
-
-0:16:42.079,0:16:45.920
-that's it so sorry
-
-0:16:47.120,0:16:54.079
-okay I'm in a little bit of a rush sorry
-
-0:16:50.959,0:16:56.399
-let me drink a little blue okay
-
-0:16:54.079,0:16:56.399
-okay
-
-0:17:00.639,0:17:08.000
-okay how does maxima compare to sagemath
-
-0:17:05.280,0:17:08.000
-in imax
-
-0:17:08.959,0:17:17.439
-I mean I don't know what is sage
-
-0:17:13.360,0:17:18.079
-math I'm sorry um so I cannot answer
-
-0:17:17.439,0:17:21.839
-your question
-
-0:17:18.079,0:17:25.039
-with your question I think um
-
-0:17:21.839,0:17:26.720
-sorry but I mean maxima is ready in
-
-0:17:25.039,0:17:28.000
-combo list that's just a preference for
-
-0:17:26.720,0:17:31.120
-me because I like
-
-0:17:28.000,0:17:35.520
-lisp dialect and common lisp is
-
-0:17:31.120,0:17:35.520
-interesting um
-
-0:17:36.400,0:17:42.720
-yeah do you plan to
-
-0:17:40.480,0:17:43.840
-I mean a maximum organization for maxima
-
-0:17:42.720,0:17:47.360
-code block
-
-0:17:43.840,0:17:50.720
-yes I want to improve the um
-
-0:17:47.360,0:17:52.000
-of maxima package but I didn't have
-
-0:17:50.720,0:17:54.400
-enough time and I want to
-
-0:17:52.000,0:17:57.200
-clear a little bit of the code because
-
-0:17:54.400,0:17:57.200
-still right now
-
-0:17:58.000,0:18:02.080
-the code is quite messy in some areas
-
-0:18:00.080,0:18:03.520
-because I pretty much implement first
-
-0:18:02.080,0:18:05.600
-the base function I want to
-
-0:18:03.520,0:18:07.120
-build on top of so right now it's quite
-
-0:18:05.600,0:18:07.919
-usable but I still have something that I
-
-0:18:07.120,0:18:11.120
-want to improve
-
-0:18:07.919,0:18:14.799
-so when I finish that I will
-
-0:18:11.120,0:18:16.640
-improve the normal version I think
-
-0:18:14.799,0:18:18.640
-it's maximizing to get into into your
-
-0:18:16.640,0:18:21.200
-opinion yes I
-
-0:18:18.640,0:18:21.919
-I think that the creator of maxima like
-
-0:18:21.200,0:18:26.400
-have this
-
-0:18:21.919,0:18:26.400
-lisp mine and probably
-
-0:18:26.640,0:18:30.559
-that they if you go to a symbol you get
-
-0:18:29.520,0:18:33.520
-all the information
-
-0:18:30.559,0:18:36.480
-and that reflects that you can actually
-
-0:18:33.520,0:18:40.000
-write your program of maxima into
-
-0:18:36.480,0:18:40.799
-um into lisp literally because they have
-
-0:18:40.000,0:18:42.480
-a command
-
-0:18:40.799,0:18:44.880
-so I think that is quite easy to get
-
-0:18:42.480,0:18:48.240
-into some university use it for
-
-0:18:44.880,0:18:51.200
-um first um
-
-0:18:48.240,0:18:53.039
-years so it's quite easy and I think
-
-0:18:51.200,0:18:56.640
-with my package you can use it
-
-0:18:53.039,0:18:58.960
-like pretty pretty easily just create a
-
-0:18:56.640,0:19:00.880
-file and you can start typing and
-
-0:18:58.960,0:19:04.400
-maximize quite easy to install also
-
-0:19:00.880,0:19:07.600
-so I think yeah it's crazy and
-
-0:19:04.400,0:19:10.080
-the page should restart I don't know why
-
-0:19:07.600,0:19:10.080
-sorry
-
-0:19:18.320,0:19:25.440
-strict in fixed lisp syntax
-
-0:19:22.559,0:19:26.240
-you're talking about the maxima itself
-
-0:19:25.440,0:19:27.760
-syntax
-
-0:19:26.240,0:19:30.160
-or I don't understand the question
-
-0:19:27.760,0:19:30.160
-correctly
-
-0:19:32.240,0:19:35.440
-well I'm going to go to the next
-
-0:19:33.679,0:19:37.360
-question is there
-
-0:19:35.440,0:19:38.880
-support for images in maximum mode not
-
-0:19:37.360,0:19:43.840
-right now
-
-0:19:38.880,0:19:43.840
-the way I want to implement some imax
-
-0:19:45.280,0:19:51.280
-things uh is there support for
-
-0:19:49.120,0:19:53.360
-but right now it doesn't have like a if
-
-0:19:51.280,0:19:55.600
-you could want to have a new plot
-
-0:19:53.360,0:19:56.720
-um inside you buffer right now it's not
-
-0:19:55.600,0:19:59.360
-possible so
-
-0:19:56.720,0:20:01.200
-that's the thing that I maximized that
-
-0:19:59.360,0:20:03.520
-maxima.l still doesn't
-
-0:20:01.200,0:20:04.720
-do which university you start to use
-
-0:20:03.520,0:20:08.799
-maxima um
-
-0:20:04.720,0:20:11.840
-in this aragosa university from spain
-
-0:20:08.799,0:20:12.640
-they used to maximize the um thing in
-
-0:20:11.840,0:20:16.400
-the engineer
-
-0:20:12.640,0:20:18.320
-and in the math also so I'm 100 sure
-
-0:20:16.400,0:20:19.679
-right now but when I started
-
-0:20:18.320,0:20:22.559
-are you planning to option your package
-
-0:20:19.679,0:20:25.440
-into maxima um I don't know about that
-
-0:20:22.559,0:20:26.320
-because uh maybe can be a little bit
-
-0:20:25.440,0:20:30.720
-messy
-
-0:20:26.320,0:20:32.960
-um because the maxima ripple is more
-
-0:20:30.720,0:20:33.360
-built around like maxima itself and they
-
-0:20:32.960,0:20:37.600
-don't
-
-0:20:33.360,0:20:42.240
-update the interfaces that much
-
-0:20:37.600,0:20:45.360
-I have no problem like it's okay it just
-
-0:20:42.240,0:20:46.320
-you have to um if you want to push you
-
-0:20:45.360,0:20:48.480
-can push in other
-
-0:20:46.320,0:20:49.520
-repository I mean it's just changed the
-
-0:20:48.480,0:20:52.880
-file another way
-
-0:20:49.520,0:20:54.080
-but also the test um is going to be a
-
-0:20:52.880,0:20:55.200
-little bit harder because I think
-
-0:20:54.080,0:20:59.120
-they're using
-
-0:20:55.200,0:21:01.200
-search for and I'm using
-
-0:20:59.120,0:21:02.159
-git lab continue integration within the
-
-0:21:01.200,0:21:06.799
-jury
-
-0:21:02.159,0:21:09.679
-so yeah I don't think that now unmuted
-
-0:21:06.799,0:21:09.679
-yeah it will be nice
-
-0:21:10.799,0:21:14.840
-okay um it's possible to include
-
-0:21:12.799,0:21:16.480
-maximizing or false similar to jupiter
-
-0:21:14.840,0:21:19.919
-notebooks
-
-0:21:16.480,0:21:23.280
-um I mean you can uh use maximize your
-
-0:21:19.919,0:21:26.320
-or files and you have maximum l mod
-
-0:21:23.280,0:21:31.520
-integrated and you can like create put
-
-0:21:26.320,0:21:34.400
-that code into a buffer and then
-
-0:21:31.520,0:21:36.159
-uh edited correctly but it is now not it
-
-0:21:34.400,0:21:37.679
-doesn't have like all the features like
-
-0:21:36.159,0:21:40.480
-other languages because
-
-0:21:37.679,0:21:42.320
-right now uh as my understanding is
-
-0:21:40.480,0:21:45.440
-quite basic so I still have some
-
-0:21:42.320,0:21:47.679
-still needs some some stuff some work
-
-0:21:45.440,0:21:47.679
-around
-
-0:21:47.919,0:21:51.760
-okay I think that's it
-
-0:21:52.320,0:21:55.440
-you are now unmuted
-
-0:21:56.320,0:22:01.919
-yep so that's it uh thank you very much
-
-0:21:59.600,0:22:04.640
