+WEBVTT
+
+00:00:00.320 --> 00:00:03.280
+um so hi I'm joe corneli
+
+00:00:03.280 --> 00:00:05.920
+uh this is work I did with ray puzio and
+
+00:00:05.920 --> 00:00:06.879
+cameron smith
+
+00:00:06.879 --> 00:00:10.559
+um and they're the main protagonists in
+
+00:00:10.559 --> 00:00:11.599
+this story they
+
+00:00:11.599 --> 00:00:14.960
+are uh researchers who've been working
+
+00:00:14.960 --> 00:00:17.840
+on theoretical biology um so in a
+
+00:00:17.840 --> 00:00:20.160
+typical project they may use manxima
+
+00:00:20.160 --> 00:00:23.760
+and julia their work for biology physics
+
+00:00:23.760 --> 00:00:24.800
+and computer science
+
+00:00:24.800 --> 00:00:27.199
+computer science and the latest work in
+
+00:00:27.199 --> 00:00:29.439
+progress is on branching processes for
+
+00:00:29.439 --> 00:00:30.800
+cancer modeling so
+
+00:00:30.800 --> 00:00:34.719
+how can um Emacs possibly help
+
+00:00:34.719 --> 00:00:37.360
+let's let's have a look uh moving code
+
+00:00:37.360 --> 00:00:38.399
+and data between these different
+
+00:00:38.399 --> 00:00:39.680
+programs by hand is
+
+00:00:39.680 --> 00:00:42.000
+annoying on separate workflows for
+
+00:00:42.000 --> 00:00:43.200
+writing up notes and preparing
+
+00:00:43.200 --> 00:00:44.399
+publications
+
+00:00:44.399 --> 00:00:46.000
+is perhaps even more annoying all of
+
+00:00:46.000 --> 00:00:48.640
+it's time consuming and error-prone
+
+00:00:48.640 --> 00:00:52.000
+um so what about maybe using jupiter
+
+00:00:52.000 --> 00:00:53.760
+uh we found something called script of
+
+00:00:53.760 --> 00:00:55.199
+scripts and it solves some of those
+
+00:00:55.199 --> 00:00:58.399
+problems because you can use
+
+00:00:58.399 --> 00:01:01.120
+maximum and julia together but we were
+
+00:01:01.120 --> 00:01:02.640
+quite happy to explore emacs based
+
+00:01:02.640 --> 00:01:05.199
+solutions being emax enthusiasts and we
+
+00:01:05.199 --> 00:01:05.840
+even
+
+00:01:05.840 --> 00:01:07.760
+got cameron to be enthusiastic about
+
+00:01:07.760 --> 00:01:09.200
+doing emacs so that
+
+00:01:09.200 --> 00:01:11.600
+went nice so just here's a little
+
+00:01:11.600 --> 00:01:12.400
+feature grid
+
+00:01:12.400 --> 00:01:15.360
+of emacs org versus just sort of your
+
+00:01:15.360 --> 00:01:16.400
+generic
+
+00:01:16.400 --> 00:01:19.040
+um tools that are in a different more
+
+00:01:19.040 --> 00:01:20.960
+general ecosystem so as you can see it's
+
+00:01:20.960 --> 00:01:21.520
+quite
+
+00:01:21.520 --> 00:01:23.360
+feature complete you've got your maximo
+
+00:01:23.360 --> 00:01:25.520
+mode julia mode you can use both of them
+
+00:01:25.520 --> 00:01:27.119
+inside of org mode
+
+00:01:27.119 --> 00:01:28.720
+you can present things with word tree
+
+00:01:28.720 --> 00:01:30.240
+slide you can set up a
+
+00:01:30.240 --> 00:01:33.280
+wiki inside of orgrome this is one I
+
+00:01:33.280 --> 00:01:33.680
+found
+
+00:01:33.680 --> 00:01:35.759
+rather recently you can even use
+
+00:01:35.759 --> 00:01:37.759
+compatibly with orgrome something called
+
+00:01:37.759 --> 00:01:38.799
+log seek
+
+00:01:38.799 --> 00:01:41.520
+which is in the browser um so that's
+
+00:01:41.520 --> 00:01:42.159
+nice
+
+00:01:42.159 --> 00:01:44.320
+um you can do real-time collaborative
+
+00:01:44.320 --> 00:01:45.840
+editing um
+
+00:01:45.840 --> 00:01:47.840
+either in a kind of pairing style or in
+
+00:01:47.840 --> 00:01:49.280
+a more etherpad style
+
+00:01:49.280 --> 00:01:51.520
+obviously you can manage your references
+
+00:01:51.520 --> 00:01:54.159
+you can typeset whatever you want um you
+
+00:01:54.159 --> 00:01:55.759
+can publish work in progress on a blog
+
+00:01:55.759 --> 00:01:57.439
+and the fern is another one of these
+
+00:01:57.439 --> 00:01:58.159
+external
+
+00:01:58.159 --> 00:02:00.560
+org mode tools it's not actually any mac
+
+00:02:00.560 --> 00:02:01.360
+but works with
+
+00:02:01.360 --> 00:02:03.680
+org mode stuff and you know so we're
+
+00:02:03.680 --> 00:02:04.399
+good to go
+
+00:02:04.399 --> 00:02:06.640
+uh with all of that so what does that
+
+00:02:06.640 --> 00:02:08.000
+look like well here's
+
+00:02:08.000 --> 00:02:09.679
+a little example from before they were
+
+00:02:09.679 --> 00:02:11.599
+doing um
+
+00:02:11.599 --> 00:02:12.800
+before we started really thinking
+
+00:02:12.800 --> 00:02:14.560
+seriously about this stuff so this is
+
+00:02:14.560 --> 00:02:15.599
+just maxima
+
+00:02:15.599 --> 00:02:17.440
+well maximo doesn't have a long running
+
+00:02:17.440 --> 00:02:19.280
+process by default if you've ever used
+
+00:02:19.280 --> 00:02:20.160
+python
+
+00:02:20.160 --> 00:02:22.480
+uh you have something called sessions uh
+
+00:02:22.480 --> 00:02:23.920
+they don't have that for maxim at least
+
+00:02:23.920 --> 00:02:24.959
+not by default
+
+00:02:24.959 --> 00:02:27.599
+um so how what was the workaround
+
+00:02:27.599 --> 00:02:29.360
+there's this thing called uh
+
+00:02:29.360 --> 00:02:32.480
+solve for you here and um
+
+00:02:32.480 --> 00:02:34.879
+that shows up down below again in these
+
+00:02:34.879 --> 00:02:36.319
+angle brackets which you've seen maybe
+
+00:02:36.319 --> 00:02:37.360
+in someone else's talk
+
+00:02:37.360 --> 00:02:40.480
+uh which means go to the previous uh
+
+00:02:40.480 --> 00:02:41.920
+thing that was named soul for you
+
+00:02:41.920 --> 00:02:43.920
+and do that all over again so they do
+
+00:02:43.920 --> 00:02:45.280
+that over again
+
+00:02:45.280 --> 00:02:47.440
+and here's the little maxima code for
+
+00:02:47.440 --> 00:02:49.519
+defining you saw so you've now defined
+
+00:02:49.519 --> 00:02:50.560
+you saw
+
+00:02:50.560 --> 00:02:51.920
+and then you can use it in the next
+
+00:02:51.920 --> 00:02:54.000
+expression you get out a nice juicy
+
+00:02:54.000 --> 00:02:56.560
+zero at the end but it's a little bit a
+
+00:02:56.560 --> 00:02:57.200
+little bit
+
+00:02:57.200 --> 00:02:58.959
+like cartridge in a pear tree to have to
+
+00:02:58.959 --> 00:03:00.640
+redefine everything every time
+
+00:03:00.640 --> 00:03:02.560
+so this is clearly at the level of work
+
+00:03:02.560 --> 00:03:04.159
+around um maybe just
+
+00:03:04.159 --> 00:03:06.879
+one more time going looking through that
+
+00:03:06.879 --> 00:03:07.920
+um
+
+00:03:07.920 --> 00:03:11.599
+that stuff um
+
+00:03:11.599 --> 00:03:13.760
+sorry so uh looking through that stuff
+
+00:03:13.760 --> 00:03:15.280
+this is we're going to need something
+
+00:03:15.280 --> 00:03:17.200
+like that probably for stitching
+
+00:03:17.200 --> 00:03:19.599
+maxima and julie julia together so it's
+
+00:03:19.599 --> 00:03:20.319
+good to
+
+00:03:20.319 --> 00:03:21.680
+look a little bit about how that might
+
+00:03:21.680 --> 00:03:23.920
+work so first of all you can cache
+
+00:03:23.920 --> 00:03:25.680
+results so if you wanted to save the
+
+00:03:25.680 --> 00:03:26.480
+date
+
+00:03:26.480 --> 00:03:28.480
+out of block one at a certain time and
+
+00:03:28.480 --> 00:03:29.920
+then use
+
+00:03:29.920 --> 00:03:32.239
+use it again later so at the time when I
+
+00:03:32.239 --> 00:03:33.280
+ran this code
+
+00:03:33.280 --> 00:03:34.640
+you can see I've got two slightly
+
+00:03:34.640 --> 00:03:36.720
+different time stamps down below one's
+
+00:03:36.720 --> 00:03:38.560
+the cached result and the other was the
+
+00:03:38.560 --> 00:03:40.319
+result of reevaluating
+
+00:03:40.319 --> 00:03:42.640
+the block so you can move things around
+
+00:03:42.640 --> 00:03:43.760
+um and that's
+
+00:03:43.760 --> 00:03:46.000
+that's going to be useful but you know
+
+00:03:46.000 --> 00:03:47.280
+that's not really the main problem the
+
+00:03:47.280 --> 00:03:48.080
+main problem is
+
+00:03:48.080 --> 00:03:50.799
+making maxima long running so kind of
+
+00:03:50.799 --> 00:03:51.440
+the
+
+00:03:51.440 --> 00:03:53.920
+core of this talk is a new observant
+
+00:03:53.920 --> 00:03:56.400
+facility which is a general purpose
+
+00:03:56.400 --> 00:03:59.280
+way to do that kind of thing which
+
+00:03:59.280 --> 00:04:00.560
+involves a very simple
+
+00:04:00.560 --> 00:04:04.239
+change to obcor uh so we'll give a quick
+
+00:04:04.239 --> 00:04:05.360
+overview of that and show
+
+00:04:05.360 --> 00:04:08.480
+an example um so here's the example
+
+00:04:08.480 --> 00:04:11.760
+um a very simple sort of silly example
+
+00:04:11.760 --> 00:04:13.040
+uh what does it mean to have a long
+
+00:04:13.040 --> 00:04:14.640
+running process here I've set this
+
+00:04:14.640 --> 00:04:15.920
+display2d
+
+00:04:15.920 --> 00:04:18.560
+to be false um which just means that
+
+00:04:18.560 --> 00:04:19.440
+things are going to come
+
+00:04:19.440 --> 00:04:22.320
+come across in 1d and then I ask it to
+
+00:04:22.320 --> 00:04:23.040
+expand
+
+00:04:23.040 --> 00:04:25.199
+uh something and I get latex by default
+
+00:04:25.199 --> 00:04:27.280
+so so that's what it means is I've sent
+
+00:04:27.280 --> 00:04:28.639
+something in and it's going to come
+
+00:04:28.639 --> 00:04:30.240
+across in one view which is great
+
+00:04:30.240 --> 00:04:32.080
+um maybe you'll also notice that there's
+
+00:04:32.080 --> 00:04:34.560
+no semicolon if you're a maxima fan
+
+00:04:34.560 --> 00:04:36.720
+um and things are coming across as tech
+
+00:04:36.720 --> 00:04:38.400
+so those were some little bonus features
+
+00:04:38.400 --> 00:04:40.320
+and I'll show you how that works later
+
+00:04:40.320 --> 00:04:41.040
+so
+
+00:04:41.040 --> 00:04:45.440
+um the change to obcor is as follows uh
+
+00:04:45.440 --> 00:04:48.880
+um we uh actually this should say uh
+
+00:04:48.880 --> 00:04:51.520
+instead of stream here it should say um
+
+00:04:51.520 --> 00:04:52.479
+servant
+
+00:04:52.479 --> 00:04:54.800
+sorry uh we tried an experimental
+
+00:04:54.800 --> 00:04:56.160
+version what's called stream so now it's
+
+00:04:56.160 --> 00:04:58.160
+called servant but all it does is it
+
+00:04:58.160 --> 00:05:01.520
+overrides uh or babel execute laying for
+
+00:05:01.520 --> 00:05:02.639
+arbitrary laying
+
+00:05:02.639 --> 00:05:05.919
+if you have um a servant
+
+00:05:05.919 --> 00:05:07.840
+in your in your params so that's the
+
+00:05:07.840 --> 00:05:09.759
+change that hasn't been
+
+00:05:09.759 --> 00:05:11.919
+pushed out or sent as a patch to anybody
+
+00:05:11.919 --> 00:05:13.759
+but it's a pretty minor change
+
+00:05:13.759 --> 00:05:16.960
+um here's an overview without the code
+
+00:05:16.960 --> 00:05:19.080
+of just a high level overview of
+
+00:05:19.080 --> 00:05:20.720
+observant.el so
+
+00:05:20.720 --> 00:05:22.160
+it stores information about these
+
+00:05:22.160 --> 00:05:24.479
+processes in a hash table
+
+00:05:24.479 --> 00:05:26.080
+it can do pre-processing and
+
+00:05:26.080 --> 00:05:27.600
+post-processing
+
+00:05:27.600 --> 00:05:29.759
+um it does all these things it stores
+
+00:05:29.759 --> 00:05:30.720
+the output
+
+00:05:30.720 --> 00:05:32.479
+I mentioned here that in principle we
+
+00:05:32.479 --> 00:05:34.080
+could store lots of output and have a
+
+00:05:34.080 --> 00:05:35.280
+kind of browsable
+
+00:05:35.280 --> 00:05:36.560
+history although we don't do that
+
+00:05:36.560 --> 00:05:38.880
+presently um but that's what observant
+
+00:05:38.880 --> 00:05:40.639
+does is it does what you might expect
+
+00:05:40.639 --> 00:05:41.440
+and here's the
+
+00:05:41.440 --> 00:05:45.440
+here's the maxima kind of um
+
+00:05:45.440 --> 00:05:48.160
+on-ramp uh to get maxima brought in so
+
+00:05:48.160 --> 00:05:49.600
+you have to obviously have a maximum
+
+00:05:49.600 --> 00:05:51.360
+process you can call
+
+00:05:51.360 --> 00:05:54.960
+um put hash uh this is the preprocessing
+
+00:05:54.960 --> 00:05:57.840
+thing I mentioned adding in some tech um
+
+00:05:57.840 --> 00:05:58.960
+and adding in
+
+00:05:58.960 --> 00:06:01.520
+uh or deleting rather a substring and
+
+00:06:01.520 --> 00:06:03.120
+here here is why you delete the
+
+00:06:03.120 --> 00:06:03.759
+substring
+
+00:06:03.759 --> 00:06:06.960
+is because um maxima thinks it's a good
+
+00:06:06.960 --> 00:06:08.240
+idea to tell you false
+
+00:06:08.240 --> 00:06:10.080
+once you once you run check on things
+
+00:06:10.080 --> 00:06:11.759
+you've got to delete that back out to
+
+00:06:11.759 --> 00:06:13.680
+get something kind of coherent out of it
+
+00:06:13.680 --> 00:06:16.960
+but so this is how to set up maximal um
+
+00:06:16.960 --> 00:06:19.280
+that's enough really of the demo is not
+
+00:06:19.280 --> 00:06:20.000
+really a demos for
+
+00:06:20.000 --> 00:06:21.919
+show and tell but uh this is an
+
+00:06:21.919 --> 00:06:23.600
+experience report I wanted to talk about
+
+00:06:23.600 --> 00:06:25.440
+the experience of doing this
+
+00:06:25.440 --> 00:06:28.080
+so some some negatives like we tried to
+
+00:06:28.080 --> 00:06:30.160
+get emacs jupiter working
+
+00:06:30.160 --> 00:06:33.199
+prior to prior to working on the um
+
+00:06:33.199 --> 00:06:36.000
+observant and we couldn't get it doing
+
+00:06:36.000 --> 00:06:37.919
+everything we wanted despite a bit of
+
+00:06:37.919 --> 00:06:40.160
+heavy lifting and debugging and stuff so
+
+00:06:40.160 --> 00:06:41.840
+that's not not finished that was a bit
+
+00:06:41.840 --> 00:06:42.880
+difficult
+
+00:06:42.880 --> 00:06:45.360
+um on the other hand working on
+
+00:06:45.360 --> 00:06:47.759
+observing was fun and pretty lightweight
+
+00:06:47.759 --> 00:06:48.479
+and easy
+
+00:06:48.479 --> 00:06:50.400
+um we got some experience co-editing
+
+00:06:50.400 --> 00:06:52.400
+things with these real-time tools
+
+00:06:52.400 --> 00:06:54.479
+obviously the stack is somewhat work in
+
+00:06:54.479 --> 00:06:55.919
+progress um
+
+00:06:55.919 --> 00:06:58.000
+so I just wanted to give a shout out to
+
+00:06:58.000 --> 00:07:00.800
+crdt which was really fun
+
+00:07:00.800 --> 00:07:03.919
+and champion was making bug fiction
+
+00:07:03.919 --> 00:07:07.039
+bug fixes for that as we go similarly
+
+00:07:07.039 --> 00:07:08.960
+for fern and log seek the maintainers
+
+00:07:08.960 --> 00:07:10.160
+were really responsive
+
+00:07:10.160 --> 00:07:12.960
+um and so that was nice we did try to
+
+00:07:12.960 --> 00:07:14.560
+get emacs running in the browser
+
+00:07:14.560 --> 00:07:15.840
+thinking it would be really nice for
+
+00:07:15.840 --> 00:07:16.880
+people who
+
+00:07:16.880 --> 00:07:19.520
+um didn't want to install it to get a
+
+00:07:19.520 --> 00:07:21.120
+chance to just try it
+
+00:07:21.120 --> 00:07:23.120
+uh but actually browsers capture things
+
+00:07:23.120 --> 00:07:24.479
+like uh control n
+
+00:07:24.479 --> 00:07:27.120
+and so that's that was a bit annoying
+
+00:07:27.120 --> 00:07:28.479
+but we did get lots of great feedback
+
+00:07:28.479 --> 00:07:29.759
+and interaction with people including
+
+00:07:29.759 --> 00:07:31.599
+around this conference so thank you
+
+00:07:31.599 --> 00:07:33.759
+to those who we've had discussions with
+
+00:07:33.759 --> 00:07:35.599
+um
+
+00:07:35.599 --> 00:07:37.680
+so future work okay so maybe you
+
+00:07:37.680 --> 00:07:38.639
+remember I didn't
+
+00:07:38.639 --> 00:07:41.039
+give a talk a few years back on arcana
+
+00:07:41.039 --> 00:07:42.400
+so what what
+
+00:07:42.400 --> 00:07:44.479
+might this have to do with org mode and
+
+00:07:44.479 --> 00:07:45.919
+that's always the question one asks
+
+00:07:45.919 --> 00:07:47.039
+about arcata
+
+00:07:47.039 --> 00:07:48.720
+well so arcana one of the things it does
+
+00:07:48.720 --> 00:07:50.319
+is transclusions and so that could be
+
+00:07:50.319 --> 00:07:51.680
+actually very helpful
+
+00:07:51.680 --> 00:07:54.000
+in connection with this combined notes
+
+00:07:54.000 --> 00:07:55.520
+and write-up workflow so you might have
+
+00:07:55.520 --> 00:07:56.479
+a
+
+00:07:56.479 --> 00:07:58.400
+forward mode uh and some of these
+
+00:07:58.400 --> 00:08:00.800
+results we got back as raw results
+
+00:08:00.800 --> 00:08:03.199
+could go right into your write up in a
+
+00:08:03.199 --> 00:08:03.919
+kind of
+
+00:08:03.919 --> 00:08:07.520
+convenient way at a level above um
+
+00:08:07.520 --> 00:08:09.039
+transparently a level above the notebook
+
+00:08:09.039 --> 00:08:11.280
+so you'd have the notebook alongside the
+
+00:08:11.280 --> 00:08:13.440
+write-up in that case
+
+00:08:13.440 --> 00:08:15.599
+which is a sort of variation on the
+
+00:08:15.599 --> 00:08:16.800
+literate programming
+
+00:08:16.800 --> 00:08:19.120
+workflow this is speculative who knows
+
+00:08:19.120 --> 00:08:20.000
+the other thought is
+
+00:08:20.000 --> 00:08:22.080
+it just relates to the idea of network
+
+00:08:22.080 --> 00:08:23.520
+programming so we can imagine these
+
+00:08:23.520 --> 00:08:24.800
+networks of
+
+00:08:24.800 --> 00:08:26.639
+computational nodes maybe sitting inside
+
+00:08:26.639 --> 00:08:28.800
+of orgrome calling each other
+
+00:08:28.800 --> 00:08:31.199
+um and you would want to maintain some
+
+00:08:31.199 --> 00:08:32.560
+kind of model of that
+
+00:08:32.560 --> 00:08:34.959
+process and a sort of general question
+
+00:08:34.959 --> 00:08:36.640
+is how do we have a remote control for
+
+00:08:36.640 --> 00:08:38.320
+long-running processes you could do that
+
+00:08:38.320 --> 00:08:40.240
+in lisp or closure but
+
+00:08:40.240 --> 00:08:42.479
+maybe we could have something a little
+
+00:08:42.479 --> 00:08:44.080
+bit like that here
+
+00:08:44.080 --> 00:08:45.839
+um so conclusions what have we actually
+
+00:08:45.839 --> 00:08:48.080
+addressed well uh we addressed uh
+
+00:08:48.080 --> 00:08:50.080
+accessing any long-running process with
+
+00:08:50.080 --> 00:08:51.600
+a simple or mode interface
+
+00:08:51.600 --> 00:08:52.959
+obviously we're not the only people to
+
+00:08:52.959 --> 00:08:54.880
+think about notebooks but we think that
+
+00:08:54.880 --> 00:08:56.880
+emacs has some advantages
+
+00:08:56.880 --> 00:08:58.880
+related to reproducible research and
+
+00:08:58.880 --> 00:09:01.120
+interdisciplinary collaboration so let's
+
+00:09:01.120 --> 00:09:01.680
+just
+
+00:09:01.680 --> 00:09:03.120
+say that we think something is
+
+00:09:03.120 --> 00:09:04.880
+reproducible if it's actually teachable
+
+00:09:04.880 --> 00:09:07.200
+to someone new and they can do it
+
+00:09:07.200 --> 00:09:09.279
+org mode seems very useful for that many
+
+00:09:09.279 --> 00:09:11.680
+of the other talks have touched on this
+
+00:09:11.680 --> 00:09:14.399
+interdisciplinary collaboration is great
+
+00:09:14.399 --> 00:09:16.000
+this was an interdisciplinary
+
+00:09:16.000 --> 00:09:17.839
+collaboration on some level but
+
+00:09:17.839 --> 00:09:19.680
+what about you know future work for
+
+00:09:19.680 --> 00:09:21.600
+bringing in scenario planners simulation
+
+00:09:21.600 --> 00:09:22.320
+scientists
+
+00:09:22.320 --> 00:09:24.480
+and local farmers and building something
+
+00:09:24.480 --> 00:09:25.519
+that they can all
+
+00:09:25.519 --> 00:09:27.200
+use that's more than the sum of the
+
+00:09:27.200 --> 00:09:29.200
+parts so a little
+
+00:09:29.200 --> 00:09:30.720
+future work for everybody else here so
+
+00:09:30.720 --> 00:09:32.160
+we think science should be widely
+
+00:09:32.160 --> 00:09:33.120
+teachable
+
+00:09:33.120 --> 00:09:34.560
+shareable semi-automated
+
+00:09:34.560 --> 00:09:36.720
+transdisciplinary and real time
+
+00:09:36.720 --> 00:09:40.399
+like EmacsConf so you can get in touch
+
+00:09:40.399 --> 00:09:43.279
+uh via these methods and the code which
+
+00:09:43.279 --> 00:09:44.560
+is very much early stage work in
+
+00:09:44.560 --> 00:09:45.200
+progress
+
+00:09:45.200 --> 00:09:46.640
+as this was meant to be an experience
+
+00:09:46.640 --> 00:09:48.800
+report not a it's all done here it is
+
+00:09:48.800 --> 00:09:49.920
+polished report
+
+00:09:49.920 --> 00:09:51.680
+um it's also online if you'd like to
+
+00:09:51.680 --> 00:09:53.360
+have a look so that's the end of the
+
+00:09:53.360 --> 00:09:54.560
+talk and I don't know if there's time
+
+00:09:54.560 --> 00:09:55.279
+for questions
+
+00:09:55.279 --> 00:09:57.440
+or not but um I'm at your disposal now
+
+00:09:57.440 --> 00:10:00.240
+thank you you are now unmuted
+
+00:10:00.240 --> 00:10:04.079
+um many thanks for the tough job
+
+00:10:04.079 --> 00:10:07.120
+uh let's see we have about I think four
+
+00:10:07.120 --> 00:10:08.880
+minutes four questions
+
+00:10:08.880 --> 00:10:10.880
+um and we have a couple of questions on
+
+00:10:10.880 --> 00:10:12.320
+the pad would you like to read them
+
+00:10:12.320 --> 00:10:14.240
+yourself or should I read them to you
+
+00:10:14.240 --> 00:10:16.560
+uh just for sake of easy management why
+
+00:10:16.560 --> 00:10:18.079
+don't you read them out if that's okay
+
+00:10:18.079 --> 00:10:21.279
+yeah sure uh so they ask have you looked
+
+00:10:21.279 --> 00:10:22.240
+into trying
+
+00:10:22.240 --> 00:10:25.440
+sage math I've long uh long wanted
+
+00:10:25.440 --> 00:10:33.760
+nothing org files
+
+00:10:33.760 --> 00:10:36.959
+right and I and I wrote the answer that
+
+00:10:36.959 --> 00:10:39.279
+we should be possible because one can
+
+00:10:39.279 --> 00:10:44.839
+call it from a command
+
+00:10:44.839 --> 00:10:46.399
+okay
+
+00:10:46.399 --> 00:10:48.640
+and I see there's another sagemath
+
+00:10:48.640 --> 00:10:50.079
+question that you seem to have answered
+
+00:10:50.079 --> 00:10:52.100
+as well so I guess I won't repeat that
+
+00:10:52.100 --> 00:10:54.880
+[Music]
+
+00:10:54.880 --> 00:10:56.959
+there's let's not forget about embedded
+
+00:10:56.959 --> 00:11:00.640
+calc in emacs
+
+00:11:00.640 --> 00:11:03.680
+so so the first demos actually were with
+
+00:11:03.680 --> 00:11:05.040
+calc so that's that's
+
+00:11:05.040 --> 00:11:06.640
+useful uh although I think it was a
+
+00:11:06.640 --> 00:11:07.839
+different kind of a different command
+
+00:11:07.839 --> 00:11:08.240
+line
+
+00:11:08.240 --> 00:11:11.839
+well that was the next calc yeah
+
+00:11:11.839 --> 00:11:13.839
+so sure there is there is calc so that
+
+00:11:13.839 --> 00:11:15.680
+would be calculus and
+
+00:11:15.680 --> 00:11:19.120
+calc is already in org mode yeah
+
+00:11:19.120 --> 00:11:25.680
+yeah yeah
+
+00:11:25.680 --> 00:11:39.760
+um still looking for questions
+
+00:11:39.760 --> 00:11:41.760
+okay I think that's about it I don't see
+
+00:11:41.760 --> 00:11:44.320
+any questions on the ether pad
+
+00:11:44.320 --> 00:11:47.440
+and let's see
+
+00:11:47.440 --> 00:11:53.040
+anything on irc
+
+00:11:53.040 --> 00:11:55.760
+um nothing but phrases and everyone
+
+00:11:55.760 --> 00:11:56.720
+thanking you
+
+00:11:56.720 --> 00:11:59.120
+thank you all right you're welcome
+
+00:11:59.120 --> 00:12:00.240
+thanks a lot uh
+
+00:12:00.240 --> 00:12:02.880
+we'll see you guys around then cheers
+
+00:12:02.880 --> 00:12:06.800
+and see you around
