-[Speaker 0]: And he can hear us. Can you perhaps do it for +00:00:00.000 --> 00:00:01.839 +[Speaker 0]: You can hear us. Can you perhaps do it for
+00:00:01.839 --> 00:00:03.740 me? Great. The little angels in the
+00:00:03.740 --> 00:00:05.140 background have done it for me.
-So now, finally, that everything is ready. +00:00:05.240 --> 00:00:07.759 +So now finally that everything is ready.
-Hi, James. How are you doing? +00:00:07.759 --> 00:00:09.099 +Hi James, how are you doing?
-[Speaker 1]: Good morning. Hello. +00:00:13.780 --> 00:00:14.599 +Good morning. Hello. Well,
-[Speaker 0]: Well, thank you for your talk. +00:00:14.599 --> 00:00:16.320 +thank you for your talk and sorry for the
-And sorry for the little hiccup at the middle +00:00:16.320 --> 00:00:19.240 +little hiccup at the middle we had to pull
-we had to put out a fire with the audio +00:00:19.240 --> 00:00:20.900 +out a fire with the audio going out in the
-going out in the middle and sorry about this. +00:00:20.900 --> 00:00:22.580 +middle and sorry about this.
+00:00:23.140 --> 00:00:24.040 [Speaker 1]: It's no trouble.
+00:00:25.240 --> 00:00:28.680 [Speaker 0]: So James, you've obviously told us about your
+00:00:28.680 --> 00:00:30.220 very fancy setup with the green screen and
+00:00:30.220 --> 00:00:32.840 I'm sad to see that you haven't put out the
+00:00:32.840 --> 00:00:35.579 green screen for your BBB session right now.
+00:00:35.579 --> 00:00:37.060 Do you have it in the background just for
-you? Right, okay. It wasn't that far. +00:00:37.060 --> 00:00:40.400 +you? Right, okay, it wasn't that far.
-Great. No. So, I'm just going to ask. +00:00:40.600 --> 00:00:44.180 +Great. So I'm just going to ask,
-So, this is the first live Q&A that we have +00:00:44.180 --> 00:00:47.440 +so this is the first live Q&A that we have
-for this session, so things might be coming +00:00:47.440 --> 00:00:49.300 +for the session so things might be coming
-into place, so pardon us if we take a little +00:00:49.300 --> 00:00:51.600 +into place so pardon us if we take a little
+00:00:51.600 --> 00:00:54.340 bit of time to put the questions on the
+00:00:54.340 --> 00:00:55.780 screen and all of this.
-What I'm gonna do, I'm just gonna load up the +00:00:56.400 --> 00:00:57.940 +What I'm going to do, I'm just going to load
-pad. I would invite James to also open the +00:00:57.940 --> 00:01:02.660 +up the pad. I would invite James to also open
-pad on his hand. Sorry, +00:01:02.660 --> 00:01:04.200 +the pad on his hand. So yeah,
+00:01:04.200 --> 00:01:05.740 I've got people talking in my ears and it's
+00:01:05.740 --> 00:01:07.740 been a while since I've last had this.
-Okay, so opening the talks right now. +00:01:08.260 --> 00:01:11.979 +And okay, so opening the talks right now,
-Opening the pad, if I can find it. +00:01:12.100 --> 00:01:14.120 +opening the pad if I can find it.
-Open the pad. Okay. Have you got the pad open +00:01:14.120 --> 00:01:19.020 +Open up the pad. Okay.
-[Speaker 1]: So I can read the question. +00:01:19.200 --> 00:01:21.240 +So have you got a pad open on your end,
-[Speaker 0]: on your end, James? Okay, +00:01:21.240 --> 00:01:22.800 +James? So I can read the question.
-great. Opening it on my end as well. +00:01:23.119 --> 00:01:26.740 +So, okay, great. Opening it on my end as
-What I'm going to do, folks, +00:01:26.740 --> 00:01:28.360 +well. What I'm going to do,
-I see some of you have joined us on, +00:01:28.360 --> 00:01:30.360 +folks, I see some of you have joined us.
-if I show you, some of the people that have +00:01:39.900 --> 00:01:42.500 +I'm going to start doing is first taking
-joined us in the BBB room. +00:01:42.500 --> 00:01:44.220 +questions in the other part because it's a
-You can join us as well, +00:01:44.220 --> 00:01:46.200 +little faster to ask questions like this.
-all the links are on the talk page or on ISE, +00:01:46.520 --> 00:01:48.160 +And then as soon as we've finished,
-you can find it very easily. -
-But what I'm going to start doing is first -
-taking questions in the other pad because -
-it's a little faster to ask questions like -
-this, and then as soon as we've finished, -
+00:01:48.160 --> 00:01:49.920 feel free to unmute yourself and ask your
-questions. All right, so I've got some +00:01:49.920 --> 00:01:54.180 +questions. All right so I've got some
-reactions about OBS being cool and yes, +00:01:54.180 --> 00:01:57.660 +reactions about OBS being cool and yes both
-both James and I will be able to tell you +00:01:57.660 --> 00:01:59.340 +James and I will be able to tell you that
-that it's very cool. We do very fancy stuff +00:01:59.340 --> 00:02:01.720 +it's very cool we do very fancy stuff like
-like when I need to talk to production in the +00:02:04.060 --> 00:02:05.640 +when I need to talk to production in the
+00:02:05.640 --> 00:02:07.540 background and all the stuff obviously that
+00:02:07.540 --> 00:02:09.160 James has been able to show you with a green
+00:02:09.160 --> 00:02:12.800 screen. So I don't see a whole lot of
+00:02:12.800 --> 00:02:15.560 questions so far. I see a lot of reactions on
-publishing lectures book and a classic +00:02:16.020 --> 00:02:17.760 +publishing lectures book and of a classic
+00:02:17.760 --> 00:02:19.700 example is John Kitchens obviously.
-Pedagogy first developments macros are a cool +00:02:20.900 --> 00:02:22.180 +Pedagogy first developments. + +00:02:23.360 --> 00:02:24.660 +Macros are a cool idea.
-idea. Okay questions so how do you overlap +00:02:25.680 --> 00:02:28.820 +Okay questions. So how do you overlap
-yourself with a presentation it's so cool. +00:02:28.820 --> 00:02:30.160 +yourself with a presentation.
-[Speaker 1]: It's quite simple OBS provides filters for +00:02:30.420 --> 00:02:34.680 +It's so cool. It's quite simple.
-you can have a separate filter for each video +00:02:36.420 --> 00:02:40.200 +[Speaker 1]: OBS provides filters for every...
-feed. And 1 of the filters that's available +00:02:40.200 --> 00:02:42.440 +You can have a separate filter for each video
-is chroma key. You just choose a color to +00:02:42.440 --> 00:02:44.960 +feed and 1 of the filters that's available is
-make transparent and just make sure that the +00:02:44.960 --> 00:02:47.840 +chroma key. You just choose a color to make
+00:02:47.840 --> 00:02:52.020 +transparent and just make sure that the + +00:02:52.020 --> 00:02:56.140 webcam is at the top of the composition.
+00:02:57.180 --> 00:03:00.900 And the thing that surprised me the most was
+00:03:00.900 --> 00:03:05.420 how quickly my brain was able to mirror
+00:03:05.420 --> 00:03:07.360 everything and control my body from a
+00:03:07.360 --> 00:03:10.720 separate point of view like the way weather
+00:03:10.720 --> 00:03:15.300 broadcasts are done. It took seconds to be
+00:03:15.300 --> 00:03:16.980 able to do that. Well,
+00:03:16.980 --> 00:03:20.200 and now I have years of practice because that
-setup that you saw that I used to record this +00:03:20.320 --> 00:03:22.740 +set up that you saw that I used to record + +00:03:22.740 --> 00:03:26.960 +this video. I used for years during the
-video, I used for years during the pandemic +00:03:26.960 --> 00:03:32.180 +pandemic for 4 or 5 semesters to because my
-for 4 or 5 semesters to, +00:03:32.180 --> 00:03:33.760 +courses are all have 2,
-because my courses are all have 2, +00:03:33.760 --> 00:03:36.440 +3, 400 students, except for the English
-3, 400 students, except for the English class +00:03:36.440 --> 00:03:38.200 +class, which has, you know,
-which has you know 30 students and so during +00:03:38.200 --> 00:03:41.100 +30 students. And so during the pandemic,
-the pandemic and even after lockdowns were no +00:03:41.200 --> 00:03:44.040 +and even after lockdowns were no longer
-longer mandated I taught online just because +00:03:44.040 --> 00:03:46.160 +mandated, I taught online just because I
-I didn't want to have so many students in the +00:03:46.160 --> 00:03:48.340 +didn't want to have so many students in the
+00:03:48.340 --> 00:03:49.500 room at the same time.
-So I've yeah I'm it I have a lot of practice +00:03:49.600 --> 00:03:53.680 +So I've yeah, I'm it. I have a lot of
-doing that. +00:03:53.680 --> 00:03:54.840 +practice doing that.
-[Speaker 0]: But it pays off because it looks so natural +00:03:56.120 --> 00:03:58.300 +[Speaker 0]: But it pays off because it looks so natural,
-you know it feels like it's the same thing +00:03:58.300 --> 00:04:00.140 +you know, it feels like it's the same thing
-with weather casters you know it sounds very +00:04:00.140 --> 00:04:01.520 +with weathercasters, you know,
-it looks very easy to do but it also takes +00:04:01.520 --> 00:04:03.940 +it sounds very it looks very easy to do,
-quite a bit of practice. +00:04:03.940 --> 00:04:05.780 +but it also takes quite a bit of practice.
+00:04:07.020 --> 00:04:08.300 1 of the things that you also need to
+00:04:08.300 --> 00:04:10.160 remember if you're using a chroma key that
+00:04:10.160 --> 00:04:11.880 James has explained is that you need to have
-very good lighting basically for the color to +00:04:11.880 --> 00:04:14.360 +very good lighting, basically for the color
-pop out in the background and for your body +00:04:14.440 --> 00:04:16.320 +to pop out in the background and for your
-to be easily highlightable. +00:04:16.320 --> 00:04:18.360 +body to be easily highlightable.
+00:04:19.399 --> 00:04:21.240 Okay, were you finished with this question?
+00:04:23.240 --> 00:04:24.980 [Speaker 1]: Yeah, let's take another 1.
+00:04:25.640 --> 00:04:28.580 [Speaker 0]: Sure. So how do you deal with video in Beam?
+00:04:28.700 --> 00:04:30.720 I found it so hard to do that.
+00:04:30.720 --> 00:04:33.060 PPT on the other end is easier to achieve.
+00:04:36.380 --> 00:04:41.480 [Speaker 1]: Yeah, so remember that the slides get
+00:04:41.480 --> 00:04:46.960 produced from Org Mode as PDFs.
-Well, and in fact, even before when I was +00:04:47.540 --> 00:04:50.080 +Well, and in fact, I even before when I was
-using other software to produce slides I +00:04:50.080 --> 00:04:52.540 +using other software to produce slides,
-produced them as PDFs precisely because I +00:04:52.580 --> 00:04:54.220 +I produced them as PDFs,
-wanted to be able to mark them up on on the +00:04:54.720 --> 00:04:56.840 +precisely because I wanted to be able to mark
-screen with the stylus And so I don't do +00:04:56.840 --> 00:05:00.040 +them up on on the screen with the stylus.
-video in the slides. I use OBS to switch from +00:05:02.100 --> 00:05:05.960 +And so I don't do video in the slides.
-static slides that I mark up with the stylus +00:05:06.140 --> 00:05:09.140 +I use OBS to switch from static slides that I
-over to some kind of video viewer and then +00:05:09.140 --> 00:05:12.540 +mark up with the stylus over to some kind of
-back. And again that's how I can use Firefox. +00:05:12.840 --> 00:05:15.360 +video viewer and then back.
+00:05:15.620 --> 00:05:17.820 +And again, that's how I can use Firefox. + +00:05:17.900 --> 00:05:21.880 I use OBS to switch between Firefox and video
-and the Shornal++ program where I can mark up +00:05:22.360 --> 00:05:26.380 +and the Shornell plus plus program where I
-slides. So those functionalities are... +00:05:26.380 --> 00:05:31.060 +can mark up slides. So those functionalities
-That's why I use different software and pull +00:05:31.160 --> 00:05:35.140 +are that's why I use different software and
-it all together with OBS so that I can have +00:05:35.140 --> 00:05:37.440 +pull it all together with OBS so that I can
-lots of functional flexibility. +00:05:37.440 --> 00:05:41.700 +have lots of functional flexibility.
+00:05:44.660 --> 00:05:47.700 [Speaker 0]: Great. Do you ever use things like
+00:05:47.700 --> 00:05:50.960 org-present and stay for the PowerPoint
+00:05:51.060 --> 00:05:53.200 slides? I'm not sure exactly how to read this
-particular question, but at least we can -
-focus on org-present. Are you familiar with +00:05:53.200 --> 00:05:54.860 +particular question but at least we can focus
-what it is? +00:05:54.860 --> 00:05:56.840 +on org-present. Are you familiar with what it
-[Speaker 1]: I've played around with org-present, +00:05:56.840 --> 00:05:57.340 +is?
-And again, I guess you could use OrgPresent +00:05:58.080 --> 00:06:01.920 +[Speaker 1]: I have played around with org-present and
-to show images and to show headings as +00:06:02.380 --> 00:06:07.640 +again I guess you could use org-present to
-slides. But again, Because it's such a +00:06:07.640 --> 00:06:12.160 +show images and to show headings as slides.
-crucial functionality to be able to mark them +00:06:13.140 --> 00:06:17.680 +But again, because I'm it's such a crucial
-up with a stylus. I didn't really show this +00:06:18.100 --> 00:06:21.520 +functionality to be able to mark them up with
-very much, but I also highlight things the +00:06:22.120 --> 00:06:25.760 +stylus. I didn't really show this very much,
-way I would highlight using a laser pointer +00:06:25.760 --> 00:06:27.780 +but I also highlight things the way I would
-on the screen. And again, +00:06:27.780 --> 00:06:30.080 +highlight using a laser pointer on the
-I don't see Emacs being able to do that for +00:06:30.080 --> 00:06:36.300 +screen. And again, I don't see Emacs being
-another couple of generations. +00:06:36.300 --> 00:06:38.500 +able to do that for another couple of
-So really the only thing I use Emacs for +00:06:38.560 --> 00:06:42.800 +generations. So really the only thing I use
-during presentations is to narrow headings +00:06:42.800 --> 00:06:47.360 +Emacs for during presentations is to narrow
-that we can focus on particular text +00:06:48.940 --> 00:06:52.100 +headings that we can focus on particular text
excerpts.
-[Speaker 0]: Right, yeah. A lot of our presentations at +00:06:55.680 --> 00:06:59.200 +[Speaker 0]: Right. Yeah. A lot of our presentation at
+00:06:59.200 --> 00:07:00.420 EmacsConf are usually,
-especially the Org Mode ones, +00:07:00.420 --> 00:07:02.260 +especially the Org Mode ones are done with
-are done with Org Present. +00:07:02.260 --> 00:07:06.740 +OrgPresent. And. Sorry,
-Sorry, I had someone talk to me in the ear. +00:07:06.740 --> 00:07:08.920 +I had again someone talk to me in a year.
-You know the problem with EmacsConf is that +00:07:09.240 --> 00:07:11.440 +You know, the problem with EmacsConf is that
-every year, you have to relearn a lot of +00:07:11.680 --> 00:07:13.440 +every year, you know, you have to relearn a
-skills, and by the time we finish, +00:07:13.440 --> 00:07:16.780 +lot of skills. And by the time we finished by
-by Sunday evening, we are masters of it. +00:07:16.780 --> 00:07:19.900 +Sunday evening we are masters of it and then
-And then we forget everything by the time the +00:07:19.900 --> 00:07:21.820 +we forget everything by the time the next
-next year comes around. +00:07:21.820 --> 00:07:24.280 +year comes around. What I was going to say is
-What I was going to say is that org-present +00:07:24.280 --> 00:07:26.780 +that org-present is often used by people
-is often used by people inside Emacs, +00:07:27.440 --> 00:07:30.940 +inside Emacs conf presenting about org-mode
-Conf, presenting about org-mode. +00:07:31.100 --> 00:07:32.800 +but yeah whenever you need to do something a
-But yeah, whenever you need to do something a -
+00:07:32.800 --> 00:07:34.340 little more visual, it gets a little more
+00:07:34.340 --> 00:07:36.540 complicated. Some people have tried to do
+00:07:36.540 --> 00:07:39.200 fancy stuff with SVG, which is probably the
+00:07:39.200 --> 00:07:41.180 path forward for this type of stuff.
+00:07:41.400 --> 00:07:43.220 But yeah, if you need to draw,
+00:07:43.380 --> 00:07:44.480 if you need to highlight,
+00:07:44.760 --> 00:07:46.360 it is pretty complicated.
+00:07:46.820 --> 00:07:48.340 Perhaps something that you might want to be
+00:07:48.340 --> 00:07:50.940 interested, James, in checking out is PDF
-Tools, which is a way to open up a PDF in +00:07:50.940 --> 00:07:56.040 +tools, which is a way to open up a PDF in
+00:07:56.040 --> 00:07:59.440 Emacs. And this allows you to have basic PDF
+00:07:59.440 --> 00:08:01.560 annotations, like putting a little bit of a
+00:08:01.560 --> 00:08:04.160 Nikon on it. Perhaps you've already played
+00:08:04.160 --> 00:08:04.900 with it.
-[Speaker 1]: I have used that. PDF Tools is an incredible +00:08:06.260 --> 00:08:09.980 +[Speaker 1]: I have used that. PDF tools is an incredible
+00:08:10.080 --> 00:08:14.560 package but until it allows me to make a mark
+00:08:14.560 --> 00:08:18.280 on the screen that shows up in a video
+00:08:18.280 --> 00:08:21.000 compositor. It's not going to replace
-Shornal. +00:08:21.420 --> 00:08:21.920 +Shortenel. + +00:08:23.240 --> 00:08:24.600 +[Speaker 0]: Definitely. All right.
-[Speaker 0]: Definitely. Alright, moving on to the next +00:08:24.600 --> 00:08:25.940 +Moving on to the next question.
-question. Is the triple-accolade syntax an +00:08:26.400 --> 00:08:28.900 +Is the triple-accolade syntax an Org Mode
-[Speaker 2]: Org Mode core feature that I missed so +00:08:28.900 --> 00:08:31.360 +core feature that I missed so far or did you
-[Speaker 0]: far, or did you program that? +00:08:31.360 --> 00:08:33.120 +program that and thank you for the great
-And thank you for the great talk. +00:08:33.120 --> 00:08:33.620 +talk.
+00:08:36.659 --> 00:08:38.360 [Speaker 1]: Thank you very much. No,
+00:08:38.360 --> 00:08:43.220 it's just part of all of the export backends.
+00:08:43.299 --> 00:08:45.060 Actually, I think the way it works is it
+00:08:45.060 --> 00:08:47.040 precedes all of the export backends.
+00:08:47.040 --> 00:08:50.280 When you export, the first thing that happens
+00:08:50.280 --> 00:08:52.360 is expansion of macros.
+00:08:52.720 --> 00:08:56.260 And that's a built-in org mode feature.
+00:08:56.640 --> 00:08:59.690 It's definitely beyond my Emacs Lisp powers
+00:08:59.690 --> 00:09:01.360 to be able to have made something that
+00:09:01.360 --> 00:09:06.920 powerful. That's right.
+00:09:07.020 --> 00:09:08.540 I have come a long way.
-[Speaker 0]: For now, for now. You know, +00:09:02.640 --> 00:09:11.500 +[Speaker 0]: For now. You know, we always,
-we always, you know, most of the people who +00:09:11.720 --> 00:09:13.380 +you know, most of the people who show up to
-show up to Emacs, especially talking about +00:09:13.380 --> 00:09:15.480 +Max Conf. Especially talking about stuff that
-stuff that has to do with presentations or +00:09:15.480 --> 00:09:18.160 +has to do with presentations or what they do
-what they do in academia, +00:09:18.260 --> 00:09:19.160 +in academia. You know,
-you know, they always say, +00:09:19.160 --> 00:09:20.520 +they always say, oh, but,
-oh, but, you know, I couldn't have done all +00:09:20.600 --> 00:09:22.589 +you know, I couldn't have done all this,
-this, you know, it's just far away. +00:09:22.589 --> 00:09:24.260 +you know, it's just far away.
+00:09:24.260 --> 00:09:26.320 And then they come back 1 year or 2 years
-later, and then, oh, I've made my entire +00:09:26.320 --> 00:09:27.980 +later and then, oh, I've made my entire
+00:09:27.980 --> 00:09:29.680 library for presentation and stuff like this.
+00:09:29.680 --> 00:09:32.980 So Be hopeful about what the future holds for
+00:09:32.980 --> 00:09:34.960 you in terms of coming up with crazy new
+00:09:34.960 --> 00:09:36.720 features for the entire ecosystem.
+00:09:37.740 --> 00:09:39.100 [Speaker 1]: Well, let me tell you,
+00:09:39.560 --> 00:09:42.540 since the pandemic, I have written,
+00:09:42.980 --> 00:09:44.760 I wrote my first major mode.
+00:09:44.760 --> 00:09:47.000 It's trivial, but it provides functionality
-that is very useful to me. +00:09:47.220 --> 00:09:52.660 +that is very useful to me and it's it's going
-And it's going to sound like I'm just trying +00:09:52.660 --> 00:09:54.380 +to sound like I'm just trying to butter
-to butter everyone up, +00:09:54.380 --> 00:09:57.260 +everyone up but seeing a lot of the names in
-but seeing a lot of the names in the IRC +00:09:57.260 --> 00:10:00.820 +the IRC channel people who have taught me so
-channel, people who have taught me so much on +00:10:00.820 --> 00:10:05.220 +much on their YouTube channels and in their
-their YouTube channels and in their blog +00:10:05.220 --> 00:10:07.920 +blog posts and on Reddit and on Mastodon.
-posts and on Reddit and on Mastodon. -
+00:10:09.600 --> 00:10:12.220 Without many of the people who are here today
+00:10:12.620 --> 00:10:15.300 watching my talk, it's very fun to have
+00:10:15.820 --> 00:10:18.160 people who have helped me learn so much about
+00:10:18.160 --> 00:10:20.140 Emacs. So thanks to all of you.
+00:10:21.580 --> 00:10:24.140 [Speaker 0]: Well, and yeah, and now you're becoming part
+00:10:24.140 --> 00:10:27.380 of this crew of people inspiring others to do
+00:10:27.380 --> 00:10:29.160 very much the same. So thank you for joining
+00:10:31.460 --> 00:10:32.520 [Speaker 1]: Thank you very much.
+00:10:29.160 --> 00:10:35.020 [Speaker 0]: the crew. Great. Moving on to the 2 last
+00:10:35.020 --> 00:10:36.660 questions and then we'll open up the mic to
-other people on BigBlueButton. +00:10:36.660 --> 00:10:38.340 +other people on Big Blue Button.
+00:10:39.160 --> 00:10:40.900 What kind of comparative feedback are
+00:10:40.900 --> 00:10:42.740 students giving you regarding your approach?
-[Speaker 1]: Oh my gosh. Students were ready to, -
-during the pandemic especially, +00:10:44.960 --> 00:10:48.340 +[Speaker 1]: Oh, my gosh. Students were ready to during
-when most of the courses were just being +00:10:48.340 --> 00:10:53.040 +the pandemic especially when most of the
-taught over Zoom by people sharing their +00:10:53.040 --> 00:10:55.880 +courses were just being taught over zoom by
-screens. +00:10:55.880 --> 00:10:57.340 +people sharing their screen.
-[Speaker 0]: Just a second, sorry, sorry for the +00:10:57.340 --> 00:10:58.660 +[Speaker 0]: Just a second. Sorry. Sorry for the
-interruption, very rude interruption, +00:10:58.660 --> 00:10:59.800 +interruption. Very rude interruption.
-but I've got the intro for the next talk +00:10:59.800 --> 00:11:01.220 +We've got the intro for the next talk playing
-playing and I'm not sure what's going on. +00:11:01.220 --> 00:11:02.520 +and I'm not sure what's going on.
+00:11:02.520 --> 00:11:03.580 Give me just a second.
-Sasha? +Sasha.
-So... Yeah, I think it's started. +00:11:05.060 --> 00:11:05.560 +[Speaker 1]: Okay.
-Sure. I got the times wrong, +00:11:19.320 --> 00:11:24.290 +Yeah, I think it's started.
-apparently, because of the little delay we +00:11:26.716 --> 00:11:31.740 +Okay so yeah I think it's not a
-had getting the audio fixed up. +00:11:34.860 --> 00:11:37.760 +[Speaker 0]: sure 1 I got the times wrong apparently
-The good news is that we're still recording +00:11:37.760 --> 00:11:40.240 +because of the little delay we had getting
-the talk right now and we still have James +00:11:40.240 --> 00:11:43.740 +the audio fixed up. The good news is that
-around. Obviously, James, +00:11:43.740 --> 00:11:45.880 +we're still recording the talk right now and
-you're no longer on being broadcast on +00:11:45.880 --> 00:11:47.140 +we still have James around.
-General, but if you want to keep answering +00:11:47.180 --> 00:11:49.740 +Obviously James you're no longer on being
-questions or if you want to, +00:11:49.740 --> 00:11:53.040 +broadcast on General but if you want to keep
-anyone in the room right now wants to ask you +00:11:53.040 --> 00:11:55.800 +answering questions or if you want to anyone
-questions, feel free to do so. +00:11:55.800 --> 00:11:57.340 +in the room right now wants to ask you
-I'm going to need to hop off because I need +00:11:57.340 --> 00:11:58.940 +questions feel free to do so.
-to get other things ready for the next talks, +00:11:59.440 --> 00:12:01.060 +I'm going to need to hop off because I need
-[Speaker 1]: But James, +00:12:01.060 --> 00:12:03.020 +to get other things ready for the next talks
-[Speaker 0]: sadly. great. And sorry, +00:12:04.280 --> 00:12:06.780 +[Speaker 1]: But James, thank you so much.
-I'm a little tense, obviously, +00:12:03.080 --> 00:12:10.020 +[Speaker 0]: sadly. Right and so sorry I'm a little tense
-because I was not expecting this to happen. +00:12:10.020 --> 00:12:12.660 +obviously because I was not expecting this to
-And that led to a very abrupt end to this +00:12:12.660 --> 00:12:15.960 +happen and that led to a very abrupt end to
-discussion. But people afterwards on +00:12:15.960 --> 00:12:18.480 +this discussion but people afterwards on
+00:12:18.480 --> 00:12:21.980 emacsmo.org slash 2023 slash talks will be
+00:12:21.980 --> 00:12:24.020 able to find all the content here.
+00:12:24.020 --> 00:12:25.420 So I'll have to leave now.
-Thank you so much, James, +00:12:25.840 --> 00:12:28.020 +Thank you so much James for doing the
-for doing the difficult task of opening up +00:12:28.020 --> 00:12:30.060 +difficult task of opening up EmacsConf and
-emacs-conf, And I'll probably see you later. +00:12:30.060 --> 00:12:31.980 +I'll probably see you later.
-[Speaker 1]: Thank you, Leo. Bye-bye. +00:12:32.780 --> 00:12:35.260 +[Speaker 1]: Thank you, Leo. Bye bye.
-[Speaker 3]: On your, the external, +00:12:52.020 --> 00:12:57.440 +[Speaker 2]: On your journal program.
-the journal You were, you, +00:12:58.360 --> 00:13:03.500 +Yes. You are using the tablet as a monitor,
-you were using the tablet as a monitor, +00:13:03.520 --> 00:13:05.940 +right? Touch screen monitor with that?
-right? Touchscreen monitor, +00:13:06.480 --> 00:13:08.800 +[Speaker 1]: That's exactly right. So it's a tablet so you
-what's that? +00:13:08.800 --> 00:13:11.980 +know I can. It has a touch screen and so.
-[Speaker 1]: program. Yes. That's exactly right. +00:13:13.080 --> 00:13:15.580 +So basically the functionality that that
-So it's a tablet, so it has a touchscreen. -
-And so basically the functionality that that -
+00:13:15.580 --> 00:13:20.580 program provides is to be able to just mark
+00:13:20.580 --> 00:13:22.160 up PDFs with a stylus,
+00:13:23.360 --> 00:13:25.280 you know, in the way that you would use any
+00:13:25.280 --> 00:13:30.600 other tablet. And to be able to take that
+00:13:30.600 --> 00:13:33.420 video signal and put it into another machine.
+00:13:33.840 --> 00:13:36.100 That was the that was the key.
+00:13:36.100 --> 00:13:37.340 That's the killer app.
-[Speaker 3]: I've thought about grabbing 1 for the purpose +00:13:39.340 --> 00:13:41.880 +[Speaker 2]: I've thought about grabbing 1 for the purpose
+00:13:41.940 --> 00:13:45.460 of like changing my laptop into a tablet to
-read manga, browse the web, +00:13:45.460 --> 00:13:49.640 +read manga, browse the web and kind of
-and I'm kind of curious if it works well like +00:13:49.640 --> 00:13:51.840 +curious if it works well like as a wireless
-as a wireless monitor with a tablet? +00:13:52.300 --> 00:13:57.440 +monitor with a tablet or how well it like you
-Or how well it like you can use Emacs with it +00:13:57.440 --> 00:14:01.920 +can use Emacs with it in a tablet mode or
-in a tablet mode? Or were you just or you +00:14:02.080 --> 00:14:03.000 +were you just
-just use +00:14:03.820 --> 00:14:10.800 +[Speaker 1]: or you just use the tablet that I use is this
-[Speaker 1]: the tablet that I use is this is it it's just +00:14:10.800 --> 00:14:14.340 +is it it's just a Microsoft Surface and so it
-the Microsoft Surface and so it comes with a +00:14:14.340 --> 00:14:17.780 +comes with a keyboard so you can take the
-keyboard So you can take the keyboard off. +00:14:17.780 --> 00:14:20.940 +keyboard off. Yeah, but I use it.
-But I use it with the keyboard as well. +00:14:20.940 --> 00:14:23.240 +I use it with the keyboard as well.
+00:14:24.560 --> 00:14:25.660 And I just.
-[Speaker 3]: You're cutting off right now. -
-Audio. -
-Your audio is cutting off right now. +00:14:30.060 --> 00:14:31.420 +[Speaker 2]: You're cutting off right now
-How about now? Now I can hear you. +00:14:53.880 --> 00:15:27.671 +[Speaker 1]: Audio Your audio is cutting off right now.
-[Speaker 1]: How about now? I bumped the mute button on +00:15:32.680 --> 00:15:34.580 +I bumped the mute button on the mic.
-the mic. Yeah, so again, +00:15:36.820 --> 00:15:38.300 +Yeah. So again, this is,
-this is... I'm trying to figure out which +00:15:38.500 --> 00:15:41.540 +[Speaker 2]: is the 16 mute buttons you use.
-[Speaker 3]: of the 16 mute buttons you used. +00:15:38.300 --> 00:15:45.660 +[Speaker 1]: this It's just the surface pro 3 that I got
-[Speaker 1]: It's just the Surface Pro 3 that I got used. +00:15:45.660 --> 00:15:48.920 +used and it runs Emacs.
-And it runs Emacs, I mean it runs GNU Linux +00:15:49.280 --> 00:15:54.300 +I mean it runs. You know Linux really well.
-really well. And the trouble is that the hard +00:15:54.940 --> 00:15:59.720 +And the trouble is that the hard drive you
-drive, you know, the SSD drive is small and +00:15:59.720 --> 00:16:02.920 +know the SSE drive is small and the RAM is
-the RAM is small, but it works for the +00:16:02.920 --> 00:16:06.920 +small, but it works for the purposes.
-purposes. Basically, if I had a couple +00:16:07.580 --> 00:16:10.080 +Basically, if I had a couple thousand
-thousand dollars, I could probably buy a +00:16:10.080 --> 00:16:13.860 +dollars, I could probably buy a touchscreen
-touch screen machine or I could run +00:16:14.280 --> 00:16:17.680 +machine where I could run everything on it
-everything on it and do the streaming and do +00:16:17.680 --> 00:16:21.360 +and do the streaming and do the video capture
-the video capture and do the PDF markup. +00:16:21.380 --> 00:16:25.460 +and do the PDF markup.
+00:16:26.020 --> 00:16:28.480 But since both of these are so,
+00:16:28.860 --> 00:16:31.980 the hardware that I use is so old and cheap
-and weak, I'd have to split it across 2 +00:16:31.980 --> 00:16:33.800 +and weak I have to split it across 2
+00:16:33.800 --> 00:16:34.300 machines.
-[Speaker 3]: There's also a beauty in making the stuff, +00:16:35.020 --> 00:16:37.660 +[Speaker 2]: There's also a beauty in making the stuff
+00:16:37.660 --> 00:16:40.080 having specific purposes for specific things
-where it's just not, yeah, +00:16:40.080 --> 00:16:46.020 +where it's just not. Yeah it's like I don't
-it's like, I don't want a smart TV that plays +00:16:46.020 --> 00:16:49.840 +want a smart TV that plays Netflix I want a
-Netflix. I want a Smart TV that has all the +00:16:50.140 --> 00:16:53.860 +smart TV that has all the smarts that I turn
-smarts that I turn my smart TV into a TV +00:16:53.860 --> 00:16:58.780 +my smart TV into a TV monitor I don't want to
-monitor. I +00:16:58.780 --> 00:16:59.280 +yeah
-[Speaker 1]: Don't want to yeah Really? +00:17:02.200 --> 00:17:08.539 +[Speaker 1]: I totally feel that ethic I totally I totally
-I I totally feel that ethic I totally feel +00:17:08.659 --> 00:17:11.640 +feel that ethic. Oh, on
-that ethic. +00:17:11.760 --> 00:17:15.300 +[Speaker 2]: the some other things like if you want you to
-[Speaker 3]: Oh, on the some other things, +00:17:15.300 --> 00:17:17.300 +do highlighting in an org mode document.
-like if you want you To do highlighting in an +00:17:17.300 --> 00:17:19.060 +You can use org web tools.
-org mode document you can use org web tools. +00:17:19.060 --> 00:17:20.020 +I wrote this in the notes,
-I wrote this in the notes But you can use org +00:17:20.020 --> 00:17:21.940 +but you can use org web tools to download a
-web tools to download a web page And then you +00:17:21.940 --> 00:17:25.400 +web page and then you can use org remark to
-can use org remark to start highlighting in +00:17:25.400 --> 00:17:28.860 +start highlighting in the org mode web page
-the org mode web page And then because it's +00:17:28.860 --> 00:17:30.860 +and then because an org mode document now you
-an org mode document now, +00:17:30.860 --> 00:17:32.180 +can just edit it directly.
-[Speaker 1]: right +00:17:35.600 --> 00:17:38.240 +If you want other people to join in on an
-[Speaker 3]: you can just edit it directly If you have If +00:17:38.240 --> 00:17:40.680 +Emacs session you could use a package like
-you want other people to join in on an emacs +00:17:40.680 --> 00:17:45.040 +what's it called? CRDT.EL
-session you could use a package like, +00:17:47.020 --> 00:17:50.160 +that will allow 2 people with 2 different
-what's it called, crdt.el -
-That will allow 2 people with 2 different -
+00:17:50.160 --> 00:17:52.820 Emacs configurations to edit the same buffer.
-What? And you have a host that can host a +00:17:54.140 --> 00:17:58.980 +And you have a host that can host a buffer
-[Speaker 1]: Interesting. +00:17:58.980 --> 00:18:05.960 +too. It works with, and they have 1 optional
-[Speaker 3]: buffer too. And they have 1 optional -
+00:18:06.000 --> 00:18:08.180 extension for org mode that will synchronize
+00:18:08.680 --> 00:18:10.600 the folding of the org drawers.
-[Speaker 1]: Interesting, I will look into that. -
-[Speaker 3]: Like having I don't like if you want students +00:18:12.320 --> 00:18:14.720 +[Speaker 1]: Interesting. I will look into that.
-like you have H highlight line mode. +00:18:15.060 --> 00:18:15.560 +Like
-These are just some ideas. +00:18:19.660 --> 00:18:22.720 +[Speaker 2]: having I don't like if you want students like
-It's like you can have like highlight line +00:18:22.720 --> 00:18:25.740 +you have each highlight line mode these are
-mode so people can easily see which line +00:18:25.740 --> 00:18:27.620 +just some ideas like you can have like
-you're on cursor tracking. +00:18:27.620 --> 00:18:30.060 +highlight line mode so people can easily see
-And then you can have other people join in, +00:18:30.060 --> 00:18:35.040 +which line you're on cursor tracking and then
-students, or yeah, that's just a possible +00:18:35.040 --> 00:18:38.680 +you can have other people join in students or
-idea. +00:18:43.180 --> 00:18:45.300 +[Speaker 1]: yeah that's just a possible idea.
-[Speaker 1]: Is there anyone else in the big blue button +00:18:45.300 --> 00:18:49.680 +Is there anyone else in the in the big blue
-room who has a question? +00:18:49.680 --> 00:18:52.180 +button room who has a question?
+00:19:01.360 --> 00:19:03.280 All right, I'm going to go over to the pad
+00:19:03.280 --> 00:19:05.280 and see if there are any pending questions I
-can address. Thanks PlasmaStrike. +00:19:05.280 --> 00:19:07.560 +can address. Thanks, Plasma Strike.
-Yep. +00:19:27.500 --> 00:19:33.140 +[Speaker 3]: Yep. Which could be PDF,
-[Speaker 2]: To be tangled into source code or woven into -
-a documentation file, which could be PDF, -
+00:19:33.340 --> 00:19:36.680 could be Markdown, could be OpenOffice,
+00:19:38.560 --> 00:19:40.100 could be a notebook format.
+00:19:40.960 --> 00:19:43.340 This methodology was conceived by Donald
+00:19:43.340 --> 00:19:51.980 Knuth in 1984. The main purpose of literal
+00:19:51.980 --> 00:19:54.700 programming is not only to make code or
+00:19:54.700 --> 00:19:57.220 documentation or output more manageable,
+00:19:57.800 --> 00:20:01.240 but to allow humans to create a data story to
-be pieced from a single source. +00:20:01.240 --> 00:20:03.420 +be used from a single source.
-What you see on the slide on the left hand +00:20:04.540 --> 00:20:06.300 +What you see on the slide on the left-hand
+00:20:06.300 --> 00:20:09.400 side is the story and code inside an org-mod
+00:20:09.400 --> 00:20:14.440 file. The file starts with some
-documentation, then you write back down the +00:20:14.440 --> 00:20:17.720 +documentation, then you write back down this
-code, and at the bottom you see an output +00:20:18.420 --> 00:20:22.060 +code, and at the bottom you see the output
+00:20:22.060 --> 00:20:26.540 file, which is not shown in the slide itself.
-In the middle, you have the source code, +00:20:26.800 --> 00:20:28.440 +In the middle you have the source code,
+00:20:28.440 --> 00:20:33.980 which is the result of tangling or opening a
+00:20:33.980 --> 00:20:36.880 buffer inside offload.
-On the very right-hand side, +00:20:37.660 --> 00:20:42.380 +On the very right hand side we have a PDF,
-we have a PDF. Actually, +00:20:42.580 --> 00:20:47.740 +actually this HTML, very same file that you
-this is HTML, random.org. +00:20:47.740 --> 00:20:48.960 +see in memory language.
-The very same file that you see in the memory +00:20:49.600 --> 00:20:53.080 +So the humans look at some of this code and
-language. So the humans look at some of this +00:20:53.080 --> 00:20:55.400 +the machines look at other parts of the code.
-code, and the machines look at other parts of +00:20:56.260 --> 00:20:58.320 +I actually did all my programming in the
-the code. I actually did all my programming +00:20:58.320 --> 00:21:00.260 +literary world even in the early 1990s,
-in the literate way even in the early 1990s, +00:21:00.920 --> 00:21:03.040 +not using Org Mode, which didn't exist yet,
-not using OrgMode, which didn't exist yet, +00:21:03.040 --> 00:21:06.160 +but using Norman Ramsey's Norep preprocessor.
-but using Norman Ramsey's NoWeb preprocessor. +00:21:07.240 --> 00:21:09.720 +They still use it inside the Org-Mode today.
-They still use it inside Org Mode today. +00:21:10.400 --> 00:21:11.920 +This preprocessor, Norep,
-This preprocessor, NoWeb, +00:21:11.920 --> 00:21:14.240 +allows you to tangle code from within an

-Mode file that is a self-standing file, +00:21:16.360 --> 00:21:18.820 +much like Org-mode's edit functions,
-much like Org Mode's edit functions, -
+00:21:19.540 --> 00:21:21.900 which export code blocks into buffers in
+00:21:21.900 --> 00:21:23.540 whatever language the code blocks.
+00:21:25.940 --> 00:21:28.760 In data science, these interactive notebooks,
-in 1 of the interpreted languages, -
-like Julia, Python, or R, +00:21:29.640 --> 00:21:32.776 +in 1 of the interpreted languages like Julia,
-dominate. The basic technology is that of +00:21:32.776 --> 00:21:34.680 +Python, or R dominating?
-Jupyter notebooks, which take their name from +00:21:34.680 --> 00:21:37.420 +The basic technology is that of Jupyter
-Julia, Python, and R. And these notebooks use +00:21:37.420 --> 00:21:39.840 +notebooks, which take their name from Julia,
-a spruce-stuffed shell, +00:21:39.860 --> 00:21:43.040 +Python, and R. And these notebooks use a
-for example, IPython, and an option to add +00:21:43.040 --> 00:21:44.880 +spruce-dark shell, for example,
-SQL cells. Alt mode inside Emacs has a large +00:21:44.920 --> 00:21:49.240 +IPython, and an option to add SQL cells.

+00:22:06.460 --> 00:22:07.700 While in Jupyter notebooks,
+00:22:07.920 --> 00:22:10.900 a notebook is limited to running a kernel in
+00:22:10.900 --> 00:22:14.440 1 language only. The content of the notebook,

-can be exported in a variety of forms. -
