WEBVTT 00:00:03.639 --> 00:00:04.140 [Speaker 0]: Again, second only live Q&A of the day. 00:00:05.980 --> 00:00:06.339 So, things are still a bit rusty, 00:00:07.859 --> 00:00:08.360 but believe me, by the end of the morning, 00:00:11.719 --> 00:00:12.219 we will be well-oiled machinery. 00:00:13.440 --> 00:00:13.940 So, hi Marcus, how are you doing? 00:00:15.360 --> 00:00:15.860 [Speaker 1]: I'm fine, Thank you. 00:00:19.900 --> 00:00:20.020 [Speaker 0]: I really liked, most people might have 00:00:21.680 --> 00:00:22.180 forgotten, but you started your presentation 00:00:25.840 --> 00:00:26.340 with the, in a very dark room and with this 00:00:29.200 --> 00:00:29.340 typical note of dry German humor that I 00:00:30.400 --> 00:00:30.900 particularly liked. 00:00:33.900 --> 00:00:34.280 [Speaker 1]: Whereas I told you we're born without humour 00:00:38.040 --> 00:00:38.300 so any sense of humour is the result of very 00:00:38.559 --> 00:00:39.059 hard work. 00:00:43.840 --> 00:00:44.280 [Speaker 0]: Well I can confirm therefore that your work 00:00:46.100 --> 00:00:46.600 is evident in this particular remark. 00:00:50.379 --> 00:00:50.879 So as we did before and perhaps this time 00:00:53.940 --> 00:00:54.320 more punctiliously, terrible adverb, 00:00:57.660 --> 00:00:58.100 that's why I'm an English major we will be 00:01:00.220 --> 00:01:00.420 taking questions first from the pad and then 00:01:03.420 --> 00:01:03.740 we'll be moving on to people in the BBV room. 00:01:05.200 --> 00:01:05.540 Let me just check if we have some people. 00:01:06.220 --> 00:01:06.720 We do have some people. 00:01:08.720 --> 00:01:08.860 All right, so Markus, I'm gonna ask you the 00:01:11.120 --> 00:01:11.200 questions in the pad unless you have 00:01:12.100 --> 00:01:12.600 something to remark first. 00:01:15.040 --> 00:01:15.060 [Speaker 1]: Yes, oh no, no, I don't have nothing to 00:01:17.680 --> 00:01:17.800 remark. I mean, only that we're coming to the 00:01:19.940 --> 00:01:20.200 end of the term here, and I think in the 00:01:23.920 --> 00:01:24.140 paper that I wrote, I expressed doubt that 00:01:25.080 --> 00:01:25.560 Emacs was good for beginners, 00:01:31.220 --> 00:01:31.720 but I've now gone back to an interactive 00:01:33.520 --> 00:01:34.020 notebook in the class without Emacs, 00:01:37.280 --> 00:01:37.500 and I've just missed it terribly the whole 00:01:38.940 --> 00:01:39.220 term. And I think I saw you walk too, 00:01:40.040 --> 00:01:40.540 so that's kind of interesting. 00:01:41.660 --> 00:01:42.160 That's it. 00:01:43.320 --> 00:01:43.580 [Speaker 0]: Right. All right, well, 00:01:44.860 --> 00:01:45.040 let's get started with the questions because 00:01:47.440 --> 00:01:47.940 I'm a little worried that we might acquire 00:01:50.140 --> 00:01:50.580 debt because of the time that we have. 00:01:52.900 --> 00:01:53.040 And just to be clear, so that you also know 00:01:54.360 --> 00:01:54.479 the time at which we're supposed to be 00:01:56.979 --> 00:01:57.240 finishing, the next talk here on this track 00:01:59.060 --> 00:01:59.560 is supposed to be at 10.40, 00:02:01.240 --> 00:02:01.740 which is in 13 minutes from now. 00:02:02.720 --> 00:02:03.220 All right, with that said, 00:02:04.000 --> 00:02:04.500 starting with the first questions. 00:02:06.820 --> 00:02:07.300 What tools do you use for making your slides? 00:02:08.940 --> 00:02:09.440 They are very nice and I concur. 00:02:17.680 --> 00:02:18.180 OrgReveal? 00:02:22.100 --> 00:02:22.600 [Speaker 1]: I use OrgReveal. It's a package, 00:02:26.100 --> 00:02:26.380 OrgReveal. I don't have the link right now, 00:02:31.160 --> 00:02:31.560 but it's an org mode package where You create 00:02:35.220 --> 00:02:35.400 some meta information and I think it's 00:02:39.660 --> 00:02:39.900 basically JavaScript, JavaScript package that 00:02:41.120 --> 00:02:41.620 will work from a bunch of different 00:02:49.300 --> 00:02:49.540 platforms, but it works particularly well 00:02:51.620 --> 00:02:52.120 from Emacs. So you use that a lot. 00:02:55.080 --> 00:02:55.440 [Speaker 0]: Right, yeah, I think it is definitely 00:02:56.720 --> 00:02:57.120 interacting with JavaScript in the background 00:02:58.620 --> 00:02:59.120 and it makes for a very clean presentation 00:03:01.240 --> 00:03:01.380 right from Emacs. I mean, 00:03:04.180 --> 00:03:04.340 it's not opened in Emacs unless you use a web 00:03:06.180 --> 00:03:06.480 browser in Emacs that supports such 00:03:09.280 --> 00:03:09.400 compositing but it's pretty convenient and I 00:03:10.280 --> 00:03:10.780 recommend looking into it. 00:03:19.040 --> 00:03:19.540 [Speaker 1]: I'm just going to share the URL here. 00:03:20.900 --> 00:03:21.400 So if anybody's interested. 00:03:23.800 --> 00:03:24.140 [Speaker 0]: Right, and we'll be putting all the links 00:03:25.440 --> 00:03:25.600 right now. So obviously right now, 00:03:27.740 --> 00:03:28.180 Marcus is writing inside of his own Emacs, 00:03:28.940 --> 00:03:29.340 but we also have the pad. 00:03:30.760 --> 00:03:31.020 We'll make sure that you have all the links 00:03:32.020 --> 00:03:32.520 accessible a little bit later. 00:03:33.840 --> 00:03:34.340 Okay, moving on to the next question, 00:03:34.860 --> 00:03:35.360 why MDPI? 00:03:40.140 --> 00:03:40.520 [Speaker 1]: Oh yeah, well that's a little bit of a longer 00:03:42.100 --> 00:03:42.600 answer, kind of boring I suppose. 00:03:44.180 --> 00:03:44.680 So when I came here to the US, 00:03:47.800 --> 00:03:47.960 I used to teach a lot of graduate courses and 00:03:49.160 --> 00:03:49.280 I had to suddenly teach a lot of 00:03:49.960 --> 00:03:50.460 undergraduate courses, 00:03:52.940 --> 00:03:53.100 which partly motivated this move because it 00:03:55.520 --> 00:03:55.640 made me realize, as I said in the 00:03:57.660 --> 00:03:58.020 presentation, how little the students 00:03:59.280 --> 00:03:59.780 understand of the underlying infrastructure 00:04:01.760 --> 00:04:01.920 and how important it is for them to work with 00:04:05.940 --> 00:04:06.440 an IDE that doesn't make coding especially 00:04:09.020 --> 00:04:09.140 convenient, but that teaches them a lot of 00:04:10.400 --> 00:04:10.840 the stuff on the side, 00:04:12.580 --> 00:04:13.080 you know, while still presenting a very 00:04:16.880 --> 00:04:17.380 smooth environment, which developers 00:04:21.899 --> 00:04:22.120 appreciate as well. So I came here and I used 00:04:24.320 --> 00:04:24.520 to publish like 4 or 5 research papers per 00:04:25.640 --> 00:04:26.140 year, but I didn't have the time. 00:04:28.260 --> 00:04:28.760 So I was contacted by MDPI. 00:04:33.840 --> 00:04:34.340 And it's 1 of those research paper mills, 00:04:36.660 --> 00:04:37.160 which seem to be springing up where authors 00:04:40.600 --> 00:04:40.840 can, really the institutions of the authors 00:04:42.100 --> 00:04:42.560 have to pay so that they can publish, 00:04:43.940 --> 00:04:44.440 right? So it's not really, 00:04:46.160 --> 00:04:46.400 and I checked them out and they seem to be 00:04:47.260 --> 00:04:47.680 proper peer review publishing, 00:04:48.900 --> 00:04:49.120 but to be absolutely sure I said, 00:04:49.960 --> 00:04:50.460 well, you can have my article, 00:04:52.120 --> 00:04:52.540 but of course for free, 00:04:54.640 --> 00:04:55.080 I'm not going to pay for you to publish it. 00:04:57.200 --> 00:04:57.700 And so that's what they did. 00:05:01.060 --> 00:05:01.160 They invited me and I submitted the paper and 00:05:01.920 --> 00:05:02.240 it was a very good process. 00:05:04.280 --> 00:05:04.540 That was a very, it was a good peer review 00:05:06.400 --> 00:05:06.760 critique. So I changed the paper quite a bit. 00:05:07.640 --> 00:05:07.940 It's still not a great paper. 00:05:09.060 --> 00:05:09.320 It's just a small case study. 00:05:11.880 --> 00:05:12.100 That's the kind of thing that you have a lot 00:05:14.580 --> 00:05:14.800 in medical research where also people don't 00:05:17.280 --> 00:05:17.720 have a lot of time to do research, 00:05:19.280 --> 00:05:19.480 proper research, which takes a very long 00:05:21.020 --> 00:05:21.520 time. And so that's why MDPI. 00:05:24.160 --> 00:05:24.660 And they are in the most of the relevant 00:05:27.280 --> 00:05:27.780 citation indices. So they are reputable 00:05:30.700 --> 00:05:30.920 enough. I mean, normally I would say for 00:05:32.560 --> 00:05:33.060 anybody who does anything like this, 00:05:36.200 --> 00:05:36.420 you might not even want to bother with the 00:05:37.260 --> 00:05:37.640 journal these days anymore. 00:05:38.760 --> 00:05:39.260 You just go straight to ArcSci, 00:05:41.120 --> 00:05:41.620 put out your preprint. 00:05:44.380 --> 00:05:44.540 And in fact, what will happen if you're on 00:05:46.000 --> 00:05:46.440 ArcSci, if somebody finds it interesting, 00:05:49.400 --> 00:05:49.900 they're going to reach out to you to capture 00:05:54.000 --> 00:05:54.280 your paper and have it published under their 00:05:55.800 --> 00:05:56.120 heading. Oh yeah, actually the other reason 00:05:58.260 --> 00:05:58.660 why I wanted MDPI is because there were open 00:05:59.480 --> 00:05:59.980 access from the start. 00:06:02.360 --> 00:06:02.660 And I really like, if you go to the paper, 00:06:03.820 --> 00:06:04.200 I really like the way it's presented. 00:06:07.120 --> 00:06:07.340 So I looked at a few papers and I thought 00:06:11.640 --> 00:06:12.140 it's a really nice online access, 00:06:13.480 --> 00:06:13.980 online open access solution. 00:06:16.720 --> 00:06:17.220 That's the long answer, 00:06:17.220 --> 00:06:17.720 sorry. 00:06:20.660 --> 00:06:21.060 [Speaker 0]: No, that was perfectly fine and you provided 00:06:23.400 --> 00:06:23.760 many details so it was far from a boring 00:06:24.920 --> 00:06:25.420 answer, let me reassure you. 00:06:26.820 --> 00:06:27.100 Moving on to the question, 00:06:28.900 --> 00:06:29.120 we only have about 8 minutes left so I'd like 00:06:31.360 --> 00:06:31.500 to finish those 2 questions and let people in 00:06:33.960 --> 00:06:34.460 the audience speak. So do you think immersion 00:06:37.060 --> 00:06:37.500 can be achieved on teaching other students 00:06:38.100 --> 00:06:38.600 with different backgrounds? 00:06:41.680 --> 00:06:42.180 [Speaker 1]: Oh yeah, that's a really good question. 00:06:48.160 --> 00:06:48.380 I had actually a discussion last night with 00:06:49.680 --> 00:06:49.920 my wife in bed about this, 00:06:52.360 --> 00:06:52.860 about the use of textbooks which are famously 00:06:55.560 --> 00:06:55.840 non-immersive because they're consumed away 00:06:58.140 --> 00:06:58.640 from the class. Very rarely you sit in class 00:07:00.100 --> 00:07:00.540 like people used to do and read something 00:07:01.960 --> 00:07:02.420 together. Maybe they did that in English. 00:07:04.200 --> 00:07:04.700 And that is of course instantly immersive. 00:07:06.300 --> 00:07:06.700 But in computer science, 00:07:07.680 --> 00:07:08.180 many other topics, psychology, 00:07:09.800 --> 00:07:10.300 you know, biology and so on, 00:07:11.820 --> 00:07:12.260 you cannot get immersion, 00:07:13.740 --> 00:07:14.240 at least not in a lecture theater. 00:07:16.760 --> 00:07:16.960 You get it in a lab because people solve the 00:07:18.480 --> 00:07:18.920 problem and then they're immersed in it. 00:07:20.500 --> 00:07:20.680 So, but my answer would be, 00:07:22.580 --> 00:07:22.680 yes, I can think totally immersion can be 00:07:25.260 --> 00:07:25.540 achieved anywhere, but what you have to do is 00:07:29.180 --> 00:07:29.500 you have to not lecture and you have to let 00:07:31.280 --> 00:07:31.640 students do work as you go along. 00:07:33.680 --> 00:07:33.840 So I used to lecture quite a bit because I 00:07:38.000 --> 00:07:38.220 was an insecure young professor and just read 00:07:41.120 --> 00:07:41.400 all my slides and my notes as I used to use, 00:07:43.040 --> 00:07:43.540 as everybody uses to when they start. 00:07:45.660 --> 00:07:46.100 But as I went along, I realized, 00:07:47.860 --> 00:07:48.240 you know, I've got such a grasp of the topic 00:07:50.660 --> 00:07:51.080 that I really everything I do now is prepared 00:07:53.220 --> 00:07:53.720 in Emacs in an interactive way so I start 00:07:55.120 --> 00:07:55.480 saying a few words and then the students 00:07:57.840 --> 00:07:58.000 immediately we get to work and they seem to 00:07:59.640 --> 00:07:59.840 love that because in most of the other 00:08:01.460 --> 00:08:01.680 classes people just talk at them they take 00:08:03.000 --> 00:08:03.500 their stuff home and work at home, 00:08:04.640 --> 00:08:05.140 which is of course is super. 00:08:06.220 --> 00:08:06.680 But most of the students, 00:08:08.320 --> 00:08:08.600 if they have, in at least in a liberal arts 00:08:09.720 --> 00:08:10.220 college, they have 5 other classes, 00:08:13.200 --> 00:08:13.520 they do not take a lot of time to do the work 00:08:16.389 --> 00:08:16.880 at home. So it's, you know, 00:08:18.420 --> 00:08:18.840 yeah, It's kind of different. 00:08:19.820 --> 00:08:20.020 It's kind of risky, yeah, 00:08:22.040 --> 00:08:22.360 but the main point I was trying to make is 00:08:26.320 --> 00:08:26.740 Emacs and Org Mode really helped me to boil 00:08:28.780 --> 00:08:29.220 that interactive session down to something 00:08:30.320 --> 00:08:30.800 that will work in the classroom. 00:08:32.080 --> 00:08:32.559 I don't have to jump around between 00:08:33.240 --> 00:08:33.740 platforms. For example, 00:08:35.659 --> 00:08:35.799 this term, and I didn't use Emacs in the 00:08:36.419 --> 00:08:36.919 class with the students, 00:08:39.740 --> 00:08:40.240 I had to render using a package. 00:08:42.169 --> 00:08:42.299 It's actually a very nice package called, 00:08:45.620 --> 00:08:46.100 what's it called? Ox, what's it called? 00:08:50.020 --> 00:08:50.520 Ox, Ox IPNB. It's called Ox IPNB. 00:08:53.000 --> 00:08:53.360 So what it does is it renders in the usual 00:08:55.080 --> 00:08:55.580 way with Emacs, Org Mode does, 00:08:58.580 --> 00:08:58.700 renders interactive notebook files in 00:09:00.560 --> 00:09:01.060 Jupyter. And that took me a lot of time. 00:09:03.700 --> 00:09:03.840 And I immediately noticed as soon as the 00:09:05.680 --> 00:09:06.180 teacher has to fight platforms themselves, 00:09:09.520 --> 00:09:09.920 they take the ball off the immersion task, 00:09:11.840 --> 00:09:12.340 you know, to keep the student on the problem. 00:09:18.060 --> 00:09:18.560 [Speaker 0]: Yeah. Oh, go on, please. 00:09:22.340 --> 00:09:22.840 Yeah. I was going to remark that. 00:09:22.840 --> 00:09:23.260 [Speaker 1]: So yeah, absolutely. Yeah, 00:09:24.760 --> 00:09:25.120 I suppose it might be MIT style. 00:09:25.760 --> 00:09:26.140 Big difference though, 00:09:27.620 --> 00:09:27.900 my classes are very, very short, 00:09:29.720 --> 00:09:30.060 small. So I have like between 10 and 15 00:09:32.080 --> 00:09:32.180 students per class. 1 of the reasons why I 00:09:34.800 --> 00:09:35.080 went to this college is because I was fed up 00:09:36.740 --> 00:09:36.940 teaching, trying to teach hundreds of 00:09:40.120 --> 00:09:40.580 students. Okay, sorry, 00:09:42.240 --> 00:09:42.520 do some of your students nag you about using 00:09:43.260 --> 00:09:43.460 VS Code? Yes, they do, 00:09:44.800 --> 00:09:45.300 but their arguments aren't very good. 00:09:48.420 --> 00:09:48.740 They hadn't really compared Emacs and VS 00:09:51.300 --> 00:09:51.800 Code. And what I do, actually I use RStudio 00:09:53.560 --> 00:09:53.860 as well, demonstrate VS Code, 00:10:00.840 --> 00:10:01.060 RStudio and Emacs. And I think it's very easy 00:10:02.440 --> 00:10:02.840 for them to see. And there are some videos 00:10:04.900 --> 00:10:05.020 about that as well, how much easier it is to 00:10:08.320 --> 00:10:08.520 get into Emacs to limit your investments to 00:10:09.520 --> 00:10:09.820 what you actually wanna do. 00:10:11.680 --> 00:10:11.840 When the problem with VS Code is it comes at 00:10:13.780 --> 00:10:14.280 you with this sort of Microsoft store 00:10:16.780 --> 00:10:17.280 ideology, like a gazillion plugins, 00:10:18.340 --> 00:10:18.840 which if you're a developer, 00:10:19.640 --> 00:10:20.140 you know what you want. 00:10:23.620 --> 00:10:24.120 And I mean, it's a bit like VS Code is like 00:10:27.440 --> 00:10:27.940 Google search for as if you were programming 00:10:30.320 --> 00:10:30.820 in Google search, a complete waste of time. 00:10:32.920 --> 00:10:33.280 Having said that, I've also seen some videos 00:10:35.900 --> 00:10:36.180 with people who really know how to use VS 00:10:37.040 --> 00:10:37.420 Code. And of course, you know, 00:10:40.940 --> 00:10:41.180 if somebody gets on the inside of a tool and 00:10:44.340 --> 00:10:44.480 spends upwards of a thousand hours in the 00:10:45.340 --> 00:10:45.840 tool, they'll be great. 00:10:47.080 --> 00:10:47.580 But that's not true for beginners. 00:10:50.280 --> 00:10:50.780 So hold on, there's another 1. 00:10:51.820 --> 00:10:52.320 I'm reading them, sorry. 00:10:54.920 --> 00:10:55.420 Leo, I can see the questions, 00:10:57.500 --> 00:10:58.000 but you may wanna turn them around. 00:11:00.520 --> 00:11:00.720 [Speaker 0]: No, No, no, please, please, 00:11:01.320 --> 00:11:01.560 you're free to read them. 00:11:02.400 --> 00:11:02.900 I'm on your fasted computer. 00:11:04.200 --> 00:11:04.600 [Speaker 1]: Some of you, too, that's the nagging. 00:11:05.660 --> 00:11:06.100 I teach simple programming at a vocational 00:11:07.360 --> 00:11:07.700 school, and even after showing the students 00:11:09.060 --> 00:11:09.520 Vim, Vim, of course, is a contender, 00:11:10.760 --> 00:11:11.260 and now I'm telling them I prefer Emacs. 00:11:14.060 --> 00:11:14.260 They still all choose VS Code as their 00:11:16.960 --> 00:11:17.460 editor. Well, okay, what I did is mandatory. 00:11:18.640 --> 00:11:19.140 I didn't let them choose. 00:11:21.740 --> 00:11:21.980 That's what I did. And I thought that was 00:11:23.300 --> 00:11:23.800 quite risky, but in the end, 00:11:26.140 --> 00:11:26.400 it turns out that the best students loved it 00:11:28.080 --> 00:11:28.580 and keep using Emacs in their jobs. 00:11:32.140 --> 00:11:32.640 I hear that now. The students in the middle 00:11:35.640 --> 00:11:35.860 were probably the ones who would pick VS Code 00:11:37.900 --> 00:11:38.400 because every tutorial they see, 00:11:40.240 --> 00:11:40.440 they learn a lot through YouTube and so 00:11:41.760 --> 00:11:42.260 everything they see is in VS Code. 00:11:43.780 --> 00:11:44.180 If there were more tutorials in Emacs, 00:11:45.100 --> 00:11:45.600 I'm trying to make some, 00:11:47.120 --> 00:11:47.620 then of course that would be different. 00:11:53.720 --> 00:11:53.940 But I think it's partly brainwashing and 00:11:55.680 --> 00:11:55.840 partly, of course, the other reason is there 00:11:59.820 --> 00:12:00.320 is no online Emacs. They use VS Code Dev, 00:12:01.960 --> 00:12:02.460 right? And that's, of course, 00:12:04.640 --> 00:12:05.140 they use an online cloud solution. 00:12:06.820 --> 00:12:07.040 Like most of the students in the high school, 00:12:08.860 --> 00:12:09.360 I teach Python in the high school right now, 00:12:11.460 --> 00:12:11.600 and the students only get Chromebooks that 00:12:13.660 --> 00:12:14.160 are completely cut down to nothing. 00:12:16.920 --> 00:12:17.420 They cannot have Linux on their Chromebooks. 00:12:19.540 --> 00:12:19.900 So what are they supposed to do? 00:12:21.080 --> 00:12:21.580 Their only choice really is Repl. 00:12:24.060 --> 00:12:24.240 Repl.com is a possibility for them to do 00:12:27.040 --> 00:12:27.540 that. But, you know, or they use code spaces, 00:12:29.060 --> 00:12:29.560 which is VS Code in GitHub. 00:12:32.300 --> 00:12:32.660 [Speaker 0]: Marcus, sorry for the interruption. 00:12:33.820 --> 00:12:34.040 We only have about 2 minutes left. 00:12:35.140 --> 00:12:35.380 So if you could take 1 question, 00:12:36.260 --> 00:12:36.760 that would be great. Sorry. 00:12:37.800 --> 00:12:38.100 [Speaker 1]: So. I'm observing the same behavior. 00:12:39.620 --> 00:12:40.080 Any more tutorials will be most welcome. 00:12:43.260 --> 00:12:43.660 Yes, I I'd love to. I spent the rest of my 00:12:45.980 --> 00:12:46.100 days on this earth making Emacs tutorials if 00:12:49.016 --> 00:12:49.267 [Speaker 0]: tutorials if I can. 00:12:49.518 --> 00:12:49.769 [Speaker 1]: I can. Thank you. DMAX Thank you. 00:12:50.540 --> 00:12:51.040 Approach to handling EDA. 00:12:52.200 --> 00:12:52.700 Oh yeah, with white data sets. 00:12:58.440 --> 00:12:58.940 Well, that's a good point. 00:13:03.080 --> 00:13:03.260 [Speaker 0]: So Markus, I don't want to put you under too 00:13:06.180 --> 00:13:06.680 [Speaker 1]: answer the question. The handling EDA, 00:13:08.460 --> 00:13:08.760 I don't know, if you look at the comments, 00:13:09.560 --> 00:13:09.960 I think these are on YouTube, 00:13:10.840 --> 00:13:11.340 right, at some point, Leo? 00:13:12.380 --> 00:13:12.600 [Speaker 0]: much pressure to Oh yes, 00:13:13.580 --> 00:13:13.860 they will definitely be on YouTube. 00:13:14.440 --> 00:13:14.540 answer the 00:13:15.420 --> 00:13:15.580 [Speaker 1]: I'm going to question you asked about the 00:13:17.360 --> 00:13:17.560 EDA, that's too long to go into right now, 00:13:20.740 --> 00:13:21.100 plus my cat is here. So I'm going to answer 00:13:22.120 --> 00:13:22.620 that in the comments, all right? 00:13:23.660 --> 00:13:24.160 Start up the conversation. 00:13:27.400 --> 00:13:27.800 Yes, I'm going to post that in the comments 00:13:27.980 --> 00:13:28.480 as well. 00:13:31.120 --> 00:13:31.500 [Speaker 0]: Sure, but Also, just to be clear, 00:13:32.480 --> 00:13:32.640 Marcus, you're going to continue the 00:13:35.320 --> 00:13:35.440 discussion. It's just a stream that will be 00:13:36.880 --> 00:13:37.160 moving on to the next talk in about 50 00:13:39.000 --> 00:13:39.380 seconds. Marcus, feel free to keep answering 00:13:40.360 --> 00:13:40.760 questions inside this room. 00:13:42.280 --> 00:13:42.780 You also have people, we're going to check 00:13:44.240 --> 00:13:44.540 aside with the stream, 00:13:46.000 --> 00:13:46.280 we have a number of people in the room. 00:13:47.800 --> 00:13:48.300 You can see them on the left on the button 00:13:50.860 --> 00:13:51.360 who are probably going to unmute themselves 00:13:52.080 --> 00:13:52.580 and ask you questions. 00:13:53.940 --> 00:13:54.440 So feel free to stay in the room, 00:13:56.680 --> 00:13:57.100 answer as lengthy as you want the questions 00:13:58.520 --> 00:13:58.700 because that's more content for us and we 00:14:01.360 --> 00:14:01.640 love it obviously. But it's just that I 00:14:03.640 --> 00:14:03.760 personally will be leaving to take care of 00:14:04.360 --> 00:14:04.860 the rest of the talks. 00:14:06.660 --> 00:14:06.880 So, Markus, do you have any last words before 00:14:07.240 --> 00:14:07.740 we move on? 00:14:09.240 --> 00:14:09.680 [Speaker 1]: No, just thank you for this wonderful... 00:14:10.580 --> 00:14:11.080 I'm going to copy this. 00:14:13.100 --> 00:14:13.280 I don't think I listened to the talk by 00:14:15.040 --> 00:14:15.200 Sascha yet, but I'm going to do that because 00:14:17.720 --> 00:14:18.080 I really want to copy this conference format. 00:14:19.740 --> 00:14:19.860 I think that is the conference format of the 00:14:21.420 --> 00:14:21.820 future, using volunteers to put together 00:14:22.860 --> 00:14:23.100 conferences. So I can't wait. 00:14:24.560 --> 00:14:24.720 Nobody wants to come to Batesville where I 00:14:25.600 --> 00:14:25.840 am, but thank you so much. 00:14:26.680 --> 00:14:27.180 That was really super professional. 00:14:27.540 --> 00:14:28.040 I love that. 00:14:31.920 --> 00:14:32.420 [Speaker 0]: Great. Okay, we are almost perfectly on time. 00:14:35.080 --> 00:14:35.420 I think we caught up about 1 or 2 seconds 00:14:36.820 --> 00:14:37.200 into the last sentence you said but otherwise 00:14:38.800 --> 00:14:38.960 we were splendidly on time. 00:14:39.760 --> 00:14:40.260 So thank you so much Marcus. 00:14:42.940 --> 00:14:43.140 [Speaker 1]: You're welcome. So I wanted to say a little 00:14:46.160 --> 00:14:46.660 bit about that question about handling EDA. 00:14:52.680 --> 00:14:52.960 [Speaker 0]: Can you see the chat on the left? 00:14:54.220 --> 00:14:54.720 Because people have started asking questions 00:14:55.680 --> 00:14:56.180 on the left. Can you see the chat? 00:14:56.366 --> 00:14:56.866 [Speaker 1]: I mean I used email. Sorry, 00:15:00.320 --> 00:15:00.820 [Speaker 0]: So you've got multiple avenues for questions. 00:15:01.093 --> 00:15:01.166 [Speaker 2]: You can 00:15:01.880 --> 00:15:02.380 [Speaker 0]: still answer questions in the chat. 00:15:03.540 --> 00:15:03.760 [Speaker 1]: sorry, sorry. Okay, I'm just going to go into 00:15:04.740 --> 00:15:05.240 that. Yeah, that's fine. 00:15:06.420 --> 00:15:06.760 [Speaker 0]: Sure, I'll need to go now. 00:15:08.260 --> 00:15:08.560 So Marcus, have a great day and I'll probably 00:15:08.860 --> 00:15:09.360 see you later. NOTE Start of section to review 00:15:11.780 --> 00:15:12.280 [Speaker 1]: Yeah, thank you. Sorry. 00:15:15.200 --> 00:15:15.620 Bye bye. There was a question about the, 00:15:17.280 --> 00:15:17.560 I wanted to ask the answer the question about 00:15:21.380 --> 00:15:21.760 EDA, large data sets. So, 00:15:24.160 --> 00:15:24.660 I mean, I teach undergraduate now, 00:15:27.600 --> 00:15:28.100 so there's a limited number of courses, 00:15:32.100 --> 00:15:32.360 like where I use, actually have big data 00:15:35.860 --> 00:15:36.100 issues. And I mean I'm not saying that I'm 00:15:38.480 --> 00:15:38.760 not that I don't run into performance issues 00:15:40.080 --> 00:15:40.580 with Emacs. I obviously do. 00:15:43.380 --> 00:15:43.680 But like the performance issues in Emacs are 00:15:45.440 --> 00:15:45.780 comparable to performance issues for example 00:15:49.080 --> 00:15:49.580 when using R. In R everything is in memory So 00:15:52.200 --> 00:15:52.700 you are limited to the available, 00:15:55.840 --> 00:15:56.020 what is it, 2 gigabyte or whatever memory of 00:15:57.720 --> 00:15:58.180 your computer. So you would have to find 00:15:59.860 --> 00:16:00.360 other infrastructure solutions anyway. 00:16:05.540 --> 00:16:05.860 The advantage of using Emacs is that I can, 00:16:07.120 --> 00:16:07.620 within 1 Org Mode file, 00:16:09.780 --> 00:16:10.280 connect to an external database. 00:16:13.440 --> 00:16:13.840 I can even, as probably most of you know, 00:16:17.500 --> 00:16:17.860 I can even use it as a text-based web browser 00:16:20.140 --> 00:16:20.640 if I want to. So I could look at individual 00:16:26.320 --> 00:16:26.780 files. And the other point of EDA of course 00:16:30.480 --> 00:16:30.640 is that you're not supposed to look at the 00:16:32.760 --> 00:16:33.260 tables. You're supposed to get the basic 00:16:40.800 --> 00:16:41.300 frame of your data. Is there a header? 00:16:43.540 --> 00:16:43.780 What's the approximate size and stuff like 00:16:45.720 --> 00:16:45.980 that? And then you're supposed to import it 00:16:47.080 --> 00:16:47.580 into a data frame ideally, 00:16:50.760 --> 00:16:51.260 at least in portions. And I don't think, 00:16:56.040 --> 00:16:56.260 yeah, so that's it. But the full answer is 00:16:59.720 --> 00:16:59.980 that I have not done big data analysis in 00:17:01.780 --> 00:17:02.280 Emacs. So that's actually a really nice 00:17:05.900 --> 00:17:06.099 extension. I'm going to write that down as a 00:17:07.900 --> 00:17:08.260 thing to talk about in some future talk. 00:17:10.319 --> 00:17:10.819 Okay, so ADA with big data. 00:17:13.579 --> 00:17:13.940 Even though interesting would be to know what 00:17:16.160 --> 00:17:16.560 kind of size of data you're actually talking 00:17:18.800 --> 00:17:19.300 about. So I don't know, 00:17:25.740 --> 00:17:25.940 what is it, upwards of 1 terabyte or 00:17:27.099 --> 00:17:27.520 something like that, I don't know. 00:17:28.520 --> 00:17:29.020 That'd be interesting to know. 00:17:34.440 --> 00:17:34.940 Haven't done that in class. 00:17:39.960 --> 00:17:40.460 So there's another question. 00:17:42.840 --> 00:17:43.020 Proportion of students that you think would 00:17:44.480 --> 00:17:44.820 keep on using Emacs after your course? 00:17:45.660 --> 00:17:46.000 That's not a difficult question, 00:17:47.440 --> 00:17:47.880 because as I said, I have very small classes. 00:17:48.760 --> 00:17:49.200 I've been here since 2 years. 00:17:51.040 --> 00:17:51.540 So I'm in touch with almost all the students. 00:17:54.280 --> 00:17:54.760 In fact, I'm getting them work after school. 00:17:55.480 --> 00:17:55.980 So that's really cool. 00:18:00.160 --> 00:18:00.660 And everybody who took to Emacs really 00:18:03.540 --> 00:18:03.900 seriously, so probably about 25% or so keep 00:18:05.660 --> 00:18:06.160 using Emacs after, afterwards. 00:18:08.000 --> 00:18:08.360 I mean, even in the job, 00:18:09.580 --> 00:18:10.080 right, in the professional field. 00:18:12.900 --> 00:18:13.080 Who, those who keep using Emacs after the 00:18:14.760 --> 00:18:15.180 course, I think the number is greater, 00:18:16.680 --> 00:18:16.920 but I have not followed up on that. 00:18:22.800 --> 00:18:23.140 I have to, my guess is more than half, 00:18:24.860 --> 00:18:25.360 I would say, half or more than half. 00:18:27.660 --> 00:18:27.880 Oh, Aaron, thank you so much. 00:18:31.220 --> 00:18:31.320 That's very sweet. But I didn't think the 00:18:32.080 --> 00:18:32.300 presentation was great. 00:18:33.700 --> 00:18:33.840 I was thinking about redoing it, 00:18:35.200 --> 00:18:35.700 but this is actually the first take. 00:18:38.360 --> 00:18:38.860 It was late, I had lots of other stuff to do. 00:18:44.440 --> 00:18:44.700 I think what I'm more interested in than 00:18:46.760 --> 00:18:47.260 papers is probably this idea of making 00:18:50.860 --> 00:18:51.020 Emacs-based data science videos because there 00:18:51.840 --> 00:18:52.120 aren't many out there. 00:18:53.100 --> 00:18:53.600 Most of the people who do, 00:18:56.980 --> 00:18:57.240 and computer science, most people who do that 00:18:59.060 --> 00:18:59.240 are not either developers and certainly not 00:19:01.640 --> 00:19:02.080 teachers. So I think that's a good idea. 00:19:03.240 --> 00:19:03.740 I'm gonna pick that up. 00:19:15.040 --> 00:19:15.540 So to do more Remax based data science videos 00:19:19.700 --> 00:19:20.200 Is there anything else? 00:19:22.260 --> 00:19:22.360 More people. There are some people here in 00:19:22.800 --> 00:19:23.300 the room still. 00:19:25.600 --> 00:19:26.100 [Speaker 2]: If you do a PSVL on work. 00:19:30.640 --> 00:19:31.140 What? Or wiki. What's my YouTube channel? 00:19:35.720 --> 00:19:36.220 [Speaker 1]: Oh, yeah, I'm going to give you the, 00:19:38.160 --> 00:19:38.520 I've got a bunch of different YouTube 00:19:40.580 --> 00:19:40.720 channels. I'm going to put them in the 00:19:42.740 --> 00:19:43.240 comments to my talk. Hold on, 00:19:46.000 --> 00:19:46.500 the 1 where I have the latest Emacs videos, 00:19:48.480 --> 00:19:48.740 you find my name, there's nobody in the world 00:19:50.560 --> 00:19:51.060 with my name. So if you look for Gerten Krag 00:19:55.240 --> 00:19:55.740 on YouTube, then you will find it. 00:20:00.060 --> 00:20:00.320 [Speaker 2]: But I got a bunch of them. 00:20:01.440 --> 00:20:01.940 Hold on, I'm going to give you the... 00:20:19.540 --> 00:20:20.040 [Speaker 1]: My channel. Okay, This 1 has only got a few 00:20:23.800 --> 00:20:24.300 videos. But so there's 1 with a lot more. 00:20:32.220 --> 00:20:32.720 Few recent videos. And I'm going to post 00:20:41.120 --> 00:20:41.320 more. Other ones in the comments of this 00:20:43.840 --> 00:20:44.340 video. Okay, what else? 00:20:50.640 --> 00:20:51.140 I'm trying to find my way back to the button. 00:20:58.980 --> 00:20:59.200 Okay, cool. Oh, yes, thank you. 00:21:01.220 --> 00:21:01.500 I will. That's very good. 00:21:02.780 --> 00:21:03.120 Thank you so much. Of course, 00:21:05.440 --> 00:21:05.940 I use Vork. I hadn't even thought of it. 00:21:14.640 --> 00:21:15.140 Very good. It's interesting, 00:21:17.520 --> 00:21:18.020 that's something that comes to my mind. 00:21:19.200 --> 00:21:19.700 When I was a young student, 00:21:23.800 --> 00:21:24.020 right, people who used Emacs and the web 00:21:25.420 --> 00:21:25.920 wasn't particularly large. 00:21:29.180 --> 00:21:29.440 So the volunteers would automatically make 00:21:30.920 --> 00:21:31.420 videos but not for commercial purposes. 00:21:34.400 --> 00:21:34.740 Now you have an army of people who make 00:21:37.200 --> 00:21:37.700 commercial videos and the videos are usually 00:21:40.560 --> 00:21:41.040 good for the first 10% of every content, 00:21:42.340 --> 00:21:42.540 but as soon as it gets a little more 00:21:44.620 --> 00:21:44.760 difficult, they either don't know what to do 00:21:48.420 --> 00:21:48.600 anymore or they don't do it because it's not 00:21:50.820 --> 00:21:50.980 commercially viable. The number of people who 00:21:53.520 --> 00:21:53.680 move on is gets smaller and smaller and 00:21:55.240 --> 00:21:55.740 smaller. So there's no commerce anymore. 00:21:57.340 --> 00:21:57.840 But when I was a student, 00:22:00.480 --> 00:22:00.980 pretty much all the documentation everywhere 00:22:01.880 --> 00:22:02.380 was created by volunteers, 00:22:04.640 --> 00:22:04.840 just like this conference or like anything in 00:22:09.320 --> 00:22:09.480 org mode. And that doesn't seem to be much of 00:22:12.260 --> 00:22:12.760 a trend anymore, but maybe we can resurrect 00:22:22.360 --> 00:22:22.500 it. So, yes, I'm definitely going to 00:22:25.640 --> 00:22:25.840 contribute to that. Multiple people are 00:22:30.540 --> 00:22:31.040 typing here. Oh, sorry. 00:22:35.680 --> 00:22:36.180 Yes. Thank you so much. 00:22:40.760 --> 00:22:40.920 I'm gonna put that, I'm gonna rectify that in 00:22:44.920 --> 00:22:45.260 the comment. Having said that, 00:22:49.320 --> 00:22:49.820 I am not 100% sure that I didn't lie here. 00:22:52.480 --> 00:22:52.760 May just be because I didn't have much time 00:22:53.860 --> 00:22:54.340 to put the presentation together. 00:22:56.480 --> 00:22:56.820 And it's perfectly possible that that's 00:22:59.280 --> 00:22:59.780 actually Google slides and not all reveal. 00:23:02.120 --> 00:23:02.320 In the classroom when I present and just do 00:23:03.600 --> 00:23:04.100 lectures, I always do reveal, 00:23:07.400 --> 00:23:07.900 but most of the time I do a tree slide. 00:23:10.520 --> 00:23:10.840 That's the quickest way to do it for me. 00:23:14.640 --> 00:23:15.060 So, so presentation. Hold on, 00:23:16.080 --> 00:23:16.580 Let me just copy this 1. 00:23:20.320 --> 00:23:20.820 Make sure that this doesn't get lost. 00:23:22.700 --> 00:23:23.200 Thank you so much for that. 00:23:25.600 --> 00:23:26.100 And presentations in class. 00:23:29.820 --> 00:23:30.320 I use sometimes org-present, 00:23:32.360 --> 00:23:32.860 but there are issues with the font sometimes. 00:23:36.560 --> 00:23:36.960 I use Treeslide most of the time and Org 00:23:44.220 --> 00:23:44.720 [Speaker 2]: tool. 00:23:46.560 --> 00:23:46.780 [Speaker 1]: Reveal. But this 1 is my top Of course, 00:23:48.640 --> 00:23:49.140 this is not org, so forget about that. 00:24:07.720 --> 00:24:08.220 Okay. Yeah, so you can send me your, 00:24:11.680 --> 00:24:12.160 you've got my email, I think, 00:24:13.780 --> 00:24:14.060 on the end, if you're interested in following 00:24:15.860 --> 00:24:16.360 up or letting me know about your stuff. 00:24:17.720 --> 00:24:18.220 It might be interesting to, 00:24:19.840 --> 00:24:20.060 I don't know, might be interesting to put 00:24:21.540 --> 00:24:22.040 together a conference or a little seminar 00:24:22.500 --> 00:24:23.000 just for educators. 00:24:38.770 --> 00:24:39.025 DF is still typing, I'm waiting. 00:24:39.280 --> 00:24:39.780 I'm waiting. 00:24:45.920 --> 00:24:46.420 [Speaker 2]: Actually, our mod maintainer, 00:24:51.860 --> 00:24:52.280 Bastian, was talking about the possibility to 00:24:53.620 --> 00:24:54.120 have just an Org Mod conference. 00:24:59.020 --> 00:24:59.200 But the question is, is it worth making a 00:25:02.440 --> 00:25:02.940 [Speaker 1]: A whole separate 1 what? 00:25:04.740 --> 00:25:05.020 [Speaker 2]: whole separate 1? A whole separate org 00:25:09.100 --> 00:25:09.600 [Speaker 1]: Oh, I see. Yeah, probably would be. 00:25:10.840 --> 00:25:11.340 Actually. 00:25:13.660 --> 00:25:13.940 [Speaker 2]: dedicated conference. It's just like you see 00:25:15.480 --> 00:25:15.980 how EmacsConf is well done. 00:25:19.080 --> 00:25:19.440 So it's like creating anything that as good 00:25:25.040 --> 00:25:25.540 [Speaker 1]: Yes. No, I think that's a good idea. 00:25:26.120 --> 00:25:26.620 Yeah, I mean. 00:25:30.100 --> 00:25:30.480 [Speaker 2]: as tricky. I mean, Okay, 00:25:32.560 --> 00:25:32.920 it's anywhere, like half of Emacs is anywhere 00:25:36.380 --> 00:25:36.880 remote. So it's almost the same. 00:25:39.960 --> 00:25:40.200 [Speaker 1]: Yeah. Well, I suppose at this point, 00:25:41.260 --> 00:25:41.580 I don't know if that's what you mean, 00:25:44.820 --> 00:25:45.040 Org Mode is probably what attracts people to 00:25:46.620 --> 00:25:47.060 Emacs in the first place. 00:25:50.540 --> 00:25:51.040 Like, I suppose Org Roam is the, 00:25:54.140 --> 00:25:54.600 maybe the biggest 1 for people even outside 00:25:57.540 --> 00:25:58.040 of computer science. I use Org.ROM 00:26:07.380 --> 00:26:07.560 for everything. I think the maintainer or 00:26:08.660 --> 00:26:09.140 maybe the creator of Org.MODE 00:26:11.460 --> 00:26:11.740 has claimed and said for many years that Org 00:26:13.940 --> 00:26:14.220 Mode itself doesn't actually necessarily need 00:26:16.440 --> 00:26:16.940 Emacs. You can have it as a completely 00:26:18.160 --> 00:26:18.660 separate application as well. 00:26:20.600 --> 00:26:21.020 But for a number of reasons, 00:26:23.300 --> 00:26:23.440 I don't like that. I really like the idea to 00:26:30.420 --> 00:26:30.660 [Speaker 2]: why- The current strategy is that It has to 00:26:33.420 --> 00:26:33.580 be Emacs because the configurability is 1 of 00:26:34.700 --> 00:26:35.140 the strong points anyway. 00:26:35.400 --> 00:26:35.800 [Speaker 1]: have it inside Emacs. The reason That's true. 00:26:37.120 --> 00:26:37.620 [Speaker 2]: You cannot make a separate application. 00:26:39.640 --> 00:26:39.800 [Speaker 1]: No, that's true. I was going to say that. 00:26:40.960 --> 00:26:41.460 The thing is you use the flexibility. 00:26:42.720 --> 00:26:43.220 Plus, you also use the, 00:26:45.800 --> 00:26:46.080 I don't know if that's the right word, 00:26:48.380 --> 00:26:48.760 but you use there's something about the free 00:26:52.420 --> 00:26:52.600 ideology of Emacs that is what attracted me 00:26:55.760 --> 00:26:56.260 to it in the first place when I was younger 00:26:59.620 --> 00:27:00.120 and that I find even more important now. 00:27:02.980 --> 00:27:03.480 So what they say the community aspect, 00:27:08.600 --> 00:27:08.800 the reason, the main reason why Python is so 00:27:12.620 --> 00:27:13.120 big today, really. So yeah. 00:27:17.440 --> 00:27:17.860 [Speaker 2]: But in terms of going out of Emacs, 00:27:20.800 --> 00:27:21.300 it's org syntax that is supposed to be like 00:27:22.760 --> 00:27:23.260 breaking out of Emacs. 00:27:28.340 --> 00:27:28.540 Yeah. So like there's a plan to lay out the 00:27:30.720 --> 00:27:30.920 actual standard document so that you can 00:27:32.040 --> 00:27:32.540 register the format officially. 00:27:34.440 --> 00:27:34.760 [Speaker 1]: Yeah, I think I've heard that too. 00:27:36.060 --> 00:27:36.560 I've not followed up on it much. 00:27:38.820 --> 00:27:39.320 I don't know what the, 00:27:40.760 --> 00:27:41.260 I mean, that probably would, 00:27:43.520 --> 00:27:43.780 it would very likely, if you do that, 00:27:45.060 --> 00:27:45.380 it would at least for a short time, 00:27:47.160 --> 00:27:47.660 strengthen org mode and weaken emacs. 00:27:50.380 --> 00:27:50.880 I don't know what other examples, 00:27:54.180 --> 00:27:54.680 if there are other examples of applications 00:27:57.560 --> 00:27:57.840 pulled out of IDEs like that. 00:27:58.940 --> 00:27:59.440 I'm not aware of any others. 00:28:02.420 --> 00:28:02.660 [Speaker 2]: Actually, people are trying to make 00:28:04.700 --> 00:28:04.920 three-seater drama, people are trying to make 00:28:05.740 --> 00:28:06.120 like some external parsers, 00:28:09.920 --> 00:28:10.320 a lot of them. And a lot of stuff is done on 00:28:11.820 --> 00:28:12.320 mobile part, like Android, 00:28:13.820 --> 00:28:14.320 iOS, especially recently. 00:28:18.480 --> 00:28:18.980 So things that are Emacs independent are 00:28:22.940 --> 00:28:23.040 [Speaker 1]: Okay, yeah. I have no doubt that there is a 00:28:26.120 --> 00:28:26.620 [Speaker 2]: demanded. Especially in the environment, 00:28:27.540 --> 00:28:28.040 like every time. 00:28:30.480 --> 00:28:30.680 [Speaker 1]: demand. Yeah. I mean, I didn't get into that 00:28:34.640 --> 00:28:35.020 very much. I have some of my students have 0 00:28:36.400 --> 00:28:36.900 affinity with computers. 00:28:39.720 --> 00:28:39.900 They really don't know their way around their 00:28:43.820 --> 00:28:44.320 computers at all. And so for them, 00:28:50.980 --> 00:28:51.440 It is quite important to learn how to find 00:28:56.380 --> 00:28:56.520 your way around Emacs because it's like a 00:28:57.320 --> 00:28:57.820 little operating system, 00:29:00.060 --> 00:29:00.300 but it's not. It's an operating system 00:29:03.460 --> 00:29:03.960 without much of the obscurity. 00:29:07.760 --> 00:29:07.960 And the alternative to that would be to 00:29:10.040 --> 00:29:10.520 simply let them work only on the command 00:29:11.980 --> 00:29:12.480 line, which is another possibility. 00:29:16.040 --> 00:29:16.160 But, you know, there of course you are 00:29:20.200 --> 00:29:20.520 limited with regard to if you want to swap 00:29:23.000 --> 00:29:23.500 languages. So for example, 00:29:25.900 --> 00:29:26.000 quite often I find myself in the situation I 00:29:28.660 --> 00:29:28.780 teach data science in R and Python and in 00:29:31.360 --> 00:29:31.520 Emacs org mode I can demonstrate both of 00:29:34.600 --> 00:29:35.100 these side by side in the same file. 00:29:38.200 --> 00:29:38.700 And that's a great advantage. 00:29:42.040 --> 00:29:42.540 Not to overburden the students when they are 00:29:44.900 --> 00:29:45.100 at the beginning with things that you don't 00:29:47.120 --> 00:29:47.620 want them to necessarily learn about. 00:29:50.560 --> 00:29:51.000 And plus the thing what I like as a graduate 00:29:54.240 --> 00:29:54.400 student when I stepped onto Emacs was that it 00:29:59.960 --> 00:30:00.140 was infinite possibilities to lose myself in 00:30:02.640 --> 00:30:03.060 Emacs and you know go on and learn more stuff 00:30:06.180 --> 00:30:06.340 about it. But it's such a long time ago that 00:30:09.860 --> 00:30:10.360 I barely dare to mention it anymore. 00:30:12.500 --> 00:30:12.880 [Speaker 2]: For command line, actually, 00:30:16.820 --> 00:30:17.080 it's since the Jupyter notebooks and that 00:30:18.880 --> 00:30:19.380 Google thing they are running. 00:30:23.640 --> 00:30:23.820 It's getting so popular that it's clear that 00:30:26.600 --> 00:30:26.760 command line is just losing in popularity in 00:30:31.420 --> 00:30:31.920 [Speaker 1]: well, yes and no. I mean, 00:30:32.860 --> 00:30:33.360 [Speaker 2]: this. Yeah, of course, 00:30:38.160 --> 00:30:38.400 Not the usage. People are still using it, 00:30:38.400 --> 00:30:38.900 obviously. 00:30:40.520 --> 00:30:41.020 [Speaker 1]: I mean, in Google Colab, 00:30:43.440 --> 00:30:43.620 only the paid version allows you to go to the 00:30:44.960 --> 00:30:45.460 terminal and use the command line. 00:30:48.140 --> 00:30:48.580 But of course, the traction, 00:30:49.640 --> 00:30:50.140 and I think that's kind of interesting, 00:30:54.560 --> 00:30:54.680 1 of the reasons why IPython or any of the 00:30:56.780 --> 00:30:56.960 Jupyter notebooks are so cool is because you 00:30:59.440 --> 00:30:59.940 can use a lot of shell commands from the 00:31:04.620 --> 00:31:05.100 IPython shell. There's a whole bunch of magic 00:31:06.460 --> 00:31:06.960 commands which are quite powerful. 00:31:09.620 --> 00:31:10.120 The 1 that comes to mind is a time, 00:31:11.820 --> 00:31:12.320 the time command, for example, 00:31:13.580 --> 00:31:14.080 you know, it gives you a really nice, 00:31:16.400 --> 00:31:16.800 performance, quick performance check. 00:31:17.660 --> 00:31:18.120 There's a bunch of different, 00:31:20.500 --> 00:31:20.900 I think probably close to a hundred magic 00:31:22.340 --> 00:31:22.840 commands that you can use in Jupyter. 00:31:25.600 --> 00:31:25.840 But I don't know JupyterLab too well, 00:31:28.840 --> 00:31:29.220 but I noticed that the companies that do 00:31:30.920 --> 00:31:31.080 online training, And they are usually the 00:31:34.600 --> 00:31:34.920 ones that are closest to what beginners want, 00:31:35.600 --> 00:31:36.100 especially in business. 00:31:40.780 --> 00:31:40.960 And what those companies do is they take 00:31:43.040 --> 00:31:43.220 JupiterLab and turn it into a presentation of 00:31:44.300 --> 00:31:44.800 their own. Another 1 is Notable, 00:31:47.380 --> 00:31:47.880 notable.io. That's another 1. 00:31:50.280 --> 00:31:50.500 They took JupyterLab and turned it into 00:31:52.080 --> 00:31:52.200 something commercial. It's boosted up a 00:31:58.680 --> 00:31:58.860 little bit. And so the shell inside the 00:32:01.680 --> 00:32:01.960 JupyterLab has some of the most more 00:32:03.120 --> 00:32:03.620 important shell properties. 00:32:05.800 --> 00:32:06.000 And so people still use the command line 00:32:07.200 --> 00:32:07.600 without knowing that they use the command 00:32:12.600 --> 00:32:13.100 line. But I also like doing, 00:32:14.820 --> 00:32:15.320 how do I use org-roam? 00:32:21.900 --> 00:32:22.020 Well, I use it, I do not have not used it 00:32:22.720 --> 00:32:23.000 with the students yet, 00:32:24.800 --> 00:32:25.020 only the best students have sort of seen me 00:32:29.440 --> 00:32:29.760 use it and copied it. But I use it probably 00:32:31.680 --> 00:32:32.000 in a very naive, trivial way. 00:32:33.080 --> 00:32:33.580 I can't say that I am, 00:32:36.460 --> 00:32:36.960 that I have a very sophisticated use. 00:32:39.480 --> 00:32:39.640 I basically, I like the fact that, 00:32:42.940 --> 00:32:43.100 I mean, it's built on the original concept of 00:32:44.280 --> 00:32:44.540 the, with the German word, 00:32:47.900 --> 00:32:48.280 Zettelkasten, right? Which is that you do not 00:32:50.780 --> 00:32:50.940 have to think about a taxonomy because as you 00:32:53.620 --> 00:32:53.800 move along, your taxonomy changes all the 00:32:55.200 --> 00:32:55.580 time. You know, what you think is important 00:32:56.820 --> 00:32:57.320 at the beginning, your root node, 00:32:58.480 --> 00:32:58.940 as you go along, you realize, 00:33:00.220 --> 00:33:00.600 oh, that's not the root node at all. 00:33:02.560 --> 00:33:02.720 There's a higher level and a higher level and 00:33:04.540 --> 00:33:04.780 some of the lower levels aren't at the lower 00:33:05.860 --> 00:33:06.280 level, they're actually at the higher level. 00:33:09.960 --> 00:33:10.460 So you're beginning to create hierarchies 00:33:13.940 --> 00:33:14.280 that are out of date as soon as you create 00:33:16.260 --> 00:33:16.360 the hierarchy. So what is the idea of the 00:33:18.340 --> 00:33:18.480 tittle custom is that anything that comes to 00:33:20.600 --> 00:33:21.100 your mind you can throw in the custom the box 00:33:26.240 --> 00:33:26.540 it literally means Box of notes and That's 00:33:27.560 --> 00:33:27.740 what I appreciate about it. 00:33:32.780 --> 00:33:32.920 So I create a I create a note pretty much for 00:33:35.280 --> 00:33:35.780 anything I do, but I've only used it for 00:33:37.660 --> 00:33:38.160 about a year and a half or so, 00:33:39.240 --> 00:33:39.740 or grown, maybe a year. 00:33:43.380 --> 00:33:43.700 So I can see that I'm coming up against the 00:33:46.480 --> 00:33:46.980 Zettelkasten or note box problems, 00:33:50.660 --> 00:33:50.860 which is that I've got so many notes now that 00:33:52.460 --> 00:33:52.960 unless I have clever aliases, 00:33:56.580 --> 00:33:56.680 there is a chance that I might forget that I 00:33:59.540 --> 00:34:00.040 [Speaker 2]: That's why you need meta-notes. 00:34:01.100 --> 00:34:01.600 [Speaker 1]: have a note. So I need a- Yes, 00:34:04.420 --> 00:34:04.920 [Speaker 2]: In other words, a summarization is important, 00:34:06.300 --> 00:34:06.800 no matter what system you use. 00:34:09.600 --> 00:34:09.719 [Speaker 1]: yes. But what I'm trying to say is that's a 00:34:10.760 --> 00:34:11.260 different approach than hierarchies, 00:34:13.280 --> 00:34:13.580 right? It's the same, it's the same, 00:34:15.460 --> 00:34:15.960 it's the same principle as a relational 00:34:18.219 --> 00:34:18.719 database versus a hierarchical database. 00:34:23.179 --> 00:34:23.360 Same thing. So, yeah, I've not used that. 00:34:25.199 --> 00:34:25.400 I've not really used, actually I have cut 00:34:26.520 --> 00:34:27.020 meta notes, of course I do. 00:34:28.500 --> 00:34:28.940 So notes that point to other notes. 00:34:31.920 --> 00:34:32.320 Yes, of course. I use those. 00:34:32.780 --> 00:34:33.280 I have forgotten that. 00:34:38.300 --> 00:34:38.800 I have not taught that part to the students 00:34:42.340 --> 00:34:42.840 because I do project work with the students, 00:34:46.080 --> 00:34:46.360 but there's only so much time. 00:34:47.719 --> 00:34:48.219 I'm already, I mean, already, 00:34:50.800 --> 00:34:50.980 I don't think there's any class that where I 00:34:55.320 --> 00:34:55.820 am able to use more than 30% of my material. 00:34:57.400 --> 00:34:57.620 And the reason is that when the students come 00:34:59.120 --> 00:34:59.220 to class, which is I pointed out in the 00:35:00.600 --> 00:35:01.100 video, they know so little. 00:35:03.280 --> 00:35:03.720 And most of the students, 00:35:04.680 --> 00:35:04.960 at least in liberal arts, 00:35:09.780 --> 00:35:10.280 spend just too little time outside of class, 00:35:11.440 --> 00:35:11.600 getting there, you know, 00:35:12.660 --> 00:35:13.040 drilling down into the, 00:35:14.140 --> 00:35:14.640 into the, into the infrastructure, 00:35:16.700 --> 00:35:17.060 into the work. Only, only the best students 00:35:18.820 --> 00:35:19.320 do that. The ones that really catch fire. 00:35:21.960 --> 00:35:22.280 [Speaker 2]: Don't you have something like a course 00:35:23.260 --> 00:35:23.760 project at the end? 00:35:25.460 --> 00:35:25.760 [Speaker 1]: Yes, I have course, not at the end. 00:35:27.340 --> 00:35:27.720 I use Scrum. Maybe I shouldn't, 00:35:29.140 --> 00:35:29.640 but I've used Scrum for many years. 00:35:32.440 --> 00:35:32.600 So I have course projects that start at the 00:35:35.080 --> 00:35:35.320 beginning and they do sprint reviews every 3 00:35:40.380 --> 00:35:40.640 or 4 weeks. So term end projects I find 00:35:42.880 --> 00:35:43.100 completely useless because the students do 00:35:44.760 --> 00:35:45.260 the work at the very end of the term. 00:35:49.600 --> 00:35:49.740 [Speaker 2]: By term end I mean they don't start at the 00:35:51.380 --> 00:35:51.880 end, they just report at the end. 00:35:53.800 --> 00:35:54.300 [Speaker 1]: I use the IMRAD, I use the IMRAD method. 00:35:57.720 --> 00:35:58.220 So I use IMRAD, basically IMRAD plus, 00:35:59.900 --> 00:36:00.300 plus Scrum, right? So, 00:36:01.720 --> 00:36:02.220 So the first sprint review is introductory, 00:36:02.980 --> 00:36:03.480 the research proposal, 00:36:04.540 --> 00:36:05.040 the second 1 is about methodology, 00:36:05.880 --> 00:36:06.360 the third 1 about results, 00:36:07.540 --> 00:36:08.040 and the last 1 is their final presentation. 00:36:10.600 --> 00:36:11.100 And so that's the way I manage the projects, 00:36:15.760 --> 00:36:16.020 but that's about as much as I can do with 00:36:17.380 --> 00:36:17.680 them. It's a good idea. 00:36:19.280 --> 00:36:19.780 I hadn't even thought about using Org-ROM 00:36:22.640 --> 00:36:22.760 with them, but to teach them that might be a 00:36:23.680 --> 00:36:24.180 good idea, actually. 00:36:26.720 --> 00:36:27.220 [Speaker 2]: Well, for Org-ROM, actually, 00:36:32.060 --> 00:36:32.340 what I found useful during my graduate is for 00:36:34.240 --> 00:36:34.740 literature review. Yes. 00:36:37.080 --> 00:36:37.340 The other part of our program that is not 00:36:39.520 --> 00:36:40.020 about your like, noting down your thoughts, 00:36:42.340 --> 00:36:42.840 is about writing about literature notes. 00:36:44.860 --> 00:36:45.180 [Speaker 1]: Yeah, that's a good idea, 00:36:45.780 --> 00:36:46.060 actually. And of course, 00:36:47.660 --> 00:36:47.960 I mean, there's more stuff that they should 00:36:49.700 --> 00:36:50.140 learn, you know, like another 1, 00:36:51.280 --> 00:36:51.780 since you mentioned literature, 00:36:54.140 --> 00:36:54.640 you know, latex and Bibtech is another 00:36:57.340 --> 00:36:57.840 obvious extension of that. 00:37:01.020 --> 00:37:01.120 But that is actually a good idea because the 00:37:02.720 --> 00:37:03.080 literature is what they have the hardest time 00:37:06.560 --> 00:37:06.980 [Speaker 2]: Yeah, like when you need to read like 50 00:37:06.980 --> 00:37:07.480 papers. 00:37:12.260 --> 00:37:12.480 [Speaker 1]: with. Last term, since you mentioned that, 00:37:16.020 --> 00:37:16.220 I had a really nice experience because 1 of 00:37:17.800 --> 00:37:18.300 our librarians, our digital librarian, 00:37:19.480 --> 00:37:19.920 came along and talked to the students, 00:37:21.300 --> 00:37:21.580 and he taught me about a tool called 00:37:23.040 --> 00:37:23.540 litmap.com, which is basically, 00:37:24.920 --> 00:37:25.420 I don't know how it's implemented, 00:37:26.680 --> 00:37:27.180 but it's basically a graph, 00:37:31.380 --> 00:37:31.620 a graph representation of papers organized by 00:37:35.080 --> 00:37:35.580 citation. It's very, very cool. 00:37:38.160 --> 00:37:38.560 And the students who used to only find, 00:37:40.520 --> 00:37:41.020 I don't know, 1 paper and otherwise, 00:37:44.440 --> 00:37:44.940 of course, 15 YouTube videos and 100 blogs, 00:37:48.860 --> 00:37:49.360 suddenly started finding and reading 00:37:51.960 --> 00:37:52.120 scientific papers. It was only because of 00:37:54.400 --> 00:37:54.900 this presentation. So you should take the, 00:37:57.060 --> 00:37:57.560 I think, I hope that is the right, 00:37:59.060 --> 00:37:59.560 that's the right mode, 00:38:01.940 --> 00:38:02.380 litmaps. Okay, it's not litmap, 00:38:05.500 --> 00:38:05.640 it's called Litmaps. I'm gonna give you an 00:38:08.860 --> 00:38:09.000 example. I don't know if I can share this, 00:38:09.840 --> 00:38:10.240 if you can look at that. 00:38:13.140 --> 00:38:13.640 But basically you create a, 00:38:16.080 --> 00:38:16.580 1 can use 1 of your papers as a seed, 00:38:18.340 --> 00:38:18.840 and then it will create a graph, 00:38:21.260 --> 00:38:21.760 graph representation of it for you. 00:38:24.720 --> 00:38:25.220 And this is a powerful tool in itself. 00:38:27.100 --> 00:38:27.600 But what I'm saying is that the students 00:38:30.700 --> 00:38:30.860 suddenly, their use of literature and that 00:38:32.120 --> 00:38:32.620 citation goes to the roof. 00:38:35.800 --> 00:38:36.140 And I've been waiting for that for probably 00:38:37.760 --> 00:38:38.260 15 years since I've started teaching. 00:38:42.900 --> 00:38:43.400 So it's crazy. That's really cool. 00:38:47.440 --> 00:38:47.720 [Speaker 2]: So here is the same tool, 00:38:48.900 --> 00:38:49.400 it's called connected papers. 00:38:53.040 --> 00:38:53.540 It's based on the open source citation data. 00:38:55.840 --> 00:38:56.340 [Speaker 1]: Yeah, I know that as well, 00:38:56.680 --> 00:38:57.180 I think. 00:39:01.240 --> 00:39:01.480 [Speaker 2]: It's actually very useful when you just start 00:39:03.680 --> 00:39:03.960 learning the topic, it's like you find 1 00:39:05.320 --> 00:39:05.800 paper, then you look into the connections, 00:39:07.900 --> 00:39:08.260 you can quickly narrow down to the most 00:39:09.760 --> 00:39:10.260 cited, the core papers on the topic. 00:39:12.340 --> 00:39:12.520 [Speaker 1]: Of course, and that is exactly their 00:39:14.640 --> 00:39:14.820 situation, you know, and they're always at 00:39:16.240 --> 00:39:16.740 the beginning. As you go on, 00:39:18.420 --> 00:39:18.680 you develop different ways, 00:39:19.640 --> 00:39:20.140 but for these complete beginners, 00:39:22.500 --> 00:39:22.680 that's a good idea. Thank you so much for 00:39:30.020 --> 00:39:30.520 [Speaker 0]: anything else? 00:39:31.820 --> 00:39:31.940 [Speaker 1]: that. Okay, guys, I've enjoyed the 00:39:33.460 --> 00:39:33.960 conversation, so you should definitely, 00:39:37.440 --> 00:39:37.940 I'm going to take some of these things away. 00:39:41.840 --> 00:39:42.280 Thank you so much for that. 00:39:45.240 --> 00:39:45.740 Have you done, Yanta, have you done org mode 00:39:47.700 --> 00:39:48.200 documentations yourself on WOC? 00:39:51.820 --> 00:39:52.120 Or do you have a sort of a favorite 1? 00:39:53.160 --> 00:39:53.600 I mean, I often on walk, 00:39:56.480 --> 00:39:56.740 I often use the documentation for code 00:39:59.440 --> 00:39:59.620 blocks. I used to when I started doing that 00:40:02.320 --> 00:40:02.800 [Speaker 2]: Yeah, because it's only on work. 00:40:03.760 --> 00:40:04.260 It's not part of the manual. 00:40:05.140 --> 00:40:05.280 [Speaker 1]: for the first time. Yeah, 00:40:06.940 --> 00:40:07.440 yeah. And so I've used that a lot. 00:40:09.060 --> 00:40:09.560 [Speaker 2]: Have I done? Not really, 00:40:10.960 --> 00:40:11.460 mostly fixing the errors. 00:40:15.360 --> 00:40:15.560 Okay. Yeah, I think that's a really good 00:40:15.560 --> 00:40:16.060 idea. 00:40:19.280 --> 00:40:19.780 [Speaker 1]: All right. Well, thank you very much. 00:40:22.040 --> 00:40:22.360 And it's great to be at this conference. 00:40:23.940 --> 00:40:24.440 I think I'm going to get on. 00:40:28.740 --> 00:40:29.240 [Speaker 2]: Thanks for answering all the questions. 00:40:32.400 --> 00:40:32.560 And for the talk, It was quite interesting to 00:40:35.160 --> 00:40:35.660 see our modules in actual teaching. 00:40:38.240 --> 00:40:38.560 [Speaker 1]: Yes, thank you. And I got to thank Daniel 00:40:40.600 --> 00:40:40.840 German from Canada, the 1 of, 00:40:43.580 --> 00:40:43.660 I had him on 1 of the slides because he, 00:40:45.140 --> 00:40:45.350 he inspired me to do that. 00:40:47.420 --> 00:40:47.540 And, and I wouldn't be at the conference if I 00:40:49.280 --> 00:40:49.480 hadn't contacted him and said oh here's my 00:40:50.860 --> 00:40:51.020 paper and he said oh you should come to the 00:40:52.540 --> 00:40:52.680 conference and so that's why I came to the 00:40:58.200 --> 00:40:58.480 conference.
