+WEBVTT captioned by James Howell, checked by sachac
+
+NOTE Introduction
+
+00:00:00.000 --> 00:00:01.939
+Hello everyone. I'm James Howell.
+
+00:00:01.940 --> 00:00:03.539
+I teach biochemistry and
+
+00:00:03.540 --> 00:00:07.219
+molecular biology at Penn State University.
+
+00:00:07.220 --> 00:00:08.879
+I'm going to talk today
+
+00:00:08.880 --> 00:00:11.479
+about using Emacs to make all of
+
+00:00:11.480 --> 00:00:13.619
+the materials for presenting
+
+00:00:13.620 --> 00:00:15.679
+course meetings in my courses.
+
+00:00:15.680 --> 00:00:18.819
+Everything that you're going to see today is
+
+00:00:18.820 --> 00:00:20.439
+what I've made using
+
+00:00:20.440 --> 00:00:23.519
+the methods that I'm going to describe.
+
+00:00:26.200 --> 00:00:29.719
+The main point is that you can take
+
+00:00:29.720 --> 00:00:32.079
+an Org document and
+
+00:00:32.080 --> 00:00:34.469
+with a single Emacs document,
+
+00:00:34.470 --> 00:00:39.079
+make both a pretty text document
+
+00:00:39.080 --> 00:00:40.379
+that a student can have
+
+00:00:40.380 --> 00:00:42.039
+on the desk and take notes on.
+
+00:00:42.040 --> 00:00:44.439
+And also, I hope,
+
+00:00:44.440 --> 00:00:49.039
+fairly useful and attractive slides
+
+00:00:49.040 --> 00:00:51.339
+like the ones that I'm presenting right now.
+
+00:00:51.340 --> 00:00:52.859
+Both of these
+
+00:00:52.860 --> 00:00:56.659
+from a single source document.
+
+00:00:56.660 --> 00:00:59.259
+Okay. If you'd like
+
+00:00:59.260 --> 00:01:00.919
+to see the handout that goes along with this,
+
+00:01:00.920 --> 00:01:02.799
+you can download it
+
+00:01:02.800 --> 00:01:04.059
+at the [Sourcehut] repository where
+
+00:01:04.060 --> 00:01:05.959
+I've put— everything's here.
+
+00:01:05.960 --> 00:01:07.819
+So if you'd like to go look at it,
+
+00:01:07.820 --> 00:01:09.939
+you can follow with the handout.
+
+00:01:09.940 --> 00:01:11.239
+So I promised to talk about
+
+00:01:11.240 --> 00:01:12.439
+both authoring and presenting.
+
+NOTE Presenting
+
+00:01:12.440 --> 00:01:14.619
+And first I'm going to talk about presenting.
+
+00:01:14.620 --> 00:01:16.599
+I'm not the only one who does this.
+
+00:01:16.600 --> 00:01:19.299
+You might have seen System Crafters [David Wilson]
+
+00:01:19.300 --> 00:01:20.639
+or Prot's [Protesilaos Stavrou's] channel or
+
+00:01:20.640 --> 00:01:23.059
+Mike Zemansky's channel on Youtube.
+
+00:01:23.060 --> 00:01:26.679
+(Prot actually is going to be presenting tomorrow.)
+
+00:01:26.680 --> 00:01:28.419
+Maybe you've seen this
+
+00:01:28.420 --> 00:01:30.179
+chemical engineer at Carnegie Mellon,
+
+00:01:30.180 --> 00:01:32.159
+John Kitchin or Eric Fraga
+
+00:01:32.160 --> 00:01:34.139
+or Olivier Berger all have made
+
+00:01:34.140 --> 00:01:36.519
+blog posts about using Org mode
+
+00:01:36.520 --> 00:01:39.419
+to produce course materials.
+
+00:01:39.420 --> 00:01:41.459
+This pair Ro and Namkoon
+
+00:01:41.460 --> 00:01:43.739
+actually published a peer reviewed paper.
+
+00:01:43.740 --> 00:01:45.739
+There's prior art here
+
+00:01:45.740 --> 00:01:47.819
+that I'd like to acknowledge.
+
+NOTE Hardware
+
+00:01:47.820 --> 00:01:50.839
+Let me talk about my practices:
+
+00:01:50.840 --> 00:01:51.518
+First, the hardware.
+
+00:01:51.520 --> 00:01:55.339
+This is the hardware that I'm using to
+
+00:01:55.340 --> 00:01:59.738
+record this recording at the very moment,
+
+00:01:59.740 --> 00:02:01.259
+but also I carry these
+
+00:02:01.260 --> 00:02:05.059
+into every course meeting.
+
+00:02:05.060 --> 00:02:07.119
+I've done this for quite a while,
+
+00:02:07.120 --> 00:02:09.618
+this entire semester,
+
+00:02:09.620 --> 00:02:11.438
+and a few previous semesters
+
+00:02:11.440 --> 00:02:14.239
+where everything fits in a backpack.
+
+00:02:14.240 --> 00:02:18.459
+I do every meeting with this tablet—
+
+00:02:18.460 --> 00:02:20.839
+it's a Microsoft Surface that I put
+
+00:02:20.840 --> 00:02:26.599
+a Linux distribution on—and this laptop.
+
+00:02:26.600 --> 00:02:29.599
+I've got a bag full of
+
+00:02:29.600 --> 00:02:34.078
+dongles and connectors and so forth.
+
+00:02:34.080 --> 00:02:35.339
+It all fits in a backpack.
+
+00:02:35.340 --> 00:02:36.259
+This is very mobile.
+
+00:02:36.260 --> 00:02:38.179
+I can set it up and tear it down
+
+00:02:38.180 --> 00:02:39.699
+before and after every class
+
+00:02:39.700 --> 00:02:41.219
+with just a couple minutes.
+
+00:02:41.220 --> 00:02:42.739
+There's the laptop and the
+
+00:02:42.740 --> 00:02:45.018
+tablet with a stylus.
+
+00:02:45.020 --> 00:02:46.579
+Where's my stylus?
+
+00:02:46.580 --> 00:02:51.498
+So that I can draw...
+
+00:02:51.500 --> 00:02:52.519
+... which is very useful.
+
+00:02:52.520 --> 00:02:55.858
+Obviously, I need a camera.
+
+00:02:55.860 --> 00:02:57.459
+Today, I'm using a desk mic,
+
+00:02:57.460 --> 00:02:59.099
+but when I'm remote,
+
+00:02:59.100 --> 00:03:01.738
+I use a lapel mic.
+
+00:03:01.740 --> 00:03:02.899
+and a video converter,
+
+00:03:02.900 --> 00:03:04.379
+and I'll show you why that's important.
+
+00:03:04.380 --> 00:03:09.018
+And then all of the ancillary equipment.
+
+00:03:09.020 --> 00:03:11.139
+One thing that's nice about using
+
+00:03:11.140 --> 00:03:14.019
+a completely free software stack is
+
+00:03:14.020 --> 00:03:15.219
+that it tends to run
+
+00:03:15.220 --> 00:03:18.318
+on underpowered hardware,
+
+00:03:18.320 --> 00:03:20.539
+and none of the software cost anything.
+
+00:03:20.540 --> 00:03:23.219
+I could have spent much less than this
+
+00:03:23.220 --> 00:03:25.459
+on a used computer and
+
+00:03:25.460 --> 00:03:28.199
+a used tablet. And everything else,
+
+00:03:28.200 --> 00:03:30.299
+these are high estimates.
+
+00:03:30.300 --> 00:03:31.679
+I spent way less than
+
+00:03:31.680 --> 00:03:34.019
+$1,000 for all of this equipment.
+
+00:03:34.020 --> 00:03:35.619
+And it's my equipment,
+
+00:03:35.620 --> 00:03:37.259
+so I have hardware
+
+00:03:37.260 --> 00:03:38.959
+and software control over it,
+
+00:03:38.960 --> 00:03:41.099
+Which is nice.
+
+00:03:41.100 --> 00:03:43.239
+If you have an attitude of upcycling and building,
+
+00:03:43.240 --> 00:03:45.189
+and [if] this is a hobby anyway,
+
+00:03:45.190 --> 00:03:47.129
+this is an easy way—
+
+00:03:47.130 --> 00:03:48.649
+what I'm saying is—
+
+00:03:48.650 --> 00:03:51.369
+the entry into using these things,
+
+00:03:51.370 --> 00:03:58.018
+there's certainly a very low cost barrier.
+
+00:03:58.020 --> 00:04:01.429
+Because the hardware is so weak,
+
+00:04:01.430 --> 00:04:05.249
+I have the tablet for doing tablet stuff,
+
+00:04:05.250 --> 00:04:06.629
+and then I use the laptop to
+
+00:04:06.630 --> 00:04:08.909
+do all of the streaming and recording.
+
+00:04:08.910 --> 00:04:11.609
+I take the video output
+
+00:04:11.610 --> 00:04:13.829
+of the tablet and convert it to
+
+00:04:13.830 --> 00:04:19.898
+USB input into the laptop.
+
+00:04:19.900 --> 00:04:21.929
+Just to give you a diagram here,
+
+00:04:21.930 --> 00:04:23.709
+there's a laptop and there's a tablet.
+
+00:04:23.710 --> 00:04:25.929
+The tablet has a stylus.
+
+00:04:25.930 --> 00:04:29.449
+They both run GNU/Linux distributions.
+
+00:04:29.450 --> 00:04:30.949
+You've got a webcam that
+
+00:04:30.950 --> 00:04:32.129
+goes into the laptop.
+
+00:04:32.130 --> 00:04:33.618
+You've got video output
+
+00:04:33.620 --> 00:04:37.889
+from the tablet that goes into the laptop.
+
+00:04:37.890 --> 00:04:39.349
+There's a microphone that
+
+00:04:39.350 --> 00:04:40.469
+goes into the laptop,
+
+00:04:40.470 --> 00:04:43.209
+and then audio and video come out of
+
+00:04:43.210 --> 00:04:44.409
+the laptop and go into
+
+00:04:44.410 --> 00:04:46.609
+some AV system or another.
+
+NOTE Example setup
+
+00:04:46.610 --> 00:04:49.069
+Okay. This was Wednesday,
+
+00:04:49.070 --> 00:04:51.069
+teaching microbiology.
+
+00:04:51.070 --> 00:04:53.229
+There's the tablet, there's the laptop.
+
+00:04:53.230 --> 00:04:55.369
+There's the external screen
+
+00:04:55.370 --> 00:04:57.209
+in the podium here you can
+
+00:04:57.210 --> 00:04:59.549
+plug into the AV system.
+
+00:05:00.470 --> 00:05:04.209
+There it is. From where I stand,
+
+00:05:04.210 --> 00:05:06.009
+this is what the screen looks like.
+
+00:05:06.010 --> 00:05:08.224
+This is what students are seeing,
+
+00:05:08.225 --> 00:05:09.459
+on the live stream
+
+00:05:09.460 --> 00:05:10.779
+and later on the recording.
+
+00:05:10.780 --> 00:05:11.719
+And students in the room
+
+00:05:11.720 --> 00:05:12.639
+can see this as well.
+
+00:05:12.640 --> 00:05:15.099
+So you notice this is kind of meta,
+
+00:05:15.100 --> 00:05:17.139
+but the camera and
+
+00:05:17.140 --> 00:05:18.759
+the contents of the screen are
+
+00:05:18.760 --> 00:05:20.499
+there when I wander around,
+
+00:05:20.500 --> 00:05:22.219
+and when I stand in front of the screen,
+
+00:05:22.220 --> 00:05:23.939
+the students who aren't in the room can
+
+00:05:23.940 --> 00:05:27.398
+still see what I'm pointing to on the screen.
+
+00:05:27.400 --> 00:05:30.518
+Nobody gets left out.
+
+NOTE Presentation software: flexibility in function
+
+00:05:30.520 --> 00:05:31.479
+Let's talk about
+
+00:05:31.480 --> 00:05:33.579
+the software that I use.
+
+00:05:33.900 --> 00:05:35.979
+There's a lot of different things that
+
+00:05:35.980 --> 00:05:37.639
+I want to be able to show.
+
+00:05:37.640 --> 00:05:39.299
+And so I need a few different
+
+00:05:39.300 --> 00:05:42.399
+software packages— besides Emacs.
+
+00:05:42.400 --> 00:05:45.079
+For drawing on the tablet, I use
+
+00:05:45.080 --> 00:05:48.359
+(I don't know quite how this is pronounced:
+
+00:05:48.360 --> 00:05:51.139
+I think it's) Xournal++
+
+00:05:51.200 --> 00:05:54.039
+I use the web quite a bit,
+
+00:05:54.040 --> 00:05:55.719
+especially if I want to just
+
+00:05:55.720 --> 00:05:57.759
+spontaneously look something up.
+
+00:05:57.760 --> 00:05:59.679
+Often I use video,
+
+00:05:59.680 --> 00:06:01.499
+especially molecular animations.
+
+00:06:01.500 --> 00:06:04.699
+And that's incredibly powerful.
+
+00:06:04.700 --> 00:06:06.939
+And then now and again, I want to look at text.
+
+00:06:06.940 --> 00:06:08.059
+Especially in
+
+00:06:08.060 --> 00:06:09.799
+the English course that I teach,
+
+00:06:09.800 --> 00:06:11.839
+there's quite a bit of text.
+
+00:06:11.840 --> 00:06:14.239
+I'll use Emacs for that.
+
+00:06:15.000 --> 00:06:18.439
+The video compositor, the thing that
+
+00:06:18.440 --> 00:06:22.479
+puts this video and me in the green screen.
+
+00:06:22.480 --> 00:06:25.419
+and all of this stuff together, is called
+
+00:06:25.420 --> 00:06:34.818
+OBS Studio—and that also does recording.
+
+00:06:34.820 --> 00:06:37.509
+It's ALMOST a completely free software stack.
+
+00:06:37.510 --> 00:06:38.749
+I use Zoom to do
+
+00:06:38.750 --> 00:06:39.929
+the streaming and video
+
+00:06:39.930 --> 00:06:41.029
+conferencing because all of
+
+00:06:41.030 --> 00:06:42.409
+the students are forced to use it for
+
+00:06:42.410 --> 00:06:44.218
+their other classes and
+
+00:06:44.220 --> 00:06:45.409
+I've gone along with it.
+
+00:06:45.410 --> 00:06:46.669
+But a good alternative is
+
+00:06:46.670 --> 00:06:48.858
+Jitsi Meet. There are others.
+
+00:06:48.860 --> 00:06:50.729
+Okay. Again, here's
+
+00:06:50.730 --> 00:06:53.789
+the hardware setup. On the tablet,
+
+00:06:53.790 --> 00:06:56.589
+I'm running Xournal++. On the laptop,
+
+00:06:56.590 --> 00:07:00.229
+I've got Firefox and VLC, and Emacs.
+
+00:07:00.230 --> 00:07:02.889
+OBS is compositing that together.
+
+00:07:02.890 --> 00:07:05.949
+And I use Zoom, but you could use Jitsi.
+
+NOTE Live demonstration
+
+00:07:05.950 --> 00:07:07.929
+All right, let's
+
+00:07:07.930 --> 00:07:09.689
+demonstrate this live. Here we go.
+
+00:07:09.690 --> 00:07:13.609
+Here goes, nothing. The drawing program
+
+00:07:13.610 --> 00:07:15.049
+is really good because I can draw
+
+00:07:15.050 --> 00:07:17.529
+with the stylus on a tablet.
+
+00:07:17.970 --> 00:07:20.089
+It's a remarkable thing—
+
+00:07:20.090 --> 00:07:22.409
+I teach in these big lecture halls,
+
+00:07:22.410 --> 00:07:24.409
+and I guess they want them to be fancy?
+
+00:07:24.410 --> 00:07:25.969
+And so they don't have blackboards and
+
+00:07:25.970 --> 00:07:29.009
+whiteboards! If I want to be able to draw,
+
+00:07:29.010 --> 00:07:32.169
+if I want to do anything approaching analog,
+
+00:07:32.170 --> 00:07:34.769
+it has to be with this software!
+
+00:07:35.290 --> 00:07:37.809
+In this presentation, I
+
+00:07:37.810 --> 00:07:39.489
+don't have very many diagrams,
+
+00:07:39.490 --> 00:07:41.509
+but in my courses, most of
+
+00:07:41.510 --> 00:07:44.249
+the slides are complicated diagrams.
+
+00:07:44.250 --> 00:07:45.809
+Being able to annotate them
+
+00:07:45.810 --> 00:07:47.549
+is really important.
+
+00:07:47.550 --> 00:07:50.629
+This is why I don't use Emacs for
+
+00:07:50.630 --> 00:07:54.529
+presenting these kinds of documents,
+
+00:07:54.530 --> 00:07:55.809
+because I want to be able
+
+00:07:55.810 --> 00:07:57.449
+to mark them up visually.
+
+00:07:57.450 --> 00:07:59.849
+I can show you what that looks like.
+
+NOTE OBS
+
+00:07:59.850 --> 00:08:02.829
+By the way, here's how OBS works:
+
+00:08:02.830 --> 00:08:04.469
+I can go from different "scenes"
+
+00:08:04.470 --> 00:08:06.069
+So I can just do just me,
+
+00:08:06.070 --> 00:08:08.129
+or I can show you the slides,
+
+00:08:08.130 --> 00:08:10.789
+or I can show you what I see on the tablet.
+
+00:08:10.790 --> 00:08:12.269
+On the tablet, I can go
+
+00:08:12.270 --> 00:08:14.229
+through all of the— notice here,
+
+00:08:14.230 --> 00:08:16.129
+I'm scrolling through all
+
+00:08:16.130 --> 00:08:17.349
+of the different slides.
+
+00:08:17.350 --> 00:08:19.989
+I've got all kinds of different markup tools,
+
+00:08:19.990 --> 00:08:23.169
+and tools for controlling
+
+00:08:23.170 --> 00:08:24.829
+zoom and what page I'm on,
+
+00:08:24.830 --> 00:08:27.189
+but you don't have to see that.
+
+NOTE Firefox
+
+00:08:27.190 --> 00:08:32.389
+Okay. Firefox, boy, I do a lot of this.
+
+00:08:32.390 --> 00:08:36.789
+All of the quizzes,
+
+00:08:36.790 --> 00:08:38.459
+quizzes and exams in my courses
+
+00:08:38.460 --> 00:08:40.129
+are online on this
+
+00:08:40.130 --> 00:08:43.369
+web platform called Canvas,
+
+00:08:43.370 --> 00:08:45.429
+which is good enough.
+
+00:08:45.430 --> 00:08:49.589
+It's based on a GPL3 package,
+
+00:08:49.590 --> 00:08:53.069
+but this one is proprietary for Penn State.
+
+00:08:53.070 --> 00:08:55.129
+Notice that there's a quiz
+
+00:08:55.130 --> 00:08:57.049
+every day, and this quiz,
+
+00:08:57.050 --> 00:08:59.469
+every quiz has a recording from
+
+00:08:59.470 --> 00:09:00.629
+that day and you notice
+
+00:09:00.630 --> 00:09:01.889
+there's a picture of me teaching,
+
+00:09:01.890 --> 00:09:05.029
+pointing to the slides.
+
+00:09:05.030 --> 00:09:06.969
+There's the slides themselves.
+
+00:09:06.970 --> 00:09:09.589
+I use OBS to composite in
+
+00:09:09.590 --> 00:09:12.769
+the Zoom chat because I teach this hybrid.
+
+00:09:12.770 --> 00:09:13.709
+There's people in the room
+
+00:09:13.710 --> 00:09:14.569
+and there's people at
+
+00:09:14.570 --> 00:09:17.629
+other campuses who are in this course.
+
+00:09:17.630 --> 00:09:19.389
+Having the Zoom chat in
+
+00:09:19.390 --> 00:09:22.649
+the live feed is very useful.
+
+00:09:22.650 --> 00:09:25.729
+Then the quiz—
+
+00:09:25.730 --> 00:09:26.669
+at the next class meeting,
+
+00:09:26.670 --> 00:09:27.889
+we'll go through this quiz.
+
+00:09:27.890 --> 00:09:30.049
+Here's some experimental data
+
+00:09:30.050 --> 00:09:31.649
+and here's a question where they're
+
+00:09:31.650 --> 00:09:36.589
+supposed to interpret these data.
+
+00:09:36.590 --> 00:09:38.849
+We can in class together,
+
+00:09:38.850 --> 00:09:41.629
+we can review those.
+
+00:09:41.630 --> 00:09:45.369
+That's why Firefox is useful.
+
+00:09:47.970 --> 00:09:50.569
+Being able to inhabit,
+
+00:09:50.570 --> 00:09:52.829
+being able to inhabit
+
+00:09:52.830 --> 00:09:56.869
+figures like this is incredibly powerful.
+
+00:09:56.870 --> 00:09:59.349
+This is the silver lining of being
+
+00:09:59.350 --> 00:10:02.129
+forced to teach online during the pandemic,
+
+00:10:02.130 --> 00:10:03.069
+because I couldn't do
+
+00:10:03.070 --> 00:10:05.759
+this before I had a green screen.
+
+00:10:05.760 --> 00:10:09.539
+But even more powerful than this—
+
+00:10:09.540 --> 00:10:10.819
+For years, I showed students
+
+00:10:10.820 --> 00:10:12.339
+this figure by standing in front
+
+00:10:12.340 --> 00:10:13.699
+of it or by having a
+
+00:10:13.700 --> 00:10:15.239
+projector screen above me.
+
+00:10:15.240 --> 00:10:18.459
+And I said, "This is the B form of DNA."
+
+00:10:18.460 --> 00:10:20.379
+"This is the most common form of DNA."
+
+00:10:20.380 --> 00:10:22.579
+"You see here that there's this minor groove."
+
+00:10:22.580 --> 00:10:23.419
+"And then this feature
+
+00:10:23.420 --> 00:10:24.419
+is called the major groove."
+
+00:10:24.420 --> 00:10:26.059
+And students couldn't see it.
+
+NOTE Animation
+
+00:10:26.060 --> 00:10:29.439
+But if you animate it—
+
+00:10:29.440 --> 00:10:30.279
+if you just have it
+
+00:10:30.280 --> 00:10:33.319
+move, the apparent movement,
+
+00:10:33.320 --> 00:10:34.399
+It's not really movement,
+
+00:10:34.400 --> 00:10:35.379
+it's apparent movement.
+
+00:10:35.380 --> 00:10:37.819
+And it tricks your visual cortex into
+
+00:10:37.820 --> 00:10:40.319
+adding three dimensional structure to this.
+
+00:10:40.620 --> 00:10:42.579
+You can see this feature is
+
+00:10:42.580 --> 00:10:45.339
+the major groove and that feature
+
+00:10:45.340 --> 00:10:47.219
+is the minor groove. And a static
+
+00:10:47.220 --> 00:10:48.319
+image just can't provide
+
+00:10:48.320 --> 00:10:51.399
+that understanding, while moving image can.
+
+NOTE Emacs
+
+00:10:55.790 --> 00:10:58.179
+I use Emacs to look at text.
+
+00:10:58.180 --> 00:11:02.519
+Where's Emacs? Here's Emacs! We read
+
+00:11:02.520 --> 00:11:04.279
+Vonnegut in this English class that I
+
+00:11:04.280 --> 00:11:07.759
+teach and I'm going to tab over to Emacs.
+
+00:11:07.760 --> 00:11:09.859
+It's nice to be able
+
+00:11:09.860 --> 00:11:12.419
+to have text jump
+
+00:11:12.420 --> 00:11:14.159
+around and be dynamic, right?
+
+00:11:14.160 --> 00:11:16.859
+If you, if you want to look
+
+00:11:16.860 --> 00:11:18.039
+at this passage and I'll
+
+00:11:18.040 --> 00:11:19.259
+have somebody read it aloud.
+
+00:11:19.260 --> 00:11:20.819
+And then we talk about why he chose
+
+00:11:20.820 --> 00:11:22.499
+this word and why he chose that word,
+
+00:11:22.500 --> 00:11:25.179
+and the cadence, and the alliteration.
+
+00:11:25.180 --> 00:11:30.839
+Then we can go to another particular excerpt
+
+00:11:30.840 --> 00:11:33.439
+and pick that apart on the screen together.
+
+00:11:33.440 --> 00:11:34.899
+That would be difficult to do with
+
+00:11:34.900 --> 00:11:36.819
+other software that would be very tedious
+
+00:11:36.820 --> 00:11:39.399
+to do on the chalkboard.
+
+00:11:39.400 --> 00:11:42.259
+So Emacs is really good for that sort of thing.
+
+NOTE Making slides and handouts with Org Mode
+
+00:11:42.260 --> 00:11:45.379
+Mostly what I use Emacs for is not to
+
+00:11:45.380 --> 00:11:50.339
+present but to make slides and handouts.
+
+00:11:50.340 --> 00:11:52.359
+Okay. Again, the thing that I want to
+
+00:11:52.360 --> 00:11:54.219
+stress is that the slides
+
+00:11:54.220 --> 00:11:56.739
+and the handouts can be produced from
+
+00:11:56.740 --> 00:12:01.179
+a single Org mode document.
+
+00:12:01.180 --> 00:12:04.059
+This entire presentation
+
+00:12:04.060 --> 00:12:05.699
+was assembled in Emacs.
+
+00:12:05.700 --> 00:12:07.939
+I'll show you how I did that.
+
+00:12:08.420 --> 00:12:11.619
+I think everybody
+
+00:12:11.620 --> 00:12:13.159
+probably knows what Org mode is.
+
+00:12:13.160 --> 00:12:14.639
+But for our purposes, it's a way
+
+00:12:14.640 --> 00:12:16.119
+to write documents in plain text.
+
+00:12:16.120 --> 00:12:19.839
+That's very important because one of
+
+00:12:19.840 --> 00:12:22.019
+the biggest advantages of this is
+
+00:12:22.020 --> 00:12:24.739
+being able to do version control.
+
+00:12:24.740 --> 00:12:27.779
+I don't have Powerpoint decks
+
+00:12:27.780 --> 00:12:29.359
+everywhere with slides that
+
+00:12:29.360 --> 00:12:31.239
+there's no way to keep track of them.
+
+00:12:31.240 --> 00:12:32.459
+Having these be plain text
+
+00:12:32.460 --> 00:12:33.579
+means that I can just put them in
+
+00:12:33.580 --> 00:12:36.139
+a git repository.
+
+00:12:36.140 --> 00:12:37.899
+Very clean and human readable markup
+
+00:12:37.900 --> 00:12:41.159
+including handling tables
+
+00:12:41.160 --> 00:12:43.339
+which is just incredibly powerful.
+
+00:12:43.340 --> 00:12:45.459
+You can manage projects and tasks.
+
+00:12:45.460 --> 00:12:47.299
+But the fact that it's an outline
+
+00:12:47.300 --> 00:12:48.979
+that you can produce a document that's
+
+00:12:48.980 --> 00:12:51.279
+hierarchical and fold and
+
+00:12:51.280 --> 00:12:52.979
+reveal different parts of it.
+
+00:12:52.980 --> 00:12:57.119
+But to produce a book length lectures for
+
+00:12:57.120 --> 00:12:58.919
+an entire semester and use
+
+00:12:58.920 --> 00:13:01.399
+those to produce both slides and handouts,
+
+00:13:01.400 --> 00:13:03.179
+that's very powerful,
+
+00:13:03.180 --> 00:13:04.999
+at least for my brain. To be able to
+
+00:13:05.000 --> 00:13:06.779
+put it all together and have it be
+
+00:13:06.780 --> 00:13:08.399
+discursive rather
+
+00:13:08.400 --> 00:13:09.919
+than having to be graphical.
+
+00:13:09.920 --> 00:13:11.879
+You can export to
+
+00:13:11.880 --> 00:13:15.059
+a million different formats including
+
+00:13:15.060 --> 00:13:16.999
+PDF documents like the handouts as
+
+00:13:17.000 --> 00:13:22.679
+LaTeX, and slides like these through Beamer export.
+
+NOTE Pedagogy first
+
+00:13:22.680 --> 00:13:24.919
+The approach is to think
+
+00:13:24.920 --> 00:13:26.899
+about pedagogy rather than thinking
+
+00:13:26.900 --> 00:13:28.279
+about software or thinking
+
+00:13:28.280 --> 00:13:30.999
+about graphic design.
+
+00:13:31.000 --> 00:13:32.599
+To think about how can
+
+00:13:32.600 --> 00:13:34.379
+I make the best argument?
+
+00:13:34.380 --> 00:13:35.979
+How can I make the best,
+
+00:13:35.980 --> 00:13:40.879
+the most effective sequence of ideas?
+
+00:13:40.880 --> 00:13:44.999
+All I've done is make a few tweaks to
+
+00:13:45.000 --> 00:13:47.979
+the export backends for LaTeX and
+
+00:13:47.980 --> 00:13:49.979
+Beamer to customize them
+
+00:13:49.980 --> 00:13:51.499
+for my particular needs.
+
+00:13:51.500 --> 00:13:54.599
+And I'll show you what I've done.
+
+00:13:54.600 --> 00:13:58.059
+You've seen this already. I'll put
+
+00:13:58.060 --> 00:14:00.899
+one idea in big text on the screen.
+
+00:14:00.900 --> 00:14:04.619
+I find it to be effective to
+
+00:14:04.620 --> 00:14:09.119
+make a single idea explicit at one time.
+
+00:14:09.120 --> 00:14:12.259
+Now, some concepts can
+
+00:14:12.260 --> 00:14:14.799
+be explained with words or text,
+
+00:14:14.800 --> 00:14:20.259
+but many ideas are best just illustrated.
+
+00:14:20.260 --> 00:14:22.539
+In contrast, we've
+
+00:14:22.540 --> 00:14:23.979
+all used Powerpoint, right?
+
+00:14:23.980 --> 00:14:25.699
+And Edward Tufte has taught us
+
+00:14:25.700 --> 00:14:27.479
+about how Powerpoint is so
+
+00:14:27.480 --> 00:14:29.239
+terrible from a cognitive point of
+
+00:14:29.240 --> 00:14:31.799
+view and from a communications point of view.
+
+00:14:31.800 --> 00:14:35.398
+So using Org mode is much better.
+
+00:14:35.400 --> 00:14:36.759
+How is it better?
+
+00:14:36.760 --> 00:14:41.479
+Well, Tufte also tells us that
+
+00:14:42.040 --> 00:14:49.049
+any oral presentation that is substantive at all
+
+00:14:49.050 --> 00:14:52.629
+has to have some physical handout
+
+00:14:52.630 --> 00:14:55.709
+that the audience can use to take notes on.
+
+00:14:55.710 --> 00:14:58.749
+Slides are terrible handouts.
+
+00:14:59.030 --> 00:15:02.129
+And notes are usually terrible slides.
+
+00:15:02.130 --> 00:15:03.689
+Having one document where you
+
+00:15:03.690 --> 00:15:05.849
+can produce both and have them be,
+
+00:15:05.850 --> 00:15:08.409
+have the same organization,
+
+00:15:08.410 --> 00:15:10.349
+but different structures and
+
+00:15:10.350 --> 00:15:14.749
+different visual organization is
+
+00:15:14.750 --> 00:15:16.609
+something that I wanted
+
+00:15:16.610 --> 00:15:18.629
+for a long time and I can only do it
+
+00:15:18.630 --> 00:15:20.019
+with Emacs.
+
+00:15:20.020 --> 00:15:21.409
+Being able
+
+00:15:21.410 --> 00:15:22.729
+also for my brain to
+
+00:15:22.730 --> 00:15:25.309
+separate the work of writing and developing
+
+00:15:25.310 --> 00:15:28.469
+ideas and developing explanations
+
+00:15:28.470 --> 00:15:30.049
+and developing arguments
+
+00:15:30.050 --> 00:15:31.429
+and scaffolding them.
+
+00:15:31.430 --> 00:15:33.689
+That's jargon in pedagogy
+
+00:15:33.690 --> 00:15:36.889
+for bringing the student along.
+
+00:15:36.890 --> 00:15:41.349
+Separate that work from wrangling slides.
+
+00:15:41.350 --> 00:15:44.529
+That's super helpful for me.
+
+00:15:44.530 --> 00:15:46.709
+Again, you have
+
+00:15:46.710 --> 00:15:48.229
+an Org document that makes
+
+00:15:48.230 --> 00:15:51.369
+both the handouts and the slides.
+
+00:15:51.370 --> 00:15:53.449
+What's beautiful about it is
+
+00:15:53.450 --> 00:15:54.649
+that everything is an outline.
+
+00:15:54.650 --> 00:15:56.429
+And again, it's very discursive.
+
+00:15:56.430 --> 00:15:59.109
+Here's Tufte's famous poster where he's making
+
+00:15:59.110 --> 00:16:02.009
+fun of the psychology of Powerpoint.
+
+00:16:02.010 --> 00:16:05.749
+I don't know about you, but I have the kind of brain
+
+00:16:05.750 --> 00:16:07.609
+and I'm in the kind of job
+
+00:16:07.610 --> 00:16:09.909
+and I'm at the age where I don't have extra
+
+00:16:09.910 --> 00:16:12.049
+cognitive function! You know?
+
+00:16:12.050 --> 00:16:15.729
+So streamlining this workflow
+
+00:16:15.730 --> 00:16:17.789
+has been really helpful.
+
+NOTE org-teach
+
+00:16:17.790 --> 00:16:19.309
+All right, so let me show
+
+00:16:19.310 --> 00:16:21.649
+you what I've developed.
+
+00:16:21.650 --> 00:16:24.489
+Let's look at the Org doc.
+
+00:16:24.490 --> 00:16:25.829
+Okay. So what you see is you have
+
+00:16:25.830 --> 00:16:30.769
+a typical Org mode buffer.
+
+00:16:30.770 --> 00:16:32.849
+There's two headings here.
+
+00:16:32.850 --> 00:16:35.529
+One of them is stuff that I've deleted and
+
+00:16:35.530 --> 00:16:39.269
+the other is the talk.
+
+00:16:39.270 --> 00:16:43.109
+And so all of these subheadings have
+
+00:16:43.110 --> 00:16:46.389
+various things underneath including
+
+00:16:46.390 --> 00:16:48.969
+these macros that I wrote like `include-slide`,
+
+00:16:48.970 --> 00:16:51.229
+`impact-slide`, `subsection-slide`,
+
+00:16:51.230 --> 00:16:54.909
+et cetera, and then a bunch of stuff.
+
+00:16:54.950 --> 00:16:59.309
+Then I've got this include
+
+00:16:59.310 --> 00:17:01.629
+file that just has
+
+00:17:01.630 --> 00:17:03.289
+the macros that I've written.
+
+00:17:03.290 --> 00:17:05.449
+You can look at this on the repo.
+
+00:17:05.450 --> 00:17:06.289
+I'm not going to take
+
+00:17:06.290 --> 00:17:07.569
+the time to walk through it and
+
+00:17:07.570 --> 00:17:10.369
+explain what all the LaTeX means.
+
+00:17:10.370 --> 00:17:16.509
+But the upshot is
+
+00:17:16.510 --> 00:17:20.549
+that by including that file
+
+00:17:20.550 --> 00:17:22.429
+that has all the macro definitions,
+
+00:17:22.430 --> 00:17:25.649
+you get things like this macro pause
+
+00:17:25.650 --> 00:17:27.689
+or newline or whitespace-break,
+
+00:17:27.690 --> 00:17:30.809
+which just allow—
+
+00:17:30.810 --> 00:17:33.009
+pause splits a slide into two frames,
+
+00:17:33.010 --> 00:17:34.569
+so you can get these overlays,
+
+00:17:34.570 --> 00:17:36.309
+so you can go through paragraphs one by one.
+
+00:17:36.310 --> 00:17:38.629
+These just put
+
+00:17:38.630 --> 00:17:42.649
+white space in.
+
+00:17:44.650 --> 00:17:47.109
+Text-slides: This thing here, this title
+
+00:17:47.110 --> 00:17:49.169
+is level three heading.
+
+00:17:49.170 --> 00:17:50.189
+Figure-slides:
+
+00:17:50.190 --> 00:17:52.049
+the same thing are level three headings.
+
+00:17:52.050 --> 00:17:54.009
+One of the most powerful things
+
+00:17:54.010 --> 00:17:56.229
+is that I can take other files,
+
+00:17:56.230 --> 00:18:00.149
+I can take other Org files that have level
+
+00:18:00.150 --> 00:18:02.789
+three headings that are slides and those can
+
+00:18:02.790 --> 00:18:06.209
+be in some other repository.
+
+00:18:06.210 --> 00:18:08.509
+I only need to have one version of
+
+00:18:08.510 --> 00:18:09.909
+that slide that I
+
+00:18:09.910 --> 00:18:12.749
+can use in multiple courses.
+
+00:18:13.230 --> 00:18:17.109
+Just that functionality is
+
+00:18:17.110 --> 00:18:19.909
+incredibly helpful for keeping
+
+00:18:19.910 --> 00:18:22.809
+track of work from a few years ago.
+
+00:18:22.810 --> 00:18:24.269
+All of these I'm going to
+
+00:18:24.270 --> 00:18:25.929
+explain in the next few slides.
+
+00:18:25.930 --> 00:18:27.709
+The section slides
+
+00:18:27.710 --> 00:18:29.909
+correspond to course modules.
+
+00:18:29.910 --> 00:18:31.129
+Each of these is going to
+
+00:18:31.130 --> 00:18:32.549
+be a few weeks of a course.
+
+00:18:32.550 --> 00:18:34.629
+This is a major division of a course.
+
+00:18:34.630 --> 00:18:36.909
+I have some macros so that I can decorate
+
+00:18:36.910 --> 00:18:41.389
+this with relevant information.
+
+00:18:41.390 --> 00:18:43.469
+Then for every subsection,
+
+00:18:43.470 --> 00:18:45.569
+level two headline, that
+
+00:18:45.570 --> 00:18:46.729
+corresponds to a major
+
+00:18:46.730 --> 00:18:48.589
+course topic in the module.
+
+00:18:48.590 --> 00:18:50.209
+Then text slides, again,
+
+00:18:50.210 --> 00:18:52.849
+level three headlines become
+
+00:18:52.850 --> 00:18:53.969
+titles for the slide,
+
+00:18:53.970 --> 00:18:58.859
+and level four headlines become text elements.
+
+00:18:58.900 --> 00:19:01.679
+Most of my slides look like this.
+
+00:19:01.680 --> 00:19:03.139
+They're figures.
+
+00:19:03.140 --> 00:19:05.859
+Here's the glycolytic pathway.
+
+00:19:06.020 --> 00:19:09.979
+Level three gives you the title.
+
+00:19:11.420 --> 00:19:14.279
+It's missing here actually,
+
+00:19:14.280 --> 00:19:16.719
+but there's a way you can put in captions.
+
+00:19:16.720 --> 00:19:18.959
+This line here just tells
+
+00:19:18.960 --> 00:19:21.039
+the LaTeX export backend
+
+00:19:21.040 --> 00:19:24.219
+how big you want it and stuff like that.
+
+00:19:24.220 --> 00:19:29.139
+Impact slides, they have to go under H1 or H2.
+
+00:19:29.140 --> 00:19:32.179
+And they just give you one of these text slides.
+
+00:19:32.450 --> 00:19:35.649
+For an entire slide being an image,
+
+00:19:35.650 --> 00:19:38.249
+you can use this image-slide macro.
+
+NOTE Blank slides
+
+00:19:38.330 --> 00:19:41.129
+I often put in blank slides to
+
+00:19:41.130 --> 00:19:43.269
+remind myself that this is a time to stop.
+
+00:19:43.270 --> 00:19:44.789
+Often there's something for me to
+
+00:19:44.790 --> 00:19:47.369
+draw here with the stylus.
+
+NOTE Animations
+
+00:19:50.050 --> 00:19:53.149
+I often use— it used to be Powerpoint,
+
+00:19:53.150 --> 00:19:56.069
+now I use LibreOffice Impress—to make
+
+00:19:56.070 --> 00:19:58.309
+multi slide animations like
+
+00:19:58.310 --> 00:20:01.309
+the sphere and the donut and the GI tract.
+
+00:20:01.310 --> 00:20:03.249
+And this hardware thing
+
+00:20:03.250 --> 00:20:05.269
+that I did for you today,
+
+00:20:05.270 --> 00:20:07.949
+I export those animations as PDFs.
+
+00:20:07.950 --> 00:20:14.469
+Then I can just slurp them up into the slides.
+
+00:20:14.470 --> 00:20:16.669
+Just into the slides, not into
+
+00:20:16.670 --> 00:20:19.269
+the handouts with this macro.
+
+NOTE Conclusion
+
+00:20:19.270 --> 00:20:21.489
+I hope that you find this useful.
+
+00:20:21.490 --> 00:20:22.449
+I hope you share it with
+
+00:20:22.450 --> 00:20:24.089
+other educators that you know.
+
+00:20:24.090 --> 00:20:27.149
+Here is the sourcehut repo,
+
+00:20:27.150 --> 00:20:29.069
+here's how to get in touch with me.
+
+00:20:29.070 --> 00:20:32.569
+I look forward to addressing your questions.
+
+00:20:32.690 --> 00:20:34.989
+I want to say thank you
+
+00:20:34.990 --> 00:20:36.609
+to Sacha [Chua] and the organizers,
+
+00:20:36.610 --> 00:20:38.449
+and to everyone who made this possible and
+
+00:20:38.450 --> 00:20:40.689
+to all of you in the community.
+
+00:20:40.690 --> 00:20:42.769
+Because as we all know,
+
+00:20:42.770 --> 00:20:47.429
+that that's what makes Emacs such a strong
+
+00:20:47.430 --> 00:20:50.089
+and powerful package is
+
+00:20:50.090 --> 00:20:51.329
+all of the people behind it.
+
+00:20:51.330 --> 00:20:53.169
+Thanks everybody.
