With GNU Emacs at the center of these +workflows? It's not only possible, it's much more flexible and empowering than being locked into proprietary platforms. We will step through the +entire software stack and workflows for authoring and presenting lessons, authoring and evaluating assessments, and engaging students both in +person and in fully online teaching environments. + +About the speaker: + +James Endres Howell has taught Molecular and Cell Biology, +Biochemistry, Microbiology, Immunology, Toxicology, and Molecular +Medicine at Penn State since 2006. Recently Dr. Howell has developed +popular courses for non-science majors in Genetics, Ecology and +Evolution; Science in Literature; and Science in Society. He has used +Emacs daily since 1988. + +# Discussion + +## Notes + +- I'm digging the weather-report style with your pointing at the screen :) +- I'm using org-mode to study for exams rather than present lectures recently btw. I like to copy questions in the org file and add notes as I work through the questions on paper. +- Q: do you use org-present or something like that? + - A: Nope, just a normal Org buffer. I have a few custom keybindings for narrowing to headlines and such, when I do use Emacs for presenting. (Coming up in a few slides) +- Next step: libre hardware :) +- ahh he broke the fourth...fifth?...wall! :) +- bookmarking xournal+++ for sure +- Living dangerously now. :-) +- he's definitely a wizard! +- OBS looks very useful. Must explore. +- I had never thought of using OBS for presentations like that... this has to be the slickest setup there is +- my students all seem to come to class with tablets these days and they annotate the PDF of all of my slides. When I realised they were doing this, I decreased the density of material on each slide to ensure there was enough space for their notes. +- macros are a very powerful and useful feature of org for complex documents! + +- Feedback +- Damn, this looks really really useful +- This presentation is damn cool, LOL. +- excellent talk! Thank you. +- Thanks for the talk, it was very interesting!! +- Fantastic. I think this talk will be a reference for years to come! +- Great stuff! +- You are one of my heroes now! πππππ +- Brilliant talk James, inspiring stuff +- Great system! + + + + +- Download the handout (27MB PDF): + - <https://git.sr.ht/~jamesendreshowell/org-teach/blob/master/EmacsConf_2023_Howell_handout.pdf> +- The whole repository: + <https://git.sr.ht/~jamesendreshowell/org-teach> +- Resolution kinda low.Β + - No, sorry! It was the best I was able to record. + - okay, it's fine. +- OBS is cool. +- I use pdfpc (can also present and draw, but command line) - + <https://pdfpc.github.io/> + - Also, pdfpc supports videos/animations in presentations :) + - Hm! I will look into it! +- Kinda mute? + - I don't know why! +- On publishing lectures/books - another classic example is John + Kitchin's <https://github.com/jkitchin/dft-book> + - Kitchin is a monster! He must have made a deal with the devil or + something. + - I suspect that it is what Assistant Prof position does to + people +- Pedagogy first "development" + - Materials must provide a way to take notes on + - Separate the work of writing/developing/scaffolding from slide + wrangling + - THe org-teach allows for grabbing a slide from another + repository (e.g. don't repeat knowledge) +- If you want to highlight org mode documents you can use + <https://github.com/nobiot/org-remark>. If you use Org Remark with + <https://github.com/alphapapa/org-web-tools> you can get an offline + backup af a web page that you can highlight and edit + - Wow. I will look into these. +- Macros are a cool idea! + - Are org-mode macros a new concept/learning for you? + - Surely not (I am a contributor). But it is a new idea to use + them for beamer presentations. + - Yeah, I loved see other ways folks use macros.Β I've + done some of that for Beamer, but only recently. +- I use org-transclusion + (<https://github.com/nobiot/org-transclusion>) for include other + document. + - It sounds like the include other file might be for including + non-org-mode files; does org-transclusion provide that + functionality? + - yep~, quit powerful. + - :) + - opps, I double check the manual. It seems mainly for + human readable source code (txt, md, source code). I + don't think it works with Pdf ... +- OBS TIP -- You can use an android app like OBS Blade to control obs + from android + - Cool, thanks! +- CRDT.el <https://code.librehq.com/qhong/crdt.el> -- This can allow + multiple people with thier own Emacs Configs to edit a hosted emacs + buffer at the same time + - Awesome + +## Questions and answers + +- Q: I'm curious how the xournal stylus work is composited with OBS +- Q: that entire screen was xournal at the time? I was thinking the slide was a different screen / software + - A: All the slides are presented via Xournal++. The "slides" frame is video capture from the tablet, running Xournal++. +- Q: Do you have a fancy OBS scene changer to switch between the software being presented? + - A: I just map scenes to function keys on the keyboard. +- Q: How you overlap yourself with the presenation? It's so cool. + - A: OBS provides a chroma key "filter" + - it's so cool! with DNA demo. +- Q: How you deal with Video in Beam? I found it's so hard to do + that. PPT on the other hand is so easy to achieve. + - A: I use Beamer export to make static slides, that I present via + Xournal++. Videos, I present via VLC. So I use OBS to switch + back and forth between Xournal, VLC, Firefox, etc. + - The above-mentioned pdfpc provides a LaTeX package to link + videos right to pdf (battle-tested on conferences ;)) + - Thanks, I will have a try. + - Thank you! +- Q: Do you ever use things like Org Presnet and stay forgo powerpoint + slidees + - A: I've tried them but my core need is to annotate PDFs with + the stylus in real time, so the best solution is Xournal++ +- Q: Is the {{{ }}} syntax an Org Mode core feature that I have missed + so far, or did you program that? (Btw, thank you for the great + talkπ) + - A: <https://orgmode.org/manual/Macro-Replacement.html> + - Some export backends allow for conditionals in the macro + replacement; when exporting to Hugo you can add an @@hugo + within the resolved macro. + - @@backend:...@@ is a separate construct - you do not + have to use it in combination with macros. For example, + see @@html example in + <https://orgmode.org/manual/Quoting-HTML-tags.html> + - Thank you very much, I'll definitively look into thisπ +- Q: What kind of (comparative) feedback are students giving you + regarding your approach? + - A: They love it! All accounts were that my courses were much + more successful than other instructors'. +- Q: You also teach English at Uni? cool + - A: Yes, it's a fun course. +- Q: Is the input from the Surface captured by OBS and all of that + combined goes to Jitsi or Zoom?
