Notes, discussions, links, feedback:
- Download the handout (27MB PDF):
- The whole repository: https://git.sr.ht/~jamesendreshowell/org-teach
- Resolution kinda low.
- No, sorry! It was the best I was able to record.
- 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?
- 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. 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
- 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
----------------------------------------------------------------
Questions and answers go here:
- 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 talk🙏)
- 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.
- Thank you very much, I'll definitively look into this🙏
- 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? Correct?
