Description

Modern graphics with Emacs with hardware/software acceleration

This video has no narration.

  • https://dataswamp.org/~incal/tmp/greeting.webm

  • https://dataswamp.org/~incal/tmp/kitty-vt.webm shows the software can be used from a -nw Emacs

  • didn't expect to see demos today

  • I was reminded of the demo scene by this presentation. https://scene.org/
  • does the demo show its code at some point?
    • It doesn't :/
    • https://dataswamp.org/~incal/bad-www/index.html
  • this has more than when I previewed it last. Wow!
  • So how to download the source from https://dataswamp.org/~incal/bad-el/src/ ?

  • maybe he likes to be mysterious

  • Q:So how to download the source from that site?

    • A: there is a link to src/ maybe I can do a tar ball for y'all. if so I'll put it in that dir
    • wget use -e robots=off if robots are a problem
    • https://dataswamp.org/~incal/bad-el/src/bad-el.tar.gz <-- there is a tarball you can download now.
  • Q: How do you get into demomaking?
    • A: never thought of it that way. is it different from other programming?
