I thought this was going to be a stream showing what their web crawler was doing (showing the sites/pages it's archiving, etc), which would've been really cool to me... But getting to see an inside view of the Internet Archive doing any of their preservation work is also cool, of course :)

Pipewire, Wayland, Matrix.

Definitely display-buffer-alist for me. I was using purpose-mode for the longest time but I think I finally managed to get display-buffer-alist working mostly how I want.

Arcan maybe?

There's also ollama which seems to be similar. Not sure if LMStudio is open source but ollama is.
