As much as I hate it, there's currently still available a thread on Reddit that provides links to various archives of January 6th info/video/etc. I personally have the 1~ TB video archive data saved and mirrored on a couple of cold storage drives and I'd encourage anyone with the extra HDD space to grab as much as you can while it's there.

There really isn't any decent Linux support for anything beyond the basic 5 button mouse without use of 3rd party apps. Even the "name brands" suffer from mass market shitty build quality that negates any "linux compatible" bonus points.
Then there's the issue of the mouse hardware itself. Good luck finding an "MMO Mouse" that correctly reports every button as it's own input. Which makes the whole "Just remap it, it's an HID" aspect annoying. Redragon seems especially guilty in this area.
