Cool: [Wayback/Archive] bitfocus/companion: Bitfocus Companion enables the reasonably priced Elgato Streamdeck to be a professional shotbox surface for an increasing amount of different presentation switchers, video playback software and broadcast equipment.

[Wayback/Archive] What Every Programmer Should Know about How CPUs Work • Matt Godbolt • GOTO 2024 – YouTube

Main takeaways for me:

“The Pocket Guide to Debugging” zine and Debugging Puzzels by b0rk (Julia Evans)

Posted by jpluimers on 2025/09/10

I forgot scheduling this post, but it is still very relevant: about the debugging related materials by b0rk (Julia Evans) as they are not limited to just “The Pocket Guide to Debugging”.

I thought I had been living under a stone for decades when I bumped into vx-underground (@vxunderground) / Twitter

The largest collection of malware source code, samples, and papers on the internet.

Password: infected

That appeared to be untrue as vx-underground, ran by a team of volunteers, started in 2019 ([Archive] web.archive.org/web//vx-underground.org) right when a few crisis in my life came together at the same time.

So here are the links for my archive as they are great content for both Red Teams and Blue Teams on many things cyber security related:
