AI vulnerability/bug founds and reports is a huge problem. Curl has banned the use of AI-generated submissions via HackerOne because none of it made any sense, and is a waste of resources and time. "If we could, we would charge them for this waste of our time" hackerone.com/reports/3125...

Here's another set of great addons from our David Schwarz (aka @prusaguy.bsky.social) to customize your Prusa CORE One.🦾 If having the spool outside the printer doesn't suit your setup - we bring you the "Prusa Core One Internal Spool Holder".

Trying to get back into doing some livestreams, it seems I need to polish my audio + video setup again. Also it seems OBS Studio also has changed quite a bit. Not yet decided about the content, but I guess it will be a mix of 3d print development/tuning, reverse engineering and forensics content. 😉

Thinking about making a livestream about trying to recover a fat32 filesystem from an old japanese phone to recover the games, using in-depth techniques like disassembly of BMR/Wearleveling and FAT32 structures. What do you guys think ?
