Giving a lightning talk at BugBash 2026 this April. Ridiculous speaker lineup. very honored to be part of it! bugbash2026.antithesis.com

just spoke at [un]prompted.
@dguido talked about shipping 200 bugs/week/engineer.
nicholas carlini talked about LLMs finding 0-days in production code.
i talked about how a 3-integer baseline was embarrassingly hard to beat on 125K kernel commits, and what that means for actually building systems that work.
clip from the Q&A below ↓
the 125K commit dataset behind the talk:
→ bugs that hide for years: pebblebed.com/blog/kernel-bu…
→ who actually writes them: pebblebed.com/blog/kernel-bu…

Analysis of the Linux kernel bugfixes
@GuanniQu posted a detailed analysis:

hosting a girls' night dinner at pebblebed this saturday in sf @ 7pm
casual dinner for women in tech. founders, engineers, friends. food provided.
sf's gender ratio is famously bad. this dinner won't fix it, but it's a start.
forward this to your girls or tag them below 👇

kernel testing is uniquely hard. you need real hardware across architectures, specialized sanitizers and static analysis tools, tribal knowledge for BPF tests, and bisection = recompile + reboot at every step. pre-merge CI exists (Intel 0-Day, KernelCI) but coverage is inconsistent. many subsystems still have little to no automated testing

@MaxNiederman fair, but hoping for a warning shot is a weird strategy when the warning shot might just keep shooting…

@GuanniQu Most people threat modeling superintelligence actually want that attack to happen as a warning shot.

another issue with the linux mailing list workflow: patches don't specify what tree they're based on. you get a diff, try to apply it, context lines don't match, patch fails. mainline? net-next? some -rc? git format-patch --base=auto exists but isn't standard practice. maintainers guess, ask, or skip
