The Intel 8086 was released in 1978, starting the x86 line that still dominates computing. I'm reverse-engineering the chip by studying the silicon die, and I think I've spotted a bug fix in the silicon. They didn't have microcode updates then so they patched the silicon. 🧵

You've all been asking for it, and Asahi Lina / 朝日リナ 🐘 @[email protected] 🦋 @lina.yt's GPU article is finally here! ✨ Tales of the M1 GPU: asahilinux.org/2022/11/tales-…

We recently found a vulnerability affecting Hyundai and Genesis vehicles where we could remotely control the locks, engine, horn, headlights, and trunk of vehicles made after 2012. To explain how it worked and how we found it, we have ꙅɿɘƚɔɘqꙅ as our mock car thief:
