    Sad that your CPU is broken? These microarchitectures were advertised as "Out-of-Order" from the very beginning.

    1/7 Did you ever need to run a piece of C# code on Windows 3.11? Me neither, but I did it anyway. A thread.

    Just blame AI for every shitty decision. Perfect plausible deniability

    I'm also not a big fan of obfuscation and encryption of code. Makes it harder to audit for small companies/junior researchers working in good faith. Does little for security and IP protection against well funded labs.

    I'd like to thank everybody working on RustPkg () and hope that it will get out of staging and adopted by IBVs and OEMs alike, as after 20 years of writing security-critical system software in C, it's finally time to switch to a safer better tools.

    New blogpost: Sanitized Emulation with QEMU-AddressSanitizer I just open-sourced my QEMU patches to fuzz binaries with ASan, QASan. You can also use it with ARM targets on Linux, a thing that you can't do with LLVM ASan!

    The synchronizer knows what the signal is at all times. It knows this by knowing what it isn't. By passing a signal through a flip flop it obtains a signal that is not. And it follows that a signal that is not now is.

    Many things have gone wrong with the cyberpunk dream, but the ability to instantly download a scientific paper from a sketchy website in Russia is probably the best thing we still have.

    This is one of most noncommittal APIs to ever exist. It’s impressive.

    Linux does not treat every memory corruption as a CVE so they don't get backported. Additionally, even if Android used vanilla tree,it would use LTS,not mainline.Fix backports would still be missed. OTOH,binder's the only non-SoC driver without SELinux.G should track it manually

    Galaxy brain: only allow TZ/SMM on "little" cores. What could be done for regular OS (Linux)? A scheduler policy to keep tasks as long as possible? Decrease HZ? I wonder how that perf/interactivity loss compares against less TLB/BP flushing.
