My vectorized sorting extravaganza is out and about. A LOT of work went into this (referring to the javascript in the posts :) Read, retweet, send scathing reviews, open issues, heat your house with it: This goes to Eleven! Pt. 1-3, code, nuget out:https://bits.houmus.org/2020-01-28/this-goes-to-eleven-pt1 …

I've been informed by my blog review team (population count: 1) in no uncertain terms that I should either budget adult diapers for my readership, or split pt. 4 into 3 more parts. Given Damage Open Source Industries' dire financial circumstances, I'm choosing the latter :)

Ok, listen. If you're interested in high-performance and optimized code, do yourself a favor and read these posts where
@damageboy explains how he optimized the hell out of array sorting using AVX2 in C#. It's clear, approachable and has great visualizations.https://twitter.com/damageboy/status/1222769382394343424 …Show this threadThanks. Twitter will use this to make your timeline better. UndoUndo -

If you liked
@stevejgordon 's excellent perf talk at#NDCLondon. You should also check out@damageboy 's work on sort optimisation using intrinsics:https://bits.houmus.org/2020-01-28/this-goes-to-eleven-pt1 …Thanks. Twitter will use this to make your timeline better. UndoUndo -
I know it sounds weird, but the thing I'm most excited about pt.4 of my series is the chance to finally tell the story of my most spectacular failure that cost me maybe two weeks of my nights... The lesson I learned from it about CPUs is one I'm most eager to share with you all.

I think I just realized that no C# compiler/IDE combo produces a "redundant generic type constraint" warning/analysis... Am I missing something? /cc:

Finally, the disclosure is over! We present CacheOut, a new speculative execution attack to leak data on Intel CPUs via cache eviction despite current mitigations: https://cacheoutattack.com

Yet another C quiz! Can you tell the output just by looking at the code? int main(void) { fork(); putchar('x'); fork(); return 0; } gcc prog.c && ./a.out Assume standard up to date Linux glibc implementation.

To be fair everyone underappreciates this to very high degree. It IS the hardest business to run, from the little friends I have that do/did it. They need to deal with shit that would completely end me on a daily basis. https://twitter.com/HoldenthePage/status/1220710886110908421 …
