4. Zigzag Decoding with AVX-512 (zeux.io)

I’ve been working on speeding up AVX-512 vertex decoding in meshoptimizer recently; in the process I stumbled upon two optimizations that I did not end up using but I thought they might be fun to write about! The optimizations that actually made it in require some higher level background / explanations that will have to wait until another day :)

16. AI Has Broken Hiring (hbr.org)

Generative AI is rapidly undermining the reliability of traditional hiring signals, making it easier for candidates to manufacture polished résumés and perform convincingly in remote interviews with real-time assistance tools. Interviews with 120 talent-acquisition leaders and an analysis of more than 6,000 screening sessions show that companies now risk selecting for candidates who are best at navigating the hiring process rather than best equipped to do the job. To adapt, organizations must redesign early-stage hiring around authentic reasoning, judgment, and adaptability instead of static credentials and scripted interviews.

We found that Claude Opus 4.7, operating without human assistance, was about 20 times faster than the fastest human team at all tasks completed by participants less than a year ago.
