Ragnar {Groot Koerkamp} 🦋 Thanks! Yeah, those are just SVGs, generated with an LLM and slightly modified. Yes, SW prefetching definitely helps. Here's a quick experiment I whipped up (note this isn't the Haswell system HighLoad is running on, so the optimal stride is different here).

Andreas Kling Kushashwa Ravi Shrimali I really like Eugene Braunwald's concept of Triple Threat physician: someone who balances practice, research and teaching. I think it translates to virtually every field and have personally found it very fruitful to try to balance all three.

yarchive.net/comp/linux/cmo… Linus Torvalds illustrating how bad cmov is by comparing it to a perfectly predictable branch. How has no-one called him out for that?

"When you build a thing, you cannot merely build that thing in isolation. You must repair the world around it, and within it, so that the larger world becomes more coherent and more whole; and the thing takes its place in the web of nature as you make it."

TIL: Carriage return (\r) = instant in-place status line updates. print!("\rProcessed {} messages", message_count); No fancy TUI needed.

Can't believe I got stuck on this today: "rsync -a foo/ root@remote:/root/" will sync foo's local permissions to /root, possibly disabling ssh pubkey auth (sshd: "Authentication refused: bad ownership or modes for directory /root:") and locking you out of the server.

Supposedly on the threshold of creating a silicon deity, yet connecting to my hotspot still regularly impossible. As tylercowen said: intelligence is overrated.

Wrote a comprehensive article for Codrops on how I achieved high-performance and visually appealing fluid simulations in browsers! Hope you enjoy it :) tympanus.net/codrops/2025/0…

Here's a fun little problem: Given a u64 mask, find the max of (#1 bits - #0 bits) over all 65 suffixes of the mask. Currently I go byte-by-byte with a lookup table, but it's ugly and slow. Bonus points if it works in SIMD as well.
