Full-stack HFT systems developer. From mechanical sympathy and cache-optimal data structures to deep neural networks with super-human performance. One-man army.

@charliermarsh The Benchmark methodology of the chart you refer to, with 2 (two) runs of the complete benchmark suite using the default process scheduler and priorities on random CPU cores cannot possibly produce any statistically meaningful results, I am afraid.

A 0.2% speedup of python-build-standalone over Debian Forky’s Python is almost certainly within measurement noise.

Plot the raw measurements with error bars. That makes it obvious whether differences between builds are real or just run-to-run variation.

Typical Python benchmarking noise is 1–3%, depending on how carefully the suite is run. Differences below about 3% are usually not statistically meaningful.

Enabling the compute-heavy THP settings improves the run-time by 5-45% relative to Linux default THP settings.

@norpadon Teenagers hacked what's left of Google Page Rank by spamming «Veteran Rust developer» in every title to dominate searches this year.

It sounds ludicrous in this decade, I agree, but I guess they didn't expect Rust to persist for so long, on the other hand 🤷😂

@KevinMilczewski @ChShersh A store invalidates all copies in L1d caches of all other CPUs. And copies in all other L2 and L3 caches, if any.

Hot paths normally cannot afford the extra latencies of cross-thread communications.

@CallMeOuta @TheGracia_here You love C because you get paid for time.

Were you paid for results, you'd know and love C++ more than its C subset 😁

@ChShersh Always question any unsolicited advice given free of charge -- someone else pays to plant their message into your mind.

@Toth_Bentheum @TheProjectUnity Geopolymer concrete is unrelated to your flat Earth beliefs, I am afraid.

[max0x7ba @max0x7ba]

@ChShersh Can you write Rust DSL in C++?

[max0x7ba @max0x7ba]

@Toth_Bentheum @TheProjectUnity The scoop marks were made in the geo-polimer concrete when it was still wet. The megaliths are built with geo-polymer concrete cast in place. No moving of heavy stones was ever involved.

@Denis631396 @USKnightTemplar @d3athtotheidf @clashreport You are so malinformed it is not even funny, rofl.

Ukraine built cruise missiles, strategic nuclear missiles and icbms for USSR.

Ukraine provided the launch functionality of its nukes to Moscow.

[max0x7ba @max0x7ba]

@USKnightTemplar @d3athtotheidf @clashreport I did donate to Ukraine from my personal bank account, if that's something you'd like to know.

Your barrage of irrelevant questions followed by inept cold reads and awkward projections only demonstrates your ignorance and arrogance, I am afraid.

[max0x7ba @max0x7ba]

Just reconnect with your body, try different code editors and notice which one gives you the hardest boner.

No 3rd-party 2nd-hand opinions can possibly match your own direct 1st-hand experiences delivering the most profound and deeply personal insights.

Not paying attention through one's own senses disengages from the primary mode in which every creature since the origin of life has connected to its environment.

Well, the US manhattan project scientists brainwashed by USSR propaganda into thinking that communism was the greatest idea ever, leaked the atomic weapons secrets to USSR in order to support and bolster communism.

Putin threatening the world with atomic weapons today is the result of US manhattan project scientists leaking the atomic weapons secrets to USSR.

Yet, giving a few rusty M1 tanks and F-16s to Ukraine with discontinued and expiring weapons is Zelensky taking advantage of US; while multiple orders of magnitude larger waste, fraud and corruption uncovered by DOGE is fine and dandy.
