A great post with thorough replication/reanalysis/discussion and we might say debunking. Also an example of pretty decent scientific discussion. Plus deep technical dives in the comments.

На днях летел в Airbus A319 — приятно сознавать, что софт, им управляющий, был верифицирован (в разных отношениях) и собран CompCert. 😏

Когда в 2005 читал "Метро 2033" казалось, что автор установил дату ядерного апокалипсиса слишком близко... 😏

А вообще, про "Метро" вспомнил в связи с "локативным искусством" (привязанным к местности) — пока не покатался на московском метро, роман как-то не резонировал примерно никак.

Oldie but goodie. Curious highlights.
Climate models have surprisingly low error rates in terms of software bugs. It's nice that people really can and do produce high-quality software without Sales and Marketing pressure. 😏
The models systematically overestimate some parameters but underestimate others. Thus when you see graphs projecting climate into the far future, actual air temperatures are likely to be a bit lower (while deep ocean temperatures will be higher). And the see levels are likely to be higher than predicted which is not very nice.

The new(ish, compared to the previous one) (source-to-source) compiler for the Stan language is implemented in OCaml and became the default one quite some time ago. The Readme also has a reference to a discussion "OCaml vs. Rust". Mind that the discussion take place back in 2018 (4 years ago! 😱) and you can appreciate how much Rust has matured during the time.
And Stan is a huge (by impact) project in the area of Bayesian modeling, statistical analysis and inference.

Sloppy statistical analysis indeed jeopardizes lives of actual children in Africa. 😞

Attempting to prove any nontrivial theorem about your program will expose lots of bugs: The particular choice of theorem makes little difference!
LOL, so true! 😂

A guest post by Martin Kleppmann on Lawrence Paulson's blog. Martin explains the basics of distributed algorithms verification in Isabelle/HOL. As the main tools he employs (heavily parametrized) functions, maps (which are secretly functions too), inductive predicates and inductive proofs with a slightly custom induction principle (and variable generalization).

Bizarre Performance Characteristics of Alder Lake CPU
TL;DR: Some of the P-cores in Alder Lake CPU can exhibit highly unstable performance behavior, resulting in large noise for any benchmark running on it. UPDATE: A colleague of mine reported that the b
