Nix wrote half of my debugger
A few days ago I wrote about Rewind VM, a deterministic VM where every run of a Nix build is a pure function of its inputs, thread schedule included! I have been using it to find, reproduce and solve numerous race conditions in Nix builds, but it’s been making me feel a little crazy. What is this superpower, and why…

We scaled PgBouncer to 4x throughput
PgBouncer is single-threaded, so a single process caps out at one CPU core no matter the box size. See how ClickHouse Managed Postgres runs a peered fleet of PgBouncer processes with so_reuseport to scale pooling across every core — with benchmarks showin

Team from ETH Zurich make high quality quantum swap gate using a geometric phase
Researchers at ETH Zurich have realised particularly stable quantum logical operations with qubits made of neutral atoms. Since these operations, called quantum gates, are based on geometric phases they are extremely robust against experimental noise and can be used in quantum computers in the future.

I stopped working on the reverse-engineered Apple Neural Engine (ANE) driver three years ago, upon a sad mini realization that the ANE block is just not that useful, and I could be doing more useful things, and moved onto upstreaming other, more useful, blocks. The ANE's architecture was too opinionated to build a…

Meta Horizon Worlds on Meta Quest is being discontinued
Earlier this year, we shared an update on our renewed focus for VR and Horizon. We are separating the two platforms so each can grow with greater focus, and the Horizon Worlds platform will become a mobile-only experience. This separation will extend across our ecosystem, including our mobile app. T...

The most official water costs $120k a gallon
We all learned in science class that water freezes at 0 °C or 32 °F at atmospheric pressure. But what water, exactly? Even after you distill out all the dissolved salts and minerals to get pure H2O…

RE#: how we built the fastest regex engine in F#
around a year ago, we built a regex engine in F# that not only outperformed the ones in dotnet, but went above and beyond competing with every other industrial regex engine on a large set of industry-standard benchmarks. it also supports the full set of boolean operators (union, intersection, complement) and even a…
