Missed the first lecture of our series?🫣 Do not fear! You can catch up with @EGMitchell's talk "Using spatial point process analyses to quantify the behavioural ecology behind trace fossils" on our channel: youtu.be/cW3Glw_zN0I?fe… #palaeoecology #palaeobiology #palaeontology
starlark-rust is a Starlark (simplified deterministic Python) implementation as a Rust library. We use it heavily in the Buck2 build system. Yesterday it graduated to github.com/facebook/starl…, having previously been in facebookexperimental. Nice to see our library growing up!
We just open sourced github.com/facebookincuba…. Useful if you're using the Buck2 build system and want to build a CI that only reruns the minimal subset of things that might have been changed by a PR. Essential on huge projects!
WhatsApp uses #Buck2 to build its Erlang codebase. Andreas explains how in youtu.be/E1_txkn7YKA?si…
We’ve open sourced DotSlash, a tool that makes large executables available in source control with a negligible impact on repository size, thus avoiding I/O-heavy clone operations. #opensource engineering.fb.com/2024/02/06/dev…
How did I manage to end up owning one of these? A specialist tool for producing a specific type of confusing chart, in one specific size, by hand.
#Haskell linter HLint 3.8 now out with GHC 9.8 support (thanks to @shayne_fletcher for tirelessly keeping up with GHC). github.com/ndmitchell/hli…
Just released a new Hackage release for the #Haskell search engine Hoogle - hoogle.haskell.org. I've maintained this project for 19 years, it gets 750K hits a day, but it's not had any great improvements in a while, and PRs are backing up. Anyone interested in helping?
Just released #Haskell `safe` library - has various wrappers over partial functions. E.g. tail has tailDef (return a default), tailNote (better error message), tailMay (return a Maybe). v0.3.20 adds tailErr, alias for tail that doesn't warn on GHC 9.8. hackage.haskell.org/package/safe
The GHC Haskell Compiler adding new warnings is always a pain. There's no way to suppress the warning for new without CPP or .cabal changes, which is burdensome. I like the Rust approach where the unknown suppression warning can itself be suppressed.
CircuitHub is hiring Haskellers! discourse.haskell.org/t/circuithub-i… I've collaborated with CircuitHub engineers for years on Opaleye (their database library rel8 uses Opaleye as a backend). I'm sure it's a great place for Haskellers to work.
Buck2 and OCaml work together beautifully - you need the dynamic dependencies to infer intra-library dependencies. Talk with @shayne_fletcher at OCaml workshop: youtube.com/watch?v=l4X4Bx…
Rust 1.75.0 is now available! 🦀✨ Traits now support `async fn` and `-> impl Trait` (with some limitations), the compiler got faster, `version =` in Cargo.toml is now optional, and many small functions have been stabilized! Check out the announcement: blog.rust-lang.org/2023/12/28/Rus…
We published version 6.0.0 of the fast_float library: really fast number parsing, compatible with the C++ std::from_chars standard (actually used in GCC 12+). It is a single header you can drop in your project. Brings in fast integer parsing. github.com/fastfloat/fast…
Oh, they've added a fence since @EGMitchell and I camped next to it.

Thanks for letting us Buck2 folks join in the BazelCon community day. A great series of talks.
Thanks for letting us Buck2 folks join in the BazelCon community day. A great series of talks.
Haskell's import syntax has improved a lot over the last few years. A lot of Haskell source code is formatted in the former style, with all the spaces at the front... I just think it looks so much nicer when `qualified as` comes after the module name!
I wrote about a few minor reference-counting tricks: chadaustin.me/2023/11/refere…
