@getchoo:matrix.orggetchoo hey Mic92: just came across your comment on the detnix installer thread. i'm not super familiar with the codebase just yet, but i have a good bit of experience with gha and ci janitor work, and would love to help out if i can! :) 00:16:11
@xokdvium:matrix.orgSergei Zimmerman (xokdvium)Here are some notes from our meeting with the installer team. I forgor to publish them to discourse https://pad.lassul.us/KgpbqiQpQEOX2cKF5Ehjwg#00:24:04
@xokdvium:matrix.orgSergei Zimmerman (xokdvium)Very incomplete and half-way00:24:49
@xokdvium:matrix.orgSergei Zimmerman (xokdvium)But basically it'd be great to start integrating it into our dogfooding setup https://github.com/NixOS/nix/blob/master/.github/actions/install-nix-action/action.yaml00:25:28
@xokdvium:matrix.orgSergei Zimmerman (xokdvium)PoC for 16 byte atomics on x86_64 for paralell eval: https://github.com/NixOS/nix/pull/13964. Lovers of compiler intrinsics are welcome01:07:35

@getchoo:matrix.orggetchoo thanks for the link! i'll take a closer look at some of the stuff mentioned and what's already there this weekend hopefully (new job has had me a bit busy, catching covid from it didn't help either 😆), but i definitely think i can get this dogfooding setup going. i already have a bit of experience with very similar things in other action projects 05:01:36
@jaen:matrix.orgjaen If there are other tasks that can be done in parallel for installer upstreaming I'd also be interested — I was cooking a Nix article series for $CURRENT_JOB blog (the company does a lot of Bazel, so it's structured by way of compare & contrast) and don't feel comfortable publishing them until after the installer situation is resolved, I don't really want to redirect people away from the upstream. 11:27:06
@magic_rb:matrix.redalder.orgmagic_rbAs many before me, i implemented my own very basic nix evaluator, it doesnt have any builtins right now, only does basic arithmetic. But the point of it is that it doesnt use AST walking, but rather an approach similar to the STG. Its not fully tagless unfortunately, but i think im just missing something. Anyway, it only makes sense to develop it further if its faster than nix/lix so im wondering if its possible to formulate micro benchmarks relying on a subset of the nix language which could tell me whether my impl is faster or not. Anyone has thought about this before?15:07:03
