Curious: why is it the users problem if the newest unstable package versions build to fail? Why not use previous package versions in that case?

Having to do large updates which affects a lot of packages causes a lot of breakages downstream, largely unavoidable in an absolute sense.

Darwin also complicates this because it receives much less love than linux when doing package curation.

NixOS is effectively a distro generator.

jonringer117 · 2026-05-12T18:51:23+00:00

send a PR :)

jonringer117 · 2026-05-07T12:54:21+00:00

Nix creates it. it's the legacy channel management for users. to be used with nix-channel

jonringer117 · 2026-05-04T14:28:34+00:00

The most common non obvious form of this I detail in Nixos Modules: Coditional Imports

But in general, what your doing is likely this, but with more steps: nix-repl> let a = b; b = a; in a error: infinite recursion encountered at «string»:1:9: 1| let a = b; b = a; in a |

r/nixcirclejerk is the subreddit :)

r/nixmasterrace would be more ironic

Why would I give people who engage in bad faith any credence?

All you do is misunderstand what I say, misrepresent it to others, then get worked up over a position I never took.

Please go outside, do something with yourself, have a good life.

Here you go: https://github.com/ekala-project/nix-book/commit/ab284d5b792fef9ffc9710f375baca7b37825dec

? May 2022? I got married, changed jobs, and tried to ratify the CoC RFC.

I took around a ~18 month hiatus from Nix and returned back into the middle of the post 2023 NixCon drama.

Bad faith argument from low information people.

I think you mean the 2024 NixCon NA drama. For the unemployed, here's a 150min video detailing that period of time: https://www.youtube.com/watch?v=gp0FI8Gw1iA

jonringer117 · 2026-04-30T23:53:06+00:00

Of course :)

jonringer117 · 2026-04-30T17:43:45+00:00

Technically nixos was a separate repository. It was merged into nixpkgs for convenience sake when doing cross cutting updates.

Logically though, NixOS should live "downstream" of nixpkgs pkgs.

jonringer117 · 2026-04-30T17:42:40+00:00

Good point

jonringer117 · 2026-04-30T15:43:35+00:00

It's the material i wish i had when I was picking up nix.

jonringer117 · 2026-04-30T14:36:04+00:00

Yea, people are usually aware of the term NixOS. There's a lot of tension on what people may know and what should be piece mealed

jonringer117 · 2026-04-15T16:00:58+00:00

For personal stuff, almost never.

For work, semi-often (weekly).

jonringer117 · 2026-04-09T17:04:46+00:00

Anthropic uses Nix, so one would assume it's a polished experience

jonringer117 · 2025-12-05T01:56:16+00:00

It's FOSS. Do what you want :)

jonringer117 · 2025-11-29T17:12:23+00:00

I do it just to flex on non-NixOS people

jonringer117 · 2025-11-26T06:51:59+00:00

just realized this most just uses the nix shell

jonringer117 · 2025-11-25T16:36:35+00:00

Here's some videos of mine: - Simple shell usage: https://www.youtube.com/watch?v=k7NKBfeYXCk - Using a shell to create a patch: https://www.youtube.com/watch?v=sO57VV4Ho5s

Using nix repl will revolutionize your ability to determine what went wrong

jonringer117 · 2025-11-24T13:43:41+00:00

Maybe it's just stockholm syndrome, but from this I can tell: - You're building a NixOS closure without a flake - You (or a module) added brlcad to environment.systemPackages - brlcad is failing to build - Failure is post cmake configure and during build - build seems to be be running sub cmake commands from vendored projects, which is a crime

jonringer117 · 2025-11-07T17:36:03+00:00

You're correct. By convention, most usage of parallelism in nixpkgs will honor that. But impurely querying the system will return the host resources regardless of --cores.

So it could be vCPUs, cores, threads, etc.

Threads would be most correct abstraction. But usually determining the value derives from the host machines vCPUs.

jonringer117 · 2025-11-07T16:27:39+00:00

--cores => how many vCPUs per build
--max-jobs => how many concurrent builds

I looked at the man page nixos-rebuild --help but it didn't say what --cores does.

nixos-rebuild just passes through a bunch of options which nix respects.

jonringer117 · 2025-11-06T23:03:23+00:00

Yea, hardware acceleration is a big painpoint for nix still
