I found the tools weak at best, confusing and overcomplicated at worst. The code from OneLogin [1] was the clearest example I found, but it leaves various things as an exercise for the reader, such as obtaining the relevant public key and

I deploy a couple things via Nix package manger to non-NixOS systems, and I manage my own system configs, etc. within Nix. My "external configuration management system" is pared down to a small script that symlinks everything in a

Execline is a little mindbending at first, but a really nice way to write scripts for launching other programs.

I would probably make the same decision, but I hope in the end Caro is easy to wrap with Nix, which is a breath of fresh air particularly when needing to mix dependencies that cross language boundaries and share those build recipes with a t

I've not used Guix, but looking at those slides, the ability to take the build definition of the "hello" program, inherit everything but change the version, looks very interesting. I'm not aware of a way to do that in Ni

The struct is currently storing a pointer to the mutex (which was allocated with malloc). The call to pthread_mutex_destroy does not free that memory. Valgrind is your friend :) http://valgrind.org/docs/manual/qu

Well, if the compiler will also report error for recursive calls not in tail position... There are strategies to prove various things about recursive calls. See Ada/Spark's explanation for Rule 17.2 in [1]. I'm not familiar w

I don't really disagree with your points, but "the best solution we've found given those constraints" include a lot of pain. Something like Nix comes with a lot of different pain, but I suspect many pain points could be

I've actually been exploring nix myself recently. It has some interesting features. I'm finding it quite nice to maintain some C-based packages across both Linux and Mac OS X (where it is somewhat of a competitor to Homebrew). I&#

Nice, but can anything challenge the "every language gets its own unique package manager"? (And own unique build system for that matter).

I found the nix expression language somewhat confusing at first, but I was able to create simple packages after a couple days. You can find many examples in nixpkgs, e.g. https://github.com/NixOS/nixpkgs/blob/
