Write a Nix expression to compile your document. That way you can be sure it keeps working. I did this long ago for my PhD thesis and other papers.

The problem with using decibels is that since it is a relative unit you need to know what it is relative to, and that is often not just the unit but also the quantity. Unfortunatel…

NixOS system configuration is centralised and documented.

The speed of sound is the square root of a modulus over the density where the modulus for a gas is the bulk modulus. The funny thing with vibrations is that it is not the density t…

To improve the COP you need a gas with a high ratio of specific heats and low Prandtl numbers. The Prandtl number is the ratio of viscosity to thermal diffusivity. Helium works fai…

Ha, familiar. I decided I wanted the pdf of my dissertation to be reproducible and hence packaged it with Nix.

This is indeed not very good. Note there is a reason that overridePythonAttrs exists: it overrides the call to buildPythonPackage instead of mkDerivation. There is/was an RFC on st…

It should be noted this was achieved by removing Python bytecode from the builds. This has a performance hit and should probably be reverted.

Exactly. Python maintainer of Nixpkgs here. What we need is to be able to use a resolver such as included by pip or poetry, to build up our package set. In Nixpkgs this is nowadays…

Done! https://github.com/disruptek/nimph/issues/138

Thanks! I was only aware of Nimble. I'll have a look at it. One thing I noticed right away that it seems to be lacking (judging from the `nimph.json` assuming that is the lock file…

For a while now I've been looking at using Nim, and this weekend I did my first project with it: a tool for creating binary wrappers. In Nixpkgs we often create wrappers, but those…

The release announcement on Discourse: https://discourse.nixos.org/t/nixos-19-09-release/4306

Nixpkgs supports multiple versions of Perl and allows you to use them side-by-side.

Yet another format for self-contained executables, and one that looks pretty similar to the already existing AppImage. Note that Nix users can use `nix-bundle` to create AppImages …
