Had a lot of headaches the last week or two trying to optimize star citizen as well as fix a vulkan RHI bug which was affecting unreal engine games.

Apparently rolling release schedules (like NixOS23.05, 23.11, 24.05...) are better for servers since they're less prone to change, where as nightlies like for the unstable Branch are better for gaming since those latest drivers are likely the current ones for a newly released game

I want to start a new project, and I want to try to handle all the reproducibility / "containerization" in nix instead of dockerfiles. I see some examples online but I think they're including more uncommon procedures and/or don't do things the "nix" way.

What's the right way to manage a simple python project? Should I just make a derivation.nix for use in nix-shell -p and have the ephemeral shell be my container? Can/should I do it with nix flakes instead? What would a simple nix flake look like that:

pulls an initial python repo from github

possibly executes whatever build instructions might be included

extends other system packages or other versions of the same python package,

has local area network access,

and GPU access

I see you can delete everything older than some period of time, but what if I want some older than a year? Or should it be interpreted that: whatever build configuration was used, it is tested thoroughly at that point, and it would be better to rebuild from a nix configuration stored on git?

Edit: my issues came from copying source .nix configurations for the pig manager, not configurations that I would include on my computer. Finding how to include what where was much easier with search.nixos.org

Hi, I've finally cleansed my system of windows and switched fully into nix. I want to learn this OS the right way, but have ran into some noob troubles. Any help would be greatly appreciated. Ideally, these changes are things I would include in my configuration.nix

• How to install electrum wallet on nixos? I found this default.nix for electrum and thought it would be as easy as nix-build default.nix but was mistaken. It says " cannot evaluate a function that has an argument without a value ('fetchurl') Nix attempted to evaluate a function as a top level expression" but on a later line that value is inputted to the function (if I understand right)

src = fetchurl { url = "https://download.electrum.org/${version}/Electrum-${version}.tar.gz"; sha256 = "sha256-BxxC1xVKToUjgBo4mEeK9Tdhbd/+doHcTTJsXDtaELg="; };

• How to install KVantum Theme Manager? I was following this guide and tried to add gcc/g++ and the x11 package dependencies but I get undefined variables for the x11 libraries. Some recommend using stdenv.mkDerivations but I haven't used that much nix before so I'm not certain if I should be going down that rabbit hole

I'll start: I (wrongly) used the card mom said was for emergencies for the original Kickstarter. Since then I've gotten a degree, started my career, partnered in a startup, and moved down and across the country a couple times as well.

Seems like all the scaling upgrades mentioned in the previous roadmap are about done (segwit, lightning network, taproot, schnorr signatures...)

I guess drivechain would be nice to see, but I haven't heard of any updates on that project in a while. Are there any other plans to look forward to?
