A curated list of command-line utilities written in Rust

Note: I have moved this list to a proper repository. I'll leave this gist up, but it won't be updated. To submit an idea, open a PR on the repo.

Note that I have not tried all of these personally, and cannot and do not vouch for all of the tools listed here. In most cases, the descriptions here are copied directly from their code repos. Some may have been abandoned. Investigate before installing/using.

The ones I use regularly include: bat, dust, fd, fend, hyperfine, miniserve, ripgrep, just, cargo-audit and cargo-wipe.

This is a remainder for myself because I need to run Mathematica once a year. Often the version I use is different from nixpkgs.

First you find a copy of Mathematica_12.1.0_LINUX.sh or similar and find its sha256sum. Then you go to nixpkgs and copy all Mathematica files to a local directory. You need to modify default.nix and wrap its contents into

let pkgs = import <nixpkgs> {};
in pkgs.callPackage (

This is a brief guide on how to install Archlinux as a WSL2 distribution and how to set up CUDA afterwards.

As of late, Window's WSL2 offers GPU passthrough from WSL2/Linux to Windows for NVidia graphics cards which allows to run (and develop) CUDA-based applications on the WSL2/Linux-side with almost native performance. Unfortunately, the official guides for the CUDA setup for WSL2/Linux are predominantly Ubuntu-specific. Here's to you, Arch!

1. Install Archlinux

Make sure that your Windows meets the dependencies and that your WSL2 is set up. See these instructions.

Archlinux is not among the default distributions available for WSL2. We'll install it from a tarball instead, a functionality offered natively by the WSL.

» sudo systemctl daemon-reload

System has not been booted with systemd as init system (PID 1). Can't operate. Failed to connect to bus: Host is down

Edit*

Open /etc/wsl.conf with any editor:

Setup ExpressVPN in OpenVPN on OpenWrt

These instructions will get ExpressVPN up & running in OpenVPN on OpenWrt.

opkg update
opkg install -force-overwrite openvpn-openssl luci-app-openvpn

Log back into Luci & there will now be a menu VPN > OpenVPN.

	// system that was designed to be reflective so one doesn't have to resort to things
	// like Gödelian numbering systems or other schemes in order for it to reason about

	// But seeing how I know little to nothing about Tree Calculus, I figured this would be
	// an interesting way to explore it.
