This is how I set up my headless home server with a Jupyter Lab Docker container with an Nvidia GPU runtime. Login is handled by a GitHub OAuth application. Nvidia drivers and the container runtime First, check here (replacing the CUDA version in the URL with your own) to see which Nvidia drivers you need for the CUDA toolkit version you want. I’m using CUDA 11.4.2, which means I need at least driver version 470.

This guide shows how to host multiple Minecraft servers on a single machine with docker-compose. mkdir minecraft_server cd minecraft_server mkdir data/ wget https://kylrth.com/post/minecraft/docker-compose.yml \ -O docker-compose.yml This docker-compose setup uses itzg’s Docker image, which you see further documentation for here. If you’re moving from a vanilla Minecraft world, do the following to get the different world directories in the right position: cp -r ${OLD}/world data/server/world mkdir data/server/world_{nether,the_end} mv data/server/world/DIM-1 data/server/world_nether/DIM-1 mv data/server/world/DIM1 data/server/world_the_end/DIM1 Here’s the map from vanilla Minecraft directories to Spigot directories (which is what itzg’s container uses):

This is how I set up my own Matrix server on a Raspberry Pi with Docker. Unfortunately, the Matrix community has stopped releasing ARM images, so the latest version that will work on ARM is v1.26.0. These instructions will work the same for x86_64 systems, except you’ll be able to use the default x86_64 images in the docker-compose file. This installation comes with Maubot and matrix-registration containers too. If you don’t want to use those features, leave out those sections of the docker-compose config and don’t follow the instructions in the corresponding sections.

LaTeX has a ton of different flavors, releases, and installations: MacTeX, MiKTeX, TeXworks, XeTeX, pdfTeX, LuaTeX… If you’re using Linux and just want to edit LaTeX files in Visual Studio Code and have them automatically rendered as PDFs, follow these instructions: On Arch-based distros, install the packages listed here. On Debian-based systems, sudo apt install texlive. Install some Perl dependencies: sudo cpan Log::Log4perl Log::LogDispatch Log::Dispatch::File YAML::Tiny File::HomeDir If you want to use FontAwesome on Arch-based systems, install the oft-font-awesome package and then do the following (source):

GPG is cool. You can use GPG to send encrypted messages, sign files to prove you generated them, and sign git commits to prove you committed them. You can get my key here. DigitalOcean has a neat guide to getting started with GPG. It explains asymmetric encryption, key generation and revocation, and key signing and maintenance. Git commit authorship can be modified by anyone, as demonstrated by this tool. But by uploading your GPG public key to GitHub, you allow anyone who trusts GitHub to be sure that commits marked “verified” were actually created by you.
