Avatarify is a cool project that lets you create a relatively realistic avatar that you can use during video meetings. It works by creating a fake video input device and passing your video input through a neural network in PyTorch. My laptop doesn’t have a GPU, so I used the server/client setup. setting up the server permalink Be sure you’ve installed the Nvidia Docker runtime so that the Docker container can use the GPU. You can see how I did that here. Run the following on the server:

I host several services on an Alienware gaming computer I keep at my apartment. (We call it the spaceship.) I originally got the computer so I could have a computer with a GPU for machine learning projects, but I’ve since started using this computer to host a bunch of different services. Here I’ve documented how I set up the server. operating system permalink To keep things simple I use Ubuntu 20.04 LTS. Here’s a speedy way I’ve found to write installer ISOs to USB drives for installation:

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 permalink 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.You can use sudo apt purge nvidia-* to cleanly remove older drivers (or broken installs) before installing the desired version.

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 /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 with Docker.These instructions were originally for ARM, back when I ran this server on a Raspberry Pi. Unfortunately, the Matrix community stopped releasing ARM images, so the latest version that will work on ARM without QEMU is v1.26.0, which is very old now. These instructions have been updated to use amd64 images, but I’ll preserve the references to ARM images as comments. If you’re going to work from a Pi, be sure to switch it to run in 64-bit mode for optimal performance: echo 'arm_64bit=1' | sudo tee -a /boot/config.txt && sudo systemctl reboot. There is an Ansible playbook that’s quite popular, but I host a lot of other services with Docker on the same server and I wanted to continue managing all of them together, just with docker-compose.
