Jitsi Meet install on a Raspberry Pi 4 with Ubuntu Server 21.04

This guide helps you host your own Jitsi server on a Raspberry Pi 4B. It is adapted from Jitsi's quick install guide and the Jitsi on ARM guide written by crouchingtigerhiddenadam. The biggest difference is this is designed to work with a Pi running Ubuntu Server 21.04 instead of Raspbian.

I did this because I'd rather set up Jitsi Meet on a Raspberry Pi I already own than add a dedicated VPS (and pay AWS's bandwidth costs) just for that. I used Ubuntu 21.04 because I'm more familiar with Ubuntu than with Raspbian, and using an arm64 OS makes the setup easier than on armhf. I also tried to use distribution packages instead of manually downloading individual deb files throughout.

This guide assumes you already have a DNS name set up with an A record pointing

This was supposed to be posted on the SC forums at scsynth.org, but I ran into the spam filter and thus saved it as a Gist first. It's on the forums now: My attempt to build SuperCollider on Termux/Android

I've been thinking about using SuperCollider on my phone. There's glastonbridge/SuperCollider-Android which hasn't been touched since 2014, so I thought I'll try to build a current version from source, based on the guide for Linux. Also, since Termux provides a great Linux CLI environment, including build toolchains, directly on the device, I wanted to try building SC under Termux.

Spoiler alert: I didn't manage to do it. The main problem is not having an audio driver, since the Linux build requires libjack, and neither Android nor Termux provide it. (Termux has

Open the example golang notebook and make a copy of it. Then, run the first cell to install golang, gophernotes. Then refresh and skip the first cell to test golang in later cells.

Below are the steps required to flash a NextThingCo CHIP or PocketCHIP from the command line, as of November 2018. The web flasher no longer works, and there are numerous errors when flashing from the command line, mostly due to broken dependencies. The following method works for flashing a CHIP as of November 2018:

Note: Flashing must be done on Linux. Tested on Ubuntu and Rasparian. Mac OS seems to not work.
