The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare [email protected]:usi-systems/easytrace.git

This guide has moved to a GitHub repository to enable collaboration and community input via pull-requests.

Borg Backup Script

This is a little helper script to regulary back up your data using the Borg backup tool. I wrote this as I was frustrated with Deja-Dup, which does not allow me to exclude directories by pattern, hence I ended up with backups that were very large and took a really long time to create because they contained many directories with non-essential files (e.g. node modules or Python virtual environments). Borg backup is a simple tool that offers everything that Deja-Dup does and is easier to customize.

Put the script in your home folder and make it executable.
Call it regularly using e.g. cron (put e.g. "0 * * * * [your username] /home/[your username]/make_backup.sh" in your /etc/crontab - this will call the script every hour). Please note that the script will perform its own checking to see

Deploy K3s and Rancher on Raspberry Pi 4 cluster

Today I tried to setup a small Kubernetes cluster on top of 3 Raspberry Pi 4 (4GB Memory). Here is the steps to install the cluster.

Preparation

I have 3 Raspberry Pi 4 stacked with PoE headers and connected to a PoE switch at home. The are connected to Internet through a home router. All Pis are equipped with a 64GB Samsung SDXC card flushed with Ubuntu 20.04 image.
