  • Month-long Linux Upskill Challenge

I just came across this:

http://linuxupskillchallenge.com/

It's a (free) month-long course to advance your Linux administration skills.

I am still discovering it. Next month's course starts on July 6th, but I guess I could just read through the material from the previous months.

Have a look on the link above if interested.
That sounds like something I may be interested in. Thank you for sharing.
