📚 Ask Slashdot: How Can You Refresh Your Linux and Sysadmin Skills?

Slashdot reader PrimeGoat has used Linux for 20 years, "10 of which were during my career as a Linux sysadmin..." "However, there's more to being a sysadmin than just knowing how to use Linux." There are best practices that evolve, new methods of doing things and new software that constantly comes out and evolves. This is where my challenge comes. In 2012 I stopped my career as a Linux sysadmin... There's a lot of stuff that I missed out on. I'm wondering what I should do to refresh my skills and to catch up on what I've missed? An obvious solution would be to get a job as a sysadmin again, but this probably isn't going to happen, as I'm changing my trajectory. I'm currently training to become a fullstack web developer, but still have a need to update my sysadmin skills and keep them fresh... Any suggestions on what actions to take on my own to catch up and keep fresh? Leave your thoughts in the comments. What's the best way to refresh both your Linux and sysadmin skills?
