What our readers say

Very useful in getting started with Go. This site has the potential to be what Baeldung is for Spring!

Thanks for the helpful articles about apt. I'm an experienced Unix/Linux admin but rarely have to install or modify packages, so I can never remember the proper commands.

Thank you for your article "2 easy methods to extend/shrink resize primary partition in Linux".

Thanks for the tutorial. It helped me to automatically mount an external USB triggered by a Borg backup command.

Got XFCE4 running through XRDP thanks to you. And I can stop staying awake till 2-3 AM.

Nice explanation of OpenSSL Certificate Management. Helped a lot.

Instructions are very clear, helped us out for an issue we had.

I've read your article on Goroutines, and it helped me a lot. It was exactly the right chunk to understand it without wasting time. Thanks.

10 simple ways to sort a dictionary by key in Python on GoLinuxCloud is a really excellent tutorial.

Thanks a lot for your efforts. You saved me tons of time. Your explanations are awesome. I wish I had read such articles quite a few years ago. :)

Extensive coverage of complicated subjects. I've been living here for a week.

Thank you for the "How to update GRUB2 using grub2-editenv and grubby in RHEL 8 Linux" page. Great clear instructions that worked.

The OpenSSL Certificate Manager information was very helpful when I was setting up a certificate for my lab.

A beautifully concise and complete tutorial on how to renew a self-signed certificate, including how to verify each step. Nicely done!

Many great tutorials, pleasant navigation... I'm going to make GoLinuxCloud my home page. Thanks so much for the job!

Thanks for your work. It's definitely one of the better spots to learn something for free.

Hey mate, thanks for your tips and tricks. You obviously know your stuff. Legendary effort.
