The article talks about how APT10 is elusive and actually insults the people who try to study it. 

This article discusses users and groups in linux and also access control lists. It walks through using the terminal to create users and groups, add users to groups, and even creating files and adding content to them. Then it breaks down the permission settings. I find this article helpful because it lists commands for every step you would need from creating users, groups and files, to setting the permissions all through the CLI.

This article is a great refresher of the TCP/IP model and gives beginner sysadmin tips and tricks for troubleshooting Linux environments. The article lists sequential commands at each layer of the model as well as describing common issues an admin might deal with.
