Linux from the command line | Linux for sysadmins -- Reading compressed text files
While this is a convenient tool for people that save space by compressing their ordinary text files, it's a really handy tool for system administrators that want to view old log files...assuming you have your system setup to still store them this way and haven't given in to systemd's log storage nonsense.

Linux tips & tricks | Linux for sysadmins -- IPFire, a user friendly Linux firewall
Linux tips & tricks | Linux for sysadmins -- IPFire, a user friendly Linux firewall
For advanced home LAN users, small businesses, and charity organizations a great way to build an inexpensive but powerful firewall is to throw two network cards in an old PC and installing Linux.
If you don't have advanced Linux firewall/networking skills yet, there are a few ways to make it work. Pfsense is one way. This looks like another one.
I've never used it myself, but I thought it was worth sharing.
One thing I find interesting about it is that it's a purpose built, from scratch system. Not a general purpose distro like Fedora or Ubuntu hacked up and modified for firewall duty. It also seems to have a pretty decent administration system and firewall management interface.

Linux for sysadmins -- Managing virtual machines with Vagrant
This is a system to help manage virtual machines and it looks like it might be helpful for some regular VM users. However, be sure to read the docs for your Linux distribution because some, especially ones that are for Enterprise use come with built in or integrated tools to perform these functions.
