Migrating From MySQL 5.7 to MariaDB 10.2 on Ubuntu 16.04
For those unfamiliar with MariaDB, it’s a fork of MySQL that is dedicated to remaining free to use. It was created the day Oracle bought out Sun Microsystems in 2010 who had previously acquired MySQL in 2008.

Awesome Linux Command-Line Tools – Network Edition
Here’s a list of Network tools for the Linux admin whose only resources are a keyboard, a terminal and whatever brains they can muster. No GUI’s here people. These are all tools I’ve found invaluable or at the very least, super cool to play with. Who hasn’t watched movies like The Net or Live Free or Die Hard and thought, “That’s awesome.
