So you decided that Oracle doesn’t know its left foot from the back of his neck when it comes to open source (how’s that for a mixed metaphor), but you are not ready just yet to migrate over to PostgreSQL? Consider MariaDB. Coming from Monty Widenius, the original ...

If you use Ubuntu, the full circle magazine is a great resource, go check it out. For example from the latest issue I’ve learned that I should install vim-nox on my servers if I want to upgrade ...
