I'm a Linux user. I started using Ubuntu in 2006 and havn't looked back. Currently (2016) I'm running the Long Term Support (LTS) version of xUbuntu (xfce) and UbuntuServer.
I'm currently using Ubuntu for web development, this article explains how I configure Ubuntu for either desktop or virtual machine development. I also talk about Ubuntu Server on Virtual Private Servers (VPS). By using Ubuntu on both the desktop and Server you can easily match development and production environments and avoid the use of extra tools such as vmware, virtualbox or docker.
Have you forgotten your MySQL root password? I must admit I've been guilty of this a few times. Also helpful if you are working on a project where the previous developer or server admin has vanished. This article tells you how to reset your password.
