Things I like to set on a new… Continue reading Some neat Vagrant tricks
A Linux development environment on Mac OS
I've been given a Macbook Pro at work. It was actually my choice, since it was the only machine with an US keyboard layout, 16 gig of ram and last but not the least, the easiest way not to use Windows and have a Unix environment at my fingertips.
