Rooting and installing Gapps on Coby 1042 tablet from Linux/OSX
Vacation time is great! I went into Fry’s today and found they have the Coby 1042 (10.1″, Android 4.0.3) on sale. Normally I don’t pay much attention to the lower end tablets because they miss one or more features I think are pretty critical in a tablet: Capacitive display Fast CPUs SD card slots Ice…

So you want to be a Systems Administrator?
Recently I wrote about the shortage of entry level Operations people. These are the people who run the millions of computers that make everything in our daily lives possible.

Run commands against all of your Puppet or Chef hosts
