Now I’m sitting on a plane, heading back to my family. I just got through with the RedHat Summit 2017 in Boston and I also visited some of my family while there. It was an intense 3-4 days. I generally love Boston, and also Cambridge across the river. While I was there, I took a visit over to the MIT Press Bookstore, and bought a few books, including Grokking algorithms which was a book that I already had on my wishlist, but wasn’t one I could find in the store anywhere else.

I recently started with a new company doing more of the role I was in at my previous job focused on J2EE applications, etc. However, I additionally ended up taking over management of Eucalyptus which is an AWS compatible cloud solution.

Intel Graphics Issues with Ubuntu 12.04

 Posted on February 20, 2014  |  2 minutes  |  244 words  |  David Mitchell

I have an XPS 13 Developer edition laptop (aka Project Sputnick), after some updates to Ubuntu in recent months, it would randomly freeze. It became apparent it was the graphics card that was freezing as processes were still running even though the display image was frozen and the mouse nor any other input seemed to have no affect (if I left it on downloads would finish). This was very frustrating as I had bought an officially supported set of hardware for Ubuntu from Dell to eliminate these kind of hardware support headaches. [Read More]
