I got shock in a train close to Lille in France because of a power failure on my way from London to Paris last week-end. From, 19H30 to 5h20, I didn't have much to do but a great MacBook Pro 13” with a great batterie life. I started writing this article about OpenGL and the good reasons to be optimistic these days being a OpenGL developer!
For the story, the train runs out of power a lot sooner than my laptop!
Enjoy!
