The gauntlet was thrown down at 5pm on a Friday and by 2am Friday night we had our first contender. I arrived home to see the code and decided to throw my hat into the ring. I had made some attempts at c plugins…

Why Tarsnap doesn't use Glacier
On the surface, Tarsnap sounds like the perfect use case for Glacier. Out of every TB of data stored on Tarsnap, in any given month approximately 100 GB of data will be deleted, while only 33 GB of data will be downloaded; in other words, Tarsnap is very much a "write once, read maybe " storage system. Tarsnap's…

The Laser Doodler
So I’ve got a project coming up (that may have something to do with this tweet ) that will require a few LED matrix displays. I found a suitable candidate online and ordered one to play around with.

But if you keep exercising… well, it just keeps getting more painful. When you’re done, if you’ve really pushed yourself, you…

Another go at the Next Big Language
2007 was a different time for languages. While Java held the popular crown, the mainstream programming community were still coming to terms with Java 6. Released 3 months earlier, it was very much an evolution of the Java 5 watershed. Its arrival heralded the end of life for Java 1.4 and represented an opportunity to…

Why you should continue working on your bad idea
"The brick walls are there for a reason. The brick walls are not there to keep us out; the brick walls are there to give us a chance to show how badly we want something. The brick walls are there to stop the people who don’t want it badly enough. They are there to stop the other people!" - Randy Pausch
