Load “Twitter” ,8 ,1
I’m not sure why he did it, but someone has created a Twitter client for my favorite personal computer of all time, the Commodore 64. In the video below, you will see a C-128D running in C64 emulation mode. When I see people do things like this, I feel happy inside. No, Twitter is not [...]
Better Productivity With Xen, Ubuntu and XDMCP
Being over-loaded with work is a vicious cycle, especially when the work involves more maintenance than creativity. The cycle goes something like this: 15 things require immediate attention You give immediate attention to 15 things at once Despite the cycle of #1 and #2, #1 still persists at the end of the day Even if [...]
Why I reverse arguments

Explaining race conditions
It can sometimes be difficult to explain abstract concepts to people who don’t have programming backgrounds. I was working on a really simple single system image cluster for someone, all that we had left to complete was the cluster announce mechanism and heartbeat configuration. The design called for a completely automated / self-recovering setup. Even [...]
What is a computer, really?
I received a very interesting e-mail from the FSF today, sent via its announcement mailing list. The FSF (and numerous others) are very concerned about the IPhone being out of reach of free software due to its locking restrictions and the Apple developer NDA. I began to wonder, in this day and age, what is [...]
