Robot Costume Contest

Hey guys!

If anyone is interested (and has mad costume-making skills), ezrobot is running a costume competition for Halloween! It can be any robot, it does not have to be an ezrobot. :) You can win some credit, and we would love to see some submissions from Let's Make Robots!

Quality of Life

I'm on a crusade. A crusade for better quality of life. In fact, a crusade for quality that means life. A lot of money is wasted. People are being injured, sometimes seriously, or even being killed because of poor quality software. We have the power to help put an end to it. If you have read any of my previous posts, you may have noticed a recurring theme: software quality. Even if the post wasn't about that at all, it seemed to always crop up. And that is what my crusade is about. I need your help.
