Hello, I have been a professional hairpuller aka programmer for a large company during the last nine years. The acquiring company is closing down the california office so I'll be out of work at the end of June at the latest. I program in a variety of laguages, C#, C++, C, Visual Basic, SQl Server among others. I live north of Sacramento in Paradise CA. I've been programming since the early 1980 and people accuse me of going bald. I'm not going bald, my hair is just migrating south and into my ears.
I am a firm believer that the most widely used programming language is #$@$@$%#$%^ but folks tend to object to the unusual synatax where each word has a colorful meaning and sentences are limited to three words max, while the punching bag flys back and forth so fast it heats up from friction like a meteorite through the air.
In short, I'm nuts, but I'm good at what I do.
Programming is like beating my head against a brick wall, it hurts so bad I can't stand it, but when I stop beating my head against the wall (Solve the problem), it feels so good I gotta do it again!
