Web developers. You suck.

objectreference.net — Well, JavaScript developers, specifically. In order to aid in development of my own websites, I enabled JavaScript debugging in Internet Explorer a few weeks back.

Being a “nice” programmer

objectreference.net — Being a C# developer by trade, I naturally spend a lot of my working life programming computers.
