"I was recently tasked to fix some 508 compliance issues in a C#, ASP.NET application at the company I work for," writes Dan Johnson, "I was warned that the code may be a little, let's say, not well matured. That's fine, I've seen bad. Architecture, style and good practices problems all aside, I began to see comments throughout the code like this:"

//don't do this -- too slow when there are many rows in the grid
//return;
//update:  actually it's pretty fast now - use it if desired and 
//don't rebuild the grid on the client because using setTargetURL DOES NOT WORK
//go ahead and do it - we're not using links for the app names now

"I work at a medium large IT company with a handful of developers. A few months ago one of my colleagues left. He was a developer-slash-designer and was the only on in the company who used a Mac computer (a disused old Mac Mini)," writes Jan V., "His design skills were significantly better than his developing talents. Not that he was a bad developer, but he always had a ... let's say ... his own perspective on things, including his way of setting a debug flag."
