Finding bugs ...

Looks as if I have a talent for finding software bugs, especially in other people's software. I find bugs in mine, and I fix them. Other people's software I just have to report it and wait until those who know that particular implementation inside out can fix it. In the past year I've found a bug in Sun Microsystems GlassFish application server. The server was stable, it just didn't do what the specification said it should. The bug was rather esoteric and had to do with default values when both annotations as well as deployment descriptors are used to configure multiple instances of an enterprise bean class. When we reported that bug it turns out our team at work were the first developers who came across that particular error. Today I just happened to come across an error that causes a segmentation fault in an Apache webserver child process. Still not sure if the error is caused by a misconfiguration or if it is a intrinsic error that must be corrected in the source code. We'll have to see later, right now I need sleep
