Sad to hear that. I still remember applying for setting up my open source project on Sourceforge. My project eventually had 160.000 downloads from Sourceforge. Back in the days Sourceforge was immensely helpful for managing and distributing open source software.
It still is! I use it instead of github for some projects.
I was a regular on PHPBuilder.com back in '99 when I was a rookie programmer; Tim answered more than a few questions for me and was always a supportive and encouraging guy. Very sad to hear this news.
Does anyone know how he died? Can't seem to find anything about it.
