I also have happened across some very cool tools.
I have worked on a few small projects on my own, although my family, church, and full time job keep me busy.
NetSnagger – a simple internet bookmark utility, developed in C++ using my own C++ GUI framework.
RmoreUrl – a Java Based simple utility with which a UNIX client (for example emacs running VM, an email client) can send a URL to a MacOS box which can them be opened in a browser.
Most of my profession carrer has been spent in UNIX based C++, C, Java, and Lisp development, web development, and a significant portion also being Windows. Check out my career for more info.
