Hobby & Open Source Projects

• Developed the turner source code hilighting package which converts C, C++, or Java source code into syntax highlighted HTML.
• Developed an in-memory logging facility, mlog, to allow post-failure diagnosis of production codes without slowing down the production code, due to file access overhead, or filling the disk with verbose log files. The mlog facility is able to keep adequate log information in only a few kilobytes of buffer memory. The buffer may be dumped to a log file on disk when an error condition is detected or examined in the core-dump if the program terminates unexpectedly.
• Developed a C-based abstract GUI library, StdGUI, and widget set similar to Motif or GTK+ in order to support other projects targeted at Linux and X Windows. The library includes a set of simple widgets (buttons, scrollbars, text fields, etc.), portable drawing routines, an automatic widget layout engine and image (pixel images) and picture (serialized drawing operations) support. Widgets may be added to the library as loadable object modules (plugins). The stdgui library is still under active development.
• Wrote the MIME-tool utility to generate MIME encoded email attachments supporting all encodings specified by RFC 2045.
