Retired, but having fun with Go. Writing a clean-room implementation of Rocket Software’s UniVerse database as a thought experiment, and to keep the head busy. C was fun, but Go may produce more robust code for a given level of effort.
A bit of a Linux administration noob, as the technology has changed from the days of tuning and building UNIX kernels 30 years ago, but generally survive. At least a career in performance tuning the database has kept my O/S skills somewhat up to date. CL is nice and responsive.
