Been using for years for my freelance/consultant activity a bash-based environment with convenience enhancements: create context per client or project, get instant access to auto-created per-context-day working directory with easy navigation, per context environment + bash_history + logging of terminal content + ability to instantly create/edit timestamped files for note taking. Good productivity booster, helps a lot isolate clients, easily answer customer phone calls any time. Logging saved me a few times.

Been wanting for a long time to rewrite it into something usable by others. Been doing that rewrite during lockdown.

All this reuses existing tools and conventions, is lightweight, shell-completion friendly, easy to learn.

Also, written (again) a game for the 8bit computer Amstrad CPC of 1984, in clean modern C on a C compiler that understands most of C11. With optimized assembly for time-critical parts.

Both started earlier this year, got more time during lockdown.

I might offer a "show HN" for one or both. If you have any interest please tell.
