https://www.lukecall.net -- a tech-simple site with many thoughts on many subjects important to me, very skimmable but no ambition in visual style; nothing for sale until I get healthy and then if you want to pay for software development/systems consulting. Suggestions/questions welcome.

https://www.onemodel.org aka OM: available, effective, and in daily use, but progress on some planned new features is slow until health improves. A highly efficient (desktop) knowledge manager, text UI, Free (AGPL), using Scala and PostgreSQL (working to move to Rust and maybe later sqlite). Something like an efficient combination of mindmap, zettelkasten and GTD in one, with much greater ambitions including for linking instances for collaboration; see site links to screen shots for some idea of how I organize/categorize things. Low-volume announcements email list available (under "community").
