Small tools for the hundredth time you do it.

I write software for the parts of a desk that get used every hour and noticed only when they misbehave.

Projects

nidaba
  • Coming soon
  • macOS
  • Linux

Your SSH hosts and keys on every machine, in the config you already have. Connect with plain ssh — nidaba only writes the file.

  • Your ~/.ssh/config stays yours — nidaba adds one Include line
  • Keys reach ssh through an agent, never a file on disk
  • Planned: end-to-end encrypted sync — the server will hold only ciphertext
See how it works
Nomos
  • Early access
  • macOS 26+
  • Free

A window manager for macOS. Zones from every display are threaded onto one ring, so a single key walks a window through every place it can go.

  • Move windows across monitors with one key
  • Custom zones on each screen, portrait included
  • Rules for apps that always open in the same zone
See how it works
auditrum
  • PyPI
  • Python

Auditing for Python applications.
pgtop
  • crates.io
  • CLI

A console utility for monitoring PostgreSQL activity — pg_activity in a terminal you can keep open all day.

Every window manager I tried carried a window’s proportions across monitors. Dropping that idea turned out to remove most of the code, not add to it. All writing
