Ugly little analog clock for terminal (bash + awk)

Around 30x30 chars ascii analog clock for the terminal, mostly written by chatgpt.
https://raw.githubusercontent.com/brontosaurusrex/bucentaur/refs/heads/master/.experiments/bin/clockascii

Config: To change aspect to fit your specific terminal, change ASPECT variable.

Note, to test drawings, one can use faketime command

faketime '13:37:00' clockascii

Maybe better sizes for hands:

HOUR_LEN=7
MIN_LEN=10

or the one where minute hand overrides the ticks:

HOUR_LEN=8
MIN_LEN=13

It’s always a good idea to work with virtual environments for any Python project. It keeps different bits of code and dependencies ringfenced from one another …

Helix, A Neovim inspired editor, written in Rust (update)

By starting from scratch we were able to learn from our experience with Vim and make some breaking changes. The result is a much smaller codebase and a modern set of defaults. It’s easier to get started if you’ve never used a modal editor before, and there’s much less fiddling with config files.
