CLI for Your Notes in The Archive – Automated Zettelkasten (Usage) for Programmers

Apr 28th, 2026

Recently on a meetup, I was asked whether the age of manual note-taking and Zettelkasten is over now that LLM’s are everywhere and can produce so much text in such a short time that humans can’t outcompete them anymore. Outcompeting a computer on producing text was never the goal, of course.

Working with Process Pipe and Its 64KiB Limit

Mar 31st, 2025

Helge Heß pointed out that naive usage of Pipe in child Processes can break your program if you pipe too much data. I wasn’t aware of this, followed his references, and here are my findings. Older Mac OS X versions had a pipe buffer size of 16KiB by default, offering 64KiB on demand; in my N=1 test on an M1 with macOS 14, I always get 64KiB buffers, even if I only send 1 Byte. Run pipe buffer size discovery tests yourself to check.
