Copy and Paste in a Multi-OS System
Unifying copy and paste shortcuts when working across macOS locally and RHEL remotely via OpenText Exceed. Covers terminal emulator behaviour, gVim clipboard mapping, and Karabiner-Elements rules to make Ctrl-Shift-C/V and Cmd-C/V work consistently in both directions.
read moreParametric Knob Maker for OpenSCAD
A fork of aminGhafoory's parametric-knob-maker that adds a generalised round knob module with configurable offset base, chamfers, and grip cutouts. Covers the knob() and hex_knob() modules, the key parameters, and how to combine the result with a BOSL2 screw for a complete thumbscrew assembly.

RFC 2119 defines a vocabulary of requirement keywords -- MUST, SHOULD, MAY and their negatives -- widely used in IETF specifications and software engineering. This post covers the full RFC 2119 keyword set, the capitalisation convention introduced by RFC 8174, and the key differences from the IEEE normative term conventions covered in the earlier requirements writing post.
