A-Shape Open Chord Variations
Every common variation on the open A chord -- sus2, sus4, minor, sevenths, sixth, add9 -- each one a single change from the base shape, with fingering and intervals shown side by side.
read moreSupports that peel off: a Bambu Studio profile that stops fighting back
The nine Bambu Studio support settings I change from stock for a 0.4mm nozzle at 0.16mm layer height, and why each one matters when you are trying to get supports off without damaging the part.

Why a flip-flop can stop between the rails, why two gates reading that voltage can disagree with each other, and why the bug that follows never reproduces.

A Knipex Cobra XS, an Opinel No 08 and a bit driver measured against a Leatherman Wave+ on weight, price and capability.

Why a design can pass sign-off timing and still fail in silicon, and the machinery that decides it: what synthesis optimises, what static timing analysis actually proves, SDC exceptions and the damage they hide, reading a timing report, RTL versus tool fixes, and multi-corner multi-mode closure.

Why a static CMOS gate is always inverting, how series and parallel transistor networks turn into NAND and NOR, why NOR2 is the slower of the pair, and where the extra two transistors in an AND gate go.

How to tie a clove hitch and a tripod lashing, and the wrap and frapping counts that let three poles open into a tripod.
