Stories
Every hard part of Typoena got measured before it got improved. These are the write-ups behind the curtain: the real problem, the guesses the numbers ruled out, and what finally moved. The charts and tables are interactive — poke at them.
Kaizen · enclosure
The posts were floating
Analysis · 2026-08-10
Three posts tied the base of the case to its body. Two of them shared no space at all with the case they were bolted to, and the thing holding them up was the screen mount whose screw holes they were filling in.
1.7 mm³→1440 mm³
Kaizen · enclosure
The boss that held nothing
Analysis · 2026-08-10
A CAD model will happily hold two solids in the same place and never say a word. The posts meant to clamp the screen ran through the bracket they were holding, and only an intersection test could see it.
277 mm³→0 mm³
Kaizen · typing latency
The wall behind every keystroke
Analysis · 2026-07-16 – 07-21
Three chained kaizen rounds on the gap between a keystroke and its pixel: the obvious fix refuted, then everything that wasn't the e-ink waveform drained away, until only physics was left.
693 ms→527 ms
Kaizen · git sync
The memory war
Analysis · 2026-07-13 – 07-14
A ten-minute freeze a reset couldn't fix, and nine tries to push a 263 MB repo through 8 MB of RAM.
∞→24.1 s
Kaizen · boot latency
Two and a half seconds too slow
Analysis · 2026-07-17
Removing the pre-app overhead — then watching a faster CPU spring a hidden lock-contention trap.
4159 ms→3239 ms
