Rebuild notes
What we changed in our own apps and why, including the decisions we got wrong and reversed.
- Rebuild note
Twenty-three names cleared for trademark, none for a domain
Twenty-three names through four rounds of clearance, two finalists whose domains were registered in 2011 and 2023, and 140 replacement domains tested by RDAP. - Rebuild note
Four tests that could not fail
Four guards in Quilore that passed while unable to fail, a suite of 409 that stayed green against a file that would not parse, and 68 that passed on a share card printing two lines in the same place. - Rebuild note
Spotify's timestamp is the end of a play, not the start
137,153 back-to-back plays from a real 160,634-record Spotify export, and the 83.5 per cent against 0.3 per cent that settled which end of the song the timestamp marks. - Rebuild note
Android notification channels do not change their mind
Two sound failures in StudyPomo, five selectable chimes, and the channel id that encodes the choice. - Rebuild note
The part of Ponderanda that will never carry an advertisement
Ponderanda, live on Google Play since 17 August 2026. The daily ladder carries no advertising, the back catalogue is uncapped, and both are checkable by installing it. - Rebuild note
A foreground service, a wake lock, and a TECNO that ignores both
Sixteen builds of StudyPomo 1.0.0, and a foreground service measured dying on a TECNO KM7. - Rebuild note
The release build is not the app you tested
Two release-only failures in StudyPomo, and the keep rules that are still in the shipped 1.0.0 mapping.
