Short notes I keep coming back to — mostly what I've learned building.
a library nothing leavesIf I ate it once I’ll eat it again — so nothing gets deleted, and the order has to come from somewhere other than me.engineeringAug 17, 2026test the habit before you build the toolThe storage was a solved pattern; the risk was whether I’d type six entries a day for a month. So I tried the typing first, with no tool at all.engineeringAug 16, 2026fail-closed, and still surprisedA refusal that only fires at use-time can hide broken for months.e2eeJul 30, 2026put the rescue before the overwriteFour writes, four crash points — the order you write them in is the recovery story you chose.engineeringJul 30, 2026rotate the key, keep every promiseRe-encrypting everything is easy; never having a moment where something can’t decrypt is the job.e2eeJul 24, 2026retry before you write the root cause downA confident diagnosis confirmed by a confounded fix is still a guess.engineeringJul 24, 2026end-to-end has a server in the middleBrowser E2EE trusts the origin to serve honest code — the one gap crypto can’t close.e2eeJul 22, 2026right bytes, wrong addressA valid auth tag proves the ciphertext is intact — not that it’s the one you asked for.e2eeJul 14, 2026when my test suite showed up in my analyticsA test that hits a public recorder is a write — local runs must be forced secretless.engineeringJul 14, 2026the backup that needed no encryptionWhen everything is ciphertext, a backup is just the same bytes on a different disk.e2eeJul 14, 2026
