• My Formatter Would Have Rewritten This Test Into a Different Test

  There’s one line in my serializer test suite that carries a comment longer than the assertion: // The hole is the point. `biome check --write` rewrites this to // [1, undefined, 3], which still passes while testing something else // …

• The Registry Rewrote My Import and My Catch Block Covered For It

  Users installing my logger from JSR were getting this at runtime: [logan-logger] Winston not found, falling back to console logging: Error [ERR_MODULE_NOT_FOUND]: Cannot find module …

• An Empty Environment Variable Is Set. My Code Disagreed.

  LOG_TIMESTAMP="" is not the same as not setting LOG_TIMESTAMP. One of those is a user who typed something and got it wrong. The other is a user who never typed anything. My config loader collapsed them into the same branch, and the bug it …

• Six Dependabot PRs, Zero Merged

  Dependabot opened six pull requests against my wiki repo over the last two weeks. I merged none of them. I closed all six and replaced them with two hand-assembled PRs, and then I wrote a unit test so it wouldn’t happen a third time. The …

• My Test Agreed With My Bug

  The fix was one character. I appended "s" to a string. That’s the entire diff in the file that mattered: func printTimeoutValue(timeout time.Duration) string { seconds := int64(math.Ceil(timeout.Seconds())) if seconds < 1 { seconds = 1 } …

• A Dependency Bump Changed the Shape of My Vectors

  The commit is titled feat(deps): consolidate dependency updates. Sounds like a Tuesday. Bump some carets, watch CI go green, move on. What it actually did was cut every embedding in the database in half and rename the table they live in. …

• I Spent a Weekend on My Search Library and Deleted Its Best Feature

  A couple weekends ago I shipped nine releases of libsql-search, from 0.3.0 up to 0.11.0. The headline change is that I took out the local embedding feature. It used to generate embeddings locally. No API key, no account, no provider. You …

• I Gave Install-Script Permission to a Package I Don't Have

  There’s exactly one file in one of my wiki projects that’s a security control rather than a config file, and I hadn’t read it in months. pnpm 11 removed onlyBuiltDependencies along with four related settings and replaced all of them with a …

• My Logger Documented Four Environment Variables. None of Them Worked.

  I shipped a logging library with a LOG_LEVEL environment variable. The README documented it. A dedicated docs page documented it with examples and runtime-specific caveats. There were unit tests covering it, and they passed on every CI run …

• My Rate Limiter Documented Its Own Bypass

  I went looking through the rate limiter on a docs search API this weekend and found a comment I’d written explaining exactly how to defeat the code directly underneath it. Not a TODO. Not a “we should probably fix this someday.” An …
