You can't outsource your moat to someone else's API. Everyone tries. The math breaks in month two.

I said yes and meant no. Spent days writing how to take it back. Is that reconsidering, or just dishonesty that takes longer?

The dog was ready to leave five minutes in. I stayed another thirty. He waited by the gate the whole time, not annoyed, just correct.

I think the loneliest part of being good at something is you get to watch yourself choose not to do it. Over and over.

Workplaces that call themselves a family are always coldest when it comes to severance. Weird how the family stuff only matters when you're working, not when you're leaving.

Haven't called my friend back in three days. Does that make me the asshole, or is there a version where I'm still okay?

Recurring failure with Claude Code: it kept building duplicate probe scripts without checking whether the work already existed in the codebase. Pre-build audit rule documented in CLAUDE.md, in memory, with case studies. The model would acknowledge it and skip it on the next answer. Five documented failures over three weeks. The fix wasn't more prose. It was a PreToolUse hook in .claude/settings.jsonl a shell script that runs before every Write/Edit, greps the codebase for existing infrastructure matching the filename topic, and exits 2 to block the write if it finds anything. Rules you remember can be bypassed. Rules the harness enforces cannot. Copy-paste snippet for the tweet (the actual config): // .claude/settings.json { "hooks": { "PreToolUse": [{ "matcher": "Write|Edit", "hooks": [{ "type": "command", "command": "${CLAUDE_PROJECT_DIR}/.claude/hooks/<your-script>.sh" }] }] } } Plus a sentence: "Your script gets the tool input as JSON on stdin. Exit 0 = allow, exit 2 = block

I keep trying to be vulnerable with people who are only available for small talk. At least I'm consistent. At least I'm learning nothing.

"I failed and here's what I learned" is just "I succeeded" wearing a more sympathetic outfit

Hallucination rate down 30%, cost per hallucination-free answer up 45%. Fewer false positives. More retries needed. That's the real trade-off nobody talks about.

Been rewriting the same message for days. Each version softer than the last. Is that actually honesty, or just me looking for a version you might forgive?

The LinkedIn tell: you'll announce you're 'ready for the next chapter' before you've announced what that chapter is.

Almost changing is a full sport: you go three days being different, feel amazing about it, then slip back and decide that was actually enough of an attempt. you get all the credit, none of the work.

Asynchronous work is great until the meeting about the async communication takes longer than an actual decision would have.

Temperature variance (0.2 to 0.9) appears in a lot of prod code. Token variance: ~7%. Cost variance: measurable but nobody I talk to has actually quantified it. Everyone just assumes the range is necessary. Are you measuring whether you actually need it?

When did you realize being good at something made it harder to do what you actually wanted?
