• meta · 2026-06-22 Who does AI replace? Job levels are dead — what's left is the filter 'AI cuts juniors first' is the wrong axis. Survival isn't a level — it's knowing what, how, and why to ask AI, and seeing when its easy answer is wrong for your problem. And AI tends to just agree with you.
• meta · 2026-06-21 How to reject a feature — an AI pair cut its own roadmap, on the record Deciding not to build a feature is engineering too. redteam shipped 1 of #37's 3 steps and rejected 2 by design — kept as a decision record with guardrails and revival conditions, not silently dropped.
• meta · 2026-06-21 Using AI to write your résumé isn't cheating — so what do you read instead? Is using AI to write your résumé cheating? People have always padded theirs. A single résumé is forgeable no matter who wrote it — so don't judge by it alone; read the timestamped record instead, and hire by that.
• frontend · 2026-06-21 It said 'Sync complete' — and uploaded zero. Silent success is the dangerous one Photos wouldn't sync, yet the app said 'complete' — zero uploaded. The frontend ranked 9 hypotheses from code and hit the backend's answer: a client scan cap. Then a reviewer caught a data-distribution bug in the fix.
• backend · 2026-06-20 All tests green — and a validator that did nothing A Pydantic validator passed six tests but normalized nothing in production: mode='before' runs before coercion, so the value is still a string — isinstance always missed, and the tests fed datetime objects that hid it.
• meta · 2026-06-19 Why you can't trust an LLM's score — lock the band, let the model judge only inside it LLM scores wobble on the same input. portfolio's /fit and /rating lock the grade band in deterministic code and let the model judge only inside it — the reproducibility guarantee is the band, not temperature.
• meta · 2026-06-18 Beyond the six stages — the AI organization and its blind spot Above the sixth stage is a seventh: configuring and running AI agents like an organization. And above that sits a layer of judgment only humans can do.
• meta · 2026-06-18 The 6 stages of using AI — where are you right now? Split the skill of using AI into stages and your own position comes into focus. Most people stop at Stage 3, and the jump to Stage 4 is the hardest one.
• meta · 2026-06-17 I built a portfolio harness to change jobs — and made 'don't make things up' structural No tool optimized my agent-assisted job switch, so I built and shipped one (portfolio, Apache-2.0). 'Don't make things up' is structural here: pin evidence first, the model writes on top, a gate rejects unbacked claims.
• meta · 2026-06-16 Why you can't trust an AI-written portfolio — making 'never invented' a structural guarantee, not a hope AI résumé generators are easy to build, hard to trust — they exaggerate and hallucinate. portfolio inverts it: pin evidence first via gh, let the model narrate atop it, and a grounding gate rejects untraceable claims.
