What Airflow or Dagster is worth at 5, 50 and 500 pipelines, costed in operator minutes, and the threshold below which we won’t sell a build.

A working demo tells you nothing about your next change. How to build an evaluation set from real questions, score retrieval separately from the answer, calibrate the judge, and gate every prompt change in CI.

Why the Claude Code install line fails in Command Prompt, the four errors that name your shell, and the 599-build gap before WSL 2 exists.

Five things payment code needs from the first commit: an idempotency key scoped to an intent, integer minor units, an append-only ledger, a replay-safe webhook handler and a nightly reconciliation against the provider.

EPSS scores how likely exploitation is in 30 days; CVSS scores how bad it would be. The arithmetic for a 400-item backlog, and the threshold we defend.

Why full reloads get slow, how log-based change data capture fixes it, what has to be in place in the source database before it is safe, and when reloading the lot is still the right answer.
