1+ hour, 9+ min ago   (304+ words) I kept losing track of where I was in long AI conversations — mid-decision, half-explored tangents, no clean way to close something out. I built a small set of rules to fix that. Sharing it because I want people to actually…...

A Prisma Schema Change Has Three Lifecycles

1+ hour, 13+ min ago   (132+ words) One valid PostgreSQL row refused to appear on my Next.js page. The relationship was correct, the SQL join returned the row, and the repository compiled. At runtime, however, Prisma returned an undefined jobOpportunity relation. I had changed the Prisma…...

Build an AI Moderation Classifier in Python

48+ min ago   (198+ words) Moderation is one of those product features where "just ask an LLM" sounds tempting, but it is not always the best workflow. Some content is obvious. Known spam, repeated abuse patterns, and common scam text should be caught quickly and…...

We Built a Text-to-SQL Agent for SAP. Here’s Why We Had to Rethink Everything.

1+ hour, 18+ min ago   (1221+ words) How governed SQL, a medallion semantic layer, and three query engines make enterprise data actually queryable — without hallucinated column names.

citesure 0.2: CourtListener case law and CJK title matching

1+ hour, 39+ min ago   (388+ words) LLM-written bibliographies do not stop at arXiv preprints.
