42 Is Not a Random Number
MCP won and agents are everywhere, but they still fail in the same dumb ways. The fix isn't a smarter model. It's deterministic tools.

Beating BERT? Small LLMs vs Fine-Tuned Encoders for Classification
I ran 32 experiments comparing small LLMs to BERT on classification tasks. Turns out 2018-era BERT is still really good at what it does.

The Case Against pgvector
The real limitations of pgvector in production: index choice between IVFFlat and HNSW, why real-time search is hard, pre- vs post-filtering pain, how performance degrades at scale, and when a dedicated vector database is the better call.
