Distributed Locks

38+ min ago   (110+ words) One-liner: A distributed lock ensures that only one node in a cluster can perform a critical operation at a time — preventing race conditions across services. In a single-server world, a mutex or semaphore handles concurrency. But in distributed systems: Classic…...

Treating “one day” as a system primitive

1+ hour, 38+ min ago   (165+ words) For most AI apps, the unit of time is a request. A user sends a message, the model responds, and the workflow ends. Cogweald is designed around a different primitive: one real day. Each world can advance by at most…...

When a Zero-Parameter Cache Overtakes a Transformer

1+ hour, 38+ min ago   (574+ words) The question this series exists to answer, put in a form that can be measured: a transformer sees a fixed 64-token window, a count table over the current document sees the whole document, and as documents get longer, how much…...

Why Parameterized Queries Matter for SQL Security

1+ hour, 37+ min ago   (559+ words) SQL injection is one of the classic examples of what can happen when an application mixes user input directly into a database query. The underlying problem is simple. The application expects data. The database may interpret part of that data…...

Recursive CTEs: How SQL Secretly Learned to Loop

2+ hour, 32+ min ago   (454+ words) Ask a SQL query to find "all employees under this manager," and things get ugly fast if you don't know how many levels deep the org chart goes. A regular join handles one level. Two joins handle two levels. Nobody's…...

I Replaced Chroma, Qdrant, and Pinecone With a SQLite File

I described 1,245 tables with an LLM and retrieval got worse

5+ hour, 1+ min ago   (1126+ words) The cataloguing step is supposed to be the easy win. You have a schema whose tables are called ecm_template_link and v_pmpm, your users ask questions in English, and the gap between those two vocabularies is why retrieval misses. So you point a…...

5+ hour, 1+ min ago   (955+ words) Spider, BIRD, LiveSQLBench. If you have evaluated a text-to-SQL system in the last five years you have quoted a number from one of them. All three ask the same question: given a schema and an English question, does the system…...
