The Wall Street Journal ran a piece yesterday on JustPaid, a 9-person Mountain View startup. They used OpenClaw and Claude Code to stand up seven AI agents that write code, review it, and run QA around the clock. In one month: 10 major features shipped. Each one would have taken a human engineer a month or more. This story is getting passed around as proof that the autonomous engineering team is h
PostgreSQL Query Rewriting Techniques The previous articles in this series covered performance problems you fix by adding indexes, restructuring joins, or tuning memory. This one is about the queries where the plan is "fine" — every node is doing something reasonable — but the query itself is asking the wrong question, producing unnecessarily large intermediate results or forcing the planner dow
When you use window functions in SQL, you can't filter their results directly in a WHERE or HAVING clause — that's a well‑known limitation across many databases. GBase 8a, the China‑domestically developed MPP database from GBASE, solves this elegantly with the QUALIFY clause. Let's break down how it works, what it can do, and where you need to be careful. DROP TABLE IF EXISTS emp; CREATE TABLE emp
Si usas Claude Code para programar ya sabes lo que pasa: abres una nueva sesión y el agente vuelve a improvisar. El contexto de la sesión anterior desapareció. Le describes la feature de nuevo, asume cosas distintas, y acabas corrigiendo código que nadie pidió. OpenSpec resuelve exactamente eso. Es un CLI open-source que inserta una capa de especificación versionada dentro de tu proyecto. Claude C
DeepClaude: I Combined Claude Code with DeepSeek V4 Pro in My Agent Loop and the Numbers Threw Me Off DeepSeek V4 Pro correctly solves 94% of deep reasoning tasks in my loop… but the latency cost makes it unusable for 60% of my agent cases. Yeah, you read that right. And that completely blows up the narrative of "combining models is always better." Tuesday night I watched the DeepClaude post cli
DeepClaude: combiné Claude Code con DeepSeek V4 Pro en mi loop de agentes y los números me desconcertaron DeepSeek V4 Pro resuelve correctamente el 94% de las tareas de razonamiento profundo en mi loop… pero el costo de latencia lo hace inutilizable para el 60% de mis casos de agente. Sí, leíste bien. Y eso cambia completamente la narrativa de "combinar modelos es siempre mejor". El martes a la
As data grows, you'll likely need to add nodes to your existing GBase 8a MPP cluster without downtime. This hands‑on guide walks through the full process of adding a composite GNode to a running GBASE cluster. Existing cluster: A healthy GBase 8a cluster New node: A server with a static IP address configured Network: All nodes must be able to communicate with each other Stop services on all existi
Si tu as 30 secondes. La mémoire versionnée d'un workflow Claude Code a un effet de bord que personne ne signale : une règle mémorisée qui colle au symptôme de manière plausible court-circuite la vérification, même quand elle ne s'applique pas au compteur précis que tu regardes. Je me suis coûté vingt minutes d'exploration SQL la semaine dernière parce qu'une règle de la forme du bug — sans en êtr
