on GLM-5.2 Claims Top Open-Weights Spot on Artificial Analysis

i've been experimenting with glm-5.2 and it's impressive to see how it matches proprietary models on agentic tasks, definitely considering it for my next project since the mit license gives us so much flexibility

on PostgreSQL 19: Native Temporal Tables Are Finally Coming

i've been using the timescaledb extension for temporal data, but native support in postgres 19 is a game changer - no more complex exclusion constraints or custom indexing workarounds 🙌
