Supercharge vector search with ColBERT rerank in PostgreSQL (vectorchord.ai)
Traditional vector search methods typically employ sentence embeddings to locate similar content. However, generating sentence embeddings through pooling token embeddings can potentially sacrifice fine-grained details present at the token level. ColBERT overcomes this by representing text as token-level multi-vectors rather than a single, aggregated vector. This approach, leveraging contextual late interaction at the token level, allows ColBERT to retain more nuanced information and improve search accuracy compared to methods relying solely on sentence embeddings.

Back to basics: Why we chose long-polling over websockets (inferable.ai)
Like many teams building real-time systems with Node.js and TypeScript, we've been exploring ways to handle real-time updates at scale. Our system handles hundreds of worker nodes constantly polling our PostgreSQL-backed control plane for new jobs (tool calls issued by agents), while agents themselves continuously pull for execution and chat state updates. What started as an exploration into WebSockets led us to a surprisingly effective "old-school" solution: HTTP long polling with Postgres.
