    I built an MCP server using Cloudflare's code mode pattern▲87

    Read this article by Cloudflare this morning https://blog.cloudflare.com/code-mode/ the main argument being that LLMs are much better at writing typescript code than tool calls because they've seen typescript code many more times. HN Discussion: https://news.ycombinator.com/item?id=45399204 https://news.ycombinator.com/item?id=45386248 Deno provides a great sandbox environment for Typescript code execution because of its permissions system which made it easy to spin up code that only has access to fetch and network calls. Stick an MCP proxy…

    Serverless OLAP with Seafowl and GCP▲54

    Hello HN! I'm an engineer at Splitgraph and recently started learning Rust so I could make my first contribution to Seafowl [0], an early stage analytical database. Along the way I figured out a database hosting hack on GCP and wanted to share it with HN. It's a way to achieve "true" scale to zero database hosting that could be useful for certain side projects or spiky traffic situations. A recurring problem I've faced with side projects is the need for Postgres, but no desire to deploy or maintain new instances. So when I learned GCP's "always free" tier includes serverless [1] I got…
