A gentle introduction to postgres wire protocol in Go

I kept hearing about the term wire protocol especially Postgres wire protocol in the recent days (Looking at you cockroachdb, yugabytedb - in a good way) but never really quite understood it. Decided to implement something simple in Go to understand it better. As always, if you find anything wrong or I misunderstood please correct me. Refer https://www.postgresql.org/docs/current/protocol.html and https://www.postgresql.org/docs/current/protocol-flow.html . If you are like me who has seen those links multiple times but didn’t know how to implement something using that, then this is for you :) Also, if you just want to get to the code, it is here . The first step is…from viggy28.dev

  PGlite – in-browser WASM Postgres with pgvector and live sync2024 · pglite.dev · ▲509

  Hey, Sam and the team from ElectricSQL here. PGlite is a WASM Postgres build packaged into a TypeScript/JavaScript client library, that enables you to run Postgres in the browser, Node.js and Bun, with no need to install any other dependencies. It's 3mb Gzipped, now has support for many Postgres extensions, including pgvector, and it has a reactive "live query" API. It's also fast, with CRUD style queries executing in under 0.3 ms, and larger, multi-row select queries occurring within a fraction of a single frame. PGlite started as an experimental project we shared on X, and the…

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  GPT-4-powered web searches for developers▲1,401

  Hi HN, Today we’re launching GPT-4 answers on Phind.com, a developer-focused search engine that uses generative AI to browse the web and answer technical questions, complete with code examples and detailed explanations. Unlike vanilla GPT-4, Phind feeds in relevant websites and technical documentation, reducing the model’s hallucination and keeping it up-to-date. To use it, simply enable the “Expert” toggle before doing a search. GPT-4 is making a night-and-day difference in terms of answer quality. For a question like “How can I RLHF a LLaMa model”, Phind in Expert mode delivers a…
