I remember discovering minifeed.net not too long ago here on HN. Cool project! I like how you show related posts from other blogs when viewing an item. It's nice for discovering new blogs.
- freetonik 2y agoThanks! I still don't feel ready to do a proper "Show HN" with it though :) The related posts are generated with the help of a vector database (Cloudflare Vectorize [1]). I take post titles and descriptions as input, vectorize and store the results in the vector DB. Then for each post, I find 10-15 related posts and store the results in a separate table (it's a plain one-to-many SQL table). This is done because querying the vector DB is not super fast, and I wanted Minifeed to load under 500ms (according to my status page tracking, users in Europe for some reason experience the fastest loading times of 100-200ms! [2]). I also set up a scheduled job which regularly updates the relations (since there are new posts every day, and some of them may become "related" to existing posts). I've been meaning to write a blog post about the overall architecture of Minifeed, there are lots of small components related to RSS parsing, updates, caching, etc. 1. https://developers.cloudflare.com/vectorize/ https://developers.cloudflare.com/vectorize/ 2. https://status.minifeed.net/ https://status.minifeed.net/
- rednafi 2y agoDo a write up on explaining the architecture and maintenance cost. This looks sleek. It'll fly on hackernews.
