My previous HN post ( https://news.ycombinator.com/item?id=43299659 ) got some traction, and several folks reached out asking for the source code, so here it is! Rumor has it a certain dedicated vector database provider (whos

Thank you for the comment, compared to you I have only touched the bare surface of this quite complex domain, would love to get more of your input! > building HNSW indices in Postgres is still extremely slow (even with parallel index bui

> And overall, the fewer people use CF (or another provider of their size) the better. I understand your sentiment, but I vehemently disagree. The cloud provider space has rapidly become an oligopoly and CloudFlare is one of the few new

After this failed experience with SemHub, I am actually thinking of building something like this, for open source maintainers like you are definitely the ICP! (nuqs seems really cool btw, storing state in the URL param is definitely the way

Thanks for sharing! Do you have more details to share, e.g. did you just have a vector db, or did you have a main db as well? In my research, Qdrant was also the top contender and I even created an account with them, but the need to sync tw

Ah I was doing semantic search of GitHub _issues_, not the actual code on GitHub. For code search, I have used grep.app, which works reasonably well

oh wow that's super cool, I tried it and it's very fast indeed. thanks for sharing! will spend more time to understand how it's implemented

Thanks for the feedback, to be honest, my own experience is actually very similar to yours. The original pain point probably only exists for small minority of open source maintainers who manage multiple repos and actually search across them

> Have you looked into chunking (breaking input into smaller chunks and doing vector search on the chunks)? Ohh I had not seriously considered this until reading this. I could have multiple embeddings per issue and search across those em

Ohh apologies, I think there was a bug that led to the Internal Server Error, please try again, I _think_ it should be working now! > I think a project like yours is going to be helpful to OSS library maintainers to see which features ar

Totally fair point. Thanks for taking the time to read through it! I guess I didn't want to use a VPS and then have to switch to something else if the product really worked, but I guess that rhymes with premature optimization. Some oth

Author here. Over the last few months, I have built and launched a free semantic search tool for GitHub called SemHub ( https://semhub.dev/ ). In this blog post, I share what I’ve learned and why I’ve failed, so that other bu

It's always a little dubious when modern people pretend to have high confidence about the behaviors of long-dead people to serve their modern purposes. (Another example: oh you're an INFJ, just like Moses from the Bible!)

I met one of the founders of Coder.com, he's a really cool dude. It's a pity that it is a product aimed more at enterprises than individual developers, else it would have far more developer mindshare. Unlike, say, GitHub Codespace

Mildly interesting that the author runs a media relations company in SF. On the one hand, I am sympathetic to the general perspective of the original article. On the other hand, that the same person is writing “hit pieces” and running a med

Interesting stuff. We use MemoryDB as the underlying service for BullMQ, a NodeJS queue that’s built on top of Redis. We trade off a bit of speed and cost (MemoryDB costs more than Elasticache) for persistence and BullMQ’s many features, wh

I think Git itself is probably too entrenched to be displaced by now, but I recently came across Graphite ( https://graphite.dev/ ) and, while it’s all still Git under the hood, it abstracts away many of the common pain point
