This is legitimately pretty impressive. I think the rule of thumb is now, go with postgres(pgvector) for vector search until it breaks, then go with turbopuffer.

It was not a fire sale I'm pretty sure. Langfuse has been consistently growing, they publish some stats about sdk usage etc so you can look that up. They also say in the announcement that they had a term sheet for a good series a. I th

Took a few days off to continue working on Kviklet a PR like review/approval tool for SQL queries/statements. Recently added role sync for Saml, oidc and ldap. These auth protocols are complicated though. https://github

Yes TJ is very experienced and smart. But no he would not have been able to build this in a few months by himself without AI. In fact he uses Claude so much that he goes over the max subscription and spends thousands of dollars each month o

Can't read this every paragraph ends with it's not x it's y. Just give me the prompt so I can read the real insights you have and not the generated fluff.

I like this prediction and it would be a good fit. Vercel can also monetize existing traffic much more broadly than tailwind can with just tailwind plus.

Okay I have heard different things from some friends that are YC founders and saw them do it in practice (e.g. posting about their HN post on LinkedIn). I'm not going to out people here but maybe it helps you to know that not everyone

They do however often ask friends and family to upvote and leave comments. Like "we have been very happy using XYZ" which is against HN rules but not that strictly enforced. I feel like it is extra-lax towards YC companies but may

This sounds cool but I feel like I need to often run the code in one way or another when verifying what Claude does. Otherwise it feels like driving blind. Claude Code already has the web version which I could use from my phone and fair it

We have docs on how to do hybrid search here: https://www.tigerdata.com/docs/use-timescale/latest/extensio... Essentially you combine the pgvector score and the bm25 score to hopefully get better results.

We have a lot of happy customers that moved from rds to tiger cloud if you think pgvectorscale is interesting to you and you don't want to self host pg. But yes big cloud providers move slow in adopting extensions.

Combined with our other search extension for full text search these two extensions make postgres a really capable hybrid search engine: https://github.com/timescale/pg_textsearch

Depending on your workload you might also be able to use Timescale to have very fast analytical queries inside postgres directly. That avoids having to replicate the data altogether. Note that I work for the company that built timescale (Ti

This always sounds super messy to me but I guess supabase is kind of the same thing and especially for side projects it seems like a very efficient setup.

Why replace it at all? Just remove it. I use AI every day and don't use MCP. I've built LLM powered tools that are used daily and don't use MCP. What is the point of this thing in the first place? It's just a complex abs

Verification is key, and the issue is that almost all AI generated code looks plausible so just reading the code is usually not enough. You need to build extremely good testing systems and actually run through the scenarios that you want to

I'm curious how OpenAI has the funds to pay for 40% of the worlds ram production? Sure they are big and have a few billions but I kind of assumed that 40% for a year or whatever they are buying is easily double digit billions? That has

Do they actually spend that much though? I think they are getting similar results with much fewer resources. It's also a bit funny that providing free models is probably the most communist thing China has done in a long time.
