He also did this one when I was the maintainer of libgit2. He's very good at this!

Banger blog post from the Turbopuffer team. Great breakdown, great interactive visualization and obviously a great implementation like they always do.

BM25 efficiently scores text, but relevance often depends on more than text (recency, popularity, PageRank)
we score non-text attributes as clauses in the same MAXSCORE plan that evaluates BM25 → better first-stage relevance, still scales to 100M

We've been developing a multi-agent system that builds and maintains complex software autonomously.
Recently, we partnered with NVIDIA to apply it to optimizing CUDA kernels.
In 3 weeks, it delivered a 38% geomean speedup across 235 problems.

I've just dropped a Mirror of Kalandra playing Path of Exile. That's... an extremely uncommon thing.

I've heard some people say that Composer 2 is "just Kimi 2.5", which is easy to disprove if you look at any benchmarks... or, huh, if you run the model for like 30 seconds. Anyway: this paper shows the humongous training effort that went behind our model. Please check it out.

This is my first post on the Cursor blog: an interactive survey on the state of the art for n-gram indexes.

Cursor can now search millions of files and find results in milliseconds.
This dramatically speeds up how fast agents complete tasks.
We're sharing how we built Instant Grep, including the algorithms and tradeoffs behind the design.

This is our first truly SOTA model. It's amazing what you can accomplish when you only train for writing code.

Story time!
The very first version of Bugbot we launched was stateless. We kept track of runs in our analytics database and we only used that data offline for metrics. Whenever we needed to analyze run metadata, we had to do online lookups from the database.
Relying on our analytics database during online operations was definitely tech debt. We were using a large RDS cluster that was already running hot from offline usage. We started noticing that some Bugbot runs were failing because of external analytics load; by that time, we had added a few Bugbot-specific tables to it, so we had to come up with a migration plan quickly before this became a widespread availability issue.
We chose PlanetScale Postgres for our new Bugbot cluster. We already had many terabytes of data in PlanetScale MySQL/Vitess which was working incredibly well, so we felt comfortable with this choice.
The migration went very smoothly, and now all of Bugbot's queries are instant and we stopped worrying about downtime!

Earlier this week, SpacetimeDB launched v2 of their product with a weird marketing video. It was full of memes, and mocking other databases; their CEO showed up drinking "competitor's tears". I found it off-putting, but it did pique my interest enough to do a technical review of their product.
In summary: it's not a very good database, and it is a big marketing miss. Database marketing is hard! They had a good chance to launch this and make people go "Wow! It's like Redis on steroids! You can build a whole MMORPG on top of this!". But instead they invited some very awkward comparisons with their benchmarks.
Any technical person who looked at their offering probably thought: "Wow, 190k QPS in a relational database? I wonder what's the catch".
The catch is that it's pretty much just an in-memory hash table with a single lock in front of it. Some interesting ideas, some big footguns. But that's pretty much it.
Here's my full technical review, including some thoughts on database marketing, if you're interested 👇

Y'all database nerds really love fighting in twitter huh.
FWIW I don't have a particular horse in this race. I used to work at PlanetScale but I've escaped the permanent database engineer underclass now (hashtag blessed). I also don't know anybody at SpacetimeDB, but I've played a couple dozen hours of their MMORPG and I actually like it lol.
The technical descriptions in the blog are, I think, accurate to the extent of my ability and the 15 minutes I spent reading the code. If you think I got details wrong, you may be right!
The non-technical descriptions in the blog are, I think, accurate to the extent I have good taste. If you think I got anything wrong, you're wrong (and have bad taste).
Now if you'll excuse me, my toddler is asleep and I got a hot date with my wife and the Dominos delivery guy. Please enjoy database twitter drama responsibly.

RIP to one of the great startups of Web 2.0. The times, they are a-changin'.
Heroku is transitioning to a sustaining engineering model focused on stability, security, reliability, and support. Heroku remains an actively supported, production-ready platform, with an emphasis on maintaining quality and operational excellence rather than introducing new features. We know changes like this can raise questions, and we want to be clear about what this means for customers.
There is no change for customers using Heroku today. Customers who pay via credit card in the Heroku dashboard—both existing and new—can continue to use Heroku with no changes to pricing, billing, service, or day-to-day usage. Core platform functionality, including applications, pipelines, teams, and add-ons, is unaffected, and customers can continue to rely on Heroku for their production, business-critical workloads.
Enterprise Account contracts will no longer be offered to new customers. Existing Enterprise subscriptions and support contracts will continue to be fully honored and may renew as usual.
Why this change
We’re focusing our product and engineering investments on areas where we can deliver the greatest long-term customer value, including helping organizations build and deploy enterprise-grade AI in a secure and trusted way.

Madre mía, cómo deben de ir las encuestas pa que la tipa esta esté haciendo cosplay del Comandante Fidel con un chándal Adidas. Están rascando el fondo del barril y no les sale nada. Me meo.

Nos comunicamos de forma urgente con la Comisión Europea para exigirles actuar conforme a la legalidad internacional contra EEUU ante su agresión militar ilegal contra Venezuela y para garantizar la liberación de su Presidente y de todas las personas ilegalmente secuestradas.
