RT @jussisaur:

Let us know what you are thinking about the CDC approach in Limbo!. We plan to do more things around CDC so, for example, you can fetch updates from one database and apply them to another, or rollback changes granularly from some bad statement in the db.

I usually work on the platform side so I have a small context about turso-db code organization, but prototyping the feature was very smooth and took me just a few hours to get done!.

RT @glcst: Turso, the next evolution of SQLite, is written from the ground up with Deterministic Simulation Testing, in-house, and using @A….

Numberphile channel has a nice video about look and say sequence with a bit of a history behind the problem from John Conway: (Conway interviews are one of the greatest videos on the channel in my opinion).

Spent time reading SQLite caching code and seems that it resets a page cache for connection if writes were committed from another connection (.Looks like for workload with some writes there will be constant cache trashing.What the reason behind this logic?.

RT @rauchg: The @tursodatabase team was ahead of the vibe curve. Lightweight unlimited SQLite databases that you can create with one API ca….

It is well known that the Vertex Cover problem is NP-complete. But what if we consider a continuous version of the task where value v_x \in [0. 1] assigned to each vertex such that for every edge (a b) the constraint v_a+v_b >= 1 holds. Is this version in P or still NP-complete?.

Today I committed a crime and broke compatibility in my golang library for parsing djot markup lang. I know only a couple of uses for the lib so I decided that simple "hack" which will guide "unlucky" users a little will be enough. But still feel ashamed. Sorry for that, guys!

RT @leanprover: Lean community members Yaël Dillies and Paul Lezeau explain #LeanLang simprocs, or "custom simplification procedures", and….

I learned quite a few things while helping Jamie with his Go journey. Turned out that the zap logger AtomicLevel instance is actually an HttpHandler which you can easily expose for internal use and change log levels dynamically without app restart!.

Slides from the talk: It was nice to present libsql vector search, although in year 2025 I should present Limbo vector search instead (which is not even started yet, what a shame)!.

RT @DmitryRybin1: We discovered faster way to compute product of matrix by its transpose!. This has profound implications for data analysis….

Expressiveness of Lean4 blows my mind. Here, I define chain of codecs and immediately prove that resulting codec will be loseless (given that original one preserved information). Pretty amazing!

Proof if anyone interesting:

I spend today coding in Lean and now I have a formal proof of Fine-Wilf periodicity theorem in 270 lines of code! During the journey I even coded my version of induction which resembles Euclid algo single step.Encourage everyone to look into Lean as this is truly unique language!.

RT @GeorgePirlea: 🚨 New tool & paper! 🚨 .We’re excited to introduce Veil, a framework for verifying distributed & concurrent systems both….

Pattern matching in Rust is so great that for many scenarios this is the only thing you need for routing!.For example, that's how our HTTP server code looks like without use of any fancy libraries:

Very interesting talk from Terence Tao about future of math and usage of AI and computations to modernize math research. Lean4 looks very interesting (with a lot of exciting on-going projects happening like formalization of Fermat Last Theorem proof).
