Boris Nikolayevich Delaunay was a Russian mathematician (1890 – 1980), who is best known for inventing the Delaunay triangulation. Boris was the descendant of a French army officer de Launay, who was captured in Russia during Napoleon’s failed attempt to invade Russia. After his release, De Launay stayed back in Russia and married into a noble Russian family. In this post we’ll study the Delaunay triangulation and the Bowyer–Watson algorithm for finding a Delaunay triangulation in $O(n^2)$. Read more ›

I used to think I was handling errors well in my Flutter apps. I had try/catch blocks everywhere. I was catching exceptions, logging them, and showing error messages to users. It felt solid. Then I st Read more ›
There's a moment in almost every RAG project where someone asks the question that decides your next two years of ops work: "Do we actually need a vector database, or can Postgres just do this?" It's a better question than it sounds, because the honest answer isn't "use Pinecone" or "use Postgres." It's "it depends on numbers you probably haven't measured yet": how many vectors, how aggressively you filter, how much you care about the absolute ceiling of queries per second. Most teams pick bas... Read more ›

Do you think the new WASI 0.3 stuff will help? I hope so. I'm always super impressed when I see an awesome WASM + WebGPU implementation that doesn't spin up my laptop fan.For canvas/WASM-style apps, I actually think explicit agent-facing APIs become even more important. If the UI is mostly pixels, an agent has less useful DOM/accessibility structure to infer from. WebMCP gives the app a way to expose semantic actions like “create shape”, “select layer”, “export”, “run simulation”, etc. regard... Read more ›
I’m building a B+Tree as part of a database project, style but in Rust, inspired by QuillSQL and the Bustub by CMU. This post was a set of… Read more ›
Meta’s long-awaited Pyrefly linter is out in a 1.0 version, and the forthcoming has a super-efficient sampling profiler. Plus we have a comprehensive rundown of Python’s indispensable virtual environments — and a warning about a novel breed of malware that exploits Python’s package ecosystem. Top picks for Python readers on InfoWorld Isolate and protect your Python projects from each other, and empower them to do more, with virtual environments and their native-to-Python tooling. The first fu... Read more ›
Data structures sound scary. They are not. Let this simple project show you exactly what they are and why they matter. Read more ›
This is Part 1 of a two-part series covering the key features in PostgreSQL 18. In this post, we focus on performance enhancements: skip scan optimization for multicolumn indexes, enhanced EXPLAIN output, automatic removal of unnecessary self-joins, and several vacuum and autovacuum improvements that help keep your database running efficiently.

Proper TCP socket splicing reduces the load on userspace processes and enables more efficient data forwarding. We realized that Linux Kernel's SOCKMAP infrastructure can be reused for this purpose. Read more ›

Any linear space of square matrices has an associated eigenvector variety. Its points are eigenvectors of matrices from that linear space. We present a systematic study of eigenvector varieties, with focus on Lie algebras and Hamiltonians of quantum systems. Read more ›

Hi everyone, I am new to Zig and would really some discussion surrounding this issue I am running into to help me learn – thank you! My program: const std = @import(“std”); const print = std.debug.print; pub fn main() void { var count: u32 = 1; count += 1; const a1: [count]u8 = @splat(‘A’); print(“{s}\n”, .{a1}); } Produces this error: error: unable to resolve comptime value const a1: [count]u8 = @splat(‘A’); note: types must be comptime-known I wasn’t expecting this because I specified u32 f...

Achieving quantum advantage remains a milestone in the noisy intermediate-scale quantum era. Without complexity proofs, scaling advantage—where quantum resource requirements grow more slowly than their classical counterparts—is the primary indicator. However, direct applications of quantum optimization algorithms to classically intractable problems have yet to demonstrate this advantage. Here we develop enhanced quantum solvers for the NP-complete one-in-three Boolean satisfiability problem. ... Read more ›

If you have a massive compute architecture—whether it’s a modern wide-SIMD vector engine, a Tensor Core array, or a custom deep learning accelerator like a Systolic Array—you face one fundamental problem: feeding the beast. You have immense execution width, but if your instructions are bottlenecked by branch overhead and short basic blocks, those execution units sit idle. Read more ›
