TLDR; I'm making a Typescript type-checker in Rust. Right now it supports a smaller subset of the type-system and exists as a fun side-project, but the end goal is a compilation tool we can use to make Typescript compilation go brrrr...
Software design is a deliberate process, and requires deliberate effort.
How we built memchunk - a blazing fast text chunking library using SIMD and memchr for RAG pipelines
Full-text search is a powerful machine learning algorithm, especially relevant for web developers. This article teaches you the basics, from scratch.
Yes, the stats collector is gone from PostgreSQL 15, but there's lots of new exciting features to talk about!
I wrote a full featured application in rust, and so can you!
The boolean satisfiability problem (“SAT” for short) is arguably the most famous NP-complete problem in theoretical computer science. According to Wikipedia, it is “the problem of determining if there exists an interpretation that satisfies a given Boolean formula ”; or, in simpler terms, if there is at least one…
Apple announced OS X Yosemite today. Don't worry, Alfred is here to stay - and continues to grow beautifully.
Salvatore Sanfilippo, aka antirez released a telegram bot library in C recently. While I'm not at all interested in a telegram bot library, I always like to read Salvatore's code, which is uniformly superb.
We've spoken in the past about teaching Clang to fully support Windows and be compatible with MSVC. Until now, a big missing piece in this story has been debugging the clang-generated executables.
If you want to make a sound shorter, you can play it faster. Doing this also makes it higher pitch unfortunately. If you want to make a sound longer, you can play it more slowly. This also makes it…
Everybody counts, but not always quickly. This post looks into how the PostgreSQL database optimizes counting. In Postgres, there are ways to count orders of magnitude faster. We’ll look at exact counts (distinct counts) as well as estimated counts, using approximation algorithms such as HyperLogLog (HLL) in Postgres.
Visualizations and techniques for different maze generation algorithms.
Going in depth into the Address Sanitizer internals.
Support for spatial data and geospatial indexing is one of the most requested features in the history of CockroachDB.
This is the mail archive of the gcc@gcc.gnu.org mailing list for the GCC project .
In 2020, I started writing a 3D game engine from scratch in C++. This is a post about how I added skeletal animation to it. Drake is in it, so buckle up.
T5Gemma 2 is the next evolution of our encoder-decoder family based on Gemma 3.
At Hacker School , I've been building an alternate universe Python by overwriting builtin functions and statements with Harry Potter spells. This is a thing you can do at Hacker School!
The PyPy team is proud to release version 7.1.0 of PyPy, which includes two different interpreters: PyPy2.7, which is an interpreter s...
People involved in the day-to-day development of a project tend to become so familiar with its rhythm and process that they internalize it and it feels like everyone must just _know_ how each stage unfolds. Of course, from the outside looking in it's not so obvious. So I thought it might be helpful t...
The following Python function computes the Fibonacci sequence , without loops, recursion or floating point arithmetic:
