While Full-text-search is famous for search through documents at a faster rate, there are other interesting ways in which these systems handle scale, synonyms, abbreviations, misspellings etc., we will
One of the things people often complain about when doing Async Rust is cancellation. This has always been a bit confusing to me, because it seems to me that async cancellation should feel a lot like panics in practice, and people don’t complain about panics very often (though they do sometimes). This post is the start…
Having just written rather a sad piece on my company’s blog, I thought I’d cheer myself up a bit — and explain a few things that have been hugely …
TLA+ is a formal specification and verification language intended to help engineers specify, design and reason about complex, real-life algorithms and software or hardware systems. We explore its motivation, application and principles of design.
Have you ever watched a school of fish, a flock of birds, or even a crowd of people and watched how they move?
Today I want to talk about an issue I was having with UDP sockets in Go, and how I learned more about my program by making use of two tools that ship with Mac OS X called dtruss, and DTrace.

Solving problems by identifying underlying systems
A couple of weeks ago, I started to work with Emacs, and I grow fonder of it every day. During a very short time period, it has become my go-to editor for nearly everything I do on my computer, including (but not limited to) planning my Todos (in org-mode, to be precise), setting up my agenda (org-mode again), taking…
A 3.8B model pretrained from scratch to 0.384 CORE on 65B tokens in 43 hours, for $998.
If you are anything like me, you appreciate solving your every day simple tasks directly from the command line. Creating crafty single shot command lines or a small shell script to solve that special task you figured out you needed and makes your day go a little smoother. A fellow command line cowboy. Video…
In order to understand what I’m going to talk about, you must know what is AWS Lambda, I talked about in this blog post where I went through getting started with Visual studio code and AWS Lambda, …
Adding multi-scale noise layers, mountain distance fields, and elevation blending to create detailed terrain from the paint map foundation.
The result of my exploration of Elixir clustering and automating global network discovery and connection over Tailscale.
Why WSGI is not as big of a problem as you would believe and why framework independent pluggable applications don’t work in practice.
I tried to boot an iOS 12 kernelcache in QEMU: I managed to get as far as IOKit startup before receiving a kernel panic. I learned a lot about how iOS boots up with this project.

Kristoffer over at rpsychologist.com wrote a really nice tutorial on getting up to speed with maps in R. It looked something like this.
One of MRI's big performance problems is that method cache expiry is global. That is, any time you make a change to any class anywhere, the entire VM's method caches get busted at the same time. This is why you'll frequently hear people saying that "calling Object#extend is bad".
A floating point number f has the form f = m · 2 e where m is called the mantissa and e is a signed integer exponent . We like to read numbers scaled by powers of ten, not two, so computers need algorithms to convert binary floating-point to and from decimal text. My 2011 post “ Floating Point to Decimal Conversion is…
I have worked on optimizing the standard library deflate function, and I am happy to announce revised gzip/zip packages, that on x64 is about 30-50% faster with slightly improved compression. Project: https://github.com/klauspost/compress All packages are drop-in replacements for the standard libraries, so you can use…

This post describes the implementation of pysmtgcc. See “GCC Translation Validation” for background information.
Tangent space is often presented as a confusing block of shader math. This is a deep dive into what tangent vectors actually mean, how they emerge from UVs to bridge 2D and 3D space, and the geometry that makes normal mapping possible.
Context A few years after I created the Elastic Binary Trees (ebtree) , I started to get some feedback from users who needed to use the...
