In the 1950s, computers did not really interoperate. ARPANET has not yet happened (that would become a thing in the 60s), and every operating system was typically tied to the hardware that was meant to run on. Most communication actually happened over telephone, and no company was more present in that space than the…
It's common knowledge that Rust code is slow to compile. But I have a strong gut feeling that most Rust code out there compiles much slower than it could.
Picture this: Toward the end of the development cycle, your game crawls, but you don’t see any obvious hotspots in the profiler. The culprit? Random memory access patterns and constant cache misses. In an attempt to improve performance, you try to parallelize parts of the code, but it takes heroic efforts, and, in the…
A while ago Jeff and I had Eric Sink on the Stack Overflow Podcast, and we were yammering on about version control, especially the trendy new distributed version control systems, like Mercurial and…
Update 7 May 2022: A followup to this post containing significant conceptual advance is Xilem: an architecture for UI in Rust. I consider the Crochet experiment to be mostly negative, as there were a number of ergonomic and functional “paper cuts,” though several of the research goals were met, at least to some extent.
Syntax highlighters make value judgments about code. Most highlighters judge that comments are cruft, and try to hide them. Most diff viewers judge that code deletions are bad.
js;dr = JavaScript required; Didn’t Read. Pages that are empty without JS: dead to history (archive-org), unreliable for search results (despite any search engine claims of JS support, check it yourself), and thus ignorable. No need to waste time reading or responding. Also known as, if it’s not curlable, it’s not on…
Probablistic filters are high-speed, space-efficient data structures that support set-membership tests with a one-sided error. These filters can claim that a given entry is definitely not represented in a set of entries, or might be represented in the set. That is, negative responses are conclusive, whereas positive…
While reading Hacker News posts about JavaScript, I often come across the misconception that Ruby's blocks are essentially equivalent to JavaScript's "first class functions". Because the ability to pass functions around, especially when you can create them anonymously, is extremely powerful, the fact that both…
Before we dive into the technical details, let’s start with a quick history lesson, courtesy of Don Syme who worked on adding generics to .NET and then went on to design and implement F#, which is a pretty impressive set of achievements!!
A while ago, I bought the book “ The Go Programming Language ” written by Alan Donovan and Brian Kernighan. I have always been a fan of Brian Kernighan’s writings. I should admit that I bought the book mainly for his great examples and writings than for the Go language itself, but since then have got interested in the…
I’ve seen people be genuinely puzzled about why functional programming is not more popular. For example I’m currently reading “Out of the Tar Pit” where after arguing for fu…
Popular programming languages provide methods or functions which locate a substring in a given string. In C it is the function strstr , the C++ class std::string has the method find , Python's string has methods pos and index , and so on, so forth. All these APIs were designed for one-shot searches . During past…
Rust's error handling is a pleasure to use thanks to the Result type . It ensures Rust's error handling is always correct , visible , and performant . And with the addition of the ? operator in Rust 1.13 , and the addition of return types from main in Rust 1.26 Rust's error handling has only kept improving.
Earlier this week, Haroen Viaene posted this tweet about YAML: worst part of yaml: https://yaml.org/type/bool.html — Haroen Viaene (@haroenv) January 10, 2022 The linked-to page contains the documentation on what defines a boolean in YAML, and details that it can be parsed using this regex…
This post is about the magic constant 0x5f3759df and an extremely neat hack, fast inverse square root, which is where the constant comes from.
K/V context cache quantisation has been added to Ollama. This enables significant reductions in VRAM usage, allowing users to realise the potential of expanded context sizes and run larger models at their existing context sizes.
Jan Gampe took things to the next level by actually making this cross-stitch out of the pattern I previously posted online. The flowers really gave it an extra level of charm I think. As a cross-stitch As a pillow This quote is from a comment by an upset user on my blog, replying to one … Continue reading curl is just…
I graduated with a Computer Science minor from the University of Virginia in 1992. The reason it’s a minor and not a major is because to major in CS at UVa you had to go through the Engineering School, and I was absolutely not cut out for that kind
During my recent trip to Vietnam I took the opportunity to visit some schools and see how computer science was taught there. Officially, foreigners require permission from the department of education to enter schools. But it's much simpler (and the results are more representative) to simply show up unannounced. A…
People in the programming language design community strive to make their languages more expressive, with a strong type system, mainly to increase ergonomics by avoiding code duplication in final software; however, the more expressive their languages become, the more abruptly duplication penetrates the language itself.
Introducing Ezno and the current state of the project.
This post is about writing technical documentation. More specifically: it's about writing documentation for programming languages and libraries.
LMAX is a retail financial trading system that can handle that can 6 million orders per second on a single JVM thread. The business logic runs in-memory surrounded by disruptors using event sourcing.

The microservices architecture can be useful, but to know if it's suitable in your context you need to understand its costs and benefits.
