The Cucconi test is a nonparametric two-sample test that compares both location and scale. It is a classic example of the family of tests that perform such a comparison simultaneously instead of combining the results of a location test and a scale test. Intuitively, such an approach should fit well unimodal distributions. Moreover, it has the potential to outperform more generic nonparametric tests that do not rely on the unimodality assu..

With the recent news of OpenAI’s web crawler respecting robots.txt and the ensuing scramble by seemingly everybody ensuring their robots.txt is blocking GPTBot, I was thinking if there wasn’t a better solution to help our future AI overlords make sense of the world. As I am hosting all my sites on a tiny NUC using nginx and having previously played with its return directive I decided to reuse the same trick for visits of GPTBo..

Someone on Discord asked about how to learn functional programming. The question and my initial tweet on the subject prompted an interesting discussion with Shriram Krishnamurthi and other folks. So here's a slightly more thought out exploration. And just for backstory sake: I spent a few years a while ago programming in Standard ML and I wrote a chunk of a Scheme implementation . I'm not an expert, but I have a bit of backgro....

Godot 4’s HTML5 export uses WebAssembly, WebGL, and SharedArrayBuffers. Browsers require a secure context for these features to be available, which requires sending certain HTTP headers when serving the game content. For development, there are two straight-forward ways to serve the content: Godot’s Python http server and Miniserve.

There’s a neat paper Type Systems as Macros by Chang, Knauth, and Greenman [ 1 ] that describes how to implement a typed language using an untyped host language and macro expansion. The paper is neat, but I found the code hard to follow—the paper uses a compact notation that’s convenient for print, but not so much for reproducing on one’s own. This post is my attempt to implement and explain in more accessible terms what’s presented in th....

Hi, Letzte Woche sind die Emotionen hochgekocht. Einer meiner Kunden hat etwas außergewöhnliches geschafft. Sie betreiben seit 10 Jahren erfolgreich ein Produkt. Höchst profitabel. Aber das Projekt wurde nicht von ausgelernten Entwicklern begonnen. Es startete als Nebenprodukt. Die ersten Entwickler waren Queereinsteiger. Super interessiert, motiviert, engagiert und Experten in der Domäne. Und ihnen ist etwas gelungen, was in 9 v..

I am curious how those justify sustaining open source or doing programming 'for fun' when you can make a profit from it instead. I have a few open source libraries that I find mildly dumb in retrospect because there's no profit to be had in maintenance (beyond my use case). The only respectable open source development is paid dev-time by companies (as it is within each company's interest to combine forces rather than maintain their own bi..

I am on Ubuntu Linux 22.04 LTS and there is filed called hello.py with content print ( "Hello world!" ) It’s basically “What happens when you do python hello.py in the terminal, on Linux ?” from the point you run the command to the point you see the o..

Lately I've been tinkering with optimizing Sasha's llama2.rs , a fast Rust port of Karpathy's llama2.c. It takes advantage of Rust nightly's portable_simd, which allows you to emit AVX2 or AVX512 instructions using a relatively clean set of abstractions, and also run inference on a quantized llama2, so it's pretty fast. One of the core loops looks like this: let mask = ( 1 << BITS ) - 1 ; // BITS is 4 let elems_p....

When we’re writing programs, we usually deal with some kind of dependencies: databases, loggers, caches, telemetry… Setting up a full-blown Dependency Injection framework could be a solution to this, but Effect has some aces in its sleeves that make DI frameworks unnecessary. Let’s see how we can manage dependencies using Effect. Intro to Effect series: What is Effect? Handling Errors Managing Dependencies Concurrency in Effect ....

Big video handlers like YouTube and even Slack use AI to automatically caption videos that you upload. This is a great win for accessibility, and the AI is extremely accurate. It sometimes stumbles on uncommon words and bad audio signals, but these can be easily fixed by a human. I think most would agree that the benefit and cost savings of generating 95% accurate captions greatly outweighs the cost of having none at all! So at work we we....

I recently got a smaller computer screen. It’s actually not that small, it’s 27", but the resolution is modest compared to what is available. And in short, it’s fantastic. It’s not an expensive screen, it’s not a fancy screen; but it’s comparatively a small screen. For a few years I was using a 34" ultra-wide monitor, which has been causing me nothing but grief. It’s sort of crept up on me that so many small annoyances in my computer-us..

This is a bit of an what I’ve been working on style of post. It’s also a bit of a complement for the release notes of the upcoming release which should be dropping in a week or so. There’s some spit and polish still missing from these things, but if I don’t write about them now too much will have been ejected from the cache to make a well written post about it.
