Deleting System32\curl.exe
Let me tell you a story about how Windows users are deleting files from their installation and as a consequence end up in tears. Background The real and actual curl tool has been shipped as part of Windows 10 and Windows 11 for many years already. It is called curl.exe and is located in the … Continue reading deleting…

Two types of C programmers
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…

I Wrote an Activitypub Server in OCaml: Lessons Learnt, Weekends Lost
It was way back in the summer of 2019 when I first became a member ( i.e. a Fedizen!) of the Fediverse, the distributed social network formed by various Free and Libre servers communicating using the Activitypub protocol.

Prompt engineering vs. blind prompting
"Prompt Engineering" emerged from the growth of language models to describe the process of applying prompting to effectively extract information from language models, typically for use in real-world applications.

Revisiting the Fast Inverse Square Root – Is It Still Useful?
In 2005, id Software released the source code for their 1999 game Quake III Arena under the GPL-2 license. In the file code/game/q_math.c , there is a function for calculating the reciprocal square root of a number which at first glance seems to use a very peculiar algorithm:

Current issues with the Qt project from the outside looking in
I want to start with that Qt is still IMHO the best way to develop C++ apps. This post is not supposed to be a rant. This is for the decision maker at Qt. If you have any question about Qt feel free to join our /r/QtFramework subreddit! The Qt developers are wonderful to work with, and every new Qt version makes it…

Building a ChatGPT-enhanced Python REPL
In this blog I share my experience in building a Python REPL augmented with ChatGPT. I explore how the application is built, and speculate on software engineering patterns and paradigms that might emerge in systems built on Large Language Models (LLMs). GEPL - Generate, Evaluate, Print, Loop Link to this section…

Don't write clean code, write CRISP code
“Clean code” is so over: all the cool kids are switching to CRISP code . I’ll show you how to achieve it in five catchy, T-shirt-friendly slogans.

The New XOR Problem
In 1969, Marvin Minsky and Seymour Papert published Perceptrons: An Introduction to Computational Geometry. In it, they showed that a single-layer perceptron cannot compute the XOR function. The main argument relies on linear separability: Perceptrons are linear classifiers, which essentially means drawing a line to…

Nibbles of Rust – Restructuring Patterns
In Rust, there is this feature known as “pattern matching”, whereby you can take apart a piece of structured data by writing out patterns which bind to parts of it. This process is known as “destructuring”, because you’re breaking a structure into parts.

Algebraic graph calculus (2021)
We describe a graph-theoretic analogue of vector calculus. The linear operators of vector calculus (gradient, divergence, laplacian) correspond to the matrices naturally associated to graphs (incidence matrix, adjacency matrix). This analogy is useful for formalizing the discretization of some problems in image and…
