std::flip is a little-known utility from the C++ standard library header <functional>: it is a higher-order function that accepts a Callable and returns an equivalent Callable with the order of its parameters reversed (or “flipped”).
C++ seems to finally converge with their contracts proposal, I decided to give it a try and come up with ideas how such a thing would look for C. This is in early stages, not a full proposal yet, a…
Vim is a powerful text editor that improves coding speed & efficiency through its shortcut-based Vim language. While learning Vim can be challenging, it is a valuable skill that can enhance your career as a computer professional.
There are very few universal rules in software engineering, but there are are a lot of near-universal principles. Things like "prefer composition to...
A deep dive into Google Translate (and other browser extensions) interference breaking React and other web apps.
Scaling reinforcement learning, tracing circuits, and the path to fully autonomous agents
Sometimes a merge request (MR) doesn't merit a code review (CR) because AI was used in a bad way that harms the team or the project. For example:
I find myself writing yet another toy parser, as one does during a Christmas break. It roughly follows Resilient LL Parsing Tutorial. Not because I need resilience, but mostly because I find producing a syntax tree and a collection of diagnostics a more natural fit for the problem than bailing out on the first error.
In the previous chapter, we assumed that we can uniformly randomly sample our domain. However, it’s not obvious how to actually do so—in fact, how can a deterministic computer even generate random numbers? 1
Fantasy consoles like the Pico-8 are a great idea. A fantasy console provides a standardised and portable environment in which developers can explore ideas within creative constraints. The Z-machine , developed by Infocom in 1979, is the earliest fantasy console I know, although this is probably the first time it’s…
A few months ago, I decided that it’s time I started to become more responsible and to start drinking more water. Unfortunately, the tap water where I live has a very high calcium content, which makes it a lot better when filtered and cooled first. To solve both issues, I picked up a second-hand professional water…

Karl Seguin's Blog - A mix of coding and creative writing
Introduction In this blog post you are going to read about two things:
To denote the subsequence of natural numbers 2, 3, ..., 12 without the pernicious three dots, four conventions are open to us
Because I'm a massive nerd, I actually try to read specification documents. As I've ranted ad nauseam before, the current TOTP spec is irresponsibly obsolete. The three major implementations of the spec - Google, Apple, and Yubico - all subtly disagree on how it should be implemented. Every other MFA app has their own…

The number of characters was 464 characters at first, but thanks to the community it got reduced further, and the article updated accordingly.
Notes on using the Z3 constraint solver with the Clang Static Analyzer
The craft of programming is almost universally concerned with different types of data and operations/algorithms that act on this data [1] . Therefore, it's hardly surprising that designing abstractions for data types and operations has been on the mind of software engineers and programming-language designers since…
Half a century ago, the puzzling phrase "special register groups" started showing up in definitions of "CPU", and it is still there. In this...
Concept Motivation Imagine an open world RPG where your actions affect the price of goods, the markets reacting to anything the player may do (burn down wheat fields, cost of food increases; kill the merchants, prices differentiate between cities; sell the many swords you’ve collected on your adventures, tank the…

Reverse Engineering Reality
This is a post about multiplying polynomials, convolution sums and the connection between them.
First part of a series of articles about writing a .NET Garbage Collector in C# using NativeAOT. This part sets the expectations and setups the project, dealing with the first difficulties.
Last summer, I published Raven , an independent implementation of the Uxn CPU and Varavara ordinator . In short, this is a fictional computer designed for cross-platform portability: programs targetting it can be run on any platform that implements the specification.
