There’s a trend I’ve noticed over the the years, having seen so many companies and products fall in and out of favor with the general public. It explains why there’s such a negative view on so-called “updates” that are supposed to make the… ## [Recap - 2025](https://zerolimits.dev/blog/recap-2025) _2025-12-26 · The Blog of Random_ Last year’s Textack Merry Christmas! Or happy Christmas, as I’ve just found out some people say that instead. Yet another year has whizzed on by, and so much has happened around the world in this time. Some good things, way too many bad things, the whole deal. But Recap (yes, it’s a new name I’m trying out) isn’t about that, it’s about me, and the stuff I’ve been using! Hardware I’ve still got the… ## [Floats](https://zerolimits.dev/blog/floats) _2025-11-27 · The Blog of Random_ Long story short, I got really bored over the summer and made a new floating point format. Before we get into that, let’s dive a little deeper into how computers store data to understand what I’m even talking about here. How computers store data As I’m sure you probably know by now, computers can only read and write 0s and 1s, in a format known as “binary”. In fact, that’s what a “bit” is, a “ b… ## [Random Numbers](https://zerolimits.dev/blog/random-numbers) _2025-07-23 · The Blog of Random_ Every day I’m shufflin’ Spotify launched in 2010 with a feature to let you shuffle your songs, allowing you to play them in a random order. This used an algorithm called the Fisher-Yates shuffle . The modern version of the Fisher-Yates shuffle works as follows: Start from the last element of the array (index n-1) Generate a random index j between 0 and i (inclusive) Swap the elements at positions… ## [Finding vulnerabilities in Secton](https://zerolimits.dev/blog/secton) _2025-06-26 · The Blog of Random_ ## [Po-Shen Loh Quadratic Method](https://zerolimits.dev/blog/po-shen-loh) _2025-04-12 · The Blog of Random_ I found out about the Po-Shen Loh method of solving quadratic equations a few years ago, and I’ve been meaning to write a post about it since, and only just got around to it. You can read the original blog post by Dr Loh, which goes into the math behind the method. I’ll cover some of that math here too, as well as a code implementation of the method. Method Say we start with a quadratic equation:… ## [My takes on AI](https://zerolimits.dev/blog/my-takes-on-ai) _2025-02-01 · The Blog of Random_ There’s been a lot happening in the AI world recently. There’s a new model, DeepSeek R1, that’s just come out that everyone’s going crazy over, because it performs better than GPT o1 and Claude 3.5 while being significantly cheaper and, more importantly, open source. Of course, before this, all the hype was about GPT o1, and Claude before that. I’ve mostly taken a backseat to all of this, though I…
