Simulating and Visualising the Central Limit Theorem

Simulating and Visualising the Central Limit Theorem Categories: Statistics R 34 minutes read I completed a Computer Science degree at uni, and bundled a lot of maths subjects in as electives: partial differential equations, vector calculus, discrete maths, linear algebra. For some reason however I always avoided statistics subjects. Maybe there’s a story to be told about a young person finding uncertainty uncomfortable, because twenty years later I find statistics, particularly the Bayesia

I made a real-time C/C++/Rust build visualizer

August 13, 2025・6 minute read Many software projects take a long time to compile. Sometimes that’s just due to the sheer amount of code, like in the LLVM project. But often a build is slower than it should be for dumb, fixable reasons. I’ve had the suspicion that most builds are doing dumb stuff, but I had no way to see it. So I’ve been working on a cross-platform tool to help speed up builds (you can try it, see below). It works with any build system or programming language (Not just C/C++).

Gerard Butler's Movies Tend to Fly Under the Radar in Theaters, but They're Living It Up in Netflix's Top 10

Each week, Netflix drops a list of the top 10 films and TV shows dominating the platform, and for the week of Aug. 4, two Gerard Butler films appear in the US Top 10 list: 2016's Gods of Egypt and 2023's Kandahar. Butler is a reliable movie star whose career is filled with action and adventure films (and the kid-friendly How to Train Your Dragon franchise), but I didn't realize that his name carried so much weight -- and that he was this prolific -- until I noticed he stars in six films currentl

Google Wallet has a new shortcut UI, but I’m not sure it’s an upgrade

TL;DR Google Wallet has gained a new UI when you activate it via a double-tap of the power button. This UI features a transparent design and an animation showing you how to tap your phone. Unfortunately, this UI change means you can no longer launch the full app with a double-tap. Android 16 on Pixel phones lets you double-tap the power button to activate Google Wallet. That’s a welcome change as the gesture was previously restricted to launching the camera. Now, a new UI is rolling out for t

Google Searches for 'Taylor Swift' Summon This Dazzling Easter Egg

What are Apple’s options for an AI acquisition beyond Perplexity?

Since Apple’s latest earnings call, talk of a potential Perplexity acquisition has quieted down (the fact that Perplexity was once again allegedly caught red-handed sidestepping content restrictions didn’t help). Meanwhile, with the ever-increasing number of engineers from its Foundation Models team jumping ship, Apple’s need for fresh talent is getting more urgent by the day. But if Perplexity is a no-go, who else could Apple buy? I used to agree with Jason Snell’s frequent argument on the Up

It Might Already Be Too Late to Save NASA

One of president Donald Trump's long-held desires has been to replace NASA with private spaceflight enterprises.
