It was just over 10 years ago when I wrote my original blog post on WiFi. Looking back on it, it’s incredibly nerdy – did I really include a sparsity plot for a matrix? Nevertheless, it blew my mind how viral it went, along with the Android app that came shortly afterwards (written in a mad microwave-curry-and-energy-drink-dash). I therefore have it to thank for the inspiration to continue to write, safe in the knowledge that the internet was full of maths and physics geeks like me. It probably also led pretty directly to my current career writing software professionally.

As a tribute then, let’s dust off the ol’ solver and buff it up to a 2024-like shine. Hopefully the internet is just as full of geeks as it was a decade ago!

For something I dashed out pretty quickly during some medical leave from my PhD, this is all very cool. However, it never really sat right with me that the quality of the app itself was pretty poor – it was a single-screen, not responsive, slow, and increasingly out-of-date compared to the latest Android features. It nearly disappeared entirely earlier this year when I thought I’d lost the key I used to sign the upload!
