ballin#One night — after a glass of wine — I had another idea: one modern trick with ASCII art is the use of Braille unicode characters to allow for very high detail. That reminded me of ball physics simulations, so what about building a full physics simulator also in the terminal? So I asked Opus 4.5 to create a terminal physics simulator with the rapier 2D physics engine and a detailed explanation of the Braille character trick: this time Opus did better and completed it in one-shot, so I spent more time making it colorful and fun. I pessimistically thought the engine would only be able to handle a few hundred balls: instead, the Rust codebase can handle over 10,000 logical balls!
The company’s tech comes from an unusual source: a $100-million-endowed program at Caltech to develop orbital solar plants that would beam electricity to Earth below. The researchers ultimately settled on a sail-like structure that is thin and flexible compared to boxy, traditional satellites.

There’s not much to love about big tech these days. So many ills can be laid at its door: social media harms, misinformation, polarisation, mining and misuse of personal data, environmental negligence, tax avoidance, the list goes on. Added to which, Silicon Valley’s leaders seem all too keen to cosy up to the Trump administration, to shower the president with bribes – sorry, gifts – and remain silent about his worsening political overreach. And that’s before we get to the rampant “enshittification”, as the tech writer Cory Doctorow describes it, which means that by design many big tech products have become less useful and more extractive than they were when we originally signed up to them.
