I've written simulators as a career for more than a decade, and I'm stunned at what a good job you've done. The simulation engine is excellent and the visualization is prettier (and more intuitive!) than any I've ever se

Growing up in Cincinnati, the Omnimax at the museum center was a huge influence. The light tunnel intro (one of many adapted from the Graphic Films Corporation logo [1]) absolutely blew my mind and gave me a lifelong obsession with computer

This appears to be by Kenta Cho, a.k.a. ABA games, who has a long history of writing wonderful small games in D. His work is well worth checking out. https://www.asahi-net.or.jp/~cs8k-cyu/

Power conversion losses account for about 60% of the energy that goes into electricity generation in the US [1]. Superconducting generators and transformers could take that figure down to a fraction of that. [1] https://www.eia.g

These algorithms work best on smooth functions with mid-to-low 100's of variables. They are very sample efficient, often obtaining superlinear convergence using just a linear number of evaluations of the objective function.

I'm very glad to see these algorithms get the maintenance they deserve. I pulled them apart and used lots of their pieces and theory for my PhD; MJD Powell's original code was subtle and difficult to understand. Hats off to those

You raise a very good point in that the "formulate the problem the way the solver wants" step is legitimately difficult and full of pitfalls. Simply figuring out the translation can be hard, and even then there are many ways to fo

Both companies are huge and contain multitudes; they can easily do praise-worthy and scorn-worthy things at the same time. It's worth calling them out separately rather than trying to unilaterally love or hate the whole mess at once. T

> Is it? Some of my friends went on to start successful companies after getting their PhDs. I'm a bit envious of them actually, I didn't have that option as my research was on an obscure topic with zero commercial potential. Ag

You're correct, autonomous vehicles are absolutely not to the point where highway robbery is a prime concern. But even if they were, the spoofing issue isn't just another tough problem to solve. It's a potential arms race.

I competed in the DARPA Urban Challenge, back in 2007. While we were watching the finalists trying to sort out the world's first fully-automated traffic jam, the conversation turned to how easy it is to manipulate these vehicles. Imag
