Anyone have any references for implementing a file format for allowing user mods?

Random rants about games that do it poorly welcomed/encouraged.

Or, you know, games that do it well.

Does anyone have suggestions for a good comprehensive resource for rigidbody physics?

(Specifically collision resolution, RTCD is enough reference for collision detection.)

Ideally looking for books / web stuff, not existing implementations to reverse engineer.

Witness the power of this fully loaded cat tree. Mew. Mew. Mew

One insight from the book I found particularly interesting so far was on the interpretation of the output values of a neural network. It turns out to be useful to consider the outputs as parameterizing a probability distribution over the "true" output, eg Gaussian, beta, or Bernoulli/multinoulli (depending on the type of output data). Then, you can use maximum likelihood estimation to automatically generate an appropriate cost function for training the NN. Cool! 🤓

I've been reading this book: deeplearningbook.org (out of personal interest). It's fascinating how totally the field has changed in the last ten years. I took a college class on neural networks and machine learning in ~2007, and it turns out, back then we were just…doing it wrong in many ways. Today's methods are more systematic, better-founded, and often *simpler* to implement than what we did in that class. (Having much larger data sets and much more computing power helps a lot too.)

C++ coders will have heard of unique_ptr and shared_ptr, but did you know about cat_ptr?

It has two states: awake and sleeping. When sleeping, it stays in one place, but when awake it random-walks over memory. An object cannot be moved or copied while the cat_ptr points to it.

Another sobering talk from Maciej Ceglowski. He's shaping up to be a good candidate for "conscience of the tech industry."

"Retpoline", an optional compiler flag to deal with Spectre attack support.google.com/faqs/answer. Landing to llvm/gcc as we speak (e.g. reviews.llvm.org/D41723).

Virtual calls, as well as switch statements etc., are about to get more expensive.

by the way, I have nothing but love for those of you who work for megacorps. people gotta work to live and I don't hold you responsible for the overall direction and activities of your corporate overlords. I like to think you're all subverting your overlords over the long-term anyway. 😘​

Ok, multi-toot rant (sorry) — I was thinking about violence in video games. It is a topic that comes up from time to time, and invariably, as someone making video games, you are asked for your opinion (or to justify your work.) So here is my opinion: 1/4
