Have the rockets gone to orbit already?

What is the advantage of that over just big solar fields in space, and does it make the transport problem any less onerous than space based solar power?

I’ll be doing a talk Saturday (2/1) at the Frontiers of Flight Museum in Dallas from 5-7 pm on STEM fields. Stop by if you are in the area!

But they are a fraction of the throw of the current controllers. Mimicking the feel of professional equipment is a good plan, though!

Changing this now would probably be too traumatic, but I tend to think that VR controllers would be better with a crisp, binary trigger instead of a squishy analog one. Games like Audica and Pistol Whip would be objectively improved. Sound off if you would hate that.

I am still planning on being at Oculus Connect unless something changes, although probably not giving a keynote.

It is never going back to a single CPU, but I do sort of dream of replacing everything else with just lots of symmetric cores, so a single development environment and codebase ran everything, instead of a dozen quirky enclaves.

Unfortunately, it is probably going to continue getting worse due to the realities of silicon performance. In addition to CPU and GPU, we now have DSP, video codec, and now neural processing accelerators coming along on mobile.

I definitely favored 360 over PS3 development — more symmetric CPU was better than CPU + cell from a simplicity standpoint. You can take the argument all the way back to GPUs — we have sort of forgotten how nice just drawing pixels with the CPU was...

I’m not sure it was a good idea. I was of the opinion that the best consoles were one good CPU and one good GPU, on the lines of the PS1, Dreamcast, and original XBOX. Still, games do nicely decompose into at least game/render threads, so the value prop of multi core was strong.

\ that only a handful of studios deliver the majority of the value, then it would be the correct decision. If a broad set of less technical developers support the ecosystem, it would be wrong.

Console vendors made conscious decisions to produce challenging hardware that would let high end developers get higher performance, even though it would be worse for the majority of potential developers. If you think that having the single most impressive title is critical, or \

Never heard of it. I had never seen an Amiga at that point; I was aware that they were supposed to have awesome games, but I didn't know anyone that had one.

I was puzzled by this (reading about SPSA):
"uniform and normal distributions do not satisfy the critical finite inverse moment condition"
Later, I figured out that it was just because they would cause divide-by-zero problems, unlike the strictly -1/1 Bernoulli distribution.

Yes, you could do that, but it would be really nauseating until you got used to it, at which point the real world would then be nauseating.

That can’t be done with software, it has to be done in the optics.

I am very often tempted to work on a small or retro project, but the odds of going back into AAA are near-zero.
