"poor failure skills" is a great phrase!

I remember being baffled in my early 20's how people that failed at a company were more attractive for investment than people who hadn't yet tried, but that was naive.

You generally have to "do some reps" to build the necessary skills to properly execute, regardless of the actual innovation you can bring to bear.

I have always advocated cloning classic games like Space Invaders, Pac-Man, Wolfenstein 3D, etc, as an effective part of a learning strategy towards game dev mastery. I now realize that initial copycat companies can be similar for entrepreneurs.

You are probably not triple buffering the text panel image, which means it is getting updated while TimeWarp is still reading it for the screen.

Keyhole was the name of a line of spy satellites. Aperture is the area of the lens / reflector / antenna — the bigger, the better.

I got to review the first half of this book early on, before the breakdown between the author and FB comms. The things I had first hand knowledge of were accurately reported, and I learned a bunch of stuff that happened outside my view.

There is a simulator available with source somewhere (in MAME, maybe?) that I heard 3dfx old-timers say was really good.

Cost of propellant is almost never an issue for rocketry. Getting a reliable supply is a problem. FMC has pretty strict rules, and small specialty companies come and go. That alone is a strong argument to use LOX, which is cheap and easy to get.

We did one vehicle with autogenous lox / methane propulsion, but didn't fully develop it. It is especially exciting for upper stages, where you can "burn the tanks down to vacuum" if the engines can also run gas/gas.

Yes, many PC titles do use higher bit depths.

It is possible, but just doing it with the existing range of apps would make the intensity transitions in dark areas brutally obvious. It really needs higher bit depth eye buffers, which is a big performance cost.

I am hiring design leaders and designers for AR and VR teams at Facebook/Oculus. Roles in MPK, SEA and LA. My DMs are open.

Yes, it would reduce internal reflections — I suggested it years ago!

So many people to deal with, my brain is sometimes blanking on names of people I have dealt with for quite a while. Not an LRU capacity miss, so I must not have enough set associativity.

I don't remember, but probably less than that. I still have mine in one of the stand-up display cases used for an event!

I wonder what the trade offs are for piggy backing other instruments on low orbit comm sat constellations. You aren’t going to get a Keyhole aperture, but being able to have 24/7 coverage of anywhere seems valuable.

The built in everything-is-restrict should help to some degree, but a performance improvement is not the reason to reach for it.

AV1 isn’t delivering any significant compression wins? They set out to... I do think there is going to be a big jump with deep learning codecs at some point, versus all the hand coded experiments in the codec specs today.
