DiThi

We need to worry more about LEO. Orbits decay automatically, but less and less the higher you go while still within LEO. There are many polar launches which makes debris come potentially from any direction, while in GEO all satellites go in roughly the same direction.

Much lower than planes nowadays*

Obviously planes in the future can use cleaner propellants too.

It will eventually be very low, much lower than planes. The same technology that is being developed to make propellant on Mars can be used on Earth to extract CO2 from the air and/or sea water. A few squared km of solar panels on floating structures can produce enough propellant for one BFR trip a day.

The same propellant (methane) can also be used on planes, eventually, so BFR will bring many technologies advances independently of the outcome of the project.

That's true when you have more than the ratio between two things. But IMHO just a ratio or percentage is perfectly fine.

Let me put "ports" with quotes. I've played the Windows version of DOOM (2016) in Linux with same performance and didn't do anything special other than copying the configuration that had Vulkan enabled. I can imagine devs just enabling a checkbox in Steamworks to deploy to Linux automatically using Wine.

That situation will probably change as soon as most games ship with Vulkan: Even if devs devote zero effort to porting to Linux, Vulkan makes it easy to run them with Wine with pretty much the same performance. I can imagine Valve adding Wine automatically with Steam.

It's using setInterval on purpose, because with requestAnimationFrame the effect is a bit too fast.

To avoid monsters, one torch covers a radius of about 7 or 8 blocks (in Manhattan distance). But judging by that bedroom screenshot, he's being really overboard.

Damn it! That explains there are no action shots or anything...

I hope it exists one day... How would it work?

The "experiment" is _how_ head tracking is used, not head tracking itself. I agree it's not exactly new, but nobody bothered to make it for the iPhone X until now.
