Just a small correction: I don't think anyone pays for UE nowadays. Epic used to charge a monthly fee, but they've done away with that. Now you only pay royalties if your game is commercially successful. Which is different from paying for the engine itself.
Additionally, they mention that you can still negotiate paying an out right fee to license the engine if you'd like to do that rather than pay royalties (though I suspect it's mostly AAA studios that are interested in this)
It's for AAA studios because for past versions of engine cost was something like 1 mio per project. There was several more like indie developers that has won license on contests, but it's just exceptions.
> The worms converted about half of the Styrofoam into carbon dioxide, as they would with any food source.
I'm certainly not a chemist, but given that polystyrene is equal parts carbon and hydrogen (C8H8) and that carbon is roughly 12 times heavier than hydrogen I'd say that if the worms managed to convert only half of the polystyrene (by weight) into CO2 that looks much better than burning it, which -if done properly- would have converted all of the carbon into CO2.
However, I don't know how much energy can be harvested from burning it, and how to take that into account in order to decide whether it's better to burn it or to degrade it with the worms.
SoftICE was the tool that really got me into programming. Before that I was coding in Visual Basic, and tried and failed several times to teach myself C++. The books that I got where all talking about things like inheritance, polymorphism and Microsoft's MFC and none of that made sense to me. Then I found SoftICE and learned how to crack sharewares and eventually found an amazing tutorial on how to write Windows apps in assembly using MASM and calling the Win32 API directly. I used SoftICE as a debugger and it was amazing to see my code being run by the processor, instruction by instruction. I had a feeling of having a complete understanding of the computer. From there, I was able to work my way up the abstraction chain.
I use Dashlane and stopped entering credit card and billing info manually 2 years ago :-)
Their tech is amazing. They autodetect credit card fields when you focus on them and show a little popover where you can choose the card that you want to use. Just click on the card and everything fills up.

I use that here... The fact that it is needed at all is already a failure of the OS.
And the Desktop app itself is sort of unstable, and classic shell is also sort of unstable, the combination result in lots of crashes, specially if you are having issues while trying to play some games (example: on my machine every time I scroll the map too much in Arcanum from Troika Games, it crashes, crashes the desktop, crashes the classic shell, and the mouse stops working completely... it is really amazing, it crashes so hard I am impressed instead of frustated).
> And (once again, correct me if I'm wrong), the options themselves were purchased before the information was made public
No, according to the article, the options were purchased one second after the information first became public in some news wire headline. The fact that it was also 19 second before a journalist's tweet was apparently irrelevant, since there was that headline before the tweet.
It seems to me that the information leading to the journo's tweet probably also preceded the news wire headline. I guess it's _possible_ the the tweet we written by somebody who saw the news wire headline as it hit the web, and they read it, understood it's importance, wrote and posted their tweet – all within 19 seconds (not _impossible_), but I'd be curious to know where the information for the news wire post came from. Somebody knew long enough before that headline got onto the web to have time to write it (and the article).
I guess that's because the author is trying to make an player-editable world, and 3D fractals don't mix well with that.
It's actually quite hard to use 3D fractals in games (or any interactive application), unless you bake them to voxels or 3d meshes, but then you loose the infinite amount of detail that make fractals so interesting in the first place.
The rendering techniques used by 3d fractals are very GPU consuming and you can't really "edit" the world. But if anyone has been working on that, I'd be interested to see what they came up with.
Yes, but only use fractals for initial geometry, just to get some structure and then reduce the complexity and imposing a lower limit on the recursive cell size. The routine would be run once at level creation and then the geometry would optimized.
I disagree about fractals losing all their interestingness when they aren't zoomable. There's still a slew of visual complexity. Maybe they wouldn't be as interesting, but they are oodles more interesting than spheres.
Oh no, this kind of grammatical errors show that it's clearly a native French speaker. We French suck at our own language - partly because it is fairly complicated, and partly because people don't bother learning.
Thank you. TIL, actually not learned realized, space is actually a good insulator out of earth conditions too. Prejudices. We can never know what if something we thing is a reality or prejudice. Science and skepticism is that important.
Also of note is that while a vacuum doesn't necessarily have a temperature (it's just a medium), space does.
Even if you go far away from anything else, you will still reach thermal equilibrium at the Cosmic microwave background (CMB) temperature, which is 2.7K -- it's essentially the "temperature of the universe", radiation which has been emitted as far back as the first moments of the universe.
And of course, if you create a vacuum chamber on Earth, any object inside will always reach equilibrium at ambient temperature (in the lack of any heat engines on the body -- even then the fuel would deplete some time).
Technically interplanetary space is a hot plasma too. The particles emitted by the Sun are very hot according to kinetic theory (which only depends on the mean velocity of particles) since they have a lot of energy. It's a plasma because the particles are charged and accelerated by the Sun's magnetic field.
Of course the density of these particles is very low, so if your definition of heat factors those in then space is cold.
My understanding is that the spacecraft was designed to radiate large amounts of heat, with the expectation that systems inside the spacecraft would be producing a lot of it. Apollo 13 shut down much of the equipment inside the spacecraft, which meant that it was no longer producing as much heat as was expected.
A heat engine is great when your cold sink is 'free', but here, the cold sink would be the radiator fins, and extracting energy from the temperature difference between main ISS and radiator fins would effectively just make the radiator fins worse at cooling the ISS.
Which is fine if you have lots of excess radiator fins. But they almost certainly don't -- shipping up extra radiator fins in order to get power from the excess cooling capacity would be less efficient than just adding solar cells (efficiency of a heat engine maxes out at 1 - (T_cold / T_hot)).
These radiators exist specifically to deal with power which has already been used. As stated in the article, the station needs a few kW of electrical power. Eventually all this power ends up as a waste heat energy. There is nothing that can be done with it, so it has to be dumped into space.
Hmm. That made me wonder about Apollo 13, where the "crew endured temperatures at or below freezing for the bulk of the return flight" , apparently  because they had to turn off heaters and electronic gear to conserve power.
The fact they had heaters suggests that the roll wasn't so much to dump heat as to spread it around, to reduce the risk of structural damage from differential heating . That's presumably less viable on a big structure like the ISS.
Space is pretty much a perfect storm. As if relying only on radiating heat were not enough, you need gravity (or some acceleration) for convection to work. And then simply pumping a fluid through tubes is an interesting issue when the fluid does not know which way is down.
