The new supercomputer behind the US nuclear arsenal
In 2018, 100% of supercomputers run Linux.
actually you'll have to go back more than 10 years to see even slight share of other OSs :

The Most Costly Joke in History
Quite a lot of nations have old soviet Shilka's which do those supercomputer calculations. https://www.youtube.com/watch?v=N-UnealTR-Y
You get within 1.5 miles of this thing, and it chews up anything that isn't jinking.
There are also variants of this thing which have missiles, and they can even shoot down other missiles to protect itself.
For those it's better to fire helicopter missiles from a low angle. Or bomb them from up very high.
Helicopters are less vulnerable because often they can fire without revealing their position. Modern missiles can be fired from as around 8km away. And they'll fire them while hovering low enough that their radar signatures can't be distinguished from the ground and surroundings. And since they are always facing the enemy their heat signature from the engines is facing away as well. (unlike a warthog that will show it's engines to the enemy as it flies up and away after an attack). Most attack helicopters have some kind of armour as well. At least in the pilot and critical sections.
Oh yes, and something really cool - the new Apache Longbow's can fire missiles that go around terrain to hit their targets! Super cool
They absolutely have disadvantages, but any decent pilot will fly their aircraft to it's advantages
What? Helicopters are LESS vulnerable? How do you figure? They're vulnerable to small arms fire from ground troops, unlike a Warthog (unless you have a super sniper around that can do supercomputer type calculations in a fraction of a second and hit it on the fly with a 50 cal. depleted uranium round). They can pop up and down behind cover and do awesome targeting tricks, but in my eyes, for every advantage they have, there's another disadvantage.
But then you hit the nail on the head. Drones do it ALL better, for exponentially less, without putting a highly trained pilot in danger. I think it's just plain dumb to make piloted planes when we have working drone tech. For the current cost of the R&D on this single plane, not including the cost of building a single working F-35, we could have 1.3 million drones (+-, if we make that many, I'm sure we can make them for <$1 million a piece) and own the skies of the entire planet for eternity....or at least until Skynet takes over. Drones are far cheaper to maintain, don't have the G-force limitations human pilots do, can do far more dangerous jobs because we can afford to lose them, etc. We should never make another fighter that has a pilot IMO....maybe not any kind of military fighting plane. I also love the A-10, but I've never had to fight in one. That cannon though, so satisfying.

I'm saying that the F-35 doesn't need to do the job of the A-10 in the same style, because helicopters and drones already fill that loitering style of close air support. And they fill it better than the warthog. Drones loiter better and longer, and helicopters are less vulnerable while having just as much fire power, with the ability to keep enemies suppressed without stopping to turn around and run in again. Helicopters don't even fly that much slower than the A-10 and they have the advantage of being able to stay on the friendly side of the battle-line while firing at the enemy, as well as being able to use terrain as cover.
And fast movers do a better job of delivering bombs.
The warthog was created as a soviet tank killer and hasn't been used in the role ever, since the cold war never became a hot war. It was created in a time where high losses were acceptable. You could argue it was made to fight a war that didn't happen either. But it's been upgraded with all sorts of sensors that are already in helicopters and drones to extend it's role into something it wasn't really designed for in the first place.
I'm not beating up the warthog, it's my 2nd most favourite plane. I've logged some 400+ virtual flying hours in the A-10C in DCS World. I know what every single switch does in the cockpit. And I've dropped thousands of simulated laser and GPS guided bombs, launched thousands of mavericks, and strafed thousands of BMPs. I love the thing really
But it's duties are performed better by a range of modern aircraft now.
Life-like Star Wars Battlefront Rendering
Have seen this before... it's pretty amazing, but unfortunately, it runs like a slide show on anything less than a supercomputer.
Still, good to see what could be achieved in the next few years.
Oldest working digital computer rebuilt and running programs
Interesting vid
There have been a few articles in The Register over the years as the rebuild was planned and executed:

I think it's probably worth mentioning that some of the other early British computers were interesting too:

Not only the Atlas, but J. Lyons & Co's LEO was interesting for being entirely commercial at a time when most computers were either research machines, or used by the military.

M.I.T. Computer Program Reveals Invisible Motion in Video
This reminds me of oceans 13 where they had a supercomputer monitoring a person's heart rate and facial expressions to determine if gambling wins were legitimate or not. For as good as something like this is shown, I hope it doesn't have a bad side that opens up ethical use questions.
Worldz Fastest Computer
HA!
A lawsuit for misrepresentation?
But the most important part in all supercomputers are the pretty decals they put on the front of server racks to block off proper air flow.

Smarter in Seconds: Behind the Scenes At The White House
I'd change the cabinet meeting room a bit.
~Replace seats with sensory deprivation chambers
~Replace the cabinet with the IBM Gene/Q "Mira, a 10 peta-flop supercomputer, and name it Woodrow.
~Turn the basketball court into a miniature horse arena tended by a newly-appointed staff of performers from Cirque Du Soleil

14 BILLION YEARS OF EVOLUTION IN ONE MINUTE
Boner: It is still confusing...
Astrophysicists have created the most realistic computer simulation of the universe's evolution to date, tracking activity from the Big Bang to now -- a time span of around 14 billion years -- in high resolution.
Created by a team at the Harvard-Smithsonian Centre for Astrophysics (CfA) in collaboration with researchers at the Heidelberg Institute for Theoretical Studies (HITS), the Arepo software provides detailed imagery of different galaxies in the local universe using a technique known as "moving mesh".
Unlike previous model simulators, such as the Gadget code, Arepo's hydrodynamic model replicates the gaseous formations following the Big Bang by using a virtual, flexible grid that has the capacity to move to match the motions of the gas, stars, dark matter and dark energy that make up space -- it's like a virtual model of the cosmic web, able to bend and flex to support the matter and celestial bodies that make up the universe. Old simulators instead used a more regimented, fixed, cubic grid.
"We took all the advantages of previous codes and removed the disadvantages," explained Volker Springel, the HITS astrophysicist who built the software. Springel, an expert in galaxy formation who helped build the Millennium Simulation to trace the evolution of 10 billion particles, used Harvard's Odyssey supercomputer to run the simulation. Its 1,024 processor cores allowed the team to compress 14 billion years worth of cosmic history in the space of a few months.
The results are spiral galaxies like the Milky Way and Andromeda that actually look like spiral galaxies -- not the blurred blobs depicted by previous simulators -- generated from data input that stretches as far back as the afterglow of the Big Bang, thus portraying a dramatic cosmic evolution (see the above video for a sneak peek of that evolution from four billion years after the Big Bang).
"We find that Arepo leads to significantly higher star formation rates for galaxies in massive haloes and to more extended gaseous disks in galaxies, which also feature a thinner and smoother morphology than their Gadget counterparts," the team states in a paper describing the technology.
Though the feat is impressive -- CfA astrophysicist Debora Sijacki compares the high-resolution simulation's improvement over previous models to that of the 24.5-metre aperture Giant Magellan Telescope's improvement over all telescopes -- the team aim to generate simulations of larger areas of the universe. If this is achieved, the team will have created not only the most realistic, but the biggest universe simulation ever.

this video is a waste without addition information.
what am I looking at. spiraling gas' or something.
what is the significance, why did nine people upvote something they probably do not understand.
what part of the universe is this ? why didnt it start at the beginning ?
WHY WHY FUCKING WHY.
Louis CK - What Would You Do with 85 Billion?
Sorry to be a downer, but I would try to actually accomplish something useful for mankind. Immense wealth is just a holding hostage of a huge amount of human labour; it isn't a license to squander that labour.
That said, I would be making this post on my supercomputer; sitting on a chair made of 5-6 live, nude, female gymnasts who would work four hour shifts supporting my bloated form while lovingly tonguing and caressing my balls. Bill Gates could really have that. He could have a chair made of women.
