Why do they keep torturing us with promises of a quantum computer? It's downright sadistic.
Hear, hear - kudos to the author. It's a massively complex subject and this is yet another baby step, and as such was heroically described.
Launch costs will have to come down below $200/Kg for this to be viable.
Thinking Big Picture like this will generate new industries that are of direct benefit to all of us.
In the meantime, aneutronic fusion is a desirable near-future goal - perhaps Focus Fusion will win the day.
Well, first of all to that despicable little NSA shit - go boil your head.
These people have lost touch with reality. I wouldn't normally be concerned, except that they are doing it on our tax dollars to the tune of billions, and are seemingly immune from being axed as an institution. Where are the politicians with the balls to toss the NSA on the garbage heap? We did fine without them before. NASA or the health care system could use that money.
The thesis of this idiot appears to be that if there's data that they cannot snoop, then it's a terrorist network. That way lies a 1984 society. It is a price most of us are unwilling to pay.
A web of solar-powered lasers for lightsail propulsion would be good. Crisscrossing the solar system. First Moon <-> Earth and then Mars <-> Earth. Can be pretty fast, and you don't need to carry tons of fuel, so you accelerate faster.
The elephant in the room is the inescapable fact, true for all propellantless drive ideas, that it is not only a perpetual motion machine, but that it can be made to generate free energy forever. This can be seen using very basic school physics. Constant input power generates constant thrust (it is claimed) and thus we get constant acceleration. Thus total input energy increases linearly with time, but output (kinetic) energy increases quadratically with time. It should now be clear that if you put this device on a wheel, there exists a breakeven speed above which free energy can be continuously obtained.
Therefore Shawyer is talking out of his arse when he says that the stored energy drops as the machine goes faster. Physics demands there be no preferred frame of reference, so pray tell, Roger old chap, how the cavity knows its velocity relative to its original rest frame?
I believe the thrust measurement is an artifact of induced patch charges. The only way to truly settle the debate is to do a space-based test.
If the Germans were serious, they'd toss out the American military bases. I know the people don't want them.
Iff a > b also
I get the LSD bit...
The sun uses nuclear fusion and puts out 10^26 watts continuously. Just a hint.
Phil Plait of Bad Astronomy fame has posted an animated gif of the left and right NAVCAM views, showing that it's in one and not the other. Normally that would be the end of the argument, but not necessarily in this case. That's because we're looking at irregular terrain and the occlusion details differ between left and right cameras.
There's also the issue of simultaneity between the two cameras; then the left camera showing nothing would mean that the flash only began in time for the right camera to grab it.
Either or both of these caveats argue for Curiosity to live up to her name, and to get the hell over there and check it out. But this is NASA, so they won't.
I wouldn't put it past Microshaft to deliberately leak something damaging to XP into the wild.
Coz it surfed on FTL spacetime. Whheeeeeeeeeee!
OK - now we know that FTL spacetime expansion is real, it's time to roll our sleeves up and build that space drive!
Pass the hacksaw, Mabel...and careful with that axe, Eugene.
And this is why moonshine can be dangerous
What if there's nothing there except turtles all the way down...
A way overpaid pompous arse, that Standen. Boot him out.
Could a new video standard, superior to HEVC, be in the offing? If so, I'll work on it.
The NSA have demonstrated beyond any shadow of a doubt that they are incapable of safeguarding the national trust - not to mention international good will. They should be disbanded forthwith. We did without them before. Accountability is a tenet of democratic government, and they spit on the idea.
Rockets are so 1950s, someone said recently - and that's true. The going rate for launch-to-LEO is between $8K/Kg and $15K/Kg - say $12K/Kg average. The sad fact is that right now we have the tech to reduce that figure to less than $5/Kg and launch multiple times per day without destroying any hardware in the process. It's called a railgun, and for my money, it's the only worthy game in town. The ideal location is equatorial and uses a few Km of track for gee-hardened cargo launches, or over 100 Km for more sedate passenger launches. The US Airforce and Navy have been messing with this, but they are really only interested in making ballistic weapons, so they use insane energy densities - about 100x more than a commercial launch outfit needs. The principle is sound, and lacks only investment. Ecuador is a good spot - there are flat stretches leading to useful mountains to angle the launch correctly.
Too late. NSA hacked Americium-241 a decade ago. They found a backdoor into the weak force.
There's a ton of bollocks in that article. For one thing, in a lot less than a million years from now we'll be able to incrementally bump out Earth's orbit as far as we like. Or two hundred million? Makes no difference. That resets the clock to 6 billion years. Everyone relax :).
But there's something else. Neglecting other catastrophes, an entire galaxy is headed our way at breakneck speed - Andromeda. ETA estimated at around 4 billion years
We may need to get galactic before then.
I read the report and think that it has a good chance of success. It certainly puts the state-approved scheme to absolute shame, being cheaper to build (10x), faster (5x), cheaper ticket price (5x), safer, more energy-efficient, less environmentally demanding, quicker to build and quicker to board. I hope there are sufficient red faces in Sacramento this week (assuming that politicians are capable of experiencing shame) to kick them into action on scrapping that boondoggle they recently approved, which would end up costing not $68B, but more likely over $100B.
The aerodynamic control and the thermal issues may be problematic, but I see no technical showstoppers here. So let's get this show on the road!
Americans should petition their congresscritters to disband the NSA
What can evolve in a billion years? On Earth, quite a lot. On Mars, maybe more.
I've been using a Logitech Trackman Marble for what seems like well over a decade, and don't want to switch. The thumb is the strongest digit, so natural for movement. It fits to the hand perfectly. And no scraping over a surface either - I detest scrapies.
Looks like the way forward is HEVC-DASH for mobile and thus for everything else.
The Chinese tried to counter H.264 (AVC) licensing with their own "AVS", which was basically a clone (what a surprise), and it fell on its arse. Earlier, Microsoft had tried the same thing with their own "VC-1" (also almost a clone) which fell on its arse. VP8 did too, as the article says. I therefore predict that VC-2, AVS2 and VP9 will all fall on their arses.
I would say a little chat with their mullah is called for here.

Like the Black Knight, I leap into the road and block your path leading to an attempt to confuse the Latin roots "before" (ante) and "opposite" (anti). You're not sneaking that one by us.
Suddenly I'm back in the nineties in the early days of UseNet (sci.physics) with the Finn Hannu P, his amazing Space Potato and his little daughter who drew cosmic truths.
Apparently the guy is still going.
Mutations - you forgot mutations. They need to be enormous and with those larger brains, group consciousness emerges and they all do something radical - like run for president or starting a company.
KISS is my creed. That's why I prefer to open docs with WordPad rather than Word, detesting bloat and incomprehensible icon blizzards as I do. Same with email - for years, having had to leave my dear old Eudora (what a gal) - I've used Outlook Express and POP'd all my email accounts down into that. I like to have my email stored locally so it can't be lost, spindled, mutilated or distributed. I've had a Hotmail addy since the nineties, but because of the horrendous spam exposure I experienced, this got relegated to the junk exposure category, and remains my email slut up to the present day.
American logic: learning to shoot things is cheaper than providing its citizenry with health care.
Yes - also it's unclear what degree of control the programmer has over CPU/GPU usage decisions. It would be nice to specify that compute-intensive inner loops be executed mandatorily on the GPU, for example. I get the impression that the GPU is auto-assigned only when the CPU runs out of puff, but that's just a SWAG.
I see Space.com is getting all snotty about this. That puritan streak still beats strong in every Yank heart.
It would be really boring without something worthwhile to do. So they need basic tools to build more stuff, like bulldozers, 3D printers, the ability to craft electronics and bowls etc themselves.
But if a bunch of hairdressers are sent, nothing will happen - Golgafrincham disease. "Have you seen my rubber ducky, Number Two?" and "We've decided to revalue the sand"
That's 7.4 * 10^7 W/m^3, about 10x the best Li-ion batteries (1500 W/Kg, 5 gm/cc)

The maximum advance time on us for another civilisation in this galaxy is around 9,000,000,000 years (9 BY) . The maths is pretty simple: the Milky Way is 13.2 BY old (close to the age of the universe), and the time to evolve from scratch is about 4 BY for our system. 13-4 = 9.
Beautiful but deadly. She's on a full-on collision course with The Milky Way, ETA 1 BY or so. Expect future classroom drills which include the injunction "Duck!". I guess we could start practicing right now...
All your base, your base, are belong to us.
Can't be iconoclastic without icons in the first place. So long live the icons and the shibboleths. Know what I mean?

I'm in San Jose California and I get 44 Mbps down and 6 Mbps up with Comcast cable. Along with the mandatory basic TV it runs me about $80 (50 quid)
8080? - pshaw. Around the same time GE MicroElectronics up in Bonny Scotland came out with the CP1600. Yeah, 16 bits in 1974. Stomped all over the 8086, but their marketing department must, in retrospect, have sucked mightily. I wonder who that was? Probably William McGonagle. He was writing poems instead of selling it.
Ah saw a CPU up on a hill
It's no there noo...
It's still no there noo.
Man has been cutting the cheese for even longer.
Word on the street is that he's been hacking his own telomeres.
