...breaking, it's fucking BROKEN already! IDS has ADMITTED in the Select Committee inquiry that the system IS NOT READY for rollout and that it is so full of flaws that the planned completion of rollout in 2017 WILL NOT HAPPEN.
yep, Dyson actually referred to a shell of discrete segments rather than a solid sphere, Armstrong laid a (very feasible, as it goes) construction timetable. A swarm could be built using the mass of Mercury in about forty years according to that, and Venus follows (OK it's bigger and the numbers might get confusing) over the next ten.
GNU has been around since *1983*!
Linux was released in *1991*!
By 2010 the city of Munich public services had deployed SuSE Linux in 20% of its front end systems following prior announcement of the plan in 2003, with the stated intention to complete the transition to FOSS by 2015. citation
Personally, I've been using Linux in various flavours and for various projects since 1996.
So clearly, the Head of Delivery is full of shit.
not so long ago (1990, in fact), Carl Sagan persuaded the Voyager team to look back and take a photo montage of the solar system. Earth appeared as a pale blue dot, yet smaller than a single pixel. While still within the terrestrial sphere of influence in the 1970's, Voyager's instruments were turned back toward Earth, and while "some" chemical signatures were recognised (water and oxygen), the consensus was that it could not be confirmed whether there was in fact life on the planet. If we couldn't confirm life on a planet where we knew for a fact there *was* life, from a distance of less than five million miles, then what hope do you think we have of detecting anything smaller than a Jupiter-mass blob orbiting a star fifty light years away or determining what a rock orbiting Epsilon Eridani (there are two known; one at least is a gas giant about five to eight times the mass of Jupiter) is made of?
BTW, the 1936 Olympics has now been shooting in every direction through space for 77 years and change. Counting M-type cool dwarf stars, that signal has probably crossed over eight thousand star systems, and it will continue outward forever.
Dyson's original idea was to build a cloud of satellites. Stuart Armstrong expanded on this and conceived a construction timescale on the order of *less than a Century* from striking ground on Mercury to lifting the last segment from Venus to orbit.
Dyson structures have been shown elsewhere to be mechanically impractical purely due to the amount of material they'd need. A single fully enclosed, solid Dyson sphere surrounding a G2V star such as our Sun, at the outer edge of the Goldilocks zone (around 94 million miles from the centre of the star) and just nine feet thick would require the complete disassembly of all four inner planets (Mercury, Venus and Earth and Mars and all associated satellites, shepherd asteroids and Lagrangian objects), the entire asteroid belt, and all the moons of Jupiter and Saturn. The amount of energy that would be required to counter any drift during and post construction would be immense (say bye bye to Jupiter, being the second largest and ready source of hydrogen available locally), and what are you going to use for atmosphere? Our envelope wouldn't be near enough, unless you can learn to cope with 1/640millionth of a bar pressure. That's right, you'd have to completely convert the entire gas content of TWO G2V white dwarf stars (two of our SUNS!) to oxygen and nitrogen and pump it in. Which brings another couple problems: how are you going to contain a gas envelope that just wants to fall into the Sun? And having solved that problem (you have, right?), how are you going to cope with 80 miles of gas pressing out against nine feet of iron and nickel? You'll need another couple planets' worth of iron just to reinforce the sphere!
Oh yeah, and water might become a bit on the scarce side as well; the entire content of our oceans and polar caps, rivers and lakes would form a solid ice ball only 360 miles wide. That wouldn't be enough to form a ground frost on the inside of the sphere.
if the volume of the universe is infinite, it can be reasoned (I won't go into the why) that it was infinite fourteen billion years ago.
We're talking about 1GPa of pressure at 300K here. That's 10,000 bar. Or 64 miles deep, then you're talking ice at room temperature.

I don't think it would last long though (probably only a few hundred million to a couple billion years in the Goldilocks Zone), considering the surface, even though it would be frozen solid in about 6 seconds after exposure to space, would start to sublime under raw solar radiation (and be instantly whipped away in a massive ion tail turning your planet into a super-giant ice comet) and particle bombardment since there would be little, if any, magnetic field to deflect said particles and no atmosphere to absorb the radiation.
sounds more like New Delhi. The only place I know (there might well be others) that uses "smoke" to describe local weather phenomena.
didn't he drop it in a ditch?
Any sufficiently advanced technology is indistinguishable from magic.
Arthur C. Clarke, "Profiles of The Future", 1961
Every problem has a technological solution. People who didn't understand the technology called what they saw "magic" or "a miracle", and either embraced it or persecuted those who practiced it. Matter of undisputed, historical fact. Front projection cinema was considered "magic" by theatregoers when that was played in public for the first time: people actually ran for cover when trains came at them on the screen. I still see people leaning into turns during cop movie chase scenes (which are shot in such a way as to get people doing just that!), ducking laser fire during Star Wars; I know it's just a projection, but to some it's still magic.
<shootdown>the sand worms in "Dune" were not a problem at all, in fact they were essential to a large portion of the story; they were the whole point of the Spice plot: the worm *is* the Spice - as is specifically referred in the movie by the character Paul "Muad-Dib" Atreides.</shootdown>
I take exception to your claim that nobody has used short file names in decades, I still use short file names for the simple reason that I need to by the nature of the data that I'm dealing with (several million discrete text objects). It would be a criminal waste of time to give them all long file names, particularly given that data I need on any given occasion is simply searched via platform-level search tools (UltraFileSearch being one of them), and for speed it's all done in a virtual volume on a virtual machine session (don't ask me why, native searching on the dataset in win7 takes 3 or 4 hours, the same search on the same data on a virtual machine session in a virtual volume takes about three seconds).
not really surprising that Microsoft managed to get a mandate in for preformatting usb flash in xFAT as well, given that they're on the USB Flash Drive Alliance...
no, it's a specification. The SDXC logo is a trademark, for which to qualify you have to conform to the specification, including following the mandate that your card ships preformatted to exFAT. Otherwise, you don't get to use the logo and you don't even get to claim that your card is an SD-compatible device even if it physically fits the host adapter.
