Flying kites at high altitude isn't as easy as it seem: pretty soon you get a lot of problem from the line(s), chiefly the weight of the line, but also line drag.
The former problem is essentially a strength vs. weight problem that even high tensile lines made of dyneema won't solve easily (above 400/500m, a 6m parafoil can very well sit there and refuse to climb with standard lines).
The latter problem introduces a problem of angle, since the line becomes curved under the wind drag, which makes the section right under the kite more and more vertical as it climbs, which in turn "flattens" its incidence angle and reduces its lift. It's always possible to modify the incidence on the ground to compensate, but takeoff can get dicey then. And of course, the wind drag on the line also tends to pull the kite down, and it's not negligible with a lot of line up.
So yes, it should be possible to use kites to generate power, but there will have to be a great deal of electronic magic to regulate everything, down on the ground and up in the air, if high altitude flying is to be more than stunts performed by enthusiasts on good days with (semi-)controlled conditions.
Then Earth will form the Coalition of the Willing, composed of the United States, Tonga, Estonia, Palau, the Marshall Islands, Micronesia, Samoa (and Poland, you forgot Poland!) and will send interplanetary missiles on Venus, because Venus provided support to the cometian terrorists...
Well, no need for that. The 3 main distros (stable, testing and unstable) simply represent the "level of paranoia"/package staleness choice one can make, i.e. stable is old stable packages, testing is reasonable up to date packages with a few problems, and unstable is cutting edge and you're on your own with problems.
What one may with is an additional level between stable (which is truly quite stale) and testing
with perhaps a pre-configured installer that sets up the most comonly used packages on a server.
That's what tasks are for. What you really want (and what everybody wants) is an easy intuitive point-and-click thingy that'll finally replace dselect.
I guess what I meant was, at this point, DNF has been so much vapor over so many years that I don't know why anybody even bothers reporting anything about it. IMHO It'll start being newsworthy again the day it goes officially beta or gold.
I was under the impression that the US had spent billions of dollars seeding the north atlantic ocean with passive buoys and magnetic anomaly detectors (MAD) as a net to detect and triangulate soviet subs. This is cold war stuff that could perfectly be reused to counter new threats from terrorism, since it's been there and working for decades and, presumably, still in operation. So why deploy new ones?
It seems quite complete, and it's released under the GNU Free Documentation License. Those are great. But even if it's a "complete beginner's guide", I wish the author had touched a bit on remastering, and the possibility of customizing Knoppix. I know it's not for beginners, but still, if it's explained well, I believe it's accessible to most.

The rules of robotics are just another form of computer security
The rules of social behavior amongst humans, what we call "ethics", is also a form of "human security". I believe ethics are a set of self-imposed rules that people follow, that's nearly engraved in the human brain, simply because if they didn't follow them, the race would destroy itself. Evidence of this is in psychopathic individuals: they destroy a lot and society (people) go out of its way to stop them, not because it's rational, but because it finds what psychopaths do shocking. But the result is the same - the human race' self-preservation.
Robots on the other hand, when they evolve enough to be truly sentient, won't have millions of years of evolution behind them, and therefore will need some form of safeguard to avoid killing themselves (and us humans, but that may not be their priority in the end). But I'm not sure there's a need to code it into their "brains" in the form of ethics, like us biological entities. Surely some simple coding rules would suffice, and surely they don't need the emotional-ladden "ethics" we use to obey them.
as in more visual. Most ground-based beacons and VORs and the like can provide "tunnels" to airplanes, and autopilots can bridge the gap in between places with beacons, but until now it was rather conceptual. That new technology allows pilots to visualize directly the virtual route.
Commercial airplanes could benefit from this today, which is what's great.
Roland Pickypail is shameless self-promoter who crossposts everywhere and even stoops to astroturfing to get people to think he's some kind of big, influentual journo.

NEWSFLASH: most of the world doesn't speak english natively, and therefore see no connotation in the name "jackito"
Conversively, Toyota commercialized a car called the "MR2" that, in french, sounded like "oh shit". Guess what? it never sold well here.
Corporations in one country choose names that sound good locally and sometimes manage to offence people elsewhere. No need to get smug, or all giggly about it, unless you're some teenager who finds these things funny.
Isn't the wording of the post a bit along the lines of NASA polit-speak? Unique environments, geothermal heating -- voila NEW LIFE FORMS! Let's submit a budget request for a probe to an ice world to look for life!

drive 100 miles toward the center of whatever continent you live on and you'll find that the earth is no where near over-populated.
Over-population isn't defined by the lack of personal space between two human beings, it's defined by the sustainability of their exploitation of the planet.
As of today, there are 6+ bn people on Earth, about a third of which (the rich ones) already manage to over-exploit most of the planet's resources and destroy parts of it. I let you imagine what it would be if all 6 bn would start consuming even a third of what an average westerner consumes.
This planet should host about 1 to 1.5 bn people comfortably and sustainably. Any more than that is too much.
We humans aren't going to have any immunity to these microbes that have been isolated for 500000 years.
1 - What tells you these microbes are necessarily harmful to humans? lack of contact with them for half a million years suggests humans may not be their carrier hosts of choice actually.
2 - There are already thousands of deadly yet-unknown diseases lurking right here on the surface, in remote rainforests, waiting to be released by idiotic poacher. One or two more from the bottom of an underice lake won't make much difference.
3 - So what? humanity will either evolve natural defenses, or science will help the natural process, and there are way too many humans on this planet already. I can't remember who said that Gaia (the planet Earth considered a complex living entity) has a form of AIDS disease that's running amok and depleting its resources from within, and it's called Humanity.

Admittedly, a lot of advice given in the book can be found on Google, but it is nice to find it in one place.
Well duh...
Google knows everything, therefore includes any book, just like sea water contains sugar (and almost any known chemical compound) but it's so diluted it would make a lousy sweetener. Therefore, books are good, whether or not Google contains the information in the book.

I never really saw any reason to own a Tablet PC, what does it have over a labtop?
It's kind of harder to haul test tubes, microscopes, petri dishes and centrifuges?
Well, can you write "make" with a stylus?
I'd be more worried about sending things like ctrl-c to programs. Or worse, using emacs.
Linux for servers, and now on the tablet. At some point, it should find its way on the desktop...
A Debian Server variant would indeed be good -

Smugglers have nothing to smuggle since DNF didn't happen at all.
It's not a low in gaming, it's a spectacular low in PR, a typical hype building that starts much too soon and falls flat on its face.
