It runs Ubuntu/Xubuntu 13.04 quite nicely booting off an SD card. You'd be hard pressed to get a better laptop for the money, and it's massively more useful than any table I've ever used.
And isn't it great that the creators of SuperTuxKart make that source code available. And wouldn't it be nice if Microsoft reciprocated and some of its source code available?
I wonder how many of the "Windows" users are actually just Linux users using Wine. Despite the Beta, I still do that for games (e.g. Civ 5) that don't have a Linux version.
This is obviously a prototype, but I wonder cheap you could make an operational system? Fuel costs are the the largest component of an aircraft's operating costs, and the most variable. Relatively slow (~100 mph) solar UAVs could make a lot of sense for UPS, FedEx, etc.
And you would be right. A "6000x12000 km" orbit is 12000 km from the center of the Earth at closest (since the Earth's radius is about 6000 km), and 18000 km from the center of the Earth at farthest. The energy of the orbit is defined by the average distance, which is 15000 km. The initial orbit is about 6300 km, so it's 2.4 times as energetic as the final, meaning a large burn by the rocket's upper stage to loose that energy and change orbits.
On top of that, the final orbit is also inclined at 45 degrees to the equator, compared to 28 degrees for the intial orbit. That requires another big out-of-plane burn which means more fuel.
Really, this is an orbit that you would only go to if you had big powerful hot rod of a rocket that you wanted to try out...
IMHO, they really need to push this for scientific computing initially, as they tend to buy in bulk and are not very binary dependant. They are claiming it is so low power (2.7 W) that it would be easy to put an array, say, eight of them on a 1U motherboard for 64 cores.
IMHO it's just further evidence that small electric vehicles are, and always will be, really dorky looking and totally impractical. Though I'm sure all five people in the target market will respond to this post.
As someone who has been on both sides as both an author and reviewer of scientific papers, "peer reviewed" doen't not mean something is automatically correct, simply that it is worthy of publication. It's closer to saying it's plausible, and should be out there for the scientific community to discuss. Correctness is more judged by reproducability over a timescale of decades, but even that is not definative.
Science is a lot more messy that a lot of people would like to believe...
When self driving cars become a reality, we can throw the idea of car ownership out the window. As it stands, 99% of cars spend probably close to 99% of their time parked and unused. That is inefficient.
It's actually quite efficient. That's why the parking lot of my apartment is full at night, but empty in the day, and vice versa for the parking lot at work. The demand for the cars is usually not even enough to really make use of unused cars. Short-term rentals make sense in a highly urbanized area (see ZipCar), but in most of North America, car ownership (or long-term rental) will still make more sense. Indeed, it's precisely the same as the prevelance of rental apartments in citys, but home ownership in more rural areas.
The real solution to infinite range with a self-diving electric car is induction chargers built into the road, especially highways. That way, the car only ever needs to use the battery when on short trips.
Are you predicting that there are going to be 10^16 scientists anytime soon? If they are all on Earth, that would be just less than 20 scientists per square meter (or about 65 scientist per square meter if you just count land area).
I've had a series of small, pocket-size bound notebooks. That plus a good black pen is just enough, always works, and I don't need to carry a bag or anything.
If you are teaching sysadmins, then yes Gentoo is the way to go. It teaches you very precisely what exactly you need and exactly what you don't. And, it keeps you getting reliant on a particular vendor's special config tools. If you can get and keep a Gentoo system running, you are genuinely distro-agnostic.
Flagstaff was the first Dark Sky City in the world, and achieved that by making nearly all outdoor lighting Low-Pressure Sodium (LPS) emission lamps. LPS is much lower power than High Pressure Sodium or Mercury (the typical alternatives), thus saving the city massive amounts of money on energy bills. In addition, LPS is monochromatic, making it easily blocked by even mildly sophisticated amateur astronomers. And the minimal skyglow has allowed the local research telescopes to survive, thus pumping tens of millions of dollars into the local economy.
Speaking as a professional (and occasional amateur) astronomer, Flagstaff is much, much better off because its Dark Skies.
The article seems imply that the fact that it requires so much maintenance is good because it's all local. But no matter where the maintenance jobs are, they cost money, and thus make it uncompetitive...
As an astronomer/astrophysicist, I find it hilarious that "physicist" rated higher than "astronomer" due to stress level. Apparently working with real data is much more stressful than with just theory.
And mathematicians are even higher, the hippie bastards...
If TV is any guide, make sure sure to practice your reflexes: you must be able to scream in terror at the slightest sound, movement or smell. Also, cultivate your sense of paranoia, because how else will you see the ghosts behind every action? Plus, go down to the hardware store and buy every piece of random electronic testing equipment, because any sensor will detect ghosts if you look hard enough...
Does education in "literature, history, politics and music" have any "demonstrable results or accountability"? Indeed, in my profession, I use my math education on a daily (if not hourly) basis, while I can't remember a single instance of literature, history, politics and music having any utility or relevance. My sister, a nursing student, has seen much of her class drop away because they couldn't do the simple math that they need for their job.
Math can be useful for much more professions than pretty much any subject taught in school, short of basic reading skills. Literature, history, politics and music are, frankly, just enrichments.

Do not think that the four-fingered hands of our robotic overlords are cartoonish at all.
Multiple floppies? Decedent capitalist pig-dog!
I did several installs starting from a single floppy with a kernel, shell, and ftp. Once on the network, nothing else is needed.

Well then the Centurions would have caught him, as there can't be that many Roman plebs flying around in an aeroplane.
...have to yell "OH YEAH"! and be red...

Crime is very low in Flagstaff, in fact among the lowest in the state: http://www.neighborhoodscout.com/az/crime/

I for one, do NOT welcome our flying robot overlords. The land-based robot overlords are much more effective.

Speaking as someone with a degree in Physics, I can safely say that I've only used literary analysis one time in my life: when learning it in school.
