Going fast on a loose surface takes considerable skill, it's probably the most difficult task you could set and AI driver. Sure a computer could in theory react faster than a human, but in the case of an AI driver it has to assess it's entire situation and take action in a split second faster than a human does. In this case 150ms.
Did Apple really need it's own version of industry standard DLNA?
"There are nearly 8,000 products on the market that are DLNA Certified [10]. This includes TVs, DVD and Blu-ray players, games consoles, digital media players, photo frames, cameras, NAS storage, PCs, mobile handsets, and more" http://en.wikipedia.org/wiki/DLNA
Android devices are already supporting this, you can bet the coming onslaught of Chrome tablets will support it too.
Apples wireless sharing offering is looking a bit silly.. why not just go with the industry standard?
IANAARD (I am not a active releasing developer) but the test would be...
1) If you were to do a hypothetical clean sheet redesign of an OS on a cocktail napkin, throwing out the rule book and looking forward the next 10-20 years. How much would you retain that exists in the *nix and NT* environment today? Probably very little, there's a lot of legacy layers right back to the bios that don't really serve the purpose they once used to.
2) Is your OS highly dependant on, and still religiously adhereing to legacy design decisions that date back more than one or two decades, developers are just doing things a certain way without really thinking about the reasons why they do, and if it still has meaning?
To give an example, and risk being modded down, *NIX "Everything is a file" is cute, and worked well when almost all data anyone needed to work with was a file, but is increasingly irrelvant in todays world as meaningful data is more highly linked, semantic and nuanced. The result is you need a layer or two of abstraction to be able to deal with the fuzzy weird ultra-interlinked metadata universe that is the world wide web and teh internets - its a paradigm or two ahead of the design decisions that underpin both the *nix and NT IS-verses. If I think in UNIX I have a trouble solving a web problem, if I think in teh webs OS suddenly seems so abstract. But I'm generally a poor confused ex-noob anyway, so thats possibly subjective.
But.. it's kinda cool it's all still working well enough, and it all still evolving. Linux is alive and well in edgy new OSes like Android, so perhaps there's nothing to worry about.
Try more like 1 in TEN MILLION, the 1 in 500,000 statistic you quote comes from a misquoted infographic, which points out 1 in five hundred thousand is the odds of being struck by lightning in the continental united states. Somehow people are repeating 1 in 500k? Refer to: http://boingboing.net/2009/12/30/odds-of-being-a-terr.html It's a eye-opener.
Internationally it's even less likely, consider international airlines like Qantas who have never had a airborne single fatality let alone a terror attack.
Because it's symmetrical. Who but the most evil cabal of engineers on earth would design such a connector to be a perfect rectangle? Without looking closely you have a 50/50 chance of getting the correct orientation.
Everything in computing from an RJ45 to IEEE 1397 have a obvious shape you can identify the correct orientation from.
Yes, yes. I know the trident is supposed to go "up" in relation to the trident logo by port on the port.
But this varies randomly from one manurfacturer to another, from device to device, and thats those that have the trident logo next to the port at all.
Mini-B USB, popular for small gadgets, thank god, has an identfiable orientation.
Looking at the photo it has a very clear exit for drainage at the northwest end. This means this is not a sinkhole necessarily (these usually drain into underground systems in limestone karst country), and a small possiblity just an oddly shaped gully. The small bits of melted looking metal are difficulty to explain without this being an old site for a foundry.
Also I would expect if this was limestone country the locals wouldn't find this odd let alone call this a 'crater' but just another sinkhole.
Transfering between Mars and Earth orbit is actually quite a low energy trip, if you are prepared to take a long time like a year or two.
The solution is simple.
Send equipment and infrastructre their in long slow ships, perhaps using spent rocket boosters to hold it all. Aero brake into the atmosphere and park it at a landing site.
Send canned primates there fast in a very small minimal ship. Perhaps even no bigger than an Apollo capsule, just punch it up to high speed with technology in reach like a plasma rocket. 14-25 days to Mars anyone?
Economies of scale applies here. Anything of volume production will be safe. Simply put, stuff made in a full scale factory will always be better, cheaper more accurately produced than anything out of a home 3D printer.
3D printers will mean few companies will get away with extortionate overpriced spare parts for things.
Something like a star trek replicator, which can print nutritious food and complex objects down to the nano scale, should also be able to print living organisms. Possibly even people.
I'd just print an army of IP lawyers to counter-sue.
That alone is quite something. I also read iPhones sell at about 200,000 per day and android phones outsell iPhone 2:1 in the latest report. It's not the fault of how good or bad the W7 phone is, there simply aren't enough smartphone totting hipstsers to buy them.
The market demand is being met by a huge range of phones, even if W7P was stellar, it'd have a tough job converting folk. iPhone users are difficult to pry away from their gadgets, Android technically speaking is so far ahead of the compeitition it's not funny and the pace of development is outpacing what proprietary OS could achieve.
Also, bare in mind Symbian based phones still have more market shre than either iOS or Android, and still sell well. This is kind of missed by the press somehow.
I'm going to go home and play with my T-Box and see if I can find GPL information under the menus or documentation somewhere. I know there are many linux devices out there that have exactly this.
1) Yes in theory its an organized system. A centralized repository rather than a distributed clusterfuck of files. In theory replacing the registry with config files is no better IF the developer chooses to put settings in random files all over your disk.
Ah, I still have fond memories of the day some time in the 90s that NT ran scandisk after a reboot, and then put up a message along the lines of 'Ooops, I just deleted your registry. Guess you're fucked, mate'.
And in the traditional unix world there were no 'settings in random files all over your disk'; system-wide files went in/etc and user-specific config in $HOME, all in nice text files that could easily be read, modified and backed up. The registry is an utter abomination in comparison (and the Gnome's registry turds are little better).
The registry is a database file, why can't be backed up? The story you describe had little to do with anything fundamentally wrong with the registry and more to do with a bigger problem, data corruption, exacerbated by the gawd awful decision to run Windows off FAT.
Traditionally UNIX systems were munted by some admin that made a typo in a text file, that said it was relatively painless to fix. In fact there are some extremely dangerous commands that are typos from something more innocent. At least a proper database contains that human error to some extent.
Each turbine blade is a sailboat at a tack angle. You could also think of the Turbine blades tacking naturally, because they rotate around an axis pointing directly into the wind, thus only relative air speed is required.
I'm no engineer, have no other qualifications than a knack for gadgets and I've been staring at these things for a while, planning to build one myself.
Stored energy in the mechanical is only used to pass equilibrium, a DDWFTTW cart would be able to sustain faster than wind speed indefinatley (as numerous youtube videos attest to).
Here is the crucial component to how this works that everyone seems to miss:
Relativity as a general principal seems to apply here. Naysayers seem to be working from a absolute frame of reference. Simple fact if you reverse the flow of air over a turbine, it is still absolutely able to extract rotational work from the relative air speed flowing along it's axis. You just need the right gearing to extract torque to wheels to drive a vehicle. If it was impossible you'd have to demonstrate why a wind turbine suddenly is incapable of generating work if it is merely moving relative to the ground, rather than anchored to the spot. (Excluding equilibrium to the air mass itself where it will not turn, however if it is turning, it'll produce thrust as it dumps momentum).
If you also imagine the turbine cutting helical path through the air, where the helix actually appears stationary (a kind of 1:1 with ground speed) if the air is then moving relative to the helix, there is of course a torque created by the turbine.
There are a number of ways to think about it that give you an 'aha' mental model of how it works. This is so simple I really feel slightly ashamed and embarrassed for every credentialed expert the world over that said DDWFTW was not possible.
Lets say you have a 50kph wind. Cart is at 0, you give it a little push off, here's what happens:
To begin with the wind pushes the cart just by bluff body drag until it gains speed. Lift to drag ratio means the counter-torque produced by the turbine will always be less than the winds total force on the cart. It'll inevitably move off down wind. That's easy to understand.
The real trick is passing equilibrium. As the air becomes still relative to the cart, the stored energy of the turbine and driveline torques against the air, producing thrust, which pushes you past.
Once past equilibrium, the airflow reverses over the turbine, relative to the cart. As the apparent wind speeds up the turbine is able to generate torque from the relative air flow, this powers the wheels. At 100kph down wind, you have 50kph of aero drag, and 50kph apparent wind to generate power. That turbine is cutting that helix through the air relative to the ground and the air is moving relative to the ground this equals available wind energy at any speed or vector provided there is wind you just need the appropriate configuration to extract it.
Again how the real credentialed experts and self-credentialed internet experts in forums missed that I don't know.
You know what's really beautiful about this? A correctly designed (perhaps variable pitch and gear ratio) turbine powered cart, can travel faster than wind speed in any direction, including directly into wind where it may be indeed possible to go faster than the wind into the wind.
Lasers are defeated by a reflective surface. It was about time sci-fi ditched them.
I'm so glad BSG went with projectile weapons. Projectile weapons are far more effective in a vacuum than an atmosphere and very difficult to shield against.
Oh and 'shields' / 'force fields' too - there is going to be no such thing. Force fields are even less scientifically plausible than FTL drives.
It seems to be lawmakers do not know what the Internet is. They need to understand that Internet does not actually exist, at least in the way they think.
It's one big dumb unified end-to-end communication network. What people think of as "Internet" such things like search engines, web sites and other forms content, are services provided by machines and real people who manage them on the other end of some tenous abstract link through a math address space. The internet itself is a pipe with no walls. It has no spacial volume - no memory, anything that falters in the tubes, after a while vanishes, never reaching it's destination.
Lawmakersm, please by all means make laws to go after those who do wrong, go after the actual criminals and their equipment.
But do not attack infrastructure, it's absurd.
Terabyte size hard drives are cheap.

Why not set up a "Swap Club" to pass around a big "Slut Drive" or three around?
It would be easy to wire up mains voltage to the USB plug. For extra geek credit wire it up to a bank of capacitors you had for a rail gun project that never eventuated.
+1 Better yet, randomly vary the transmit power to prevent simple triangulation of the wi-fi access points location. I considered this some time ago, I figured it would also need some code to figure out who was getting too close to the hidden antenna and drop transmit power or the connection outright to mask the actual location. I also figured the network would need to occasionally switch off and vanish if devices nearby were lurking and not sharing, even with that, no way to defeat passive wifi sniffing.
Promiscuously connecting your laptop or mobile device to USB drives is a sure fire way to get pwned. OSes generally do not have the same level of protection to a physically connected storage device as they do to their network devices.
