Well, since both manufacturers have transoceanic two engine jets, fighting over the number of engines needed for transoceanic flights is rather silly.
Oh by the way the FAA tells you ETOPS stands for Extended Twin-engine Operations (i.e. the standards and minima used for flying a two engined jet on a transoceanic flight, it specifies things like how far away from a landing site you can be based on single engine operation). Most pilots say ETOPS stands for "Engines Turn or Passengers Swim":-)
The 'whoop whoop pull up' thing is called GPWS (pronounced Jip-Wizz) and stands for Ground Proximity Warning System. Current GPWS systems can't look forward - all they can see is that the ground is coming up fast - hence some accidents have had "Terrain! Terrain! Whoop whoop! Pull up! Pu>CRASH!" as the last thing on the CVR. GPWS can only do so much.
EGPWS (which includes GPS so it can base warnings on rapidly rising terrain) fixes this shortcoming. I would imagine a new plane like the A380 will have EGPWS.
The fly by wire system did not override him. The pilot simply tried to break the laws of physics (the engines actually performed slightly better than nominal) - it takes time for those big turbine discs to speed up and the engine to go from low to high power. By the time the engines had spooled up, the tail had already started striking the trees. At that stage, it didn't matter how powerful the engines were - that was it. The pilot attempted to break the laws of physics, and had three people pay for it with their lives.
McArthur Job's airline disaster series of books has an in-depth study of the accident. Conspiracy or not, the way the pilot flew the plane doomed it.

Airbus A380 Under Fire

The aircraft COULD NOT be programmed to not allow those rudder deflections. The type of Airbus that crashed was an older, non-fly-by-wire (traditional hydraulic controls) type.
OpenGL not good for games? OpenGL is *fantastic* for games - all the games I play use OpenGL (things like RTCW:ET, True Combat: Elite (based on RTCW), Doom 3, Quake, the project I work on myself - Oolite for Linux).
It's quite possible you don't fully understand what OpenGL does since you mistook it for having audio support - OpenGL does not address audio at all (use OpenAL for that).
SDL + OpenGL seems to work pretty well, and SDL isn't for Linux - SDL is for Linux, BSD, OS X, Windows etc. SDL is platform agnostic. From my point of view, SDL is vastly superior to DirectX, because DirectX only allows me to target one platform. SDL allows me to target all platforms.
Or perhaps they just saw how useless and pointless the technology was. So you get some search results by using your telephone. You now have to type them into a computer to actually use the search results - so it's slower, more expensive and worse than typing the query. Unless the system was also going to read you the resulting web page over the phone, too. In any case, I thought that sort of thing was already being done by systems developed for the blind.
The interference drag on Moller's airframe would be a nightmare though. I bet it's a lot draggier than the equivalent sized regular airplane.
His Wankel engines are not even remotely capable of reaching the BSFC that would be required to get the claimed economy. Wankel engines are actually fairly inefficient (although smooth running). The Moller Skycar is a fiction that he's been claiming would be ready in 5 years for decades now.
An inverted plane (with a normal non-symmetric airfoil) flies upside down (badly) due to the angle of attack. The air flowing over the 'top' (now bottom of the wing) still goes faster than the air 'underneath'. In fact, the air never goes faster 'to catch up with the air underneath' - the air flow over the wing is MUCH faster than underneath (where it tends to slow a little). A wind tunnel can demonstrate this quite ably.
But it's a fallacy to say that x% of lift is caused by Bernouilli's laws (which predict the pressures very accurately) or the Coanda effect or... and y% is provided by Newton's equal and opposite reaction - it's not cumulative. 100% of lift can be explained by pressure differential, and 100% of lift can be explained by Newton's theories. They are just different ways of looking at the same thing.
From your garage to your destination, the M400 Skycar can cruise comfortably at 350+ MPH and achieve up to 28 miles per gallon.
Bullshit. The Moller Sky Car has been 'five years away' for as long as I've been alive. The math simply doesn't compute either - if you look at his engine specs, he'd need BSFC (brake specific fuel consumption) that is impossible with any known technology - let alone the kind of engines he's using.
Moller is merely a successful snake oil salesman who's managed to con investors for years.
I bought my last phone at the Phone Warehouse in Houston a couple of years back. Comon place to buy phones. I had no trouble buying outright a tri-band GSM phone which I could use with any GSM provider merely by inserting the SIM card from the chosen provider. It is not locked. All the Bluetooth features. It's not subsidized either. It took me all of half an hour to find (including driving time).
Who CARES if it was on BoingBoing or not. Myself (and many other Slashdotters) don't read BoingBoing so it is totally irrelevant if it appears there or not. It's quite frequent that news sites will carry the same stories, even outside of amateur-produced websites like Slashdot.
Partly because toilets in the United States are inferior, flapper based cisterns - rather than the Thomas Crapper Syphon system as god intended. With Mr. Crapper's system, you can impart significant momentum into the flush just by pushing the lever hard, which results ins a "WHOOOSH!!!!!!" flush. You also have the advantage that the water falls further before going into the toilet bowl, giving extra gravity assist. With a flapper valve cistern, you have no control over the flush strength.
No - a message box wouldn't be adequate. The distributor of the patented codec would still be liable for patent infringement.
Granted, the installation process should be *easier* - and Autopackage is addressing that. Perhaps there is room for someone to make a "Fedora Core 4 (Non-US)" (or Ubuntu Non-US or whatever) version with all the stuff covered by US patents added in the base distro, but the distro is only distributed outside of the US (of course, copies would leak through).
Those 'cheaper Windows admins' are in reality reboot monkeys. A *good* Windows admin is every bit as expensive as their Unix counterpart. You don't get cheap Unix admins because generally the reboot-monkey type simply doesn't survive, wheras they can as a Windows "admin".
We just had the reality of supposedly easy point-and-drool Windows based everything here. The difficulty of getting the Windows server based system to perform even just half the speed of the old Novell based system (running on old hardware) was so high that they had to hire consultants from Microsoft itself - who still took a month to gain barely adequate performance out of the system. I imagine the cost overrun is enormous and the TCO much higher than the Novell system it replaced.
They don't. In fact, a normal sliced nerve that's stiched together doesn't. When I was 15, I had an accident with a glass door (which sliced through my median nerve in my wrist amongst other things). This meant I had no sensation in my thumb or two adjacent fingers.
About 6 months later, when the nerves had all grown back, they had all gone the wrong way - if I stroked the inside of my middle finger, the sensation came out elsewhere on the adjacent finger. In fact, it was pretty random just where sensations would come out.
These days though the sensations all come out in the right place. The brain simply adapts and fixes the situation. It took very little time for the correction to happen, too.
Nerve cells will grow at a speed of about 1 mm per year
It's not that slow. When I was 15, I had an accident with a glass door that sliced into my wrist to the bone, completely severing the median nerve (and arteries, and tendons). If nerve cells grew that slowly, I still wouldn't have any sensation in the thumb and fingers 2 and 3 of my right hand. (In fact, if nerves grew that slowly, I would never recover feeling in my fingers in my lifetime).
Sensation in my finger tips was recovered in 6 months. That means the growth rate had to be >200mm per year.
Interestingly, when things had healed, the sensations came out in the wrong place - if I stroked one finger, the sensation would actually come somewhere else (the other finger). However, the brain rewired and now the sensations actually appear to come from where they should.
People play 3D games on Linux too. They even write them (points at sig). I think I'll be sticking with nVidia. At least they make an attempt at supporting Linux users.
Why is it that despite the enormous popularity of MS Office, Microsoft squeals like a stuck pig when someone (usually a government organization) chooses a competitor or a competing file format? No one else does that - everyone else learns from it and goes back to make their product better so they can win in future. Only Microsoft whines when they lose. It's not that they CANNOT incorporate OASIS into MS Office. It also seems a bit hypocritical when they moan about OASIS only effectively being supported by one product, when their own formats can at the moment only legally be supported by Microsoft thanks to their patents.
