I could have stolen innumerable facebook passwords when I was in college. When you register your computer for the campus network, you can choose your hostname, which would then be a FQDN -- ..edu . So I registered the "facebook" hostname, and any time someone on the campus network typed in "facebook" (without the.com), it would resolve to me. I ran a redirect to my profile page on facebook.com, just for the hell of it (I eventually got, um, told that I should find better ways to amuse myself...).
It would have been trivial for me to host a false facebook login page, capture the credentials and then redirect to the real facebook login / invalid password page; I would have the password, they would get to log in (I'd like to stress that I didn't actually do this). I haven't R'd TFA, but I suspect you could do something similar on a much larger scale.
While the TFA's GTA movie is no doubt impressive, the Blender Foundation produced Big Buck Bunny, a (in my opinion) beautifully rendered ~10 minute short. You can download the rendered version here, and can even download the production data here -- it's released under Creative Commons I think.
It may not be quite up to Pixar's standards, but I think it's pretty slick (and no, I'm not affiliated with either company =) )
If you have fast enough feedback, then the displacements (and hence, angles) involved in the equations of motion for the inverted pendulum are really small, and hence the transcendentals involved can probably be approximated by the small angle approximation -- and then the "algorithms" (solutions to the equations of motion) are pretty simple I think.
Also, I'm not sure that standing a pencil on end is the same thing as an inverted pendulum, because the bottom end isn't secured for the pencil (correct?). For an inverted pendulum, if you oscillate the base fast enough the pendulum will remain upright (see the wikipedia article you linked) -- so it's pretty trivial to stand a pencil on end in this fashion, I think (just attach it to something that oscillates -- a speaker will probably do).
I'm curious as to whether they mean quantifiable handling (skidpad, slalom, etc.) or intangibles -- I suspect you can find a 60's Lotus which feels absolutely fantastic, but (due to skinny tires on hard rubber) gets outhandled by a modern econobox.
Actually, the shuttle's solution is alluded to in the article (I haven't read the paper, though):
Another is to shape the craft so that the plasma does not form in certain areas where a radio antenna can be placed. But this means the entire vehicle has to be designed around the communications system, which then cannot be changed.
Yet another idea is place the radio antenna in the nose spike so that it sticks out beyond the plasma. This allows radio communication until the antenna wears away due to ablation.
You're right that this is an entirely different method for communicating with hypersonic objects.
Ordinarily, this plasma absorbs and reflects radio waves at communications frequencies, leading to a few tense minutes during the re-entry of manned vehicles such as the shuttle.
Until the creation of the Tracking and Data Relay Satellite System, the Space Shuttle would, like Gemini, Mercury, Apollo, and others, endure a 30 minute long communications blackout before landing. However, the Shuttle can communicate with a Tracking and Data Relay Satellite during re-entry. This is because the shape of the Shuttle creates a "hole" in the ionized air envelope, at the tail end of the craft, through which it can communicate upwards to a satellite in orbit and thence to a ground station.
Of course, it's also easier to roll a stick shift car onto a flatbed -- shifting into neutral and disengaging the parking brake requires physical access alone, whereas shifting into neutral in an slushbox usually (right?) requires the key. Not exactly a showstopper if you're just gonna put it on a trailer, but still.
I could imagine YouTube voluntarily blocking Italian IPs (or Italy blocking YouTube), and a YouTube-via-proxy How-To being published in Italian (imagine that!). The result could be that YouTube "complies" with Italian law, Italians retain access to YouTube, and Berlusconi looks like an idiot.
The thing is, if advertising gets really, really good, I see that as a good thing. There are a lot of "long tail" items which I've never heard about, but which I'm sure I'd find useful. If I could be exposed to those (privacy concerns notwithstanding...), that'd be pretty neat. As it is, though, I just ignore essentially all advertising.
By trying to keep from them from abusive and probably discreditable domain names, you're probably just going to push them into ones that will cause wider contraversy.
While I in large part agree with this, I could imagine a "specialty" ISP (targeted at, say, hardcore gamers) with robust traffic shaping being a Good Thing. This fictitious ISP would throttle http/ftp/ssh/smb/etc. traffic, with the trade-off of better throughput and lower latency for gamers. Were I a no-holds-barred gamer, I could see myself electing to sacrifice some speed on YouTube or what have you, if it meant a better gaming experience.
Of course, this is an entirely hypothetical situation, wherein the Big Corporations have our best interest in mind (will that get me a +1 Funny?)...

Oh that's not a problem -- I'm into ultra high frequency trading ;)

Rather than this useless addition, why not have the browsers just not send the information in the first place? Or would that make too much sense?
Well, that would make cookies useless...but then, as you're an AC, perhaps you don't believe in cookies ;)
More out than in = no
It's called rest energy...and they're certainly not getting out more than they put in.
;)
That said, I'm more than a wee bit skeptical that this works. But if it does...well, I'm gonna go long in nickel and short the copper market

Furthermore, you can't switch anything off either. At best you can just turn it into a tiny capacitor ;)
You're wrong -- toolbars are awesome...
Quick! To the Batmob...ah screw it, I'll just walk.
Is there a similar site for WikiLeaks?

Duh, there's a lot of dirt in the rain...

I wonder how long until the lawyers start raining down from the sky.
That sounds... very nice. I mean, assuming they are falling a long enough distance, that is.
*mumbles something about lawyers being full of hot air, thereby reducing terminal velocity to a survivable speed*

It should only be fair use to make this kind of link:

Looks like this guy was rickrolled / meatspun one time too many...
Companies which at least attempt to adapt to the changing market seem to be doing ok...

I disagree, as does Ms. Streisand
Oh wait...

"CIA's counter-intelligence centre"
I can't decide if this is redundant or an oxymoron.
You know, intelligence about marble top counters, hardwood counters, laminate counters, etc.
Likewise. Did he spoof his MAC address to match his neighbor's? Not doing so would certainly raise suspicions in the AP's log.
