Wikipedia says "1 Gbit/s for low mobility communication (such as pedestrians and stationary users)"
Given that I, a pedestrian and stationary user, get about 3 Mb/s on 3G, that is a jump of more than 300x. Even accounting for theoretical vs real-world performance it is insane to think that jump is going to happen in one generation of technology. Even fixed network speeds only get 10 times faster per generation.
Rubbish. They were too ambitious with their requirements for calling something '4G'. Seriously, 1 Gb/s connections? There was obviously going to be a generation between 10 Mb/s and that. If they had had their way we'd have that 2.75G nonsense all over again.
Basically now 4G = LTE. I'm fine with that -- especially as it is more than a just a speed upgrade, e.g. it has (supposedly) lower latency, and is fully IP-based.
You're missing the point. You should buy FLAC, not for your portable media player (use MP3 or AAC for that), but so that in future if there is an even more awesome format you can easily transcode to that one.
Oh wait, he's using wifi. That might work then, although I'd still be surprised if the round trip time is less than 0.5s, which is about the limit of usability.
I don't think it is the ISPs fault. Current mobile technology has too high latency to make VoIP usable. Hopefully that will change with LTE, since voice calls are just IP data as far as I know.
Sounds like you've never heard of forward error correction. And if they implement this using completely random codes, it would be impossible to 'crack'.
No, he means a sudden change. I know you're trying to be funny, but there's actually nothing wrong with using 'quantum leap' in that context - only an over-correcting smartarse would seriously complain.
Untrue. Nash equilibria aren't 'winning strategies' (see prisoner's dilemma). Randomness is an unbeatable strategy, but the best strategy depends on what your opponent does.
If they play completely randomly, you can't do any better than also playing completely randomly. But if there is any non-randomness in their actions you can definitely do better. For example, if they always play scissors, the winning strategy is clearly not completely random.
I hate to be the one to say it, but this does seem utterly pointless.
Not in the "we should be spending money on hospitals" sense, but rather "all you're doing is taking a rocket and trying to cripple its flying tendencies". There are so many more cool inspire-the-kids (which is the nominal point) projects they could do! Here are some crazier and more cool ideas I just had:
* A manned quadrocopter. * A massive computer-controlled Archimedes mirror. * An Asimov-style multi-speed travelator. * A Back to the Future hover-board using active magnetic levitation.
Those would all be way more awesome than "Oh its a rocket with wheels attached"./rant.
Bah I have one too and I wish it had gyros. And there are other things missing, like proper multi-touch, HDMI, a front-facing camera, and a camera button.
> I'm also quite fond of having vanilla Android, because it means upgrade immediately (I got a gingerbread upgrade notification today, actually)
If by 'immediately' you mean 'in three months', then yes! (Yeah I know... Cyanogen, etc.)
The Nexus One is great (helps that it was free!), but let's not distort the facts.
It seems the most innovative thing is not the actual eye-tracking, but coming up with an interface that is actually useful, and not just "the mouse follows your eye", which as the guy rightly says would be really annoying.
Does anyone know how the tech works? It looks like you can see two infra-red emitters in the sensor area...
Unlike most other cryptographic hash functions in use today, FSB can to a certain extent be proven to be secure. More exactly, it can be proven that breaking FSB is at least as difficult as solving a certain NP-complete problem known as Regular Syndrome Decoding.
Well it is theoretically impossible. But if you can create an easily updatable DRM system - like AACS - then you can make it annoying enough that your customers will pirate the video instead!
I agree. Slashdot is filled with these types of idiots. They pretend not to understand things to make points. They pick holes in new ideas that the inventor has *obvioiusly* thought of. They are generally opposed to all new ideas and technology.

I agree that he could care a lot less than he does. In fact I've heard it is one of the things that he cares most about.

Yeah. 3/14 is *exact* pi day.
Are you aware that on Android, apps are limited to 24 MB each? I've no idea what the limit is on iOS, but I can't see why 512 MB wouldn't be plenty.
You're missing the point. You should buy FLAC, not for your portable media player (use MP3 or AAC for that), but so that in future if there is an even more awesome format you can easily transcode to that one.
Here are a couple more promising-looking 3D CAD programs:
Heekscad: http://code.google.com/p/heekscad/
Freecad: http://sourceforge.net/apps/mediawiki/free-cad/index.php?title=Main_Page
I think they're both still quite far from being usable though.
Video tag. If they ever sort out the codec thing.

You'll have a long list of useless used codes. And junk mail generally isn't stamped.

What about this:

Yeah I know it is just a hash...
It could definitely be solved, since all that is happening is we are moving to European time (i.e. GMT+1). No changes to the OS are required.

It's starting to get annoying...
You can get a dumb-phone for a tenth of the price of the average smart-phone.
Yes, I'm sure they haven't thought of this basic fact that anyone who was trying to design this would think of...
Why does everyone on slashdot try to hard to pick holes in everything?
Flash reports what platform it is running on.
I think there are better ways to provide access to the internet to people in a hostile country than invading their airspace!
