How would a cell phone help you defend yourself against a shooter? Pulling out a phone and dialling just bumps you up the shooters "troublemaker" queue.
The cops are going to take twenty minutes to arrive no matter what so all your cellphone is good for is to provide some youtube footage (which the world might be better off without).
Um, yes it is. A student sat in an interesting class can still be receiving incoming messages. Are you telling me student is going to feel the phone vibrate but not get it out to read the message/reply to it.
This couldn't happen with old-fashioned note-passing where both people have to be sat near each other.
I say block cellphones and put an old-fashioned wired phone in each classroom for "emergencies" (though us oldsters seem to have survived school without that).
Cell phones won't prevent a Columbine anyway simply because the SWAT team takes time to arrive. The only use for a cell phone during a shooting is to provide youtube footage.
Put them in a room with a black WiFi box and ask them to tell you when it's switched on, preferably with some other "sensitives" as witnesses and making sure there's no cheating by the weasel-faced skeptics.
Having shown them what a real experiment is, give them one to take home so they can try for themselves whenever they have doubts.
After enough dismal failures they should get the message that it's all in their head.
the best we can do is ignore him from now on.

Wi-Fi Allergy a PR Stunt

...except the damage is done. The hippies and new-agers have already latched onto the story as yet more proof that WiFi is harmful and their neuroses are real.
Stunts like this aren't 'harmless'. We should publicly flog him, not ignore him.
His "CTR+HMAC" method relies completely on the quality of your nonce for security.
Software-generated nonces are notoriously error-prone, especially on systems which need to generate millions of them every day. Several SSL cracks have been based on guessing parts of the nonce.

Another New AES Attack
·
· Score: 5, Insightful
AES-256 and AES-192 are really AES-128 in disguise. They were created only to meet NIST requirements for three different key sizes, not from any practical security reasons (128 bits is definitely enough to prevent brute-force cracking).
The AES algorithm needs 128 bits of key for each pass through the encryption loop.
For AES-256 they select 128 bits from the 256-bit key for each round. Some of the key bits don't make it into the encryption loop until quite late in the process so in the final output they've only had a few rounds of encryption and can be brute-forced with much less than 2^256 effort. When you have some of the key you can go back and get a few more bits, and so on...
nb. The designers weren't stupid, they designed AES-256 to completely lose the key and this attack doesn't work against all twelve rounds of AES-256. The surprise is that somebody managed to extract the key out of a ten round version. This was unexpected.
nb. In AES-128 *all* of the key bits have been through *all* the rounds of encryption so inferring anything about the key by looking at the output is much more difficult (and hopefully impossible).
It could have made sense - if they'd showed us what the dreaded Vista did on that machine, but nooooo...
It would have been more useful to see boot times instead of 3DMark scores, but noooo...
Available free RAM right after bootup? Noooo...
What we are told, however, is that an OS can change the memory bandwidth. Who would have thought...? Microsoft's R&D division have really surpassed themselves this time!
The "men remain as aesthetically unappealing as their caveman ancestors" part doesn't hold up either. There's way more men going to gyms and taking interest in hair care products these days.
Well, yes, but a beginner isn't going to want to start loading textures manually and creating rendering contexts. He wants to type ship = LoadModel("spaceship"); DrawModel(ship);

I wonder if they'll publish the retraction of the story tomorrow, with similarly big headlines. They usually do ... right?

It's as much of a "computer" as my Casio G-Shock is. The Casio is microprocessor controlled so you shouldn't have a problem with accepting that.
Given that you can buy a 2Gb pendrive for about $5 I'd say you need to reevaluate your priorities.
Buy one, post your iPod back to Steve Jobs C/O Apple Inc., and include a note telling them to go screw themselves.
PS: It'll probably be 4Gb for $5 by the time you read this.
Come over to C++ - we have it all!

In short, a pretty retarded test.
Maybe they have a problem with backwards compatibility and can't just replace all the software without breaking all the handsets out there.
Generally speaking, there's supposed to be at least a few of them which aren't melting away to nothing.
3Gb/sec is the SATA interface speed. There's no way in hell the spinning disk will give you 3Gb/sec.
The "men remain as aesthetically unappealing as their caveman ancestors" part doesn't hold up either. There's way more men going to gyms and taking interest in hair care products these days.
Mod parent up. What the hell are they thinking??
This will likely have a negative effect on sales when people boycott any product with one in it.
It's much more likely that it's because more women go to more salons to have stuff done to them more of the time.
Besides, how are they measuring "beauty"? Tastes have changed - you can't compare 50's pinup girls with 2009 pinup girls.
Junk "science" at its finest.
He didn't say he can't write, he said he can't write cursive.
}being able to write in a readable script is in my opinion one of the most basic skills someone needs in our society
Huh? Most people's cursive writing is semi-illegible. Printing is much clearer.
The point about computers is also fairly valid. I get writer's cramp if I have to write more than a couple of paragraphs these days.
I'm pre-gen-X and I've never written in cursive. The educational system didn't get through to whatever part of the brain is responsible for it.
]The advantage of cursive over printing is that it is faster and less fatiguing to the hand.
Also makes it unreadable. I used to go out with a teacher and I never figured out how she could read the scrawl that was handed to her.
Came here to say "does it have a stress-relief area where you can throw chairs around" but you beat me to it.
Instead I'll say, "Is it just me or do the 3D graphics in those slides look like they were done using a Google product?"
Making game mods isn't very hard and a lot of them use scripting languages internally - best of both worlds.
But yeah, you could do worse than find out what he likes doing (but in this ADD world, non-gaming 15 year olds are rarer than hen's teeth).
Well, yes, but a beginner isn't going to want to start loading textures manually and creating rendering contexts. He wants to type
ship = LoadModel("spaceship");
DrawModel(ship);
...from there, new coders can move on to write buffer overflows and manual memory management code with C++ compilers.
Seriously, start with C++. You can do classes and objects later on but for Glub's sake start with std::vector and std::string FROM DAY ONE.
I'm pretty sure a 15-year-old isn't going to want to do "scripting", he's much more likely to want to do 3D graphics.
I'd suggest one of the 'game programming' Basics that are out there or even start by doing game mods.
They already tried this about five years ago with poisoned servers. What happened? The Kad search mechanism was adopted and the servers were useless.
The same thing will happen here, the protocol will change, the poisoners will have wasted a lot of money and achieved nothing.
