Submission + - Chips can self assemble themselves using smart fluids (techtripper.com)

An anonymous reader writes: Dr. Eric M. Furst of University of Delaware and his postdoctoral researchers are imbued in making scalable forms of technology a reality. The findings of the group of scientists were published on September 17th in the Proceedings of the National Academics of Science (PNAS). The findings are titled ‘Multi-scale kinetics of a field directed colloidal phase transition’. The article elucidates the team’s research on colloids which are microscopic particles, a hundredth in diameter of a human hair. It is illustrated in the article how these microscopic ‘building blocks’ can be instructed to autonomously assemble on their own, into specific structures.

the slightly scary thing is that you can buy your own ANPR System off the shelf. (I know that geeks can easy create it themselves using motion and some OCR tools - but, imagine selling this to normal people!!

That's not the scary thing. That's the only thing that is at all positive. You can't put the genie back in the bottle. And given that, the most empowering thing you can do for people is to make the same powers of observation available to everybody.

You comment he was waiting for the police, but neglect to mention the fact he was waiting for them with a shotgun in his hands.

*Bullshit.*

Watch the news clip. He states was holding his hands up empty when he entered the room, and the police do not dispute this. There was, according to some reports I have read, a loaded gun in the room.

The fact that you embellished this part of the story makes me suspect that some of your other statements also might be less than the unvarnished truth.

Comment Nobody knows what they are measuring (Score 4, Insightful) 213

People have been trying to measure intelligence for well over a hundred years now, but I have yet to see anybody precisely and fully define exactly what it is they are measuring.

And don't say IQ - the only thing IQ tests measure is the ability to do IQ tests. Read up on their history. There is nothing scientific about their origin.

Comment Speed limits won't matter when doing other stuff (Score 1) 650

If I can sit in my car and work at my laptop, or read, or phone the first client of the day I'll care a lot less about how fast I get there. Much like people today who take the bus or train to work.

Often people speed because they are driving and that' all they are doing. Most of the time they aren't even late, they just like going a bit faster and it's fun. You don't usually tell your taxi driver to put his foot down unless you really are late for that very important meeting.

Comment Re:The brain does not store memories (Score 1) 185

As funny as this mysticism clearly sounds to some, there are theories that some human memories are stored, "in the cloud" - when they are stored socially.

I have read ( but can't now find the reference :-( ) studies where groups of people have been asked to remember details from long stories, complex scenes, collections of objects etc.

One person will be the subject of the studies, the others will be actors. The actors 'remember' details that were definitely false - a red ball being blue for example, and reports it as such in front of the subject. The subject will then report remembering the same false memory - and honestly believe it. He can probably visualise the blue ball in his mind.

When you consider how many conversations you have with other people during the day, how much of that is creating, reinforcing and editing memories for you?

Submission + - Google Wallet Stores Card Data In Plain Text (darkreading.com)

nut writes: The much-hyped payment application from Google on Android has been examined by viaForensics and appears to store some cardholder data in plaintext. Google wallet is the first real payment system to use NFC on Android. Version 2 of the PCI DSS (the current standard) mandates the encryption of transmitted cardholder data encourages strong encryption for its storage. viaForensics suggest that the data stored in plain text might be sufficient to allow social engineering to obtain a credit card number.
