You are right. I'm still new in this site and don't know how to upvote comments so I wrote this.

> The value of these systems is more teaching students how to work with parallel code. There are no practical applications to this, it's just to show that it can be done. You can spawn 64 processes in a Core I7 and it would be about the

I'm not agains the Raspberry pi foundation. I'm against the stupid old SoC they used and the low amount of memory. If they want to build a personal computer then add more memory, Raspberry PI now is an expensive microcontroller.

I can't believe the level of raspberry pi astroturfing present here. This board is so much more powerful that it can run full Ubuntu fast and the same chip is actually used to build very competent android tablets. I read things like "mind

Microwave oven radio waves are non-ionizing 2.4 Ghz and I suspect they cause several health issues to any living organism exposed to them, even for a short time.

Storage can be as reliable as you want, you only need to throw parity at the problem. Flash is one of the most unrealiable technology today, chips are ofter rated at only 10000 writes before bit-errors, flash is used as storage today thanks

You don't need anything fancy like negative frequency light bulb for that, only a regular light bulb that emits light 180 degree phase shifted to the already existing light in the room. It's actually impossible to do with a light bulb becau

BTW, CHDK doesn't use any exploit or vulnerability as all Canon cameras can boot from the SD memory, you only need to know the firmware file format, that it is of course already documented by the folks from CHDK.

Some Canon cameras are scriptable natively ( http://chdk.wikia.com/wiki/Canon_Basic ) and also using the CHDK extension. I understand the vendor's position on this, the market for scriptable cameras is tiny, you can easily destroy your ca

Unlike most startups out there, I believe Matasano is a purely consulting business with no product, IOS app or social site, and it got bought anyway. As the founder of a "cyber-startup" with no product and no social site, this is very encou

This post really set people off. Guess what, the cards were such a retarded idea, apparently in Defcon there were contests about who got more red or yellow cards, this actually caused lots of harrasment.

And what you would do if someone grab your hips. This is a very real situation as accidental hip grabbing is very common specially in crowded conferences. I believe hip grabbing and tatoo licking are VERY different situations, you see how c

Yes I removed that, I wanted to make a small joke but I realized people are too serious about this issue. Yes there are mechanisms for coercing behavior, jail for example. We already have laws governing sexual misconduct much more effective

No. There is already a solution to that problem, is called police. We don't need additional police.

I agree, brain control over impulses is what separate us from monkeys. But we are still monkeys, and the "creeper" guy over millenia tends to reproduce more over the polite guy, and so the creeper gen get selected and survives, that's how e

Those cards are the stupidest idea that I ever heard. This woman is complaining for being harrased in a place where 10000 men from 15-50 are constantly drunk, really. And the answer is giving out colored cards? nature forces can't be contro

I agree with all you said, but consider that humans in general are terrible at estimating risk. I believe being an entrepeneur is not that risky, and being an employee is not that safe either. The main problem that I see about seeing entrep

It's amazing how you people really believe all this. I don't mean to offend anyone, but I hate when people think of themselves a beautiful butterfly. Common people, employees, plumbers, etc. also have ideas, also have "bold blindness", they

It is not infinite capacity, in the same way that MIMO is not infinite capacity, IE you need phisically separated antennas for MIMO to work, and you need the same with OAM, the signal needs a specific amount of physical space to rotate. AFA

bps/hz measurements in TFA are bullshit without noise figures. Per Shannon-Hartley theorem, spectral density depends on the Bandwidth of the channel (assume infinite for free air) and noise. So what is the noise? of course DVB-T (Digital TV

It's false, implies everything the military uses is military grade. By that reasoning I'm having military-grade coffe this morning. The keyword you need is "defense-grade". Most fpga vendors sells "defense-grade" FPGAs, for example the Xili

Xilinx also has flash fpgas, the Spartan 3AN and I believe altera also should have one. About the rad-hard cost, yes they are >10k u$s each in most models but rad-hard ICs also are very expensive, I doubt an IC will be cheaper unless yo

The original article was censored so it's hard to tell if it's bogus or not. I believe it's still very interesting. Here http://bit.ly/JKatpV it's an older paper from the same author detailing a technique about reading thermal signatures
