Alton Brown is King Geek Chef and has a rule about unitaskers, single-purpose devices: don't buy them. Turn this into a unit than can also BBQ lamb and cold smoke fish and cheese, please.

Submission + - When Nerds Do BBQ 1

Rick Zeman writes: On this 4th of July, the day that Americans flock to their grills and smokers, Wired has a fascinating article on a computerized smoker designed by Harvard engineering students. They say, "In prototype form, the smoker looks like a combination of a giant pepper mill, a tandoori oven, and V.I.N.CENT from The Black Hole. It weighs 300 pounds. It has a refueling chute built into the side of it. And it uses a proportional-integral-derivative controller, a Raspberry Pi, and fans to regulate its own temperature, automatically producing an ideal slow-and-low burn."

After cooking >200 lbs of brisket fine-tuning the design, the students concluded, "“Old-school pitmasters are like, ‘I cook mine in a garbage can,’ and there’s a point of pride in that,” Parker says. “A lot of the cutting edge is when you take an art form and drag it back onto scientific turf and turn it into an algorithm. I don’t think we’ve diluted the artistic component with this."

Submission + - Reporter of an e-voting vulnerability raided in Argentina

TrixX writes: There have just been police raids at the home of an Argentinian security professional who discovered and reported several vulnerabilities in the electronic ballot system to be used next weeks for elections in the city of Buenos Aires. The vulnerabilities (exposed SSL keys and ways to forge ballots with multiple votes) had been reported to the manufacturer of the voting machines, the media, and the public about a week ago.
There have been no arrest but his computers and electronics devices have been impounded. Meanwhile, the information security community in Argentina is trying to get the media to report this notorious attempt to "kill the messenger".

Comment iOS users feel it (Score 1, Insightful) 311

I currently have a web radio transceiver front panel application that works on Linux, Windows, MacOS, Android, Amazon Kindle Fire, under Chrome, Firefox, or Opera. No porting, no software installation. See blog.algoram.com for details of what I'm writing.

The one unsupported popular platform? iOS, because Safari doesn't have the function used to acquire the microphone in the web audio API (and perhaps doesn't have other parts of that API), and Apple insists on handicapping other browsers by forcing them to use Apple's rendering engine.

I don't have any answer other than "don't buy iOS until they fix it".

Submission + - MIT's Bitcoin-Inspired 'Enigma' Lets Computers Mine Encrypted Data (wired.com)

Guy Zyskind writes: On Tuesday, a pair of bitcoin entrepreneurs and the MIT Media Lab revealed a prototype for a system called Enigma, designed to achieve a decades-old goal in data security known as “homomorphic” encryption: A way to encrypt data such that it can be shared with a third party and used in computations without it ever being decrypted. That mathematical trick—which would allow untrusted computers to accurately run computations on sensitive data without putting the data at risk of hacker breaches or surveillance—has only become more urgent in an age when millions of users constantly share their secrets with cloud services ranging from Amazon and Dropbox to Google and Facebook. Now, with bitcoin’s tricks in their arsenal, Enigma’s creators say they can now pull off homomorphically encrypted computations more efficiently than ever.

Most of us do have a need to transmit messages privately. Do you not make any online purchases?

Yes, but those have to use public-key encryption. I am sure of my one-time-pad encryption because it's just exclusive-OR with the data, and I am sure that my diode noise is really random and there is no way for anyone else to predict or duplicate it. I can not extend the same degree of surety to public-key encryption. The software is complex, the math is hard to understand, and it all depends on the assumption that some algorithms are difficult to reverse - which might not be true.

Comment Re:Bad RNG will make your crypto predictable (Score 2) 64

The problem with FM static is that you could start receiving a station, and if you don't happen to realize you are now getting low-entropy data, that's a problem.

There are many well-characterized forms of electronic noise: thermal noise, shot noise, avalanche noise, flicker noise, all of these are easy to produce with parts that cost a few dollars.

Comment Randomness can't come from a computer program (Score 2, Interesting) 64

True randomness comes from quantum mechanical phenomena. Linux /dev/random is chaotic, yes, enough to seed a software "R"NG. But we can do better and devices to do so are cheap these days.

I wouldn't trust anything but diode noise for randomness. If I had a need to transmit messages privately, I'd only trust a one-time pad.
