The question is not breaking the key but determining the message underneath. The blocks are still only 128 bits in length, deducing these can be trivial, and that is how the HTTPS/SSL/TLS attach are accomplished, via known plain text attacks.

Today on CNN, the commentators after the Brennan press conference said that the CIA was correct in saying that no non-bad-guys were killed by drone strikes. That's because the CIA redefined bad-guys to be any human of fighting age (13-60). So, that means that Grandma and your kid brother are free to use encryption, because they definitely aren't terrorists. They get to keep their shoes on at the airport, so there you go!

Thanks TechyImmigrant! Lost track of the block size for a moment. Over the last three years, I've been developing a block cypher. I was surprised to see that AES sole security is XORing the key with mono-substitution translations of the plain text. The 128 bit version can be broken on my laptop...

Don't forget it is the NSA who approves what type of encryption are legal for citizens to own. In the case of AES relies solely that combining 256 random bits with 256 non random bits, sufficiently, is too difficult to decipher except for the most powerful computer systems.

There was a case where Best Buy (long time ago when 100MB Zip disk were the rage) re-sold Zip-disks containing someone's pr0n stash. So the source of the media doesn't really matter.

Any media, no matter what it's packaging can be a vector for viruses. USB is the most heinous because a device could be the size of a micro BlueTooth tranciever, report it self as a keyboard, and install gigabytes of virus code on a computer system. There's no bigger risk to security than physical contact.

Mexico really got the short end of the stick, but it happened for a couple of reasons. First off was the nationalization of oil production. US oil and gas companies had explored and drilled for oil and were reaping the benefits of harvesting it. Then the government declared these oil operations were owned by the government (part of a socialist movement, still alive in Mexico today).

Although Mexico was one of the most stable Latin American countries from 1920-1970, the oil crisis of the 1970's (caused by Nixion's decision to take the US of the gold standard and cause US currency to be 100% fiat) caused major inflation during that time period. This causes Mexico to default on its external debt, in 1982. Through out the '80s, the result was inflation and devaluation, causing major harm to many Mexicans who did not have inflation protection based on debt obligations (i.e. the common man).

As a US citizen, I can't agree with you more. We have perceived immigration issues, because millions of people have entered on foot or otherwise across the southern boarder without stopping at an immigration station to register. All because there is so much money to be had from performing manual labor compared to any type of employment in many so called Latin American countries. This, of course, is illegal, because laws were enacted to keep undesirables out of the country.

So at the same time, a law that is ineffective in discouraging people from entering without legal documentation, discourages many who would normally immigrate with complete authorization because the process is too cumbersome and limited. I personally don't know what a better process would be, but contribution the non-black-market economy is good for everyone, in the end.

I live in Nebraska and a lawyer friend of mine told me that non-compete clauses have little weight because there has to be parity between the contracted parties. So, unless you have a golden parachute that will pay you for your time during your non-compete duration, the company can sue your new employer, but will loose. This doesn't mean that you won't get socially blackballed for taking your client list with you to your next job.

Which is the opposite of states such as California and New York. My sister occasionally worked as an extra on a daytime-drama filmed in Manhattan (New York). Upon her sixth engagement, she was met by the union steward and told that if she were to return again she would have to present her Screen Actors Guild card or he would shutdown production for the day. Yearly membership cost approximately 6 days of pay. When the director invited her back, they agreed to pay her membership dues so that she could return as an extra again. Guild membership gave here nothing more than the privilege of a couple more days of uncredited extra work. If you got to another occupation that has union involvement, you have to join that union too.

This is what it means when a state does not have Right-To-Work legislation.

+ - How Computer Vision Algorithms Cope With Detecting Human Figures In Cubist Art

Submitted by KentuckyFC
KentuckyFC (1144503) writes "The human visual system has evolved to recognise people in almost any pose under a vast range of lighting conditions. But abstract art pushes this ability to its limits by distorting the human form. In particular, Cubism seeks to represent three-dimensional objects on a two-dimensional plane by juxtaposing snapshots from different angles. The result is that a Cubist picture contains many ‘fragments of perception’ of the same object. That's why it is often hard for people to recognise the human figures that these pictures contain. Now a group of computer scientists have tested how computer vision algorithms fare at the task of spotting human figures in Cubist art. They compared a variety of different algorithms against humans in trying to spot human figures in 218 Cubist paintings by Picasso. Humans easily outperform all the algorithms at this task. But some algorithms were much better than others. The most successful were based on so-called "deformable parts models" that recognise human figures by looking for body parts rather than the entire form. Interestingly, the team says this backs up various studies by neuroscientists suggesting that the human brain works in a similar way."

TheRealHocusLocus (2319802) writes "So here we go. The New York Times is quoting "people briefed on the matter" who allege that the JP Moprgan data thieves "are thought to be operating from Russia and appear to have at least loose connections with officials of the Russian government". This becomes a front page item on the Times. Drudge Report dipped into their stock photo bin and plopped a huge Putin photo, one of those pensive ones like he's hiding something.

I remember a time when a respectable news source would be reluctant to take such a claim to the front page on an unnamed single source, let alone tossing out those "loose connections". And of course the Sanctions are brought in, it could be an act of "retaliation"... in case you didn't know. My bullshit detector is going off. I've seen the former Soviet Union evolve into an amazingly diverse culture that is well reprresented on the Internet. This culture has grown alongside our own and runs the gamut of characters: tirelessly brilliant open source software developers, fine commercial products, basement kiddles from script to l33t, and yes — even groups affiliated with organized crime syndicates. This is no surprise and these exist in the US. Ask your local bank what card skimmers are. Are we ready to go full-political on this computer security issue, where who and where diddit is more important than how to lock it down? If Joe Smart from Nashville owns a Russian bank would we expect to see a pensive Obama photo in the Moscow Times?

Let us stay this madness. How do you Slashdotters feel about these growing 'tensions' and what can we do to help bring some moderate balance to the table? And my Russian friends, how do you feel about being implicated thus? Are you all KGB agents? You can speak up, we're all alone here. Signed: been through one Cold War and don't want another."

Most non-scientists are not in a position to evaluate the claims of any given scientist.

I'm pretty sure that was the argument the Church had against releasing full, translated copies of its data, a.k.a. the contents of the Christian Bible.

This argument doesn't pass the sniff test. It is the job of a "scientist" to present claim and data that supports said claim in such a way that it may be consumed by anyone and still stand on its own, only then is there "consensus."
