I'd always thought that equality was simply a transitive, symmetric, reflexive, binary relation that partitions a set into equivalence classes.
Very simple concept, I'd always assumed this was common knowledge...
Oh come on, this is one of the greatest open problems ever in mathematics, and everyone in complexity theory is aware that new "proofs" reguarding the P vs NP problem come out every month or so. It is one of the most common open problems that people try to solve. In fact, a common "practice" job or training for early grad students in the field is to find the errors in these proofs. Note I say find the errors, not determine if they have errors. They always have errors.
Look here for what the scientists in the field tend to think about p vs np proofs.

This is exactly why I would rather be a Computer Scientist working at a university or industrial research lab then a software developer. Because I want to create real new stuff.
Economists and Complexity Theorists work very closely together nowdays, especially around the area of algorithmic game theory. In fact there have been much more recent results in this area, for example I just read an interesting paper on the price of anarchy in network routing. http://www.eecs.berkeley.edu/~gvaliant/papers/SR_sub2.pdf
Many of the most popular complexity theory blogs often urge their readers to visit relevant economist conferences. Personally, I love this area, right at the intersection of algorithms, complexity theory, discrete mathematics, graph theory, operations research, optimization and game theory. Every single one of those fields is awesome by themselves imo, so algorithmic game theory is right up there for me.
yuck yuck yuck
keep these stories to yourselves, this is distressing me. If I knew software I was using was coding like this I would feel uncomfortable using it, even if it seemed to be working.
worry? What is there to worry about? If your house being on street view worries you... Then what doesn't?
Oh look, someones walking down your street!! They might be a serial killer!! Or worse, Jehovah's Witnesses!!!
Run to the bomb shelter!!!
Hackers tried to censor one guy by knocking out his twitter for a few hours. The irony of this is that, now his Twitter is getting a new follower every minute. Take a look for yourself, it was 1420, I pressed refresh and it was at 1433. Epic failure for the hackers, especially if they payed for the bandwidth.
It would be nice!
It would also put a stop to nonsense like this filter, do you ever wonder why stuff like this never gets off the ground in USA, despite the massive number of brain dead Fundies?
They have actually tried, I remember reading about it a year ago or so, but its always deemed unconstitutional instantly. Thanks to their bill of rights.
Absolutely. This is the difference between an average programmer / code monkey and a great programmer. People don't really see Computer Science as an academic field of knowledge. It is not learning about how to use computers, its not even about learning how to code, its the chemisty of data, the physics of computation. Computer Science was developed before computers even existed. Learning the fundementals of computer science, including algorithms and data structures, automata theory, algorithm analysis, theory of computation, information theory, cluster and grid computing, artificial intelligence, graph theory, combinatorics ect will place you light years ahead of programmers who know only the syntax of a few languages, and believes that counts as computer science.
so you're teachers couldn't instinctively tell you what (x-3)(x+2) would look like? Yikes maybe public education in USA really is as bad as people are saying...
Yes, matplotlib is pretty powerful, but they don't have a version for python 2.6 yet. You need to install it yourself:(
Lazy developers, 2.6 has been out for ages...
Whenever anyone mentions search engines I instantly think of that time a friend and I made a web crawler and let it running overnight...
200 MB of domain names:D
3% sounds like alot, 10 more points for Obama!
But seriously this is good news, you can't stop research just because of a short term crisis. New Discoverys have always led the way to better living conditions and can completly change the rules of the game. A single scientific discovery has the potential of doing more then any amount of legislation by itself.

I just had an epiphany!! This... explains... everything!!
The other 28% just don't know about it.

We use subversion at Uni for that. It gets the job done

seems a little like using differentiation to find the gradient of a straight line... except we know differentiation works
This article could have been renamed to "Why I chose to major in Computer Science instead of software engineering" and it would also make sense.
whoaaa! I'm a young man and I had no idea that I like sports and multi-level marketing, I thought I hated that stuff.
