Gangnam Style Surpasses YouTube's 32-bit View Counter 164

First time accepted submitter neoritter writes "The Korean pop star PSY's viral music video "Gangnam Style" has reached the limit of YouTube's view counter. According to YouTube's Google+ account, "We never thought a video would be watched in numbers greater than a 32-bit integer (=2,147,483,647 views), but that was before we met PSY. 'Gangnam Style' has been viewed so many times we had to upgrade to a 64-bit integer (9,223,372,036,854,775,808)!"

Attack of the One-Letter Programming Languages 127

from the alphabet-soup dept.
snydeq writes: The programming world is fast proliferating with one-letter programming languages, many of which tackle specific problems in ways worthy of a cult following, writes InfoWorld's Peter Wayner in this somewhat tongue-in-cheek roundup of the more interesting entrants among this trend. "They're all a bit out there, with the possible exception of C. ... Each offers compelling ideas that could do the trick in solving a particular problem you need fixed.'"

This position seems to be popular among people that don't know the first thing about AI. So let me explain the situation from a point of view familiar to AI practitioners: A rational agent is one that acts as if it were maximizing the expected value of some utility function. That, in a nutshell, is the core of making decisions under uncertainty, and the basic recipe for a large part of AI. As part of the design of a utility-centered AI system, you define the utility function, which is precisely how you would tell the machine what to want. None of this "boggles the mind". It is almost trivial, actually. The difficult parts are perception, how to model future events to evaluate the expected value of the utility function in different scenarios, etc.

Don't worry. It is using a non-standard prototype for `main', and it forgot a few semicolons. It will stop working the next time the compiler is updated. Who knew that some obscure idiosyncrasies of the C programming language would save humanity? :)

I was programming at her age (BASIC on some 8-bit computer), and I turned out OK. My parents weren't very happy that I spent many hours a day in front of the computer, but that's what allowed me to have a great job as an adult.

I would just let the girl do whatever she is interested in.

According to Anses, the process of assimilating a three-dimensional effect requires the eyes to look at images in two different places at the same time before the brain translates it as one image.

Isn't that how normal vision works anyway?

That's why France doesn't allow children under the age of six to open both eyes at the same time.

Alienware's Triangular Area-51 Re-Design With Tri-SLI GeForce GTX 980, Tested 138

Posted by timothy

MojoKid writes Dell's Alienware division recently released a radical redesign of their Area-51 gaming desktop. With 45-degree angled front and rear face plates that are designed to direct control and IO up toward the user, in addition to better directing cool airflow in, while warm airflow is directed up and away from the rear of the chassis, this triangular-shaped machine grabs your attention right away. In testing and benchmarks, the Area-51's new design enables top-end performance with thermal and acoustic profiles that are fairly impressive versus most high-end gaming PC systems. The chassis design is also pretty clean, modular and easily servicable. Base system pricing isn't too bad, starting at $1699 with the ability to dial things way up to an 8-core Haswell-E chip and triple GPU graphics from NVIDIA and AMD. The test system reviewed at HotHardware was powered by a six-core Core i7-5930K chip and three GeForce GTX 980 cards in SLI. As expected, it ripped through the benchmarks, though the price as configured and tested is significantly higher.

NPR: '80s Ads Are Responsible For the Lack of Women Coders 786

gollum123 writes: Back in the day, computer science was as legitimate a career path for women as medicine, law, or science. But in 1984, the number of women majoring in computing-related subjects began to fall, and the percentage of women is now significantly lower in CS than in those other fields. NPR's Planet Money sought to answer a simple question: Why? According to the show's experts, computers were advertised as a "boy's toy." This, combined with early '80s geek culture staples like the book Hackers: Heroes of the Computer Revolution, as well as movies like War Games and Weird Science, conspired to instill the perception that computers were primarily for men.

If the only two choices are positive/negative (or thumbs up/thumbs down or some other equivalent 0/1 scheme), here's a formula that should work fairly well:

(n_positive + 1) / (n_positive + n_negative + 2)

So a single positive review gives you a score of .6667, and a single negative review gives you .3333. For large numbers of reviews, the score quickly converges to the actual fraction. If you don't have any reviews, you are at .5000.

The mathematical justification for this formula is that if you try to use a Bayesian approach to estimating the true probability of getting a positive review, and you start with a flat prior, this formula gives you the average of the posterior probability after observing the given number of positive and negative reviews. The full posterior distribution is a beta distribution with parameters alpha=n_positive+1 and beta=n_negative+1.

This formula is often used when applying Monte Carlo techniques to the game of go. I believe a lot of programmers simply start the counters of wins and losses at 1 to avoid corner cases (like division by 0), and they accidentally use the correct formula.

3D-Printed Car Takes Its First Test Drive 132

An anonymous reader points out this advancement in 3D printing. This week, at the International Manufacturing Technology Show (IMTS) in Chicago, Arizona-based automobile manufacturer Local Motors stole the show. Over the six day span of the IMTS, the company managed to 3D print and assemble an entire automobile, called the "Strati," live in front of spectators. Although the Strati is not the first ever car to be 3D printed, the advancements made by Local Motors with help from Cincinnati Inc, and Oak Ridge National Laboratory, have produced a vehicle in days rather than months.

While that is indeed the solution, it is also true that it is too easy to forget. Perhaps one could modify all commands to require the use of the "--" separator, or to warn if it's not present, at least if some environment variable is set. That could be very helpful for people trying to write more secure code.

How Concrete Contributed To the Downfall of the Roman Empire 384

concertina226 (2447056) writes "The real reason behind the downfall of the Roman Empire might not have been lead contaminating in the water, which is the most popular theory, but the use of concrete as a building material. Dr Penelope Davies, a historian with the University of Texas believes that the rise of concrete as a building material may have weakened ancient Rome's entire political system as Pompey and Julius Caesar began 'thinking like kings'. Concrete was used to build many of Rome's finest monuments, such as the Pantheon, the Colosseum and the Tabularium, which have lasted the test of time and are still standing today."

KDE and Canonical Developers Disagree Over Display Server 202

sfcrazy (1542989) writes "Robert Ancell, a Canonical software engineer, wrote a blog titled 'Why the display server doesn't matter', arguing that: 'Display servers are the component in the display stack that seems to hog a lot of the limelight. I think this is a bit of a mistake, as it’s actually probably the least important component, at least to a user.' KDE developers, who do have long experience with Qt (something Canonical is moving towards for its mobile ambitions), have refuted Bob's claims and said that display server does matter."
