Artificial General Intelligence That Plays Video Games: How Did DeepMind Do It? 93

First time accepted submitter Hallie Siegel writes Last December, an article named 'Playing Atari with Deep Reinforcement Learning' was uploaded to arXiv by employees of a small AI company called DeepMind. Two months later Google bought DeepMind for 500 million euros, and this article is almost the only thing we know about the company. A research team from the Computational Neuroscience Group at University of Tartu's Institute of Computer Science is trying to replicate DeepMind's work and describe its inner workings.

Comment Re:Driver's education (Score 1) 1651

I'm not sure that always holding drivers responsible for accidents with bikes in every situation is a good idea if you're at first trying to encourage cycling without a supporting infrastructure; it might be better to actually encourage better use of the roads on both sides before cycling is a common form of transportation in a particular area. While I've had a friend clipped a couple of times by cars (who often like to then just flee the scene), I've seen far more situations where the only reason the cyclist was not sent off of their bike was because of either sheer dumb luck or a particularly good set of brakes on the car that actually had the right of way (I usually see cyclists run a red light roughly once every week or two, and stop signs basically multiple times per day, regardless of what's actually happening at that intersection). Unfortunately with cycling as a main form of transportation being uncommon, while many drivers are unaware of how they should react many cyclists are also unaware of what they should be doing for basic safety and tend to treat riding on the road like riding on the sidewalk.

If my city had better bike lane coverage-- it isn't bad, but it's spotty and sometimes lazy-- it probably wouldn't be a bad idea, but when you're still at the point you need to be concerned about bikes going down the yellow between rows of cars (another thing I see not infrequently one some of the one-way streets) and speeding out into intersections from spots that are difficult to see from *both* sides of oncoming traffic I don't believe that sort of law would be appropriate. It's frustrating, though, when cyclists who are actually well-mannered and make excellent use of the don't seem to be getting the kind of protection (or respect from other cars) that they need.

A site I use (one which I would like to have a strong password) has an interesting system where they have very specific password requirements (uppercase, some numbers, letter, punctuation) which is all well and good... but then they only allow 8-12 characters. In the meantime, the username (which also requires a number in it, for some reason), is 6-20 characters.

I cannot fathom why they allow longer usernames but don't allow longer passwords.

Comment Useless idea (Score 1) 548

Local brick and mortar stores already get my business far, far more often for one primary reason: convenience. OK, a second reason too: shipping costs often drive the cost of goods up to what an item would probably cost with a sales tax anyway. The time when it's really useful to buy an item online is when it's a generic item being sold without the massive markup certain things get in physical stores (cabling, I'm looking at you). Local small businesses have much more to fear from chain retailers than they do from the internet.

Sales tax is a particularly frustrating tax, as it's fairly regressive and I'd personally rather see property taxes and the like be the big way to raise money for local government. Unfortunately, my state is one of the states in which the voters shortsightedly decided to cap property taxes.

Internet Is Easy Prey For Governments 314

Hugh Pickens writes writes "Douglas Rushkoff writes on CNN that the revolution in Egypt starkly reveals the limits of our internet tools and the ease with which those holding power can take them away. 'Old media, such as terrestrial radio and television, were as distributed as the thousands of stations and antennae from which broadcast signals emanated, but all internet traffic must pass through government and corporate-owned choke points,' says Rushkoff adding that when push came to shove over WikiLeaks in the US the very same government authority was used to cut off "enemies of the state" from access and funding. Rushkoff suggests that we use the lessons of the internet to build a communications infrastructure that cannot be controlled from the top. Back before the internet, many early computer hobbyists networked on Fidonet, a simple peer-to-peer network and now digital activists propose reviving such ideas with mesh networking over Wi-Fi networks that could connect inhabitants of an entire city without anyone having an internet service provider. 'Until we choose to develop such alternative networks, our insistence on seeing the likes of Facebook and Twitter as the path toward freedom for all people will only serve to increase our dependence on corporations and government for the right to assemble and communicate.'"

Actually, no. This is not why nerds are socially awkward; I'm usually fine with helping people with most tasks (even tasks I'm not particularly skilled at doing). The problem arises when I get asked to fix someone's computer and they are not even aware of the vocabulary used to describe the problem. In person this isn't so much of a problem (I can just sit down and look at it), but more often it's a question being asked over the internet or (even worse) over the phone. Spending 5 minutes to explain every term you use to try to diagnose a problem creates an issue that doesn't show up elsewhere; if someone asks me to help them move a couch, I don't have to spend 20 minutes asking where they want to move it because of communication issues, I can just pick one end of the damned thing up and help them move it. On the other hand, I cannot just tell my mother that if the router is going bad, I usually release and renew to see if that fixes it, then look at firmware updates if there are any, then begin checking wireless and port forwarding settings depending on what my problem is. She's still stuck at the IP address and which password (the wireless or the one set for the router?) she needs to enter. Moreover, a lot of people seem to actively try to avoid learning common terminology. Do I know where the starter or alternator in my car is? No. Do I have some basic information on what they do? Yes. Yet even intelligent people seem to just stare at their computer as if it might explode if they know too much about it. So while I'm fine with helping someone move if I'm free or assisting someone in cooking (though I'm terrible at it), helping most people with their computer is simply extremely frustrating.

China Hijacks Popular BitTorrent Sites 174

frogger writes "China is not new to censoring the Internet, but up until now, BitTorrent sites have never been blocked. Recently, however, several reports came in from China indicating that popular BitTorrent sites such as Mininova, isoHunt and The Pirate Bay had been hijacked. The sites became inaccessible, instead redirecting to the leading Chinese search engine Baidu."

Turbine Planning Console MMO 31

Turbine, the game studio that developed Lord of the Rings Online, said they are working on MMO products for consoles, for which they plan to provide details early next year. Kotaku notes that Turbine is also looking at incorporating user-generated content in future games. Quoting: "Turbine has the license to make MMOs based on the Tolkien universe until 2012, with options to extend until 2017. ... Turbine has its eye on open worlds and user-generated content, too: 'We're working on tech to let people... enable self evolving worlds,' [Turbine's communications director Adam Mersky] said. 'The idea is, we have these immersive, beautiful 3D worlds and they're designed by professional artists — but how can we let people create content in those... without "suburban sprawl," allow them to create gameplay environments.'"

Except that City of Heroes/Villains rarely costs more than $30 for most of the boxes I can think of. They almost always come with a free month, which is $15 off. Oh, and there are no paid expansions, so once someone buys the original box, that's all they're going to really have to buy. After that, revenue is either: A. Optional packs of small costume items or temp powers they sell (usually around $10). B. Codes for stuff from special boxed versions. While these tend to cost $20, they come with a free month once again, so they effectively cost $5. Oh, and you can just buy access to City of Heroes/Villains online and download the client. It's $20. I should also mention that when I bought my copy way back when, it came with several free things like maps and toys. It's pretty obvious that they're not making a huge amount from box sales (in fact, I think one of the developers has actually stated this on the forum).

Submission + - Best Buy Confirms 'secret' Website

Iberian writes: Courant.com confirms Best Buy does indeed maintain a second website for what one could only assume is for fraudulent purposes.

State Attorney General Richard Blumenthal ordered the investigation into Best Buy's practices on Feb. 9 after my column disclosed the website and showed how employees at two Connecticut stores used it to deny customers a $150 discount on a computer advertised on BestBuy.com.

Google Ads Are a Free Speech Issue 148

WebHostingGuy writes "A US Federal Court recently ruled that ads displayed by search engines are protected as free speech. In the case at issue, Yahoo!, Google, and Microsoft were sued by an individual demanding under the 14th Amendment that the search engines display his advertisements concerning fraud in North Carolina. The Court flatly stated that the search engines were exercising their First Amendment right of free speech in deciding what ads they want to display."
