Submission + - AMD tweaking Radeon drivers to reduce frame latency spikes (techreport.com)

crookedvulture writes: "Slashdot has previously covered The Tech Report's exposure of frame latency issues with recent AMD graphics processors. Both desktop and notebook Radeons exhibit frame latency spikes that interrupt the smoothness of in-game animation but don't show up in the FPS averages typically used to benchmark performance. AMD has been looking into the problem and may have discovered the culprit. The Graphics Core Next architecture underpinning recent Radeons is quite different from previous designs, and AMD has been rewriting the memory management portion of its driver to properly take advantage. This new code improves frame latencies, according to AMD's David Baumann, and the firm has accelerated the process of rolling it into the official Catalyst drivers available to end users. Radeon owners can take some comfort in the fact that a driver update may soon alleviate the frame latency problems associated with AMD's latest GPUs. However, they might also be disappointed that it's taken AMD this long to optimize its drivers for the now year-old GCN architecture."

Submission + - That link you just posted could cost you 300 Euros (the-digital-reader.com)

Nate the greatest writes: Do you like to tweet or share links to interesting news articles? According to a coalition of Irish newspapers, that makes you a pirate. The National Newspapers of Ireland has adopted a new policy. Any website which links to one of the 15 NNI member newspapers will have to pay a minimum of 300 euros, with the license fee going up if you post more links.

Note that this is not a fee to post an excerpt or some punitive measure for the copying of an entire article. No, the NNI wants to charge for links like. It's almost as if this organization has no idea how the web works. Or maybe they have found an elaborate way to commit suicide.

jfruh writes: "Those Nigerian spam scams of the last decade may have just been the first step in a looming African cyber-crime wave. Africa has the world's fastest-growing middle class, whose members are increasingly tech-savvy and Internet connected — and the combination of ambitious, educated people, a ceiling on advancement due to corruption and lack of infrastructure, and lax law enforcement is a perfect petri dish for increased cybercrime."

Submission + - The 2013 Slashdot Free Education Challenge (edx.org) 2

DiamondGeezer writes: Most slashdotters would agree that with the ever rising cost of higher education and the ever-present need to keep ourselves ahead of the game, the game-changer might well be the free massively online education courses now being rolled out.

With that in mind, I'd like to suggest a 2013 challenge for as many Slashdotters as possible to enrol in at least one free online course and report on the results back to the providers.

Some courses have had mixed reviews (for example this one got a pasting) but the only way these massively online courses will improve and go mainstream (and maybe get real-world accreditation to boot) is to take courses and provide large amounts of feedback — oh, and learn of course.

I've chosen edx.org as a starting point and I've already signed up to Introductory Statistics at Berkeley.

We could call it "The Slashdot MMO learning challenge". Cost: nothing but time which you would normally be frittering away playing WoW or Eve or something. There are no dragons to slay or grand space battles to conquer for virtual resources, but there is a future universe of education to be found.

Who's with me?

Submission + - Command & Conquer recreated in HTML5, with multiplayer!! (adityaravishankar.com)

An anonymous reader writes: Back in the deep dark days of 1995, computer gaming was very different from what we know today. It was slower, blockier, and everything was a pain to install. Still, many gamers of the era have fond memories of the original Command and Conquer, later renamed Tiberian Dawn. This real-time strategy game pitted the Brotherhood of Nod against the GDI in all-out war. Now you can play this classic PC title entirely in your browser . What an age we live in.

An enterprising coder, Aditya Ravi Shankar, actually recreated the strategy game using nothing but HTML5, where it runs on 69k of Javascript. Why did he set out on such an adventure? For starters, Shankar’s attempt was a self-mandated undertaking in order to improve his coding skills, where he gave himself a one month window to rebuild the game in the browser, and had to comb through the original game’s files in order to obtain all the right sprites, sounds and specs.

According to Shankar, “In hindsight, I might have wanted to take smaller steps and make a tower defense game instead of jumping directly into an RTS. Trying to do the whole thing in under a month all by myself wasn’t the smartest idea.”

This implementation of Command and Conquer has been developed entirely in HTML5, so any modern web browser should be compatible. In its current incarnation you can’t play the entire game. You can run through the first few levels of both campaigns, but there is online multiplayer support through node.js.

All the assets and audio are lifted directly from the original game, circa 1995. The developer stresses that the port was not created for financial gains, but only as a proof of concept. The game itself is available as a free download from EA , and has been for a few years. Considering this, you might be able to get away with calling the HTML5 port fair use.

The game itself plays well in most places. Unit movement seems a little clumsy, but this might be a fair representation of the original game. The multiplayer skirmishes are good for a few rounds of fun, but many of the structures and units from the full game are missing at this point. Assuming the developer does not get a cease and desist, more content could be added later.

Comment The trend is towards closed computing. (Score 4, Interesting) 284

It's always a little amazing to see how people cheer on the leaks and cracks when they appear in a closed system, yet continue to support these closed systems with their money and attention when open systems are available.

It's just this very weird disconnect in consumer psychology. You don't have to crack a PC (yet) to do what you want with it. But you make a computer small and flat and suddenly you find yourself having to pay $1+ for every little program, from a collection of programs that somebody else has decided you shall have access to. You don't see the "fuck the man" attitude at the store, you only see it when a Scandinavian high schooler comes up with a crack for your game console and the manufacturer tells you you can't have it.

I just don't get it. How many years past DeCSS are we and banging our heads against the same wall?

Efficiency in wireless communication is something of a purple elephant, mostly due to interference concerns that aren't at issue in wired Ethernet transactions. True, wired connections will have the occasional collision (though this is largely solved by modern algorithms and operating systems) but digital transmissions over an analog medium are difficult enough when they aren't running into each other in the air. And then you have other interference introduced by microwaves, whether from devices like cell phones, microwaves, or sunspots. It's a very noisy environment!

The concept of using algebra is a unique step forward in this field. Most here would agree, if you're in a crowded cafe and trying to carry on a conversation, it's easier to shout "Pythagoreas" than to talk about squares and triangles. But with computers it happens to be exactly the opposite because they're designed to compute -- it's what they do and what they like to do. So feed it generalities and, often, it can come up with specifics, much like the Monty Hall Paradox.

The next step appears to be to move from algebraics to broad descriptions of the type of data you want to download. This is waiting on computers with a great deal more processing power and perhaps emergent AI, but there will come a time where instead of feeding a bunch of packets over a noisy channel the Internet will simply say to your computer "short film with 20-something actor wondering whether to marry now or enjoy life for a while longer" and your system will fill in the rest, completing the transfer mathematically. This is down the road a ways, but newer technology such as lossy compression for data is already available and potentially lucrative for those who are willing to think outside of the conventional box and try something with a few more holes in it.

Comment Couldn't be happier. (Score 1) 1002

As much as some quarters would dismiss today as slacktivism or a cheap stunt, the Internet has needed for a long time now to take the political process seriously.

There is this sort of mythology that has been embraced regarding the idea that technology can route around misapplication of the legal process; that some combination of steganography, encryption and dark fiber will always allow us to enjoy the freedom we've taken for granted on the Internet. But we're on borrowed time. The abuses of copyright law as it currently stands are myriad, whether it's publicly funded research locked down in private journals, or fair use aggregation and citation of news coming under legal attack, or DMCA takedown notices being inappropriately filed, without repercussion, by "content owners" who don't actually have a right to the content they're taking down.

Hide inside TOR if you want to, but the fact of the matter is some truly awful precedent is being set and horrible legislation crafted because only one side reliably shows up to this fight. Take solace in the idea that someone will make you a "free Internet", at least until encryption is illegal over cable and airwaves. Enjoy your privacy until it becomes mandatory to provide ID to browse the web -- commercial interests already examine everything you do and put it in your permanent file. At the end of the day, do not expect technology to provide an answer when the law sets the specifications for the Internet.

I couldn't be happier that the Internet is finally creating a notification and response system for awful legislation. Now it's time to let your representatives know they'll lose your support if they draft, sponsor and pass anti-Internet bills. If they ignore you, vote Rastafarian. Also, consider buying your movies and music used, selling back to the used market, and encouraging your friends to do the same. It's high time to send a fuck you back, because right now everybody thinks we're a joke.

And I think it's wonderful that somebody has come up with a low-cost, low-profile system new programmers can cut their teeth on. But given my background, I also know it's a bad idea to mix sugary fruit with silicon.

That said, are you concerned that the name of the project will lead to gastronomic problems with its users, or are you encouraged by the relatively trouble-free history of Apple Computers in this regard?
