JPEG XR is actually quite good and is now an open standard. I recently did an extensive evaluation of JPEG 2000 vs. JPEG XR. While JPEG 2000 has slightly better compression quality (less visible artifacts) at the same file sizes it’s decode performance is substantially slower than JPEG XR (the same is true for encode performance, but decode is much more important). In my testing, one of the fastest JPEG 2000 libraries, Kakadu, is anywhere from 1.8 to 2x slower than JPEG XR at decoding files. Kakadu is a commercial framework, the open source OpenJPEG library is supposed to be substantially slower.

Compared to standard JPEG, JPEG XR has on average the same or very similar decode performance. The bottom line is that with JPEG XR you get compression quality and file sizes that are similar to JPEG 2000 with performance that is similar to standard JPEG. In my eyes, it’s the best successor available to replace JPEG. But it has a long uphill battle ahead of it.

That a software license covering a reference software implementation that Microsoft provided, not a patent license. They've made the patents freely available to implementers since 2007 as part of their Microsoft Open Specification Promise:

Microsoft has patents on the technology in JPEG XR. A Microsoft representative stated in a January 2007 interview that in order to encourage the adoption and use of HD Photo, the specification is made available under the Microsoft Open Specification Promise, which asserts that Microsoft allows implementation of the specification for free, and will not file suits on the patented technology for its implementation,[39] as reportedly stated by Josh Weisberg, director of Microsoft's Rich Media Group. As of 15 August 2010, Microsoft made the resulting JPEG XR standard available under its Community Promise.

His point is that local bandwidth is cheap but long-haul bandwidth is expensive and the equipment necessary to stream the kind of bandwidth Netflix needs to a significant portion of their customers simply can not be purchased and maintained for the current price of a residential broadband connection.

And I call that bullshit. For how many years have Comcast and other ISPs been overcharging their customers for the services they provide? If they sell unlimited bandwidth then they should expect heavy usage and they should be investing heavily in upgrading their network to support the bandwidth requirements of the future. Comcast's customers have been paying a premium for years to use the bandwidth. If Comcast was shortsighted enough to not see that bandwidth usage would be increasing dramatically then it's their own damn fault for not upgrading their infrastructure to keep pace.

The subscribers have been and are currently paying for the bandwidth. Level 3 shouldn't have to pay for something that Comcast's customers have already paid for.

Why do you think that it took 2 years to get Skype on the iPhone?

Because Skype's been too busy with their thumb up their ass trying to figure out how to "monetize" Skype-to-Skype calls over 3G for the iPhone. And, as others have pointed out, Skype has been available for some time on the iPhone, they've just restricted it to only working over WiFi up until now.

AT&T lifted the 3G VOIP restriction months ago and Skype should have been able to release an update the day that AT&T did that. After all, it requires MORE code to check if you're on a 3G connection and display an error message. When there are no restrictions you don't need any code to check what type of connection you're using you just use the data connection without regard to where it's coming from. But no, Skype sat on their asses trying to figure out - Hey, how can we get iPhone users to pay us more money? Then some conceded dumb fuck said - I know, let's start charging for Skype-to-Skype calls over 3G, that will get us making some money.

Yeah, the service that's always been free for any other computer, phone or any other device. Skype's going to start charging us for the 3G data plan that we're already paying for. Well, I'm sorry Skype but you can go fuck yourselves if you think I'm going to pay you for that.

Wii 2 Delay Is Hurting Nintendo 310

BanjoTed writes "Michael Pachter's ongoing spat with Nintendo regarding the Wii 2 is well documented. Pachter is sure it's coming, Nintendo says it's not. Now the analyst has gone one further by claiming that the declining sales of the Wii documented in the platform holder's recent financial statements will only get worse unless it speeds up attempts to get its successor to market. He said, 'The reason for this is clear: the software being created is just not interesting enough or compelling enough to drive Wii owners to buy more than two [games] per year, and most of those purchases are first party software. We can blame the third party publishers for making shovelware, or for misjudging the Wii market, but the simple fact is that the publishers have to develop completely separate games for the Wii because its CPU is not powerful.'"

Meet the Men Who Deploy Airstrikes 311

Lanxon writes "Wired followed US Army Staff Sergeant Kevin Rosner into Afghanistan to see first-hand the tools, tactics, and pressures involved in coordinating military airstrikes. This lengthy piece explores the people and technology involved in high-risk airborne warfare, from their perspective. From the article: 'Strapped to his chest, Rosner carries a handheld video player called a "Rover," built by L3 Communications, a New York-based defense contractor. The device, the size and shape of a PSP game console and costing tens of thousands of dollars, reads signals transmitted by the camera pods strapped to the underside of all NATO fighter aircraft. With his Rover, Rosner can see everything a pilot sees, from the pilot's perspective. On his back he carries a radio programmed with secure frequencies that tie him directly to the pilots overhead and to his unit's headquarters, several miles away. At the headquarters, another JTAC monitors a bigger, more sophisticated video terminal that displays the same video Rosner sees, plus other data.'"

The problem is that the fundamentalist/extremist Muslims don't fear the repercussions of their actions. The reason why they don't fear retaliation is because we don't have the resolve or guts to break their will. In ancient warfare you decimated your enemy until he had no desire or will to continue fighting. There was no care or hesitation for collateral damage. That type of warfare will never happen in this day and age (at least not from us) which is why we'll never be able to fully suppress zealots such as these.
