Google Defines the Sides in the HTML5 Video Fight

A few hundred words from Google Product Manager Mike Jazayeri announcing that Google would be supporting WebM and Ogg Theroa instead of the H.264 video codec in Google Chrome for the HTML5 video tag has lead to enormous controversy in browser and video circles. Now, Google has explained in more detail what’s its trying to do, and ends up defining the sides in the HTML5 video fight.

In his latest post, Jazayeri said that the prior “announcement was solely related to the HTML “Video” tag, which is part of the emerging set of standards commonly referred to as “HTML5.” We believe there is great promise in the tag and want to see it succeed. As it stands, the organizations involved in defining the HTML video standard are at an impasse. There is no agreement on which video codec should be the baseline standard. Firefox and Opera support the open WebM and Ogg Theora codecs and will not support H.264 due to its licensing requirements; Safari and IE9 support H.264. With this status quo, all publishers and developers using the tag will be forced to support multiple formats.”

This last point has been ignored by some critics who say that “H.264 is what we need.” While Jazayeri acknowledges “that H.264 has broader support in the publisher, developer, and hardware community today (though support across the ecosystem for WebM is growing rapidly). However, as stated above, there will not be agreement to make it the baseline in the HTML video standard due to its licensing requirements.”

I, for one, welcome our Linux Penguin, Jeopardy Overlords

“I’ll take evil, science-fiction computers for $2,000,” Alex. OK, we’re not quite there yet, but in the early going, IBM’s Watson supercomputer beat Jeopardy super-champions Ken Jennings and Brad Rutter in a practice round. And, what is Watson running? Linux, of course.

There’s nothing surprising about that. The fastest of fast computers have long used Linux In the latest TOP 500 list of the world’s most powerful supercomputers, 459 of the Top 500 supercomputers were running Linux.

Watson is made up of ten racks of IBM POWER 750 servers running Linux, and has 15Terabytes of RAM; 2,880 3.55GHz POWER7 processor cores and operates at 80 Teraflops. You’re not going to find one of these at your local Best Buy.

Watson isn’t just an ordinary supercomputer though crunching linear equations, the Linpack Benchmark, at ever faster speeds. By comparison, that’s easy. No, IBM has been working on Watson for almost four years on solving the problem of ‘understanding’ natural language questions.

Google removing H.264 from Chrome does nothing to HMTL5

In some technology circles, you’d think Google was proposing throwing cats into a wood-chipper from the way some people are reacting to Google’s announcement that it was focusing its support on its own open VP8/WebM and Theora video codecs, and dropping support for H.264. This is not a step back for openness; any kind of new road-block for HTML5; nor is it going to ruin the Chrome browser. It’s just another chapter in the Web’s video standard wars.

Let’s start from the top: How can Google’s move be a step back for openness when both WebM and Theora are the only video codecs that actually are open source? H.264 while extremely popular is a proprietary format and its encumbered by patents held by MPEG LA, a patent holding company. Historically, MPEG LA hasn’t charged much for the use of H.264, but who’s to say that MPEG LA is always going to stay that generous?

Ed Bott thinks that Google may be moving into possible patent troubles by relying VP8/WebM. He’s right. Of course, they are. Welcome to technology post Bilski.

Today, as the patent lawsuit madness surrounding smartphones shows, technology innovation is starting to take a backseat to patent litigation. Even the open-source favorite Theora isn’t completely clear of patent issues.

World IPv6 Day has Facebook, Google & Yahoo Support

Yes, we all know we need to convert our networks and Web sites over to IPv6, but no one wants to be the first. Well, now the Internet Society, the non-profit organization supporting Internet standards, education, and policy-making, is trying to solve the problem for us by getting many major Internet Web powers such as Facebook, Google, and Yahoo! and important content delivery network (CDN) providers, including Akamai and Limelight Network to use IPv6 on June 8, 2011.

According to The Internet Society, “The goal of the Test Drive Day is to motivate organizations across the industry – Internet service providers, hardware makers, operating system vendors and web companies – to prepare their services for IPv6 to ensure a successful transition as IPv4 addresses run out.”

Today, only a few Web sites, ISPs, and CDNs support IPv6. Martin Levy, director of IPv6 strategy for Hurricane Electric, an IPv6 specialist that provides ISP backbone and co-location services, said today that there are only a handful of sites and CDNs that support IPv6. These include Google; Netflix, to a degree; Germany’s Heise Online; Facebook at ipv6.facebook.com; and Limelight.

Specifically, the Society hopes World IPv6 Day will “expose potential issues under controlled conditions and address them as soon as possible.

CPTN Holdings is still trying to buy Novell’s patents

When I first read a story that CPTN Holdings-a Microsoft-led group that also includes Apple, EMC, and Oracle–was no longer in the running to buy 882 of Novell’s patents, I knew the story couldn’t be right. Yes, the Open Source Initiative (OSI) had protested against the patent deal to the German Federal Cartel Office, but just because CPTN has withdrawn a filing to the Office didn’t mean that CPTN was giving up on the deal. Far from it.

I suspected that since Attachmate’s acquisition of Novell has been delayed by Attachmate needing more funds to seal the deal and Novell had to re-set the acquisition clock thanks to the Christmas holidays, that the closely-associated CPTN deal had run into similar problems. I was right.

Sources close to Novell told me that was indeed the case. The CPTN group will be re-filing to obtain the patents. Their plans haven’t changed a bit. A Microsoft representative confirmed that CPTN was still planning on buying the patents. The PR rep said, “This is a purely procedural step necessary to provide time to allow for review of the proposed transaction.”

Android vs. iPhone: The GPL Question

Well, now we know. You can’t sell software using the General Public License (GPL) on the Apple App Store& because it conflicts with its Terms of Service (ToS) . The popular VLC media player, was the first major GPLed software to be pulled from Apple’s App Store, it won’t be the last. But, what about Google’s Android Market? I asked the experts and they tell me that, in general, GPL developers can offer their wares on Android.

I asked Columbia Law School professor Eben Moglen and head of the Software Freedom Law Center (SFLC) about whether GPLv3 programs, as well software like VLC, which is under the GPLv2, would be restricted from Apple’s App Store, and he replied, “Yes. The problem isn’t in the license terms. The problem is that the Apple App Store ToS for people wanting to distribute through it require that each app sold (even at price zero) must be licensed for use on a single device only. Permissively-licensed FOSS can be transacted for in the App Store, because its license can be replaced by single- device-only terms. Copylefted software can’t be un-freely relicensed, so it can’t be transacted for there under Apple’s current ToS.”
