Google won't run all the Wave servers

In a recent story about how Google creatively destroys markets, I said that only Google will run the servers for Wave, its re-think of e-mail. I was wrong about that, as Google reps took pains to tell me. I want to set the record straight. What Google is doing with the Wave communications architecture is important enough that it merits its own story, not just a strikeout in the original.

Google has said it will "federate" Wave. That means it will make it possible for anyone to operate their own Wave server and have it communicate with other Wave servers. This is just how e-mail works today: Anyone can run an e-mail server that can send messages to and receive messages from any other e-mail system. The Internet routes messages from server to server.

In contrast, only Google runs the Gmail servers.

I was told that anyone will be able to "build their own Wave server without involvement from Google." That means corporations and governments will be able to deploy their own instances of Wave inside their secure firewalls if they like, and decide how or if they want to open up their servers to the outside world. For businesses with strict data retention and auditing requirements (e.g., all public companies, governmental agencies, health care businesses, etc.), this also means that they'll be able to write in software to meet their needs; or that other companies will be able to create and sell Wave servers. (If, that is, business gets behind Wave at all.)

However, sources familiar with the intricacies of building a real-time synchronization engine, which is what Wave is, tell me that it is incredibly challenging to make such a system work "at scale." Showing off a Wave demo is one thing. But a successful, well-performing, wide-scale rollout requires advanced technology that few companies have the chops to write, and it's hard to keep performance up as the size of the user community grows. This may be why the original planned release of Wave to developers outside Google has been delayed by several days.

Wave will be based on (and extend on) the existing messaging standard, XMPP (eXtensible Messaging and Presence Protocol). So a lot of Web developers will be able to get started quickly on writing Wave extensions and apps, as well as building their own servers to run Wave or back-end services for their Wave plug-ins.

Wave may represent new thinking about packaging real-time communication, but it's not based on 100 percent new or proprietary technology, so we might see some interesting third-party extensions to Wave very shortly after it starts rolling out to the public.

I stand by the rest of my story, especially my main thesis: Google destroys entrenched markets. That's not a bad thing, though. Especially when it comes to e-mail.

Google releases Google Wave demonstration video

For those who are having a little trouble understanding exactly what Google Wave is all about, seeing it in action might help you wrap your head around the concept.

Google has released video of Thursday's keynote speech at Google I/O in San Francisco, where the company publicly demonstrated Google Wave for the first time before about 4,000 developers. Google Wave is an ambitious, if incomplete, attempt to reinvent e-mail and Internet communication in general.

Developers are just starting to get their hands on Google Wave to try it out for themselves, but the public is not expected to get the same chance for several months. We hope to post a hands-on review ourselves in the coming days, but for now, check out the video if you'd like to see Google Wave in action. Be forewarned, it's long (90 minutes).






Mozilla testing near-final Firefox 3.5

Mozilla is close to releasing of its near-final version of Firefox 3.5, but the updated browser wasn't quite ready in time for a planned day of widespread testing.

Earlier this month, Mozilla set Friday to be Firefox 3.5 RC1 Test Day. But RC1, the first release candidate designed to be more stable than the earlier Firefox beta versions, wasn't finished for the occasion.

"Even though RC1 hasn't been released yet, the test day will still go on with the latest nightlies (nightly builds of Firefox based on the latest source code) which are practically RC1 minus some minor uplifts," said Aakash Desai of Mozilla's quality assurance team on Thursday. Mozilla has set up the Litmus program to encourage broad testing of its software.

RC1 is expected in a few weeks, spokeswoman Melissa Shapiro said Friday, though one developer told CNET News he hoped it would arrive in less than two.

The new version of Firefox began as version 3.1, a modest update. But a gradually expanding feature list led Mozilla to rename it 3.5 and release it months later than had been planned initially. In the meantime, Microsoft released Internet Explorer 8, Apple released a beta of Safari 4, and Google has released a rolling series of upgrades to its new Chrome browser.

Among the changes compared with the current Firefox 3.0.x versions are the faster TraceMonkey engine for running Web sites' JavaScript programs; support for tags to describe audio and video content the way images have been available for years; the private browsing mode for leaving no traces on your computer while surfing; support for geolocation technology to let permitted applications know the user's location; built-in JSON (JavaScript Object Notation) technology for exchanging data between servers and browsers; and support for the Web Workers standard for letting a browser perform processing in the background without holding back a Web application's user interface.

Turkish hackers breached U.S. Army servers

How secure the U.S. ArmyWeb server? maybe this story can answer that question.

A group of hackers based in Turkey penetrated two U.S. Army Web servers and redirected traffic from those Web sites to other pages, including one with anti-American and anti-Israeli messages, according to a report in InformationWeek.

"Mosted", that the name of the group, breached a server at the Army's McAlester Ammunition Plant in Oklahoma on January 26 and a server at the U.S. Army Corps of Engineers' Transatlantic Center in Winchester, Va., on September 19, 2007, the report said.

Investigators believe an SQL injection attack was used to exploit a vulnerability in Microsoft's SQL Server database in order to gain access to the servers.

It is unclear whether any sensitive information was accessed, according to the report.

Search warrants have been served on Microsoft, Yahoo, Google, and other ISPs and e-mail providers, while a criminal investigation is underway at the Defense Department, the U.S. Army's Judge Advocate General's Office, and the Computer Emergency Response Team, InformationWeek reported.

The same group defaced the United Nations Web site in 2007, also using a SQL injection attack.

Microsoft confirms Zune HD coming this fall

Microsoft on Tuesday confirmed its plans to take on the iPod Touch with a new, touch-screen Zune that will be able to surf the Web, play high-definition movies, and tune in to digital radio.

The Zune HD, which will be available in the U.S. only starting this fall, features an HD Radio tuner as well as an organic light-emitting diode (OLED) touch screen, Microsoft said. It is based on Windows CE and will use a version of Internet Explorer customized for its touch screen, Microsoft said.

The software maker did not announce pricing or capacity, though it said the device will use flash memory and attempt to take on Apple's high-end iPod models.

"This device is created to go head to head with the iPod Touch," Chris Stephenson, general manager of global marketing for Microsoft Zune, said in a telephone interview on Tuesday. Zune buyers will also be able to play HD content on their TVs via a dock, Microsoft said.

The software maker also said that at next week's E3 trade show in Los Angeles it will announce details on a new Zune-branded video service for the Xbox that will replace the current Xbox Live marketplace for TV and movies. The company didn't announce details or specifically say that content will be playable on both Zunes and the Xbox.

Currently videos purchased via the Xbox can't be played on a Zune, although both stores use a similar back-end infrastructure to serve up content. Over time, Stephenson said the goal is to move toward a world in which content purchased once can be played on a variety of devices.

Microsoft plans to offer the new Zune video service in a number of European markets, in addition to North America.

s for the Zune HD, Microsoft is doubling down on its bet on a radio tuner as a distinguishing feature. Stephenson noted that the current Zune's FM radio is its second most popular selling point. Adding support for HD Radio, a free over-the-air digital radio technology, represents both a risk and opportunity.

"It's really one of the first portable HD radio receivers out there," Stephenson said. "It's going to be important for us to communicate the value of HD Radio since it is a fairly nascent technology."

One of the big unanswered questions is what sort of gaming abilities the Zune HD will have. There has been speculation on the topic, but Microsoft refused to comment ahead of E3 saying it had no details to share at this time.

Microsoft plans to continue selling its hard drive-based model, which will have a software QWERTY keyboard, but said it plans to eventually discontinue its other flash models in favor of the Zune HD.

"Expect to see the Zune HD...become the definitive Zune product going forward," Stephenson said. "You will continue to see the hard drive product in the market. (The Zune HD) will take over from existing flash devices."

Although Microsoft has said it isn't building a ZunePhone, the company does want to be able to offer its Zune service on phones. However, Stephenson said that is a longer-term goal that will take at least until next year to fulfill.

"This is enough work for us this year," he said. "Going forward, Zune will start to surface on multiple platforms across the ecosystem. Expect to see it pop up in many different places."

Zune HD will be a music player, not a super-device

After months of increasingly wild rumors, CNET's Ina Fried got the official scoop yesterday: Microsoft is indeed releasing the Zune HD this fall. The device will feature an OLED touch screen, high-definition video output (with an optional add-on), a version of Internet Explorer (it sounds similar to the version planned for Windows Mobile 6.5, which uses the core IE6 engine but adds Flash support, as well as some technology from IE8 to better support JavaScript), and HD Radio.

I spoke to the Zune marketing team this morning, and they didn't have much to say beyond those points. In fact, they weren't originally planning on saying anything until later this summer, but felt they needed to set expectations for Zune customers in light of all the rumors.

Here's why: the Zune HD isn't going to be the super-device that some geeks had been hoping for. It will play games--just like today's Zunes, which ship with a couple simple games--but it won't be a full-fledged gaming device like the Sony PlayStation Portable or Nintendo DS. It won't have its own application store, although Microsoft hinted it might connect to the forthcoming Windows Marketplace for Mobile, which could let third-party apps like Facebook and Pandora find a home on the device. It won't feature WiMax connectivity, although that might be planned for a future touch-screen phone with a similar form factor.

In other words, this is Zune 3.0, a music-focused device with a nice touch screen. It'll support video and apps, sure, but the team is focusing on improving the music-playback experience--think album art, more detailed artist pages with images, perhaps lyrics or video content.

Will these features be enough to get users to choose a Zune HD instead of an iPod Touch? The main difference seems to be HD Radio. I believe Microsoft when they say FM radio is the Zune's second-most important selling point, but Zune users are a very small portion of the overall MP3 player market--the tens of millions of users who bought an iPod didn't care about radio. There may be some other killer features we don't yet know about, and there's always the Zune Pass to consider--a great deal at $14.99 a month for unlimited streams and 10 permanent downloads--but I think the uphill battle against Apple will continue.

As far as the other half of the news goes, it's been clear for some time that Microsoft was getting ready to integrate the Zune Marketplace into Xbox Live. The company will have more details to show off next week at E3, so I'll save further comment until I see what they've got.

Data backup service leads to recovery of stolen laptop

Using a data backup program helps recover lost data but can also help get a stolen laptop back--if you're lucky.

A Berkeley, Calif., man recently recovered his stolen laptop after seeing photos the thief took of himself with the built-in camera via his Internet-based data backup program.

That's according to a police officer's article in an e-mail newsletter from Berkeley City Councilmember Susan Wengraf that was posted to the Web by open-source advocate Bruce Perens.

It all started on May 5, when the victim left his laptop in the back seat of his car (tsk tsk). Two hours later, the thief smashed the car window and grabbed the computer. It's not clear what else was done with the laptop, but the big break in the case came when the laptop owner later spotted the self-portrait photos of the thief on the storage service Web site.

Detectives working the case were shown the photos and recognized the man, who had been released from jail earlier in the year. They noticed that in the photos he appeared to be in a motel room and began trying to track down the IP address used by the laptop hoping that it would lead to the motel.

Before that could be accomplished, however, the detectives spotted the man getting into a car in a motel parking lot in Oakland and arrested him. In his car and the motel room they found the laptop along with stolen property from other auto burglaries.

Obama expected to announce cybersecurity revamp, 'cyber czar'

On Friday, the United States President, Barack Obama xpected to unveil his administration's plans to deal with cybersecurity threats to federal agencies and the private sector, including the creation of a White House "cyber czar."

It's not yet clear who that person will be, or even whether Obama will name someone during his announcement. As part of a political compromise, the new position is expected to be folded into both the National Security Council and National Economic Council.

The announcement, which is scheduled to take place at 10:55 a.m. ET in the White House's East Room, caps years of criticism of the Department of Homeland Security's efforts and months of speculation about what form the replacement cybersecurity bureaucracy will take.

"It provides the president with recommendations for a White House organizational structure that can effectively address cyberspace-related issues," Melissa Hathaway, acting cyberspace director for the White House's National Security and Homeland Security councils, said recently.

No bureaucratic mandate will satisfy everyone: Security hawks would like the "czar" to have authority -- which may mean new laws -- to direct both federal agencies and private businesses on cybersecurity matters. Business representatives, on the other hand, like the potential for increased high-level attention but remain wary of mandates from Washington.

In February, Obama ordered a 60-day review of the federal government's cybersecurity efforts, and appointed Hathaway -- who had worked for the director of national intelligence in the Bush administration -- to lead it. Two months later, Hathaway announced the report had been submitted to the president along with recommendations; it's expected to be made public on Friday.

Earlier this week, the White House offered a hint about how the restructuring would proceed, and indicated that the "czar" would not report directly to the president. Obama's statement on Tuesday said the national security and homeland security staff would be integrated and new positions inside the National Security Council and Homeland Security Council would "deal with new and emerging 21st Century challenges associated with cybersecurity."

In addition, The New York Times reported on Friday that the Pentagon is preparing a new military command for cyberspace that would operate in parallel with the civilian effort that Obama is expected to announce. He is "expected to sign a classified order in coming weeks that will create the military cybercommand" and recognize "that the United States already has a growing number of computer weapons in its arsenal and must prepare strategies for their use," the newspaper said.

Bureaucratic roadblocks
The origin of many of the Feds' cybersecurity headaches can be traced back to the process that led to the creation of the Department of Homeland Security nearly seven years ago. Politicians in Washington, D.C. decided to decided to glue together a medley of federal agencies to create a massive bureaucracy that would, as one of its new goals, provide a better focus on cybersecurity.

"The department will gather and focus all our efforts to face the challenge of cyberterrorism," President Bush said when signing the 500-or-so-page bill into law in November 2002. "This department will be charged with encouraging research on new technologies that can detect these threats in time to prevent an attack."

Some tasks might benefit from centralization in one of the world's largest bureaucracies. But it soon became evident that cybersecurity was not one of them. By 2005, government auditors concluded that the department failed to live up to its cybersecurity responsibilities and may be "unprepared" for emergencies; as recently as last fall, DHS Secretary Michael Chertoff said his agency needed to develop a plan to respond to a "cybercrisis."

That led some outside groups to argue that cybersecurity efforts should be taken over by the National Security Agency, which already is responsible for protecting government computers through its "information assurance" arm, or perhaps the White House staff.

Lending an unusual spice to what would normally be a internecine power struggle conducted in secret was March's resignation of Rod Beckström, director of Homeland Security's National Cybersecurity Center. In his farewell letter, Beckström blasted what he said was an NSA power grab, saying the secretive military agency "effectively controls DHS cyber efforts through detailees, technology insertions."

The week before Beckström's resignation, Director of National Intelligence Admiral Dennis Blair suggested to a House committee that the NSA was ready for the job, saying "there are some wizards out there at Fort Meade." But a few weeks later, after a congressional hearing that was hardly enthusiastic about the idea, NSA director Keith Alexander denied his agency had any interest in the job.

If any of this sounds familiar, it should. About a year after President George W. Bush took office, his administration announced a highly-anticipated, 76-page document called the "National Strategy to Secure Cyberspace" (PDF). Few of its bullet points calling for immediate "response" have been enacted; even fewer people remember what they were.

MTV's 'Alexa Chung' tunes in Social Media (Facebook, Twitter)

This story is from Caroline McCarthy, a CNET News staff writer, its about the TV Industry and the corellation with social media on the internet, like Facebook and Twitter.

Can you really take everything that's going on with movies, TV shows, music, Internet memes, and social media, and wrangle it all into an hour of live television? MTV believes it can--with some help from Twitter, Facebook, and a quirky British model-turned-TV-host named Alexa Chung.

The pop-culture cable network's new daily talk show, titled "It's On with Alexa Chung," premieres at noon on June 15 and expectations are high. The show is taking over the time slot once held by "Total Request Live," or "TRL," the music video countdown show that more or less defined MTV--and in turn, mainstream youth culture--in the late '90s and early '00s. Chung, 25, is a British import who's already solidified a reputation as a quirky TV host across the pond, but is largely unknown in the U.S.

But it's the dual partnerships that MTV has inked with Facebook and Twitter that are really generating buzz. There will be on-screen "tweets," content sourced from Facebook profiles and fan pages, audience contribution from polls to remixed YouTube videos, and round-the-clock updates from Chung's own Twitter account. If it's all done right, "Alexa Chung" could be both a milestone in the convergence between TV and the Web, and a fresh infusion of innovation for a TV network that many say was shooting itself in the foot for not catching onto the social media craze earlier.

"The hope is that (social media) will just be something that is like the air that the show breathes on," said Dave Sirulnick, executive vice president of news and broadcast at MTV. "I think our audience, they'll expect this from us. They're going to expect us to talk to them the way they talk to each other. It's the way they experience the world, you know--it would be odd for us to mount this project, put this up on the air, and not have that happen, you know, because our audience, I don't think they look at it as something that is all new. This is just what they've grown up with."

A decade ago, if you wanted to get a message on MTV, your best bet was probably to write it on a poster and join the cheering crowds outside the network's New York studio during a "TRL" taping, hoping to make your way into the scope of the cameras sweeping overhead. Or if you were really lucky, you could call in and have your telephoned questions asked to celebrity guests on-air.

"In the old days our connection to the outside world on 'TRL' was one person on a phone," said executive producer Tim Healy. "Now with this new show it's definitely increased the scope."

MTV canceled "TRL" earlier this year--some would say belatedly. The network's reputation as a hub of pop-culture influence had long since started to fade: New music was being discovered on MySpace pages and niche music blogs. Popular clips from last night's TV shows were swapped via YouTube and Hulu links in instant messages and posts on Facebook profiles. Youth culture had grown segmented and fragmented with the mass availability of niche "long-tail" content on the Web, and social media had thrown out everyone's old notions of shelf lives--a 10-year-old music video can become an overnight hit on YouTube if enough people start telling their friends about it, whereas fresh Internet fads can be eclipsed and forgotten faster than ever. It seemed that when it came to encapsulating the cool-kid zeitgeist, a live TV show just couldn't cut it in the digital age.

With "Alexa Chung," MTV is making a totally different show. The iconic "TRL" set has been converted into something that looks like a loft apartment, with the studio audience scattered around like party guests. There will be no countdown--rather, a talk show format inspired in part by late-night programming, with topics ranging from movies and music to the latest YouTube sensations (whom Chung plans to regularly bring onto the set to see if their singing, dancing, or other oddball talents are for real). And there will be no screaming crowds in Times Square. Instead, there will be tweets.

The tweet smell of success?
"I think the genius of Twitter is that it's in the second. Not even the moment, it's right now," Sirulnick said. "Instant feedback from the audience, from what's going on, will be on-screen. Whether it's a persistent on-screen feed is something we're toying with right now. We haven't entirely decided."

This won't be MTV's first experiment with Twitter. Nearly two years ago, the network started a Twitter account for the "moon man," the mascot for its annual Video Music Awards, as a promotion for the ceremony. It went largely unnoticed: In the summer of 2007, Twitter was hardly a household term.

But after unofficial celebrity endorsements and an appearance on Oprah hurtled Twitter into the mainstream earlier this year, the situation is very different. A firestorm of gossip ensued last week when a report in Variety implied that the company was developing a reality TV series. The rumors got so out of hand that co-founder Biz Stone posted a clarification on the company's official blog: "We're not making a TV show," he wrote.

"That was very frustrating and unfortunate, and a misrepresentation of all sorts of things," Chloe Sladden, Twitter's director of business development for global broadcast and news media, told CNET News several days later.

As it turns out, the Variety report detailed one of a number of partnerships that Twitter is working on with media and entertainment companies. That's Sladden's specialty: she was hired by Twitter this spring, after she spent several years working at Current, the edgy cable news channel co-founded by former vice president Al Gore. While at Current, Sladden worked with Twitter to help supplement its 2008 election coverage with on-screen tweets. Now at Twitter full-time, she's helping media outlets--including, but not limited to MTV--integrate tweets, Twitter searches, trending topics, and the like into their broadcasts.

There's no financial transaction involved in the "Alexa Chung" deal, Sladden said, and that's the way Twitter intends it to be.

"We're trying to unlock the true potential of Twitter, and a lot of our strategy has been to let other folks build a lot of cool stuff on top of Twitter. So the model here is much like the application developers," she explained. When it comes to Twitter's media partnerships, "think of this as a creative API."

MTV's partnership with Facebook is a little more formal, and a little more out-of-the-ordinary for both the social network and MTV. "Whenever they have a celebrity guest, they're exclusively featuring Facebook's presence for that celebrity," said Randi Zuckerberg, who heads up marketing at Facebook (and, yes, is founder Mark Zuckerberg's sister). "Which is really cool. The majority of celebrities have Facebook fan pages right now, with thousands or millions of fans." There will also, of course, be a "fan page" for the show itself, where viewers can submit questions to celebrity guests, vote on which songs they want bands to play when they appear live, and provide general feedback.

But in addition to celebrity fan pages, viewers' own Facebook profile content might pop up on the show. "People in the studio audience will have the opportunity to temporarily 'friend' some of the producers," Zuckerberg said. "Basically, they'll 'friend' them for about two hours, the duration of the show, and then they're going to encourage people to do mobile uploads during the show, mobile status updates, mobile photos, et cetera." For those who aren't in the studio audience, questions for the celebrity guests can be accompanied by Facebook photos or other content.

It's still a touchy issue, considering that a lot of Facebook profile content still isn't public, and many people wouldn't want their party photos splashed all over MTV without very explicit permission. And it's a sharp turn from Facebook's erstwhile hardline attitude of keeping everything behind a login wall, which is why representatives from both companies say that the use of Facebook content on TV will be given the kid-glove treatment.

"Everything's going to be signed off on by the people who are asking the questions," Sirulnick said, adding that MTV has been working with Facebook to finalize and streamline consent procedures. "We're not going to be exposing anybody who has not explicitly agreed to have their material on television. It's important to us, it's important to the audience, it's fair. It's important to Facebook."

MTV + Facebook = ad potential
Unlike the Twitter partnership, this isn't a money-free deal. MTV and Facebook have assembled a joint advertising sales team to sell sponsorship packages that encompass both TV spots and social-media ads.

"A sponsor can have placement on the show, commercials or in-show integration, and also integration on Facebook," explained Randi Zuckerberg, who previously helped orchestrate a partnership with broadcast network ABC during the presidential debates last year. "So, they can do an event RSVP ad for their participation in episodes they're in. They can be integrated into the Facebook page for Alexa's show. There's a lot of great things that they can target to fans of a certain celebrity. We're really going out together and really involving sponsors on both Facebook and TV."

This is big news for the nascent social-network advertising market. Plenty of companies aren't yet comfortable putting ads on the likes of Facebook, having heard the rampant belief that returns aren't good.

MTV's Sirulnick said he sees the joint ad sales strategy as a way for longstanding MTV advertisers to take the plunge into social media, for example, "if Sponsor X is a sponsor of MTV, and has been looking to get into the social-networking space, and has been looking for a window in." But he said that MTV will keep the profits from ads on its own properties, and Facebook will do the same for its site. "The MTV and the Facebook sales teams are out there jointly putting together packages for sales, but it's not a revenue share."

Not everyone in digital media is sure that this hybrid of broadcast television and user-generated social-network content will work.

"As a device every now and then it's OK. When it's persistent, it's annoying," said Jim Louderback, CEO of Web video production company Revision3, when asked about the idea of bringing Twitter and Facebook to broadcast television. "Mixing two mediums together like that doesn't work. You lose what makes each medium work really well, and that's why television on the Web is different from Web TV. That's why WebTV from Microsoft didn't work."

That said, MTV executives say that they're shaping and tweaking "It's On with Alexa Chung" up to the moment it airs, and will continue doing so even after the June 15 debut. The network is clearly excited at this chance to reinvent its brand--and to keep reinventing it, ideally preventing it from growing stale the way "TRL" did.

"It's going to be something that every day we're trying to come up with new things (for)," Sirulnick said. "The folks at Facebook are very excited about this, the folks at Twitter are very excited about this, and the good news is that they get us, they get the audience, they know what works really well on their site. And so it's much more, We're just talking all the time."

Alexa Chung herself appears to be equally excited.

"First guests confirmed for my new show. SO GREAT," she posted to her Twitter account on Wednesday. "America can you watch me please?? Cos my mum doesn't live here."
