AOL upgrades messenger, integrates social network

NEW YORK (Reuters) - AOL said on Wednesday it will launch an upgrade to its instant messenger software with new features that let users track some of the online activities of their friends.

The debut of AOL Instant Messenger, or AIM 6.0, lets users link to "Really Simple Syndication," or RSS, feeds of their friends that keeps track of friends who upload videos or posts pictures to sites such as Google Inc.'s YouTube or Yahoo Inc.'s Flickr.

The upgrade, which also provides easier-to-find links to AOL's own take on social networks, popularised by rival service MySpace, comes amid a restructuring of AOL announced this summer.

Eying the surge in online advertising sales growth, the online unit of the world's biggest media company Time Warner Inc. decided to give away most of its services for free. It continues to operate a dial-up Internet service, but no longer markets the service.

Early signs of progress came at the end of the third quarter when it reported a 46 percent growth in online ad revenue.

"This version (of AIM), and a lot of what we are doing in AIM Pages, is extending the user-generated communications platform on their terms with what people care about," AOL Vice President Marcien Jenckes said.

Other features of the upgrade include the ability to leave messages for friends even if they have logged off and a feature that lets users save text logs of their conversation.

AIM users can also add up to 1,000 friends on their buddy list.

More than 42 million messaging users are on the AOL Network. Over 30 million of these use AIM.

Microsoft First To Offer Set-top HD Video Downloads

It's the future, you know? There'll come a time where you don't have to make sure you're sat in front of the television at the right time, on the right day, to watch your favourite programs. And you won't have to remember to call in and rent that movie on your way home from the office.

You'll just sit down in front of the TV - and by that it point, it won't be the hulking, cathode-ray powered brute you're likely so comfortable with now; it'll be something far more svelte and slim line - pick which film or show you'd like to watch, and be basked in the crisp, high definition loveliness that follows.

At least, that's the future according to Microsoft. This week, they announced that they would be offering a new set of video downloads to their Xbox 360 console.

The Xbox 360, the world's first HD games console, (unless you listen to Sony) has offered video downloads since it's launch almost a year ago. Trailers for both games and movies, along with a variety of music videos have been accessible since launch using Microsoft's Xbox Live service in varying resolutions, offering gamers the chance to sample some true high definition video material.

That's to be expanded into a full-blown video download service, featuring movies and TV shows. Blockbusters like Superman Returns, The Matrix, and Batman Returns will be available as HD downloads. Episodes of Robot Chicken and Aqua Teen Hunger Force from The Cartoon Network will be available, amongst other, more varied TV shows like CSI, or Jericho.

It's an unsurprising move, but one that is likely to cause numerous headaches for Microsoft's competitors, the most obvious of which is Sony. The creators of the PS3 have an awful lot riding on their imminent yet troubled launch, and haven't — so far — announced any specifics for film and TV downloads on their system. Sony's machine contains Blu-ray technology, their ticket to HD multimedia content, and it's unlikely that they'd do anything to dilute the format's potential.

Sony have publicly criticized Microsoft's plans, reminding potential buyers — and presumably existing owners — that they'll be needing Microsoft's more expensive bundle if they're to enjoy the video download service. Both versions of Sony's PS3 console contain internal disk drives for content storage; the Core Xbox 360 system does not.

Sony's argument is that a future video download service for the PS3 will be available to all customers, not just those with more money to spend on their console. It's worth noting that the lowest price PS3 system retails for $500, while Microsoft's high-end premium bundle costs $400.

Aside from angering Microsoft's gaming nemesis, the move is certain to raise a few eyebrows at Apple's headquarters. Steve Jobs demonstrated their (codename) iTV system during a recent keynote speech, a set-top device that aims to allow video and audio streaming from other household computers, and the Internet. The iTV will likely be cheaper, quieter, and less power hungry than console equivalents, but — unless Steve has a few more tricks up his sleeve, a la the recent games for the iPod devices — it lacks the gaming capabilities that are the PS3 and 360's reason for being.

Apple have close ties with Google and, as a result, YouTube, which might mean their iTV device holds appeal for a different demographic to Microsoft and Sony's gaming heavyweights. Microsoft may leverage their MSN Soapbox service, a very similar beast to YouTube and Google Video, for the 360, but no plans have yet been announced to this end. Regardless, Soapbox hasn't captured the public's affections in the same way as YouTube.

Microsoft still has a few issues to overcome, aside from their competitors. The current, premium edition of the Xbox 360 has, theoretically, 20 gigabytes of available storage space. Theoretically, because a chunk of the drive is used for backwards compatibility with Xbox games, saves and downloadable content for Xbox 360 games, and can be used to improve performance during particularly intensive games; game data is copied to the drive, increasing the speed of a repeat use of a texture, or sound. Ultimately, this doesn't leave an enormous amount of space for downloads.

Films will be downloaded, watched, and deleted - at least, initially. Microsoft will allow the viewer 14 days to watch a "rental", after which it's removed from the drive. TV, however, is yours to keep. Given that most TV series stretch to 22 - 24 episodes, and each 60 minute show is claimed to take up 1 gigabyte of space, it's unlikely that a whole series could be stored on the existing drive. So, it stands to reason that a bigger hard disk drive would be released for the system.

The second, significant issue, is bandwidth. In my experience, Xbox Live isn't as fast during downloads as the "regular" Internet. It takes far longer to download 1 gigabyte of data on Xbox Live, than it does to download 1 gigabyte of data on my PC. Maybe my ISP/Xbox/Router/Wind turbines are configured incorrectly, but it's something I've read complaints about on Internet forums too.

Microsoft needs to ensure that the bandwidth is in place to support their new multimedia vision. They also need to ensure that it's as easy to achieve the required download speeds on your Xbox as it is on your PC.

Configuration issues aside, there's also the issue of time. Full length movies are likely to be around 5 gigabytes in size - a file that would take quite a while to download using today's internet connections. And while you don't have to sit and watch the download immediately, if the mood takes you and you have to watch a movie at this precise moment, a tedious wait in a download queue is the last thing you want.

In addition to this, Microsoft must launch the service outside of the US. It's not yet known whether the BBC or other broadcasters are interested in coming on board, and it's these deals that will be fundamental to Microsoft's success.

Regardless of the speculation, mud-slinging, and general grumpiness, the fact remains that Microsoft got there first. Again. The time for Sony to put their money where their mouth is fast approaches, a challenging launch period where all eyes will be upon the newcomer.

Microsoft can approach the holiday season with high stock levels, a raft of enticing multimedia content online, and some killer apps - built with the benefit of developer's increased familiarity with the system. Sony, on the other hand, has an eager fan base, arguably superior technology, and Blu-ray in their corner.

Sony's film and TV connections may well put them in a position to trump Microsoft's offering, given time, and Apple have proved in the past that they're not to be underestimated in this arena; iTunes has been a success where many have failed. Microsoft is unlikely to be the only source of on-demand HD content for very long.

The battle lines are drawn; intentions have been stated, and the fight is about to begin. It'll be an interesting one to watch.

Attacks, Flaw Reports Mar IE 7 Release

Microsoft released a major update of its Internet Explorer Web browser this week, but the red-letter occasion was stained by reports of anti-virus miscues, phishing attacks and what turned out to be untrue reports that the new product contains previously documented security flaws.
 
First came a run of junk e-mail claiming to be from Microsoft that tried to get recipients to click on a link and download the latest version of IE (the link, as you may have already guessed, installs a Trojan horse program that opens a back door for hackers on infected PCs.)
 
Then came reports of a vulnerability in IE 7 that was somehow carried over from the older IE 5.5 version. Vulnerability watcher Secunia said it developed a proof-of-concept attack using the bug that could allow a maliciously crafted Web site to steal any data a user may enter at a separate Web site.
 
Not exactly, Microsoft responded. In a post to its Security Response Blog Thursday evening, Microsoft said the problem is related to a component of Outlook Express, the default e-mail client installed on Windows PCs.
 
"These reports are technically inaccurate: the issue concerned in these reports is not in Internet Explorer 7 (or any other version) at all. Rather, it is in a different Windows component, specifically a component in Outlook Express. While these reports use Internet Explorer as a vector the vulnerability itself is in Outlook Express," the company said.
 
Microsoft urged users to temporarily disable anti-virus and anti-spyware software before installing the program, noting that IE 7 makes a large number of changes to the Windows registry, which the table of contents on Windows that determines which programs should be loaded when Windows or certain user accounts are started up. Some security software will block those changes.
 
Finally, some of the top tech blogs have been less than impressed with IE 7, according to a round-up at USA Today. Computerworld also has a decent compilation of IE 7 coverage. I have traditionally been hard on Microsoft with respect to security in IE, and I don't think undeservedly so, either. I'm afraid it's going to take some time for Microsoft to win back some credibility on browser security (and plain old functionality) in the tech community.
 
For my part, I was asked several times in today's Security Fix Live Web chat what I thought about IE 7. In retrospect, my response the final time I answered was probably below-the-belt, but it gets to the point I was just trying to make about trust.
 
A reader asked: "Why should I bother upgrading to IE 7 since Firefox is a superior browser? IE6 works fine for the limited amount of usage I need."
 
My response: "Would you leave a loaded gun sitting on the table in a house with toddlers? Hopefully not. Okay, that's a little harsh, but think of it this way: lots of things on Windows use IE's built in rendering engine, and if you have a more secure version of the browser available, why not switch to it? This advice is especially aimed at households where more than one person uses the PC. "
 
Final note: If you want to install IE 7, keep in mind that it requires you to validate your copy of Windows.

Transmeta Files Suit Against Intel

SAN JOSE, Calif. — Despite bailing out of the x86-based microprocessor business last year, Transmeta Corp. Wednesday (Oct. 11) announced that it has filed a lawsuit against Intel Corp.
The suit, filed in the U.S. District Court for the District of Delaware, alleges that Intel infringed upon ten of Transmeta's patents. The patents cover computer architecture and power efficiency technologies, according to Transmeta (Santa Clara, Calif.).
The complaint charges that Intel has infringed and is infringing Transmeta's patents by making and selling a variety of microprocessor products, including at least Intel's Pentium III, Pentium 4, Pentium M, Core and Core 2 product lines.
The complaint requests an injunction against Intel's continuing sales of infringing products as well as monetary damages, including reasonable royalties on infringing products, treble damages and attorneys' fees.
"Transmeta has developed a strong portfolio of intellectual property rights to capture and protect our proud legacy of developing advanced computing and microprocessor technologies,'' said John O'Hara Horsley, executive vice president and general counsel at Transmeta, in a statement.
"Intel has acknowledged that Transmeta has been an innovative spur to some of Intel's own development efforts, roadmap decisions and new product successes,'' he said. ''At the same time, Intel has practiced multiple Transmeta inventions in its major microprocessor product lines. After endeavoring to negotiate with Intel for fair compensation for the continued use of our intellectual property, we have concluded that we must turn to the judicial system to be fairly compensated for our inventions."
Last year, Transmeta laid off 67 employees in a restructuring plan aimed to focus more heavily on IP and the phase out its less profitable processors.

Most used cell phones and PDAs contain personal or business information that their former owners never got around to deleting.

 

Most used cell phones and PDAs contain personal or business information that their former owners never got around to deleting.

Most used cell phones and PDAs contain personal information that their former owners neglected to adequately delete, according to security company Trust Digital.

Trust Digital examined a small sample of used phones and PDAs purchased from sellers on eBay and recovered data from nine out of 10 of the devices.

"The file system on your cell phone or PDA is just like the one on your PC's hard drive," says Norm Laudermilch, the CTO at Trust Digital who restored the data. "If you delete a file, you're not really overwriting the data. All it's doing is changing the index of the file system or the file's pointers."

That makes salvaging data from discarded devices a snap, Laudermilch says. "It's really very simple. There are free tools on the Internet, as well as commercial tools that can resurrect data. We wrote our own little tool, about 30 lines of code."

Among the data that Laudermilch restored were credit card account numbers, sensitive chat logs, business E-mails about contract negotiations, and computer passwords.

Because phone and PDA data is stored in flash memory, it's retained even if the device's battery is drained or removed. To delete flash memory data, users have to do a "hard reset," which returns the hardware to its factory-fresh condition. Each phone and PDA maker uses a different hard reset procedure; some, in fact, can only be carried out by a technician or after users contact the phone service's help desk.

Phones and PDAs aren't the only electronic gear that isn't properly wiped before being tossed or sold. Studies of the contents of used hard drives have found similar results: a wealth of data, some of it confidential or personal.

Trust Digital recommends that users secure cell phones and PDAs using passwords to lock out casual snooping in case the devices are lost.
