You May Have To Jump Through Hoops Microsoft warned developers preparing to download the new Beta 2 release of Internet Explorer 8 that under certain conditions those who have already installed IE8 Beta 1 cannot revert to older iterations of the browser.
<p>
For Windows XP users with IE8 Beta 1 already installed, Windows XP Service Pack 3 and IE8 Beta 2 would become permanent, said Jane Maliouta, the deployment product manager for IE8 at Microsoft. "You will still be able to upgrade to later IE8 builds as they become available, but you won't be able to uninstall them," she said.
<p>
<subhead>
Incompatibility Issues
</subhead>
<p>
Developers will need to be careful because IE8 Beta 2 will not work with several key services, applications and add-on programs, including certain versions of the Google Toolbar, RealPlayer and Skype, and is even incompatible with Microsoft products and services, such as Visual Studio .NET and Windows Live Mail. IE8 Beta 2 users also are currently unable to view movies on demand from Netflix, though Microsoft said the two companies are working to resolve the compatibility issue as quickly as possible.
<p>
Maliouta strongly encouraged those who have already downloaded IE8 Beta 1 to follow several steps before installing the new Beta 2 version. First uninstall the Beta 1 version and SP3 for Windows XP, followed by reinstalling SP3, and only then install IE8 Beta 2.
<p>
"If you have IE8 Beta 1 installed, the IE8 installer will automatically uninstall any earlier versions and then install the latest version of IE8 Beta 2 for you," Maliouta said. "You will be prompted to reboot twice. The first reboot is to remove IE8 Beta 1 from your machine and the second one to complete the IE8 Beta 2 installation."
<p>
According to Microsoft, IE8 Beta 1 was only intended for use by developers. Consumers running Windows XP need not worry about downloading IE8... http://www.sci-tech-today.com/story.xhtml?story_id=61616 http://www.sci-tech-today.com/story.xhtml?story_id=61616 Fri, 29 Aug 2008 13:30:08 -0500 Speculation Focuses on iPhone Tethering Approval Having banned from its App Store an application that turned an iPhone 3G into a wireless modem, is Apple ready to enable just such an application itself?
<p>
That's the rumor based on an e-mail response allegedly from Apple CEO Steve Jobs to an inquiring user. The questioner forwarded the response to the Gizmodo blog, which posted the question and Jobs' purported response.
<p>
The question: Why, since AT&T offers a plan by which users can pay an extra $30 to tether their laptops to their BlackBerry, don't Apple and AT&T offer a similar plan for iPhone 3G users?
<p>
The response: "We agree, and are discussing it with ATT." The message is signed "Steve" and includes the familiar tag, "Sent from my iPhone."
<p>
<subhead>E-Mail Legit?</subhead>
<p>
Gizmodo thinks the response is "legitimate-looking," but concedes "that 'Sent from my iPhone' kicker either makes this e-mail completely legitimate or illegitimate." On the other hand, Wired News engaged in a little grammatical sleuthing, noting that a message, purportedly from Jobs, posted on the MacRumors site contained a similar construction.
<p>
"We are working on some bugs which affect around two percent of the iPhones shipped, and hope to have a software update soon," the message read. Wired points out that both messages incorrectly use a comma before the "and." (A comma is appropriate to separate independent clauses; in both cases the phrases after the comma are dependent clauses.)
<p>
"I don't mean to draw a conclusion based on this nitpicky observation, but I just thought it'd be interesting to point out," Wired writer Brian Chen pointed out.
<p>
<subhead>AT&T Terms of Service</subhead>
<p>
Any tethering application would require a change to AT&T's terms of service. Those terms state: "Furthermore, plans (unless specifically designated for tethering usage) cannot be used for any applications that tether the device (through use of, including without limitation, connection kits, other phone/PDA-to-computer... http://www.sci-tech-today.com/story.xhtml?story_id=61615 http://www.sci-tech-today.com/story.xhtml?story_id=61615 Fri, 29 Aug 2008 13:30:31 -0500 Yahoo Will End Mash To Start a New Social Service Yahoo plans to smash Mash, just one year after launching the new profile service. Yahoo describes Mash as a new approach to users' profiles that brings people together and keeps things interesting.
<p>
Mash users are being told that Mash will close on Sept. 29. The company plans to consolidate what it has learned with Mash into a new profile experience.
<p>
"We launched Mash as an experimental profile service with the goal of providing an interactive and social way of connecting with others," said Yahoo spokesperson Devon Corvasce. "Yahoo has announced we will soon be launching a new profile experience (an upgrade to profiles.yahoo.com) to work across the network, in the effort to make all of Yahoo more social."
<p>
Asked when the new service would launch, Corvasce said, "At this time, we are not publicly discussing the launch date of the new profile experience. You can look forward to seeing it in coming months."
<p>
<subhead>Testing the Social Waters</subhead>
<p>
Yahoo first began testing the Mash service is September 2007, making its foray into social networking. Yahoo offered the service to selected people outside of Yahoo's walls. Some observers speculated Yahoo offered the beta service after its expected purchase of Facebook failed.
<p>
Mash includes similar features to Facebook, MySpace, and My Yahoo. Mash users are able to create and customize a profile by filling Web pages with information, add modules such as photos and Web games, and add applications such as Flickr RSS, Common Friends, Asteroids, PimpMyPet, Kaleidescope and more. Friends are also able to make changes to the user's page.
<p>
The intent was to extend features of the experimental Mash into other Yahoo services, according to the company. Yahoo also hinted about adding social-networking functions to its e-mail service.
<p>
A Yahoo community manager said earlier this year that users' dedication to mashing had helped the community... http://www.sci-tech-today.com/story.xhtml?story_id=61614 http://www.sci-tech-today.com/story.xhtml?story_id=61614 Fri, 29 Aug 2008 13:30:48 -0500 Apple Won't Fix iPhone Passcode Hole Until September The latest iPhone embarrassment is a security hole that makes it simple to access stored data on supposedly locked iPhones. Apple said Thursday that a software patch to solve the problem is in the works.
<p>
An unauthorized user can exploit the security hole simply by double-pressing the button to make an emergency call. That behavior brings up the owner's preferred contacts and clicking on a number provides full access to the phone's features. Clicking on an e-mail provides access to all e-mail. And clicking on a contact name provides full access to all contacts data.
<p>
Apple spokesperson Jennifer Bowcock said, "The minor iPhone security issue which surfaced this week is fixed in a software update which will be released in September."
<p>
There is a simple workaround, Bowcock said: iPhone owners can simply change the settings so double-clicking the emergency button returns a user to the home screen, which will present a password login field if password protection is turned on.
<p>
<subhead>'Design Deficiency'</subhead>
<p>
While an attacker must be in physical possession of the iPhone to exploit the security bug, it "highlights a fundamental design deficiency with the iPhone," said Andrew Storms, director of security operations with nCircle Network Security.
<p>
"Despite Steve Jobs from day one saying the iPhone was secure, functionality and aesthetics of the device seem to always win out over security," Storms said. A case in point, Storms said, "Apple quickly released updates to fix 3G connectivity issues this year, but consistently takes many months to release security updates."
<p>
This particular security hole -- a simple bypass of access restrictions -- was created by Apple's preference for functionality over security, he added. "Even when a user chooses to physically secure the device with a four-digit passcode, Apple has chosen to still permit the user to use some functionality," Storms said. "By selecting to perform... http://www.sci-tech-today.com/story.xhtml?story_id=61613 http://www.sci-tech-today.com/story.xhtml?story_id=61613 Fri, 29 Aug 2008 13:31:07 -0500 Veoh Decision May Not Let Google Off the Hook In a first-of-its kind decision, a California federal court has dismissed a copyright-infringement lawsuit against online video-sharing site Veoh Networks. IO Group, an adult entertainment company, filed the suit against Veoh, alleging the site displayed its content in violation of copyright laws. But Magistrate Judge Howard Lloyd of the U.S. District Court in San Jose ruled against the gay-porn distributor on Wednesday.
<p>
IO Group's suit is not unlike Viacom's $1.6 billion lawsuit against Google-owned YouTube. In fact, MySpace, MP3tunes, Hi5, Stage6 and several other sites are facing similar battles over user-generated content.
<p>
Could this ruling be a boon for these sites? Or is the ruling merely an isolated incident in a California trial court? Google and the Electronic Frontier Foundation are betting on the former.
<p>
<subhead>
Web 2.0 Required Reading
</subhead>
<p>
EFF Legal Analyst Fred von Lohman said the ruling should be required reading for the executives of every Web 2.0 business that relies on user-generated content. The key to Veoh's victory, he said, was its scrupulous attention to the Digital Millennium Copyright Act's safe harbors.
<p>
"Veoh responded to compliant DMCA takedown notices on a same-day basis, it notified users of its policies against copyright infringement, it registered a copyright agent with the copyright office, it terminated users who were repeat infringers and blocked new registrations from the same e-mail addresses, it used hashes to stop the same infringing videos from being uploaded by other users," von Lohman wrote in the EFF blog.
<p>
As von Lohman sees it, Judge Lloyd's ruling debunks some of the favorite arguments of entertainment-industry lawyers and gives YouTube a boost in its billion-dollar battle against Viacom.
<p>
<subhead>
YouTube's Repeat Infringer Dilemma
</subhead>
<p>
But the Google case is a little different. While the California court did spell out that there is no affirmative obligation for service providers to track users or police their sites, the context of... http://www.sci-tech-today.com/story.xhtml?story_id=61612 http://www.sci-tech-today.com/story.xhtml?story_id=61612 Fri, 29 Aug 2008 09:30:56 -0500 Comcast Limits Homes To 250GB in New Public Policy Comcast has made it official: Home Internet service customers are limited to 250GB of data per month. According to the company, the move is in response to heavy usage by some customers that can cause network congestion.
<p>
The new policy was posted on Comcast's Web site early Friday, and the meter starts running on Oct. 1.
<p>
Charlie Douglas, director of corporate communications for online services, said, "The amount of data measured is aggregate monthly usage of uploads and downloads."
<p>
And Comcast has added some teeth to the usage limit -- the first time the limit is exceeded, the offending customer will receive a phone call from a Comcast representative. The second violation will result in a shutdown of Internet service for one year.
<p>
The amended service policy states in part: "It's no secret we've been evaluating a specific monthly data usage or bandwidth threshold for our Comcast High-Speed Internet residential customers for some time." The threshold is high for the majority of Comcast users.
<p>
Examples of what a 250GB limit equates to are cited in the amendment, such as sending 50 million e-mails, downloading 62,500 songs, 125 standard-definition movies, or uploading 25,000 high-resolution digital photos. The policy says the median monthly usage for residential Comcast customers is 2GB to 3GB per month.
<p>
<subhead>Bandwidth Hogs</subhead>
<p>
Some observers say Comcast has a reasonable argument. The company has expanded rapidly into business and residential phone service, meanwhile maintaining its large cable-television enterprise. There is only so much available bandwidth at any given time.
<p>
Comcast is moving data, voice and television and high-definition video over the same pipes. It only takes a few peer-to-peer file-sharing applications to cause unexpected congestion.
<p>
<subhead> Making Policies Public </subhead>
<p>
Comcast's previous efforts to address the problem brought a rebuke from the Federal Communications Commission. Comcast was caught throttling down the connections of BitTorrent P2P users on... http://www.sci-tech-today.com/story.xhtml?story_id=61611 http://www.sci-tech-today.com/story.xhtml?story_id=61611 Fri, 29 Aug 2008 10:09:06 -0500 Hackers Take Aim at Users of Facebook On the Internet, popularity often draws the attention of hackers. So it is not surprising that Facebook has become the target of a spate of attacks, just as the membership on the site has swelled to about 100 million active users worldwide.
<p>
In recent days, many Facebook users have seen a sharp increase in spam, some of it pretty racy. Over the weekend, several Facebook users contacted this newspaper saying that their accounts appeared to have been hijacked, and some said their accounts had been deactivated.
<p>
Facebook acknowledges that it has been under attack but suggested the problems were largely under control. "Over the past few days, we have received reports from users of spam and phishing attacks," the company said in a statement. "We have also detected and contained a worm. We are investigating every report, removing false content, blocking bogus links and addressing the concerns of our users. These efforts have limited the affected users to a small percentage of those on Facebook."
<p>
Some of the attacks were linked to Koobface, an Internet worm that began targeting Facebook and MySpace users in late July. Since then, the Internet security firm Kaspersky Lab has identified about 27 variants of Koobface.
<p>
"It is very similar to a lot of the old worms," said David Emm, a senior technology consultant at Kaspersky.
<p>
Emm said Koobface, like many other viruses and worms, relies on what is known as "social engineering" techniques, which attempt to trick people into performing actions that will expose them unwittingly to a virus.
<p>
The technique may prove particularly effective on social networks, he said.
<p>
"If you receive messages from a friend on a social network, you are not expecting them to be a vehicle to carry a worm or Trojan horse," Emm said.
<p>
In the wake of Koobface, that may change.
<p>
In the meantime, Facebook recommends... http://www.sci-tech-today.com/story.xhtml?story_id=61592 http://www.sci-tech-today.com/story.xhtml?story_id=61592 Fri, 29 Aug 2008 07:49:54 -0500 Blogger Arrested over Leak of Guns N' Roses Songs A blogger suspected of streaming songs from the unreleased Guns N' Roses album "Chinese Democracy" on his Web site was arrested Wednesday and appeared in court, where his bail was set at $10,000.
<p>
FBI agents arrested 27-year-old Kevin Cogill on Wednesday morning on suspicion of violating federal copyright laws. Cogill appeared in court in the afternoon wearing a T-shirt; his girlfriend sat court and afterward said, "Rally the troops," but declined further comment.
<p>
Federal authorities say Cogill posted nine unreleased Guns N' Roses songs on his Web site in June. The songs were later removed.
<p>
In later posts, Cogill wrote that the FBI had questioned him and asked his readers if any of them knew a good attorney. He was represented Wednesday by a federal public defender.
<p>
According to an arrest affidavit, Cogill admitted to agents that he posted the songs on his Web site. Prosecutors said Wednesday the leak could result in a "significant" financial loss for the band.
<p>
Cogill will not face any special Internet restrictions, but was ordered to appear in court for a preliminary hearing on Sept. 17.
<p>
"Guns N' Roses representatives have been made aware of the arrest and are leaving the matter to the authorities," said Larry Solters, the band's spokesman.
<p>
"Chinese Democracy" is a much anticipated -- and repeatedly delayed -- new album by Guns N' Roses that is more than 10 years in the making. At least one of the album's songs could be heard legally: The band wrote on its Web site in July that its track, "Shackler's Revenge" will be featured on the video game Rock Band 2, slated for release in September. http://www.sci-tech-today.com/story.xhtml?story_id=61590 http://www.sci-tech-today.com/story.xhtml?story_id=61590 Fri, 29 Aug 2008 07:57:15 -0500 Reborn Retail Site Fires Salvo in Shipping War With gas prices high and consumers stretching shopping dollars, competition is heating up online for deals -- and a discount retail site hopes to fan the flames by shipping orders for $1.95.
<p>
Chicago-based Enable Holdings Inc. plans to launch RedTag.com on Friday and sell retailers' excess inventory at a fixed price. Its shipping charge will undercut a similar site, Overstock.com Inc., which charges $2.95 for standard ground shipping.
<p>
"We're willing to take less for shipping because we think you'll buy five more items from us -- as opposed to if we got as much as we could from you, shipping this product, you may never buy again," said Enable Holdings' CEO, Jeffrey D. Hoffman.
<p>
The site is coming online a few months after gas hit $4 per gallon, a milestone that caused many consumers to see buying online as a way to make fewer car trips, said Scott Silverman, executive director of the National Retail Federation's digital division, Shop.org.
<p>
Even though fuel prices have come down, he thinks the habits consumers have adopted to save gas are still in place. Cheap or free shipping could be another way to keep them shopping on the Web.
<p>
This launch marks a revival of RedTag.com, which shuttered in 2004. Enable Holdings, which runs uBid.com, an auction site for excess inventory, bought the RedTag Internet address this spring from one of its major shareholders.
<p>
RedTag is selling items it gets mainly from retailers that have gone out of business, or manufacturers that have produced more of a product than was sold. Sometimes companies want to get an older model -- a laptop, for example -- off store shelves to make room for a new one.
<p>
By selling such excess goods, a site like RedTag has more flexibility than regular retailers in negotiating with manufacturers on the final price of a product,... http://www.sci-tech-today.com/story.xhtml?story_id=61586 http://www.sci-tech-today.com/story.xhtml?story_id=61586 Fri, 29 Aug 2008 08:00:26 -0500 Study: Missing Gene May Impair Appetite Control Some obese children and adults who eat excessively may be missing a gene for a brain chemical involved in controlling appetite, according to a study in today's New England Journal of Medicine.
<p>
Low levels of the chemical are also linked to long-term memory loss and difficulties in sensing pain.
<p>
Researchers at the National Institutes of Health examined 33 children and adults with a rare condition in which groups of genes have been deleted. Called WAGR syndrome, the genetic aberration is found in about 250 people in the USA.
<p>
Half of the people studied lacked one of two genes for a brain chemical called brain-derived neurotrophic factor (BDNF). The ones missing the gene had low blood levels of the chemical. By age 10, all of those missing the gene were obese and reported a strong tendency to overeat. Those who had two working copies of the BDNF gene were no more likely to be obese in childhood or to report unusually high levels of overeating than the general population.
<p>
Scientists suspected that people within the group had abnormalities with the gene, and they believe a larger segment of the population has the same problem.
<p>
The missing gene may explain why some people can't seem to control their eating or lose weight, says Jack Yanovski, head of the Unit on Growth and Obesity at NIH's Eunice Kennedy Shriver National Institute of Child Health and Human Development.
<p>
"We suspect that BDNF has important issues in many parts of the brain, including memory and ability to sense pain," he says.
<p>
Yanovski says the brain chemical works in combination with other chemicals in the body, including the hormone leptin, to regulate appetite and body weight. More research needs to be done so scientists can develop obesity drugs to treat people who don't make enough BDNF, he says.
<p>
"BDNF is just a small part... http://www.sci-tech-today.com/story.xhtml?story_id=61584 http://www.sci-tech-today.com/story.xhtml?story_id=61584 Fri, 29 Aug 2008 08:03:26 -0500 |
