SSD Won't Make Sense In Laptops For Two Years
kgagne writes "While solid state disk drives can vastly improve random read performance and are perfectly suited to most mobile devices, many operations are sequential in laptops and desktops and involve writes where SSDs most often lose to magnetic hard disk drives in performance. While introducing multi-channel flash memory controllers and interleaving the NAND flash chips increases performance, it will still be about two years before the cost versus benefit ratio will make sense to install SSD in your laptop or desktop PC, according to a Computerworld story. 'I think you need to get to 128GB for around $200, and that's going to happen around 2010. Also, the industry needs to effectively communicate why consumers or enterprise users should pay more for less storage," says Joseph Unsworth, an analyst at Gartner Inc.'"

Comcast To Cap Data Transfers At 250 GB In October
JagsLive writes with this story from PC Magazine: "Comcast has confirmed that all residential customers will be subject to a 250 gigabyte per month data limit starting October 1. 'This is the same system we have in place today,' Comcast wrote in an amendment to its acceptable use policy. 'The only difference is that we will now provide a limit by which a customer may be contacted.' The cable provider insisted that 250 GB is "an extremely large amount of data, much more than a typical residential customer uses on a monthly basis. ... As part of our pre-existing policy, we will continue to contact the top users of our high-speed Internet service and ask them to curb their usage,' Comcast said Thursday. 'If a customer uses more than 250 GB and is one of the top users of our service, he or she may be contacted by Comcast to notify them of excessive use,' according to the AUP."

Hashing Email Addresses For Web Considered Harmful
cce writes "The MicroID standard, despite getting thrashed soundly by Ben Laurie two years ago, has since been recommended by the DataPortability Project and published on the user profiles of millions of users at Digg and Last.fm. MicroID is basically a hash calculated using a user's profile page URL and registered email address, producing a token that makes the email address vulnerable to dictionary attacks. To see how easy it was to crack these tokens, I conducted a small study, choosing 56,775 random Digg users, and cracking the email addresses of 14,294 of them (25%) using just their MicroID, username, and a list of popular email domains. Digg has more than 2 million users, and that means half a million of them — mostly people who had never heard of MicroID, and had probably not logged in for a long time — had their email addresses exposed to this trivial attack. I also applied this attack to Last.fm (19%) and ClaimID (34%). Digg and Last.fm have since removed support for MicroID, but the lesson is clear: don't publish a hash of my email address online, guys!"

Black Screens For Unauthorized Copies of Windows
arcticstoat writes "In a bid to deter people from using pirate versions of Windows XP, Microsoft is now updating its Windows Genuine Advantage (WGA) tool to introduce a few uncomfortable niggles for users of pirated versions of Windows. These include replacing the desktop wallpaper with a black screen every 60 minutes, although you can still replace it with your wallpaper of choice in the intervening period. As well as this, copies of Windows deemed to not be genuine will also have a translucent watermark above the system tray, which Microsoft calls a 'persistent desktop notification.'"

Cost-Effective Server Room Air Conditioning?
at0mic26 writes "I am currently tasked with finding a cost effective solution to our 30+ degree Celsius server room. The only air conditioning currently provided is a single duct pipe from one of two air conditioner units. I was thinking of stealing air from the second air conditioning unit with some sheet metal work, but it likely will not be sufficient — and would not have tolerance for both AC units being offline for any amount of time. An ideal supplemental portable AC unit is what I am after, however I'm finding it cost prohibitive, with $600+ humidity controlled AC unit, plus 20 amp socket requirement, plus contract work to make a hole in the wall for outside drainage so that the unit does not flood the place. What sort of successful cheaper air conditioning solutions have you come up with?"

Bell Labs Kills Fundamental Physics Research
An anonymous reader writes with this snippet from Wired: "After six Nobel Prizes, the invention of the transistor, laser and countless contributions to computer science and technology, it is the end of the road for Bell Labs' fundamental physics research lab. Alcatel-Lucent, the parent company of Bell Labs, is pulling out of basic science, material physics and semiconductor research and will instead be focusing on more immediately marketable areas such as networking, high-speed electronics, wireless, nanotechnology and software." Jamie points out this list of Bell Labs' accomplishments at Wikipedia, including little things like the UNIX operating system.

Will W3C Accept DRM For Webfonts?
dotne writes "Microsoft has submitted Embedded OpenType (EOT) to W3C and a slimy campaign for EOT has been launched. EOT is a DRM layer on top of normal TrueType/Opentype files; EOT ties a font file to a certain web page or site and prevents reuse by other pages/sites. Microsoft's IE has supported EOT for years, but it has largely been ignored due to the clumsiness of having to regenerate font files when a page changes. Now that other browsers are moving to support normal TrueType and OpenType on the web (Safari, Opera, Mozilla, Prince), W3C is faced with a question: should they bless Microsoft's EOT for use on the web? Or, should they encourage normal font files on the web and help break Microsoft's forgotten monopoly?"

Lenovo Requires NDA For Windows License Refund
tykev writes "A customer wanted to return the license for preinstalled Windows Vista Business that came with his Lenovo laptop. After some lengthy negotiations with representatives of Lenovo's technical support and management, he was offered financial compensation for returning the license in the amount of CZK 1950 (USD 130, EUR 78), pending his acceptance of a non-disclosure agreement that would cover the entire negotiations with the company and its results. He declined and published his experiences on a Czech Linux website. The website editors decided to reward the customer for publishing the article by paying him an author's royalty in the same amount as was the offered compensation for returning the license."

Case Against Video-Sharing Site Dismissed
NewYorkCountryLawyer writes "A California copyright infringement case brought by an adult video maker against a video sharing web site, Veoh Networks, has been thrown out, based upon the 'safe harbor' provision of the Digital Millennium Copyright Act ('DMCA'). In a 33-page decision (PDF), the Court concluded that Veoh was covered by the DMCA, and had carried out its duties to comply with takedown notices in a reasonable manner. The Court rejected the plaintiff's arguments showing possible ways that users could do an end-around, saying that the law requires 'reasonable' compliance, rather than perfection, and noted that the DMCA is 'designed to facilitate the robust development and world-wide expansion of electronic commerce, communications, research, development, and education in the digital age'."

Slashdot's Disagree Mail
There is an old Japanese proverb that goes, "Better than a thousand days of diligent study is one day with a great teacher." This week's mail is all about teaching. Whether it is about the seriousness of psychic ability, a short history of trolls or explaining how much free time and malice your dad's attorney has, these people just want to impart information. If what they sent me is any indication, they had a lot of sick days. Click on the link below to become enlightened.
