Submission + - Bluetooth & Wi-Fi co-existence

Submitted by
Shakrai
Shakrai writes: "A question for those with more experience with Bluetooth then I have: Has anybody noted/worked-around/been-able to solve co-existence problems with bluetooth and 802.11b/g WLANs? I'm playing around with the T-Mobile T-Mobile HotSpot @ Home service at the office for our directors and while the service works great, the heavy network traffic on the wireless lan renders bluetooth headsets unusable. Short pops of static occur about ten times a second. The WLAN itself doesn't even seem to notice.

Given that Bluetooth's design purposefully uses the entire range of unlicensed channels on 2.4Ghz I'd given up on trying to get it to co-exist with WLANs. But I've noted that Bluetooth 1.2 includes support for "Adaptive frequency-hopping spread spectrum", which theoretically will remove crowded channels from the hopping sequence. Given that a single 802.11b/g access point only uses a portion (roughly 1/3) of the band available to Bluetooth, wouldn't it stand to reason that Bluetooth and Wi-Fi can be made to peacefully co-exist?

Perhaps the problem lies with the cheap headsets that my company is providing us? Does anybody have any experience with particular models of Bluetooth headsets used in a heavy wi-fi environment? Or any experience with the actual HotSpot service and the phones that T-Mobile offers? Does any model of phone or headset stand out as being better at co-existing then the others?"

Submission + - eBay Auctions Canceled for Charging Too Little

Submitted by jcgam69
jcgam69 writes: Although interference with eBay sales is nothing new, companies in two recently filed federal cases explicitly invoke Leegin as a justification for terminating the eBay auctions of competitors that charge lower prices online. These cases not only show Leegin's likely effect on Internet sales, but are also, unfortunately, fairly typical examples of the sort of anticompetitive actions companies take to fight lower-priced competition online.

Submission + - Do you support the GPLv3?

Submitted by Anonymous Coward
An anonymous reader writes: So the blogs and MSM have been at it since the official GPLv3 release. Is the GPLv3 a measured response to new legal threats? Is the GPLv3 an extension of the spirit of GPLv2? Will the provisions of the GPLv3 regarding the use of DRM affect your deployments? Do you agree with Linus in his opposition to GPLv3, or do you agree with RMS? Will you switch from Linux to Solaris if it becomes GPLv3? Do you think the FSF is GNU/Arrogant? Do you think Linus is GNU/Naive?

Submission + - Passive VGA coolers beat reference heatsink (madshrimps.be)

Submitted by jmke
jmke writes: If you bought a mid-range video card recently and you're stuck with reference stock cooling making noise, there is hope, for less than $30 you can upgrade the cooling to completely passive solution and have the video card running cooler than it did before; this article compares 8 different 3rd party video card heatsinks and comes to the conclusion that the cheapest and passively cooled unit is the best on to get.

Submission + - FBI Investigates Online 'Hitman' Scams

Submitted by
Billosaur
Billosaur writes: "CNN is reporting that the FBI is looking into a new breed of on-line scam: 'The Hitman Scam'. The FBI has received more than 100 complaints about the scam, which involves the target receiving an email stating that one of their "friends" has put out a contract on them, and for a sum (anywhere from $30K to $80K dollars), the "hitman" will instead leave them alone.

FBI special agent James Burrell says some people have fallen for the scam, sending criminals tens of thousands of dollars. The FBI says they have some leads in the case, but they wouldn't provide specific details.


Given that the emails can be sent from anywhere, especially overseas, tracking the scammer becomes more difficult. It is believed to be merely a scam, as the email rarely contains any personal or specific information that would lead them to believe it was real. However, that is not always the case — in at least one instance, a victim received a follow-up email that did contain personal data."

Submission + - Kilimanjaro's shrinking snow not Global Warming

Submitted by phantomfive
phantomfive writes: Although it's obvious that not all warm summers can be attributed to global warming, apparently not all shrinking glaciers can be either. Mt. Kilimanjaro's snowpack has been shrinking for at least 100 years, before global warming really picked up. The shrinking is due to a number of factors, including reduced snowfall. Pictures here.

Submitted by

eldavojohn writes: "The game "Resistance: Fall of Man" has been called sick & sacreligious by the Church of England due to a point in the game in which rival gunmen kill hundreds inside Manchester cathedral. The Church of England said that Sony did not ask for permission to use the cathedral in their game and demanded an apology. The bishop of Manchester is quoted as saying, "It is well known that Manchester has a gun crime problem. For a global manufacturer to recreate one of our great cathedrals with photorealistic quality and then encourage people to have gunbattles in the building is beyond belief and highly irresponsible." A representative for Sony said a formal letter of apology will be sent Monday."

RFC
RFC writes: "The House committees responsible for copyright and education wrote a joint letter May 1 scolding the presidents of 19 major American universities, demanding that each school respond to a six-page questionnaire detailing steps it has taken to curtail illegal music and movie file-sharing on campus. One of the questions — "Does your institution expel violating students?" — shows just how out-of-control the futile battle against campus downloading has become."

Submission + - Six Multi-Service IM Clients Reviewed (extremetech.com)

Submitted by
mikemuch
mikemuch writes: "It's been a while since AOL stopped trying to jam third-party IM clients like Cerulean Studios' Trillian. ExtremeTech has posted a roundup of free alternatives to the standard IM software from the big boys — AIM, Yahoo Messenger, and MSN (now Windows Live) Messenger. The products are a mixed bag, some of them Web 2.0-based, like the excellent meebo and the ad-heavy eBuddy. Most give you combined message windows with tabs. GAIM is now Pidgin, Meetro tries to get you chatting with locals, and Trillian, now at version 3.1, remains the client to beat."

Submission + - Encrypted & Private File-Sharing Thrives in Eu (gigatribe.com)

Submitted by
johnarama
johnarama writes: "We've seen lots written about file-sharing apps such as Kazaa and eMule, and even more about the sue-happy RIAA lawyers trying to make up for declining CD sales by collecting fines from unsuspecting downloaders. What we haven't read much about, however, is the new trend of encrypted file-sharing, which keeps all file-transfers out of the radar and lets downloaders exchange with each other without having to look over their shoulder! One such product, GigaTribe ( http://www.gigatribe.com/ ), quietly introduced in the US last December, and already adopted by over 400,000 registered users, lets users exchange files with each other within small, private communities of friends. The advantage of this sort of file sharing is that users know each other and are less likely to download infected or mislabeled files. The disadvantage of course, is the smaller selection of files to choose from. Such private and encrypted file sharing has grown quite common in Europe, and may be the next big thing in the US unless players like Kazaa and eMule can figure out a way to hide those generous users who are inviting the world to copy their music collections."

Submission + - Forensics Meets Its Match: New Tools Thwart Police (cio.com)

rabblerouzer writes: "Antiforensic tools have slid down the technical food chain, from Unix to Windows, from something only elite users could master to something nontechnical users can operate. "Five years ago, you could count on one hand the number of people who could do a lot of these things," says one investigator. "Now it's hobby level." Take, for example, TimeStomp. Forensic investigators poring over compromised systems where Timestomp was used often find files that were created 10 years from now, accessed two years ago and never modified."
