Comcast Cheating On Bandwidth Testing? 287

Posted by kdawson from the tuning-for-the-benchmark dept.
dynamo52 writes "I'm a freelance network admin serving mainly small business clients. Over the last few months, I have noticed that any time I run any type of bandwidth testing for clients with Comcast accounts, the results have been amazingly fast — with some connections, Speakeasy will report up to 15 Mbps down and 4 Mbps up. Of course, clients get nowhere near this performance in everyday usage. (This can be quite annoying when trying to determine whether a client needs to switch over to a T1 or if their current ISP will suffice.) Upon further investigation, it appears that Comcast is delivering this bandwidth only for a few seconds after any new request and it is immediately throttled down. Doing a download and upload test using a significantly large file (100+ MB) yields results more in line with everyday usage experience, usually about 1.2 Mbps down and about 250 Kbps up (but it varies). Is there any valid reason why Comcast would front-load transfers in this way, or is it merely an effort to prevent end-users from being able to assess their bandwidth accurately? Does anybody know of other ISPs using similar practices?"

Apple QuickTime DRM Disables Video Editing Apps 448

Posted by kdawson from the what-is-this-uninstall-you-speak-of dept.
An anonymous reader writes "According to numerous posts on Apple's discussion forums (several threads of which have been deleted by Apple), as well as a number of popular video editing blogs, Apple's recent QT 7.4 update does more than just enable iTunes video rentals — it also disables Adobe's professional After Effects video editing software. Attempting to render video files after the update results in a DRM permissions error. Unfortunately, it is not possible to roll back to a previous version of QT without doing a full OSX reinstall. Previous QT updates have also been known to have severe issues with pro video editing apps."

Comcast Promising Ultra-Fast Internet 314

Posted by kdawson from the whole-lotta-hd-video dept.
Espectr0 writes "Comcast's CEO Brian Roberts gave The Associated Press a preview of his speech for the Consumer Electronics show, and said that Comcast expects to demonstrate a technology that delivers up to 160 megabits of data per second over cable. At that speed you could download a high-definition copy of 'Batman Begins' in four minutes. The technology, DOCSIS 3.0, will start rolling out this year." Here's a note about Cisco's announcement of their DOCSIS 3.0 cable modem.

Study Warns of Internet Brownouts By 2010 318

Posted by kdawson from the told-you-them-pipes-was-too-small dept.
Bergkamp10 writes "Consumer and corporate use of the Internet could overload the current capacity and lead to brown-outs in two years unless backbone providers invest billions of dollars in new infrastructure, according to a new study. A flood of new video and other Web content could overwhelm the Net by 2010 unless backbone providers invest up to US $137 billion in new capacity, more than double what service providers plan to invest, according to the study by Nemertes Research Group. In North America alone, backbone investments of $42 billion to $55 billion will be needed in the next three to five years to keep up with demand, Nemertes said. Quoting from the study: 'Our findings indicate that although core fiber and switching/routing resources will scale nicely to support virtually any conceivable user demand, Internet access infrastructure, specifically in North America, will likely cease to be adequate for supporting demand within the next three to five years.' Internet users will create 161 exabytes of new data this year."
It's funny. Laugh.

Facebook Goes To 64 Bit User IDs 144

Posted by Zonk from the internet-users-on-mars-or-europa-can-expect-to-sign-up-soon dept.
NewsCloud writes "Facebook has announced to developers that they are moving to a 64 bit user ID in November. At 32 bits, the current ID allows nearly 4.3 billion user accounts. Yet, despite having only 47 million users today, Facebook's move to 64 bits will allow it to have more than 18 quintillion (18,446,744,074,000,000,000) user accounts. Of course, there are currently only about 6.5 billion people in the world. Is Facebook setting their sights beyond Earth or just trying to avoid what happened when Slashdot ran out of space for comment IDs last year. Perhaps they are planning to implement personas."

Apple Cuts Off Linux iPod Users 854

Posted by Zonk from the can't-stand-the-heat dept.
Will Fisher writes "New iPods will no longer be able to work with Linux. iTunes now writes some kind of hash (SHA1, md5?) to the iPod database which new iPods check against. If this check fails then the iPod reports that it contains 0 songs. This appears to be protection against 3rd party applications writing out their own databases. We haven't found out how to generate our own valid hashes (but we do know the hash includes the database itself, and possibly the iPod serial number), and are looking for help."

US Government Checking Up On Vista Users? 291

Posted by Zonk from the security-theatre-in-your-home dept.
Paris The Pirate writes "This article at Whitedust displays some very interesting logs from Vista showing connections to the DoD Information Networking Center, United Nations Development program and the Halliburton Company; for no reason other than the machine was running Vista. From the article 'After running Vista for only a few days — with a complete love for the new platform the first sign of trouble erupted. I began noticing latency on my home network connection — so I booted my port sniffing software and networking tools to see what was happening. What I found was foundation shaking. The two images below show graphical depictions of what has and IS trying to connect to my computer even in an idle state'."

Documents Reveal US Incompetence with Word, Iraq 419

Posted by Zonk from the see-there's-this-thing-called-covering-your-tracks dept.
notNeilCasey writes "The U.S. Coalition Provisional Authority, which formerly governed Iraq, accidentally published Microsoft Word documents containing information never meant for the public, according to an article in Salon. By viewing the documents using the Track Changes feature in Word (.doc), the author has been able to reconstruct internal discussions from 2004 which reflect the optimism, isolation and incompetence of the American occupation. Download the author's source document or look for more yourself. 'Presumably, staffers at the CPA's Information Management Unit, which produced the weekly reports, were cutting and pasting large sections of text into the reports and then eliminating all but the few short passages they needed. Much of the material they were cribbing seems to have come from the kind of sensitive, security-related documents that were never meant to be available to the public. In fact, about half of the 20 improperly redacted documents I downloaded, including the March 28 report, contain deleted portions that all seem to come from one single, 1,000-word security memo. The editors kept pulling text from a document titled "Why Are the Attacks Down in Al-Anbar Province -- Several Theories." (The security memo and the last page of the March 28 report can be seen here, along with several other CPA documents that can be downloaded.)'"

Submission + - Comcast and logic don't mix: disconnected

Submitted by marcmerlin
marcmerlin writes: If comcast decides that you are using too much data on your cable modem, they will disconnect you. Of course, they do not say what too much is, that's for you to guess.
Now, they do actually attempt to give you a chance to fix your overusage by warning you once, except in my case, they warned me half way through the month, and then shut me down for the good the next month due to the traffic that had gone out before they warned me. They warned me in a way that they were unable to measure the drastic traffic decrease after I fixed the problem, and they had to shut me down anyway. Their support people actually acknowledged that in my case there was indeed nothing I could have done, but they also said there was nothing they could do either due to the way their system works.
Until they fix their warning system to match logging cycles, or honor the one month grace period they promised me, and then pretended they never had, I can see how they're going to get many other people shut down that way.
If comcast is actually meaning to give their customers a chance to fix a usage over an arbitrary limit they won't disclose, they have some serious fixing to do, starting by not putting their customers in the criminal/DMCA pile that their regular support folks are not even allowed to help.

4 GB May Be Vista's RAM Sweet Spot 767

Posted by kdawson from the honkin' dept.
jcatcw writes "David Short, an IBM consultant who works in the Global Services Division and has been beta testing Vista for two years, says users should consider 4GB of RAM if they really want optimum Vista performance. With Vista's minimum requirement of 512MB of RAM, Vista will deliver performance that's 'sub-XP,' he says. (Dell and others recommend 2GB.) One reason: SuperFetch, which fetches applications and data, and feeds them into RAM to make them accessible more quickly. More RAM means more caching."

Verisign Retains .com Control Until 2012 92

Posted by kdawson from the same-as-the-old-boss dept.
Several readers wrote to note that the U.S. Department of Commerce, in a controversial deal, has extended Verisign's control of the .com domain. Verisign got the right to raise prices in four of the six years of the contract, by up to 7% each time. From the article: "Verisign has control of .com and .net locked up for the next several years, but there will still be a modicum of oversight. [Commerce] retains final approval over any price hikes, and has said that any subsequent renewal of the contract will occur 'only if it concludes that the approval will serve the public interest in the continued security and stability of the Internet domain name system... and the provision of registry services at reasonable prices, terms and conditions.'"

EU Prepared to Fine Microsoft $2.5 Million Per Day 659

Posted by Zonk from the i'd-get-on-that-guys dept.
Lord_Slepnir writes "The European Union is unsatisfied with Microsoft's compliance with their anti-trust compliance from 2004, and is preparing to fine them 2 million Euros ($2.5m US) per day until they comply. Under that ruling, Microsoft must open up parts of their operating system to competitors, and change how they bundle Media Player." From the article: "On Monday, Microsoft said it had begun to provide the information Brussels had demanded, but the Commission has signaled the company acted too late. In December, Brussels informed the software giant that it had failed to comply with the original ruling it issued in March 2004."
