An anonymous reader notes an Inquirer story reporting on something of a breakthrough in virtual machine management — a demonstration (not yet a product) of migrating a running virtual machine across CPUs from different vendors (video here). "Red Hat and AMD have just done the so called impossible, and demonstrated VM live migration across CPU architectures. Not only that, they have demonstrated it across CPU vendors, potentially commoditizing server processors. This is quite a feat. Only a few months ago during VMworld, Intel and VMware claimed that this was impossible. Judging by an initial response, VMware is quite irked by this KVM accomplishment and they are pointing to stability concerns. This sound like scaremongering to me ... All the interesting controversy aside, cross-vendor migration is [obviously] a good thing for customers because it avoids platform lock-in."

Khemisty writes "Back in grade school you were probably taught the importance of warm-up exercises, and it's likely you've continued with pretty much the same routine ever since. Science, however, has moved on. Researchers now believe that some of the more entrenched elements of many athletes' warm-up regimens are not only a waste of time but are actually bad for you. The old presumption that holding a stretch for 20 to 30 seconds — known as static stretching — primes muscles for a workout is dead wrong. It actually weakens them. In a recent study conducted at the University of Nevada, athletes generated less force from their leg muscles after static stretching than they did after not stretching at all. Other studies have found that this stretching decreases muscle strength by as much as 30 percent. Also, stretching one leg's muscles can reduce strength in the other leg as well, probably because the central nervous system rebels against the movements."

Glenn Fleishman writes "The reports earlier today on WPA's TKIP key type being cracked were incorrect. I spoke at length with Erik Tews, the joint author of the paper that discloses a checksum weakness in TKIP that allows individual short packets to be decrypted without revealing the TKIP key. I wrote this up for Ars Technica with quite a bit of background on WEP and WPA. Tews's paper, co-written with Martin Beck, whom he credits as discovering and implementing a working crack (in aircrack-ng as a module), describes a way to use a backwards-compatible part of TKIP to exploit a weakness that remains from WEP. ARP packets and similarly short packets can be decoded. Longer packets are likely still safe, and TKIP hasn't been cracked. Don't believe the hype, but the exploit is still notable."

Smelly Jeffrey writes "With the release of this whitepaper, the FCC unanimously approved plans for a new technology with strong supporters and even stronger detractors. White Space Wi-Fi effectively allows manufacturers of wireless devices to incorporate transceivers that operate on unused DTV channels. Although the deregulation is new, the idea seems to have caught Google's interest recently as well. It seems that this has been rather rushed through the normally stagnant channels at the FCC. While some view it as interference in the already crowded spectrum, it seems the FCC Chairman really likes the idea of re-purposing dark parts of the newly allocated DTV bands once more." Update: 11/06 18:15 GMT by T : You may want to look at Tuesday's mention of the decision as well, but the additional links here are interesting.

An anonymous reader writes "As a sequel to their Is Ubuntu Getting Slower? Phoronix now has out an article that compares the performance of Ubuntu 8.10 to Apple's Mac OS X 10.5.5. They tested both the x86 and x86_64 spins of Ubuntu and threw at both operating systems a number of graphics, disk, computational, and Java benchmarks, among others. With the Mac Mini used in some of the comparisons, 'Leopard' was faster, while in others it was a tight battle."

Joystiq's Law of the Game column uses the recently released LittleBigPlanet to address the question of intellectual property rights for user-created content within and for games. At this point, Sony's ToS claims a great deal of control over users' work, unlike Second Life's, which is much more permissive. GiantBomb has a related story pointing out creations within LittleBigPlanet that are copies of other games, and how they could lead to legal troubles for Sony if they aren't quick about taking them down.

MojoKid writes "Today marks the official launch of Intel's new Core i7 processor, the most major overhaul of Intel's core processor architecture since the release of their Core 2 design. As has been reported, the Core i7 is a major departure from Intel's aging Front Side Bus architecture of old, now replaced by Intel's QPI (Quick Path Interconnect) serial links. This 20 lane bi-directional (40 lanes total) point-to-point connection provides 6.4 GT/s of bandwidth and scalability for future multi-socket designs as well. In addition, the Core i7 now has an integrated triple channel memory controller offering over 3X the bandwidth of the previous Core 2 architecture with DDR3 system memory. Though the product is set to ship in volume later this month, the early benchmark numbers show Intel's new chip is markedly faster clock-for-clock versus their previous generation CPU and much faster than anything AMD has out currently."

CNet is reporting that Netflix has opened up its "Watch Instantly" feature to Mac users (here is Netflix's blog entry). They accomplished this by using Microsoft's Silverlight technology on both platforms, abandoning the Windows Media Player solution that had been employed in the first, Windows-only, version. Silverlight's DRM capabilities meet Netflix's needs, apparently. Netflix warns that this is beta software. Mac users can opt in here, then watch instantly with Safari or Firefox 2+, with the Silverlight plugin in place. Movie selection is somewhat limited.

danaris writes in to inform us that John Gruber has done some digging on the reported rejection from the App Store of Opera Mini, and has written up his findings. Some choice excerpts: "My understanding, based on information from informed sources who do not wish to be identified because they were not authorized by their employers, is that Opera has developed an iPhone version of Opera Mini — but they haven't even submitted it to Apple, let alone had it be rejected. ... If what they've done for the iPhone is [to get] a Java ME runtime running on the iPhone — it's clearly outside the bounds of the iPhone SDK Agreement. ... What Opera would need to do to have a version of Opera Mini they could submit to the App Store would be to port the entire client software to the C and Objective-C APIs officially supported on the iPhone. It could well be that even then, Apple would reject it from the App Store on anti-competitive grounds — but contrary to this week's speculation, that has not happened."

Eurogamer has an in-depth look at the new Xbox Experience, which is coming on November 19th. They discuss the new interface and features, and their reaction is generally positive, citing graphical improvements, smooth file management, and better chat functionality. "The Guide is also your access point to the new Party system, where you can gather eight of your friends together in a voice-chat channel and move the group between games. You don't even have to be doing the same thing: you can just chat along regardless. And because it's a service layer, it automatically works with all your existing games. Gears of War treats it like it's always been there. Instead of inviting a player, you invite the group; instead of ending a session and having to reassemble for another, you stay together. You can open it up to friends or set it to be invite-only, and while it's one of NXE's quieter additions, it's also its most authoritative statement: this is Microsoft saying, 'We figured we might need to do something like this, so we made sure we could.'"

arcticstoat writes "If you thought that EA might have been humbled by the massive Internet backlash against its use of SecuROM in its recent games, then you'd be wrong. Speaking at the Dow Jones/Nielsen Media and Money Conference, EA's CEO John Riccitiello claimed that the whole issue had been blown out of all proportion. 'We implemented a form of DRM and it's something that 99.8 per cent of users wouldn't notice,' claimed Riccitiello, 'but for the other 0.2 percent, it became an issue and a number of them launched a cabal online to protest against it.'"

farkinga writes "For those of us that no longer have a television, live TV events can be a challenge to watch. Fortunately, tonight's Presidential Debate has attracted the attention of most US broadcasters, many of whom will provide online viewing options. Leading the way is Hulu, a joint venture between NBC Universal and News Corp, who will stream the Fox-branded feed tonight — assuming they worked out the bandwidth issues that came up during the second debate!"
