Sad. The beaches down here, some of the most beautiful in the country, are ruined. Along with them goes the livelihood of hundreds of thousands of people who make their living off the tourist industry. BP may make billions a year, but there’s no way any amount of money, no matter what they do with it, will completely cover the loss resulting from this spill. Oiled beaches stay oiled beaches.

In quantum teleportation two photons or ions (for example) are entangled in such a way that when the quantum state of one is changed the state of the other also changes, as if the two were still connected. This enables quantum information to be teleported if one of the photons/ions is sent some distance away.
In previous experiments the photons were confined to fiber channels a few hundred meters long to ensure their state remained unchanged, but in the new experiments pairs of photons were entangled and then the higher-energy photon of the pair was sent through a free space channel 16 km long. The researchers, from the University of Science and Technology of China and Tsinghua University in Beijing, found that even at this distance the photon at the receiving end still responded to changes in state of the photon remaining behind. The average fidelity of the teleportation achieved was 89 percent.

The only reason Greece is not bankrupt now is because even as its past mistakes have caught up with it and climaxed in a solvency and liquidity crisis unseen since the Lehman days, the country’s end would bring down all of Europe. If Greece would not have impaired French, German and UK banks, the country would have long been allowed to default. Yet diversion is always a good tactic: let’s bring the “speculators” into this yet again. After all it is unheard of in these turbulent Keynesian times for anyone, especially our own Fed Chairman, to own up to their endless mistakes. It is always, without exception, someone else’s fault.

Microsoft released a beta today. From preliminary information, it looks like they’ve addressed most of my gripes with Windows Home Server 1.0. Interesting new features -
1) The ability to backup the entire WHS to a remote drive, at scheduled times. That’s nice for snapshotting the whole setup all at once.
2) Scheduled backups of Shared Folders. 1.0 supported quasi-raid style duplication of shared folders, but not regular backups - that was a feature limited to the PCs on your network. It’s nice they’ve integrated the content on the server into the nightly backups mechanism.
3) Shadow copy - real time backups of important areas of your file system on computers in your home. Very nice, I can think of a few areas (Documents, Mail, Desktop, my mozilla patches folder, etc.) that I’d like to have this for. Nightly backups are great, real-time backups for certain areas of your file system are kick ass. This should also (hopfully) integrate in with the existing Shadow Copy features built into Vista and Win7.
4) Simplified setup and configuration for the average Joe, with fine grained control for those that need it.
One bummer, Windows Media Center is not built-in in this rev.. That’s unfortunate, but not a deal killer. Your media can still sit on the the main WHS, and a secondary PC running Windows 7 can serve up the interface and content to the living room. This really isn’t a big deal since kicking into WMC from a 360 will automatically wake the PC serving up Media Center.
All-in-all, looks very promising. Generally speaking, if I knew setting up nightly backups and Shared Folders was as easy as it is with WHS, I would have done this two years ago. It’s really quite impressive, the system is “plug and play” for average users - buy a headless system, plug it in, and your up and running and your data is secure in minutes. Yet for power users like myself who just can’t help but want to get into things and tweak the crap out of them, the options are endless. Very cool.

Something obscure worth feeding to the internets – converting a pc system from headed (with a video card/display) to headless by removing the display AND video card to save on power can have some strange effects on your system. For one thing this will enable the default vgasys video driver within windows. On older systems (Windows Server 2003 and potentially XP) this vga driver is not ACPI (Advanced Configuration and Power Interface) compliant. When windows loads this driver, it can prevent you from placing the computer into sleep mode.
For Windows Home Server users - if you’re running Lights Out and you suddenly find the ’suspend state’ missing from the post-backup options, and you’ve been messing with video drivers, check to make sure the currently loaded driver supports ACPI. You can do this by opening a cmd window via Remote Desktop and typing ‘powercfg /availablesleepstates’.
I’ve been messing with WHS on my old dell XPS 210 after a recent upgrade to a newer four core Dell system (sweetness) for development work. I should have a review out here in a bit. I really wanted to give WHS a spin before plunking down $ on a pre-built system. All-in-all, the backups and file/media sharing worked great out of the box. (I do have some gripes though, power management is one of them.) I’ll post about the experience down the road. My personal suggestion would be not to build one on your own, buy one of the headless preconfigured systems out there. (Windows Server 2003 driver issues with my dell system were my biggest frustration.) Better yet, wait a year until the new Win7 based ‘Vail’ systems come out, which is what I’m planning on doing.

“In short, GM is using government money to pay back government money to get more government money. And at a 2% lower interest rate at that.”

“This is mind-boggling. There’s no possible technical justification for this. It’s pure evil.”

I just touched up a number of encoding issues post a Word Press upgrade. A number of old posts might show up as recent… sorry for the blog spam.

For a company whose CEO professes a hatred of DRM, Apple sure has made DRM its alpha and omega. Having gotten into business with the two industries that most believe that you shouldn’t be able to modify your hardware, load your own software on it, write software for it, override instructions given to it by the mothership (the entertainment industry and the phone companies), Apple has defined its business around these principles. It uses DRM to control what can run on your devices, which means that Apple’s customers can’t take their “iContent” with them to competing devices, and Apple developers can’t sell on their own terms.
For years I’ve listened to Apple fans proclaim monopolies as being “bad”, yet today they seem perfectly comfortable in accepting the same model now that it’s enforced through the content and devices of their favorite company. complaint > dev/null.

As for the Treasury Department, they’ll be selling a whopping $165 billion in debt this week including some $82 billion in long-dated issues - $40 billion 3-year notes, $21 billion in 10-year notes, $13 billion in 30-year bonds, and $8 billion in 10-year TIPS. This has become almost a routine, every-other-week affair that could see its first big headwind in the days ahead if yields keep rising.
