OS X 10.8 (Mountain Lion) Won't Support Some 64-bit Macs With Older GPUs 417

MojoKid writes "Apple is pitching Mac OS X 10.8 (Mountain Lion) as the cat's meow, with over 200 new features 'that add up to an amazing Mac experience' — but that only applies if you're rocking a compatible system. Some older Mac models, including ones that are 64-bit capable, aren't invited to the Mountain Lion party, and it's likely because of the GPU. It's being reported (unofficially) that an updated graphics architecture intended to smooth out performance in OS X's graphics subsystem is the underlying issue. It's no coincidence, then, that the unsupported GPUs happen to be ones that were fairly common back before 64-bit support became mainstream."

Dolby's TrueHD 96K Upsampling To Improve Sound On Blu-Rays 255

Stowie101 writes in with a story about your Blu-ray audio getting better. "The audio on most Blu-ray discs is sampled at 48kHz. Even the original movie tracks are usually only recorded at 48kHz, so once a movie migrates to disc, there isn't much that can be done. Dolby's new system upsamples that audio signal to 96kHz at the master stage prior to the Dolby TrueHD encoding, so you get lossless audio with fewer digital artifacts. The 'fewer digital artifacts' part comes from a feature of Dolby's upsampling process called de-apodizing, which corrects a prevalent digital artifact known as pre-ringing. Pre-ringing is often introduced in the capture and creation process and adds a digital harshness to the audio. The apodizing filter masks the effect of pre-ringing by placing it behind the source tone — the listener can't hear the pre-ringing because it's behind the more prevalent original signal."

Connecticut Resident Stopped By State Police For Radioactivity 545

Okian Warrior writes "A Milford, CT man was pulled over when a state police car radioactivity scanner flagged his car as being radioactive. The man had been given a cardiac exam using radioactive dye, and had a note from his physician attesting to this, but it raises questions about the legality of the stop. Given that it is not illegal to own or purchase or transport radioactive materials (within limits for hobbyist use), should the police be allowed to stop and search vehicles which show a slight level of radioactivity?"

Only logon information about accounts that have logged on onto that device are being cached. Not all accounts, that would too resource intensive. Also that information is not obtained from a domain controller, but from user input.

So you can only compromise accounts that are used on that computer. However if you could steal a domain controller than you are correct. But the same goes for authentication servers from any other vendor.

Almost a Million UK Homes Will Suffer 4G TV interference 166

First time accepted submitter Nick Fel writes "As the UK nears the end of a lengthy digital TV switch-over, the sale of the analogue TV spectrum for 4G mobile phones will disrupt digital TV in almost a million homes. Affected homes will be issued with a filter or required to upgrade to satellite or cable, and in extreme cases may be granted funding to find their own solution."

You are correct.

If you read the article closely, you will notice it is not about the productions systems, but the testing systems of the Quality Assurance Division.

It makes sense to use VM's for Q & A just for flexibility. If your production storage is about a few hunderd PB, 100 TB for testing seems obvious. When you run production on the scale of eBay, Doing Q & A work on just a server or 2 doesn't work out.

I suspect they need 4000 VM's for Q & A, for more than just simulating the production system. For instance they are likely to test on multiple EBay instances for multiple projects or versions of their own software. They might also need a lot of systems to test data replication. And of course they need to simulate a lot of simultaneous clients for performance and reliability test, you need systems for that too. When Q & A work is done on that scale you need to collect, store, and analyze huge amounts of testing data.

Of course when this works out fine, eventually the production storage will likely be equipped with SSD technology as well.
