Submission + - A magnetic fridge? Maybe someday (

batteryman writes: If you use a strong magnetic field to control the entropy of a special kind of material, you could make yourself a magnetic fridge. The stronger the magnetic field, the lower the entropy and the heat capacity of the material. When the magnetic field is subsequently switched off, the heat capacity of the material rises. Researchers from the Lawrence Berkeley National Lab say a magnetic fridge using such material would consume less electricity than today’s fridges, which account for 8% of a family’s utility bill.

Because it works for me. I put my original Windows hard drive back into my laptop and it was painfully slow. I do have problems with my MP3 player and HD camera. In Windows it shows up as two drives. I'll get it working some day. My laptop PCMCIA Audigy ZS card works. I plugged in my old video camera with Firewire, Sony 350 and it not only saw it, it told me what model of camera it was. It depends on which distribution you use.

Linux supports USB 3.0 thanks to Intel. Does Windows?

Comment Rescan Your TV or Converter Box (Score 2, Informative) 434

Some stations have the option to go back to their old channel as a digital station. That means that these stations will be giving up their second channel that they have been using as their digital channel. Here in the Los Angeles area the following channels will go back to their original channel. 7, 9, 11, 13, 18, 28 & 34. The rest will remain on their second channel while their analog channel goes dark. I should call some of the stations like channel 5 to see if they will be changing their logo, since their second channel that they have been using is 31.

Make sure that when the big transition day comes, that you perform a channel scan on your TV or converter box. That way you will be able to view the channels that have made the change.

Channels assigned for Los Angeles:
7, 9, 11, 13, *28, 31, 34, 36, *41, 42, 43

Here are some documents to look at from the FCC.

Submission + - DTV Transition Begins Today for 421 Broadcasters

An anonymous reader writes: Ready or not, 421 television stations are still planning to terminate analog broadcasts today, trimmed down from the 491 broadcasters originally planned to switch. The Federal Communications Commission, broadcasters and others are working overtime to prepare consumers for the digital transition — and ensure that consumers who aren't ready for the switch will continue to have access to vital television news and emergency information. Of the nations nearly 1,800 full-power televisions stations, 220 will have terminated their analog signals before Tuesday and another 421 will terminate their analog signals on Tuesday before 11:59 pm, for a total of 641 stations, or about 36% of all full-power stations nationwide. The FCC has dispatched staffers to 72 markets across the nation where the impact is expected to be the greatest, while broadcasters who are shutting down analog signals intensify efforts to notify and educate the public.
