Comment: Synology + Notebook Drives (Score 1) 697

by mtgstuber (#29865915) Attached to: Low-Power Home Linux Server?

This will probably come in a little higher cost than you'd like, but consider getting a Synology NAS box (http://www.synology.com/us/index.php), and a pair of notebook drives. I've had a home server of one sort or another for years. Back in the day I had top of the line multiprocessor Compaq server with a full RAID array. These days I live completely off-grid. The power draw of that beast would crush me.

Seeking a better solution I picked up a 207+, and then modified the brackets to take a pair of notebook drives. I measured it at 12 watts. It doesn't have much processing power, but I run fetchmail, dovecot, slimserver, and of course file sharing services on it. It would easily run a web server, though I host my website externally. I have mine configured with cron to shut down in the at night. Newer versions have automatic support for starting up and shutting down based on the time. If you're not hosting a web site, you can save more energy and money.

For me, running a server without RAID or mirroring isn't an option. That's one of the reasons I chose this solution. I use a USB harddisk for occassional backups. I've never hooked a USB CD-ROM to it, though I don't see any reason you couldn't. It's running Linux under the covers, and it's relatively easy to cross-compile software for it, or simply use optware (http://www.nslu2-linux.org/wiki/Optware/Packages?from=Unslung.Packages) to get what you need.

PG&E Makes Deal For Solar Power From Space 392

N!NJA writes "California's biggest energy utility announced a deal Monday to purchase 200 megawatts of electricity from a startup company that plans to beam the power down to Earth from outer space, beginning in 2016. Solaren would generate the power using solar panels in Earth orbit and convert it to radio-frequency transmissions that would be beamed down to a receiving station in Fresno, PG&E said. From there, the energy would be converted into electricity and fed into PG&E's power grid."

+ - American Freedom Campaign: Testify or Impeach->

mtgstuber (457457) writes "The American Freedom Campaign has been pushing for a return to the checks and balances that preserve freedom in the US. Currently, Harriet Meiers, John Bolton, and Karl Rove, are all in contempt of Congress for not testifying before Congress. The Bush administration seems to be trying to just run down the clock, happily ignoring the subpoenas. Regardless of your political stripes, having the executive branch operate without a bad thing. The AFC is pushing a new campaign: Testify or Impeach, asking people to contact the White House and their Senators and Representatives and make it clear that we still believe in the constitution.
Side note to editors: I figure this will probably get deleted out-of-hand. Please don't. Slashdot is full of libertarians, Ron Paul supports, and techno-anarchists. As much as my inner geek really doesn't want to bother with politics at all, if people that care about freedom don't speak up for the constitution, it will continue to get watered down. Imagine the power of pointing slashdot towards this. We could really make a difference."

Comment: FCC restricts it to Law Enforcement (Score 2, Informative) 198

Oddly enough I read the FCC filing on this gadget for work earlier this week. It uses the 2.4 Ghz spectrum, but sends an analog signal -- not digital, which is what 2.4 is reserved for. Because it conflicts with the usage plan for 2.4 Ghz the only way the FCC would let them sell it was to specifically restrict it to law enforcement -- not merely government agencies. Personally, I wonder what will happen when these things are obsolete and sold at government surplus auctions, but at least for the next few years the only way you'll get one is if you have a badge.

Among other things, it'll stomp on your 2.4 Ghz WiFi lan. However, because it is designed for use in life and death situations, the FCC figures the police will have cleared the area, and you won't be hanging out surfing Slashdot.
