Comment Nettop itx ATOM board done right. (Score 1) 86

by csoh (#30521262) Attached to: Intel's New Atom D510 Benchmark Tested

Look at the picture of this board. Unlike typical atom330+945gc nettop board it has NO FAN. And if we recall the fact that 945gc chipset consumes 25w of power, way more than 8w cpu itself, I would rather call this board "Nettop ATOM board done right, powerwise". So if you already have netbook which uses 945gse mobile chipset(which is already power efficient), this would mean nothing more than minor facelift. But if you're going to buy atom330+945gc itx nettop board, this is much improved product to consider regarding power. And minor upgrade from gma950 to gma3150(slightly improved g31), would be better than nothing.

DoE Considers Artificial Trees To Remove CO2 418

Posted by timothy from the putting-the-artifice-in-artificial dept.
eldavojohn writes "CNN is running an article on a new angle of attack to reducing greenhouse gases. After meeting with the US Department of Energy on the concept, the researchers revealed the details that each 'tree' (really a small building structure in the concept design) would cost about as much as a Toyota and remove 1 ton of CO2 from the air per day. Don't worry, they're accounting for the energy the 'tree' uses to operate: 'By the time we make liquid C02 we have spent approximately 50 kilojoules [of electricity] per mole of C02. Compare that to the average power plant in the US, which produces one mole of C02 with every 230 kilojoules of electricity. In other words, if we simply plugged our device in to the power grid to satisfy its energy needs, for every roughly 1,000 kilograms [of carbon dioxide] we collected we would re-emit 200, so 800 we can chalk up as having been successful.' Each unit would remove 20 automobiles' worth of CO2 from the air and cost about as much as a Toyota... so the plan might be a five percent surcharge on automobiles to fund these synthetic tree farms."

Good Physics Books For a Math PhD Student? 418

Posted by kdawson from the queen-of-the-sciences dept.
An anonymous reader writes "As a third-year PhD math student, I am currently taking Partial Differential Equations. I'm working hard to understand all the math being thrown at us in that class, and that is okay. The problem is, I have never taken any physics anywhere. Most of the problems in PDEs model some sort of physical situation. It would be nice to be able to have in the back of my mind where this is all coming from. We constantly hear about the heat equation, wave equation, gravitational potential, etc. I'm told I should not worry about what the equations describe and just learn how to work with them, but I would rather not follow that advice. Can anyone recommend physics books for someone in my position? I don't want to just pick up a book for undergrads. Perhaps there are things out there geared towards mathematicians?"

That's why I always bring my oqo with me when travelling.

0. Assuming you have openvpn installed in always-on trusted gateway(home or office, windows or linux)
1. When needed ask/try to find just a network connection, not a public terminal.
2. Connect to your openvpn gateway pc. Don't do anything unsafe using normal network. If openvpn says something suspicious, don't use openvpn session and just use that network connection just for absolutely safe, casual activity e.g. viewing slashdot anonymously. Beware spyware.
3. When openvpn connected successfully, route all your internet traffic via your gateway pc using openvpn session.
4. Done. Other vpn solution also works, but openvpn is free, available for windows and linux, sniffing free, man in the middle attack free.

Submission + - Sony Films Won't Play on Sony DVD Players

Complaints have begun appearing on some tech websites that copyright-protection coding on new releases from Sony, including Stranger Than Fiction, The Holiday, Casino Royale, and The Pursuit of Happyness, has made them unplayable on certain DVD players. One person complained on an Amazon.com discussion board that when inserted in Sony's DVP-CX995V player, the disks "load up to the splash title screen and then load no further, then after about 60 secs the player turns itself off!" The writer said that when he contacted Sony he was told that the company was aware of the problem and that it was working on a firmware update. The writer then asked Sony, "Would it not be a good idea to test changes you intend to make on your DVDs at least on your own equipment so that if you find a problem you could have the firmware update available instead of not only inconveniencing, but alienating your own customers?"
