NatGeo Downloader 2.0 Grabs Over 5,000 Wallpaper-Worthy Photos [Updates]

Source: http://feeds.gawker.com/~r/lifehacker/full/~3/4T_Uq-lAFLk/natgeo-downloader-20-grabs-over-5000-wallpaper+worthy-photos

Windows: National Geographic's web site has some stunning photography, and a lot of it makes for good rotating desktop backgrounds. The NatGeo Wallpaper Downloader we've previously enjoyed has updated with interface improvments, bug fixes, and access to thousands more images.

The app's developer writes that while his first release of the app made it convenient to grab a few hundred of National Geographic's photography contest images, this 2.0 version broadens your access to more than 5,000 images. Future versions should expand the range even further. It's a Windows-only app, but Linux and Mac users with some command line savvy can still get in on the NatGeo action.

NatGeo Wallpaper Downloader is a free download for Window systems.

NVIDIA's Optimus technology shows its graphics switching adroitness on video

Source: http://www.engadget.com/2010/03/03/nvidias-optimus-technology-shows-its-graphics-switching-adroitn/

Explaining automatic graphics switching and the benefits thereof can be a somewhat dry affair. You have to tell people about usability improvements and battery life savings and whatnot... it's much more fun if you just take a nice big engineering board, strap the discrete GPU on its own card and insert an LED light for the viewer to follow. NVIDIA has done just that with its Optimus technology -- coming to a laptop or Ion 2-equipped netbook near you -- and topped it off by actually pulling out the GPU card when it wasn't active, then reinserting it and carrying on with its use as if nothing had happened. This was done to illustrate the fact that Optimus shuts down the GPU electrically, which is that little bit more energy efficient than dropping it into an idle state. Shimmy past the break to see the video.

How to Manage Passwords In Any Browser And On Any OS [Security]

Source: http://feeds.gawker.com/~r/gizmodo/full/~3/Hye9s6FhngI/how-to-manage-passwords-in-any-browser-and-on-any-os

I want a universal password manager—something that can work with any browser and any OS—and I want it to be simple, secure, and completely dummy-proof. Turns out that such a thing actually exists. Meet LastPass.

Lifehacker's Kevin has a great guide to how LastPass works and how you can get the most out of it, but here's one of the most important things to keep in mind:

[T]he only thing stored on LastPass' servers is a heavily encrypted bundle of your passwords and the sites they belong to-a form of host-proof hosting. They don't have the encryption key to your passwords (only you do), and the encryption and decrypting all takes place on your own computer, where a backup copy of LastPass' records is always kept. If LastPass became evil, or got hacked, the nefarious doers would have to buy one of Google's server farms to break into its users' passwords.

Sold? I am and will be giving LastPass a shot. You can read all about the password manager's features such as browser extensions, one-time passwords, bookmarklets, secure notes, and mobile app compatibility over at Lifehacker. [Lifehacker]

Backpack Power Plant: You ARE the Grid [Energy]

Source: http://feeds.gawker.com/~r/gizmodo/full/~3/OiMI8nEl6pA/backpack-power-plant-you-are-the-grid

Bourne Energy's BPP-2 puts a 30-pound, 500-watt generating hydroelectric plant on your back. That's like being able to walk around with 60 solar panels. And when civilization finally collapses, I'll be dragging mine to an as yet undisclosed location.

You can use the Backpack Power Plant in any stream deeper than four feet. It also operates silently, with no heat or exhaust emissions, and can be "bottom-mounted" for total invisibility: all good things for hiding from the roving hordes of the post-apocalyptic dystopia. The set-up is pretty straightforward as well:

To install the civilian BPP, you would dig two trenches on opposite sides of a river and insert a lightweight anchor into each. Then, you'd run a synthetic rope between the anchors and the BPP. [The] company designed the system to work like the high-tension mooring systems that hold up floating oil rigs.

There's a military version already in use that can operate in a variety of flow rates, but the $3,000 civilian edition is designed for streams moving 7.5 feet per second. The main target audience is developing countries, where a portable generator of this magnitude could make a huge difference for remote villages and towns.

It's a prototype for now, but you and I both know they've got a hard deadline of 2012 if they really want this thing put to good use. [Wired]
