There are plenty of wallpaper-changing applications out there, and plenty of them can tap into photo sharing sites like Flickr and Photobucket for access to a plethora of images. Still, not many of them are quite as well-connected as Wally.

Even fewer are cross-platform. Wally, though, is happy to share its background-rotating skills with Windows, Mac, and Linux users alike. It’s built using Nokia’s Qt4 framework and supports an insane number of image sources: local and remote folders (via FTP), and popular photo sites like Flickr, Yahoo!, Panoramio, Pikeo, Ipernity, Photobucket, Buzznet, Picasa, Smugmug, and Bing. You can use any combination of sources you choose by adding and removing them on the settings screen.

Customization options are plentiful, from specifying the delay between image changes to tweaking the size of your local image history store. Images from the ‘net are pulled in based on the search terms you specify – and yes, you can shut off Bing’s adult filter if you want to.

Wally is free and open source, and pre-compiled downloads are available for Windows, Mac, and Linux. The project is also mirrorerd over at Sourceforge.

64-bit versions of Windows 7, Vista, Ubuntu 9.04 and 9.10 fight it out for the fastest boot time on identical hardware.

Windows 7 is drawing raves from pretty much everywhere these days–many of which are the result of direct comparisons to its oft-derided predecessor, Vista. Windows 7 definitely seems to have Vista beat as far features, security, and ease of use go, but what about speed concerns?

We’ve seen some conflicting reports, in terms of system boot time, so these two guys decided to put the two OSes to the test. They loaded Windows 7 Ultimate 64-bit and Vista Ultimate 64-bit on two otherwise identical Lenovo Thinkpad T400s. Which system booted up faster?

The above video captures the second boot for both systems. They rebooted both computers a handful more times, and retried the test later in the day. You can see the decidedly different results below.

Want to turn your Windows installation DVD into an installation flash drive? WinToFlash can do that and more.

WinToFlash can transfer Windows XP, Vista, and 7 onto a flash drive as well as Server 2003 and 2008. WinToFlash can also transfer Windows Preinstallation Environments to flash drive.

The process is simple and mostly obvious. You tell WinToFlash where the installation files you want to transfer are located and either let the transfer wizard take care of things, or specify settings like what kind of format the flash drive will undergo. In our test using a USB 2.0 generic flash drive it took about 12 minutes to turn a Windows 7 installation DVD into a USB-based installer.

WinToFlash is freeware, Windows only.
