Been so buys buying smaller media companies that you haven't had time to keep up on the week's news? Here's what you've been missing, CBS, Condé Nast, and Comcast:

• Thunderbird 3 alpha 1 available now
  Firefox may get all the attention, but Mozilla's Outlook-clone/killer also shows that open source software can hold its own in the instant messaging space. This week saw the release of Thunderbird 3 alpha 1, which uses the Gecko 1.9 rendering engine, adds support for tabs, and a ton of other tweaks.
• OpenSolaris 2008.05, and other places the sun don't shine
  Sun released the open source version of its Solaris operating system this week. It's pretty, features the Gnome Desktop environment that should be familiar to Linux users, and is incredibly difficult to get working on common software. Join us for a romp through the world of OpenSolaris. You'll laugh, you'll cry. You'll thank us for trying it out so you don't have to.
• Torrent2exe turns any torrent file into a single-source BitTorrent client
  Ever try to explain to a friend how BitTorrent works and then suggest they download uTorrent just so they can download some large file from the web? Turns out there's a way to avoid that confused look on their face. Just grab the torrent file, upload it to Torrent2exe, and you'll get a single executable file that you can give your friend. When they click, the file will download just as easily as if they'd clicked a download link in their browser. You know, as long as someone's seeding it.
• Microsoft launches WorldWide Telescope public beta
  Why spend time gazing at the stars in your backyard when you could sit in front of your computer instead? Microsoft's WorldWide telescope lets you navigate they sky just as easily as Google Earth lets you navigate the earth. The software also features guided tours from astronomers and tools for controlling a telescope plugged into your PC.
• Monitor your hard drive usage with DriveSpacio
  Right click on a drive or folder in Windows and you can find out how much space it's taking up. But Windows doesn't do a great job of showing you which of all your folders are using the most space. DriveSpacio is. Enough said.
• Splashtop Linux interface coming soon to every Asus motherboard
  Imagine being able to surf the web or make a Skype call within seconds of hitting the power button on your PC. Pretty soon, you may be able to. No, Microsoft Windows 7 won't feature instant-on capabilities. But motherboard maker Asus plans to add an instant-on Linux-based OS to a million motherboards a month starting pretty soon. While you're waiting for Windows to boot in the background, you'll already be able to use your PC.

DriveSpacio is a free Windows utility for examinging hard drive usage. When you first boot the program you'll get a list of each hard drive and partition on your system, along with, some details like the files system, cluster size, and a pie chart or bar graph showing used and free space.

But the fun really begins when you click on the Folders section. You can choose a folder, or an entire drive (just click C: or E: or what have you in the browse window), and DriveSpacio will plot your folders on a graph showing you which of your folders are eating the most space. It taks a few moments to scan folders with a lot of subfolders or files, but the result is a pretty effective tool for figuring out why you're running out of space on your hard drive.

WinDirStat is another free utility which does pretty much the same thing. But if you prefer the bar graph/pie chart look to WinDirStat's more abstract-looking visualization, DriveSpacio is worth a look. But there is at least one area where WinDirStat holds the edge: while you can delete files from the WinDirStat interface, DriveSpacio only shows you file and folder names. It doesn't let you launch or delete files.
