If you’re eager to stay on the cutting edge of Firefox, head over to Mozilla to grab the newly released Firefox 3.1 Beta 3. As we mentioned last week, the next beta will be upped to Firefox 3.5 Beta 4 to reflect the many changes between Firefox 3 and this next major release. In the meantime, you can expect improved private browsing, JavaScript, and more with the latest release. Been living the 3.1 beta life already? Share how it’s been working out for you in the comments.
OK, this one caught me completely by surprise, because when I saw the thumbnail I thought it was an A/C duct.
My head spins at the thought of replacing one of these.

Two months after the SD Association announced the new SDXC (extended capacity) format, Pretec has unveiled the world’s first SDXC card with a capacity of 32 GB and read/write speed of 50MB/s. Future generations of these cards promise up to 2 Terabytes (2048 GB) of storage capacity and speeds of up to 300MB/s. Currently there are no products compatible with these memory cards.

Linux only: If you have ever tried to use the apt-get command to install software but received an error because you forgot sudo, the Command-line Fu site has a quick but useful tip for you.
The tip is one of those really simple, but extremely useful time-savers that might have just passed you by otherwise—instead of constantly typing “sudo” before each of the apt-get commands, simply use the alias function to add it there automatically:
alias apt-get=’sudo apt-get’
To make this change persistent across sessions, you will want to add this line to your ~/.bashrc file. Experienced readers will note that you can always use the sudo !! command to run the last typed command as root whenever you forget the “sudo” the first time.

side from having a really fast, non-filtered broadband connection, there are a few ways you can speed up your BitTorrent downloads through simple tweaks. The MakeUseOf blog runs down a few of them.
The MakeUseOf poster prefers Windows client uTorrent for its manageability and efficiencty—as do we, and our readers—but most of their tricks can be tackled in any torrent grabber. The list starts out with the obvious stuff, like choosing healthy seeds with lots of peers, and gets down into the nitty gritty, like increasing Windows’ allowance of “Max Half Open TCP connections” through a third-party patch:
After running the patch, you have to set the number of connections in your torrent client. For example, in uTorrent go to Options – Preferences – Advanced – net.max_halfopen. Set any number from 50 to 100. But see that net.max_halfopen is set lower than the value set in TCPIP.SYS. Always check if it is still patched because Windows updates sometimes overwrite it.

Windows only: If you like to keep a close eye on what changes new software installations make to your system, SpyMe Tools provides step-by-step snapshots of your registry and shows you what’s changed.
The in-depth review of your system registry that SpyMe Tools provides may be overkill for some people, but if you need to track changes or troubleshoot problems after certain installations, it can be invaluable. It’s simple to use: after you install the program, you run a system sweep with SpyMe Tools and save the results. After installing new applications or making system changes, you can compare the previous system state to the current one, and SpyMe Tools will show you all the changes. In addition to doing a before and after comparison of system snapshots, you can even run it in real time while installing software to see the changes as they happen.
If you’re interested in a more automated solution, check out previously reviewed Revo Uninstaller, a thorough application remover that our commenters frequently compare just about every system tool to (and that’s why we love you).
