Firefox 3 and dark themes
A few dark GTK themes show how to fix the resulting Firefox's dark textboxes and forms, however those fixes don't work with Firefox 3. After a bit of googling I found an Arch Linux thread that provided a solution. Since I couldn't find anything on Ubuntu Forums I thought I would post it here.
Step 1. Install the Stylish Add-on
**notes on using Stylish **
The next 2 steps need you to create Styles in the Stylish add-on.
To do this you can:
A. Click on the stylish icon to the right of the status bar > Manage Styles > Write

Configure CPU scaling to decrease heat and increase battery life
This guide should work with Ubuntu Feisty or Gutsy 32 bit. Most of the guides that I have read on this subject way over complicate things and don't give information on how to change the scaling governor. So as requested by several other forum members here is a howto.
About CPU Frequency Scaling
You may have noticed the CPU Frequency Scaling Monitor that you can add to your Gnome panel. It gives you information about the speed of your processor if your processor has scaling abilities. Most notebook processors have this ability. To see which speeds your processor can run at, you can run this command:
How to Optimize your Internet Connection in Ubuntu Linux
The TCP Maximum Transmission Unit (MTU) is the maximum size of a single TCP packet that can pass through a TCP/IP network.

Source: http://news.cnet.com/8301-13505_3-10002957-16.html

It opened the door a bit more in April when it opened up QuickBase to developers, but now seems to be paving the way for a more complete launch into open source with its Linux Business Resource Center.
Yes, that Intuit. Promoting Linux and open source.

Launched yesterday, and available now in Debian "experimental," KDE 4.1 is what 4.0 should have been, one reviewer finds. With some 70,000 software changes since 4.0 launched at Google HQ last Jan., is KDE 4.1 about to usher in the future of the Linux desktop?
Insanely Securing Your Unix or Linux Systems

Hey again,
Since this week has been all over the map, I thought we'd spend today going back and dipping into the over-the-top-security well ;) You may recall a post from last year that we did on making generic user accounts su-only and, maybe even more so, a post we just recently did on using mkfifo and script to keep tabs on user account usage. Both of these were aimed at providing relatively decent security for the Unix or Linux admin, while allowing the user the freedom to do his or her job without too much of a hassle.
