Because if you’ve ever looked at the details while your computer is starting up, then you’ve noticed that it spends a lot of time figuring out your network connections (both wired and wireless if you’re on a laptop). It seems contradictory to disable them from the startup, but your network connections will still work when you get to your desktop. Although I don’t understand it 100% myself, I believe that the Network Manager program is already in control of the networks, so just let it do it’s thing. Let’s get to it:
1.) Open the sessions manager:
Goto System -> Administration -> Services.
2.) Ensure that Network Manager is enabled:
In the left panel of the services manager, ensure that there is a check mark placed next to “NetworkManager” and “NetworkManagerDispatcher”.
3.) View all “Runlevel” services:
Click on “Edit Runlevel” and select “runlevel all” or simply press “ctrl+0″ on the keyboard.
4.) Disable the “network” service on all runlevel services.
Ensure that there is no check mark next to the service called “network” on all runlevels.
5.) Enjoy!
This trick should save you some time on startup like it did for myself.

It should be easy, but unfortunately, you were met with a nasty “object reference not set to an instance of an object” message. This happened to me in F-Spot version 4.0. So, to investigate, I followed these bugs:
bug #484188
bug 304124
Bug 463789
Upon extra research, I stumbled across a post with an interesting observation. It seems that if the pictures were once in F-Spot’s catalog and then tagged while the option of “Write metadata to file” was enabled, then it would cause the aforementioned issue to occur. I’m pretty sure that’s exactly what happened in my case, but anyways, onto the fix!
Basically, the problem has been fixed in the newest version of F-Spot (0.4.1 released 12/4/07) and it just needs to be upgraded to that. To do this, just use this command in the command line:
sudo yum --enablerepo=development update f-spot.i386
Enjoy!

I just wanted to show these cool graphs that were made with the help of an open source mathmatics program called SAGE. It’s main goal is to “reinvent the car instead of just the wheel”. In other words, the goal is to reinvent a program that will be capable of performing the same calculations as Maple, Mathmatica, as well as other major software companies. The good news is, it will always be free and cross-platform! Which means it’s available to Windows, Linux, and Mac OS folks alike.
