I was working on a Linux system that is running Fedora Core 4 and needed to install some updates to the system. I was using YUM because of the easy of use and how well it handles dependencies with rpms.

When trying to update the system I received the following error:

[root@yourlinuxbox ~]# yum -y update php

Cannot find a valid baseurl for repo: updates-released

We discussed earlier about how to rename a bunch of files in Vista, but what if you want to rename a group of files with names that discribe each one? Suppose you have a bunch of photo that you took with your camera and they have been named something like DSC_0001, DSC_002 and so on. Good news, you don’t have to go through the “right click and Rename” process each time.

When troubleshooting problems with various devices and components, there will be times when you would like to see information such as the hardware ID of the device or other information that is not available by default in Device Manager. You can configure Device Manager to display more detailed information.

At some point you may need to rename a bunch of files at once on your computer. This is a simple little trick for renaming files in a batch on Vista using a common file name and numbers added in sequence automatically.

The latest standard for wireless networking is 802.11n that clocks in speeds of above 100Mbps. If you’ve upgraded your wireless networking equipment to 802.11n you may not have experienced the performance boost you were expecting. By default, Windows XP is not optimized to handle this increase in speed. You can edit the registry to turn on a feature called Receive Window Scaling that will help XP take advantage of this speed increase. As always, back up the registry before making changes.
