I upgraded my site to the latest WordPress 3.2.1. When I browsed to the site for the first time after upgraded it, the screen displayed an error message indicating that WordPress 3.2.1 required 5.2.4 or above to work.
If you are have the standard PHP 5.1.x in CentOS 5.x and trying to upgrade your system to PHP 5.2.x using yum, you probably will encounter the same scenario where yum couldn’t find PHP 5.2.x package for update.
I searched around and found that PHP 5.2.x is included in the development repository.
Firstly, we need to add the development repository to yum. We need to add in the yum repository configuration file so it pulls PHP packages only. Use one of you favourite text editors to create a new yum repository configuration file.
# /etc/yum.repos.d/CentOS-Testing.repo
Copy/paste the following into this file:
[c5-testing]
name=CentOS-5 Testing
baseurl=http://dev.centos.org/centos/$releasever/testing/$basearch/
enabled=1
gpgcheck=1
gpgkey=http://dev.centos.org/centos/RPM-GPG-KEY-CentOS-testing
includepkgs=php*
Run the following command to get a list of what PHP packages you have currently installed in your system:
# rpm -qa |grep php
Use yum to update the PHP packages on your system by running the following command:
# yum update
Once yum has completed, run the following command:
# service httpd restart
Finally, if everything goes well, you have PHP 5.2.x running in your system.

PuTTY is a free Telnet and SSH client for Win32 and Unix platforms. It lacks the tabbing feature, which is one of the most important missing feature of PuTTY that many users are complaining. When you create multiple PuTTY connection instances, each instance will be opened in a separate window.
PuTTY Connection Manager is a free PuTTY Client Add-on for Windows platforms which provide a solution for managing multiple PuTTY instances by creating a tab for each PuTTY instance within the program window.
According to the features listed in the PuTTY Connection Manager web site, they include:

- Automatic login feature regardless to protocol restrictions (user keyboard simulation).
- Post-login commands (execute any shell command when logged).
- Connection Manager : Manage a large number of connections with specific configuration (auto-login, specific PuTTY Session, post-command, etc.).
- Quick connect toolbar to quickly launch a PuTTY connection.
- Import/Export whole connections informations to XML format (generate your configuration automatically from another tool and import it, or export your configuration for backup purpose).
- Encrypted configuration database option available to store connections informations safely (external library supporting AES algorithm used with key sizes of 128, 192 and 256 bits, please refer for the legal status of encryption software in your country).
- Standalone executable, no setup required.
- Localizable : English (default) and French available (only when using setup version, standalone is english only).

Agent Ransack is a free Windows tool for finding files and content of files on your hard drive fast and efficiently.
Agent Ransack displays the results of the text it finds when searching the contents of files so that you can quickly browse the results within the program without having to open each file separately.
I installed the software in Windows XP and Vista. I find the searching speed is much faster than the Search feature that comes with the operating system.

This site was upgraded to WordPress 2.7.1 without any problem. It took me about 15 minutes to complete the entire upgrade process, which included downloading the latest source file and backup the existing files.
I noticed the admin layout was different from the previous version 2.6 that I had. It took me a while to familiarize with the new layout.
Several plugins had newer version. I upgraded them with the upgrade automatically feature. Everything is working as it is suppose to be. What a relieve!
