Linux CentOS 5 Server: YUM Repository to Install Zend Optimizer

I recently needed to install Zend Optimizer which was required by a ZenCart addon using Zend Guard. Zend Guard encrypts some or all of a PHP application to help protect its contents from being copied or modified. So I was typically like to install everything on CentOS using the yum package manger to make sure that updates for all applications are uniform and easy to do.

The actual package that needs to be installed to install Zend OptimizerĀ is called php-zend-optimizer and isn’t readily available in many yum repositories. On a typical CentOS installation I add a couple extra yum repos including rpmforge and a repo that provides ruby based packages for CentOS. Anyhow after awhile of searching I finally located the atomic repository which did include the php-zend-optimizer package.

Delete All Mail Using the mail Command From the CLI of a Linux Server

Deleting mail from a Linux users local account is easy using the mail command line utility. The mail command can also be used to perform any other functions that you can think of to manage email such as replying to messages, reading messages, or just sending messages. It is very basic in nature but it does provide a great utility for simple mail tasks.

Typically most of the mail that ends up in a user account on a Linux server that I might manage comes from a cronjob or some various task that is run on a server under a users name. It is important to understand and review these messages from time to time as they may have important information in them.

Install Tabbed Windows Explorer Toolbar For Browsing Multiple Folders From One Window

Almost everyone has become used to tabs for their Internet browser. Applications that incorporate tabs make life a lot easier and cleaner for that matter. I have become used to tabs for my SSH client, tabs for Internet Explorer, tabs for Console, tabs for Trillian, etc. One thing I have always wanted but never took the time to look into though was tabs for Windows Explorer. I am constantly in various folders comparing files or moving files between folders and typically have 3 to 4 Windows Explorer windows open at all times. Well I finally decided to take the time to look for a solution and was pleasantly suprised to find QT TabBar from QuizoApps.

Skype: Get a List of Voicemail, Delete Skype Voicemail

The newer versions of Skype, which include version 4 and above, appear to not provide a way to list or delete voicemail messages. There are two options I have come up with to resolve the issue of managing Skype voicemail messages. I would think that Skype will resolve this issue in the near future however it has already taken longer than I would have thought to provide a solution to users to manage voicemail. I am currently running Skype version 4.0.0.226 so the below information is based off of that Skype version which at the time of writing this article is the most current. I recommend using option two which includes a third party piece of software so you still get the benefits of the latest release of Skype.
