ImageMagick is dealing with image processing (on the web) that used by imagick PHP extension. MODx, one of PHP popular Content Management Framework is using ImageMagick for its gallery module. My CPanel Server does not have ImageMagick, so I have to install it. My server uses WHM version 11.30.2 and I plan to install ImageMagick from WHM dash board. In WHM, I go to "Software" and then go to "Install a RPM". From RPM list, I install ImageMagick and ImageMagick Devel respectively. This step basically will install ImageMagick application. Then the second step, I install Imagick PHP extension. I go to "Software" and then go to "Modules Installer". After that I choose PHP-pecl menu by clicking the "manage" button. Input "imagick" into "Install a PHP Pecl" form then hit the "Install Now" button. And the final step is to restart httpd (apache) web server services. And thats all.

When I work together with my partners in my office, sometimes I should make some revision on a document that proposed by my partner. It is easy to modify the word document with Libre Office Writer, but I want to track what character, word or sentences that I have changed, so my partner can easily find my revision. In Libre Office Writer, after I open a word document, then I go to the "Edit" menu. From "Edit" menu, I choose "Changes" sub-menu and then give a check mark on "Record" sub-menu. After I do the above operation, I found that when I type a revision on the opened document, it will typed on orange. So my partner will easily find what I have revised. When I deleted a character, word or sentences, the deleted character/word/sentences would become a single strikethrough character/word/sentences. So, it easy to collaborate with other staff using Libre (Open) Office Writer.

Just for experiment, I install IPFire router firewall in virtual box inside my PC that running Linux Mint Debian Edition. IPFire is a wellknown router firewall linux distro today. In my opinion, IPFire is more like IPCOP router firewall, but has more integrated modules in default installation. The installation process is more like IPCOP. IPFire easy to use and administered through its web admin page. Since my PC only has on ethernet card, so I missed the RED network configuration, but all install process is completed. The RED interface can be setup later by running setup command. See the installation process video on Youtube.
