QiOO: Insert Holy Quran Verses in Your Document

Recently, I wrote about COOoder, an extension for LibreOffice or OpenOffice which allows us to beautify source code of many programming languages. Today, I'd like to inform you about an extension to put Holy Quran verses in your LibreOffice or OpenOffice document. Let's get started.

Downloading the extension
Make sure you have LibreOffice or OpenOffice installed on your system. Please download the extension here and select the latest version available.

Installing the extension
Inside the archive of downloaded file, you will find two files: font (*.ttf) and the extension (*.oxt). Before installing the extension, please make sure the font included in the archive is installed correctly. If you have no idea on how to install font in Ubuntu, simply type the following command:

• cp ScheherazadeRegOT.ttf ~/.fonts/
• fc-cache -f -v

Once the font installed correctly, now it's time install the extension. Please open LibreOffice or OpenOffice and navigate to "Tools > Extension Manager" then click "Add...".

Now, locate the *.oxt file you have downloaded.

Configuration
In order to make LibreOffice or OpenOffice displays Arabic text correctly (from right to left), we have to enable complex text layout. In LibreOffice or OpenOffice navigate to "Tools > Option > Language Settings > Languages", tick "Enabled for complex text layout" and select "Arabic (Saudi Arabia)" under CTL option.

Restart the application and you should be able to insert Quran text inside your document.

Boost Netbeans Start Up Time

If you are a programmer or a student who learns programming language especially Java programming language, you might know what Netbeans is. It is an IDE (Integrated Development Environment) for many programming languages. My favorite feature of Netbeans is its GUI Designer which let me design the user interface of my application easily. Unfortunately, Netbeans take long time to start. It takes 6.52 seconds to completely loaded. Well, I will give you a trick to reduce this loading time by up to 1.5 seconds. Let's get started!

Please find a file named "netbeans.conf". If you installed Netbeans via Package Manager, it's located in /etc/netbeans.conf. Otherwise, if you installed it by downloading the installer from Netbeans website it's located in installation_folder/etc/netbeans.conf.

Now, edit the file and find a line started with "netbeans_default_options". Here's the example:

• netbeans_default_options="-J-client -J-Xss2m -J-Xms32m -J-XX:PermSize=32m -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true"

Replace the above line with this one:

• netbeans_default_options="-J-client -J-Xverify:none -J-Xss2m -J-Xms32m -J-XX:PermSize=32m -J-XX:MaxPermSize=200m -J-Dapple.laf.useScreenMenuBar=true -J-Dsun.java2d.noddraw=true -Dsun.java2d.opengl=true -Dsun.java2d.d3d=false"

We turned off Java bytecode verification, making classloading faster, and eliminating the need for classes to be loaded during startup with -J-Xverify:none option. The "-Dsun.java2d.opengl=true" option is added for better graphic performance. It enables a new OpenGL-based pipeline for Java 2D used to support hardware-accelerated rendering using OpenGL.
For more options you can use to optimize Netbeans performance, please click here.

Regards :)
