This Guide Contents 1. Preparing Your Development Computer and Install Required softwares 2. Install Andoid SDK 3. Install ADT Plugin for Eclipse 4. Configure Eclipse and Install Latest Android SDK with AVD Manager 5. Create Simple Android Test Project 1. Preparing Your Development Computer and Install Required softwares 1.1 Install Sun/Oracle Java 7 JDK/JRE 1.2 Install Eclipse SDK 3.7 (Indigo)## 2. Install Andoid SDK 2.1 Change root user su - ## OR ## sudo -i 2.2 Download and Install Android SDK ## Select place to download cd /tmp ## Download Android SDK r16 package for Fedora, Red Hat (RHEL) ## wget http://dl.google.com/android/android-sdk_r16-linux.tgz Note: Latest SDK r16 (Android 2.3 Gingerbread and 3.x Honeycomb) emulator is currently working only with Glibc 2.7 or greater, so that’s why CentOS 5.7 and Red Hat (RHEL) 5.7 needs a newer version of Glibc to run Android SDK tools. This is possible to get working with manually build GNU C Library (glibc) 2.7 or later on CentOS 5.7 or Red Hat (RHEL) 5.7, but this might cause much problems and that’s why here is not now guidance for that.
LAMP (Linux, Apache, MariaDB/MySQL, PHP) server is very powerful server setup behind any website or web based service. This guide is collection of Fedora/CentOS/Red Hat (RHEL), Apache, MariaDB/MySQL and PHP install guides.
Today the Internet is full of instructions, which promises a LAMP server installation with a “One-Liner”, and so forth. In fact, these “One-Liner” instructions assume that, Linux is already installed and installs just AMP (Apache, MariaDB/MySQL, PHP) pakages, without any configuration. AMP programs can be installed with one command easily, of course, but the correct configuration have to be done anyway, especially if the environment is going to production use.

This is quick tip, howto list contents of tar, tar.gz and tar.bz2 files without unpacking file.
This is very useful on server environment where any graphical tool is not available. This method is also very useful when tar, tar.gz or tar.bz2 packages are really big, something like hundreds of megabytes or gigabytes (for example backups).
Overall, the key is the tar command with -t option.
