If you get a "permission denied" error, the file is not marked as being executable. To fix this: sudo chmod +x filename Example: In the above instructions, configure is th...

Want to try Google Android? Today is no longer necessary to have a mobile phone with Android installed to be able to prove it. Recently released a new version of Google Android LiveCD to test or install on a PC computer. Just download the ISO image of Live-Android that Google released for testing on a PC, burn onto a CD and boot the computer from this CD. Optionally you can also create a virtual machine with the ISO-Live Android, install and test it without rebooting the PC every time you want to use Google's operating system for mobile devices.

Here is the how to install the CentOS 5 Linux distribution on a pen drive (USB) using MS Windows. This will create a CentOS LiveUSB which can be run on any PC that allows booting (boot) from a USB port. That is, a true CentOS Portable. This works just like a LiveCD, the only difference being the boot from a LiveUSB is generally faster than from a LiveCD (if you have USB 2.0). Permanent configuration feature is not taken into account in this tutorial, so the changes you make in shaping the course of using the CentOS LiveUSB will be lost with every boot or reboot. CentOS is a Linux distribution based on RedHat Enterprise Linux and is aimed at businesses. Its use is very popular in web hosting server by its extreme stability. Because CentOS is based on RHEL, you can use the program Fedora LiveUSB Creator to install CentOS on a USB stick. Prerequisites to install CentOS to a USB flash memory: * A computer with Microsoft Windows installed (tested on Windows XP). * A USB pendrive or memory ...

Any compressed files extractor (Windows XP has native support for ZIP files). 3. Syslinux-XX.zip (where XX is the latest version). 4. dsl-xx-wmbedded.zip (where XX is the latest version) 1. Format the pen drive using the FAT32 file system. FORMAT X: /fs:FAT32 (where X is the drive of your flash memory) 2. Extract the contents of your dsl-embedded.zip in USB memory. 3. Extract the contents of Syslinux.zip to a folder called syslinux on the root directory of Win...
