 Step1: Go to Terminal.

            Type the following,
                   sudo apt-get install ia32-libs 
Step 2: Now the packages will be downloaded and installed

             Go back to terminal again and run the following command,

Installing XAMPP on Ubuntu 12.04 LTS 64bit to run PHP/Perl Scripts

, 0 comments

XAMPP, as we all know is an open source web development server solution and consists of Apache, MySQL, and is widely used to run and test programs and scripts written in Php and Perl. Here is a tutorial on how to install XAMPP on Ubuntu 12.04 LTS.

Step 1: In Terminal, log in as root by entering the following command.
sudo -s
Step 2: After logging in as root, download the latest version of XAMPP - xampp-linux-1.8.1.tar.gz.

Step 3: Copy the downloaded file to the home folder and extract it using the command
tar xvfz xampp-linux-1.8.1.tar.gz -C /opt
Step 4: Now XAMPP has been installed and all you need to do is start the XAMPP service, which can be done by the command.
/opt/lampp/lampp start
Step 5: Now open up your browser and type http://localhost which will open up the XAMPP Dashboard. You can delete the index.php file in /opt/lampp/htdocs to disable the dashboard screen. 

Step 6: Copy your PHP/Perl scripts to the /opt/lampp/htdocs folder to open and run it from localhost. 

More XAMPP commands and functions can be found here.

We strongly recommend XAMPP over WAMP.

Installing Linux from a USB Pendrive

, 0 comments


Linux on an USB drive.
This is a tutorial on how to install a version of Linux from an iso file by booting it from an USB Pendrive. In this tutorial we are going to help you install the latest version of Ubuntu, The Quantal Quetzal. We prefer you use a 64bit version if you have more than 4GB of RAM available.

  1. Download the version of the Linux iso file you want to install on your PC. 
  2. Download and Install 'LinuxLive' (LiLi) , a software to write the iso file into the USB drive.  - Download.
  3. After installing LiLi on your PC, open it and follow these steps in order,
  4. In Step 1 on Linux Live, Select the USB drive on which you want to boot linux from.
  5. In Step 2 select 'ISO/IMG/ZIP'.
  6. At Step 3 select Live mode to use it live and install it. Add very little persistence memory if you wish to install.
  7. In Step 4, select to hide files in USB drive and format the Pendrive.
  8. Now after a while a small text will appear at the bottom of Lili, saying the LinuxLive key is now up and ready.
  9. Now restart your PC, go to BIOS and change Boot Priority to USB and reboot.
  10. Now your PC will boot from USB drive and you will be shown options to install Ubuntu.

ou
The user interface of LinuxLive and the steps involved.

You can also use other softwares like UNetbootin, Universal USB Installer and a few other softwares to write your image(.iso) file to a pendrive. We prefer LiLi as we find it quite simple and attractive. You can find a list of other software which can write image file to USB drive here at alternativeto.net/software/lili-usb-creator.

The new Samsung Galaxy Tab 2 P3110 preview and specifications

0 comments

Tab 2 P3110
Samsung is rolling out a new product into it's tablet range, the new Samsung Galaxy Tab 2 P3110 which is very similar to Samsung's earlier tablet Tab 2 P3100 which offers call facility. This tablet though doesn't offer call facility to it's users but is priced almost 6k less than it's predecessor.

The P3110 packs a 1Ghz dual core processor which packs 1GB of RAM to run the latest Android 4.1 Jelly Bean OS. With the PowerVR SGX540 graphics card the tab is capable of handling a lot of action packed games. A 7inch LCD Capacitive screen touch screen with a resolution of 1024x600 and 16M colors may not stand-up with the best but is justified for the price the P3110 is being offered. 

The tab has an internal storage of 16GB and is expandle upto 32GB using a microSD card. A 3.15 Megapixel primary camera which is capable of recording even 720p videos at the rate of 30frames/sec isn't really an asset as it doesn't have autofocus but given the price you cant ask for more, and the tab also has a secondary 0.3 MP camera, which we feel is unwanted as there is no calling facility available for this tab.

A 4000mAh lithium-ion battery is where the P3110 draws it's power from and has a standby time of around 1070 hours. The P3110 Samsung Galaxy Tab2 is more or less the Tab P3100 minus the calling facility.  We would list the pros and cons of the Tab P3100 and a few others so that you can have an idea of what you are going to get,

Pros
--------
  • Dual core processor and 1GB Ram.
  • Android 4.1 Jelly Bean OS.
  • The PowerVR SGX540 graphics card.
  • Good multimedia support.
  • Decently priced at Rs 13,990/-
Cons
---------
  • No gorilla glass feature.
  • Not the best of displays with a comparitively low PPI(Per-pixel intensity).
  • A meaningless front camera when you don't have calling facility.
  • No USB charging and long charging times.
We would recommend the Galaxy Tab2 P3110 to people who are desperate to get a decent tab at around 10-15k and who doesn't mind not having the calling facility feature. Go for it only you are ready to sacrifice on these things.
