High level language and Low level Computer language

Difference between high level language and low level language

High level languages allow much more abstraction than low level languages. This allows algorithms and functions to be written without requiring detailed knowledge of the hardware used in the computing platform. The compiler provides this interface transparently for the programmer.
 

Examples of high level languages include C, C++, Java, etc.

Low level languages will require more involvement with the actual register and interrupt interfaces to the hardware. This can provide more control and efficiency for the program and can be good for applications which need high speed execution, but high level compilers are much better at optimizing for speed now.


Examples of low level languages include machine language specific to each processor and assembly language specific to each processor.

Customizing the splash image in Bootloader

Customizing the splash image in Bootloader

The splash image is the image shown in the background when GRUB (the Grub Shell) is displaying the list of operating systems you can boot.
Normally, this is the corporate logo of your Linux distribution. But its very simple to customize it to an image of your choice.
All you need is the GIMP and gzip.
For this you have to follow the simple steps
firsty you need root access and follow the simple steps

1)Start the GIMP.

2)Click on File->New or type Ctrl+N

3)In the new image dialog, change Width to 640 pixels and Height to 480                  pixels. (The image should be of size 640x480 pixels.) Now click OK.

4)Create the image which you would like to be the splash image.

5)After you have finished creating the image,
    hit Alt+i or right click on the image and click on Image->Mode->Indexed...

6)In the Indexed Color Conversion dialog that appears,
    click on the radio button "Generate optimal Palette" and
     in "# of colors" enter 14. Click OK.(The image should be of only 14 colors)

7)Now right-click on the image and click on File->Save As...
     Save the file as  splash.xpm in a directory of your choice.

8)Now open a terminal window and navigate to the directory where you have
     saved splash.xpm

9)Now key in gzip splash.xpm

10)You will find that a file named splash.xpm.gz is created in the directory
     where splash.xpm used to exist.

11)Copy this splash.xpm.gz to the /boot/grub directory.
     You may want to back up the pre-existing splash.xpm.gz file in
      the /boot/grub directory first.

That's it! When you reboot, you will find your image in the background, with the menu of operating systems etc. in the foreground.

Change Login Screen On Fedora 14

I’ve been doing some tweaks on the machine I set up with Fedora 14 (Laughlin) using Gnome. Things were OK until I decided to change the login screen image. I did a Google search and found a solution that didn’t work for me. I have also read from forums that there was no way to change the image unlike the earlier versions of Fedora. I then had this idea of finding the image used as the login screen background and overwriting it with my preferred image. 

So I checked the “/usr/share/backgrounds/” directory and found a “laughlin” folder. Inside it is a folder named “default” that contains three other folders named normalish, standard, and wide and a laughlin.xml file. The three folders contained the default login screen image.

If you open the xml file with a text editor, you’ll notice that a part of it specifies the path of the Laughlin wallpaper. Wide, Normalish, and Standard specifies the image dimensions. And using this xml file, we can change the login screen image.

                                             Laughlin XML File

Here’s what I did. First, I edited my image three times using the specified dimensions (this is optional) and saved them as PNG files. I then copied them to the three folders with respect to their dimensions.

Firstly go to super User and then follow the steps as per your need 

# cp /current/file/location/filename1.png /usr/share/backgrounds/laughlin/default/wide/

# cp /current/file/location/filename2.png /usr/share/backgrounds/laughlin/default/standard/

# cp /current/file/location/filename3.png /usr/share/backgrounds/laughlin/default/normalish/

Using vi, edit laughlin.xml and replace the filenames and save the file. See image below.

Edited Laughlin XML File

I logged off and there was my new login screen.

Skype in Fedora 14 X64

Install  Skype in Fedora14  64bit?
As we know, there is  no  Skype 64bit  available,
So here we use i686  packages to install skype in 64bit.
Our current system is :

[LINUX@fedora-home ~]$ uname -a
Output:
Linux fedora-home 2.6.35.6-48.fc14.x86_64 #1 SMP Mon Nov 29 15:36:08 

UTC 2010 x86_64 x86_64 x86_64 GNU/Linux

To install Skype 32 bit in a 64 bit system we need to install some dependencies using yum:

yum  install libXv.i686 libXScrnSaver.i686 qt.i686 qt-x11.i686 

pulseaudio-libs.i686 pulseaudio-libs-glib2.i686 

alsa-plugins-pulseaudio.i686  -y

Now  download  Skype  from official website and install the rpm package

rpm -ivh skype-2.1.0.81-fc10.i586.rpm

And now
Njoy SKYPE
