Linux 101 - detailed look on Linux History (1969 - 2015)

All modern operating systems that we currently use have roots that go back to 1969 when Dennis Richie and Ken Thompson developed C programming language and Unix operating system at AT&T Bell Labs.

By 1975, AT&T started selling Unix operating system commercially.

In the 80s, companies such as IBM and Sun started to create their own Unix operating systems (AIX created by IBM and SunOS which later is Solaris by Sun) and that resulted in a miss of Unix dialects.

The first real root of Linux was when Richard Stallman ended the era of Unix separation by starting the GNU Project and his goal was to make an operating system that is completely free and available for everyone.

In the 90s, Linus Torvalds wrote a brand new kernel (POSIX) and he put the source code online.

Today, more than 97% of world supercomputers, 80% of smartphones, 70% of web servers, millions of desktop and laptop computers and internet modems run Linux.

rmvb Vedio Compression

once upon a time, I was browsing my computer and I found out that I have 60 GB Movies saved on my laptop! Can anyone imagine the presence of that mount of storage on a 180 GB Laptop HDD reserved for Movies?
I Do believe in that because I know many people - like me - likes to watch movies on PC and specially on laptop.. - Try it while you are sleeping on your back and putting the laptop on your chest.
Anyways, all my movies are saved on the avi format which menas not less than a 700 MB files size. I had to cleanup some of my disk space t save it for installing Ubunto 10.4 so the less important data to delete were the movies. But before I proceed to delete them, I had a minute to think.. Is there a way to change the video FORMAT and compress them?!? Yes there is and that is what I found out at the end.
If you have 100 GB of avi videos and you want to free up 30 GB, you don't have to delete some f the movies.. the better thing to do is to use a special prgram which is able to COMPRESS the avi and decode it to rmvb format.
Fine, now lets talk about that special program.
The program I found is named Easy Real Media Tools!
Its a piece of cake to install software, very easy to use but it takes time to convert the video in order to keep the quality of the video. Also, you can use it to merge subtitle file which is the translation of the movie script to preferable language.
I shall add later some screen shots for

- Installation
- Configuration
- from avi to rmvb convert process

The program is free to use with no trial or limitations in features and you don't need to enter a serial or any of that crap.

What if you lost your Physical and logical HDD partitions by accedent?

I have a friend who had a strange issue with his PC. After booting up the Windows XP PC from a Linux Lite CD, he accepted some changes in his MBR due to the boot request but he did it to his HDD not the USB stick memory. After that, everytime he tried to do normal startup for his pc, he gets a message asking to insert a system desk and to presss enter. The regular solve for such a case is to check the Boot of the HDD using the Windows XP CD repair console. the first error message from the recovery console states that the C Drive is unreadable. now the status is the following; unpartitioned full size of HDD and needs to be partitioned and formatted. After some homework, I found out that there is a very helpful sftware which is Active@ Partition Recovery which is capable to do the following:

    1. If System Partition is deleted (where the operating system is installed,
       C: in most cases), i.e. machine is not bootable, your choices are:

        - Prepare bootable floppy/USB or CD-ROM, boot in DOS mode from the bootable
          floppy/USB or CD-ROM and use Active@ Partition Recovery for DOS to recover
          the system partition.

        - Attach damaged Hard Disk Drive to another machine bootable in Windows and
          having Active@ Partition Recovery for Windows installed, boot in Windows
          and recover the system partition.

        - Prepare and use Bootable Windows PE CD-ROM, boot from CD and use Active@
          Partition Recovery for Windows. You will be able to recover the system
          partition from the familiar Windows environment. Bootable Windows PE CD-ROM
          is supplied with Enterprise version only.


    2. If Non-System partition is deleted (for example D: or E: disk, or drive located
        on USB drive or Memory Card), i.e. you can safely boot your machine in Windows,
        your choices are:
   
        - Boot in Windows, install and run Active@ Partition Recovery for Windows,
           then scan unallocated space to detect and recover non-system partitions.

        - If for some reason you cannot detect partition or Windows does not allow to
           recover detected partition properly, prepare bootable floppy or CD-ROM,
           boot from it and try Active@ Partition Recovery for DOS to recover partition.

    3. If partition has been recovered, however Windows still cannot recognize it, it means
        that the file system itself is severely damaged you can try at least to save (copy)
        your files and folders located on the damaged partition to the safe place:
   
         - Use Active@ File Recovery utility to recover your files and folders from the
            damaged partition to the safe location. You can download this utility
            from the web site ( http://www.file-recovery.net/download.htm ) separately,
            as well as it is included in Enterprise version of Active@ Partition Recovery.

Friday after noon, I'm giving it a try and will update my post with the experience results.

The Result

I have tried the program and here are my results,

1- As long as you are working from the Bootable CD, you will be able to recover only 20-30 GB from the HDD which is generally the Windows System Partition.

2- After recovering the windows system, you will be able to log on normally to your OS.
3- Now you can run the Active@ File Recovery for windows and restore the rest of your lost partition(s).
