how to mount .iso files manually on ubuntu-9.10-karmic

what is iso image??

It is a compressed archive file that includes all the data files. It is defined by International Standard for Organisation(ISO). It has ".iso" file extension and the same image file can be burned on CD/DVD's

How to mount ISO file on my Ubuntu 9.10 Linux / Other Linux box's ??

On recent ubuntu linux mounts iso files automatically when u double click the .iso files. Otherwise you can mount iso manually.

$ sudo mount -o loop <ISO file path> <mount point>


How to un mount ??

$ sudo umount <mount point>

When you are trying to unmount you will often get some errors like this:
----------------------------------------------------------------------------------
arun@arun-laptop:/mnt$ sudo umount /mnt/
umount: /mnt: device is busy.
        (In some cases useful info about processes that use
         the device is found by lsof(8) or fuser(1))
----------------------------------------------------------------------------------

Check whether you are still accessing the mount point.If so come out of that directory, then try un mounting the mount directory.

OR

Here iso file being mounted as "loopback device". you can identify the mount point using " $ mount" command

i.e. dev/loop0 on /mnt type iso9660 (rw)

unmount it using this command, here loop[1-9]
$ sudo umount /dev/loop0

Android

what is Android ?? Any guess...

Yes by definition "Android" means "an automaton that resembles a human being"

Not only that geek..it is a Mobile Operating System running on Linux kernel and it is the first Mobile OS that is running top of the Linux kernel.

Android project was started by Go-ogle and Open Handset Alliance, later they released it as a open source project for mobile phones. Android running its applications on top of Dalvik Virtual Machine(DVM) completely rewritten in java for mobile platforms.


Here Linux kernel sources are released under GPLv2 license and application sources are released under  Apache licenses

Android also released its API to the developers explore more through Android SDK. There are three major SDK release from Android development team: SDK-1.1 release 1- February 2009 , SDK-1.5, release 3- July 2009 and SDK-1.6 Release 1 September 2009, then now Android SDK-2.0 release 1- October 2009. You can download and install SDK on your Linux machine for installation instructions click here .

Write your own application for android and post  the application on market place get money.


Android was initially targeted to run on ARM(RISC architecture) platform then later they made it to run on x86(CISC architectures) platforms. There are plenty of mobile phones and net book's are going to come in market. HTC released his G1 mobile that is powered by Android and also Asus eeePc running on Android. :(-
