virtualization a new approach (repost)

To look at the options to provide a virtual machine to run windows on Linux.

i had multiple options

Complete virtualization (virtual machine)

1) Bochs (I have used it a few years back and found it good, but it only lacked a graphical configuration manager)

2) VMWARE (one of the best in terms of ease of use but i have to reject it in due to its licensing)

3) XEN (text on net says a lot about it but till now i am unable to establish a xen server what i want to do is to set a windows guest but i have not found an option for it till now.)

then a site came into view the screen shots seems quite impressive and so came the fourth option in my mind

4) innotek virtualbox (although its proprietary in its fullest, but a limited version is also released in GPL, and both versions are free for educational and not for commercial use.)

See more about the latest version of virtualbox here



5) Wine – a nice piece of software, till now i have been able to succesfully run

i) macromedia dreamweaver 8.0

ii) adobe photoshop cs2 tryout

iii) winzip, winrar and other compression tools

iv) AVR studio 4

v) WinAVR

vi) Boson Netsimulator

vii) need for speed II SE

viii) AVRlibs


Well i have been dieing to try my hands on those nice games available to me during the good old days of dos, which includes jazz jackrabbit and others which i was unable to on XP, even under compatibility mode.

This nifty utility is now installed on both my windows and Linux box and is helping me run those old applications which worked on dos only (or at most win98) environment.

roundup : year 2007

well so this last day of december marks the end of 2007.

so how about a roundup

on GNU / linux front

i think a lot is already covered in

besides few morethings that needs attention are

release of Debian GNU / Linux 4.0

this release is the most waited release of the series coz it featured the firs t of its kind GUI installer which was running not on XORG but on framebuffer hence reducing the ram usage to bare 32MB’s as compared to min 128-256 of today’s distro’s

Debian made a point in the start to keep its o.s for lowest config as well as highest config,

still its apt-get system is best (yum tries to emulate it but is not that good when it comes to application base)

WE saw a lot of changes on indian O.S develoment front also with indian education centers like CDAC entered the O.S. market with the launch of B.O.S.S. (Bharat operating system solution). a custom debian distro, specially designed for indian people.


on web front a lot has changed

a lot of acquesition’s from search gaint google,

and then hotmail fame sabeer batia comming back in social networking bussiness with apnacircle, which does started out good with few prizes to offer but as offers’ gone so is the public, also his original charm was missing here and a lot of content seemed copied from either facebook or linkedin or orkut.

paypal started its virtual credit cardscheme corrently avialable t us only, but will expend soon.

linkedin added photo features and had some problems with its gmail contact setting (already covered on this blog)

on some perosnal fronts

got my name listed more prominently on google for both “anant shrivastava” “techno enthuiast”also got a premium listing in google for my full name.

got my paypal account move over 10$ limit, previous highest was 3$, in last 40 days of 2007 i have earned 25$. those who want to know how can contact me perosnally i am not going to go open mouth about it. it’s for the work which is technical for a lot.

Google Launches Android

after the unofficial acceptance by google authorities earlier. Google has today launched its mobile application development platform ANDROID

This mobile platform has a lot of new things including but not limited to
1) Open Access through standard API calls even to the core mobile functionalities
2) On of the most intersting feature i liked is its non discriminative nature — even the dialer or home screen can be replaced.
3) As always google is now targeting mobile users and in order allowing desktop applcations to migrate to mobile level.
4) Complete SDK also includes device emulator and advanced debugging tools.

We have seen the growth a platform can get with the open developer’s involvement (simple example is Facebook), and hence came the google android chalange a $10M Challange for the best android apps.

As per android challange site

Cool apps that surprise and delight mobile users, built by developers like you, will be a huge part of the Android vision. To support you in your efforts, Google has launched the Android Developer Challenge, which will provide $10 million in awards — no strings attached — for great mobile apps built on the Android platform.
How It Works

The award money will be distributed equally between two Android Developer Challenges:

* Android Developer Challenge I: We will accept submissions from January 2 through March 3, 2008
* Android Developer Challenge II: This part will launch after the first handsets built on the platform become available in the second half of 2008

In the Android Developer Challenge I, the 50 most promising entries received by March 3 will each receive a $25,000 award to fund further development. Those selected will then be eligible for even greater recognition via ten $275,000 awards and ten $100,000 awards.

Professional networking : – linkedin

While last time we talked about social networking.

this time we will look at options in professional fields.

when i look at the www the only answer that comes in my mind is

this site has been designed to be able to act as a bridge between workers and employers, prospective employers, overall a network where professional connections are made. which can on one side help a employer find good and resourceful employee’s and on the other ends find allows employees to get to know about their prospective employer.

even if you are not in the business on employer and employee then also getting in touch with professional in any field is very easy in this site.

you can read more about linkedin at the following blogs.

new security approach : sandbox way

Protect your PC by executing a program on Sandboxie

If you execute a dangerous program which can have an virus or visit a site which can install a spy ware into your machine, use Sandboxie!

Programs (including browser) which is executed through Sandboxie reads data from hard disk.
But when programs write something on hard disk (or register), it is written on transient storage of Sandboxie. And the written data will be removed when Sandboxie is terminated.
(i.e. Sandboxie intercepts read operation and directs data to its temporary storage)

See the following figures, you can understand its mechanism.

* existing way *

* Sandbox’s way to protect your PC *

Sandboxie has simple user interface. You can launch any programs as below,

Sandboxie monitors processors which are crated through it. And “[#]” is added after/before the original caption of an application which is executed by Sandboxie. see as below,


It’s free and you can download it here.

I also think that it will be very useful
– when you test your application (e.g. windows application, FireFox extension, etc) for testing.
– when you get rid of all of your trace on a PC of your friend.

the blog originally posted on

My views on this topic besides the above :

From the users point of view , small footprint makes it a good choice.

it install a startup application and then everything could be done write from it.

also right click menu has a new entry for application “RUN sandboxed”

This will bring security to new level. it could easily be implemented on cafe’s and other public place to avoid system hassles.

also its feature to start apps fro start menu opens a new menu containing a list of items available at desktop and all programs menu.

over all its a nice piece of application that should be installed prior to any other application in order to avoid any tension.

How to recover from a hang linux PC

You finally got your Linux environment to crash. Ctrl+Alt+Backspace does nothing, nor do the F-keys. You know you shouldn’t have installed that bad driver, but you did it anyway. So you reach for the power button. Stop. Mashing in the power button to reboot could cause a problem if your hard drive is still being written to, and usually causes more problems than it solves. The Linux kernel includes a secret method of restarting your PC should it ever stop doing its job. 1. Hold down the Alt and SysRq (Print Screen) keys. 2. While holding those down, type the following in order. Nothing will appear to happen until the last letter is pressed: REISUB 3. Watch your computer reboot magically. What the individual keys do in that sequence are not as important as what it does as a whole: stops all programs, unmounts all drives, and reboots. A lot safer than just cutting the power. Here it is again: REISUB. Remember that, as it will save you a lot of time when you are configuring a system and something gets messed up. Need a mnemonic? Try Raising Elephants Is So Utterly Boring. As an aside, don’t try this if you just want to reboot. A normal reboot, if it can be done, should always be used instead of the REISUB keys. R-E-I-S-U-B. Source & Author: Jacob from FOSSwire

how to change root password in debian

This is one of the problem faced by many person’s

“what if i lost the root password”


First thing that comes in mind is “use single user mode” but the answer is NO.
coz debian takes the system security to one more level up and by default ask’s for the root password.

so the BIG QUESTION IS HOW TO proceed further

follow these steps

1) on grub-boot prompt.
press “e” to enter edit mode

2) then press downarrow to reach the line that starts with “kernel ”
press “e” again

3) at the end of this line type in “init=/bin/sh” or “/bin/bash”

4) then press enter to make that change and press “b” to boot

in a few seconds you will be on your “#” prompt

5) only one step left
“mount -o remount rw /”

this step is necessary coz in this case root file system is mounted as read only.

6) finally type “passwd” and you get the screen to change the password

and then type in “init 6” or “reboot”

those who are looking for the technical details, the main work is the init command that we passed as an argument to kernel, it told kernel to specifically run the command specified in parameter instead of working on normal routine.

TRICK = if you have any program you wish to run instead of this then you can do that too using init command only.


use single user mode and change the password.

but that’s a potential pitfall. coz any person can start system in single user mode and get the password changed.

bootsplash a.k.a. Splashy on Debian

Tired of watching screens full of hardware releated info scrolling past during Startup and shutdown.

Welcome to the world of Splash Screen, Screenshots Here

In earlier stage bootsplash screen was configured throught a lot of kernel hacking and using it has a hell lot of hardwork including recompilling of kernel.

But the newest form SPLASHY in a userspace implementation of kernel so that it provides all the necessary features right at userspace.

In debian installing splashy is just a matter of few commands

1) IF you don’t have unstable repo’s in your source list then follow it otherwise skip to step 3

echo "deb unstable main contrib non-free" >> /etc/apt/sources.list
echo "deb-src unstable main contrib non-free" >> /etc/apt/sources.list

2) then apt-get update

3) last apt-get install splashy splashy-themes

After this what you need to is just one thing

open your menu.lst (/boot/grub/menu.lst)
and in the line with kernel value add these words at the end of that line

"vga=791 splash quiet"

Ex : – kernel /boot/vmlinuz ro root=/dev/hda8 ro vga=791 splash quiet

To run Splashy from initramfs you need to create a new initramfs image. An initramfs image is a little system that is

launched during the kernel’s initalization, before the system starts.

During Splashy’s installation Splashy sets everything up so you can get it integrated into initramfs whenever you wish by

just running a single command.

But first you must edit /etc/default/splashy and set ENABLE_INITRAMFS=1 so that Splashy will integrate itself into future initramfs images.

update-initramfs -u -t -k `uname -r`

then reboot and you will have a slashy desktop


All the themes are by defaults installed in /etc/splashy/themes

configuration for splashy is in/etc/splashy/config.xml

and configuration for respective themes is available in /etc/splash/themes/ in XML file format

some of the configuration’s that can be done include changing the colour theme as well as the progress bar size color

direction and image shown.


Once the theme is installed, just run splashy_config -s where name is the name of the theme

To get the complete list of all the splashy themes installed just type in

splashy_config --info

I hope this article will help you all.

Well this question is a long lasting question but a simple answer to this question is that the word LINUX doesn’t represent the whole operating system but it just describes a part of it [though a vital part] that is the kernel sub-system. most of the show that goes on over this kernel is through the GNU softwares and so the name GNU/LINUX in order to give proper credit to them also.

This is my humble request that those who favor me kindly start using the word GNU/LINUX instead of LINUX when talking about the whole operating system but use only and only LINUX when talking about the kernel.
