The story of Adam and chimpanzee

Long ago when the Adam was alone in the garden of Eden,

He started to feel very lonely.
He saw every other species having its own female partner.
He was very much obsessed with his loneliness and decided to search for a perfect match for him.
He realized that chimpanzees are smartest of all species other than humans.
He started searching for the best one among all female chimpanzee to start sharing his living. With his best efforts he finally found one.

When he was about to make a decision on “the” chimpanzee, a thought dangled in his mind.
“Though I searched all the way and found the best and smartest chimpanzee, still its a chimpanzee not a human.”

In the last moment he gave up that thought of living with chimpanzee.
“God” was observing all this, and when Adam fell asleep he took one of side bones and created Eve for him.

The next day he realized, the soul mates are made but not chosen.
Adam and Eve became the best soul mates for ever.

(From old testament)

PS: May be we should realize too.

Buying a new windows laptop? Then this is worth a reading.

If you are going to buy a new windows laptop, then you might be interested in reading this.

In this post I will just touch the normal and common problems we face with windows laptops and the remedies I followed.

Here we go.

A. Once your laptop’s initial config is done(setting up the users for the first time use), DO NOT connect to internet or DO NOT install any software.

B. Restart your lappy, and set the BIOS admin password(May be you will have to press DEL button while your lappy boots). This will be helpful for protection from H/W tampering and misuse.

C. Always try to use the Genuine Windows. And keep it regularly updated.

D. Try to insure your laptop. Security from theft.

E. Some of the games are still supporting Windows XP. So you might wanna download this in case you are gaming fan.
http://www.microsoft.com/windows/virtual-pc/download.aspx

F. Partitioning the drives. ***This is the most common issue***
All windows lappys mostly come with a single MAJOR partition which will be used for both Windows and personal usage.

But its always recommended to have a separate partition for your personal stuff. Which will give you the freedom of completely formatting the windows partition if required.

So here is what we can do to create a new partition for our personal usage keeping the windows intact.

Right Click on My Computer > Properties > System Protection > Protection Settings (Click on Windows partition and click configure button)

Then take below two steps
1. Turn off system protection
2. Disk space usage > Max usage > Keep it around 80GB
3. Apply – OK

4. Run > diskmgmt.msc
5. Right click on windows partition > Shrink volume
6. Enter the new partition size you want to create in the amount of space to shrink. (Remaining space will be kept for windows partition, so be careful while choosing this value. I always recommend to have around 100+GB for Windows 7. So you might need to keep the “Total size after shrink” to equal or 112640MB ~110GB)
7. Shrink.
8. Now check your disk partition table. It should be having the freespace you want.
9. You can play around with that like what ever way you like.

10. LAST but important*********
Revert the first 3 steps we did to original. Keep the max disk space usage to 80GB. That should be fine.

Here is my new partition table layout.

Here we end with having our partition table and genuine windows as well as Linux.

Good luck.
See you again.

Thanks for your time. Comments are welcome.

Saga of my Master’s trial

Its been my dream from a long time, perhaps right from the college days. But never thought that I would be writing a post on my blog like this.

It all started when my favorite professor said that his son studied in Harvard University. I wanted to study in IITs, but later realized that it a little high target for me. At least I thought of giving a try for this as every crackfot will be going for master’s and why cant I. And the idea got planted. Getting selected in campus placements in the college has created a boundary of responsibilities and pushed me to go with job. And I did. After two years, with the help of my best friend I dug the masters idea again from its cemetery and started to bring it back to life. Started to plan for that in parallel to my job in reputed IT MNC.

April 2009: GRE Practice. Toefl practice. Required a computer and I bought one and soon lost it with in one month.
September 2009: GRE needs at least 1100 and Toefl needs at least 93 to call them as good scores. I screwed them both (1030,91).
December 2009: Applied for two universities and one said nothing (not even a rejection) and the other said they dint even get my application (what a turn). I sent the application once again that dragged for six months and I got no update from them.
April 2010: Reached some XYZ people for get the update on my application and deferred my admission to next semester to due delay in admit.
August 2010: Somehow got admit for that university and took around one and half a month to get the I20.
October, 2010: US Consulate, Chennai. Visa rejected under 214-B, due to my tensed face and dumb answers for a simple question like “Why MS?”
October, 2010 : US Consulate, Hyderabad
Felt much confident and attended the interview with the same confidence. But again screwed up at some question on finances, and it resulted into one more 214-B.
November 2011: Thoughts of MS were almost moved into trash.
But thought to recollect after talking to my best buddy.

Still I let my H1B to go further which is being sponsored by my company.

December, 2011: My H1B petition was filed at USCIS
February, 2011:
My H1B was approved by USCIS
March, 2011: H1B documents were received.
April, 2011: US Consulate, Chennai. Barely 2 questions, and visa was stamped.
May, 2011: Tickets booked for travel on May 13th.

Now tell me do you believe in fate.
Till now I wasn’t, but now I don’t have another choice.
I was more destined for a job than to study, may be.

First flying experience .. thanks to Vw350en

I never thought I would get such a chance .. Got a call from Vw350en, and in no time they asked me to come over to Hyderabad.

In two days air tickets jumped into my mail box, I slowly started getting excited.

Up journey: MAA to HYD at 6:30 AM (Indian Airlines)
Down jouney: HYD to MAA at 6:55 PM (Jet Air)

Great!

Called one of my friend whose working as AME in MAA airport and asked him for guidelines. He suggested me to before at least 1hr saying its a peak time for domestic. Huh .. peak time I thought .. at morning 6:30 .. lets see ..

Went down to MAA at 4:30 AM itself, then I understood what he meant by peak time. Thousands of people are standing in queues of each airlines counters. Out of 4 Air India counters only 2 were open and there were 200 people standing in Q.

Waited patiently and took my boarding pass(took window seat:)) after 1 hour and 30 min more of security formalities.  Finally boarded the plane at 6:15 AM, it started at 6:30 and finally I started with my first flying.

Plane took 5 min running over the land for reaching assigned take off point. Upon reaching it, it started to accelerate and finally into air. I felt much that it was moving with great speed when on ground, but in the air it felt very smooth and  slow. However the images down on the earth started to become miniatures. Its like zooming out from the google maps using satellite mode 😀

Soon the clouds became visible right beside me,  in 2 more min there are no google maps out side only great white fur spread till the horizon.  See snaps I took. It was nice. May be this is one of the reason which will motivate skydivers:)

Spent time in flight of 55 min … breakfast, seeing the clouds, watching some movie on screen etc.

Soon we entered Hyd air, and it landed slowly landed with a thrust. Then I understood how much fast we were flying. (It was not easy to figure out when it was in air but can be on ground). Got down the plane, thanks for NO formal security checks for domestic arrivals (which might have killed some more time) .

In the outside lobby, I saw the driver holding my name card. Approached him and started towards my destination place which took more time than flying from MAA to HYD 😀

Using a GSM Cellphone as a GPRS Modem

hi all,

we know that .. in todays our pals are facing much problem in connecting to internet in Linux using modems.The following will let you learn how to connect to internet using your GSM mobile and the GPRS connectivity.

Before starting i will tell you my system configuration

— Intel 2.66 AM64T on Intel 915 GVW, 512MB RAM, 160 GB HDD

— Ubuntu Edgy 6.10 + Gnome

— Sony Ericsson K320i

So here we goes….

Step 1:

First connect your mobile to your system through the USB connectivity.

And chose the option “phone mode” (If its available)

Step 2:

Now its time to configure your mobile, Open a terminal and login into root account there.

$ sudo su

# wvdialconf

ttyS0<*1>: ATQ0 V1 E1 — failed with 2400 baud, next try: 9600 baud
ttyS0<*1>: ATQ0 V1 E1 — failed with 9600 baud, next try: 115200 baud
ttyS0<*1>: ATQ0 V1 E1 — and failed too at 115200, giving up.
Modem Port Scan<*1>: S1 S2 S3
WvModem<*1>: Cannot get information for serial port.
ttyACM0<*1>: ATQ0 V1 E1 — OK
ttyACM0<*1>: ATQ0 V1 E1 Z — OK
ttyACM0<*1>: ATQ0 V1 E1 S0=0 — OK
ttyACM0<*1>: ATQ0 V1 E1 S0=0 &C1 — OK
ttyACM0<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 — OK
ttyACM0<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 — OK
ttyACM0<*1>: Modem Identifier: ATI — Sony Ericsson K320
ttyACM0<*1>: Speed 4800: AT — OK
ttyACM0<*1>: Speed 9600: AT — OK
ttyACM0<*1>: Speed 19200: AT — OK
ttyACM0<*1>: Speed 38400: AT — OK
ttyACM0<*1>: Speed 57600: AT — OK
ttyACM0<*1>: Speed 115200: AT — OK
ttyACM0<*1>: Speed 230400: AT — OK
ttyACM0<*1>: Speed 460800: AT — OK
ttyACM0<*1>: Max speed is 460800; that should be safe.
ttyACM0<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 — OK
WvModem<*1>: Cannot get information for serial port.
ttyACM1<*1>: ATQ0 V1 E1 — OK
ttyACM1<*1>: ATQ0 V1 E1 Z — OK
ttyACM1<*1>: ATQ0 V1 E1 S0=0 — OK
ttyACM1<*1>: ATQ0 V1 E1 S0=0 &C1 — OK
ttyACM1<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 — OK
ttyACM1<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 — OK
ttyACM1<*1>: Modem Identifier: ATI — Sony Ericsson K320
ttyACM1<*1>: Speed 4800: AT — OK
ttyACM1<*1>: Speed 9600: AT — OK
ttyACM1<*1>: Speed 19200: AT — OK
ttyACM1<*1>: Speed 38400: AT — OK
ttyACM1<*1>: Speed 57600: AT — OK
ttyACM1<*1>: Speed 115200: AT — OK
ttyACM1<*1>: Speed 230400: AT — OK
ttyACM1<*1>: Speed 460800: AT — OK
ttyACM1<*1>: Max speed is 460800; that should be safe.
ttyACM1<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 — OK
ttyACM0<Info>: Speed 460800; init “ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0”
ttyACM1<Info>: Speed 460800; init “ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0”

Step 3:

We will be getting the similar output as above…. when we wvdialconf

So after we need to identify at which port (or the device) the modem is identified. That can be found out by identifying the line

“ttyACM1<*1>: Modem Identifier: ATI — Sony Ericsson K320”

and now open the file /etc/wvdial.conf

# gedit /etc/wvdia.conf

It will be looking like

[Dialer Defaults]
Modem = /dev/ttyACM0
Baud = 460800
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
ISDN = 0
Modem Type = USB Modem
; Phone = <Target Phone Number>
; Username = <Your Login Name>
; Password = <Your Password>
New PPPD = yes

So in the above code we need to make some changes as per your mobile. Since the mobile is pointing to modem = /dev/ttyACM0, where as the wvdialconf returned /dev/ttyACM1 as the modem as shown above. So change the line “Modem = /dev/ttyACM0” in the /etc/wvdial.conf to  “Modem = /dev/ttyACM1.

And we cant just keep the other fields empty, so just dial your service customer care center and find out the dial up number for your GPRS-Internet connection. And ask for any username and password (if they exists for your GPRS service). Fill that fields in the /etc/wvdial.conf accordingly.

If you are not having any username and passwd … wvdial will not allow you leave those fields empty, so just fill them with your own data like

Username = bob

Password = crank

And be sure to keep the following line, if you are not having any username and password.

Stupid Mode = 1

Once you are sure that you, configured your wvdial fine. You can dial-up your GSM modem by following.

wvdial

and you will be given your IP address and the server IP address displayed. You can hang the connection by just pressing the CTRL+C.

Hope you got it well.

Later.
