Introduction

I was born at Adoni, Kurnool district, in Andhra pradesh 1985. My Father B. Narayana garu, and mother B. Lakshmi Devi garu. My father was good hardworker. He does not want to waste time unnecessarily. He cares very much about me & loving, caring & giving precautions. He is very strict in discipline towards us. My mom is very friendlier to me. She knoweth whatever things I have need of before I am asking her. My belief "Mother is the God's best gift" to everyone. I have one elder brother Narsimha Raju & sister Krishna veni. We were making funny things & quarreling always in childhood.
Adoni is a small town surrounding with small villages & with full of greenary scenarios. It is also called as "Second Mumbai" because this place is famous for cloth business.

My School days
From my early age My parents sent me to School named S.P.N.N.M convent. I began school career in 1988. I was simply sleeping in the classroom during class hours upto 3rd class. But my father was daily asking abt., the subjects. I, my brother, sister had to tell all the question & answers whatever taught in the class in every evening. Otherwise no supper in nights. So I was updating syllabus.
My father was waking up us 5:00 am daily and We had to revise the subjects from 5:00- 6:00 am. Like that daily one subject English on Monday, Telugu on Tuesday,... Hindi on saturday. He was giving holiday on every sunday.
So I was always stood Ist or IInd Rank in school. My teachers were also appreciating me. Thereby I got good impression among teachers. I got prizes for regular student because there was attendace report every year. I was getting 98-99% attendance every year. I got best student prize in my Vth class. There was my best teacher Janaki Madam. She was always knowing the problems of students, guiding & giving directions for my studies.
After my Vth class, I joined High school T.G.L.V. Govt., High School. There I faced some competition in studies. But I was maintaining my grade in top 3. i got 98/100 in Science subject in my VII class. For that I got prize & I became popular in high School. But my father want me to always as Ist Rank. He wants the best always. Anyway finally I managed my grade level.
I fond of music very much. One of my friend Suresh invited me to church ZION. I liked the piano, violin music in Sunday schools in the church. They taught so many stories & morals. I liked the simplicity & holiness in church.

College Life
M.P.C
In my Intermediate College Viswanarayana jr. College, again I faced lot of competition with different tallented students. I got 87% in Ist yr. Some other students got 92,94 %ages. I felt very unhappy. I realized the drawbacks in me after introspection in my life. They are good at English & communication skills. So they are scoring good marks in the languages which leads to be as top rankers in the class. Then I applied for improvement and I got 3rd Rank with 94%. I tried for Ist rank but I didn't get due to lack of knowledge in the languages. The first two rankers are girls. My class girls are very tallented. I was not talkative. I was afraiding of talking to girls. Anyway finally I got total 92.8% & stood top 4 in my town. For that I got BC scholarship & the top 10 rankers were published in Enadu news paper. That was my first achievement in my life.

Graduation
B.Sc M.P.IC, A.P.R.D.C, Kurnool.
After my Intermediate I have interested to do B.Tech CSE. I got good rank in EAMCET but i didn't join due to financial problems. I didn't know what should be next step life. My father was already fed up with financial problem. He didn't want me to study. he said me to do some job/work. I didn't know what I have to do. But I am very much interested to continue higher studies. I prayed God simply by telling my worries and giving concern to God. I got answer from God i.e., My High School Mathematics Teacher named Adivappa Sir helped & guided me to apply A.P.R.D.C for B.Sc.
I didn't have money to get applicaton. It costs 300/-. My neighbour had given amt. Actually he had taken rent in upstairs of my house. Finally I got State Rank 21 in A.P.R.D.C. I joined B.Sc MPIC in Kurnool in 2003.
In my first yr, full of ragging(singing, jumping like a frog, measuring with match sticks, salute) in the college. That was my first experience of ragging. I am afraiding of it. Most of the times I was escaping from ragging and spending time in library. Anyway after freshers party seniors & Juniors had good relationship like brothers. Seniors helped & guided me a lot in studies. There I knew how the life is. Because lack of facilities in the govt., college. Govt., was giving 12/- per day to each student for accommodation & food. Anyway I maintained good percentage 83% as well as enjoyed a lot like in Room day, Block day, Hostel Day, College Day festivals, cultural activities, competitions etc., This was the happiest life that I spent in my B.Sc.

Post graduation
MCA, S.V. University, Tirupati.
My specialization in B.Sc was Industrial Chemistry. I started preparation for M.Sc IC in II yr. But I changed my decission to do M.Sc physics in final yr., due to some of my teachers guidance. Finally I have written M.Sc physics entrance test & I also ICET (for MCA) bcz., of interest in CS. I got 46th rank in Sri Krishna devaray University, Anantapur. I decided to join M.Sc physics (free seat). But my Intermediate College Mathematics Lecturer named "Padmaja Madam" said me to do MCA which have lot of job opportunities comparing to MSc Physics. I am also interested in CS. But there were more financial problems in my family. Its a wild goose chase to do MCA for me bcz., I didn't have amt., or no facility of loan bcz., no one given surity even my father also. I had interest in higher studies still after my Degree. Acutally all this problem is not due to financial problem but due to improper planning to opt M.Sc/MCA. If I had a proper plan then I would have got good Campus (free) seat. Then I prayed God simply by putting every concern on him. Finally My madam & Sir helped me for Education loan. They took lot of concern on me to do MCA.
My MCA college was the worst college. I never saw such a college in my life. Even if intelligent student goes he will become dull. I wanted to left the college. But due to my Madam guidance I continued my MCA there. There was no classes, no good faculty, no good lab, etc., and also I don't know abt., computers. I felt the first program in C as Urdu language. I didn't understand anything like #include, main, etc., why all these? What's the purpose. My friends Mahukar, Chandu, Satish guided me to study Let us C-Yashwant Kanethkar. I got 66% in my MCA I sem. Its a very less percentate in my career. Having some experience I started studying on my own & going to coaching for C++, Java, .NET. in II, III, IV sems & in holidays without going to home. And also I decided to write GATE having a well plan in my MCA I yr. I attempted GATE in II yr. for practice. But I didn't get the rank first time. I prepared well & thoroughly. I got good AIR 820 with 95.4 %ile. Thus I came to know the maxim" A well thought plan has a high chance of success". I also got good percentage 74% in MCA & stood College Ist.

M.Tech CSE, NIT Calicut.
Even though I got good Rank my fate was not changed. Again financial problem. I had to pay 22,000/- admission fee to join M.Tech. My parents & sister have hope abt., my career towards job after my MCA. But still I have very much interest to continue higher studies in great IITs or NITs. I convinced them because doing M.Tech is similar to job. So I met P.S. Moorthy sir, English Retd., Lecturer, the founder of Swamy Vivekananda Samstha in my town. They helped me 9000/- and remaining amt., by my madam and some well wishers.
Some of my relatives commenting me that I am studying still without doing job. I didn't care any comments. My belief is "If you have interest you can do". That is my first preference in doing anything.
After arranging the amount, I came to NIT Calicut counselling with my friend Mallikarjun Reddy (Jubilee mate). He got 95.8 %le in GATE. But he didn't get call letter here unfortunately because he forgot to include study certificate (for his M.C.A VI semster) while applying. We tried to convince admin people so much but no use. Actually my friend is also from poor background family. Even though I got seat here, I felt very sad abt., my friend's fate because he is the best friend. Anyway he got seat in NIT Rourkela.
In my first semester, I thought that its easy very to study because all the syllabus is same as in MCA. But the way of teaching, Exams, Technical things are very high level here. After realizing, I changed my way of studying according to this pattern. I am very good at programming skills but not in Engineering. I believed that implementation is more important than other things. But after meeting with my HOD, I came to know that Engineering is more important than implementation. Anybody can do implementation if design and engineering is perfect. The programmer is only average human being.
I got some good friends, enjoying in programming, good climate, visiting places, facing high competition from keralians in studies. I have never seen such a cool & peaceful place like kerala in my life. This time my grade is 7th place because here they have good basics in their B.Tech & some experienced QIP students. Anyway I am very happy to be within Top 10 positions. I got 8. 16 CGPA in I year.

Java

java is pure object oriented programming language, robust and secure language.

M.Tech CSE II year
Project
: Cloud Computing

CLOUD computing is an emerging computing paradigm which combines the technologies like grid computing utility computing, virtualization and clustering to provide a set of services to the cloud customer. Cloud is a higher level abstraction, where the underlying hardware and software details are hidden from the user. The end user can avail the various services provided by the cloud to build his/her applications.
The services that can be provided from the cloud includes Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). Software as a Service rent applications functionality from the service provider so that the client can avoid purchasing, installing and running the software necessary for the application. Salesfroce.com is one such company which is providing the service of this type. In Platform as a Service, the idea is to provide the necessary platform for developing and executing the client application. Google and Microsoft are two major players in providing PaaS. In PaaS, the services provided include database management, security, Work flow management, application serving. The computational power and storage space required for the application are also offered as a service from the cloud which is known as Infrastructure as a Service.

Problem Statement

To achieve semantic interoperability between web applications (such as JSP, PHP) using XML. Development of algorithms for prototype implementation to test the methodology specifically by converting JSP to PHP and PHP to JSP using XML as an intermediate representation.

Programming Skills
Every body knows C/C++ basically. I have very much fond of Java.




Linux Basics

1. Creating Linux Partitions

After booting the installation media, run fdisk by typing

fdisk <drive>

where drive is the Linux device name of the drive you plan to add partitions. For instance, if you want to run fdisk on the first SCSI disk in your system, use the command fdisk /dev/sda. /dev/hda (the first IDE drive) is the default if you don't specify one.

If you are creating Linux partitions on more than one drive, run fdisk once for each drive.

veeresh@veeresh-desktop:~$ sudo fdisk /dev/hda

Command (m for help):

Here fdisk is waiting for a command; you can type m to get a list of options.

Command (m for help): m
Command action
a toggle a bootable flag
d delete a partition
l list known partition types
m print this menu
n add a new partition
p print the partition table
q quit without saving changes
t change a partition's system id
u change display/entry units
v verify the partition table
w write table to disk and exit
x extra functionality (experts only)

Command (m for help):p

Disk /dev/hda: 16 heads, 38 sectors, 683 cylinders
Units = cylinders of 608 * 512 bytes

   Device Boot  Begin   Start     End  Blocks   Id  System
/dev/hda1 * 1 1 203 61693 6 DOS 16-bit >=32M
Command (m for help):
In this example, we have a single MS-DOS partition on /dev/hda1, which is 61693 blocks (about 60 megs).This partition starts at cylinder number 1, and ends on cylinder 203. We have a total of 683 cylinders in this disk; so there are 480 cylinders left to create Linux partitions on.

To create a new partition, use the n command. In this example, we'll create two primary partitions (/dev/hda2 and /dev/hda3) for Linux.

Command (m for help): n
Command action
e extended
p primary partition (1-4)
p

Here, fdisk is asking the type of the partition to create: extended or primary. In our example, we're creating only primary partitions, so we choose p.

Partition number (1-4):

fdisk will then ask for the number of the partition to create; since partition 1 is already used, our first Linux partition will be number 2.

Partition number (1-4): 2
First cylinder (204-683):

Now enter the starting cylinder number of the partition. Since cylinders 204 through 683 are unused, we'll use the first available one (numbered 204). There's no reason to leave empty space between partitions.

First cylinder (204-683): 204
Last cylinder or +size or +sizeM or +sizeK (204-683):

fdisk is asking for the size of the partition to create. We can either specify an ending cylinder number, or a size in bytes, kilobytes, or megabytes. Since we want our partition to be 80 megs in size, we specify +80M. When specifying a partition size in this way, fdisk will round the actual partition size to the nearest number of cylinders.

Last cylinder or +size or +sizeM or +sizeK (204-683): +80M

Warning: Linux cannot currently use 33090 sectors of this partition

If you see a warning message such as this, it can be ignored. fdisk prints the warning because it's an older program, and dates before the time that Linux partitions were allowed to be larger than 64 megabytes.

Now we're ready to create our second Linux partition. For sake of demonstration, we'll create it with a size of 10 megabytes.

Command (m for help): n
Command action
e extended
p primary partition (1-4)
p
Partition number (1-4): 3
First cylinder (474-683): 474
Last cylinder or +size or +sizeM or +sizeK (474-683): +10M

At last, we'll display the partition table. Again, write down all of this information---especially the block sizes of your new partitions. You'll need to know the sizes of the partitions when creating filesystems, later. Also, verify that none of your partitions overlap.

Command (m for help): p

Disk /dev/hda: 16 heads, 38 sectors, 683 cylinders
Units = cylinders of 608 * 512 bytes

   Device Boot  Begin   Start     End  Blocks   Id  System
/dev/hda1 * 1 1 203 61693 6 DOS 16-bit >=32M
/dev/hda2 204 204 473 82080 81 Linux/MINIX


/dev/hda3 474 474 507 10336 81 Linux/MINIX

As you can see, /dev/hda2 is now a partition of size 82080 blocks(which corresponds to about 80 megabytes), and /dev/hda3 is 10336 blocks (about 10 megs).

Finally, we use the w command to write the changes to disk and exit fdisk.

Command (m for help): w

Thus Linux partitions are created successfully.


2. How to setup Internet connection in linux environment?
All of us know about setting ipaddress details in Network connections icon which is on system tray. To setup permanently follow the steps:
open the terminal:
veeresh@veeresh-desktop:~$ sudo su
[sudo] password for veeresh: *****
veeresh@veeresh-desktop:~$ gedit /etc/network/interfaces
auto lo
iface lo inet loopback
iface eth0 inet static
address 192.168.3.182
netmask 255.255.255.0
gateway 192.168.3.1
auto eth0
veeresh@veeresh-desktop:~$ gedit /etc/resolv.conf
search localdomain
nameserver 192.168.254.2
nameserver 192.168.254.3
veeresh@veeresh-desktop:~$ /etc/init.d/networking restart
Note: In fedora use setup command on the terminal to configure the ipaddress.

3. Tool for CD/DVD R/W k3b (like Neuro 7 in Windows)
K3b is a CD and DVD writing ('burning') application.

Key Features
  • KDE-friendly application
  • Write data disks
  • Write audio disks
  • Write 'images' to disk (e.g. Linux distributions)
  • Copy disks
Installation
open the terminal:
veeresh@veeresh-desktop:~$ sudo apt-get install k3b
After successful installation
veeresh@veeresh-desktop:~$ k3b
