hi now i m telling u my first novel which i read in b.tech 4th year. that novel is related to the student life.i heard the story line before buy it so i was too excited to read it. i completed it in 2 days. that novel name is 5 point someone.
there were three guys who always secured 5 point in iit. that story was of three friend they all iitans from delhi. and they are all good in studies but one of them was care less and they all found of having VODKA on the roof at the dark corner.
2nd one had gone for a morning walk and found a girl which is daughter of his faculty. so he lost to study in fact caught by his faculty at his home. where he was wearing his teachers shirt and his girlfriend having his t shirt. that was too interesting part of the novel. a guy ryan was fond of having a vodka and just because of that he was thrown out of the class. they all stupid guys tried to steal the examination paper from the office.
actually this novel is related to every student who is taking technical education from any institute. he can understand what that novel is trying to reveal. when i was reading book i was lost in that book and each and every character. i felt myself as i was Reading my story or my friend that is too close to me. and i know everything about him so that i can analyze his feeling and his situation which he is facing.
that novel was just for fun but really i had lost in that story. i was too excited regarding This writer (Chetan Bhagat)who was an iitian, i took his another book a night at call centre. even at that time i did not completed my first novel. the another one is also good story of some people working at call centre in delhi and haryana border.
chetan Bagat is really a good writer who writes i think only for bachelor.......
every technical student should read this he will feel that this story is related to me...................

my first novel which influenced me alot
Here I am going to tell you about that novel (which i read in b.tech 2nd year and is my first novel)or you can say a story which influences me a lot. for my b.tech result my younger brother gifted me this novel 'Alchemist by Paul Coelho'.I am thinking whats this novel is all about, there was a quotation 'A magical tale to follow your dream'.
First I thought that this is something thrilling novel but as soon as I started reading that I realized that I am wrong and its totally different from what I am thinking about that. that is something related to you, your strength.
I took 3 days to finish that novel as I turning its pages I really feeling that some how its connected to me and to everyone and thinking about the writer how he pick the nerve of the reader.
So as the hero Santiago only believe on his will power, not on fate and there were many incident happened with him in that he showed that how one's will is superior than the one's fate.
Santiago come to learn by the incidents which was happening in his life that there was only one way to be happy forever that was to listen to your heart and whatever had to be left for that leave it. don't bother for the past and don't worry which is being happened always worry for present. Only follow your heart than only you can happy, than only you can get true love and the soul enlightenment.
So there were many theory developed in my life after reading this book, like every one has its one's field for learning and only that person can survive in that field.Always follow your heart ,each and every time it says something when you are taking some decision and it knows how one can be happy in his life. as every story teach you something that you can test in your daily life. as well i thought this story is something which i have done before in my life.
Alchemist is all about to follow your dreams and we have to never compromise our dreams with any thing. i prefer to recommend this to every one. everyone who likes books should read it........

1st module of ncst
2 months and 10 days back, i was here for very first time. and listening to RAMAN sir's word that "this beautiful place going to be hell for you." but belive me my friend being here i am happy because i am more confident and technically more sound. which we forgave in our graduation that things are starting here.
some people told me that if you can survive here then you will not feel any dificulty in any organization. and i am happy to be here. in our starting days here we are putted in front of unix to code well that is not a big deal but i seems to be more technical onwards. our some classes on unix introduction. then we are putted on java classes that is held by Balaji sir. he taught us all the concept of java infact oops concept. another subject which is parallel to java is DSAL that is data structure. i think there is nothing left to study. he taught everything and provide us a solution for implementation. i did not use such code before. and for testing we are evaluated with MGPAs that is pathetic. in the sense, last night of mgpa is worst but we enjoy that experience as i did ever heard such online evaluation in ant institute.
well to clear the module we are supposed to clear 4 mgpa out of 10 and i have over through it. i can say anthing for raman sir is that he is as fair as Y in parikshak with his knowlege. he transmit only that which he is supposed to.
another subject was TCOM that subject is only for evaluation as even there is nothing to teach but there is almost every class we had a evaluation. and had to listen hi dear you should improve this and do this, dont do like that.
there is an incident related to TCOM class. we are 7 peaple in a group. and one of us was having a bath and told us to wait for him. Swani mam told "5 min is early on time" and we were 10 min late. that day we have thrown out from the class and we then enjoyed all tha day at oliveshop. at the next day we were again late and mam recognized us and announced evaluation is not for us. but she forgot thank God...........
today onwards there is only 3 days left to get over this module. there is only one paper left and one mgpt is to go. then we all going to home after 3 and half month i am too excited to go home as i am first time out side from home to long................

hi yaar now i am going to share you something that made me vary pain full.....
when i came in ncst every senior told me that prepare to stay here in any condition. and some said vaibhav you are going to stay here anyhow......... actually i am not supposed to clear the 4 mgpa but only stay here. they said if you be here till the end you will be very confident and able to face any condition in corporate.
i got cleared my first mgpa.... i felt good. then i have to face failure in my next consecutive mgpa. at that time i was on the fire with more knowledge and force. then i have cleared 4th and 5th mgpa. then another was on dsal and i was afraid of attempting that mgpa and received the same result i blocked with the problem. then next mgpa was on java i was confident to attempt that but there was a problem related to the toughness of the problem which we are supposed to crack.
just before last night Govind sir came to us and tell us a problem to compare the cube. i was few of them who gone through that problem. so i was thinking that i can do that mgpa and will cross the deadline.......................
and them the time was with us and we were in the hall to think over the problem... i created that logic with in the 15 minutes and did not pay my attention an the dry run and i have gone for a failure.......
i was really frusted after the exam got over...... really according to me i was supposed to clear that mgpa. and i thought if can not crack that mgpa them may be i can not do better in the next.........
so i did not make much efforts for preparation. i have cleared 8th and 9th consecutively............. and i am across the deadline.... really that moment my friend astha told me the importance of dry run. that is why i am able to crack next two mgpa.............
really i remember a statement of last year student that you should stay here and you will be very confident to face any condition and you will fine some friends that will go with you for a long......................

God is with me on the earth (Lets meet)
Every one say that mother is Divine. but i can tell how is she Divine for me. Mother cares for you every time. she tells you what to do what shouldn't. She gives you food without taking care of herself.
mother beats you when she is angry on your stupidity and then cry why she beat you.
after the death of my father we relocated from my birth place. at that time i was in 8th class. whenever me and my brother went to school, my mother was alone in the house and thought about the past. She then thought about study again. and started teaching. she began with a school K.L.Baal upvan that is small school situated in bijnor.
after one month my mom came to home, we were there and we looked that she is crying and crying. when we asked her she cried again. she put an envelop in front of us an cried allot.
just because of one month back she has given a salary of 1500 to our helper and now she is getting salary of 800 bugs only.
that was not a matter of money but that was a matter of engaging her time.
then she started study. she did B.A. again in English Literature then N.T.T then M.A. in sanskrit and at last B.Ed now she is preparing for P.H.D. the main centre of attraction is that she secured more than 60% in each examination. she woke up in the morning at 5 then prepared breakfast for us and then went to college. she came back by 2:30 and again prepare for lunch for us.
she had to manage all about her teaching and her two naughty children and her study. that was too typical to study in the age of 35 and prefer outstanding. really that is too typical to study after 13 years of marriage.
well she made very typical and strong decision in her life. she went both of her sons as me and my brother for B.Tech. that was too manageable for money but she had done it well. she is ideal for me.
............................
i ever try to make me like her but i realize that one can not be like her. she is the only of her kind. one cannot be like her. no one can do such laborious. i thing i forgot to tell you about.
why i m telling you she took a strong and tough decision to send us for study just not because of money. NO NO the reason is that for our study my brother was in ROORKEE and i was in Ghaziabad.
so she had too live 4 years alone in the house. and she is alone now. but she is getting the result of her sacrifices. her younger son has got placed in Reliance info Solution as a s/w trainee.
she is ....................

something special for me
this time i had to go to attend technical fest at IIT roorkee. i was informed about the event "Static web pages" and "Dynamic we pages". these were the two event from one of which we had to register with a group name and member. we were given nearly 50 hours to decide and represent that web pages. we had decided to proceed with static pages. In that time we had to collect all the information about the topic.
oops i forgot to tell you about the topic. the title was "Yello Pages For Roorkee". means all related information of roorkee. so we had to do extreme work for gathering information. we have covered all the department at roorkee. Hydro, IIT roorkee, cantt.
we had to rush at amar ujaala office to find out old copies in which some article published about dr. Kalam when he visited over there. then we took picture of the very first train engine which was run very first time in India. that was used to transfer the goods for 3 km. we collected some picture related to that engine and hydro department.
we had to cover all the list of in coming and out going busses in roorkee. and the transporter dealing from roorkee. the we went to roorkee railway station took picture of railway station and covered all train passed from there and timing as well.
these all matter we had collected in 36 hours and by the side we were managing that information with that pages. after collecting this information we were in the situation to die but again we started working with our pages. finally, just before one hours we had completed our pages and reached at the venue.
we just presented our pages to the director of IIT roorkee and an anoher chief guest from Roorkee Cantt. then we came back to room to chill out we were not thinking about the result. at 2:30 pm, we got a call from our friend he told "what have you done in iit there is a notice related to you three" we really scared about that. then he told that "dear you have secured first rank there is a notice related to that". we just ran away from without locking the room. IIT was two and half km far from there and we reached there with in 5 min.
we were chilling out there and that was an honour to receive a gift from director of IIT.
i really can not forget that moment. when i received a certificate and shaked hand with him.

trip to KHARGPUR
This was the official trip from college when we were going to attend the technical fest in IIT KHARAGPUR. i was the only person from my college rest are from other college. the group was of 47 students from different college.
After my third semester examination got over, we started our journey towards Khargpur. we all were in a single coach in the same train. you can easily feel what was there for 3 days. At 3AM we reached there and IITians were waiting for our arrival. that really sounds good. they were so caring and sweet as well.
the arrangement was superb there. we did not feel any problem over there except campus was too big and we had to walk a long for event to event. In fact, there were over 10000 students to participate there. compition was too tough. but we enjoyed that a lot.
there was one event NIRMAAN in which we had to make a building construction to protect from Tsunami. eventually we got entered in the third round and secure 7th rank oin this event.
there were some cultural event too where some shows were like PC Sarkaar's shows.
that was amazing. there was some technical event related to programming in c++. i got selected for second round and thrown out immediately. that was to typical to understand as far as concern to me.
there were some work shop announced specially for ethical hacking by Ankit Fadia. that work shop was superb. he told me a lot about XP and hacking related to ATM machine.... but really i am telling you "sab sir ke upar se nikal gaya".
hi dear , i forgot to tell you about food over there. there was a variety of food. specially there were different restaurant for different taste(region wise). that was awesome there.
the student in IIT khargpur was too caring and supportive.
really we enjoyed that trip but at that time of returning we were too tired. even we were not caring about our luggage that where is it lying.
that was a new experience as i was too far from my native place for the first time and really i did not feel ant problem with it. This trip gives me an unforgettable experience.

To Be Continued...
Lets know about .NET
The MicroSoft.net framework is a new computing plateform that simplifies Application Development for a heighly Distributed enviornment even Internet.
The .net framework is designed to fulfill the following object.
*To provide a consistent object-oriented programming environment.
*To provide a code-execution environment that:
-minimum software deployment and versonning conflict
-gaurantees safe code execution
-Elimination the performance problem of scripted or interpreted environment
-makes developer experience conflict across widely varying types of application.
*To build all communication on industrystandards, to ensure that code based on the .net framework can integrate with any other code.
The .net framework has two main components:
#The CLR(Common Language Run-Time)
#The .NET Framework LIbrary
The CLR is the foundation of the .net framework. The code that targets the run time is known as managed code. While the code that does not target the run-time s known as unmanaged code.
The .net framework can be used to develop the following type of application and services:
-Console Application.
-Windows GUI application (windows forms)
-ASP .NET Application
-XML Web Services
-Windows Services
-Services Components
MS.NET provide the following Services:
*Run-time environment, the .net framework
*Progarmming model for constructing HTML pages, named ASP.NET
*XML web services- A new way for internet services to expose function to any client
*windows forms- Anew way of writing Rich Client Application Using ther .NET framework
ADO.NET, which provide good support for database access within the .NET framework.
*Support for handling XMLDocuments and Streams.
*Standardized mechanism for signaling asyncronous events.
*Support for writing Multithreaded code
*Enhanced connection from one .NET system to another .NET system
*Support for run time discovery and invocation of an objects method and properties
THE Common Language Runtime
The CLR is software Engine that load and manages the execution of code on the .NET plateform.
The architecture of .NET realized that all procedural language required certain base functionality. for example, Memory Management.
So, instead of each language shipping with its own runtime, it would be better if all language could use a common runtime.
The CLR consists of Various Components that provide the runtime environment and services for application.
*Class loader, load classes into the runtime.
*MSIL to Native code Complier, convert MSIL code into Native code.
*code manager, Manages code during execution.
*Garbage collector, performs automatic memory management
*Security engine, enforces strict type cheacking.
*Thread support, provide multithreading support to application.
*Exception manager, provides a mechanism to catch and handle run-time exceptions.
*Debug Engine, allows to debug applications.
*COM Marshaler, allows .NET application to exchange data with COM applications.
*Base Class Library support, provides the types that the applications need at runtime.
CLR Architecture
For an application to run with in the Common Language Runtime and benefits from the managed execution environment, need to write the source code of application in a CLS- compliant Language.
The compilers of CLS-Compliant languages compile the source code and generate an intermediate code, called MSIL code metadata.
The MSIL contain a CPU-independent set of instructions, which describes how to load, store, initialize and call methods on objects. To execute the code, the runtime requires information about the codethat is in the Metadata. The MSIL code and Metadata are located in a Portable Executable(PE) file.
After the MSIL code and the metadata are loaded into the memory, the code manages calls the Entery-point method, which is the WinMain, Main or DllMain method. An Entery point method is the first method to be executed when an application runs. The IL to Native code JIT compiler Compiles the entery point method before it is executed.
The CLR ships with two JIT compilers, the normal compiler and an economy compiler. The normal compiler examines a method's IL and optimizes the resulting code.
The economy JIT compiler is typically used on machines, where the cost of using memory and CPU cycles is high(wingows CE). The economy compiler compiles code much faster than the normal compiler, however the native code produced by the economy compiler is net optimized and is significantly less efficient.
The .net framework is designed to fulfill the following object.
*To provide a consistent object-oriented programming environment.
*To provide a code-execution environment that:
-minimum software deployment and versonning conflict
-gaurantees safe code execution
-Elimination the performance problem of scripted or interpreted environment
-makes developer experience conflict across widely varying types of application.
*To build all communication on industrystandards, to ensure that code based on the .net framework can integrate with any other code.
The .net framework has two main components:
#The CLR(Common Language Run-Time)
#The .NET Framework LIbrary
The CLR is the foundation of the .net framework. The code that targets the run time is known as managed code. While the code that does not target the run-time s known as unmanaged code.
The .net framework can be used to develop the following type of application and services:
-Console Application.
-Windows GUI application (windows forms)
-ASP .NET Application
-XML Web Services
-Windows Services
-Services Components
MS.NET provide the following Services:
*Run-time environment, the .net framework
*Progarmming model for constructing HTML pages, named ASP.NET
*XML web services- A new way for internet services to expose function to any client
*windows forms- Anew way of writing Rich Client Application Using ther .NET framework
ADO.NET, which provide good support for database access within the .NET framework.
*Support for handling XMLDocuments and Streams.
*Standardized mechanism for signaling asyncronous events.
*Support for writing Multithreaded code
*Enhanced connection from one .NET system to another .NET system
*Support for run time discovery and invocation of an objects method and properties
THE Common Language Runtime
The CLR is software Engine that load and manages the execution of code on the .NET plateform.
The architecture of .NET realized that all procedural language required certain base functionality. for example, Memory Management.
So, instead of each language shipping with its own runtime, it would be better if all language could use a common runtime.
The CLR consists of Various Components that provide the runtime environment and services for application.
*Class loader, load classes into the runtime.
*MSIL to Native code Complier, convert MSIL code into Native code.
*code manager, Manages code during execution.
*Garbage collector, performs automatic memory management
*Security engine, enforces strict type cheacking.
*Thread support, provide multithreading support to application.
*Exception manager, provides a mechanism to catch and handle run-time exceptions.
*Debug Engine, allows to debug applications.
*COM Marshaler, allows .NET application to exchange data with COM applications.
*Base Class Library support, provides the types that the applications need at runtime.
