Like all computer languages, JavaScript has certain
advantages and disadvantages. Many of the pros and cons are
related to being a client-side language.
Advantages of JavaScript
* Speed. Being client-side, JavaScript is very fast
because any code functions can be run immediately instead of
having to contact the server and wait for an answer.
* Simplicity. JavaScript is relatively simple to learn
and implement.
* Versatility. JavaScript plays nicely with other
languages and can be used in a huge variety of applications.
Unlike PHP or SSI scripts, JavaScript can be inserted into
any web page regardless of the file extension. JavaScript
can also be used inside scripts written in other languages
such as Perl and PHP.
* Server Load. Being client-side reduces the demand on
the website server.
Disadvantages of JavaScript
* Security. Because the code executes on the users'
computer, in some cases it can be exploited for malicious
purposes. This is one reason some people choose to disable
JavaScript.
* Reliance on End User. JavaScript is sometimes
interpreted differently by different browsers. Whereas
server-side scripts will always produce the same output,
client-side scripts can be a little unpredictable. Don't be
overly concerned by this though - as long as you test your
script in all the major browsers you should be safe.

Dr. Venkat Subramaniam to Speak on Debugging Ajax, Agile
Development, Test Driven Development in .NET, Programming Groovy
Developing Ajax applications is a lot of fun, up until
things stop working. In addition to the general programming
complexities, you need to deal with browser differences,
JavaScript, and framework idiosyncrasies. alert() often
helps only to get our blood pressure high. Agile
practitioner Venkat Subramaniam is coming back this summer
to India's biggest summit for the developer ecosystem -
Great Indian Developer Summit
(http://www.developersummit.com/) with a two-prong approach
to debugging Ajax. The first is a proactive step towards
testing and developing Ajax applications in smaller steps.
Second, when bugs still manage to creep in, exploring what
tools can help to fix those bugs and keep your BP normal at
the same time.
The co-author of the award-winning book 'Practices of an
Agile Developer' Grails, along with its facility to develop
test driven, is a killer combination, along with agile
development, for rapidly developing web applications. Venkat
will teach how to develop fully functional web application
in Grails while also utilizing other capabilities like Ajax.
Venkat will be covering some tricky features of Java, those
that can trip you over, and also look at some ways to
improve your Java code. He will also step through the
benefits of using Groovy, its features, how you can take
advantage of metaprogramming and intermix with Java.
The founder of Agile Developer, Inc., will also conduct two
3-hour workshops -- on developing a sample application using
Test Driven Development and; differentiating between
different Domain Specific Languages (DSLs), their
characteristics and how to edit, parse, and validate
external DSLs using Java based tools.

Write a main method that prompts the user to enter the starting population, birth and death rates, and the number of years. The input birth and death rates cannot be negative, the starting population cannot be less than 2, and the number of years greater than 0. If the user enters an invalid value, this program will prompt user to re-enter the value until a valid value has been read. When all input values are valid, call on the methods above to compute estimated population and print result.

Hello Friends !!! I am RAJAT AGRAWAL, All Saints' College of Technology, Bhopal ( M.P. ) I just want to share my experience of getting placed at Consagous Technologies. On 9th June 2012 there was an close campus drive of Consagous Technologies in our college. I was very excited to take part in it. Firstly, they started with a seminar, a small introduction about the company. Then the placement process started. The recruitment process of Consagous had three rounds. 1. Written test 2. Group discussion 3. Technical interview & HR Interview Written Test : It was objective type with 50 questions in 60 mins. The written test paper had three sets set A , set B and set C. I got set B. Basically the question were from network connection with database ,output of programs on C, C++, java, asp.net, php , data structure and Aptitude questions included topics like Time & Distance, simple interest ,average, Percentage, Ratio & Proportion etc.There was no negative marking in the written test. Some of them which I remember are- 1. What command in UNIX run on backgroung. 2. The groups of students are divided into 2class room. If 10students are shifted from class A to Class B then no of students in both class are equal. If 10 Students are shifted from class B to Class A then no of students in class A is Double to the no of students in Class B. Find the total no of students? 3. The time taken by boat to travel 4 meters dowmstream is 4 hours 48 min and that the upstream 4 hours .Find the speed of the boat in still water and the speed of the stream. 4. And many more…. Then after few hours the result of written test was announced , and fortunately I was selected among the 80- 100 other students. After written test 21 students were shortlisted and went through 2nd round . GD Round: In this round , all 21 students divided into two teams and went through group discussion process. Topic of our GD was “Spirituality and Technology” and it held for 15 to 20 min. It was the very nice discussion and most of them took part in it. After GD round 11 students were shortlisted. Then the next round was Technical and HR interview. HR and Technical Interview: Finally after 2nd Round I had been selected for HR and Technical Interview Round .At that time also I was full of excitement for my PI , though nervous also. I just prayed to God , took my parents name and entered in the room, As I entered I saw three people there inside the room I wished all of them, and they offered me the chair, I replied with thank you sir thank you mam. HR questions: • Introduce yourself • Why u want to be a software engineer? • why u want to join consagous? • Why do we take you in consagous? • Tell me 5 negative points of your's? • Tell me the name of CEO of Google, Facebook? Technical question: • what is object –oriented programming? • Tell me about your major project? • Features of OOPS n Advantage of Oops? • Difference between Router $ Switch? And many more…… All you have to be confident and have positive attitude during the interview. Really it was a very good experience with HR sir and with his team. And just after half an hour the results had been declared , 5 students were selected and fortunately with God Grace I was one of them, that was one of the most cherishable moment of my life. After that we have a photograph with HR Sir & CEO Sir. I always remember one thing We Will..... Do It...........!!!!! I would like to thank Consagous Technologies to give me such a big opportunity to work with them,thank you so much.!
