I wish all my blog readers , Happy Diwali!!! Let this festival lighten your dreamz and make you successful!!! Let me signify the value of this festival here…

*Significance of Diwali*

India is a land of festivals where you will see at least one major festival
each month.* Deepavali* (or Diwali) which literally means “rows of lamps” is
one of the four main festivals of India. Throughout the world all Hindus
celebrate Deepavali or Diwali with great pomp and enthusiasm.

The celebration of Diwali lasts six days, beginning on the 12th day of the
month of Kartik (as per the North Indian lunar calendar). The day before
Diwali, in order to evoke the grace of God, women fast. It is not that God
wants you to go hungry or takes pleasure in your suffering – the principle
is that you gain only by giving up. That evening, devotees worship Gomata
(the cow) and her calf and feed them special food. Women pray for the
welfare of the entire family. This holy day is called *Vasubaras*.

The first official day of Diwali falls on the 13th of Kartik. People set
about cleaning houses and shops, and decorating doorsteps and courtyards
with rangoli or multi-coloured designs. They purchase gold ornaments, new
vessels, clothes, and other such items. Devotees arise early in the morning
before sunrise and take oil baths. If possible, they wear new clothes. In
the evening, people worship coins representing wealth. Families decorate
houses and courtyards with lanterns giving a warm glow to the night. This
day of celebration is called* Dhantrayodashi* or* Dhanteras.*

The second day is called* Naraka Chaturdashi*. People take an oil bath in
the early morning and then in the night they light lamps and burn
firecrackers. People visit their relatives and friends, exchanging love and
sweets.

On the third day, people worship Lakshmi, the Goddess of wealth. People
decorate their houses with lit lamps and lanterns to welcome Lakshmi to
their home and hearts. On this day businessmen close old accounts and open
new accounts. The earth is lit up by lamps and the skies are coloured by the
multi-hued lights of fireworks.

In North India, the *Govardhana Puja* occurs on the fourth day of Diwali.
Devotees in the North build large mounds made of cow dung, symbolising
Govardhana – the mountain that Krishna lifted up with his finger to save the
villagers of Vrindavan from rain – and decorate and worship them. North
Indians observe this day as *Annakoot*, or the mountain of food.

The fifth day of the festival called *Bhaiyya Dooj* celebrates unique and
fun customs. Every man dines in his sister’s house, and, in return, presents
her with gifts. North India calls it Yama Dwitiya. Thousands of brothers and
sisters join hands and have a sacred bath in the river Yamuna.
The Legends

*Dhanteras *
The scriptures mention the divinity called Dhanvantari emerging from the
churning of the ocean holding a kalash (pot) filled with Amrit (ambrosia).
Due to the fact that Dhanvantari, who revealed the science of Ayurveda to
the world, first manifested on this day, all over India, doctors following
the Ayurvedic system of medicine organise joyful celebrations during the
annual Dhanvantari festival.

*Naraka Chaturdashi*
There is a legend about a king of Prag-Jyotishpur, named Narakasura. He was
a powerful king who misused power to harass his subjects. Sri Krishna
destroyed this oppressive asura king on this day. Unjustly imprisoned people
celebrated their freedom with friends and family. The citizens celebrated
their deliverance from Narkasura’s reign by lighting lamps.

*Sri Rama*
Deepavali falls on a no-moon day – in fact the darkest day of the year. The
illuminations and fireworks, joy and festivities, are to signify the victory
of divine forces over the powers of darkness. On Deepavali day, triumphant
Sri Rama is said to have returned to Ayodhya after defeating Ravana, the
asura king of Lanka.

*Goddess Lakshmi Devi*
The Puranas say that it was on this day that Goddess Lakshmi, who emerged
from the churning of the ocean of milk (Ksheera Sagara), married Lord
Vishnu, the repository of all divine qualities.

*Govardhana Puja*
In order to shelter the gopis and gopas and their cows from the torrential
rains sent by Indra, Krishna lifted a hill near Mathura called Govardhana
with his finger and sheltered all the people for a period of seven days
under it. By then Indra saw Krishna’s greatness and asked him for
forgiveness.

*Bhaiyya Dooj
*The river Yamuna and Yama, the God of Death, were brother and sister. As
they grew up they went their different ways. On this day Yama supposedly
visited his sister Yamuna, who in her joy at seeing her brother after such a
long interlude set up a feast for him. Pleased, Yama granted her a boon. He
declared that every man that receives a tilak or vermilion mark on the
forehead from his sister and presents her with lovely gifts on this day
would attain higher worlds.

*The message of Deepavali
*The traditional name of India is* Bharata* and Indians are *Bharatias* – or
‘those who revel in light’. During the night of Deepavali the myriad little
clay lamps (diyas) seem to silently send forth message of Deepavali: “Come,
let us remove darkness from the face of the earth.”

The dharma of fire is the same wherever it is: in a poor man’s house, in a
rich man’s house, in America, in Antarctica, or in the Himalayas. It gives
light and heat. The flame always points upwards. Even if we keep the lamp
upside down, the flame will burn upwards. The message is that our mind
should be focused on the * Atman*, the Self wherever we are. The lamps
remind us of our dharma to realise our divine nature.

“The Self is pure consicousness which is self-luminous. The cognition of all
objects arises from the light of pure Consciousness.” -*says Bhrihadaranyaka
Upanishad*

One lamp can light several others. You can even light another 1000 lamps,
and still the flame and the light of the first lamp will remain as it is. By
becoming manifold, the light looses nothing. The lights of Deepavali
represent Brahman and creation. It conveys the message of the mantra:

*”Purnamada Purnamidam Purnaat Purnamudachyate
Purnasya Purnamadaya Purnamevasishyate”
*

The rows of lamps teach yet another important lesson of unity. The light
that shines forth from the Sun, the moon, the stars, and fire is all the
same. To see and recognise that* one light*, the light of consciousness,
which is manifesting and pulsating in and through all of creation is the
goal of life. Thus, recognising all of creation to be an expression of your
true Self, spread the light of love and compassion.

The lights of Deepavali are displayed at the entrance doors, by the walls of
houses, in the streets and lanes. This means that the inner spiritual light
of the individual must be reflected outside. It should benefit society.
Passers-by may thereby be prevented from stumbling on their way to reach
their destination.
Feeding empty stomachs, lighting blown-out diyas and bringing light to those
whose lives are in darkness is the true spirit of Deepavali. This is true
prayer.

Time for Green Talk @ Sans Tech Press. I used to always think about global issues on nature and its protection, and today I thought of blogging some good tips and facts on environment and some harmfull products and how we can manage it.

GLASS

• Glass containers go from recycling bin to store shelf in as little as 30 days.
• An estimated 80% of recovered glass containers are made into new glass bottles.
• For every ton of glass recycled, over a ton of raw materials are saved, including 1,300 pounds of sand, 410 pounds of soda ash, 380 pounds of limestone, and 160 pounds of feldspar.
• Ninety percent of recycled glass is used to make new containers.
• Recycling glass helps to preserve natural resources while lessening the load on landfills—and helping communities avoid expensive disposal costs.
• Recycling one glass bottle saves enough energy to light a 100-watt bulb for four hours.
• Recycling glass lowers the melting temperature and saves 32% of the energy needed for production of new glass.

PLASTIC

• If we recycled every plastic bottle we used, we would keep 2 billion tons of plastic out of landfills.
• Recycling a pound of PET saves approximately 12,000 BTUs.
• It takes 25 two-liter plastic soft drink bottles to make a sweater.
• It takes two plastic soft drink bottles to make enough polyester fiber for a baseball cap.
• It takes 35 two liter plastic soft drink bottles to make 1 sleeping bag.
• Americans go through 2.5 million plastic bottles every hour.

ALUMINIUM

• If we recycled the 48 billion aluminum cans that we throw away each year, we could save the equivalent of 24 million barrels of oil.
• Recycling aluminum cans saves precious natural resources, energy, time and money – all for a good cause – helping out the earth, as well as the economy and local communities.
• Aluminum is a sustainable metal and can be recycled over and over again.
• In 2003, 54 billion cans were recycled, saving the energy equivalent of 15 million barrels of crude oil (America’s entire gas consumption for one day). It takes about 6 weeks total to manufacture, fill, sell, recycle, and then remanufacture a beverage can.
• The energy saved from recycling one aluminum drink can will run your TV for 3 hours.
• If we recycle the aluminum trash that Americans throw away, we could rebuild the entire US airline fleet every three months.
• Recycling one aluminum can saves the amount of energy to light one 100-watt bulb for 20 hours or run a TV for 3 hours.
• In America, 1,500 aluminum cans are recycled every second.

In fact, the prestigious Princeton College Review and Kaplan’s College Guide now have sections devoted to how “green” a particular college or university is today. I wish all the colleges in our Country also to take up Green Projects within their locale and make the earth a better place for the future to rejoice.

Recently Gary, Sun Microsystems blogged on Java developers advising to students and I found the article interesting and Since 1999, java.sun.com writers have interviewed Java developers from diverse backgrounds and solicited their advice for students. In this article, 11 top Java developers share the fruits of long experience. Let me CTRL+C and CTRL+V all those excellent stuffs here.

Joshua Bloch: Write Lots of Code

When we ask Java developers about their favorite Java book, they repeatedly refer to Effective Java by Joshua Bloch. So his advice seems like a good place to start.

Chief Java architect at Google, Joshua Bloch is well known as the author of Effective Java, now in its second edition, and coauthor with Neal Gafter of Java Puzzlers.In a former life as a senior staff engineer at Sun Microsystems and an architect in the core Java platform group, Josh Bloch designed and implemented the award-winning Java Collections Framework and contributed to many other parts of the platform, including the java.math package.

Bloch holds a Ph.D. in computer science from Carnegie-Mellon University, where during the defense of his dissertation, which was open to the public, he arranged for his mother to ask a long technical question that he answered flawlessly after saying, “Awww, Mom!” He responded to another planted question with a rap song, backed by a recorded rhythm track played on a boom box concealed under the desk.

Bloch is fond of saying, “Computer science is an immature discipline, and I aim to keep it that way.”

Write lots of code. Have fun with it! Collaborate with people who are more experienced than you and learn from them. Join an open-source project. Code reviews are a great way to learn. Don’t be embarrassed when people find problems in your code; fix them and have fun watching your code and your skills improve. Oh, yeah, and go buy a copy of Effective Java.

Your book Effective Java is written for experienced Java developers. Do you have any advice for how a computer science major in college might benefit from the book? Or an experienced developer moving from another language to Java?

Many programmers find it useful to keep a copy at their desk so they can look at the code examples and such while they work. Also I’ve seen people use item references in comments explaining their design decisions. Needless to say, I’m honored that they’ve done so. As for programmers moving from another language, I think they’d do well to read a quick introduction to Java before tackling my book. Peter Sestoft’s Java Precisely would be an excellent choice.

What are some things you wish you’d learned in engineering school?

I wish I’d learned to play guitar better than I do, which isn’t very well. I wish I’d learned a foreign language. And art history. Also, it would have been nice to learn something about business and finance. That said, Columbia did very well by me. But I would encourage undergraduates to take the opportunity to acquire breadth while they still have time for it. They’ll have plenty of time for depth later.

Tor Norbye

Tor Norbye is a principal engineer at Sun Microsystems, where he has worked on development tools since 1996, most recently on the Ruby and JavaScript editors in the NetBeans IDE. He is also a cohost of the weekly Java Posse podcast and specification lead for Java Specification Request (JSR) 273. He has a master’s degree in computer science from Stanford University, where his classmates included Google cofounder Larry Page.

Three things.

1. Learn to use your tools. And I don’t mean just enough to get by. I mean really learn how to use your tools. Become an expert user. After you’ve learned all the items in menus and context menus, and after you’ve learned the most important key bindings, then Google “tips and tricks” for your IDE.

Learn how to use built-in code templates. Learn how to use the quick fixes. For example, in NetBeans, you don’t have to write the left-hand side in assignments when you’re calling a method. Just write this:

"foo".indexOf("o");

Move the caret inside indexOf, the method name, and type Alt-Enter. Assuming you’re calling a method that has a return value, and you’re not already reading the return value, NetBeans will generate the left-hand side of the assignment — including the type declaration — for you:

int indexOf = "foo".indexOf("o");

At this point, you’re in code-template-editing mode, so you can type a new name for the result variable.

Similarly in NetBeans, try typing newo and hit Tab. Go ahead. Try it.

And that’s just the editor. You also need to know how to properly use the debugger, profiler, and version-control integration.

2. Learn how to make trade-offs. When you’re a computer science student, you typically have programming assignments where the inputs and outputs are pretty clear, and the scope is limited. You can write a “perfect” program that’s well documented, elegant, fully tested, and correct. In the software industry, that’s often not the case. There’s a never-ending list of requests. You’ve often taken over somebody else’s code, and you’re not thrilled with the way it was written.

Then, at least for mature products, there’s also a pretty large number of low-priority bugs — bugs that are real but of limited impact, so they didn’t hold up the last release. What is more important: Add a feature that will benefit a lot of users, or fix a bug that affects almost nobody? Rewrite the code to make it more maintainable, something most programmers long to do? Spend time helping users of the current shipping version of the software? There aren’t enough resources to do everything, but they’re all important. So you end up having to time-slice to address at least some of these, and in addition, make hard choices.

And even if you have perfect time-management skills, or your manager makes priority choices for you, at the end of the day, as an engineer, the software discipline is also filled with trade-off choices. To speed up some code, you can make it faster by adding a cache — but that drives up memory consumption. Is that trade-off worthwhile? Congratulations, it’s your job to answer that one.

3. Finally, learn the platform APIs. There’s a huge number of well-written and performant classes in the Java platform, along with some utility classes around them. Make sure you have a good grasp of all the available functionality in the platform before you write your own code. For example, yes, there’s no reverse() method on the java.util.List interface. But not so fast — don’t write it yourself. There’s a Collections class that contains a lot of utility methods that operate on collections, like List, and it provides a reverse() method.

And if you’re building on top of a rich-client platform like NetBeans, or using other libraries like the Google Collections API or some of the Apache libraries, there’s a wealth of additional APIs you can reuse. For example, when I write my unit tests for NetBeans code, I can rely upon additional testing infrastructure written for NetBeans that make it simple to add performance-related tests or memory leak tests.

Chet Haase is a senior computer scientist on the Flex SDK team at Adobe, focusing on graphics issues and features. In a former life, at the time of the following interview, he worked for Sun Microsystems as a client architect in the desktop Java group. He is coauthor with Romain Guy of the book Filthy Rich Clients: Developing Animated and Graphical Effects for Desktop Java Applications. He is also the author of a humor book, When I am King.What advice do you have for someone who wants to have a career creating graphics software?

Take the math courses you need. It doesn’t need to be higher-level stuff, but I’ve leaned heavily on linear algebra and some amount of calculus for a lot of what I’ve done.

What advice would you give to a programmer new to the Java programming language?

Don’t use line numbers. Don’t put your entire application in one method. Trust the garbage collector to do its job.

Is there anything you wished you’d learned in engineering school?

I actually could name lots of things I learned in engineering school that I wish I hadn’t wasted my time on. One big difference is that you work on new and small projects in school and huge and old projects in the real world.

For example, the code I work on at Sun is part of the JDK library that has been in constant development for well over 10 years. Frequently, the hard part of any fix or feature is not the functionality of the fix or feature itself, but rather how it integrates with all of the code around it. Does the fix break compatibility? Does it conflict with anything going on around it? Do you understand the context of the code? This is something that’s particularly difficult in old code bases in which the original developers have all left long ago. Does your team agree with and understand the changes?

I don’t know how to cover such topics in school effectively, especially in the tight time frames of individual classes, but the more students are exposed to team development, versus individual projects, the easier it is for them to become integrated into team development in the real world.

Related to team development, I think code reviews would be a great tool for school. I’ve probably learned more about coding practices and the code I work on through the reviews we do in the client group than in coding itself. You learn how others do things, you get objective perspectives on how you do things, and everyone comes to a shared understanding of how teams should develop common code.

Ben Galbraith: Interact With an Expert

Ben Galbraith is a frequent speaker, independent consultant, conference producer, and author of several books. He is an experienced CEO, CTO, and software architect, and was hired in October 2008 by Mozilla to lead an initiative to create web development tools that will make life easier for web developers. He wrote his first computer program at age 6, started his first business at age 10, and entered the IT workforce at age 12. For the past few years, he’s been professionally coding in the Java language and was the top-rated speaker at the 2006 JavaOne conference.

I believe all software engineers should learn about how to ensure that their users have a quality experience. I covered some aspects of that topic in my 2008 JavaOne conference talk Creating a Compelling User Experience.

I think the roles of a software developer are a bit up in the air at the moment. Not many years ago, we developers were sort of gatekeepers: No software was created unless we wrote the code, and we interpreted designs and direction we were given as we thought made sense.

Now, there are a bunch of efforts by the platform vendors — Microsoft, Adobe, Sun, and so on — to empower a less technical audience to create software. Microsoft Expression, Adobe Thermos, and perhaps some future tool from Sun are all about letting a more creative, less technical person create user interfaces that in the past would have required all kinds of code and engineering effort.

This reflects an emerging trend in recent years to reify a new, highly technical designer, often called an interaction designer, as the leading force in software development, rather than engineers. To get a fascinating look at this effort, Google for a transcript of Alan Cooper’s keynote at the Interaction08 conference.

So how will software be developed tomorrow? And where do new entrants fit into all of this? Lots of different people can feel passionate about being involved in the creation of beautiful, compelling software. I think such people have got to figure out whether they are at heart an engineer — if they get their kicks solving hard technical problems — or if they are something else.

There will always be opportunities for great engineers, but as I said earlier, I think the number of these opportunities will shrink as other, less technical personnel play larger roles in the software-development process, using more productive, higher-level tools and frameworks than we have used in the past.

Newcomers should find one or more mentors as soon as you can. Google makes finding information easier than ever, but nothing beats interacting with an expert.

Masood Mortazavi: Start Simple and Keep Learning

Masood Mortazavi, a software engineering manager at Sun, started his work with the company on the Java EE development team and as an expert in continuous availability issues and telecom collaborations with the Java software group. In recent years, he’s managed teams of engineers who contribute to open-source databases such as Apache/Derby, PostgreSQL, and MySQL.He has a B.S. (U.C. San Diego) and an M.S. (U.C. Davis) in applied and chemical engineering, and a Ph.D. in computational fluid dynamics with a dissertation titled Vortex-Vortex Interactions and PDF Methods (U.C. Davis). In addition, he has a master’s degree in journalism (U.C. Berkeley) and an M.B.A. (U.C. Berkeley), and he spent several years pursuing a second Ph.D. in the Graduate Group in Logic and Methodology of Science (math, philosophy, and computer science) at U.C. Berkeley, with a focus on foundations of math, theories of computation, and philosophy. He stopped work on his second Ph.D. soon after joining Sun in 1999.

Start simple. Learn the basics of the language, and even before that, make simple modifications to existing, running programs and see what happens.

Tap into the amazing online documentation resources.

Write the most advanced program you can concoct, choosing something that tickles your imagination, to stretch your own limits, and if you can, to stretch the limits of the Java platform.

Get involved and write programs for some commercial or open-source software that matters and that people actually use.

As you advance, select a great IDE to work with, say NetBeans. (Sometimes this is necessary earlier.)

Keep learning about the systemic use of Java in system programming. There are lots of pleasant surprises there.

Don’t forget that billions of dollars of revenue have been generated and millions of people have been employed because someone at Sun Microsystems invented Java, and a group of dedicated engineers kept producing innovations around it. So contribute to the goodness.

Can you name some things you wish you’d learned in engineering school?

Yes — more design, more marketing, more business, more economics, more management and organizational theory, and finally, more philosophy and art — all in that order or some other combination, to create a good mix of ideas.

Unfortunately, while going through four different University of California campuses, Stanford University, and some other schools as an engineering student and researcher, I didn’t observe an interest in bringing these other disciplines into the life of an engineering student. Unfortunately, students are kept in the silos of their own academic disciplines. Even in science and technology, they are divided into various minidisciplines with very little cross-pollination.

I myself did have some lucky breaks. For example, my Ph.D. advisor, Dr. Wolfgang Kollmann, was very open to my exploration of various areas. While conducting research in computational fluid dynamics with him, I also took advanced courses in biochemistry, embryology, linguistics, and linguistic neurophysiology, along with courses in art, philosophy, economics, and political science. I also worked on the university paper.

This is a very general problem in American education that probably exists elsewhere as well. We’re “mass producing” technologists and scientists with narrow focus and with little care for their development as leaders and creative inventors who can help us to disclose new ways of living, working, and prospering.

European engineering schools have had a tradition of teaching these other disciplines along with engineering. We cannot compete globally unless we train top-notch engineers who have a broad perspective about how their technical work fits into other domains and who understand the institutional place for technology. Otherwise, it’s highly unlikely that we will be able to continue to tap technology for the general social good, beyond the production of gadgets.

Raghavan Srinivas: Don’t Be Overwhelmed

Raghavan “Rags” Srinivas, was, until recently, a technology evangelist at Sun Microsystems, focusing on new technology directions and trends. With 20 years as a software developer and 7 years in technology evangelism, his general area of interest is distributed systems, specializing in interoperability, mobility, and security. He publishes a standards column and has represented Sun at a number of standards bodies. Rags holds a master’s degree in computer science from the Center of Advanced Computer Studies at the University of Louisiana at Lafayette.

Don’t be overwhelmed by the language or the platform. If you break it down, the basics of the language are based on object-oriented programming, threading, concurrency, and event-driven programming. It’s necessary to become a master of these concepts since the rest of your career will depend on this foundation.

After that, one can specialize in one or multiple areas, which might involve designing GUIs, doing web stuff, JDBC programming, EJB/JMS programming, security, and so on. If one’s foundation is strong, it’s fairly easy to move from one area to another with relative ease.

Read the full interview with Raghavan Srinivas.

Cay Horstmann: First, Don’t Panic

Cay Horstmann is professor of computer science at San Jose State University in California. He was named a Java Champion in 2005, an award given to individuals working outside of Sun who have received special recognition from Java technology developers across industry, academia, Java User Groups (JUGs), and the larger community. He has a Ph.D. in mathematics from the University of Michigan, is the author of Core Java, and coauthor of Core JavaServer Faces.

First, don’t panic. When students first see the API with thousands of classes, they despair. I used to be able to tell them, “That’s OK, at least the language itself is very simple.” But that was before this:

static <T extends Object & Comparable<? super T>> T Collections.max(Collection<? extends T> coll

As a student, you need to stay within a safe subset of the Java language and the API so that you can use it as a tool to learn some good computer science.

Next, code. Professional programmers often forget how hard it is for most beginners to actually program. It’s so unlike most activities. The computer is unforgiving. When you’re wrong, you’re told very quickly that you were sloppy or stupid — not a good thing for a fragile ego. And when you are wrong, you need to stop and think. Random tinkering rarely gets you anywhere.

This is a really hard sell to today’s students. Your ego isn’t stroked very much, and you’ll get a headache trying to fix your mistakes. A career in divorce law sounds so much more attractive. But when you succeed, it sure feels good. The trick is to get students to that point.

Last summer at a faculty summit at Google, bigwig professors from big-name universities expounded on their efforts to reform the computer science curriculum and make it less focused on programming. The organizers from Google said, “That’s all fine and good, as long as the students can code when they graduate.”

Arun Gupta: Try Different IDEs

Arun Gupta is a technology evangelist for web services and Web 2.0 apps at Sun. He was the spec lead for APIs in the Java platform, a committer in multiple open-source projects, a participant in standards bodies, and a contributor to Java EE and SE releases. He holds a B.S. in electronics and an M.S. in computer science, both from Delhi University, India.As a beginner, I used a lot of vi (visual editor). But now I’ve been using IDEs, like the NetBeans IDE, for the past couple of years, and I must say my productivity has gone up multifold. Specifically, features like boilerplate text, refactoring, and debugging are much easier to work with in IDEs than manually or using pluggable scripts in the vi environment.

For instance, if I’m writing a Java bean, then I need to give the class name, field names, and their types, and the rest of the boilerplate text of getters/setters is generated for me. I can set up a breakpoint when a particular exception is thrown, and the IDE will halt whenever that exception is thrown. I can change a class name or move it to a different package name, and all of its references are updated accordingly. These are simple but powerful examples.

And some IDEs have very powerful features such as remote debugging. The IDEs keep me focused on the logic part of my code and take care of code logistics for me. I really recommend that new users try out different IDEs and pick one of their choice. For instance, the NetBeans IDE is available free.

In school, I didn’t realize the importance of documenting. I would go through design, develop, and test cycles but would not document the design decisions or add comments in the code. This would make even my own code unreadable to me, sometimes a few weeks after I wrote it. UML designing and adding Javadocs liberally through the code has helped me write readable code.

Secondly, I wish we had more participation from industry in school. It would have been good for someone currently working in the industry to talk to us about industry trends, practices, and standards.

Every time I visit Delhi, I go back to my school, meet the faculty, and mingle with the students. I give a presentation on the latest industry standards in my field, discuss the importance of coding standards, and show code samples. During my last visit, I started working with some students on a new web services-related project and hope to inculcate in them the great coding practices that we follow at Sun.

Rick Cattell: Good Technology Is Only 10% of Success

Rick Cattell is an independent consultant in database systems and in engineering management. He was previously a Distinguished Engineer at Sun Microsystems and has worked most recently on open-source database systems and proprietary innovations in database systems. He served for more than 20 years at Sun Microsystems in management and senior technical roles, and for more than 10 years in research at Xerox PARC and at Carnegie-Mellon University, where he received his Ph.D. in computer science.Cattell is best known for his contributions to middleware and database systems — particularly enterprise Java, object-oriented databases, object/relational mappings, and database interfaces. The author of several dozen papers and six books, Cattell is also known for a talk titled “Things I Wish I’d Learned in Engineering School,” which he has presented at universities around the United States.

First, I didn’t realize how important it was, for me at least, to work on things that people are actually going to use. I didn’t realize that it wasn’t very satisfying to write research papers or even to build working systems if the results of my labor weren’t going to be used in the real world.

I also didn’t realize that good technology is only 10% of success. If your management doesn’t know how to manage a successful engineering project, or your marketing department doesn’t know how to access the customers, or doesn’t tell you what the customer wants, or if your lawyers don’t handle your intellectual property correctly, or if the chief architect doesn’t have the ability to create a consistent and simple architecture, then your work can be for naught, and you can spend years building things that never see the light of day.

Chuk-Munn Lee: Choose an Area of Your Immediate Need

Chuk-Munn Lee has been programming in the Java language since 1996, when he first joined Sun Microsystems in Hong Kong. Now based in Singapore, he works as a Sun Java technology evangelist and frequently helps individual developers and software vendors to architect and prototype both their server and desktop-based Java applications. His more recent work has focused on Swing-based client applications. He also keeps ISVs up-to-date on the latest developments in the Java platform and what’s on the horizon.

He graduated in 1987 from the Royal Melbourne Institute of Technology in Melbourne, Australia, where his favorite subject was compiler theory.

First and foremost, I would suggest exploiting the web. There’s tons of learning material. There are forums to post your queries and download open-source code. Getting books is another good way, but I’ve had people complain to me that the moment they buy any technology-related book, it’s already out-of-date. I suggest trying the local library or subscribing to something like Safari Bookshelf.

For a beginner, the plethora of Java APIs can be quite intimidating. Choose an area of your immediate need, for example, web programming, servlet/JSP/JSF, GUI, Swing, persistence, JDBC/JDO (Java Data Objects)/CMP (container-managed persistence), or what have you. Work on a project that gives you experience in using the API, the development tools, and the runtime environment. Keep the project manageable — I tend to pick something that is fun and that I can complete in three months max.

Tom Ball: Programming Is Still a Craft

Tom Ball is a software engineer at Google, working on Java development tools. He began working with Java in 1994 as part of Sun’s JDK, AWT, Swing, Jackpot, and NetBeans teams, and contributed to the JavaFX Script compiler team. He has no formal university education.Programming is still a craft, so the more you can work with senior developers, the more you’ll learn of the important stuff the computer science professors don’t teach. If you have time, join an open-source project and help out in any way you can to learn and to build credibility with your peers.

But don’t join every project you find interesting. I’ve seen many enthusiastic newcomers spread themselves too thin, overcommit, and thus not be taken seriously.

Finally, get to know the various Java communities through their forums and blogs, then join in. We’re a great group!

I wish all my fellow students to make sure that they follow all these tips to leverage their programming to code for the future and to code the future!!!!!

From days of yore , education in India has been a very integral part of Ones life. Indian culture is stepped in education of different types – from the age old Gurukul system to the modern Montessori methods. Traditionally Education in India is looked upon by everyone as a holistic experience.

Engineering has become a core area where students step into in a large numbers. For Engineering Students  especially for Computer Science and IT students  it is important to pad up their industry skill-set before they are placed to compete in the global arena. Students nowadays are placed in their third year itself and the final year projects are being carried out in their fourth year leaving behind their practical skills during campus placements. Keeping this in mind many students have started doing mini projects. In some of the technical groups in which I am a member, nowadays I see my fellow students started with their mini projects.

Mini projects develops practical skills in students. In spite of all the theory we learn, the industry should also know our ability in completing projects using our own initiative. I am fascinated with the latest trends in attending internships from the companies as we get to learn lots more from these.

On-line mini Projects through sourceforge.net and other open source development initiatives will surely add value to our experience cloud. These projects would definitely benefit ourselves, but the very least we can do in our second and third year of our engineering would be to work on mini projects and present papers.

Open Source University Meet-Up (OSUM) pronounced  as Awesome is a perfect Student Developer’s Community fostering all Open Source tools and training Students. I am fascinated to share things with my fellow beings, including my knowledge and experiences. This is Why I am also crazy about Open Source, as It allows us to share, recreate and lot’s more. There is no hassles in reviewing Copyrights. OSUM helps a Student developers community in the college to make sure that the members gets trained and well incubated with industry training before they are let out in the corporate world.

Fabulous February started with a Live webcast from California. I agreed to my Invitation to attend the event. It was a wednesday (3/2/09)evening, when I had to review my Laptop for Java Updates and other stuffs for the event. The event was about to begin at 10PM and I launched  my browser and found Mr. Aruna Gupta, GlassFish Evangelist, Sun Microsystems, welcoming the session attendees. It was a great pleasure for me to  attend the Webinar and I thank Mr. Arun Gupta for his talk on GlassFish. I have blogged all about GlassFish which I have carried as notes after the session. I found GlassFish interesting and this Webinar has changed my Application Server from Apache to Glassfish in deploying all my scripts.

GlassFish is a vibrant community building high-quality, open source software. The main deliverable are the GlassFish application server, the Java Platform, Enterprise Edition(java EE) reference implementation, and the Java Persistence API reference implementation.

Developing Server based Application with the help of clear application specification of Java EE 5 helps us to deploy the application with 100% uptime. The Glassfish which is built on the Java EE compliance is portable. Java EE 5 has API, Technology specification, Production-quality implementation, Comptability Test Suite, themed on ease of development.Here POJO ( Plain Old Java Object) based programming gives us more freedom and fewer requirement in implementation level. The Latest inclusion DRY( Don’t Repeat Yourself) mechanism allows all the connection strings of the database from the application level to be kept in a songle file making debugging easier and faster access.

The latest Call Flow Monitoring allows us to enable the monitoring of the app server to track the time spent on the EJB Container, Web Container, and EJB Application and lots more enabling us to improve the performance. There is a special Request Time Distribution column showing the time spent on each requests.

GlassFish TimeLine

June 2005           -    GlassFish Launch

May 2007            -   Version 1 ( With Java EE 5)

Sept 2007            -   Version2

Nov 2008             -   Prelude

Jan 2009              -   Version2.1 (latest)

In Jan 209 500 bugs were fixed to improve stability and it was Java EE 5 Compliance supporting JSP,Servlet, EJB and lots more.

GlassFish also supports dynamic Languages and framework like JRuby, Merb, Rails, Ruby, Groovy, Grails, Python, Jython, django, JavaScript and lots more. Quercus should be used for deploying PHP apps in GlassFish.

I’ll chart the “To Do” steps to install GlassFish and Deploy it in your Local Machine…

Steps to Deploy GlassFish in your Machine

—>Download GlassFish V3 Prelude

—>Unzip GlassFish-V3-Prelude-V28C.Zip

—>Start: asadmin start domain

It is very simple to install and deploy the Application Server.

We can access the admin console @ http://localhost:4848/

and deploy our applications @ http://localhost:8080

Some of the Cool Features in GlassFish V3

—>It can retain session data across HTTP deploys

—>Embeddable- Runs in -VM

—>Supports Dynamic Languages

—>Fastest Start/up Time-2-3 Seconds

—>Support World Class IDE’s such as NETBEANS 6.5 and Eclipse

—>Extensible, Modular, ease to use

—>Failover Administration, monitoring, messaging, Persistence

Plan for GlassFish V3

GlassFish v3 is the next major release of the GlassFish Application Server and is currently under development by the GlassFish Community. GlassFish v3 has a modular, lightweight, extensible architecture. The goals are to provide the following:

• An open, modular, extensible platform
• A fast, easy, reliable application server
• An enterprise-ready application server with massive scalability and sophisticated administration
• Product updates and add-ons through the industry-strength
• Support for OSGi
• Support for dynamic languages such as Ruby and Groovy
• Support for Java EE 6

I consider GlassFish as an excellent alternative to lesser featured Tomcat and JBOSS. Netbeans 6.5 comes with GlassFish V2 and V3 bunduled, which makes developing and deploying application easy and effective. GlassFish is the Fastest Open Source Application sever. So from Student to Enterprise, I recommend GlassFish as the Best Application Server for all your Web Apps.

Tech Talk by Arun Gupta on Ruby/GlassFish

Sun Microsystems hosted the 30th Super Happy Dev House at it’s Executive Briefing center in Menlo Park, CA. Over 300 super smart developers gathered to geek it out on the next generation of technologies. During the Lightening Talk period, Arun Gupta (Super Technology Guru Extraordinaire from Sun) talked about Ruby and GlassFish. He ran out of time before being able to showcase Project Kenai, built using Ruby-on-Rails, JRuby, GlassFish, MySQL, and OpenSolaris

We probably know Google from the products on the Internet, like Google Search, Gmail, Orkut and Google Maps. Soon, they may even visit a town near you, to give you a first hand experience of what the Internet has to offer you.

The Internet Bus Project is an attempt educate people about what the Internet is, and how it may be beneficial to their lives, by taking the Internet experience to them through a customised Internet-enabled bus, which will travel to several towns and cities across India.

The bus started at Chennai recently and there was lots of people who realised the essence of the work carried out by Google and supported it. Due to the problem in Srilanka, the local goverment here at Chennai declared bandth and the roads were left with none. If this has not happened now, Iam sure that this project would have reached a wider audience.

Fortunately Google have planned this project to take place in every town in the state and the Internet Bus is now on the roads heading straight to vellore. I am sure that people and fellow students at vellore will be able to make use of this event to realise and Explore the World of Internet.

Here is the schedule that the Google Internet Bus will follow:

February
03 Feb Chennai
05 Feb Vellore
06 Feb Krishnagiri
07 Feb Salem
11 Feb Erode
12 Feb Tiruppur
14 Feb Coimbatore
18 Feb Dindigul
19 Feb Madurai
23 Feb Tirunelveli
25 Feb Nagercoil
27 Feb Tuticorin

March
02 Mar Pudukkottai
03 Mar Tiruchirappalli
06 Mar Thanjavur
08 Mar Kumbakonam
10 Mar Neyveli
12 Mar Cuddalore
13 Mar Tiruvannamalai

All my gadgets from my mobile phone, laptop to my personalized desktop, most of it is loaded with Open Source Tools and software.Predominantly these software are lightweight, ease to deploy and maintain. The performance of the host increases many folds when holding open tools in it. Some records are big. Some are amazing. And then there are some, that are simply crazy. Here is one which I received for helping Mozilla browser ( Firefox 3) set the World Record.(record for most software downloaded in 24 hours)

HAPPY NEW YEAR 2009

I have always been fascinated with the endings more than the beginnings. They give me an opportunity to prepare for what is going to come next.

That is why December 31 fascinates me more than January 1 each year. There is something unique about it.

H ours of happy times with friends and family
A bundant time for relaxation
P rosperity
P lenty of love when you need it the most
Y outhful excitement at lifes simple pleasures

N ights of restful slumber (you know – dont’ worry be happy)
E verything you need
W ishing you love and light

Y ears and years of good health
E njoyment and mirth
A angels to watch over you
R embrances of a happy years!

We look back to our yesterday to ensure that when we peep into our tomorrow there is a certain hope to live for that day. We hope that a certain past is not repeated in the coming 365 days.

I wish all my blog readers, friends, well wishers and all the wonderfull heart in the world a “HAPPY AND PROSPEROUS NEW YEAR 2009″.

Recently all Oracle certified Professionals were given a chance to migrate to Microsoft SQL 2008. The moment I deployed SQL 2008, I found it was a excellent platform for all DBA’s. I realized SQL provided me the perfect stage to exhibit all kind of services from Analytical to BI.

Comparing ORACLE 11g to MS SQL 2008, I found all the additional services as built-in feature in MS SQL 2008, but not in ORACLE 11g.Secure, robust, easy to maintain, cost-effective solution is provided by SQL 2008. SQL 2008 are launched in different flavors, and let me chart all those here;

Express Edition, Workgroup Edition, Standard Edition, Enterprise Edition, Developer Edition, Web Edition, Mobile Edition.

I will advise Enterprise level to all, as it has no CPU limit and unlimited storage. Each flavor is special in its own.  Watch this video and you will know what peers think on SQL 2008.

Let’s get some Taste Teasers!!!
