ಮುಂಗಾರು ಮಳೆಯೇ.. ಏನು ನಿನ್ನ ಹನಿಗಳ ಲೀಲೆ
ನಿನ್ನ ಮುಗಿಲ ಸಾಲೆ, ಧರೆಯ ಕೊರಳ ಪ್ರೇಮದ ಮಾಲೆ ಸುರಿವ ಒಲುಮೆ ಆ ಜಡಿ ಮಳೆಗೆ, ಪ್ರೀತಿ ಮೂಡಿದೆ...
ಯಾವ ಚಿಪ್ಪಿನಲ್ಲಿ , ಯಾವ ಹನಿಯು ಮುತ್ತಾಗುವುದೋ ... ಒಲವು ಎಲ್ಲಿ ಕುಡಿಯೊಡೆಯುವುದೋ, ತಿಳಿಯದಾಗಿದೆ ...

ಮುಂಗಾರು ಮಳೆಯೇ ..ಏನು ನಿನ್ನ ಹನಿಗಳ ಲೀಲೆ
ಭುವಿ ಕೆನ್ನೆ ತುಂಬ , ಮುಗಿಲು ಸುರಿದ ಮುತ್ತಿನ ಗುರುತು..
ನನ್ನ ಎದೆಯ ತುಂಬ , ಅವಳು ಬಂದ ಹೆಜ್ಜೆಯ ಗುರುತು..
ಹೆಜ್ಜೆ ಗೆಜ್ಜೆಯಾ ಸವಿ ಸದ್ದು ಪ್ರೇಮನಾದವೂ...
ಎಡೆ ಮುಗಿಲಿನಲ್ಲಿ , ರಂಗು ಚೆಲ್ಲಿ ನಿ೦ತಳು ಅವಳು.. ಬರೆದು ಹೆಸರು ಕಾಮನಬಿಲ್ಲು , ಏನು ಮೋಡಿಯೋ...



ಮುಂಗಾರು ಮಳೆಯೇ ..ಏನು ನಿನ್ನ ಹನಿಗಳ ಲೀಲೆ
ಯಾವ ಹನಿಗಳಿಂದ , ಯಾವ ನೆಲವು ಹಸಿರಾಗುವುದೋ ಯಾರ ಸ್ಪರ್ಶದಿಂದಾ , ಯಾರ ಮನವು ಹಸಿವಗುವುದೋ ..
ಯಾರ ಉಸಿರಲಿ ಯಾರ ಹೆಸರೋ ಯಾರು ಬರೆದರೋ ಯಾವ ಪ್ರೀತಿ ಹೂವು ,
ಯಾರ ಹೃದಯದಲ್ಲಿ ಅರಳುವುದೋ ಯಾರ ಪ್ರೇಮ ಪೂಜೆಗೆ ಮುಡಿಪೋ , ಯಾರು ಬಲ್ಲರೂ



ಮುಂಗಾರು ಮಳೆಯೇ ..ಏನು ನಿನ್ನ ಹನಿಗಳ ಲೀಲೆ
ಒಲವ ಚಂದಮಾಮ ನಗುತ ಬಂದ ಮನದಂಗಳಕೆ ಪ್ರೀತಿ ಬೆಳಕಿನಲ್ಲಿ, ಹೃದಯ ಹೊರಟಿದೆ ಮೆರವಣಿಗೆ ಅವಳ ಪ್ರೇಮದೂರಿನಕದೆಗೆ, ಪ್ರೀತಿ ಪಯಣವೂ..
ಪ್ರಣಯ ದೂರಿನಲ್ಲಿ , ಕಳೆದು ಹೋಗೋ ಸುಖವ ಇಂದು ಧನ್ಯನಾದೆ ಪಡೆದುಕೊಂಡು ಹೊಸ ಜನ್ಮವೂ



ಮುಂಗಾರು ಮಳೆಯೇ ..ಏನು ನಿನ್ನ ಹನಿಗಳ ಲೀಲೆ...!!!

Life is a....

Life is a series of linear events. A chain of choices about those events, leading to other events. Never ending cycles of pain and pleasure for learning and growth.

When the sun shines, it shines on everyone. When it rains, it rains on all. Every single person will experience at some point during their lifetime: tragedy, failure, depression and hopelessness. They will also experience: joy, happiness, success and unconditional love. We live in a world of duality.

There is a reason for it .Some people master the rollercoaster ride life offers them, and some don't. Why? It is an easy question to answer. The successful ones believe in themselves and their ability to win. While the others feel overwhelmed by life's ambivalences. They do so because their fearful thoughts keep them frozen in indecision, unable to make progress, due to fear of failure. If they only knew that "they were not their thoughts" improvement would be certain.

The reasons for feeling negative about yourself are numerous. Growing up in a disfunctional family. The criticism of inexperienced teachers. Comparing yourself to, and competing with, others. Holding unrealistic expectations of performance and many more. The reasons don't matter, they're history. What matters is now. This present moment. What do you do now to change your life.

First. Realize that "you are not your thoughts." Your thoughts are under your control at all times. There are no exceptions to this. People do not make you angry; you allow yourself to become angry. People do not depress you; you depress yourself. Your emotions are controlled by you and you alone. Quit reacting to others in a knee-jerk fashion and start thinking.

Second. Get away from all the negative stuff you possible can. Don't watch or read the daily news. If something important happens, a friend will let you know. Don't go to negative movies, read negative books, etc. Stop eating and drinking things that have a negative effect on you -- booze, cigarettes, snuff, drugs, etc. Not easy, huh! Well, quit as many as you can now, the others will come later.

Third. Start working with positive things. Read self-help books, inspirational books, biographies of famous people, etc. Join a support group, make friends with positive people.

Whether you believe it or not -- you are eternal. Within you is a light and love so powerful, so beautiful, that it can not be described in human language. You can't fail. You will succeed. You are always safe and secure. Your Creator is proud of you and never loses faith in you. Don't lose faith in yourself.

Like One rain drop in deep ocean blue ..
A fleeting vapor from morning dew...
A whisper hushed by competing voices..
A haunting note in melodies sung...

Yes, we are part of a wonderous family
Yes, still defined by the power of One !

One tree can start a forest...
One flower can awaken the dream..
One song can spark a moment...
One bird can herald Spring.

One smile begins a friendship..
One laugh will conquer gloom..
One candle destroys the darkness..
One sunbeam lights a room.

One breath brings life eternal...
One path will lead you home.
One step must start each journey ...
One touch can show you care...

One hope will raise our spirits
One word must start each prayer...
One heart know what is true ...

One life can make the difference..

And that ONE is

YOU!

Your Time Is LIMITED!!!

“Your time is limited, so don’t waste it living someone else’s life. Don’t be trapped by dogma —which is living with the results of other people’s thinking. Don’t let the noise of other’s opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.”

“The best day of your life is the one on which you decide your life is your own. No apologies or excuses. No one to lean on, rely on, or blame. The gift is yours - it is an amazing journey - and you alone are responsible for the quality of it. This is the day your life really begins".

I come across these quote every once in a while...It reminds myself to live from my own heart and my own mind every single day.

Thinking out of the box !!

It is January 1996..Larry and Sergey, Two Stanford computer science grad students, begin collaborating on a pathbreaking innovative idea of a search engine called BackRub.BackRub operates on Stanford servers for a year – eventually taking up too much bandwidth.


Just two years after Sun co-founder Andy Bechtolsheim writes a check for $100,000 to an entity that doesn’t exist yet – a company called Google Inc.And with that money Google sets up workspace in Susan Wojcicki’s garage at 232 Santa Margarita, Menlo Park.

It's now just 13 years later, Google Inc has just grown up from a small office in garage to skyscrapers with Multi-Billion dollar Business spanning accorss almost all part of the world.Proving Google as the closest thing to an Omniscient (all-knowing) entity in existence....Because google search engine knows everything!!and every one knows Google!!! :-)



In 1934,Bill Hewlett and Dave Packard electrical engineers from Stanford University go on a two-week camping and fishing trip in the Colorado mountains during which they become close friends. Bill continues graduate studies at MIT and Stanford while Dave takes a job with General Electric.

With the encouragement of Stanford professor and mentor Fred Terman, the two decide to start a business "and make a run for it" themselves. Bill and Dave formalize their partnership January 1, 1939. They decide the company's name with a coin toss.

As their first venture Bill and Dave begin part-time work in rented garage with $538 in working capital..Now,This shed has grown up to a most renowned Business in the world with the name of
Hewlett-Packard.

It's true!...Another exhilarating achievement story about a startup grown from a garage to epiccenter of innovative thinking..its all started with a College Dropout who couldn't see the value in formal college education and had struggled a lot during his initial days without having any place to sleep and proper food to eat. He didn't have a dorm room, so he slept on the floor in friends' rooms .He used to walk the 7 miles across town every Sunday night to get one good meal a week at the Hare Krishna temple.

In 1976,When he was just 20 started a company with the help of his friend in his parents garage .they worked hard, and in 10 years Apple had grown from just the two of them in a garage into a $2 billion company with over 4000 employees.

The first few years or so things went well. But then steve and his board of directors visions of the future began to diverge and eventually they fired Steve jobs from his own company.

True!!...An optimist is one who makes opportunities of his difficulties.After being fired fromApple, Without losing heart He Discovered a little animation company that needed a vision.Liked the product so much he bought the company and named it as Pixar Animation Studios, which has created eight of the most successful and beloved animated films of all time: Toy Story, A Bug's Life, Toy Story 2, Monsters, Inc., Finding Nemo, The Incredibles, Cars and Ratatouille. Pixar has won 20 Academy Awards and its films have grossed more than $4 billion at the worldwide box office to date.

In the meantime, without steve jobs Apple Inc became just like a body without soul . In1996 Apple reinstated Jobs as the Chief Executive Officer .Later he helped to grow Apple from a company bordering on bankruptcy in the 1990s to a very successful company today . Now ,Apple leads the industry in innovation with revolutionary and truely amazing products like iPod and iPhones.


When i was a kid ...i was so keen to watch SachinTendulakr playing cricket match against pakistan .Still i remember about his debut match when he was just 16 , It was common belief those days that a young boy like sachin won't be able to keep the nerve against the piercing pakistan bowling attack for too long . But, defying all our beliefs Sachin destroyed the much feared Pakistan bowling attack and clearly showed his authority of a class batsman .I was not sure what was going through his mind at that point of time. but, it resulted in Paradigm shift in peoples thinking about the way we look at game of cricket.

There are thousand examples like above we can find in our real life.These people are no different from us.They are not "chosen one" .But,They themselves chosen to be different from others. These people think differently, unconventionally with a new perspective much different from set of beliefs we follow. They invent. They imagine. They heal.They explore. They create. They inspire.They push the human race forward And They change the way we see our world forever!! :-)

63 Years Young and Still Rockin....

What are we waiting for?..Get started now !.

“Don't wait until everything is just right. It will never be perfect. There will always be challenges, obstacles and less than perfect conditions. So what. Get started now. With each step you take, you will grow stronger and stronger, more and more skilled, more and more self-confident and more and more successful.”

We pay a heavy price for our fear of failure. It is a powerful obstacle to growth. It assures the progressive narrowing of the personality and prevents exploration and experimentation. There is no learning without some difficulty and fumbling. If you want to keep on learning, you must keep on risking failure all your life.

DHCP - DORA Process Explained

When you connect a computer in a network , automatically you will get an ip address for your computer or when you try with ipconfig/release and Ipconfig/renew from your DOS prompt in your system you will get a new ip address.But what exactly happens at the packet level ..here is an attempt to explain this in detail with the Help of Wireshark packet capture .

1) Discover:
Client makes a UDP Broadcast to the server about the DHCP discovery. Asit doesn't know where the DHCP server is reachable in the network it sends UDP broadcast with the source ip address as 0.0.0.0 and destination ip address as 255.255.255.255 with its own MAC address .Unless, we have a DHCP Relay agent in the same subnet, IP helper address, etc. configured on your router. Then the broadcast is forwarded to a specific destination.
2)Offer:

DHCP Server offers to the client with available ip address,lease time sunbnetmask,gateway and DNS information .communication will be established based on the mac-address of client.
3) Request:

In response to the offer Client requests the server . Note that still client is not having the ip address. Now client makes request to the server for the IP information being offerd by the DHCP server .
A client can receive DHCP offers from multiple servers, but it will accept only one DHCP offer and broadcast a DHCP request message. Based on Transaction ID field in the request, servers are informed whose offer the client has accepted. When other DHCP servers receive this message, they withdraw any offers that they might have made to the client and return the offered address to the pool of available addresses.
4)Acknowledge:
Server responds all the Ip Add/mask/gateway/dns/wins info along with the acknowledgement packet.
Last but not least, if none of the DHCP server is availble in your network or the connection is broken to your DHCP server APIPA would automatically assign a unique class B IP address to each machine in the range of 169.254.x.x range.
For more information on DHCP please reffer RFC 2131 .

RFC 2616-Hypertext Transfer Protocl HTTP 1.1

Hi All , This article is an attempt to explain commonly used protocols in much simple way . Let's start with the most familiar protocol widely used by Netizens while browsing.... that is Http .

Here we go !!...

When you open a browser like IE or Mozilla Firefox , in the address bar you type in http://www.anywebsite.com/ and you will get all the conetnts of the webpage ,but what excactly happens in the background ?...let me try to explain in detail . Setting aside the DNS resolution and the way TCP 3 way handshake takes palce and the way a transport layer virtual circuit established between two programs for the purpose of communication Here we focusing on the way Http works .

The Hypertext Transfer Protocol (HTTP) is an application-level protocol for distributed, collaborative, hypermedia information systems.

The HTTP protocol is a request/response protocol. A client sends a request to the server in the form of a requestmethod, Uniform Resource Identifier (URI)-A network data object or service that can be identified by a URI and protocol version, followed by a MIME-like message containing request modifiers, clientinformation, and possible body content over a connection with a server.

Packet Capture 1:

your browser is asking for the page called "http.html". It wants to use the http1.1 protocol. Your browser is in English-US and is Microsoft Internet Explorer 6.0 under WNT 5.1.Your browser wants the connection (socket) stays opened between you and the destination web server it can ask for further files, like pictures included in this page...

Packet Capture 2:

In response to this , the web server knows the page you want and can send it : code 200 means its all OK!! Then, you have some more infos about the server : Apache on Unix, socket closed after html page, last modification date and so on (see attributs page for more information). And finally, the requested file...And Boom!!..you will get the requested webpage on your screen .

Lets look in to whar Http codes and Http headers are composed of :

In Http Header A first line containing the request statuts.Example : HTTP/1.1 200 OK
1 few line contining some attributes on the request.Example : Content-Type: text/htmlHttp codes sent by the server gives the status on the current http request.Theses codes are

normalized : Informational, request received, continuing process .

Here are some components in the packet capture detailed ;

The GET method means retrieve whatever information (in the form of an entity) is identified by the Request-URI.If the Request-URI refers to a data-producing process, it is theproduced data which shall be returned as the entityin the response and not the source text of the process, unless that text happens to be the output of the process.

The Referer request-header field allows the client to specify, for the server’s benefit, the address (URI) of the resource from which the Request-URI was obtained.

The Accept request-header field can be used to specify certain media types which are acceptable for the response.Accept headers can be used to indicate that the request is specifically limited to a small set of desired types, as inthe case of a request for an in-line image.The asterisk “*” character is used to group media types into ranges, with “*/*” indicating all media types and“type/*” indicating all subtypes of that type. The media-range MAY include media type parameters that areapplicable to that range.

In a nutshell ;

HTTP uses the client-server model: An HTTP client opens a connection and sends a request message to an HTTP server; the server then returns a response message.

The initial request line is different for the request than for the response. A request line has three parts, separated by spaces: a method name, the local path of the requested resource, and the version of HTTP being used.

A typical request line is:
GET /path/to/file/index.html HTTP/1.0

GET is the most common HTTP method; it says "get me this resource".

Other methods include POST and HEAD.

The HEAD Method HEAD request is just like a GET request, except it asks the server to return the response headers only, and not the actual resource (i.e. no message body). This is useful to check characteristics of a resource without actually downloading it, thus saving bandwidth. Use HEAD when you don't actually need a file's contents.

The response to a HEAD request must never contain a message body, just the status line and headers. A POST request is used to send data to the server to be processed in some way, like by a CGI script.

The path is the part of the URL after the host name, also called the request URI (a URI is like a URL, but more general). The HTTP version always takes the form "HTTP/x.x", uppercase.

Response Line (Status Line)

The initial response line, called the status line, also has three parts separated by spaces: the HTTP version, a response status code that gives the result of the request, and an English reason phrase describing the status code. Typical status lines are:
HTTP/1.0 200 OK
or
HTTP/1.0 404 Not Found
The most common status codes are:

200 OK The request succeeded, and the resulting resource (e.g. file or script output) is returned in the message body.

404 Not Found The requested resource doesn't exist.

301 Moved Permanently

302 Moved Temporarily

303 See Other (HTTP 1.1 only) The resource has moved to another URL (given by the Location: response header), and should be automatically retrieved by the client. This is often used by a CGI script to redirect the browser to an existing file.

500 Server Error An unexpected server error. The most common cause is a server-side
script that has bad syntax, fails, or otherwise can't run correctlyfor HTTP 1.0, and section 10 for HTTP 1.1

How HTTPS works ?

In this section only let me try to describe how the HTTPS communication takes place; Again this is request/protocol . imagaine that you are trying to browse a secure website like https ://anywebsite.com and following process needs to be passed in background ;

1.As we know any browser Like IE 7 or Mozilla firefox will come with the severa l CA issuer certificates .And these certificates will have the Public key for the issuer of the cerfticiate and other information . Its a key used to encrypt the data so that only the reciever is having valid private key will bable to see it .

When anyone wants to use SSL , he needs to purchase a certificate thats signed using the CA's Private key .

2. Once the web browser starts the connection to the secured site allong with the request and other information it will send all supported encryption schemes.

3. The webserver will response the browser client information with the copy of the certificate that is signed using the CA's Private key and information about supported encryption schemes .

4. Once the certificate is downloaded to the browser client , it will be tested against the CA's public key installed on the Web browser ..if everything seems to be okay..then connection will be establiched and data will be downloaded using the secure encryption scheme earier negotiated while SSL handshake .

Let me try explaining the same with the following packet capture ; In this following example connection fails as browser recieves the certificate from server and its tested against the Public key installed in browser and connection won't establish because it turns out be a Bad certificate .

Michael Phelps - SuperHuman in Action

As I'm sure you already know, on Sunday August 17th 2008, Michael Phelps achieved one of the greatest sporting records of all time by winning an incredible 8 gold medals in a single Olympic games.




Michael's performance was seen by millions of people around the world and we can all learn a great deal about achieving our own goals by analyzing his accomplishment. Here then, are five secrets of success that helped Michael Phelps to transform his dreams into reality.

Secret #1: Think BIG


The first step in Michael Phelps journey was to make the decision to pursue a dream that many people considered impossible. Instead of thinking negative thoughts and limiting his potential, Michael allowed himself to think big.

"If you dream as big as you can dream,
anything is possible."
- Michael Phelps


Your Turn:

In order to discover your real goals, let your imagination run free to dream as big as you can dream. Resist the temptation to limit yourself with negative thoughts. It is only by freeing your imagination that you can discover what it is that you really want from life.

Secret #2: Break it Down

Having identified his ultimate goal, Michael and his coach created a series of short term goals that would eventually lead him to his ultimate objective. In between the Olympics came the National championships, the Pan Pacific championships and the World championships. Each race of each event was a carefully planned stepping stone that would eventually lead Michael to achieve his ultimate goal of becoming the most successful Olympian of all time.

Your Turn:

After identifying your long term goal, take some time to break it down into a series of achievable short term goals. As you move forward, focus on achieving your short term goals one step at a time.

Secret #3: Use the Power of Visualization

One of the most powerful techniques used by elite athletes to achieve their goals is to visualize themselves succeeding each and every day. In his book 'Beneath the Surface', Michael Phelps writes, "When I'm about to fall asleep, I visualize to the point that I know exactly what I want to do: dive, glide, stroke, flip, reach the wall, hit the split time to the hundredth, then swim back again for as many times as I need to finish the race".

Your Turn:

Visualizing your goals before you sleep is a great way to program your subconscious mind. The more you visualize your dreams as a reality, the more motivated and determined you will become.

Secret #4: Put in the Hard Work

No matter how naturally talented Michael Phelps may be, the main reason he achieved his goals was because he was prepared to put in the thousands of hours of grueling hard work necessary to compete at the highest level. According to Michael, "In the four years between the Athens and Sydney Olympics I probably took four or five days off and none of those were holidays"


Your Turn:

Be prepared to put in the hard work required to transform your dreams into reality. There really is no such thing as getting something for nothing. In order to make your dreams a reality you will have to work hard.

Secret #5: Monitor Your Performance Metrics

Every elite athlete understands the importance of using metrics to monitor their performance and progress. Michael's coach Bob Bowman constantly monitors and reviews Michael's split times down to the hundredth of a second. This provides them both with tangible evidence of how Michael is progressing towards achieving his goals.

Your Turn:

As you work towards your goals, figure out your own key metrics. For example, if you are studying, record how many hours of productive work you do each day. Or if you are building a business, record how many potential customers you contact each week. Whatever your goal may be, you will get there faster by recording and constantly improving your performance metrics.

While you may not be pursuing an Olympic gold medal, always remember that your life goals are just as important. I’d like to encourage you today to use some of the same techniques Michael Phelps used to achieve his goals. If you can

(1) Think BIG
(2) Break it down
(3) Utilize the power of visualization
(4) Work hard and
(5) Monitor your performance metrics

you too can conquer the challenges that stand in your way and make your dreams a reality.

Until Next Time,

Dare To Dream!
