Alla Rakha Rehman, proved what you can achieve when you control your emotions and make them secondary, this guy does what he believes is the truth of life and he controls his emotions thinking its just another day in this materialistic world and he submits all his so called victories to feet of the lord.
Controling emotions and devoting yourself to what you believe can get to the heights like. Great legends have done that and rehman is an living example, check out how much controlled he is during the best moment of his life, A thing that we all should as a human being learn from him.

World's first personal supercomputer launched
A desktop supercomputer talk of past is a reality now. nVidia US based company has successfully developed and is getting ready to launch Tesla. It has been priced between 4000-8000 pounds/ $10,000.
The Tesla built on compute unified device architecture (CUDA) would not replace the CPU (central processing unit) of a personal computer, but it would complement the work of the CPU with the help of GPU numerous times.
It is said to be 25 times faster than normal PCs.The scientists claim that Tesla will completely revolutionize the way researchers and medical professionals carry out their work. For example, doctors would be able to examine the result of brain and body scans in much more less time and inform patients within hours whether they are suffering from a tumour.
Microsoft tech, Bruton says, Heterogeneous computing, where GPUs work in tandem with CPUs, is what makes such a breakthrough possible. It is said that Tesla has also reached record setting performance.
Computer makers such as Dell, Lenovo, and Hewlett-Packard came forward to power their desktops and laptops by Tesla.
On the long run for a fast paced world, this is no doubt going to be the NExtGen computer to invade every home.

Mozilla Firefox
There are various browsers available in the market of software. The intelligence lies in which browser is to be used under what circumstances.
One of the browsers adorable is Mozilla Firefox.Though Mozilla installs small, efficient products, it is build on a very large open source that supports a complex and flexible structure underneath as a SQL db server with Linux kernel or J2EE. Use of XUL instead of simply HTML-applications also called LAMP X, allows Mozilla to overcome all UI mess in terms of navigation, layout and performance.The Mozilla platform and applications can be sliced a number of ways so that the balance between client and server is determined by people, not dictated by the technology.
1. Can add multiple home pages on launch of browser.i.ie by inserting "|" in the default bookmark without quotation.
2. debug scripts using programming
3. Few key commands to work faster
-- Ctrl- and Ctrl+ can be used to zoom in and out
-- Ctrl+t new tab
-- Ctrl+k to move cursor to the search box
-- Ctrl+w close window
-- Ctrl+F3 search
-- find text as u type using /
-- back and forward alt+<-- alt+-->
-- Ctrl+ and Ctrl- change font size
-- Ctrl+l to move to the location bar
-- switch between tabs ctrl+tab
and lots more of them...
4. can add-ons to get working more colorful and fast.
5. Add ons supporting different themes and templates, mail notifications, cross platform ftp support and many more.(something similar to winscp)
6. customise browser using monkeygrease and greasemonkey.
7. seesion restore oncrash
There must be many more stuff available.On the whole its cool to work on such applications knowing their potential rather blindly using them.

Walks of Life !!!
A human being comes to this world, lives and finally leaves the world. When I say this word I remember the words of shakespeare "Men may come and Men may go but the stage remains the same." When we look the life cycle of a human being, he takes different roles at different stages of life. to begin with he is a sweet child with no tooth,everybody likes to play with him,they take utmost care of him. When he grows up he gets on to school where he mingles with a lot of people of his age and starts learning new things and when he moves into the adolescent age, he feels something unsual within himself, falls in love with almost all gals he sees, tries to do all wrong things in his life. feels old people are there in this world only to give advice, thinks he is the boss and knows how to live his life. He gets into the college and feels like in heaven. he knows no fear and no boundaries, enjoys life to the core.
Out of college things change, he gets to know the situation of his life and get to know what life is and what people are, how people behave and what status they give for a person and how and when. He gets into the phase of realizing his dreams, works hard and gets a life which suits his lifestyle and tries to make up his own family.
Once he has somebody with him he again starts running to make his and his dependant life better. He tries to enjoy life but could not. He becomes a father which he would always be proud of, tries to give the best to his children, wants his children to get everything which he didnt get.
Things fly by he becomes old and becomes a grandfather and tries to rewind his life with his old memories only to find that he has not lived the way he wanted.
Roles that a person plays in different walks of life are
1. baby
2. Kid
3. School boy
4. Teenager
5.College Student
6. Professional
7.Lover
8.Husband
9.Boss
10. Father
11. A responsible person in the society
12. Grandfather
13. A human being who leaves this world without knowing the truth of life
Well this is the normal life cycle of a human being, but how many of us think beyond this, how many of us think that there is a reason for our existence. how many of us think that there is reason behind every action in our life. how many of us think about the lessons that has been taught to us in the walk of life. How many of us tend to follow the rules of the game.
Life is something which is not to be lived anyway we wanted, it is to be lived the way it is supposed to be.
I dont want to confuse more than this. Just think about it. !!!!

Life as such
Life this four letter word is the prime factor of existence of any living being that is known to exists in this world, In simple terms life just means breathing, pumping in Oxygen and pumping out CO2, well one of the definition of life is the experience of being alive.
Whole of the human race is driven by money,fame,satisfaction,spirituality,greediness,hatred,love,affection,cruelty and lot more and any one of these characteristics is adpoted by an individual inorder for him to lead a better life. Lot of people are of the illusion that they are having a great life, a better life without knowing the fact that they dont know what life is but they think that they have a better life.
Each and every living being wants to have a happy and peaceful life, but how does one know what life is or how does one say that they are having a happy and peaceful life, If suppose a person is happy if people appreciate him, does it mean that he wil lead a happy life if people keep on appreaciating him. In this case does it mean that life is nothing but sheer satisfaction of the heart or is it the mind which makes a man lead a peaceful life, If a man does not have any tension does it mean that he is having a peaceful life.
No matter whether your happy,sad,in peace. Life remains static and is a straight line, its only the emotions that travels over this line of life that decides the mood or state of an individual. If you come out of your emotions and feelings and look at life, life is nothing but a straight line.

Kill and Zero
kill is a command used to send simple messages to processes running on the system. By default, the message sent is the "termination" signal, which requests that the process exit. But kill is something of a misnomer; the signal sent may have nothing to do with process killing. The kill command is a wrapper around the kill()system call, which sends signals to processes or process groups on the systemWe all know about kill command and how much we use it especially kill -9 the forceful exit of a process.
The kill command associates itself with options ranging from (0-9). But the most fascinating one is 0 the number close to India. Remember (Aryabhata is the first of the great astronomers of the classical age of India who invented "0").
The interesting part is kill -0 actually does not kill a process. The kill -0 option can be used to
figure out whether a particular process id exists. It never sends a signal.
This option can be used in logics where programmer wants to know how long a process exists and if any action is to be taken based on its usage.
Assuming the command is called after certain duration of sleep, the command gets executed and remains silent until it gets to know the process is terminated. And would return an output like "-bash: kill: (8141) - No such process".
Wonders of zero are unlimited !!!
Features of Google Chrome
Its been close to a week since Google announced its first browser called Chrome. One of the prime goals of the development team of Google chrome was to minimize or remove the chrome from the browser and this is what the development team as actually done.
The browser is simple and loads pretty quickly, the setup file (which I got after a long wait) is of 475 KB and it installs just like Ubuntu a quicky OS which I have loved always. The browser design is simple viz a viz Google, it looks transparent to the desktop and its thin background makes it look light. It has no menu bar like the traditional browsers.
Some of the key features of Chrome
1. There is no homepage as such in Chrome. However the homepage is where 8 recently visited sites are shown as site snippets .
2. It has integrated google search in the address bar, so you start typing "Y" in the address bar and it start suggesting you the websites
3. It also has the google calculator integrated in the address bar, so want to make any calculations,type it in the address bar.
4. In chrome every tab acts as a process and all the plugins act as process and there is a inbuilt exclusive task manager where you can have a look at the different process(tabs viz a viz website) and the memory they are occupying at any given time
5. Chrome as the same feature like the IGoogle where you can move the gadgets around the IGoogle, similarly just move a tab out of the browser and it opens as a new window and when u pull this window back into the main window it becomes a tab again.
6. In chrome the default search in the address bar is Google search, you can also choose, Live, Yahoo search , AOL , Ask by right clicking on the address bar and choosing the edit search engine
7. Its open source, so the code is given to you for you to tweak
8. Downloading option is good, it directly starts the downloading and the file stays at the bottom of the browser and once the download is complete you can drag and drop it in any place you want.
9. You want security, its google so it has it , its called inconginitive window ( more like the inPrivate in IE 8) where you browse anything , it leaves no trace of browsing.
10. For developers or beginners, it has a inbuilt html text viewer, so no more boring notepad to view the source of the html page, infact the text viewer highlights the syntax and it is more user friendly, parses each and every aspect of the webpage and categorises the same.
Built on V8 and webkit this browser is one of the trend setter for the modern web based applications, Two years of hard work from the Google engineers is ought to pay back.
Have a nice time with the new baby of Google !!!!!!!!!!!!

Google bangs again with Google Chrome with a cartoon
It was just the news of IE8 and Mozilla enhancing itself, the all time challenger Google swings back with a suprise launch of its new browser Chrome adding onto its growing application list.
Its an open source browser,which supports Javascript VM called V8 (That can be used by other browsers too to enhance the speed of web browsing) with a Webkit engine (supported in Safari), multi process design, special tab support,address bar with auto complete mode,default home page with speed dial feature as a default page(which will summarize recent searches,webpages visited and so on). The "InPrivate" feature of Microsoft is provided as "incognito" here.(enable /disable privacy) and finally constant download of lists of harmful sites...
The search giant said Chrome had been created to better handle interactive applications and resource-hungry web pages such as video clips and online games. It is also less likely to crash,
Indeed Google proves itself again and again...The browser seems to become the master of all browsers very much close to the user. The Chrome comic is not a joke.
Google simply makes others go "Googly Goooooooooo"

IE 8.0 Beta2 is on !!!
Microsoft announced the release of Internet Explorer 8 Beta2. Its more of a combination of features of Safari and Firefox, Some of the features which the beta version has is the Inpage search which is more like the safari inpage search. The new explorer has a DOM inspector, a JavaScript profiler, a color picker and ruler, options to outline objects, disable CSS and validate web pages. The New IE is developed on the new standards of the world wide web.
The new IE concentrates on AJAX enhancements,CSS and Support for data URI and one more feature that is added in IE 8 is that we dont need to view the source of the same old notepad software where the syntax are not highlighted, however the new browser has a inliner editor which displays the HTML source code with all the highlights of syntax.
Interms of security where Micorosoft always has a concern the browsing history,cookies,form data,usernam,password can be made not to be stored in the browser, It also blocks adult sites this feature is called Inprivate Browsing This can be set by navigating to Safety -> InPrivate browsing.
Finally Google maps and Gmail works fine in IE,
I'm sure lot of people will start using IE more often now, more of open source features is really drawing people to use IE, All the best to the microsoft team and hope to see IE 8 to be another successful product from Microsoft.

Monkeygrease says now Java's cool too
We have all heard of Greasemonkey but what s Monkeygrease now...(something still evolving not enrolled in wiki).Well Monkeygrease is a proxy-based server-side solution. That means a servlet filter that will allow a web developer to inject JavaScript, CSSor other elements within a web page. It will enable you to move your web application to the Web 2.0 world.
How do we get this working...
1. You must have Apache Tomcat 5.x. A web application whose WEB-INF directory is accessible.
2. You can download monkeygrease from here (This will include the jars, monkeygrease.xml file containing rules)
3. Installation
4. Restart your app server in order to enable the filter.
5. Output of a simple html file before and after can be seen as illustrated in view-example
Monkeygrease helps in:
- Changing the look and feel of a web application
- Adding DHTML/AJAX features/effects on your site
- Adding WYSIWYG editing to any textarea field on your site
- Enhance pages by contextually adding content from external providers
- Fix usability issues on any page
How do we get this working...
1. You must have Apache Tomcat 5.x. A web application whose WEB-INF directory is accessible.
2. You can download monkeygrease from here (This will include the jars, monkeygrease.xml file containing rules)
3. Installation
- 1.Extract the monkeygrease_xxx.zip file you downloaded
- 2.Upload the monkeygrease.jar file to your web application’s WEB-INF/lib directory. Depending on your application server, you might be able to do this through an administration console, however, if you have access to the web application’s directory, it’s probably easier to do it manually.
- 3.Upload the monkeygrease.xml file to your web application’s WEB-INF directory.
- 4.Modify your web application’s web.xml file and add the following lines that define rules. Click here to take the snippet of code. mentioned under point 4 in the linked page.
4. Restart your app server in order to enable the filter.
5. Output of a simple html file before and after can be seen as illustrated in view-example
Hope this start will take Monkeygrease much further...

Oracle Tip
There are lot of interesting stuffs that can be done using the data dictionary tables in oracle. There are lot of data dictionary available in oracle. Some of them are
user_tables,
user_tab_cols
user_views
The different data dictionaries that are available in oracle can be viewed by querying ALL_VIEWS
select * from all_views ;
Now one of the data dictionary or one of the most powerful and useful one in oracle is dba_users. This data dictionary gives you the details about the database users that are available for a particular database. Now if suppose you want to access the database using a specific userid and you dont have the password of the user,however have the privilige to do things in the database then you can try to use the following stuff
SQL > select username,password from dba_users where username = 'SCOTT'
USERNAME PASSWORD
---------------------------
SCOTT F894844C34402B677
now alter the user to specify your custom password
SQL > Alter user scott identified by mypassword
Then login to the user scott using the password specified by you now and start working.
Once you have done with the work restore the old password by using the undocumented thing called by value
SQL> Alter user scott identified by values ' F894844C34402B677'
So that the password is restored to its originial value.
Hope the tip is helpful in certain aspects for the database administrators or it might be a way to provide an insight to the ways security breaches can be made if priviliges are available for database users.
SQL> select username,password from dba_users where username='SCOTT';
USERNAME PASSWORD

SQL > select username,password from dba_users where username = 'SCOTT'
USERNAME PASSWORD
---------------------------
SCOTT F894844C34402B677
now alter the user to specify your custom password
SQL > Alter user scott identified by mypassword
Then login to the user scott using the password specified by you now and start working.
Once you have done with the work restore the old password by using the undocumented thing called by value
SQL> Alter user scott identified by values ' F894844C34402B677'
So that the password is restored to its originial value.
Hope the tip is helpful in certain aspects for the database administrators or it might be a way to provide an insight to the ways security breaches can be made if priviliges are available for database users.
SQL> select username,password from dba_users where username='SCOTT';
USERNAME PASSWORD
-------- ----------------

Greasemonkey !!!
FireFox - Greasemonkey
Greasmonkey is a firefox extension that allows you to write scripts that alter the webpages you visit
Some of the things which we can make using Greasemonkey is :
1. Make websites more readable.
2. Fix rendering bugs which the owner is not aware of.
3. Alter pages to make them work with other technologies like the speech based.
4. Retrieve data from multiple site and make them interconnected.
How to use Greasemonkey ??
To Use Greasemonkey, You need to install the Greasemonkey add-on unto yout Firefox browser and then we have to install the user script by choosing from the Tools > Install user script. The Greasemonkey is just an add-on and doesnt make any difference until the user scripts are installed. A repository of user scripts available. A user script usually ends with .user.js.
Let see how to use a sample greasemonkey script. As usuall its the Hello World script.
Example
The user script is named as helloworld.user.js
// Hello World! example user script
// version 0.1 BETA!
// 2005−04−22
// Copyright (c) 2005, Mark Pilgrim

//
// This is a Greasemonkey user script.
//
// To install, you need Greasemonkey: http://greasemonkey.mozdev.org/
// Then restart Firefox and revisit this script.
// Under Tools, there will be a new menu item to "Install User Script".
// Accept the default configuration and install.
//
// To uninstall, go to Tools/Manage User Scripts,
// select "Hello World", and click Uninstall.
//
// −−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−
//
// ==UserScript==
// @name Hello World
// @namespace http://diveintogreasemonkey.org/download/
// @description example script to alert "Hello world!" on every page
// @include *
// @exclude http://diveintogreasemonkey.org/*
// @exclude http://www.diveintogreasemonkey.org/*
// ==/UserScript==
alert('Hello world!');
As you read the script you might know what the script means, no install this script by using the install user script option and choosing helloworld.user.js
Once installed, whenever you move to a new page an alert will be made saying Hello World.
Greasemonkey can change the way you browse once installed and used. Hope you have got a insight on what greasemonkey is all about.
Happy browsing and cheers to Greasemonkey !!!

Gmail Temporary Error (502)
It seems that Gmail account was down for a part of users and they get the following error when trying to login.
"We're sorry, but your Gmail account is currently experiencing errors. You won't be able to use your account while these errors last, but don't worry, your account data and messages are safe. Our engineers are working to resolve this issue. Please try accessing your account again in a few minutes."

Last time such incident with respect to down of Google services were reported in the year 2004, Is the clustering effect having some bad time at Google. Google engineers seem to be working on the problem and reports say that they have narrowed down to the problem which is actually causing this 502 error. Google has confirmed that it will soon resume the services to the users as it has come up with a fix and will kill out the error in sometime.
The Service was down for more than an hour for the users.
Have you come across any errors like these when accessing any of the Google services ???. post in your comments

What's Happyness ???
Well how many of us have asked this question to ourselves and what is the answer have we got for this. Let me quote one by one1. Is getting a 1st rank in school fetches happyness to a kid - well then is all 1st rank holders happy (answer is only when they got it and not always)
2. Is getting a riding a bicycle brings happyness to a kid (well when you ask all the kids who ride bicycle they are not happy always)
3. Is everyone who has a beautiful gal friend/boy friend happy(I dont think so :))
4. Is everyone whose child is working in abroad and well settled happy always (I've seen them only feel they could be with their children.
There are lot more examples that can be quoted and we have to agree to the point that there is no human in this world who can be happy always and never be sad, but the question I wanted to raise is , Is happiness associated with some object or thing or is it a feeling.
Is happiness momentary, Does the kid gets happy the moment he gets first rank or gets a bicycle and then his happyness vanishes or is smiling alone represent the sheer meaning of happyness
Therasus defines happyness as "state of well-being characterized by emotions ranging from contentment to intense joy"
But one way or the other I feel that inner happyness is what is permanent, inner happyness is achieved when there is a equilibrium between the external and the internal factors of the human body where mind plays a vital role, when you have a perfect balance between your inner self and the external ,your ought to enjoy happyness to the core, when you reach a state of mind where you are ready to receive both success and failure in the same frequency you are in a state of immortal happyness, this doesnt mean that we should not be aggressive in achieving our goals , but our perception of success and failure should not determine our happyness because success and failure are mutually exclusive,but happyness is not. Everybody says that we should learn from our mistakes when we fail, but we forget that we should also learn from the positive things of our success and use the same to move forward in achieving our goals. Again when you train your mind to get the balance between success and failure you will see the real happyness in your life that is unexplainable.
Be happy as always !!!!
