tamil new year

2008-04-11T14:09:01+02:00

TAMIL NEW YEAR

The month of Chitthirai has arrived and with it the Tamil New Year’s Day; April 14th – an occasion for celebration for Tamilians all over the world. Greetings of “Puthandu Vazthukal”, (Happy New Year), are exchanged with fervour on this day, which is supposedly the day when Lord Brahma (The Creator of the world, according to Hindu mythology) started creation.

Almanac for the year 2001-02The day starts with viewing the 'kanni' (the auspicious sight) at dawn, in the expectation that beginning the New Year by looking at auspicious or favourable things will bring good fortune throughout the year. The auspicious things include, gold and silver jewellery, betel leaves, nuts, fruits and vegetables, flowers, raw rice and coconuts. This is followed by the ritual bath and a visit to the temple to pray for a prosperous and happy New Year. After which, the Panchangam (almanac) is read. The ladies adorn the entrances of their houses with ‘Kolam’ (design made with rice flour) and deck the doorway with mango leaves. A grand Car Festival is held at Tiruvadamarudur near Kumbakonam every year on April 14th. Also during the month of Chitthirai the marriage of Goddess Meenakshi to Lord Sundareswarar is celebrated as ‘Chitthirai festival’.

The highlight of the festival is the 'Maanga Pachadi' (a dish made of raw mangoes, jaggery and neem flowers), which is at the same time sweet, sour and bitter. This signifies all the different aspects of our life.

April 14th also happens to be the Bengali New Year Day, Naba Barsha, which begins with the ‘Prabhat Pheries’ (an early morning procession) with songs and dances welcoming the New Year. In Kerala ‘Vishu’ is celebrated by Malayalees commemorating the beginning of the astronomical New Year in the Malayalam Calendar.

The Tamil Calendar, which has 12 months from Chitthirai (April - May) to Panguni (March - April), has a 60-year cycle.

Cellphones use greater threat than smoking

2008-04-01T11:43:13+02:00

Cellphones use greater threat than smoking;
A top Australian neurosurgeon of Indian origin says cell phones use is a greater threat to human health than smoking, which kills 5.4 million people each year.

Dr Vini Khurana, a neurosurgeon at the Canberra Hospital, told UK's Independent newspaper that there is growing evidence that using handsets for 10 years or more can double the risk of brain cancer. This, however, does not mean that smoking is better for health than using cellphones.

Dr Khurana says the cellphone threat is greater because far more people use cellphones than smoke worldwide, some of them starting use at the age of 3 years. Over 3 billion people use cellphones, which is three times higher than the one billion people who use tobacco.

In India, 250 million people use cellphones, second only after US's 256 million users. The threat came from cell phone radiation having the potential to heat the side of the head or thermo-electrically interact with the brain, while Bluetooth devices and unshielded headsets could convert the user's head into potentially self-harming antenna, said Dr Khurana.

He said there have been increased reports of brain tumours associated with heavy and prolonged mobile phone use, particularly on the same side as the person's "preferred" ear for making calls. Since cell phones were often a necessity, he says, people should use them as little as possible and called on the phone industry to make them safer.

The World Health Organisation says that cellphones are safe but admits there are "gaps in knowledge" that need further research about health impact in the longterm. Three large international reviews have investigated and found no conclusive link between use of cell phones and brain cancer, tumours of the brain or leukaemia, and other cancers.

DBMS

2008-03-16T07:59:41+01:00

DBMS
database management system-single,self-defing store of data,data independent of access programme,supports multiple view of data,supports sharing of data,supports moinatoring and control of data.
some software:
SQLstructured query language)
Abbreviation of structured query language, and pronounced either see-kwell or as separate letters. SQL is a standardized query language for requesting information from a database. The original version called SEQUEL (structured English query language) was designed by an IBM research center in 1974 and 1975. SQL was first introduced as a commercial database system in 1979 by Oracle Corporation.
Historically, SQL has been the favorite query language for database management systems running on minicomputers and mainframes. Increasingly, however, SQL is being supported by PC database systems because it supports distributed databases (databases that are spread out over several computer systems). This enables several users on a local-area network to access the same database simultaneously.
Although there are different dialects of SQL, it is nevertheless the closest thing to a standard query language that currently exists. In 1986, ANSI approved a rudimentary version of SQL as the official standard, but most versions of SQL since then have included many extensions to the ANSI standard. In 1991, ANSI updated the standard. The new standard is known as SAG SQL.
DB2:
Short for Database 2, a family of relational database products offered by IBM. DB2 provides an open database environment that runs on a wide variety of computing platforms. A DB2 database can grow from a small single-user application to a large multi-user system. Using SQL, users can obtain data simultaneously from DB2 and other databases. DB2 includes a range of application development and management tools.
RDBMS:
Short for relational database management system and pronounced as separate letters, a type of database management system (DBMS) that stores data in the form of related tables. Relational databases are powerful because they require few assumptions about how data is related or how it will be extracted from the database. As a result, the same database can be viewed in many different ways.
An important feature of relational systems is that a single database can be spread across several tables. This differs from flat-file databases, in which each database is self-contained in a single table.
Almost all full-scale database systems are RDBMS's. Small database systems, however, use other designs that provide less flexibility in posing queries.

PROTOCOL:
protocol is set of rules that enables the exchanges of information btwn
to computer ,whatever they run on diferenting operating system.
TCPTransmission Control Protocol)
TCP is one of the main protocols in TCP/IP networks. Whereas the IP protocol deals only with packets, TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and also guarantees that packets will be delivered in the same order in which they were sent.

HTTP: (HyperText Transfer Protocol)
HTTP defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands. For example, when you enter a URL in your browser, this actually sends an HTTP command to the Web server directing it to fetch and transmit the requested Web page.

The other main standard that controls how the World Wide Web works is HTML, which covers how Web pages are formatted and displayed.

HTTP is called a stateless protocol because each command is executed independently, without any knowledge of the commands that came before it. This is the main reason that it is difficult to implement Web sites that react intelligently to user input. This shortcoming of HTTP is being addressed in a number of new technologies, including ActiveX, Java, JavaScript and cookies.
FTPFile Transfer Protocol,)
FTP is the protocol for exchanging files over the Internet. FTP works in the same way as HTTP for transferring Web pages from a server to a user's browser and SMTP for transferring electronic mail across the Internet in that, like these technologies, FTP uses the Internet's TCP/IP protocols to enable data transfer.
FTP is most commonly used to download a file from a server using the Internet or to upload a file to a server (e.g., uploading a Web page file to a server).
SMTP Simple Mail Transfer Protocol)
SMTP is a protocol for sending e-mail messages between servers. Most e-mail systems that send mail over the Internet use SMTP to send messages from one server to another; the messages can then be retrieved with an e-mail client using either POP or IMAP. In addition, SMTP is generally used to send messages from a mail client to a mail server. This is why you need to specify both the POP or IMAP server and the SMTP server when you configure your e-mail application.
ETHERNET:
A local-area network (LAN) architecture developed by Xerox Corporation in cooperation with DEC and Intel in 1976. Ethernet uses a bus or star topology and supports data transfer rates of 10 Mbps. The Ethernet specification served as the basis for the IEEE 802.3 standard, which specifies the physical and lower software layers. Ethernet uses the CSMA/CD access method to handle simultaneous demands. It is one of the most widely implemented LAN standards.

A newer version of Ethernet, called 100Base-T (or Fast Ethernet), supports data transfer rates of 100 Mbps. And the newest version, Gigabit Ethernet supports data rates of 1 gigabit (1,000 megabits) per second.

A Cellular Generation
There is no escaping them. They are everywhere such as in the stores, at the movies, in restaurants, in church, even in the classroom. And just what is this causing the constant buzzing in your ears and the persistent ringing in your head? Teenagers with cell phones! It seems that everywhere you turn there is a giggling, gasping, gossiping girl or a babbling, bellowing, blaspheming boy chattering away at a buzzing, ringing, palm-sized piece of plastic. In a national study by Teenage Research Unlimited, it was reported that nearly six million teenagers own a cell phone today (Lee,“Tailoring Cell Phones for Teen,” par. 7). Where has this craze come from? Why the obsession over wireless phones? While cell phones cater to the modern teen’s addiction to instant gratification, the “need-to-know-NOW” syndrome, they also serve as a mark of status, maybe a representation of maturity and certainly as source of comfort to an insecure and developing teenager.

Before cell phones were the hip thing it was pagers. And before that, it was little electric diaries with which you could beam messages to your friend sitting on the other side of the classroom. If you were really cool, you had one with voice recognition that

. . .
America has become almost dependent upon them. Such things have given teens raised expectations of speedy service. ” In many ways the cell phone has taken the place of God in some people’s lives. ] For the fact is that all idols appear to work – at first.

While thirty-three percent of teens own cell phones now (“Have Cell Phones Changed Society?”, sec. In adherence to the popular trend of individuality (catch the irony?) teenagers want more colorful and interesting cell phone options such as ring tones, face covers, logos, games, emails and text messaging. Webster’s Dictionary defines an idol as “that on which the affections are strongly (often excessively) set; an object of passionate devotion; a person or thing greatly loved or adored. These choices allow them to personalize their precious communication devices. It means people care about them and love them. Who has more messages,

which is liked more? Many times teens will leave their phones on at inappropriate times and in inappropriate places, such as class or the movie theater, hoping that it will ring and others will see that they are popular.

A History of Linux

2008-03-15T16:01:09+01:00

A History of Linux
A young college student named Linus Torvalds started Linux in 1991. He started this as a hobby based on Minix, a small version of Unix. His goal was to expand on the abilities of Minix and allow for a system that exceeded its capabilities. In 1991 he released version 0.2, the first version of the Linux kernel. He continued work on his project steadily until the release of version

. . .
4 and it continues to be updated every day. The beanbag of joy we now know as TUX was created and sat representing Linux in his own unique way. The penguin was to be sitting because he felt that had it just gorged itself the penguin wouldn’t want to be standing, it would want to sit down and relax. This was decided because it is his favorite animal. He also felt that it should look like it is slightly overweight so that it looks as if it had just gorged itself on herring. He felt that the penguin should look very content, not angry or ferocious, or even overly happy, just content. It was decided by Linus Torvalds that the mascot would be a penguin. Linus went through each of these and did not see anything that represented the operating system well. As of January 2001 Linux had reached version 2. After many letters from Linus to numerous people the logo was designed to his specifications. During the contest many people entered their versions of what it should look like.

Hacking, Cracking, Phreaking
The American Heritage Dictionary defines it as: To work as a hacker. We hear about it a lot but many's understanding of it is very vague. Hacking, its been around for more then a century and has caused many problems for people. Many are frightened by the word but for good reasons. Hacking is just a general term. There are many subdivisions to it but today I am going to talk about three primary divisions: Hacking, Phreaking, and Cracking. What do these divisions consist of you might ask? Well that is what I am here to tell you. I will give you a short history on hacking and explanation of each subject.

In the beginning hackers was a positive term for someone who mastered computers and could push programs to their limit and beyond. Now we see them as a threat but are they? Some people use hackers to see how penetrable their information is or to act as sheriffs to their information. Even the people, Steve Jobs and Steve Wozniak, founders of Apple computers started as hackers. But as always there is an opposite side to the good side. Hackers can find a way to our credit card numbers, change valuable information on our records, or just make our lives miserable. In the American Heritage Dictionary a hacker is defined as a

. . .
Do you believe them? Some hackers have hacked into banks and transferred up to 70 million in computer related heists. In 1968, ARPANET was founded, which stood for Advanced Research Projects Agency.

Phreaking, a common term used to describe phone hackers.

There are two general methods to hacking: WetWare and technical. The technical method is used by ways of cracking passwords or finding exploits in networks and using these errors to their advantage to gain access to a system network. These types of hackers are known for their abilities to make evaluation copies of applications, those programs that expire within 30 days usually, fully registered and they can also find a way to get the fullness out of demos. It is even available at Barnes & Noble. Only 3,000 people subscribe but over 40,000 get it off the newsstands. This magazine has everything to learn how to phreak and anything else relating to hacking.

Magnetic Levitation Gives Computer Users Sense Of Touch
ScienceDaily (Mar. 5, 2008) — Computers, long used as tools to design and manipulate three-dimensional objects, may soon provide people with a way to sense the texture of those objects or feel how they fit together, thanks to a haptic, or touch-based, interface developed at Carnegie Mellon University.

--------------------------------------------------------------------------------

Unlike most other haptic interfaces that rely on motors and mechanical linkages to provide some sense of touch or force feedback, the device developed by Ralph Hollis, research professor in Carnegie Mellon's Robotics Institute, uses magnetic levitation and a single moving part to give users a highly realistic experience. Users can perceive textures, feel hard contacts and notice even slight changes in position while using an interface that responds rapidly to movements.

"We believe this device provides the most realistic sense of touch of any haptic interface in the world today," said Hollis, whose research group built a working version of the device in 1997. With the help of a $300,000 National Science Foundation grant, however, he and his colleagues have improved its performance, enhanced its ergonomics and lowered its cost. The grant also enabled them to build 10 copies, six of which are being distributed to haptic researchers across the U.S. and Canada.

"We have gone from the prototype to a much more advanced system that other researchers can use," Hollis said. Putting the instrument in the hands of other researchers is critical in a young, developing field such as haptic technology, he emphasized. Though haptic interfaces have uses in engineering design, entertainment, assembly, remote operation of robots, and in medical and dental training, their full potential has yet to be explored. That's particularly the case for magnetic levitation haptic interfaces because so few have been available for use by researchers, he added.

"This is an affordable device that's also practical," said Hollis, who has started a spinoff company to build additional devices. "Now other people can have this technology, and this represents technology transfer in the very real sense."

Six devices will be delivered to researchers at Harvard, Stanford, Purdue and Cornell, as well as to the universities of Utah and British Columbia. All are members of the Magnetic Levitation Haptic Consortium, an international group dedicated to fostering increased use of this technology.

Hong Tan, associate professor of electrical and computer engineering at Purdue University and a consortium member, studies human perception of fine surface textures -- work that requires simulation resolution at the micron level. "This is beyond the capability of most commercially available haptic devices, but the maglev device developed by Dr. Hollis will make it possible for us to continue this research," she said.

"The field of haptic research and development is expanding rapidly," said Rob Conway, project manager in Carnegie Mellon's Center for Technology Transfer. "Carnegie Mellon's research opens new possibilities by joining the world of haptic feedback with a comfortable magnetic levitation interface. The magnetic levitation decouples the interface device from the mechanical world, eliminating friction, backlash, jump, sticking and other interfering effects, so that the user feels only the artificial environment in complete accuracy down to the micro scale."

The system eliminates the bulky links, cables and general mechanical complexity of other haptic devices on the market today in favor of a single lightweight moving part that floats on magnetic fields.

At the heart of the maglev haptic interface is a bowl-shaped device called a flotor that is embedded with six coils of wire. Electric current flowing through the coils interacts with powerful permanent magnets underneath, causing the flotor to levitate. A control handle is attached to the flotor.

A user moves the handle much like a computer mouse, but in three dimensions with six degrees of freedom -- up/down, side to side, back/forth, yaw, pitch and roll. Optical sensors measure the position and orientation of the flotor, and this information is used to control the position and orientation of a virtual object on the computer display. As this virtual object encounters other virtual surfaces and objects, corresponding signals are transmitted to the flotor's electrical coils, resulting in haptic feedback to the user. Hollis and his colleagues will demonstrate the new maglev haptic interfaces at the IEEE 16th Symposium on Haptic Interfaces for Virtual Environments and Teleoperator Systems, March 13-14 in Reno, Nevada.

Sense of Touch Comes to Computers

Who's Blogging» Links to this article
By DANIEL LOVERING

PITTSBURGH -- A controller developed at Carnegie Mellon University allows computer users to manipulate three-dimensional images and explore virtual environments not only through sight and sound, but by using their sense of touch.

The device, expected to be used mainly for research, training and industrial purposes, comes close to the sensitivity of the human hand.

Using magnetic fields, the so-called haptic device replicates the response a hand might have to textures and gravitational forces, said Ralph L. Hollis, a Carnegie Mellon professor who developed the controller. Haptic refers to devices that convey the sense of touch.

"We believe this device provides the most realistic sense of touch of any haptic interface in the world today," he said.

The controller _ like a joystick topped with a block that can be grasped _ has just one moving part and rests in a bowl-like structure connected to a computer. Two of the controllers can be used simultaneously to pick up and move virtual objects on a monitor.

In a demonstration Tuesday, visitors to Hollis' lab were invited to move an image of a pin across a plate of various textures, causing the controller to bump along ripples, vibrate across fine striations and glide across smooth areas.

On one computer, users could "feel" the contours of a virtual rabbit.

Hollis said his researchers had built 10 of the devices, six of which were to be sent to other universities across the country and in Canada, and that a new company, Butterfly Haptics, would begin marketing the device in June or July.

The controller, which Hollis said will cost "much less" than $50,000, could enable a would-be surgeon to operate on a virtual human organ and sense the texture of tissue or give a designer the feeling of fitting a part into a virtual jet engine.

The interface might also convey the feeling of wind under the wings of unmanned military planes, Hollis said.

Hollis and his research team built an initial version of the device in 1997, but refined it _ and lowered its cost _ in recent years with the help of a National Science Foundation grant.

"We have gone from the prototype to a much more advanced system that other researchers can use," he said in a statement.

Haptic devices are not new, and such technology is fast becoming more sophisticated, Hollis noted. Vibrating cell phones and some automotive accessories and video games already convey physical sensations to users.

The system developed at Carnegie Mellon differs from other technologies that simulate hand responses to touch because it relies on a part that floats in a magnetic field rather than on mechanical linkages and cables, according to Hollis.

Computer program to help police track down pedophiles

Program detects patterns by cross-checking messages posted in Internet chat rooms, forums

The Knesset's Finance Committee has approved the allocation of $550,000 to Israel Police for the purchase of a computer program designed to tack down pedophiles, Yedioth Ahronoth reported Wednesday.

The program, which is based on a system that was developed by Microsoft in cooperation with the Toronto police department, has already assisted in the arrest of several pedophiles in the US and Canada.

Using sophisticated alogarithms, the program is able to detect patterns by cross-checking messages posted in Internet chat rooms and forums, thus giving investigators new leads and a list of suspects they could not have tracked down otherwise.

According to police data, 30 cases of computer-related sexual offenses were opened in 2007.

Internet bots,

Internet bots also known as web robots, WWW robots or simply bots, are software applications that run automated tasks over the Internet. Typically, bots perform tasks that are both simple and structurally repetitive, at a much higher rate than would be possible for a human editor alone.
The largest use of bots is in web spidering, in which an automated script fetches, analyses and files information from web servers at many times the speed of a human. Each server can have a file called robots.txt, containing rules for the spidering of that server that the bot is supposed to obey.

cryptography

2008-02-26T15:22:24+01:00

The art of protecting information by transforming it (encrypting it) into an unreadable format, called cipher text. Only those who possess a secret key can decipher (or decrypt) the message into plain text. Encrypted messages can sometimes be broken by cryptanalysis, also called codebreaking, although modern cryptography techniques are virtually unbreakable.

As the Internet and other forms of electronic communication become more prevalent, electronic security is becoming increasingly important. Cryptography is used to protect e-mail messages, credit card information, and corporate data. One of the most popular cryptography systems used on the Internet is Pretty Good Privacy because it's effective and free.

Cryptography systems can be broadly classified into symmetric-key systems that use a single key that both the sender and recipient have, and public-key systems that use two keys, a public key known to everyone and a private key that only the recipient of messages uses.

my guider point of it:
why use the same assignment in two subject?
it also correct(for the reason,every people want a done good work)
my mind point of it:
