iClub - Independence Day, Carpe Diem, what not!
All these come in the way of iClub, but hey, we’re back to rock again. This week is yet another intriguing week for you guys, we have pulled our stockings and are keeping up to the pace. As always we’ve a blend of fun, business, science and their applications along with fun events and quizzes.
The topics that are to be dealt with this week are:
1. Biometrics – Swetha Mohan
Biometrics refers to methods for uniquely recognizing humans based upon one or more intrinsic physical or behavioral traits. In information technology, in particular, biometrics is used as a form of identity access management and access control. It is also used to identify individuals in groups that are under surveillance.
Biometric characteristics can be divided in two main classes:
Physiological are related to the shape of the body. Examples include, but are not limited to fingerprint, face recognition, DNA, hand and palm geometry, iris recognition, which has largely replaced retina, and odor/scent.
Behavioral are related to the behavior of a person. Examples include, but are not limited to typing rhythm, gait, and voice. Some researchers have coined the term behaviometrics for this class of biometrics.
Strictly speaking, voice is also a physiological trait because every person has a different pitch, but voice recognition is mainly based on the study of the way a person speaks, commonly classified as behavioral.
2. Ethical Hacking – Raj Praveen
White hat hackers, also known as "ethical hackers," are computer security experts, who specialize in penetration testing, and other testing methodologies, to ensure that a company's information systems are secure. Such people are employed by companies where these professionals are sometimes called "sneakers." Groups of these people are often called tiger teams or red teams. These security experts may utilize a variety of methods to carry out their tests, including social engineering tactics, use of hacking tools, and attempts to evade security to gain entry into secured areas.
An ethical hacker is a computer and network expert who attacks a security system on behalf of its owners, seeking vulnerabilities that a malicious hacker could exploit. To test a security system, ethical hackers use the same methods as their less principled counterparts, but report problems instead of taking advantage of them. Ethical hacking is also known as penetration testing, intrusion testing and red teaming. An ethical hacker is sometimes called a white hat, a term that comes from old Western movies, where the "good guy" wore a white hat and the "bad guy" wore a black hat.
One of the first examples of ‘ethical hackers’ at work was in the 1970s, when the United States government used groups of experts called red teams to hack its own computer systems. According to Ed Skoudis, Vice President of Security Strategy for Predictive Systems' Global Integrity consulting practice, ethical hacking has continued to grow in an otherwise lackluster IT industry, and is becoming increasingly common outside the government and technology sectors where it began. Many large companies, such as IBM, maintain employee teams of ethical hackers.
In a similar but distinct category, a hacktivist is more of a vigilante: detecting, sometimes reporting (and sometimes exploiting) security vulnerabilities as a form of social activism.
3. Stock Markets – Sarat Chandra
In the middle of the 13th century, Venetian bankers began to trade in government securities. In 1351 the Venetian government outlawed spreading rumors intended to lower the price of government funds. Bankers in Pisa, Verona, Genoa and Florence also began trading in government securities during the 14th century. This was only possible because these were independent city states not ruled by a duke but a council of influential citizens. The Dutch later started joint stock companies, which let shareholders invest in business ventures and get a share of their profits - or losses. In 1602, the Dutch East India Company issued the first share on the Amsterdam Stock Exchange. It was the first company to issue stocks and bonds.
The Amsterdam Stock Exchange (or Amsterdam Beurs) is also said to have been the first stock exchange to introduce continuous trade in the early 17th century. The Dutch "pioneered short selling, option trading, debt-equity swaps, merchant banking, unit trusts and other speculative instruments, much as we know them" (Murray Sayle, "Japan Goes Dutch", London Review of Books XXIII.7, April 5, 2001). There are now stock markets in virtually every developed and most developing economies, with the world's biggest markets being in the United States, UK, Japan, China, Canada, Germany, and France.
The stock market is one of the most important sources for companies to raise money. This allows businesses to be publicly traded, or raise additional capital for expansion by selling shares of ownership of the company in a public market. The liquidity that an exchange provides affords investors the ability to quickly and easily sell securities. This is an attractive feature of investing in stocks, compared to other less liquid investments such as real estate.
Sometimes the market seems to react irrationally to economic or financial news, even if that news is likely to have no real effect on the technical value of securities itself. But this may be more apparent than real, since often such news has been anticipated, and a counterreaction may occur if the news is better (or worse) than expected. Therefore, the stock market may be swayed in either direction by press releases, rumors, euphoria and mass panic; but generally only briefly, as more experienced investors (especially the hedge funds) quickly rally to take advantage of even the slightest, momentary hysteria.
All this and more we can expect from sarat, don’t you guys miss it.
And, Of-course there’ll be the fun events to light up the Sunday and also some quizzes to keep you thinking. Come here to TIFAC Auditorium 11Am on every Sunday and have a blast.
Once again its friendship day today and at iClub we celebrated it differently. Friendship day according to me is not about cheering up your old buddies, hanging out and having fun, it is about making new friends. It’s not the old guys we have to appreciate (friends usually don’t need sucking up to them), it’s the new we have to welcome and so we did. We had fun events which got new people getting introduced, new guys taking part in it and very good interaction. Fun events managed by Abhinash, Aish and Sarat are really good on this front. Chief Guest to this special occasion Mr. Harishreyas of III ECE had come all the way from Trichy just to see his friends on the stage (Now there’s real friendship). He also gave us a piece of inspiring thought (which I forgot) on friendship.
The technical seminar was taken by Akshaya regarding the nanotechnology and everything around it and how it’s changing the world around us without us knowing it. It was very informative, a good presentation which made the technical presentation very lively with frequent interaction with the crowd.
Another technical seminar on “How internet works?” by Raj Praveen was simply wonderful… at least to me, ‘cause I could see some people dropping their heads half way through. But the actual seminar was very very informative regarding the basics of the internet, websites and all other stuff.
The non-tech seminar “Doomsday controversy” by Divya Ravishankar gave us a very good insight about how we’re going to die and lead our lives into Armageddon and the end of the world. It was thorough and informative, insisted on leading lives with an intuition too help preserve the critical balance from which we existed.
1. Everything has a purpose, life on earth, all its living things, the solar system and its actions, everything and we’re yet to find the inner meaning and if we can’t find it we can leave it to be divine intervention.
2. Everything is an accident, A big ball of fire blasted by ‘accident’ and a small chunk cools down on its own accord and ‘accidentally’ finds itself a favorably warm position in the solar system and also bring itself ‘accidentally’ to create amino acids in thunder storms in favorable conditions and needed reactants which eventually by ‘accident’ formed the first living cell and everything ‘accidentally’ evolved from that. Life has no meaning, the universe and our entire physical existence is but an ‘accident’.
But the creation and its meaning aside the end of the world rests in a swirl of imaginations by people who want recognition and all other stuff, for instance the end of Mayan calendar might as well be the end of the world, when were the Mayan’s one of the most intelligent beings on earth, even if they were, their race ended pretty long ago and so are their customs and belief, if they were smart enough to predict the end of the world why weren’t they smart enough to sustain their race, all they believed in was the cyclical nature of the world, the patterns happened in the past will help them in near future but as we know, people evolve, their habits change, new ideas influence new cultures and lifestyle, nobody wants the past they want to be happy about the present and a little bit about the future. The future is like a thought. If Einstein had changed his mind and decided to play football instead of relativity, relativity would be a later invention, thus future is impossible to predict. “But NOOO, Alan we believe in Mayan calendar and the earth is gonna end when it’s predicted.” It’s your fate idiots, live like panicky little baby girls. Nobody’s forcing you!!!
