James Cameron's Avatar is old wine in a brand new and spectacularly brilliant bottle. There is nothing new in the plot -- especially for those of us in India who have been following land acquisition battles in the tribal belt -- that pits the indigenous people as the underdogs who are battling to save their forest-based way of life from the clutches of a global ( universal ?) megacorp. Latched on to this main plot is a cameo sub-plot of a cute little love story between two individuals Jake Scully (Sam Worthington) and Neytiri (Zoe Saldana) from the two opposing camps, which again is nothing to write home about. But what makes the movie remarkable and memorable is the concept of transferring identity and consciousness ( "soul" ? ) across two bodies -- one of which is a genuine human and the other a synthetic Na'vi humanoid. Cameron has referred to this synthetic humanoid as an Avatar which periodically receives -- and is animated by -- the hero, Jake's soul. The...

With the debacle of the CAT getting out of the bag and the rubbish of it being attacked by a virus being bandied around by semi-literate experts, I thought of digging deep into the innards of my laptop and locating a very simple tool that I had built a long time ago to automate the evaluation of examination scripts. Despite all the progress made in telecom, internet connectivity remains a challenge especially when you have to consider users who are not only geographically dispersed but who have to operate in conditions that an American company like Prometric/ETS really cannot envisage. A design for India has to factor in a breakdown of communications and this is where the store-and-forward technology [ first used in the now defunct Lotus Notes product ] can provide a good model. KwizAuto - the tool that I had built while teaching at the Praxis Business School, Calcutta is based on Excel and it works like this : Have KwizAuto available on the test machine or download it from...

Many professionals in the corporate sector, who enjoy handsome take home salaries today dream of early retirement. The thought of being free from client and performance pressures and the lure of chasing down all those hobbies that one had to sacrifice at the alter of the corporate employer is extremely seductive. But an early retirement would mean that one should have a corpus of money that should be enough to cover the household expenses for the rest of ones life and that of the spouse. So how much money must one have on retirement day so as to sustain the lifestyle that one is accustomed to ?  How should one calculate what is required ? Consider the following points Inflation will increase your household expenses every year ? And this increase is not a simple linear expenses. It will follow the compound interest law.  Your corpus will also grow as per the compound interest law. Interest rates are corelated to inflation. When inflation goes up, so does interest rates...

Now that I have grabbed your attention with a couple of big and high sounding words let me justify their use in the title of this post. In any discussion of the Indian State, the first image that pops into our mind is that of the parade with which our armed forces salute the State -- through the person of the President -- on Republic Day. The spectacular nature of this parade, the precision with which the contingents -- both military and civilian ones -- walk, move, act and enact various scenarios is of course something to be proud of but the tragedy of the parade lies in the fact that it has no relation to the way the State actually works outside the parade route. Were we to move away from Rajpath and step into the dungeons of any sarkari daftar , the reality that will confront us is terrifying. Decrepit and stained with betel juice and with piles of dusty files covering innumerable empty desks, government offices -- whether central, state, municipal, panchayat or public sector ...

With an obsession with placements , Business schools in India -- IIMs not excluded -- have degenerated into thinly disguised placement agencies or at best glorified vocational schools. The compartmentalisation of B-school curriculum into the four principal management functions, namely Finance, Marketing, Human Resources and Systems and Operations reflects this mindset. These are the four principal kinds of tasks that a manager is expected to perform and B-schools pat themselves on the back if they can teach these four skills to the satisfaction of the recruiting companies. [ Though in reality, companies that hire from B-Schools do not seem to care for even this skill ...] Unfortunately, this puts B-schools in the category of vocational schools or V-schools If we draw an analogy with engineering schools, this approach would mean that students are taught workshop practice -- chipping, fitting, foundry, welding -- assembling circuit boards or laying out wires for electrical circuits ...

Why do students queue up to get into B-Schools, especially the more well known ones ? And why are some B-Schools more well known than the others ? Both questions are in fact two sides of a more fundamental question - what value does a B-School bring to the table ? and the answer to both questions can be found in the placement history of B-Schools in general and specific schools in particular. Students join B-Schools because they believe -- and in many cases, quite rightly, that it is a ticket to a high paying job and some B-Schools are more well known than others because their students end up with more, better or higher-paying jobs. But why blame B-Schools for this trend. In the 70s, 80s and even as late as the 90s when unemployment was the dominant feature of the economic landscape of India, students would throng the gates of the Engineering schools because because that was seen as the most sure shot ticket to a good job. Students who had neither the inclination nor the aptitude...

Sandhi puja is perhaps the most significant event in the entire sequence of rituals that constitute the autumnal adoration of the Goddess -- the Durga Puja, but not too many are aware of the legends that have invested this event with the aura of extreme sanctity. Sandhi means junction and in this case it is the junction between the eighth and ninth lunar day after the first new moon that occurs after the sun moves into Virgo -- as per the Hindu zodiac, which lags the Christian zodiac by the Ayanamsa value of around 23 degrees. That is why the ritual is performed in the last 24 mins of the Ashtami ( the 8th lunar day ) and the first 24 mins of Navami (the 9th lunar day). Legend says the Goddess in her manifestation of the Mahishasur-mardini, the destroyer of the evil ogre who took the form of a buffalo or Mahish, performed her deed at this precise moment and so at this auspicious hour the manifestation of divinity is at its peak in the clay image that is generally used to represent...

Maureen Dowd in her op-ed article -- Blue is the new Black -- published in the New York Times has referred to a survey that, if really true, should force us to seriously rethink the outcome of the War of Civilisations. But first what is this survey all about ? " According to the General Social Survey, which has tracked Americans’ mood since 1972, and five other major studies around the world, women are getting gloomier and men are getting happier " .... First there is no further reference to this General Social Survey and to the five other major studies ... but we shall let that pass and focus what appears to be the core of Dowd's hypothesis. The reason that women are getting gloomier is because they have more choice today ! In the past, before feminist activism unshackled women from petty domesticity, women lived lives that were tightly controlled by the men in the family -- father, husband, father-in-law and son. They basically did what they were told to do ... and tha...

The evening of Mahasaptami at Sonartoree, Prantik, Birbhum

Kankalitala is one of the 51 Shakti Pithas in the Indian sub-continent and is a place of pilgrimage and tourism for those who visit Shantiniketan. While most visitors are happy to visit the tiny shrine of the divine mother, not too many take the trouble to walk another 100 metres to the shrine of the Pitha Bhairab -- the consort of Shakti -- who is referred to here as Ruru Bhairav. But those who do, get a glimpse of one of the darkest images of medieval Bengal. Sulaiman Khan Karrani was the Pathan who ruled Bengal in the second half of the 16th century and his general KalaPahar [ the black mountain, perhaps an allusion to his physical size ], a Hindu who had converted to Islam was notorious as the demolisher of temples in Bengal and Orissa. Legend claims that he was finally killed before the temple of Sambaleshwari by the goddess herself in the guise of a milkmaid who seduced him and his people with a gift of milk and sweets that was laced with cholera germs. Kala Pahar is known to ...

I have been teaching Quantitative Techniques [ or more simply Statistics and Probability, for those who have given a miss to B-schools ! ] and as a part of my course I have taken the liberty to "borrow" heavily from the work of other teachers and professors who teach similar things in other parts of the globe. With all the talk of digital rights management and ownership of IP I feel rather guilty for having done so ... I could have of course acknowledged the origin of the information but since I have accumulated all this for a number of years, I really have lost track of what I got from where ! So I thought of doing something else -- and have decided to publish my entire set of slides under the creative commons license. Anybody who wants to teach Quantitative Techniques [ at least the first, introductory part ] is welcome to use my slides. This covers a little less than 30 hours of class room contact, with the rest being used to solve problems from the text book by Levin ...

Mahalaya -- celebrated on the day of the last new moon before Durga Puja -- is when many of us in India perform tarpan : a solemn act of remembrance of our ancestors. Those who have the inclination and the time perform this on the banks of Ganga, the Hooghly or any other river that they consider sacred. In view of the pressures of time, many of us prefer to remember our ancestors in the privacy of our homes but in this age of the Internet, I thought that it would be a good idea to dedicate this post to my ancestors without whom I would not have been here.

We come across, and frequently use, the phrase red tape and we know that it refers to the delay that is endemic to the bureaucratic process - but have you ever wondered why is that bureaucrats are so slow in doing things ? Anybody who has visited a government office in India would of course attribute this delay to competence or corruption. More often than not, a little bit of speed money -- the chaipani -- has a magical effect and most red tape disappears. On the other hand, we do know that the best and brightest in the land are hesitant to join the government and so there does exist a certain lack of competence in administrative matters. But let us be charitable for a while and assume that our bureaucrats are indeed competent and NOT corrupt : in that case should red tape not disappear from our lexicon ? But it does not and will not .. and here is why ! You ask a sarkari babu to buy a computer for his office and he ( or she ) will get tied up in knots ! Committees will be formed, spe...

While I do appreciate abstract art -- particularly shapes and colours that please the eye -- I do not always agree with the statement that "if you are looking for meaning in art, then you are barking up the wrong tree". Shapes, patterns and colours are nice but they are even nicer if they can communicate something that you recognise and can identify with. I came across these paintings by Devajyoti Ray at the website of Galerie ArtEterne and was very impressed by both the form and the content.

source : Gartner Report Every new technology ( or idea for that matter ) that appears in the human psyche goes through the phases shown above [ see chart ] if they survive adolescence and enter maturity. Virtual Worlds, Web 2.0 and Cloud Computing are three ideas that keep churning through my thoughts and I was pleasantly surprised to find the three of them being addressed in the Gartner report on technology hypes. Being an early enthusiast of and evangelist for Second Life -- the 3D Virtual World where I had first set up my first Kali Temple and virtual Praxis B-school -- I had been resigned to the fact that low penetration of personal broadband lines will hamper the growth of this wonderful technology. But I was pleasantly surprised to discover that Second Life has posted a 94% QoQ growth and now has nearly US$ 50m of user to user transactions every month . Also the availability of Wireless Broadband from the CDMA players will accelerate acceptance and finally pull it out of the ...

Onward Software Soldiers, marching as to war, With a Chrome-on-Linux going on before, Google, the loyal Master, leads against the foe; Forward into battle, hear its trumpets blow. Predictions are hazardous and emphatic ones even more so -- for the credibility and reputation of the predictor -- but let me stick my neck out anyway and state that Google Chrome might just as well drive a stake through the heart of the proprietary and paid-for software story. The ethic of reciprocity also known as the Golden Rule is an ethical code that states one has a right to just treatment, and a responsibility to ensure justice for others. One of the many ways of expressing this ethic is "do not do to others what you would not like to be done to you". Microsoft violated this code when it killed Netscape by bundling a "free" browser with its dominant operating system but having sowed the wind, they now reap the whirlwind as Google plans to ship a free operating system along with th...

An open letter to ... Mr Kapil Sibal, Minister for Human Resources Development Government of India Dear Sir, Mr Sibal Your thoughts on the abolition of Class X examinations and the introduction of a single nationwide Class XII examination are like the winds of change that should blow away the cobwebs from the stultifying and claustrophobic classrooms to which we in India have condemned our children. You would of course know that in the United States, a similar system is in place with students – if they wish to join college – having to take only the SAT examination. Our Class X examinations serve no purpose but to allow students to enter Class XI. Our Class XII examinations are no better – they merely serve as entry portals to colleges and in the case of engineering colleges, even this nominal and residual value is ignored because every college has its own entrance examination – nobody trusts the Class XII results. So no tears should be shed if these two examinations are consigned to ...

A slightly modified version of this interview has appeared in today's edition of the Economic Times. What is Cloud Computing ? Cloud Computing is less about any particular technology and more about how we use technology to reduce costs and improve efficiency. In Cloud Computing you move your data - and the programs that operate on this data - from private machines - desktop PCs or corporate servers - to machines owned by vendors. How does this help ? It reduces cost - both capital and operating, through economies of scale. It is like replacing the electricity generator in your home by plugging into the electricity supply : the cost and nuisance value of generating power at home is far more than having it supplied from a central utility. When a vendor supports a hundred customers with his bank of servers and support staff the cost to each individual customer goes down. An intriguing concept, but does it work ? Many of us are already using Cloud Computing without being aware of...

Web 2.0 in general and social networks, like Orkut and Facebook in particular, have emerged as very powerful models of social interaction ... so much so that Iran is trying to quell its election related insurrection by trying to block Facebook and the US Government convinced Twitter to defer its scheduled downtime so as to allow Iranian thought processes to play out to their full potential !! While Orkut and Facebook are privately owned public platforms, we know that similar ( if not identical ) platforms are available to build own's one private social networks. For example we at the Praxis Business School, in Calcutta have our own platform, the Kollaborative Klassroom ( see http://kk.praxis.ac.in ... to know what i mean ) that we have customised to reflect our own organisation ( courses and departments defined as "communities" and "friendships" that delineate relationships between individuals) Currently employees of the government operate on a diverse set of p...

Refugees have traditionally been associated with political upheavals. We have had Jews seeking refuge from Nazi Germany, dissidents seeking refuge from Russia, China and other totalitarian communist nations and closer home we have had Bengalis seeking refuge from the murderous regime in erstwhile East Pakistan. Then we had economic refugees who sought to flee their homeland not because of political persecution but because of economic need. One cannot argue with an empty stomach and their are parts of the world where an empty stomach is rule rather than an exception. This explains the exodus from South and Central America towards the land of milk and honey to the North. So is the case of economic refugees fleeing Africa for Europe and closer home we once again have had people from Bangladesh coming across the border into India and West Bengal. But political refugees and economic refugees are now old news … The latest development in field of human misery and migration is that of the envi...
