1989 was a watershed year for both the world in general and me in particular. I had just finished my PhD from the University of Texas at Dallas and had decided to break the jinx of the X+1 syndrome and return to India. Those who have been a part of the desi community in the US in the last century would recollect this strange yearning of those who had finally arrived in the US, not just physically, but metaphorically as well, to give it all up and return to India. Nostalgia for home, sprinkled with a sense of guilt for having abandoned it, competed with la dolce vita, the good life, that America held out to the F-1 visa community of graduate students and it was always that the good life that won out. Most of F1 crowd would eventually get the Green Card, permanent immigrant status, and then become US citizens but they would always keep alive the delusion that next year, X+1, they will wind it all up and move back to India. It was a delusion because India was still stuck in socialist q...

Steve Case is such a big fan of Alvin Toffler’s 1980 classic, The Third Wave, that when he pens his own memoirs he gives it the same title. In his seminal work, Toffler had identified three distinct waves in the evolution of human society as the world moved from agriculture, through industry to become a post-industrial information driven society. Steve divides Toffler’s third wave -- the information phase -- into three sub-waves and then examines the third of this third in greater detail. In addition to being his memoirs, that chronicle the rise and fall of America Online, the company that really got Americans hooked to the internet, there are two other distinct themes that Steve has woven into this easy to read book. First he wants to be mentor and cheerleader for the entrepreneur who has an idea to change the world and does not know how to go about it. The second, and this is pet theme, is the distinction between the first, second and third waves, or sub-waves, of the internet dr...

This blog post will show you how to create a fairly decent website at a guaranteed lowest cost and that too without writing any code. Take a look. This post was originally written for iot-hub and the approach is currently being used at  Yantrajaal as well. However, when Yantrajaal was created in 1999 , none of these technologies existed and I had to take a more expensive route, that you do not need today. credit The first step to creating your, or  your company's, digital identity is to build a website. Most people begin by purchasing web hosting services either from a web hosting company or from a value added reseller and have them build their own website. While this may be fine, a do-it-yourself approach will get you going at the minimum possible cost. This post will tell you how you can do this. 1. Purchase a domain name, from a domain registrar like TierraNet or any other similar company. This will cost you around US$ 14 / year. You can get an absolutely free ...

Hadoop is history and Spark is the new kid on the block who is the darling of the Big Data community. Hadoop was unique. It was a pioneer that showed how "easy" it was to replace large, expensive server hardware with a collection, or cluster, of cheap, low end machines and crunch through gigabytes of data using a new programming style called Map-Reduce that I have explained elsewhere . But "easy" is a relative term. Installing Hadoop or writing the Java code for even simple Map-Reduce tasks was not for the faint hearted. So we had Hive and Pig to simplify matters. Then came tools like H20 and distributions like Hortonworks to make life even simpler for non-Geeks  who wanted to focus purely on the data science piece without having to bother about technology. But as I said, with the arrival of Spark, all that is now history! Spark was developed at the University of California at Berkeley and appeared on the horizon for data scientists in 2013 at an O'Reilly ...

The IIT KGP Pre 1993 group in a facebook was created as a reaction and rebuff to the official IIT KGP Alumnus group that had become a hotbed of political and religious bigotry. The Pre 1993 crowd is believed to be more of the "kool kgp type" and even if some of them do have strong views on political and religious matters, such things are kept aside in this group. Posts in this group are more in the form of happy reminiscences that the old men like to tell, listen to and enjoy. Since it is difficult to search through Facebook posts, I have created these pointers to the stories that I had contributed to this column. But to respect the privacy of the closed group where these stories were pointed, I have made sure that only members can read the whole story -- and the incredible comments that other members have made. 6th July 2015 Sometime in the recent past,  Surath Chatterjee , like many of us, reached his 50th year and some of his friends had thrown a party for him a...

When I think back about it, the New Delhi that I had visited as a child in the late 1960s was so much cleaner, nicer and better than the city I occasionally go to today. As a tourist in Europe in the late 1980s I did not have to think about the terror, and counter-terror, that is now being unleashed in Brussels and Paris. The Kolkata that I live in today is an urban disaster compared to the Calcutta that I went to school in. It is difficult to deny that, net-net, there has been a decay and degradation in the quality of urban life over the past 50 years. Is it only in urban life? And is it only for the past 50 years? The dry statistics captured by economists in the Human Development Index -- a vector consisting of life expectancy, education and per-capita income -- and talked about by governments in power would claim that the world is becoming a better place. But the common man in the bazaars of India, and perhaps the world as well, would beg to differ. With his native intelligence,...

Journalists could be an endangered species as more and more newspapers and magazines lose readers to free websites on the internet. While the reach offered by a website is immense, what is disturbing is that the author / journalist is hardly ever compensated for his effort in putting together an interesting article. Many business models have been tried, including paywalls, where readers have to pay to access content and free-mium where a part of the content is free and the premium content has to be paid for, but the lure of the completely free competitor is irresistible. Once readers are accustomed to free content, it is almost impossible to wean them away towards making payments. So is the case with other intellectual property like computer software and college textbooks. Even if we ignore direct criminal acts like piracy and photocopying of books, the existence of free and open source software and websites that offer educational content have curtailed demand for paid products. Some...

As a prolific user of Twitter, I have more than 11K tweets on my timeline but I realised that in most cases I have either retweeted others' tweets or at best forwarded or commented upon the contents of various websites. How many times have I said anything original? Actually not a trivial number! I have nearly 4000 original "words of wisdom" that I hereby bequeath to posterity! How did I arrive at this list? Well I downloaded all my Tweets till 5 March 2016 into a spreadsheet and then using some simple text processing commands, I eliminated retweets and any tweets that contained a reference to any URL. Unfortunately that eliminated tweets referring to my own work as well but that was the price I had to pay to create this. Finally, here it is ... a collection of my pure and original thoughts from the last seven years!

Rise of the digital autonomous corporation Think of a company that offers a service that helps people track their assets and transfer the same to others on the basis of validated instructions -- similar to a current account with cheque facility. Think of the same company as hiring people to do this and paying them for their effort with shares in the company -- sweat equity. Think of this company as being in operation since 2009 and the value of its shares spiking to US$ 1200 before stabilising at around US$ 200 over the past two years. Think of this company having a current market capitalisation of around US$ 5.5 billion. Now what if this company were to have to no human managers and but only programs on multiple computers interacting with each other!  Is such an unmanaged company possible? Strangely enough, it is possible, it does exist today and it is called Bitcoin. The only twist in the the tale is that the only asset being tracked by the company also happens to be the sh...

India has a glorious tradition in higher education that stretches back to the hoary antiquity of Nalanda and Takshila but today this tradition is under stress. We have too few colleges for our kids and most of these lack the infrastructure (“hardware”) or the faculty (“wetware”) necessary to deliver the kind of programs (“software”) necessary to be world class institutions. In an earlier article we had explored how inexpensive technology could address this problem and here we explore structural issues that may offer useful alternatives. image indolinkenglish There are different kinds of reasons why we do not have enough good colleges. In the case of government, or public-sector, colleges it is a combination of lack of money, mismanagement and political interference. Central universities and institutions are better off but they too are plagued by cronyism and inefficient use of money. Instead of creating multiple IITs and IIMs in far flung parts of the country we should have incre...

Management education in India is in crisis. Enrollment is falling as students realise that jobs for freshly minted MBAs are nowhere as abundant or glitzy as they used to be in the past. MBAs still get recruited because earlier batches of MBAs are in middle management positions and they need more of their type to keep their own brand value high but in the upper echelons of corporate India their presence is rare. Finally hordes of B-schools, all trying to model themselves as third cousins of IIM Ahmedabad, and handing out PGDBMs by the hundreds have reduced the value of the certificate to the level of a B.A. or B.Com. degree. Necessary but not sufficient for low paying, white collar “executive” jobs so beloved of middle-class India. But management skills is really, really what India needs. There is no dearth of high technology in the corridors of organisations like TCS, L&T, ISRO, SBI, Mahindra, NTPC, ONGC, DRDO and yet we somehow cannot bring it all together in a manner that can ...
