Pray for me brother by A. R. Rahman

March 19th, 2007 by gaurav

His-awesomenesses A. R. Rahman (Yes, he is that good. Both a formidable composer and a very good singer. More on Rahman soon.) recently released a single and accompanying video called Pray for me brother. There was some hype over the release of the video. Normally, everything by Rahman deserves a careful listen. Rahman’s music never sweeps over you. It seeps into you, gradually, after you have heard it a couple of times. I have heard it many times now and I am surprised at how mediocre both the song and video really are. See and judge for yourself.

Internet Radio in trouble.

March 17th, 2007 by gaurav

A recent ruling by the US Copyright Board has been judged to be a death blow to internet radio stations. It proposes new royalty rates for the operator of these stations which remarkably, also apply retroactively. These proposed rates are stratospheric. Most of these stations operate with razor thin margins, so this sounds a death-knell to their existence.

For me personally, this is very very disheartening. I am not a native English speaker and western music (and here I include all genres like pop, rock, jazz, hip-hip, trip-hop, what-have-you) has been an acquired taste over the years. Not only has Internet radio has been the only source of diverse music for me, it has been an education tool. The playlists on these stations Introduce me to new sounds every day. Take a look at the number of channels at SomFM, the playlist at Radio Paradise, or at KCRW. When you discover sounds you discover a culture, you discover people and you discover a country. The blues find their genesis in the US. If I listen to B. B King or Stevie Ray Vaughn I am tempted to find out about them. In turn, I discover what made the men and their music. This chain of action would have led me discover all about the roots of blues and follow the players. If I follow the discussion thread on Beatles’ landmark A Day In Life I am not only part of a community, I also learn peoples ideas and opinions on what makes the song great. DJs like Bill Goldsmith at Radio Paradise or Nic Harcourt at KCRW talk to you. They are running these programs because they care about the music and you can see the care they take in programming the playlists. This kind of interaction, diversity or commitment to presenting music in a way that’s always fresh is wholly absent from commercial radio.

There is a growing movement afoot to get the ruling reversed or at least get the terms changed. I hope that it does get changed. My personal interest aside, it does look like a simple evolutionary step. Since I am not a US citizen I cannot get directly involved but I can give you these pointers on this issue and calls-to-action.

    Why blogging has taken off

    March 16th, 2007 by pranav

    I have often wondered why blogs have become so popular. Recently, it occurred to me that Bloggs and allow us to express incomplete thought. By definition, we humans are lazy and, would prefer just to sent ideas into the ether. It is this tendency that blogs allow was to express that too, without any criticism and with perfect legitimacy.

    In Calcutta

    February 20th, 2007 by gaurav

    I’m in Calcutta right now and it amazes me how much of the city resembles Bombay. Like Bombay, the city has a lot of character and driving here is far less aggravating than in Delhi (where I live), although the roads are as crowded as in Bombay. Like Bombay, it has the same narrow roads winding through old dilapidated buildings. More often than not, when you enter these buildings you’ll find the inside is maintained very well. It’s not uncommon to see a spanking office that has not been painted for years from the outside. The reason, methinks, is very simple. The inside of a building, be it a house in an apartment complex or an office in a larger commercial building, is managed by the people inhabiting it. They have every wish to make it appear neat and clean. However, when it comes to the outsides, nobody cares. It is a symptom of how we Indians lack a civic sense. Somehow, we never developed a shared interest or stake in either the development or the maintanence of these non-private areas of a city.

    Sidenote #1: Calcutta is now called Kolkata and Bombay is Mumbai but I hate those new names.

    Sidenote #2: Here’s a picture of a shopping complex called Newmarket. It’s called Newmarket, but it’s freaking old. The place has a very old bakery called “Nahaums” that has the best Brownies that I have ever had, and I have had brownies in a lot of cities in the world.

    I finally get talking Linux

    February 6th, 2007 by pranav

    I finally got talking linux. I found a talking nopix distribution at http://www.oralux.org. It has a variety of editors. Now to figure the keystrokes. They are radically different from Windows.

    Songs of the Week

    December 15th, 2006 by gaurav

    All of these songs are instrumental. Most might be filed under any one of the downtempo/ambient/trip-hop label. However you classify them, it’s great music. Alphabetically arranged, if I might add.

    Bonobo – Days To Come (feat. Bajka) from Days To Come

    Bajka sounds like a better version of Macy Gray.

    Bonobo – Recurring from Days To Come

    Boards of Canada – Skyliner from Trans Canada Highway

    Calexico – Pepito from Feast of Wire

    If I decide to make a Top 10 album list, Feasts of Wire would be a surefire contender.

    Cantoma – Pandajero from Cantoma

    Gustavo Santaolalla – Iguazu from Ronrocco

    This track also appears on the soundtrack to the movie Babel, released this year.

    LCD Soundsystem – Great Release from LCD Soundsystem

    There might not be anything exceptional happening here but I love the way it builds up.

    Peter Gabriel – In Doubt and A Different Drum from Passion

    One of my favorite artists. These two pieces appear on the album in sequence and have to be heard that way.

    Porcupine Tree – .3 from In Absentia

    Great band, great song, terrible album art. Some perfunctory lyrics are peppered here and there so it’s not strictly instrumental but who cares. Porcupine Tree might be one of the very few *rock* bands around who are doing something interesting and genuine.

    Sigur Ros – Glósóli from Takk

    I love songs that rise to a cacophonous climax the way this one does. You won’t understand word of what they say – not because it would be a foreign tongue to you, but because it’s in a wholly invented language. You can find the accompanying video here. The video is a thing in itself.

    Thievery Corporation – Warning Shots (feat. Sleepy Wonder And Gunjan)

    Stem cell banking

    November 11th, 2006 by pranav

    I just read an article on stem cell banking and how it is becoming the in-thing as a retention tool. What is the big idea? The technology is not there yet. The scheme seems to be that the employer will pay half the cost on stem cell banking and the employee pays the rest. If the employee leaves in say a year, he has to pay a certain percentage of the cost that the employer has paid. This percentage progressively decreases as the tenure of the employee increases.

    So, what is new? As usual, they do not seem to be fixing the root causes of employee atrition.

    Windows Vista review

    Needless to say, accessability is not covered. I wonder how adaptive technology will handle all these new graphics? Also, how will access technology cope with the new security mechanisms?

    Back from a brief hiatus

    October 17th, 2006 by gaurav

    The past two month were gobbled up entirely by work. Now the tight work schedule is er.. not so tight, so I have time to put some thoughts to paper. Will be posting soon.

    The spectre of age

    October 2nd, 2006 by pranav

    I spoke with my grandmother a few hours ago. She sounded surprisingly aged and if I hadn’t known otherwise almost drunk. I was unable to sustain even a basic conversation with her. Is this age? Or is it medicines? 16 months could not have made such a difference.

    Why Veronica Mars, you are a warrior

    August 26th, 2006 by gaurav

    Meet Veronica Mars – gutsy crime fighter, loving daughter, purveyour of smart aleck comments and a class warrior. If you have not watched it yet go get the DVD right away. It’s one of the most interesting shows made in the recent times and is in it’s third season. One of the things that I enjoy the most (apart from the well written storylines and characters) are the snappy conversations between Veronica and her father, played by Enrico Colantoni.

    Of Poincaré conjecture and maths

    August 25th, 2006 by gaurav

    Poincaré conjecture is a mathematics problem that (as I understood it) deals with the structure, nature and properties of the three dimensional space that we live in. This region of three dimensional space is referred to as a 3-manifold. The fundamental structure of the shape we live in is a difficult thing to determine and comprehend because we are situated in the space. Henry Poincaré was a French mathematician who, nearly a 100 years ago, proposed a way to understand how space would look from the outside, looking in this three dimensional space. The problem can be restated as trying to determine the shape of very large object in relation to a human, say trying to determine whether or not earth is flat or to trying to define what a hole is. The absence of matter surrounded by matter would probably be an inadequate mathematical answer for the latter!

    His approach, as explained by Keith Devlin in a recent broadcast of Forum[1], was as follows. Assume that you start from some arbitrary point in the universe and travel for a very long time taking arbitrary turns, leaving a string in your wake all this while. After this rather long travel, where you were leaving a snake trail of string all the while, you proceed to return to the point you started from. You then proceed to pull the string together tight, holding both the ends of the string, trying to close the loop formed by holding both ends of the string in your hand. If you are able to pull this string till there is no loop and end up with a point then we can determine that the space that covered during the course of the travel is really, well, as unremarkable as it looks from the inside. It essentially has no definable characteristic shape in three dimensions. If, however, we are not able to tie the string to get a point, it’s whole different story altogether and the space you covered would look different from the outside and would have a definable shape. It’s almost like if were living in doughnut shaped planet, had traveled over the ring of the doughnut and then trying to close the loop. We would not be able to tie the string to a point in that case. This was the idea that Poincaré thought would help determine how space looks from the outside. So Poincarés conjecture would help answer question on the shape and nature of this space. Questions like what is the simplest 3-dimensional space, what are their properties, among others. Poincaré’s conjecture was in the news recently because a Russian mathematician named Grigory Perelman recently got awarded a very prestigious award in mathematics called the Fields Medal for providing a proof for this conjecture. A proof that essentially says that Poincaré’s idea was indeed correct and would work to determine the nature of 3-dimensional spaces.

    What made this story very interesting was the human drama leading to Perelman getting the award. It involves a whole cast actors, among whom is a prominent scientist of Chinese origin, Shing-Tung Yau. Proving such a theorem is not a discrete step. There are a lot of intermediate steps involved, one research playing into the other, one insight being built upon and used by the other to come to the final conclusion etc. The latest edition of the New Yorker magazine has a lengthy feature on the events and the people involved in this story. Yau make a claim of playing a much larger role in the development of the solution, if not the claim of being the sole person solving it. His almost militant interest to get credit stems in large part due to his desire to cement his status as the leading scientist in his native China. Perelman himself is a rather singular character. He fits the stereotype of the obsessed scientist to the tee. He is ultra reclusive, lives in Russia with his mother and refuses to accept the award because he does not find any significance in it, purity of purpose being the only ideal. There is, however, near universal recognition of Perelman’s contribution in developing new and profound mathematical constructs that form the essential tools to construct and understand the proof.

    Keith Devlin mentions that often its these mathematical constructs and insights that are probably as important, if not more so, as solving the actual problem itself. Consequences resulting from Poincaré conjecture have already been studied from all points so finally knowing that the theory does indeed hold, is not all that important. He says that the constructs developed by Perelman will prove to be invaluable in solving equations in physics that “develop singularities” when applied locally to small areas. (I cannot claim to understand what these are so here’s a link that talks about them). His constructs will help physicists in controlling these singularities. The steps involved in solving a problem of this nature are as important as the result itself. They lead to development of ideas, constructs and tools which themselves reveal hidden structures and truths that not only help evaluate a theory, but also lead to significant and possibly hidden truths and relationships.

    To elaborate on this point, Douglas Hofstadter (who was the other guest on the program with Keith Devlin and who wrote that mind-bending book Gödel, Escher, Bach: An Eternal Golden Braid which is a potential subject of a post in itself) gave the example of prime numbers. Prime numbers are an oddity because they do not seem to fit any particular pattern. The existence of primes has been known for thousands of years. You can divide prime number in different classes in many different ways. Besides 2, all the prime numbers are odd numbers. Now, there are two types of odd primes. Those that are 1 greater than a multiple of 4 e.g. 41 which is 40 + 1, 40 being a multiple of 4, and those that are 1 below a multiple of 4 e.g. 43 which is 44-1, 44 again being a multiple of 4. Although there are infinitely many numbers in both classes, these two classes of primes have a fundamentally different nature. There is a very interesting connection that can be drawn between these two classes of primes and squares. It turns out that primes of the former class can always be represented as the sum of two squares. Taking the example of 41, the square would be 25 (5 squared) and 16 (4 squared). What’s more, they will always be exactly one pair of squares that will add up to this prime! And what about the other latter class? Well, for that class there is no pair of squares that will add up to the primes in that class. So there turns out to be this unexpected connection between squares, which are easy to think about and are predictable, and prime numbers which are so very irregular. In nature too there are so many patterns that we come across everyday, but rarely realize how they are so closely related with mathematical symmetries and relationships. The petals of some flowers are arranged in fibonacci symmetry, earth is the perfect shape for minimising the pull of gravity on its outer edges – a sphere (although centrifugal force from its spin actually makes it an oblate spheroid, flattened at top and bottom)[2], bees construct the beehive made up Hexagons because a hexagon fits most closely together without any gaps which maximise the use of space[2] and so on.

    Goodbye pluto

    August 24th, 2006 by gaurav

    The International Astronomical Union has voted through a new definition criterion for what qualifies to be called a “planet” (I was talking about it a couple of days back). The result of this exercise is that we now cannot call Pluto a planet.

    What that means is that a) course books all over the world will have to incorporate the change, and b) include the new more rigid definition of a planet. It would be fun to see how they do that because the new definition is such that the footnote caveats section reads as long as the definition itself. To the IAU has decided to seed the set with eight planets; Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. They will work from there, newly discovered objects will be included in the set if they satisfy the new rule. The beeb had this to say on the news item.

    Magic mushrooms

    August 24th, 2006 by gaurav

    The latest issue of Scientific American has a small half-page article about a study done at the John Hopkins University on Psychedelic mushrooms and their effects. According to the article:

    One third of volunteers given psilocybin, the mushroom’s active compound, described it as the most spiritually meaningful experience of their lives, and about two thirds rated it in their top five.

    I might add the study group consisted of (only) 26 “spiritually active” volunteers. The article goes on to say the following about the mental state of participants some time after the experiments were conducted:

    Two months later 79 percent reported moderately or greatly increased well-being or life satisfaction compared with those given a placebo.

    Hmmm.. so getting high might really be showing the influenced mysteries of the universe then. So says Mark Morford of the San Francisco Chronicle in this humorous article.

    9 planets?

    August 22nd, 2006 by gaurav

    So you thought that there were nine planets in the solar system? If a current (rather controversial) proposal by the IAU (International Astronomical Union) gets adopted, there would be at least three new planets added to our solar system. The change would occur because the definition of what exactly a “planet” is, would be redone. According to the new definition (via. space.com),

    A planet is a celestial body that (a) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (b) is in orbit around a star, and is neither a star nor a satellite of a planet.

    There are other rules apart from the basic definition above. This is still a proposal and the IAU is going to vote on it on August the 24th. If it goes through we might end up getting not just 3, but possibly many more planets to call as part of our solar system.

    It’s funny when you read about this. When we come across a line that says “there are nine planets in the solar system”, a lot us would just accept that at face value, or maybe not exactly bother to ask what qualifies a celestial body as a “planet”. But now it appears there never really was a scientific definition of what exactly a planet was in the first place.

    Wal-Mart profits decline

    August 16th, 2006 by gaurav

    Wal-Mart is like a whirlpool. It seems to suck the life out of mom-and-pop shops and small vendors in whatever neighborhoods it decides to land. That might very well be free-market economics in all it’s glory, people demand low prices, people get low prices, but it sure is not pretty. The ungentle giant, which merits an active and exclusive detractor website, saw it’s profits decline according to the quarterly report released by the company. It looks like a combination of factors. Pulling out of foreign markets like Germany (where one of the reasons identified was that Wal-Mart clerks were seen to smile a little too much) and Korea, high cost of oil, and “costly overhauls of their marketing, merchandising, and staffing” being the chief among them. This at the same time when it announces it’s supposed to be *cough* going green. Let’s see how green Wal-Mart gets and how and who they squeeze in this process.

    The Mumbai blasts

    July 12th, 2006 by pranav

    A few random thoughts on yesterday’s bomb blasts in the Mumbai local trains

    1. Expect communication systems such as mobile phones to fail. This is why, redundancy in communications systems is crucial. For instance, my landline and mobile phone were jammed such that I was an able to reach anyone however, my broadband connection kept Humming along and I was able to make contact.
    2. I wish hospitals were better managed and someone had posted the lists of the dead and injured on the Internet.
    3. Hats off to the city administration and the railway officials for resuming services just 4 hours after the blasts.

    The good side of technology with frills

    July 12th, 2006 by pranav

    I was watching the television after the blasts and caught the broadcast at a point when no news was available. Pictures via MMS (multia-media messaging service) began to trickle in along with descriptions of the effected areas. I have encountered several people who wonder what is the use of mobile phones with frills such as cameras. Those of you who caught the post blast broadcast of NDTV need not wonder. Those MMS pictures were the first that any one saw of the aftermath of the blasts. So, go for the latest technology and learn how to use it.

    Rebuttle to the NYT article “The Myth of the New India”

    July 7th, 2006 by pranav

    A friend sent me the above article and asked for my comments. My comments are prefixed by “PL]” without the quotes.

    :: This sounds persuasive as long as you don’t know that Mr. Mittal, who lives in Britain, announced his first investment in India only last year. He is as much an Indian success story as Sergey Brin, the Russian-born co-founder of Google, is proof of Russia’s imminent economic superstardom.
    PL] It is entirely up to mr. Mittal to decide where to invest. Not investing in one’s country of origin is no cause for blame. It is not a case so much of an Indian success story but a person of Indian origin succeeding.

    :: But trade and cooperation between India and China is growing; and, though grateful for American generosity on the nuclear issue, India is too dependent on Iran for oil (it is also exploring developing a gas pipeline to Iran) to wholeheartedly support the United States in its efforts to prevent the Islamic Republic from acquiring a nuclear weapon.
    PL] India voted with the USA on condemning Iran’s nuclear program. Plus, that pipeline will have to pass through Pakistan which could be a significant stumbling block. Trade with China is indeed growing but then that is business.

    ::> But the increasingly common, business-centric view of India suppresses more facts than it reveals. Recent accounts of the alleged rise of India barely mentioned the fact that the country’s $728 per capita gross domestic product is just slightly higher than that of sub-Saharan Africa and that, as the 2005 United Nations Human Development Report puts it, even if it sustains its current high growth rates, India will not catch up with high-income countries until 2106.
    PL] Part of this is due to a lack of government reform. Politically, the stumbling block is the communist party. Rural India is good at doing business. I used to employ a driver. One of his relative’s used to buy cooking oil from some place and sell it in villages.

    :: Malnutrition affects half of all children in India, and there is little sign that they are being helped by the country’s market reforms, which have focused on creating private wealth rather than expanding access to health care and education. Despite the country’s growing economy, 2.5 million Indian children die annually, accounting for one out of every five child deaths worldwide; and facilities for primary education have collapsed in large parts of the country.
    PL] But a lot of this is coming to light due to media activism and things are being done.

    :: the official literacy rate of 61 percent includes many who can barely write their names
    PL] What is wrong with that? Being literate is defined is you being able to sign your name.

    :: Feeding on the resentment of those left behind by the urban-oriented economic growth, communist insurgencies (unrelated to India’s parliamentary communist parties) have erupted in some of the most populous and poorest parts of north and central India. The Indian government no longer effectively controls many of the districts where communists battle landlords and police, imposing a harsh form of justice on a largely hapless rural population.
    PL] True.

    :: No labor-intensive manufacturing boom of the kind that powered the economic growth of almost every developed and developing country in the world has yet occurred in India. Unlike China, India still imports more than it exports. This means that as 70 million more people enter the work force in the next five years, most of them without the skills required for the new economy, unemployment and inequality could provoke even more social instability than they have already.
    PL] I cannot comment on the numbers but as for social instability, it goes up and down and predicting a war of the classes is being alarmist.

    :: For decades now, India’s underprivileged have used elections to register their protests against joblessness, inequality and corruption. In the 2004 general elections, they voted out a central government that claimed that India was “shining,” bewildering not only most foreign journalists but also those in India who had predicted an easy victory for the ruling coalition.
    PL] There is apathy, cynicism and a lack of political sensibility amongst the Indian middle class to political processes. The middle class did not vote which is why that government lost. However, this is changing. See the right to information campaign.

    :: Among the politicians whom voters rejected was Chandrababu Naidu, the technocratic chief minister of one of India’s poorest states, whose forward-sounding policies, like providing Internet access to villages, prompted Time magazine to declare him “South Asian of The Year” and a “beacon of hope.”
    PL] Votes especially in rural India are not truly independent. A lot of parties canvas rural voters by giving gifts just before election. The voters are happy so the parties get the vote. This is a problem of a lack of education and independent thinking. This has plagued India for quite some time and is government independent. I suspect all governments have used this lack of independent thinking to win votes.

    :: But the anti-India insurgency in Kashmir, which has claimed some 80,000 lives in the last decade and a half, and the strength of violent communist militants across India, hint that regular elections may not be enough to contain the frustration and rage of millions of have-nots, or to shield them from the temptations of religious and ideological extremism.
    PL] It is no longer a question of have nots. The people of Kashmir want peace and are tired of conflict. The insurgency is being fueled by outside militants. Lets say you are a villager. You have 5 children to support and the rest of your family is starving. Some one pays you rs. 900 to throw a grenade in a market? Do you say no? That Rs. 900 will prevent your children from dying perhaps. What moral compass do we use to judge such actions? Of course, why were you starving in the first place? It is a chicken and egg situation. There is no investment since the terrorists wont stop and the terrorists are able to function so effectively by exploiting the lack of basic things such as food.

    :: Many serious problems confront India. They are unlikely to be solved as long as the wealthy, both inside and outside the country, choose to believe their own complacent myths.
    PL] Agreed. Complacency is indeed a problem but with increased access to government and information this is changing.
