Management jobs

Something that I don't like about Management jobs and people who do such jobs. You can't fix a Hi-Funda name for every trivial thing that you do. It's not you can't, but sounds idiotic to me.

Bibtex

This seems to be a very good database for maintaining a record of the papers that one has read. I can introduce addtitional fields without disturbing the way in which the references will be displayed in Latex. I am only about 40-45 papers old, and I am already feeling a need for such a thing. I just don't understand how my profs work without this. Mama (my prof) said he used to attach notes to the papers using Gem-clips. But in this era, where one cannot afford to print all papers, this is surely necessary. I have written a small one liner in awk to convert the citations from given format of comma separated values to the bibtex format. (Has a lot of problems for instance the code wont work when multiple authors are separated by commas) awk 'BEGIN {FS="," ; RS="\n" ; x = 1} ; {print "@article{"x","} { print "title = {"$1"}," } {print "author = {"$2 " },"} {print "journal = {"$3" },"} {print "volume = {"$4" },"} {print "number = {"$5 "}," } {print "year = {"$6 " },"} {print "pages = {"$7 "}," } {print "}"} {x = x + 1} ' file.txt >> output_file.bib

All I can say is this works. It may look very untidy at the moment. You can change the Field splitter, Record splitter. You can change the order in which the entries appear. And ya most important of all, you can change the order in which the entries are read from the file. This is the most uselful part since all the citations from a particular source look the same. All you need to do is get the citations from that particular source as a text file and then allow awk to work on it after suitable modifications of the above code. The keys are numbered numerically from 1 to the last entry. You can (rather should) rename it later.

There are softwares like Pybliographer, Kbibtex, Jabref (Java based for Windows users) which can be used to update the database, write notes on selected papers for future reference, link them to the pdf's that you have for immediate reference, and most important of all export your references in formats like pdf, html, xml and so on

Springer and it's Book Series

Springer Verlag or Springer is undoubtedly the best publishing house that I have seen so far, atleast as regards Engineering and Applied Mathematics. It's just too good. I look at any "Yellow" book now a days with a lot of respect. One nice concept that they have is the concept of a "Series" on a given topic. A casual search on the series with the keyword "Computational" yielded me 56 series, 2230 books& CD-ROMS and around 107 journals. Of course I am interested only in CFD for the moment. So I have "bookmarked" only the relevant books as I considered it. My bookmarks.html is available in my website. Springer Series in Compuational Physics Springer Series in Computational Mathematics The above series are my favourites. However a large number of issues seem to be missing from the first one. (infact only the two volumes by Flectcher are listed there) The famous book by Canuto, Hussaini et al on "Spectral methods in Fluid Dynamics" belonged to this series. Another blog on some of the other books in the other field that I am interested in "Asymptotics and Boundary Layer theory" later.

Life at IIT

This is in reply to a discussion at Nanopolitan. Nope, IIT is not like school. It's not about being regular to class, taking down notes and all that stuff. It's about discovering your true area of interest. Not all (infact I can confidently say most) join Computer Science Engg or Electical Engg because they love it. You have an exposure to so many new areas. I am a student of Aerospace Enng at IIT Madras and apart from Aerospace I am also interested in Control Theory, Digital systems, Analog circuits, Operations Research, Listening to physics lectures from my friend Aswin on General Relativity, Cosmology, Quantum mechanics and anything related to physics, Differential Equations and Asymptotic analysis in Mathematics, Astronomy (infact we have an active Astronomy club) Open Source Software (yes I run Debian GNU Linux on my computer), Politics and the list goes on. All this just for the fun of it. This is one place where you have academic freedom like no other place. No worries about your future. Read what you feel like reading. Your CGPA is not everything. People went on to do a Ph.D in Political Sciences after doing their B.Tech in Metallurgical Engineering from here. Many people get into Physics, Management, IT, Economics etc. It's all about discovering your true area of interest. Some people miss that opportunity and realise it later.

Test for wardenship at IIT Madras

http://www.iitmadras.org/corner/2005/sep07/ Prof. Devendra Jalihal seems to be an interesting character. I am not able to stop laughing, seeing his "options" even after reading them over and over again. Godavari must be really gifted to have such a warden. Not that my warden Prof. G.Srinivasan is bad. He is really good. But I haven't seen him crack jokes like this.

The Indian Education system

It is nothing short of a miracle that modern methods of instruction have not yet entirely strangled the holy curiousity of inquiry; for what this delicate little plant needs more than anything, besides stimulation, is freedom. -- Einstein Well that may not have been said by Einstein, but it doesn't matter. I have always had a problem with these articles on the current education system. One guy in his article would point out the problems and faults that it has. The other guy would say how his daughter went through the stress before and after her X th board exams. What's the point in saying "Ya, there's a problem" all the time. Of late the articles turned to giving suggestions. But even them, they weren't concrete. Initially I liked reading such articles. Then I got bored. It is just like Politics you know. Saying the same thing in a million different ways. What does Bush do today. Keeps saying terrorism everywhere he goes. I formed the impression that nothing is going to change, atleast in the near future. My idea is that, the current system of education is basically to enhance literacy. No more. This system is not structured in such a way that an artist or a designer or a historian or a journalist would stand out in a crowd. And ya may be mathematicians would stand out, but even that is a rarity. Seriously I don't see any other reason why I am in IIT. That I got really interested in Aerospace is another matter, but with a good system of education who knows what I would be doing now. So it isn't worth much more than helping you develop rote memory. Though education boards are trying to change it, there seems to be a lot of inertia. The problem will obviously not be with the students, but with the teachers. I recently learnt that Kerala has introduced a radically new system of education at the primary level. The following articles are pretty good. Though the one by the CPI(M) may have political aims, it's pretty good otherwise. http://www.flonnet.com/fl1615/16150880.htm http://www.indiatogether.org/2004/may/edu-grading.htm http://www.pr.com/press-release/1128 I never thought it would come so soon. Though detecting artists, designers, historians, journalists may still be difficult, this is a welcome change.

"Is this going to work? You are supposed to teach 20 to 25 children and there is double that number in my class. I am over 40, and they expect me to play 'aana' (elephant) and the 'frog in the puddle' before a group of second standard children!"

- Teacher to headmistress at a government primary school, in the presence of this correspondent.

But such statements fighten me. I just hope the teachers don't ensure that poor results are the outcome to change back to the old system. And that the system goes through the initial inertia it might face.

General notion of the US in Indian households

My mother told me that my friend, who is an year senior to me, had gone to the US very recently to pursue higher studies. It seems that his mother told my mother that he did not study as "hard" as I did during his +1 and +2, but still ended up going to the US, and hence I need not have studied "hard". This shows that the notion in her mind is that going to US is the ultimate aim of every student and that if you are able to achieve it by simpler means then it is not worth putting in more effort. It was a similar response that I recieved my from my mother's elder sister, having "sent" both her sons to the US, when she came to know that I got an admission in IIT Madras. Even more aggressive was the response when I told her that me going to the US or any other country would depend on the field that I am going to specialise in and that if there are good professors in India who can guide me further in that field in Universities that have the required facilities, then the US or any other country would only be a secondary option for me. By saying this I presume that the very reason any body wants to pursue higher studies in the US, should be because there are not many colleges and Universities in India that can boast of facilities that are comparable to the ones that US Universities have in their field. There is nothing wrong in going abroad for higher studies if you stand to gain by education there and you help either "SCIENCE" or "INDIA" grow by doing it. My friend TJ's comments on this is another way of looking at it (will link it in another few days). But "Going to the US" should defy not be anybody's ultimate aim. This mindset of my friend's mother is, I think, prevalent among the majority of the population who's sons or daughters are in that age group. (The point is that I was awake on one particular night till about 2 a.m or so and his mother saw me "studying" through the window, and that's it, my mother was considered to be forcing me to study at odd times and that she was "torturing" me. Little did she realise that I was doing nothing more than writing an assignment to be submitted the next day at school and that I had slept for three hours as soon as I came from school)

Archanas at temples - Status show off or Belief in God

I some how feel the Archanas in the Temples today are more of a status (mostly economic) show-off, rather than belief in God. I am not debating about whether God exists or not. Whenever I go to temples (which is a rarity and so my entire statement may be wrong) , I find that the talk among women is mostly about what sarees they wore or what necklaces they wear, and among men it is about where their son or daughter has gone for higher studies or their place of work. What is more important is people talking at home about the kind of "Archanas" or "Vadamala sevai's" that the other family did and that they should also do it as soon as possible. I have overheard this in many families (atleast ten including my own). And I live in Nanganallur, which is regarded as a temple town. Is this is a status-show off or are people foolish enough to believe that they are serving "God" by doing such things. And your status in temples is judged by the amount which you tip the pujari there everytime. It is generally in the hotels that we hear of such things. Not many actually notice these things. This brings into light another question. By how many percentage points can literacy in India be increased if money spent on such things, is inturn spent on sponsoring a child's education. I say that the money can go through all corruption, bribery and all that stuff and still literacy in India can be imporoved by fifty percent.

The Hindu : Metro Plus Chennai : Small acts of blindness

http://www.hindu.com/mp/2005/09/05/stories/2005090500250100.htm This article really brings out the daily acts of kindness which are well within our reach but what we fail to do. This is true atleast with me. I realised that I don't know the name of my Security and the guy who delivers my Newspaper. I had better find that out soon.

India needs energy, and the US

http://www.rediff.com/news/2005/sep/02sg.htm A very good article. I find it amusing that when the country is ridden with so many internal problems of Caste, Religion, Corruption, Literacy the higher officials find time to actually go behind strategic interests in the region. I am not saying that what they are doing is wrong, but that they are doing a great job. It is difficult to do a good job of both at the same time. But afterall that is what stragetists and diplomats are meant to do. I would be very happy if they just brushed aside the US warnings and cared only about security of the gasline in Pakistan. It wouldn't be a very good policy to follow this, but still I have my own "hopes"

India mocks at the US

However others might consider, I see it that India is mocking at the US by pledging $5mn dollars to the US Red Cross reilef. Way to go India!!!!!!!!!! http://in.rediff.com/news/2005/sep/03katrina.htm On the other hand the same money could have spent wisely on Primary Education and all the other pressing concerns of India.

How to establish a scientific theory

I found this interesting blog on the above topic. http://chutneyspears.blogspot.com/2005/08/how-to-establish-scientific-theory.html An interesting read.

Line up at IIT, entrance exam to get simpler - The Economic Times

http://economictimes.indiatimes.com/articleshow/msid-1211896,curpg-2.cms This is real bad stuff. I guess the media is just hyping up the actual scene. Nobody would like to see the standards of IIT's to be reduced. They could base it on 12th syllabus, but still make it tough. I don't understand the problem with the current setup. May be the poor aren't able to compete due to this unfair competition. Whatever move the Govt makes, let it be a wise one.

Chaltha Hai Attitude and India's development

This is in response (Not a reply, but I was enthused to write this by seeing his blog) to my friend Kumar's post on the ways in which an Indian citizen can help his/her coutry. The educated people have a lot more responsibility on their shoulders as compared to the illiterate ones. Those belonging to the former category should lose this "Chaltha Hai" attitude and those belonging to the latter should switch over the former category. The concepts of compassion and mercy should be thrown away when it comes to business. This is the main reason India is found lacking when it comes to quality. The idea to excel in whatever you do and always want the best must be developed in every individual. When I call up my cable operator that my cable is cut, he just replies, "Yes, It has been cut, What can we do?" The newspaper guy "Sir, I had some personal problems. This will not happen on most days, But I cannot assure you that it won't happen" . And my parents tell me "That's how it'll be. What can he do , Paavam" It is this Paavam attitude that I want people to get rid of when it comes to business. How do I care if he falls into a pit while delivering newspaper or while repairing the cable. All that I know is I pay him some amount for doing something, and that he should do it. That's all. That's the way it should be ideally (that's according to me). It's a similar story in the govt organizations. So, people do not take up responsibilities. Whether it comes to keeping your time, delivering newspaper, or whatever. I have heard that doctors abroad have a lot of responsibility when it comes to the treatment of their patients. Just one misjudgement and their career as a doctor is gone. To give an example that India is indeed changing in this direction is the Airtel ad that I saw recently. You don't get your phone repaired within four hours of registering your complaint, you pay a 100 bucks less in your next bill. May have a lot of clauses, but still this seems to be the right direction in which India will have to move to achieve it's dream of being a developed nation. For our elders, Indian products have always been inferior when compared to "foreign goods". Precisely the reason why one can see so many "Foreign goods" shops here. They are apparently never out of business. This frame of mind has carried over to the later generations as well. Such a frame of mind is bad, but it didn't have any repurcussions as long as our country's economy was protected. In todays world of open markets (unless you have the power to dictate terms and remain a closed economy), one has to match world standards when it comes to quality to even be in the race for the top. Otherwise you simply DIE. That's it. The law of nature "survival of the fittest" holds here. The "Chaltha Hai" attitude again comes to the Foray here. Quality is not delivered because it is not expected. Tell me a customer who demands a car that runs for 50 years without any problems. The marketing manager will just ridicule you if you ask him this. It is not that such cars do not exist (e.g Mercedes Benz). Such quality is just not expected and hence not delivered. My view is that only when concepts like "Customer is the King" "Quality and then Price" come into business and the "Chaltha Hai" attitude is totally abolished will India realise it's dream. These are apart from the things that my friend put in like abolition of religion and religion based prejudices etc.

IIT Madras, Saarang and TRASH

My views on Saarang were amply reflected in today's article in the Hindu regarding how much of trash it generates. 3.5 tonnes!!!!!!!!!!!!. Read the entire article here. http://www.hindu.com/2005/08/15/stories/2005081515770500.htm I know it is shameful to talk such things about my own institute, but really can't help it.

India - US Nuclear deal

I found these Rediff articles particularly good. They are interviews of Former Deputy NSA Satish Chandra. The US has not fully delivered - http://www.rediff.com/news/2005/aug/11inter1.htm World doesn't know how many bombs we have - http://in.rediff.com/news/2005/aug/12inter1.htm I am very bad at remembering names. Let's see if I start to remember a few of these names by blogging.

Astrology and Science

Tell me one theory in Science where the exact logic behind it is fully known. Right from our birth we go through various stages where we learn various theories. We satisfy ourselves by saying that we have understood the logic behind it. But if we keep questioning some points in that theory then it boils down to saying that "That is a fact" and there is no more explanation. So basically, we evolve through various degrees of logic before we finally come to a stand still and then there is no more explanation. We stand to accept that as a fact (atleast for a period of time until some one digs deeper) Astrology is not much different. My friend Aswin says that the astrologers use very old data. Accepted, their data is outdated. Let their predictions be wrong. So that means that, the usage of the same methods today is wrong. But how can that totally refute the very basics of Astrology. And one more thing, people didn't make laws for astrology and then leave it there. That too was developed as a Science. The conventions were different those days and everything was referred to as a "God". There were people who constantly worked on it increasing it's predictive capabilities. They didn't sit dumb. By they I refer to the various scholars of the yesteryears. Astrology didn't develop in India alone. The science simultaneously and independently (or so I know) developed elsewhere as well. But the principles of prediction are so similar. How do we account for that. I learnt some principles of Astrology without questioning it's fundamentals. I was wrong in that. But there is so much of Science and Mathematics in it. The age-old principle of teaching was "You believe what the Teacher says, then you question it and learn more" or so I believe. The principles of Prediction are so vague and loose that it is not correct to base the predictions on only one factor. You can't relate predictions to one or even a hundred factors and get some statistical data from it saying "this is no better than chance" I wouldn't read or believe any of those. When you question those principles it is equivalent to questioning a Physicist "What do you think is the grand Unfied theory today?" Today's Science is not enough to check the validity of astrological predictions. That doesn't mean that you don't question it. But the fact remains that you can't get answers which is so for many scientific problems. Another point that I would like to make is about those weekly daily or yearly predictions. I really tell you. That is just not Astrology. Stop quoting them as examples where Astrology has failed. Today, Astrology has gone into the hands of wrong people and they are exploiting it to their benefits. Say there are 12 Billion people on earth. How can a billion people have the same predictions. Just doesn't make sense. All these sciences or so called "sciences" of astrology, Vaasthu Shaastra and so many more are as far as we know very very vague. As far as I believe we are not able to accept it because of the circumstances under which we have grown. I am not able to answer anybody who at the end of a very long fight asks me "O.K tell me one guy who always predicts correctly" There are no Astrologers like Physicists or Mathematicians. That, there is so much of Science in Astrology or that it developed simultaneoulsy elsewhere or that the principles are similar doesn't answer the question. But we must accept the fact that we do not know much about it, and unless somebody comes to know more about it, we (who don't know anything) shouldn't comment on it's capabilities.
