Earthlings

February 25th, 2010

A week ago I watched this documentary called “Earthlings“. Since then I am deeply ashamed of myself, for several reasons. But the foremost of them is not having the enough intellectual curiosity to understand how things reach us – it could be food, electronics or jewellery.

Movies and documentaries influence me to the extent of changing my lifestyle. I am sure that any sensitive individual would change his/her lifestyle if he/she gets to know the way some of our habits and lifestyles are affecting the lives of other people and animals on this planet.

Planet Earth, Home, and 11th Hour had a deep impact on my contribution to carbon emissions. Since then I have been trying to minimise my carbon footprint.

Four years ago, movie “Blood Diamond” forced me to think and give up gold, diamond and other kinds of jewellery (I was never a jewellery person). I had a golden chain and ring for myself. I stopped wearing them and have not bought anything made of gold, silver, platinum or diamond since then.

Recent one has been “Earthings”. It questions some of my very habits which I am oblivious of, such as

  1. Using food derived from animals, including milk : I am an eggitarian. I was proud that I was not harming any animal. I was OK with eating egg because no-one was killing chicken to get the egg. Same is the case with dairy product. But I never knew how cows and chickens are treated to get milk and eggs from them. Worse is the case if you eat meat.
  2. Use of leather : I never wore fur. But I did buy two leather jackets from Palika Bazaar in Delhi. I have been wearing leather shoes, chappals and belts since school days. But the Indian cattle cater to the majority of the leather market and the way cows and other animals are treated for such products is just beyond imagination.
  3. Entertainment : Animals are abused by the entertainment industry just to keep us amused. Rodeo, bullfighting, derby, circus, zoos are all different ways of torturing animals to entertain humans.
  4. Pets: Now this industry is picking up. Animals are caged and ill-treated just for the sake of making money by selling the offspring to humans.
  5. Use of animals in the name of science: Many tests of various degrees are conducted on animals in the name of science. Pure science is just the opposite of it.

The documentary lucidly presents the above issues with good narration. It has made me challenge my own lifestyle. It has succeeded in convincing me that I need to change few of my habits.

I have decided to take up the biggest challenge of my life, so far, – becoming a vegan. I have decided to give up animal derivatives, wearing leather, visiting zoos etc. I cannot become a vegan in a day. To start with, I have stopped wearing leather and have started to consume less of milk products.

It is very daunting and feels like almost impossible to become a vegan since most of the Indian sweets and chocolates are made of milk. Though I have switched to black coffee and black tea, it is hard to give up milk and its products as they are very tempting. Curd rice is such an integral part of south Indian food. From past one week I am not eating curd rice. It is a big step for me. There were times when I had survived only on curd rice.

I am not complaining about the habits of others. When changing myself itself is a huge challenge, how can I ask others to change. Above all, things like these are matters related to self-realisation.

I have met few people who are vegans. They have imbibed a sense of confidence in me. It can be done. All it takes is – time, patience and determination. I will keep you all posted about my new adventure.

BTW, if you are looking for some resource on becoming a vegan, here is a good link to start with – http://sharan-india.org

How to Practice Morse Code?

January 7th, 2010

One of the challenges in getting a Grade I licence for HAM radio operation is – sending and receiving morse code. Sending is relatively easier. 12WPM is a little difficult indeed. But if you have a linux machine, you have awesome tools to practice morse code.

Go for cwcp - Cwcp is  a curses-based interactive Morse code tutor program. It allows menu selection from a number of sending modes, and also permits character sounding options, such as the tone pitch, and sending speed, to be varied from the keyboard using a full-screen user interface.

If you like x-window, go for xcwcp - Xcwcp is an X-based interactive Morse code tutor program. It lets you choose from a number of options for practice, including sending random characters, random words, and characters from the keyboard. It will also receive Morse code that you send using the keyboard or mouse as a Morse keyer, and display the characters it sees.

In Bangalore, HAM radio licence exams are held in the month of January, April, July and October.

Today’s Bangalore Mirror Article

December 21st, 2009

Today Bangalore Mirror came up with the article – Techie ReSolution where it wrote about six techies cycling to work on a daily basis. I just wanted to summarize few things here.

For me the year 2009 is ending with great satisfaction since I could cycle to work throughout the year. I am leaving for my own version of ‘Tour of Nilgiris’ on 25th. The year started with the absolute beauty of cycling and will culminate in cycling.

Please remember:

  1. Adopting cycling as your primary means of transport is not easy but not impossible either.
  2. Start with short distances – cycle for about 3km a day. In the beginning, 3km can take as long as 20 min. But it soon comes down to 10min.
  3. Start cycling to grocery store and nearby places. Cycle during weekends and gradually increase the distance.
  4. 5km is a very comfortable distance and it gets a bit difficult after 15km (one way). I have seen many people doing 20km oneway, after sufficient practice.
  5. First few days your body will pain. You also need to adjust your saddle properly and emphasize on good cycling postures.
  6. Traffic in Bangalore is not very cycle friendly. But if you keep a low profile on the roads, maintain a reasonable speed and stick to extreme left, you will do good.
  7. Traffic police and other vehicles in Bangalore have been very understanding, so far.
  8. Pollution could be a great negative. Choose interior roads. It could be a bit longer, but you will love the fresh air :) You can use masks, if needed.
  9. Street dogs are a menace at night. So ride slow, don’t get into a race with them. If needed, get down the bicycle and walk.
  10. Always use lights – Note that light is not important to see the road but to be seen by fellow motorists. Majority of the cycle accidents involve bad lighting systems.
  11. I encourage people to use a good helmet.
  12. In a period of 1-1.5 months, cycling will soak into your blood :)

Wish you all a Happy New Year and a year filled with new discoveries such as cycling.

Few changes

December 17th, 2009

I changed my hosting service provider from Lypha to iWeb. 10yr hosting is just 1.67$ per month. Comes to Rs.1,000 a year. Also, I shifted back to Wordpress. For a while I was working on Drupal. Drupal is too heavy for a blog. Because of all these changes, there are some issues with images and formatting.I will be fixing them over next few weeks. Please bear with me.

Dual SIM phones are the future

November 16th, 2009

The mobile service providers now have the greatest possible challenge ever – competing with the tariff. So do subscribers – choosing the best tariff and the widest coverage. Now both are possible with the help of dual SIM phones.

Recently MTS launched its operations in Karnataka. The tariff is so attractive that I shifted to a new technology – CDMA. But I now carry two phones – MTS for outgoing voice calls and Idea for SMS. This combination will help me get the money I invested on the new CDMA phone (which was 1.1k) in just 3 months.

Going forward, the best option is to buy handsets with multiple SIM support options. Karbonn KC555 is one good option, if you want dual GSM/GSM or GSM/CDMA option. Plan your tariff such that you can divide your STD, local and SMS between the two different networks and get the most out of money.

Another new challenge would be posed to the service providers when TRAI allows subscribers to retain the mobile number while switching the service providers. Many people stick to a service provider even though they may not be happy with the service for one reason – change of mobile number. This scenario is going to change very soon.

How to learn Mathematics

November 6th, 2009

Throughout my education, my focus was just on understanding problems for the sake of exams. I never pursued problems as an exercise to stimulate my mind and seek a path to find real solutions.

In last few years I have felt a pressing need to re-learn mathematics with a different perspective – look at Mathematics as set of ideas and not as set of formulae. I must admit that I am now in love with Mathematics. Same has happened with Physics too.

Here are few things you can do to understand Mathematics better.

  1. Get a good understanding of history of Mathematics. The Greek and Babylonian inventions, which took several centuries to mature, are covered in high schools. But if you understand the context, you will appreciate what a breakthrough that idea was when it was invented. Several problems lingered for few hundred years before getting solved. It took almost 2000 years for calculus to answer the questions of change and motion. So what is the most effective way to quickly learn history of Mathematics? – Watch “The Story of Mathematics” by “Marcus Du Sautoy”
  2. Get a good idea of the ideas. Yes. Mathematics is all about ideas. How did  they originate? A very enjoyable way of doing this is to read two books – “What is Mathematics” by Richard Courant, Herbert Robbins and Ian Stewart and Mathematics – From the birth of numbers, Jan Gullberg
  3. Start solving interesting problems. You can find many places on the net to do so. One example is – http://projecteuler.net/

Try this new path. I assure you that mathematics will never be your nightmare but favourite pastime.

Lost my 1TB Hard Disk

October 29th, 2009

Today my 1TB Seagate 7200rpm Barracuda hard drive crashed. It was a hardware failure. If you can detect the disc in the BIOS, you can use some or the other software to recover the data. If it does not get detected in the BIOS, there are options, but costly ones. The best part is, now Ubuntu 9.10 has a built-in utility to warn you against disc failure – Palimpsest. I ignored the warning :(

I lost close to 970GB worth of data. Many of my favourite documentaries, teaching company video courses, television series and TED videos are gone.

I was shattered. But not to the extent of getting depressed. I lost a camera worth 1.5lakhs on the road, last year. I am used to such losses now :)

But there was something else that really made me ignore my loss. This morning I was at St. John’s donating blood for my mother friends who has been diagnosed with blood cancer. When I met the family, I could see the loss they were anticipating in their eyes. I know that I always buy my camera back one day, download all the data on the internet and fill my hard disk again. But losing a family member is just huge. Certain things can never come back.

The Feyman Lectures on Physics and The book of Indian Butterfiles

October 24th, 2009

I must admit that I did not know about Richard Feynman till recently. I am ashamed to call myself a Physics buff. But if you love Physics, you should not miss buying “The Feynman Lectures on Physics” series.

The lecture series is a compilation of lectures delivered by Feynman at Caltech between 1961 and 63. There are audio recording of the lectures too. The Indian version is pretty cheap (published by Pearson eduction). The set of three books cost around Rs.700 after 20% discount.
ISBN Number: 9788131721698, 9788131721704 and 9788131721667

I also picked up a book on butterflies. Butterflies? Yes. Butterfiles. Many birders have been inspiring me and I am now fascinated with butterflies too. If you are too, then don’t miss “The Book of Indian Butterflies” published by Bombay Natural History Society. It costs Rs.1200 after 20% discount at Tata Book House, IISc, Bangalore. ISBN Number: 9780195696202

I now need to get the problem solving supplement for the Feynman lectures (ISBN – 9788131725559)

BTWIN Rockrider 5.3 – a Review

October 10th, 2009

It has been close to four months since I got my new Rockrider 5.3. Overall, I am happy with the bike.

The bike is smooth, disc brakes are helping me a lot on the muddy roads I have in my locality. I loved the shifters. They are very smooth and precise. Saddle is pretty comfortable. Frame is good. Front fork is awesome – 100mm with lockout. Handle bar grip could have been a little better.

The main problem thing which I experienced was – lower handle bar. Also, the distance between the seat-post and the stem is little more that a Trek or a Merida. This puts good amount of pressure on my forearms and my back bends considerably. I had backache problems for first few weeks. My brother, who also has a Rockrider 5.3, has backache issue. We spoke to the people at Decathlon about the low handle bar. It was not of any help. Recently on a bngbirds birding day, I met one other person with similar problem. Even Rockrider 5.2 has the same issue.

Disc brakes are not as great as I had thought of them to be. V-Brakes are much better than mechanical disc brakes (not hydraulic brakes). But the major advantage is, you can do without perfect truing of wheels and also not worry about muddy roads. In case of v-brakes, the mud gets between the brake shoe and the rim and wears it off.

The cycle does not come with front and rear reflectors. Decathlon should consider including these considering the safety of the rider. Even the wheels have only one reflector. The attached bell is not that great. Re-aligning the wheels to the disc brake pads is important. Sometimes the discs can brush the pads.

Decathlon mirrors are not good. Don’t go for them. Decathlon fenders are nice, much better than the Bontrager ones we had.

Rockrider Kenda tyres could have had a different tread design. Bontrager tyres on the Trek give you a very smooth feeling as compared to the Kenda tyres of RR.

Pedals are little flaky and the reflectors fell off within few days.

RR 5.3 is a very good value for the money if you are buying it directly from Decathlon for 20k. If you are planning to buy it from a retailer for 23k, I suggest you to go for a Merida or Trek.
