Boys, Girls and Science
Technology Notes, Vol 1, Issue 4: Machine learning.
- First, evolution to create the present set of species has taken millions and millions of years, a time frame most of us cannot fathom.
- Speciation (or the development of a new species by evolution) requires a separation between members of a species and a separation of their environments .
- Evolution is occurring even today: Why do mosquitoes become resistant to DDT? Why do we need newer and newer strains of antibiotics? Why indeed is the AIDS virus so successful at avoiding every medicine we throw at it? Well, the answer is just one - natural (or in this case, human) selection. When we spray DDT or take antibiotics, we target and kill most mosquitoes(bacteria) in the environment. However, the few that due to some mutation survive, being selected by human selection, have the upper hand in reproduction, and spread the immune gene throughout the population, making the entire population resistant.
- Evolution does not happen only by random events: It is indeed true that a hurricane blowing through a garage of aeroplane parts will not assemble a Boeing 747, and it is true that random mutations on their own will not lead to speciation. However, random mutation in combination with non-random natural selection, that selects the fittest, either by killing off the weak, or by having mates choose a particular trait in the other sex.
Have been reading too much evolution. I hope to start reading more Physics from now on. Keep visiting!
BTW, I know my "speed of time" hypothesis is wrong, and if it isn't, I take no credit for getting it right. It was just a random thought that popped into my head.
Congrats, Anil Kumble!

Nostalgia: the 80s
This took me on another nostalgic trip. To the times when the world was a lot more innocent than today. When a Ramayan would empty city roads, or when the only movies shown on TV were on Saturday and Sunday. The news ran everyday at 7:00 and 8:30 in the evening. Everyone saw the same programme, mostly on a black-and-white TV. Your TV was usually a Dyanora, or an ECTV, or a NELCO (which was mine). Families gathered around to watch a Buniyaad, or later, an Oshin. A 2-in-1 was a major purchase. Radios and TVs were taxed. I still remember the license my folks had taken, to own a RADIO - not a station!
In all this, my favourite TV serial was "Johnny Sokko and the Flying Robot" or "Giant Robot" as we knew it. This huge robot, controlled by a little kid, was so popular with us kids that we literally dropped everything - cricket bats, gillis, badminton rackets, chur-chand balls, marbles, even stones - to go watch this series. The next day, everyone would be doing the routine - the arms in front of the chest, then pointing upwards, followed by the "rap pa pa" tune, and flying away! Yeah, yeah, I know you want to see it too - here you go: http://www.youtube.com/watch?v=vY0e3aTj3pQ&feature=related
By today's standards, the graphics was crappy, the animation dodgy, and the story lines were like a three-year-old wrote it. Still, we loved it. It was every boy's dream - an adult who would do his bidding! :)

OneNote is all you need
Yep. Read it with the "One love is all you need" tune. Nope. I haven't become a fan of "Blue". And yep, OneNote is a Microsoft software which does all you need.
For sometime now, I've been cribbing about usability of Microsoft software, particularly once you take into account how much it costs you to own them. I also have a slew of drafts lined up for you, all criticizing various aspects of Microsoft software, from Vista to Visual Studio. I had earlier cribbed about tables in Word - how you have to pre-create them, and you cannot simply tab your way into creating them. I also cribbed about how you cannot mix content the way you like, how you cannot search into content (images) and so on.
Well, OneNote is here. And really, it is all you need. OneNote lets you put text, handwriting, images, music - and here is the differentiator - where ever you want. Really. And It Just Works! In addition, most content is searchable. Even your handwritten text, or printed text in images. And searchable. And it integrates with Outlook. And you can make sections, pages and the like, as you need. And you have a shortcut in Windows that pops it up for you to take notes when your idea ticker starts to work. And you can tag things, make items in OneNote become Outlook reminders, and in short, do everything you need.
Try it out today - http://office.microsoft.com/en-us/onenote/default.aspx?ofcresset=1. This is one software, I'll bet, that will win, well, your mind!

A good read. Although at 700+ pages, it is quite long.

More on India@60
One reason why people of different religions, languages and castes live together in India is because your primary identity can be anything while you can still be an Indian. Consider the case of Pakistan, that split over language or Sri Lanka that is fighting an ethnic conflict whose roots are in language. Now, Tamils and Bengalis are in India. Why is it that they don't want (at least a majority of them don't want) a homeland carved out of India?
It is because the aforesaid countries supressed those languages, discriminated against those who speak those languages - all in the name of national unity. If speaking Urdu became the "Tabbott test" of being a Pakistani, where would all the Bangla-speaking citizens go? If being a Muslim is the definition of being a Pakistani, where can all the non-Muslims go?
When the founding fathers of India rejected the idea of India being a Hindi-speaking, Hindu Pakistan, they knew what they were doing. When Nehru conceded the demand for linguistic states, much against his ideas, he knew that Newton's third law of every action having an equal and opposite reaction applies as much to politics as it does to physics. Which is why, India is a country that does not react to the veils worn by Muslim women (like in France) or the Kirpans worn by the Sikhs. We have learnt that a truly secular state that values freedom of expression, also allows religious expression. We have learnt that the best way to make Hindi a link language is by not forcing it down people's throats (the UPSC for instance, conducts its exams in 18 languages, a record anywhere in the world), but by enriching Hindi with so much content (works of Gulzar, for instance), that it becomes irresistable. And we've learnt, sometimes painfully, that patriotism has nothing to do with being a Hindu, or speaking Hindi or even being religious. Consider for example, the case of our Lok Sabha speaker, who is a firm atheist. You don't find anyone contesting his patriotism!
What is the root of such tolerance? Or maybe tolerance isn't the right word - it should be acceptance. Why is India a country that accepts everyone? Is it a product of the freedom movement, or is it even more deeply rooted? I'll examine this in my coming posts.
Stay tuned.
If only women ruled the world...

What nice are you? Updated!
Ignoring nice: This is the American way. Everybody smiles at you - not just a : but a real :), but no one really cares. So, you may see a cute girl jogging on the road, smile at you and say "How you doin'?", but don't let it brighten your day, because before you can think of something nice to tell her, she is out of audio range.
Phony nice: Similar to ignoring nice. This is the nice that is put on by people putting you down, albeit softly. The lips are drawn into a smile, but the brain hasn't changed the tone of the voice - which is usually the giveaway.
Patronising nice: This is how some brilliant people respond to ideas suggested by lesser mortals. Their upbringing won't let them be harsh or rude, and at the same time they don't want to give credence to a remark made by someone who is clearly a lesser human being. So, they smile, nod, pretend to listen, and thank you for your comments, while their brains are trying to solve a completely unrelated NP-hard problem in polynomial time.
HR Nice: This is the easiest one to understand. One of the traits taught by every management school to every HR major, HR nicety is keeping a large smile on your face, saying "Hail Caesar" with a really sweet voice, while stabbing Caesar in the back. Beware of the HR smile. It usually means "I'm screwing you" or "I'm making you screw yourself". Note how the HR smile is never accompanied by a "no". You could call the HR person a jerk, a whatchagonnacallit, but he or she won't lose the smile. The one drawback of this smile is that it is universally employed, and therefore can be detected with the greatest ease, while putting up the smile facade expends enormous amounts of energy.
You know of any more? Post them in the comments section.
PS: While you are at it, try looking for an "updated" logo on the net. Some picture with the "Updated" text in it. It should expose a lot of the limitations of today's search engines :)

More Moron talk
One: have healthy respect for your workers and invest in their welfare.
Yeah, right - let's see...how many training programs does the government conduct that trains postmen to become something better? How many programs offer education to the gangmen of your municipal corporation. How many even train teachers, or for that matter, IAS officers? How many government buildings have ramps and toilets for the disabled - a bare minimum to give them dignity?
Two: corporate social responsibility should be defined within the framework of a corporate philosophy which factors the needs of the community and the regions in which a corporate entity functions.
Again, what about government social responsibility? Oh, as long as we keeping bellowing "aam aadmi" from the rooftops, that is taken care of.
Three: industry must be proactive in offering employment to the less privileged, at all levels of the job ladder.
No problems with this one.
Four: resist excessive remuneration to promoters and senior executives and discourage conspicuous consumption.
Five: invest in people and in their skills.
Like number 1. It's infact more than a coincidence that Moron was a teacher. Preach, but don't practise is his firm philosophy.
Six: desist from non-competitive behaviour.
Heh heh. Mandating roaming call rates in a competitive market is not non-competitive. Putting road-blocks to private investment in airports under the guise of stupid laws - well that is competitiveness at its best. Moron, JRD is no longer alive. And while people like Narayana Murthy and Azim Premji keep his flag flying high, it is up to your government to have a competition commission that works. Where is it?
Seven: invest in environment-friendly technologies.
Eight: promote enterprise and innovation, within firms and outside.
No qualms with this one.
Nine: fight corruption at all levels.
Look who is talking.
Ten: promote socially responsible media and finance socially responsible advertising.
Same as point 5 - about conspicuous consumption. Simply ridiculous.
All Moron is doing is lay the blame on someone else's doorstep. The doorstep he should lay the blame at is actually in 10, Raisina Hill, but unfortunately, that is akin to visiting a lioness whose lions are thirsting for his blood, and therefore you can expect to see more moronic speeches like this one in the times to come.

Growing up in socialist India - 1: Television
Now, my family was a middle-class one - which meant that my folks probably had enough money to send my brother and me to school, and they probably had spare cash for buying a bicycle, but it also meant that I had to go on hunger strikes to get a TV in the house. Yes, our first TV, installed on 24th June, 1984 was a result of my weeklong hunger strike (during which I got ample servings of non-food items). And what could you watch on it? Well, there was the eternal favourites - Mahabharat and Ramayan, and kids had He-Man, Giant Robot, and an assorted set of cartoons. Adults watched "Yeh jo hai zindagi", "Hum log" and "Buniyaad" - which to my mind were totally wierdo serials.
But what was unique to the socialist experience were films created by Films Division of India on national integration. Most of them (except those created by Louis Banks - Mile sur, and Bhaje sargam to name two) were crap. The animations sucked, the voice-overs were terrible, and each of them had this preachy tone that was so representative of the governments of that time.
Of all the serials I watched on the tube then, the one that still remains in memory is "Oshin". This must have been the most heart-rending serial I've ever seen.
Anyway, more info about such shows here: http://full2faltu.wordpress.com/?s=Woh+Bhuli+dastaan. Do write in about your favourites.
