Keep running to stay at the same place…


The GPA race is as thrilling as GTA! Well, not quite. But it does give rise to interesting situations and diverse emotions. After all, in the current scheme of things, grading is relative. So all that matters is where you stand relative to your classmates.
Intuitively it might seem that the best way to handle this in the interest of the overall batch is to ensure that no one studies for the exams. However, can each student trust the others not to study? What if someone breaks the “agreed code” and studies secretly? Given the two situations that the others might study or may not study, it might seem to a random student that studying is the safer strategy. At least he won’t be left stranded at the lower end of the GPA spectrum and well, there is this chance of actually doing well in the exams! Now everyone might think this way and end up studying thereby eliminating any relative advantage of studying that any one might have. What we have is Prisoners’ Dilemma in the academic setting in a new multi-player avatar.
Can “collusion” be implemented to solve the problems arising out of, let me dare term it – Students’ Dilemma? The problems are many: How to monitor effort? How to design a “punishment” for detractors to deter them from “cheating” (which ironically, in this context means studying!)? How to ensure that a student doesn’t get mistakenly punished for doing well in the exam by chance or by sheer ability? And the questions continue…
Consider a hypothetical scenario where students to agree to spend a specific and significant amount of time in the common area everyday so everyone watches over the other. Students can choose to watch movies or play games and everyone gets to watch what the others are doing. This will leave a reduced time for any prospective “cheater” to study extra in his/her own time. Ideally the system should be monitored by a third party, but what option do we have in this case? The teachers supervising students to ensure they don’t study enough? This doesn’t seem to be a feasible idea.
Social ostracism can be a potential punishment, but the Chatur Ramalingams of the world wouldn’t care. And if one person “cheats” or defects this way, then others also have an increased incentive to study.
It seems that we are stuck with the best response strategy of putting in significant efforts in studying after all. And anyway, if we agree on studying being a means to learning and not merely grades then the equilibrium where everyone ends up studying a lot, isn’t at all undesirable.
So, get back to your books.
As Groucho Marx said, “Outside of a dog, a book is man's best friend. Inside of a dog it's too dark to read.”

"I would have loved to do it, but..."



How many times have you mentally cursed your project team member for not putting in the required effort? And how many times has the feeling been mutual? Well, there is no end to this argument as “effort” in most of the cases is not directly observable.
In general we can say that free riding happens in groups due to the presence of people whose pay-off matrices look somewhat like this:

Hence (goof-off, goof-off) seems to be the Nash equilibrium in such a situation. How do projects get done then? I’d say that’s due to the presence of members whose pay-off matrix looks different from this perhaps because of behavioural reasons. Those persons would perhaps derive “utility” out of moral, responsible behavior. However, designing a free-riding proof system will have to concern with the “problem children”, not the ethically high people. The solutions will either have to increase the pay-off for working hard or decrease the pay-offs for goofing off. Both can be approached by steps taken at
1            1. The group level itself amongst the members
2            2. Institutionalizing some mechanisms
1.  At the group level, before every project meeting, each one can be asked to come prepared with a write-up covering the problem issues and suggested solutions. The meeting can then be used to discuss and filter solutions rather than briefing the unprepared ones by the prepared ones. This will also ensure some sort of a peer pressure for everyone to put in some work.  Is this step alone sufficient? Perhaps not.
Hence, we have to look at an agreed protocol for all group projects:
2. At the closure of every project, there should be a peer-review of every group member and the report confidentially submitted to the Professor. This process should be officially implemented at the institute level. More than the actual content of the peer-feedback and resultant grades, the fact that every member knows he is going to be individually appraised, will make him/her more productive.
This is of course only one possible theoretical solution. How it plays out in real life will have a lot of other direct and contextual variables moderating the situation.

Of God, Failed Experiments and Rajnikant



God looked left, right, up and down, scratched his head and wondered what he could call the feeling he was getting. He hadn’t bathed in days or even tinkered with his iGod.
It used to be good. There was nothing he couldn’t do, nowhere he couldn’t go; he was unchallenged and unparalleled.  Then he realized that this specifically was the problem!
He was bored.  
Being God was so boring. No challenges, no butterflies in the stomach, no taste of success when everything you do succeeds. Yes, that’s what he was feeling: boredom. He needed to do something about it. He needed a challenge, something that even he couldn’t be sure to control. He took out his iGod and tapped on iCreate on the screen. A very friendly voice crackled into existence.
How are we doing today, Sir?
God spoke into iGod, still pre-occupied, “Hey Murphy, I am bored. Gotta do something worthwhile… else everything seems so easy… ”
Occupational hazard, Sir. You control time and space, every particle follows your whim…how can you have challenges?
“Precisely my question, Murphy... don’t bounce it back at me…”
Err... may I suggest a small experiment, Sir?
“Impress me!”
Okay, I can simulate coin tossing in my processor and make every particle do two different things based on the two outcomes, and keep going indefinitely… so you see, after 2 tosses we will have 4 possible states, after 3,8, after 10, 1024 and so on. We keep tossing for a long, long time and what we will have is a contraption which would not only be complex but also without any design or order in it.
God started keying in the commands to simulate infinite coin tossing as he spoke, “Interesting, but still, since we know the probabilities of heads and tails, the entire system is under some sort of a measure and control…”
Here’s the fun part, the probabilities of heads and tails might not be fixed at 50-50 in this case. They can be dynamically assigned to each toss on the basis of a new algorithm I wrote…
“Can I take a look at the algo?”
Murphy’s voice flickered a little, “Umm…. Let’s not spoil the surprise…  Once you are done with the simulation, I will add my algorithm to the system.
“Okay, where do we apply this new logic?” God ran his hands through his hair. He didn’t really have much hope from this experiment. Murphy had promised him many exciting experiments in the past, most of them all hype and no fun. The worst was a Reverse-Karaoke program which filled music behind anything devotional anyone would sing for God. Combined with a non-musical voice, that can be a recipe for auditory holocaust.
Murphy cleared his throat, “Remember the stress ball you used to squeeze whenever I turned on the Reverse Karaoke? It has turned into a blob of infinite mass concentrated to an infinitesimally small volume. We can just make it explode into a lot of particles and apply the governing algorithm…
God finished keying in the commands. The iGod screen buzzed as Murphy went through the code and added his bits of the algorithm.
“Well let’s do it”, God said, “but I hope this time your contraption works…or else I might have to reprogram you…”
Murphy let out a half-hearted laugh and made the giant screen on the front wall of God’s chamber come to life. A few advertisements later, the image of the ball flashed on the screen.
I call it the Big Bang!” declared Murphy pompously as he started counting down, “…3, 2, 1
“Boom!” went the ball into a zillion zillion pieces and the screen started plotting the paths taken by each piece. Within a few Godminutes galaxies, stars and planets could be seen as the debris started expanding at an ever increasing rate. Pieces combined and recombined and were giving rise to new patterns.
“This is fun.” God thought as now he could see self sustaining and evolving organisms originate in a blue planet orbiting a medium sized star.
“Not so fun.” he realized a few Godminutes later when we saw those organisms evolve into two-legged life forms who were intelligent enough to start developing their surroundings to suit themselves, but at the same time stupid enough to kill one another and start destroying the planetary resources.
“Murphy,” he said, “We have to fix this.” pointing at the screen as one bearded man was getting crucified for being nice to others and suggesting others do the same.
Can’t, Boss.” Murphy said, “We have no control over this. The algorithm is self-adjusting and self-controlling.
God was feeling exasperated, “You mean we have to just watch this roll-out in front of our eyes?” as a big bright mushroom cloud dazzled the screen on a location which was marked as Hiroshima.
Not really. You can take a break” Murphy spoke in a matter-of-fact voice “Go on a vacation.
God stared in disbelief as Murphy carried on “Trust me. This algorithm is fool proof and now I think I can tell you what it is...
God was listening silently as Murphy paused for maximum effect and then said, “The algo behind this experiment, dear God, is – ‘If things can go wrong, they will’. Every time there is a bird dropping on a newly washed suit, every time a piece of bread falls with the buttered side down, every time you miss a bus or every time an elevator gives you the miss, it is my algorithm at work. I have put Creation on Autopilot now. The universe, the planets and their inhabitants might seek meaning, deeper significance and spirituality to explain the random things that happen to them, but they’ll never know it’s our experiment that’s causing things to happen.
“Look, it’s a foolish experiment…” God tried to drive some sense into Murphy.
Yeah, Nice name…” Murphy replied “’LIFE’ we will call it. An acronym for Look It’s a Foolish Experiment. And it will be governed by chance and my algorithm which will henceforth be known as Murphy’s Law: ‘If things can go wrong, they will!’
Meanwhile, at one point on the screen, a few men drove an airplane into some tower while at a different point a bearded man was laughing his guts out at the news. God decided he had had enough. He tapped the iPack icon on his iGod as his collection of robes started neatly sliding into his Skybag as he looked one final time at the screen for some flicker of hope. Somewhere marked as Bombay a bearded, capped man tilted a microphone over his face and started howling one of the worst songs God had heard since a long time. Murphy proudly asked, “Isn’t he nice? I made him practice with my Reverse-Karaoke, the project that you had so disdainfully trashed.” 
Taking deep breaths God asked, “Murphy, is this a coup of sorts? Now that I am totally powerless and everything down there is ruled by, what do you call it, Murphy’s Law?”
No Boss,” Murphy’s voice was sincere, “I think it’s because I had jacked up our systems to my processor running the same algorithm a few Godminutes before you started cribbing about getting bored of being so powerful and tapped on iCreate. I had thought I would silently run the experiment and note down the results. But now as you see, one thing led to the other and now both down there and up here it is chance and the algorithm that are running things.
God tapped his iGod for the last time on an icon called iFly and docked the device on the wall. He picked up his Skybag as his personal transportation device phased in into existence. He eased into the cushion seats of his transporter and looked at the iGod screen one last time.
“Now with me gone, and your Law taking care of Creation, what will you do, Murphy?”
Oh I don’t know, Boss. May be I will sing.
“So long,” God hastily pressed a button in his device before Murphy could switch on the karaoke program and his device whizzed out of existence only to appear a few million Godlightyears away when he eased back into his seat and took a long, deep sigh.
“Oh my Rajnikant,” he mumbled.
Back in God’s castle, as Murphy busied himself with practicing the newest cacophonous tune, unseen to him, on a point marked Chennai on the giant screen a dark, moustached person looked up in the sky, swung his index finger in the air accompanied by a whipping sound and said, “Don’t worry, Bro! I am still there to fix things. Mind It!”

One Idea

I was reading an article today which talks about what a great move it was to bring democracy to this country. Giving the right to vote to the masses who were different in every way different from each other was a monuental effort, wasn't it?
I beg to differ.
I believe people should "earn" the right to vote and reaching the age of 18 shouldn't be the only criteria. There should be a comprehensive screening mechanism to find out the people who would vote for an idea or principle and not biriyani and desi tharra
Am I advocating inequality? I don't know. I don't care. I know I am advocating merit. That's what the country needs the most now.

Relay Shun Ships

Are they overhyped?
Are they merely viral behaviour?
Or tools to echo someone's ego?
