Don't get old
Take a vacation before the world ends.
See a lava lake.
Watch Sachin's 100th 100.
Burn my underwear in protest of unfair treatment of humanity
Escape the 2012 apocalypse (of course with a pretty girl. Who wants to live alone on an island?)
Repopulate the earth.

Trust: In Relationships and In Computer Science and Economics
Trust is something we use everyday in our life without explicitly thinking about it. In simplest of terms, trust is that ambiguous quantity you refer to when you are doing a transaction with someone who you have insufficient information about.
This definition though feels inadequate when you take relationships into account, since you know the person you are dealing with. Thus a more fine grained definition is needed. Point to note here though is that even in relationships, you know the person and that assures you to trust them however you are still unsure about the outcome of your transaction. Thus the new definition though different needs to have a common thread with the previous definition.
So we define two separate definitions of trust, computational trust and personal trust, the names are more or less self explanatory. The difference between the two trusts as defined by researchers is that while a breach of trust in computational trust invokes a penalty, in personal trust it is forgiven and forgotten. Which is true since this is what relationships are built upon in an imperfect world. However, it should be noted that even in personal trust, breach of trust over and over again, reduces it. This implies that there should be a threshold in personal trust after which it would begin to decline. The threshold in this case would depend upon the original level of trust between the two parties.
In computer science the idea of computational trust may suffice in most cases, however this isn't suitable in economics where relationships are built over a long period of transaction between the service provider and the client. A personal trust with a dynamic threshold would be better suited in such scenarios despite the parties involved being software agents.

New Look
Just changed the look of the blog, the old one was ..well old. Needed a fresh look, a minimalistic design which isn't too dark or in your face and here it is.

Caffeine and Memory
Just read a very interesting paper on caffeine and how it affects our memory. Specially interesting since a number of us consume caffeine the night before an exam to mug things up or in other such instances when you have to be up all night. You probably already know too much of this stuff will make you nervy and will be no good but is it even fine to take in moderation. The answer suggested by this paper would be yes and no.
Effects of caffeine is influenced by more factors than you can think of including the time of the day, your personality, what kind of information you want to process and you gender for example. Might seem contrary but in general caffeine is better for long term memory tasks than the short term ones. Authors of this paper carried out a survey and experiment and the results show that while moderate amount of caffeine facilitated short term memory in females, contrary to popular perception it actually impaired the short term memory in males. However a higher dose of caffeine is good for both sexes.
Confused? Let's just say the paper suggests, either take no caffeine or if you have to take it take lot of it but then again not so much so as to make you restless and nervous.

It's a New Year Folks
Didn't realize it was a new year until the first day was over and somebody called me up. Well for the first time I did celebrate the new year and during the celebrations forgot why we were doing it. Unlike last few years haven't retrospected and made any list ....maybe sometime later ... haven't got any alone time yet.
One thing I wish though is that Sachin starts this year with a century again also that I finish my PhD. At least one of them is possible.
Well Hapy New Year
