Try to solve this

Three people enter the room, each with a hat on their head. There are two colors of hats: red and blue; they are assigned randomly. Each person can see the hats of the two other people, but they can't see their own hats. Each person can either try to guess the color of their own hat or pass. All three do it simultaneously, so there is no way to base their guesses on the guesses of others. If nobody guesses incorrectly and at least one person guesses correctly, they all share a big prize. Otherwise they all lose.

One more thing: before the contest, the three people have a meeting during which they decide their strategy. What is the best strategy?

Total time to solve this puzzle is 15 days. After fifteen days you can check this blog to get the correct answer.

Google API has a BUG

Recently i was checking Google federated login API implementation with Zoho. While using Google login facility with Zoho I encountered a BIG error. I logged in to Zoho with "Sign in using Google" facility. After using it when i logged out of Zoho, I found that i was still logged in in my Google account. Looks like this api has logged me in my Google account also in the background. This is a BIG bug in a country like India where maximum internet users use public places for internet access.

10% Innovation

I am really impressed by google's 20% innovation strategy. It gives space to an individual programmer to innovate and show his skills in his area or topic of choice. I will highly reccomend to new startup to adopt 10% innovation strategy. This will give startup a good amount of time to work on their project and simultanously give programmer also a fair amount of time to work for their choice of topic. Always remember that if google wouldn't have adopted this then they couldn't have develope adsense, google suggest and orkut like products. These products require efforts similar a full company product.

An Indian startup company

In an old essay Paul grahm has written three basic requirements for a successful startup. 1-to start with good people 2- to make something customers actually want 3- to spend as little money as possible. Lets analyse these three points in Indian context. Very first point is a problem in India. Who is good people ? If you want a real good software engineer then you have only one option in India is to hire peoplw from IIT's. But seeing salary centric work culture it will be a huge pressure on small pocket of a startup. So what is the alternative ? this the point where most the startup fail in India. They go for intermediate level of programmers ( 1-2 year exp) came out from horrable knowledge mines ( read new breed of engineering collages). Solution - Go for freshers and harnesh their infinte capacity to work on your dream project. The second point is well known fact whether you are starting a comapny or your PHD. You need to know which existing problem you are going to solve and how
