Interview question #3

I came out with another interview question to find out the candidate's visualizing power:

The object is chessboard--you know it has black and white squares.
  1. How will you visualize the chessboard in terms of mathematical formula?
  2. How will you visualize/depict the same in PHP code?

Thanks lawrence krubner for your comments. Actually, I'll be expecting just two keywords: Matrix and two dimensional array; that's all. I don't expect any brilliant answer:-)

Madurai food Vs Nagercoil food

There's huge cry that Madurai idlis are best. Having stayed in Madurai for 7-years, I can give assurance that they're crap. Madurai foods (especially available in hotels) are of poor hygiene and poor in taste. But, I always like the people--they're friendly and helping. My favorite is always Azad Hotel's (Nagercoil, near Tower Junction) chicken kothu parotta . Nagercoil food like aviyal , samba (red) rice , etc are always good and healthy as they're cooked in coconut oil and with high hygiene--even in hotels.

Nisaptham Trust - Address and PAN for 80G

Today (July 31st) is the last day for filing income tax returns. Donations to charity and political parties are exempted for tax under Indian income tax clause 80G . When it comes to donations, World Vision India used to be my choice because of their professionalism and prompt communications. Of late, having heavily impressed by Nisaptham Blogger 's writings about his charity work, I thought of sending meager amount to his charity Nisaptham Trust. Unfortunately, when I sent that in March, it was not a pleasant experience. I had to randomly follow him through email and WhatsApp to get PAN of Nisaptham Trust; he shared that PAN details after 3-months. When I try filing returns yesterday, it was another shock; apart from PAN, I also need to furnish the charity address. I quickly searched through Google and there were no results about the address; I can only find its bank account details. Google's autocomplete suggestions hinted the possibility of such queries by others thou...
