Hacking new technology

Our team always used to hit the edge cases quickly... Some technologies might be there for years, but when we start hacking, we'll immediately come across a situation that might faced only by veterans. Our experience with Delphi (one of the coolest technologies), ASP.NET MVC, MonoRail/ASP.NET, iPhone/Android programming proved that. This time, with another new technology... fingers crossed...

"A to Z of C" in the book Cimple (ISBN 0070260982)

I was just searching "A to Z of C" in Google Books and found that the book Cimple written by Sasant K Rout has used our code. The irony is that the book was published by Tata McGraw-Hill , who rejected us in final stage stating that it wants us to get endorsement from any IIT professor, which we couldn't. (For the sake of record... IIT Bangalore was linking & supporting "A to Z of C" for long time once it's published over the net; see old IIT page from web.archives.org ) It's just another incident to prove that success isn't a measurable unit; even failed attempts can be appreciated in any other forms.

Interview question #1

Since I have been asked to interview experienced PHP programmers, I was preparing few interview questions. I came to know, most of the people ask questions found in the Internet; most of them are like "What is the function used to connect MySQL DB in PHP". Personally, I don't like these types of questions; I'd thought the person must apply ideas what he was taught in colleges--finally I came out with one question: A product vendor has Quantity Vs. Price data like 1 -> Rs. 50 2 -> Rs. 95 3 -> Rs. 140 .... like upto 1 million data. He wants a system, which gives the price when the quantity is provided. For example, if you provide the quantity value as 2, then it should provide Rs. 95. How this system can be designed? As expected, all the people said about using database tables and quering on quantity. I have asked them to find out a system which doesn't use databases--provided the accuracy of the system may not be 100%--it may give at least 90% ac...

Interview question #2

This is related to PHP's array . An array has number of elements. All elements are integers and unique, which means there is no repetitive integers. (e.g.) $foo = array(7, 5, 9, 13, 2, 8); You have to sort the array, provided: You should scan the elements only once. You're not allowed to compare the elements when sorting. (i.e., you're not supposed to use any comparison operators) Sorted resultant array may not be the source array. How will you do that?
