Always read all articles with writers motivation/agenda in mind. this is why I like research / tech articles that are thoroughly backed by data or math!
- it is turning the number into a string of 1s 3 => 111 4 => 1111 and so on
- then trying to simulate divisibility test by trying to find perfect groups of '11' to simulate division by 2 failing which (that is the backtracking part) and trying find perfect groups of '111' to simulate division by 3 and so on...

I observed this when I was back in school using a simpler expression
i = 0;
i = i++;
the answer will be different in different compilers. I use this as an interview question ever since, not to get the right answer but to understand the candidates thought process in solving the problem and his/her understanding of operator precedence :-)
I dont know your level, for someone like me who studied mathematics years ago but not applied it for years, I found "In pursuit of unknown, 17 equations that changed world" by Ian Stewart very helpful. While it is not a detailed math book, it gave me enough pointers to refresh and prepared me to dive deeper through other material.
$40 mil revenue is largely from their products and services on the network management and element management side (called AdventNet). They are not exactly a typical startup.
I agree with the unrestricted donation part. My money went MSF primarily because they had a staff of more than 700 people before the earth quake struck and knew how to help the country.
Good analysis and I agree with you on using custdev as a tool in your tool kit rather than follow it like a religion. Another point, Steve always talks about shortcutting the custdev process if you happen to be the SME on the subject. If you know lot about what customers want in a area because you have experience in then you can skip portions of it.
