comment Why is 0 false?
Just to mention that Lua does not imply that "0" corresponds to false. luafaq.org/gotchas.html#T2

comment Scratch - why do schools teach students a language that is not used anywhere else?
@NimChimpsky No, the main categories of bricks are distinguishable by color and they can be tested. "To include children who are not able to write syntactically correct structures – nor read them, yet – visually grouped blocks can be tested by clicking on them and they can be easily replaced with different ones in order to re-mix, modify, and create new versions of projects." en.wikipedia.org/wiki/Scratch_%28programming_language%29 You are free to learn your kids a commonly used language, but I think Scratch is a valid approach.

@NimChimpsky You are implying that we are talking about western countries with a low literacy rate. However, Scratch is also used in developing countries like India. And yes, literacy is an issue and shall be addressed by providing adequate learning resources in regards of language as well as computer science sites.google.com/site/summerofscratch

comment Which programming language for text editing?
Suggesting PHP with its terribly bad unicode support? No way. No +1 from me.

comment dechex(4000) - Why is it not signed?
Additionally, no hexadecimal value is printed with the "0x" prefix in PHP (see eg. sprintf). us.php.net/manual/en/function.sprintf.php

comment finding the time complexity of the following program
@m0nhawk The comma only separate formulas from each other. More self-explanatory characters to separate formulas are probably ";" or newlines. I introduced spaces for clarification now.

Replace commas in formula with spaces.

comment finding the time complexity of the following program
@m0nhawk I don't get your point. According to your answer and the Wikipedia article: Multiplying two numbers [where the greater one is] n with m digits takes O(m^1.585) or O(log_10(n)^1.585) runtime. This is not about space complexity.

@rwong None, that's an error in my DFA. Thank you for pointing it out. I fixed it.
