comment What would be an appropriate algorithm to factorise numbers in the range of a few billion?
I'd say using isPrime is an overkill. Just doing n/=2 while n%2==0 and then starting i with 3 and then looping if (n%i==0) n/=i; else i+=2; is enough (well, it can be stopped once i*i > n).

comment What language/framework/workflow sets do you recomend for a small office?
And if you are going to do thing like Ericsson does (telephone switches that must work with lot of concurrent data and heal from failures) go for Erlang.

comment How should semi-agile team operate during management-imposed waterfall-like “testing phase”
Ok, not from scratch, but by treating old code as legacy and poisoned and instead of "fixing bugs" simply refactor and nothing more, using all methods that are used to work with legacy code, making it right in the process. The bosses can hear about "big fixing" if they need to, though it will be really just "development done right at last".

comment Why is it impossible to produce truly random numbers?
Are you really asking why you cannot produce truly random number on a deterministic device? Doesn't the question already include the answer?

comment Is Dijkstra's algorithm an appropriate solution to this signal routing problem?
@PeterTaylor: Would it matter if they were multiplicative? They have exact same semantics as additive (provided they are positive) by applying a logarithm. Or is it something more complicated behind it?

comment Is Dijkstra's algorithm an appropriate solution to this signal routing problem?
@PéterTörök: In that case, yes. Only the asker knows for sure. But when it is a tree, bfs is enough (and dead simple).

comment How did you pick up the art of solving real life problems? Can you shortcut the process?
@Maxood: Please, Smalltalk is not written with capital T. Thanx.
