Well, I think it's reasonably intuitive to think that way. It basically involves asking yourself the questions - "what types of values am I interested in?" "what types of results do I expect?" and finally "how do I get from input to outpu

It depends on the situation, but I generally think in terms of pure (recursive) functions and types. This then usually provides me with a reasonably quick mapping to my preferred languages (e.g. ML or Haskell), as well as providing a reaso

This sounds like a good rationale for increasing usage of domain-specific languages. I assume this is why software like Matlab and Mathematica (and even more domain-specific packages built on top of them) are very popular within many scien

I have no idea what about this you think would be 'elegant'. It's elegant in the same way that using computed offsets into raw memory is elegant in C, which is to say that it's inherently fragile, prone to very subtle bugs, and detrimental

Sigh. Must we? This kind of large-scale dynamic behaviour tends to go wrong even in languages that provide type-checking and sensible lexical scoping. In PHP it's basically just a recipe for the kinds of untouchable "black magic" code th

I think it serves a purpose very similar to "I am a member of your constituency" when writing to a congressperson in the US - basically saying "you should consider what I say because my relationship to you is _____".

Definitely horizontal. I have a basic algorithm for garbage collection though: When there is no more room for new stuff to be laid out (i.e., it would introduce structural unsoundness into the heaving mass that covers my desk), I sift thro

It's a petition to the Prime Minister of the United Kingdom, so Commonwealth status is unlikely to have any meaning, because he has nothing to do with the Commonwealth (except for happening to be the leader of a member country). However, wr

Thanks for that. So there is a commercial version of the IDE that basically has more features?

For instances like these, I would happily pay $x per minute to talk to a real person. A high call charge would prevent random crazies from calling (e.g. "why isn't my website top of the search rankings!?!?"), but would at least give the cha

So I've only looked in passing at Scala, but I've certainly heard first-hand from several people who are forced to code Java on a daily basis that they have managed to use Scala for bits of their system. They all claim that their lives got

The presence or absence of anonymous functions is the deciding factor in terribleness now? I guess that makes PHP non-terrible, right? (and yes, I'm being sarcastic)

The "missing the point" argument is a little bit easy. It's not that I don't understand OOP - I do, and I've done far too much of it. I understand it, and I reject it as a useful paradigm for any of the classes of program that I would lik

In kragen's defense, we do know each other (from the internet), and we argue about these sorts of things to no end. So there is a discernible reason, it's just probably not obvious to the casual observer :) All of these properties of functi

I have to step in here to defend "non-trivial". Perhaps it is abused as a term by the population at large, but I'm reasonably sure it has its roots in theoretical computer science and maths. It has a meaning that is distinct from "complex"
