they'd already been programming for at least 10 years before making Armok AFAIK.

EDIT: in case confusion is had, they've been programming since childhood

Recursion never is the only solution. Looping and recursion are both, if I remember that right, Turing complete.

[miauw62]

I dont use recursion a lot, but it's nice to know. The other day I used it and it felt like a pretty elegant solution.

Also, complexity notation is actually really, really simple. N is your input size (this can be anything. most commonly it's an array size such as for sorts or the magnitude of a number such as for prime factorisation.), and the thing after O indicates how your running time scales with that size. (This can also be done for memory instead of size).

[Antsan]

Yeah, the notation is easy. The calculations can get pretty hairy, though.

Learn it as you need it works fine in most cases. It's also an easy way to get the motivation to learn. But like mathematics, you may not know when some method/technique would be actually useful unless you learn it in the first place. It really depends on what you specialise in. Game development is nice because there is a wealth of information available out there, presented in nice and easy to follow tutorials, so its a field where learning it as you go works quite well.

Yeah but that early programming experience was also on weird amateur game development, so it changes nothing about my statement.  His formal education wasn't in programming at all, it was in math.

[miauw62]

Well, math is better for programming than philosophy or something

[TheBiggerFish]

In other news, TFW you realize everything got screwed up because you changed the order of your method's parameters, but not those of the calling methods.  Whoops.

[Skyrunner]

And that's why you need typed languages!

[Putnam]

And that's why you need typed languages!

or just avoid changing method signatures

[itisnotlogical]

But some day, some how, you might have to change something you've already written.

[Rose]

Then you make sure you change the types, so nothing compiles until you've corrected everything.

[EnigmaticHat]

I think he was responding to Putman.

[miauw62]

I have lost literal days to a bug like that. But, to be fair, it was BYOND, and I was modifying code a caveman created before writing was invented.

This is why its good to have an IDE with a "search all" feature.  Or a small enough number of files you can ctrl + f them all in a timely manner.
