If only Haskell would let me do type MTree t = Map t (MTree t) This version works though. data Tree t = Leaf | Node [(t, Tree t)]

I got the snake one, which changes as I resize the browser window. I was pleased to see somewhere along the snake was the elephant it had eaten.

For about $200, young Nevadans who face a statewide 13 percent jobless rate can hop a Greyhound bus to North Dakota, where they’ll find a welcome sign and a 3.3 percent rate. Why are young people not crossing borders? Because in addition

I'm not really surprised that the availability is still pretty low. Regular lecture-oriented courses don't have to deal with requirements like "there is only one room on campus where this course can meet," but this becomes a problem _very_

Some commenters seem to think the only reason to learn a bunch of languages is to have a bunch of tools ready to apply to whatever problem comes along next, and yes, it is difficult to know many languages well enough to do that. However, I

For the record, we use a similar trick on sphere-like surfaces, as latitude and longitude.

Pretty much anything can be considered as a "system," any aspect of it its "internal state," any aspect of it which can affect something else its "output," and any phenomenon that can affect it as "input" or "stimulus" (there is no need for

So what qualifies as an input? That which affects the system What qualifies as an action? Changes in the system's internal state or output How do you tell if some physical system, e.g. some biological system, contains 'inputs' and 'act

Racket doesn't have math-oriented types, AFAIK, even in Typed Racket As far as I know, it uses "machine-oriented" data representation when it can (sufficiently small integers, inexact numbers) and promotes to arbitrary-precision represent

How is a system informed by an input that 'carries information'? It processes the input to determine what actions to take next. What details is the system able to 'learn about' from that input/information? Some facility for conditional

What is it about a physical process that means it is performing computation? It transforms input to output -- some computation systems are just less powerful than others :-P People often think that Information Theory provides an answer,

Might I recommend adding the link to your HN profile's "about" section? It may be of interest to some folks here (at least, I don't think I've been able to go very long without seeing people here talk about economics).

Packman's scoring is based on collecting items and is not time dependent. The author does not bring completion time into this at all. He reduces (a still NP-complete subset of) Hamiltonicity to the question of whether a Pac-Man level can

I suspect many in the HN community are associated with the IEEE and ACM. You might want to consider adding these two orgs to the list. (Disclosure: I am an IEEE member and a past ACM member). Both these orgs have great digital libraries an

I really hope so. The notion that someone might be serious about the first one is rather depressing.

does it just require and adjustment of thinking to a new paradigm or is doing everything harder? Depends on how restrictive your language is. Scheme makes it a lot of things easy, e.g. a sequence of statements is often easy to express wit

since a large amount of programming is all about state and side effects IANA web developer, but... Doesn't web development typically put state into a database system instead of the scripts the server runs to generate the requested pages?

That's a rather different standard of right and wrong than you seem to support in your previous post.

Was assembly really the right tool for this either? It seems like the difficulty of translating Fortran to Pascal due to Fortran's lack of many of Pascal's higher-level features would still apply to assembly.

The typedef tuple strategy doesn't let you distinguish between types except by the types and ordering of their fields. If you later have a constructor for another ADT (or even the same one) which also takes two Float arguments, you end up w

Your iterate function as written relies on a top-level define feature, which pure lambda calculus lacks (motivating the use of fixed-point combinators).

I would argue that there's a big difference between "demystify how the text of your program changes the coloured lights on your screen" and "demystify why the text of your program changes the coloured lights on your screen". I agree, ther

I think I'd be more inclined to call this version a Church tarpit.
