io:format("Node started successfully!").

I am using the erlang mode in Aquamacs.
The mode, by default, creates a new pane and buffer "*erlang*" when I hit C-C C-K to compile an erlang file. (as seen in the attached screen shot)

I do not think "C-x b" is applicable in this case…

Trying to learn Haskell. I am trying to write a simple function to remove a number from a list without using built-in function (delete...I think). For the sake of simplicity, let's assume that the input parameter is an Integer and the list is an Integer list. Here is the code I have, Please tell me…

I'm trying to use Haskells Data.Heap module, but I'm incapable of even using it with integers. The only heap I've been capable of using is "empty", which does not take any arguments.
Later on I'll figure out how to instance for my needs, but for now I'd be glad if I was even able to test it with…

There has been some intermingling of Scala and Haskell communities, and I have noticed now and then people commenting on stuff that's supposed to be easy in Haskell and hard and Scala. Less often (maybe because I read Scala questions, not Haskell ones), I see someone mentioning that something in Scala…

fibs :: [Int]
fibs = 0 : 1 : [ a + b | (a, b) <- zip fibs (tail fibs)]
This generates the Fibonacci sequence.
I understand the behaviour of the guards, of :, zip and tail, but I don't understand <-. What is it doing here?
