Regarding first-class functions in Scala, it is written in the book Programming by Scala: A function literal is compiled into a class that when instantiated at run-time is a function value. When there will be many first-class functions used in a program, will this affect the JVM's PermGen space? because instead of simple functi...

Here's the function: $count = count($info['level']); function displayInfo() { for ($i=0; $i<$count; $i++) { echo "[b]".$info['name'][$i]."[/b]\n\n" ."Level: ".$info['level'][$i] ."\nP...
Let's say I want to take the sin of 1 through 100 (in degrees). I come from a C background so my instinct is to loop 1 through 100 in a for loop (something I can do in Matlab). In a matrix/vector/array I would store sin(x) where x is the counter of the for loop. I cannot figure out how to do this in Matlab. Do I create a array like ...
Hey all, I'm trying to create a robust audio player in javascript (& jQuery). I know that there are other players out there, but I'd like to try creating my own (so please don't refer me to jquery plugins).

I'm hoping there is a way to define a type for a function in Scala. For example, say I want a function that takes two Ints and returns a Boolean, I could define a function that uses that like this: def checkInts(f: (Int,Int) => Boolean) = { // do stuff } Is there a way to define the type of f? Then I could do something like: def c...

I'm playing around with the openSSL library and it requires me to brush up on pointers, and I'm having difficulty. I have a objective-c method: -(unsigned char *)encryptTake1:(unsigned char *)input inputLength:(int)inLen outputLength:(int*)outLen; It takes some data, encrypts it and returns a pointer to the data and the length of the...
Hello All, Is there a way to get user-defined php functions, variables, constants from a php file?

I have a (common) situation where I am currently returning a result that is a mixed type, sometimes a boolean, sometimes an error message.
