Why do system objects like nil, true or false have a fixed object id in Ruby. Also I tried printing out the object ids of numbers, they are the same and follow an odd number sequence pattern. Any explanation for this? [nil,true,false].each { |o| print o.object_id, ' '} 4 2 0 => [nil, true, false] >> (0..50).each { |i| print i.object_id...
I am used to work with MSVS 2008 and 2010 for some time now. I did some projects using C# and C++ but I am still a rookie. For my next project I have to develop using the PAWN language and would like to use MSVS as my IDE. I did some research on the subject but since PAWN is not that popular I didn't find any satisfying solution. My qu...
I've got to the section on operators in The Ruby Programming Language, and it's made me think about operator associativity. This isn't a Ruby question by the way - it applies to all languages. I know that operators have to associate one way or the other, and I can see why in some cases one way would be preferable to the other, but I'm s...
Of the object-oriented languages I know, pretty much all but C++ and Objective-C compile to bytecode running on some sort of virtual machine. Why have so many different languages settled on compiling to bytecode, as opposed to machine code? Is it possible in princible to have a high-level memory-managed OOP language that compiled to mach...
I recently graduated with a degree in Networking and Systems Administration, and I am currently waiting to start a job in that same field.

During school, I...

But now I'm getting into some work where I'll need to be developing interactive web-based interfaces, and I need to learn JavaScript. My problem is that all the resources I've found online for learning JavaScript seem to be ta...
When all you have is a pair of bolt cutters and a bottle of vodka, everything looks like the lock on the door of Wolf Blitzer's boathouse. (Replace that with a hammer and a nail if you don't read xkcd) I currently program Clojure, Python, Java and PHP, so I am familiar with the C and LISP syntax as well as the whitespace thing. I know i...

Possible Duplicate: Simplest language to make an interpreter for I'm wondering what the simplest programming languages are, excluding Basic and Brainf**k?

Mostly out of curiosity: Which languages that are not solely functional (I'm also interested in multi-paradigm languages - I know that Ocaml and F# are ML dialects with OO added, so they inherit the algebraic data types from ML) have algebraic data types (or something similar) and pattern matching? They can be kind-of emulated using enu...
I'm going to reveal my ignorance here, but in my defense, I'm an accounting major, and I've never taken a computer science class. I'm about to start a new project, and I'm considering using Python instead of PHP, even though I am much more adept with PHP, because I have heard that Python is a more powerful language. That got me wonderin...

I have been searching through the website looking for the best language for beginner game development. Many people say a C based language, others suggest Python.
