Something like: deck = Card.deck.shuffle! deck.each do |card| @players.NEXTELEMENT.hand << card end wh...
Take, for example, the VSTi Triforce, by Tweakbench. When loaded up in any VST host on the market, it allows the host to send a (presumably MIDI) signal to the VSTi. The VSTi will then process that signal and output synthesized audio as created by a software instrument within the VSTi. For example, sending an A4 (MIDI note, I believe)...
I'm in that horrible questioning state. No, not trying to figure out if I'm gay. I'm trying to decide between Django and Rails. From what I've read, Django probably fits my needs better, both from a "cultural" and goal point of view. The baked-in admin interface pretty much sells me alone. However, I have one critical concern: it look...
Is there and way to write code like this in a way that makes what it does clearer? a = (a.split(" ")[1..-1]).join(" ") That deletes the first word of a sentence but the code doesn't look expressive at all. ...

Or maybe even String::split, because you could consider #split to be in the namespace of String. I've even seen the method alone, when the class is assumed/implied (#split). I understand that this is the way me...

I come from more of a C# background yet am learning Ruby in my spare time. Given classes, it is possible to make their methods private, public (default) or protected. While I understand their usage, is it typical for Ruby code to make use of such modifiers, despite being a dynamic language, in which the user can easily override access? ...

I am not sure what causes this error but since I came across this issue in passenger and now in the console as well I am thinking maybe the mysql driver is the problem? Everything works as expected on osx/10.6. It just won't on Ubuntu 8.04 hardy. I nailed down the problem to either the "destroy" method or also when I call a method of a...
