Where are you intending to install it? The 1.9.1 stuff exist there for comparability reasons, see the FAQ on this page.

I don't think you can switch window managers without logging out of X first.

You can define what window manager runs first (as well as starting other apps) in your .xinitrc file

To the original poster: Rails is not compatible with ruby 1.9.1, you have to use 1.9.2 or 1.8.7.

Try installing libzlib-ruby from apt-get.

If that doesn't work, then install with rvm which is...

./configure --prefix=/YOUR/NEW/DIRECTORY

Might I also suggest that in the ruby community, using rvm is the preferred way of installing ruby.

Just to throw another entry in, here is a recursive solution in ruby. Beware, this is extremely, extremely slow. No optimization here :)

You are absolutely correct. I was copying and pasting from my other program and I appear to have missed the temporary variable part.

Here's a pretty clean fix without having to use a temporary...

Very impressive, works beautifully. I'll take it that this wins the speed test.

Thanks. I've never taken linear algebra before so I was going just based on geometry.

Here is the improved version. The case/when statement could be replaced with Object.send, but I figured that...

Here is my solution in ruby:


#!/usr/bin/env ruby

transformations = STDIN.gets('end')

STDIN.gets # call gets again since STDIN still has a newline in it.

coordinates = STDIN.gets

Thank you Reiger, that's exactly what I wanted.

I really doubt that that image is part of the wxPython library. I imagine that when they say the word 'stock' they are referring to a generic image for a stop icon, not something specific to...

What compiler are you using?

Uhh...I think you may be confused. xinerama is not a video editing app.
And I understand the difference between a display and monitor. I guess the correct term would be screen since that's what...

So I've got xinerama working just fine. I have a question. I understand that xinerama treats dual monitors as if they were one single monitor, but is there a way for it to tell which window is on...

GNOME is a window manager, not an OS. All it is just a GUI overlay to a terminal and what you're requesting just doesn't make sense.

The expert challenge should be next where it uses numbers that are outside the range of primitive types.
