What library do you recommend for computer vision in Ruby?
Thanks.
Since OpenCV is quite widely used I'd probably have a look at Ruby/OpenCV.
Edit: I just remembered an interesting blog post about OpenCV in Ruby from a couple of month ago, this should get you up to speed with the lib:

I am the main developer of the HornetsEye library. It runs under GNU/Linux and it provides image processing operations as well as extensive integration of I/O libraries.

Due to the various issues with getting hsSDL to work on Windows, I'm looking for another library that can handle keyboard input and drawing images to the screen. Does anyone know of any?
I've successfully used gloss on Windows in the past without issues. It's also very simple (which I like) and is my go-to recommendation for people who want to use Haskell for simple graphics/ basic games.
Edit: It looks like gloss is having issues building on the Hackage server and as a result isn't displaying documentation. Here is the documentation for version 1.8.1.2, which should be about the same.

Expect seems to be a very powerful automation tool: http://www.nist.gov/mel/msid/expect.cfm
Is there a Ruby equivalent to that tool?
There's the pty package in the standard library, but that only implements a subset of the functionality of the Tcl package. In particular, it appears to lack the ability to wait for many patterns at once, or to provide interaction at the same time. Maybe this won't matter for what you're doing with it; a great many expect programs never make use of its full power.

What is the best Twitter API Library for Ruby?
I want to do simple things like:
search for specifics keywords for a date range
start following people
tweet messages
How can I do these things with the library you recommend?
I've used both twitter and twitter4r and I slightly prefer twitter. The latest release (0.7) supports twitter lists.
Twitter maintains a list of recommended libraries; this gem works pretty well.

Can anyone recommend an open source Ruby library for adding XMP metadata to JPEG images?
MiniExiftool, which is just a wrapper around the Exiftool command-line app, is the only open-source one I know of.
There's a commercial library called Chilkat, but I do not have experience with it, being that it is commercial.
