I am trying to use a Rake task to migrate some legacy data from MS Access to MySQL. I'm working on Windows XP, using Ruby 1.8.6. I have the encoding for Rails set as "utf8" in database.yml. Also, the default character set for MySQL is utf8. 99% of the data is coming in fine, but every now and then I'll get a column value that gives me...

Here's a simple Ruby script: puts `ls -laG` In OS X's ls, -G is for color. When run under bash, I get color output. When the above is run from a Ruby script, I don't see color or the ANSI escape sequences in the resulting output. From what I've read, my guess is it's because the script isn't running as a tty. Is there some way to ru...

It seems to me like Ruby has a lot of syntactic flexibility, and many things may be written in several ways. Are there any language features/syntactic sugar/coding conventions that you avoid as a Ruby programmer for clarity? I am asking about things that you choose not to use on purpose, not stuff you still have to learn. If your answ...
Sorry if this problem might be a little too specific. I'm a RoR newbie still. I'm currently modifying an RoR app based on the Insoshi framework on windows vista. It uses Free Image and the image_science gem along with attachment _fu for uploading images to the application and resizing it. Every part of the application seems to be up and...

I want to develop an application with simple Quiz-like games (think of a question , answer, a timer, high-scores/ranking, not much more) For that I want to use Rails and some javascript library that let me have some modern effects on the GUI (being a GUI the least you can ask is for an atractive interface) I first considered ExtJS but ...

I'm migrating some data from MS Access 2003 to MySQL 5.0 using Ruby 1.8.6 on Windows XP (writing a Rake task to do this). Turns out the Windows string data is encoded as windows-1252 and Rails and MySQL are both assuming utf-8 input so some of the characters, such as apostrophes, are getting mangled. They wind up as "a"s with an accent ...
