Learning Ruby on Rails any good for Grails?
My company is in the process of starting down the Grails path. The reason for that is that the current developers are heavy on Java but felt the need for a MVC-style language for some future web development projects. Personally, I'm coming from the design/usability world, but as I take more "front-end" responsibilities I'm starting to fe...

How can I encode xml files to xfdl (base64-gzip)?

Why doesn't Ruby have a real StringBuffer or StringIO?
I recently read a nice post on using StringIO in Ruby. What the author doesn't mention, though, is that StringIO is just an "I." There's no "O." You can't do this, for example: s = StringIO.new s << 'foo' s << 'bar' s.to_s # => should be "foo\nbar" # => really is ''` Ruby really needs a StringBuffer just like the one Java has. Stri...

Ruby mixins and calling super methods
Ok, so I've been refactoring my code in my little Rails app in an effort to remove duplication, and in general make my life easier (as I like an easy life). Part of this refactoring, has been to move code that's common to two of my models to a module that I can include where I need it. So far, so good. Looks like it's going to work out...
Drawing Library for Ruby
I am trying to code a flowchart generator for a language using Ruby. I wanted to know if there were any libraries that I could use to draw various shapes for the various flowchart elements and write out text to those shapes.

Why Doesn't My Cron Job Work Properly?
I have a cron job on an Ubuntu Hardy VPS that only half works and I can't work out why. The job is a Ruby script that uses mysqldump to back up a MySQL database used by a Rails application, which is then gzipped and uploaded to a remote server using SFTP. The gzip file is created and copied successfully but it's always zero bytes. Yet i...
OpenID authentication in Ruby on Rails
I am a neophyte with Ruby on Rails but I've created a couple of small apps. Anyway, I'm really interested in OpenID and I would like to implement OpenID authentication and maybe some Sreg stuff in a Rails app. All of the research that I have done has come up with articles that are out of date or just don't work for me. Since I'm so new t...
How do I access the Ruby AST from C level code?
I understand that the Ruby 1.8 AST is traversed at runtime using a big switch statement, and many things like calling a method in a class or parent module involve the interpreter looking up and down the tree as it goes. Is there a straightforward way of accessing this AST in a Ruby C extension? Does it involve the Ruby extension API, or ...
Is Ruby On Rails ready for the Enterprise?
Is anyone out there using RoR for large scale, business critical enterprise applications?

Ruby error "Superclass mismatch for class Tempfile"
A while back I migrated a ruby webapp (using eRuby - note: Not Rails) to my new server and in the process it seems to have got broken. I get the error "/usr/lib/ruby/1.8/tempfile.rb:12: superclass mismatch for class Tempfile (TypeError)". I can't see what changed in the migration - all the code stayed exactly the same. I've tried stripp...
JRuby / Rack deployment
I know this is pretty exotic, but I want to deploy a Ruby web application (not Rails, but Rack based, so it plugs into most Ruby servers just fine) using JRuby. Google and friends give me a few success stories, but mostly rails related and if not, no details on the deployment are provided. The framework I'm using is Ramaze, if it matters...

I've been using Eclipse with RDT (not RadRails) a lot lately, and I'm quite happy with it, but I'm wondering if you guys know any decent alternatives. I know NetBeans also supports Ruby these days, but I'm not sure what it has to offer over Eclipse. Please, list any features you think are brilliant or useful when suggesting an IDE, make...
Ruby blocks/Java closures in C
I've been trying to understand how Ruby blocks work, and to do that I've been trying to implement them in C (^_^). One easy way to implement closures is to pass a void* to the enclosing stack to the closure/function but Ruby blocks also seem to handle returns and break statements from the scope that uses the block. loop do break i if...
