This code works fine in C#: Expression.Lambda(LambdaBody); But none of the methods for building AST seem to visible from IronRuby. I required Microsoft.Scripting.Core and Microsoft.Scripting libraries. Do I need something else? Here is the IronRuby code: require 'C:\reorganize\software\ironruby-1.0rc3\ironruby\bin\microsoft.scripting...

The app uses subdomains as account names and will also eventually allow for a custom domain to be entered. I have an entry in production.rb to allow for cross-domain session handling. The problem is that you can...

I'm trying to do something with "neverblock" and I can't seem to get it to work. What I expect: The blocking sleep shouldn't slow down the whole process. I expected to see 5 times "bla" with basically the same timestamp. Ruby: $ ruby --version ruby 1.9.2dev (2010-03-31 trunk 27123) [x86_64-darwin10.2.0] Code: require "neverblock" fi...
Hi, While playing with RubyCocoa, I keep progressing with my idea for my application. Because my application will be going to use configuration files, I would like to know how I discover the relative path to store these inside my application structure (or if a better idea emerges, please elaborate also the "why").

I want to know how to open and manipulate a simple image file in Ruby language. I don't need to do any advanced stuff, just things like open(), get_pixel() and put_pixel() and I don't wanna use any gem for doing that, but just to know the barehands-ruby way. ...

I have a rails app that is a CMS that uses dynamic subdomains for each site. For some reason when I deployed to production the session cookie is not getting set. I'm thinking this is leading to the "Invalid Authenticity Token" errors that are being thrown everywhere. I have my production.rb setup so that I can share sessions across ...
I've got a few classes in lib/ which are not reloadable (due to their internal structure, its a jruby application). How can I tell rails to not reload these after each and every request? Thanks! ...

However I'd want to be sure that for every Foo, I have at least two Bar. I can't access the bar_attributes in my validations so it seems I can't validate it. Is there any clean wa...
What is the typical format/structure for creating an administrative area in a Rails application? Specifically I am stumped in the vicinity of these topics: How do you deal with situations where a model's resources are available to both the public and the Admin? i.e. A User model where anyone can create users, login, etc but only the ...
The Java debugger has a command called 'drop to frame' that takes you back to the beginning of the current method, resetting the stack as if you had just entered the method call. Static or instance variables won't be reset, but it's still pretty useful for when you stepped over a line and want to try it again. Is there the equivalent in ...
