One thing I really miss about Java is the tool support. FindBugs, Checkstyle and PMD made for a holy trinity of code quality metrics and automatic bug checking. Is there anything that will check for simple bugs and / or style violations of Ruby code? Bonus points if I can adapt it for frameworks such as Rails so that Rails idioms ar...
As it stands now I'm a Java and C# developer, but the more and more I look at Ruby on Rails, the more I really want to learn it. What have you found to be the best route to learn RoR?

Hi! I'm starting to learn ruby. I'm also a day-to-day C++ dev. For C++ projects I usually go with following dir structure / -/bin <- built binaries -/build <- build time temporary object (eg. .obj, cmake intermediates) -/doc <- manuals and/or Doxygen docs -/src --/module-1 --/module-2 -- non module specific sources, like main.cp...

I'm not entirely sure if this is possible in Ruby, but hopefully there's an easy way to do this. I want to declare a variable and later find out the name of the variable. That is, for this simple snippet: foo = ["goo", "baz"] How can I get the name of the array (here, "foo") back? If it is indeed possible, does this work on any variab...
Anyone came across something like Dive Into Python for Ruby? Something that: Gets the language knowledge across by examples of real code that does something useful not just trivial one-liners Is ment for experienced programmers, not newbies (i.e. does not explain obvious stuff like object-orientation and what is a instance vs. class va...
I am using ActiveScaffold in a Ruby on Rails app, and have replaced the default "actions" text in the table (ie. "edit", "delete", "show") with icons using CSS. I have also added a couple of custom actions with action_link.add ("move" and "copy"). For clarity, I would like to have the icons displayed in a different order than they are. ...
I am using ActiveScaffold in a Ruby on Rails app, and to save space in the table I have replaced the default "actions" text in the table (ie. "edit", "delete", "show") with icons using CSS. I have also added a couple of custom actions with action_link.add ("move" and "copy"). For clarity, I would like to have a tooltip pop up with the r...

I am wanting to use ActiveScaffold to create assignment records for several students in a single step. The records will all contain identical data, with the exception of the student_id. I was able to override the default form and replace the dropdown box for selecting the student name with a multi-select box - which is what I want. Th...
I want to make a copy of an activerecord record, changing a single field in the process (in addition to the id). What is the simplest way to accomplish this? I realize I could create a new record, and then iterate over each of the fields copying the data field-by-field - but I figured there must be an easier way to do this... such as:...
I recently bought a Windows Mobile device and since I'm a developer I want to use it as a development platform. Yes, it's not supposed to be used like that but it's always with me and my laptop isn't. I know cke is a good editor for code but how can I run JavaScript/Ruby code without too much of a headache? I probably could write a web ...

From my experiences building non-trivial applications in Java and C#, I know that using good modular design based on known patterns and "coding to interfaces" are keys to success. What are the architecture best practices when building large systems in a dynamic language like python or ruby? ...
