A friend of mine asked to create a static website and I found that making such site using Sinatra is a pure joy. I just wrote all my routes like this: get '/index.html' do haml :index end get '/app.css' do sass :app end .... So I was able to use layouts, and haml and sass to put site together quickly. To create the static site ...
I've spent most of my time in statically typed languages (primarily C#). I have some bad experiences with the Active Record pattern and unit testing, because of the static methods and the mix of entities and data access code. Since the Ruby community probably is the most test driven of the communities out there, and the Rails ActiveReco...

Hi all, I am trying to write some code in ruby (using jruby) to be compiled to java bytecode with jrubyc and deployed to a remote machine where it will be run on the JVM (no ruby available there). Everything works fine as long as I am happy to stick with the standard jruby library. As explained on the jruby website, I simply copy the jr...
I just discovered MacRuby / HotCocoa and really like the sound of what they're doing. I had essentially discounted the prospect of making Cocoa GUI applications myself because I have an aversion to spending time & effort learning yet another C-based language, Objective-C. I'm not saying it's bad, just not for me. Is it the case now, or...

I would like to add :prompt to the select_tag :condition and select_tag :category fields and am having trouble. <ul id="homepage_searchbar"> <% form_tag junklists_path, :method => :get do...

The user-submitted information isn't visible to users until the administrator checks a check box and submits the form. So basically my problem is that if I check the check box as an administrator while initially creating an entry (entries#new) the entr...
G'day guys, I'm using fasterCSV and a rake script to parse a csv with about 30 columns into my rails db for a 'Trade' item. The script works fine when all of the values are set to strings, but when I change it to a decimal, int or other value, everything goes to hell. Wondering if fasterCSV has built in int etc parsing or whether I'll ...
I'm interested in creating a system where the user can define the steps in a workflow. Is there a gem that already handles this? I thought about one of the state machine gems, but they all seem to be for pre-defined states. I've been thinking maybe i can use state machine for the individual step types... An email step could have a few st...

I'm currently importing a CSV into an activerecord element but can't choose to parse the elements as say ints or decimals on a case by case basis using fastercsv. I can either choose to parse everything as an int or the other, or all as strings. I need to parse some columns as ints, some as decimals and some as strings. Otherwise, is th...

What is a good approach to sorting an array of strings in accordance with the current locale? For example the standard Array#sort puts "Ä" after "Z", which is not correct in German. I would have expected the gem I18n to offer a hook for defining my own sorting algorithms or providing collation strings or objects. In my imagination, pas...

I'm then given a time value in the form of %hh:%mm:%ss.%ms (the ms of which I can take or leave) and a third value of a GMT offset. I can't...
