I recently did a class assignment where I made a really hacky data structure. I ended up using nested hashes, which seems like a good idea, but is really hard to iterate through and manage. I was doing general stuff, like one tag maps to a hash of items that map to prices and stuff like that. But some of them were getting more complicat...
I've written two simple calculations with Ruby which match the way that Microsoft Excel calculates the upper and lower quartiles for a given set of data - which is not the same as the generally accepted method (surprise).

I have started encoding the input strings in the '\uXXXX' format, however I can not figure out how to convert this to an actual...

I am generating a CSV file from Ruby. The problem is a column string will contain double quotes, single quotes. How can I escape these things? "Mary had a little so called \"lamb\"","34","none" "something is not \"right\"","23","none" Each column is enclosed in double quotes followed by comma (and no space), and written into a file. ...
Hello! I am quite new to ruby but enjoying it so far quite immensely. There are some things that have given me some trouble and the following is no exception. What I am trying to do here is create a sort of 'super-directory' by sub-classing 'Dir'. I've added a method called 'subdirs' that is designed to list the directory object's fi...

I've written a feature for my library Rubikon that displays a throbber (a spinning as you may have seen in other console apps) as long as some other code is running. To test this feature I capture the output of the throbber in a StringIO and compare it with the expected value. As the throbber is only displayed as long as the other code...
