What I wanted to do was create a generator to track Twitter API calls (this is just for debugging, I know about rate_li...

I have a Ruby application (not using Rails) that use my own Ruby gems. I have these gems hosted on a local gem repository server. Some of these gems have dependencies on other publicly available gems from gemcutter (ex: haml, curb). Would it make sense to vendor/mirror these publicly available gems on my local gem server so that I would...
I would like to take out a parameter from url by it's name without knowing if it is the first, middle or last parameter and reassemble url again. I guess it is not that hard to write something on my own using CGI or URI, but I imagine such functionality exists already. Any suggestions? in: http://example.com/path?param1=one&param2=...

In Ruby, I need to time out the execution of a block of code after n milli seconds. I know that the Ruby Timeout library supports timeouts in seconds: http://ruby-doc.org/stdlib/libdoc/timeout/rdoc/index.html Is this possible? ...
As far as I know both rails:freeze:gems and rake gems:unpack are placing the gems to /vendor. rails:freeze:gems places them to /vendor/rails, gems:unpack place them to /vendor/gems. The point for me seems to be the same, however. In both cases the goal is to fix the gems and their versions as they were during the development. Is there an...

Hi, I wrote a small program that uses Mechanize to traverse a site. I want to write tests for it, but don't want it to actually go log onto the site every time I run the tests. I would like to mock the internet, so that when it goes to some site, it simply returns the stored results. Here is a small example, pretend my code's purpose ...
