Just to clear the air, I am not some cruel factory master trying to silence working ladies. I am having a very annoying problem where when using Thoughtbot's factory girl in my specs, every time Factory.create(:foo) is used, the newly created ActiveRecord model instance is logged to the console. This makes looking at my console output ...

In my rails project, I have a query which finds the 10 most recent contests and orders by their associated poll dates: @contests = Contest.find( :all, :limit => "10", :include => :polls, :order => "polls.start_date DESC" ) Currently this shows each contest and then iterates through associated polls sorting the master list by poll s...
I'm just doing some University related Diffie Hellmann exercises and tried to use ruby for it. Sadly, ruby doesn't seem to be able to deal with large exponents: warning: in a**b, b may be too big NaN [...] Is there any way arround it? (e.g. a special math class or something along that line?) p.s. here is the code in question...
I was having a really odd problem in my cucumber tests that was causing scenarios that were passing individually, to fail when run with others in a feature. I deduced this was a MySQL related issue and sure enough, a co-worker came along and recommended I change my connection pool to a higher value in my database config. Lo' and behold, ...

I then created another file to run the script using the trivial example they give you in the readme located at http://daemons.rubyforge.org/ . I require both rubygems and daemons. Then I type 'rub...

I am trying to figure out how to add search to my rails application. I am brand new so go slow.

Hello, I'm a Notepad++ user. One of the features I like from that software is the fact that you can have a "console" in the UI (which is not an actual terminal), and that you can run some command line interpreters from there. FYI, to get the console running in Notepad++, you need to have the NppExec plugin installed, and then go to Men...

How can I make emacs suppress additional brackets when I type in the closing brackets myself? I now am manually deleting the auto-magically inserted bracket every time. Thanks in advance...

Ideally, every character would be stored as a row in the database, along with the position it was inserted and a timestamp. I am hoping that there is either a good Javascript library th...
