I have a quad display set up. It is working perfectly under FC22, but bombs on FC23. I wish I had more information for you, but I had to get this machine back up and running. Not only does the quad head not work, the one working head was operating at 1280x1024 versus 1920x1080. I tried doing a fresh install of FC23 and an upgrade from FC22 to FC23. It did not work in either situation. So, I

Hi! I''m *very* new to rails, I just dove in about a month ago and I''m loving it. One thing I decided I immediately wanted to do, was shorten the number of keystrokes neccessary to URI, HTML, or Jscript encode something. The project I''ve come into already has helpers defined for this. Right now, what I''ve done is: alias h! string_esacpe_html alias u!

I''m having a problem converting a date retrieved from my MySQL database and I''m hoping someone can help. MySQL stores the date/time as this: 2005-03-08 17:00:34.0 and according to my Pickaxe book Ruby stores times as "the number of seconds and microseconds since [...] January 1, 1970". All well and good. Unfortunately, RoR is converting my date to this:

I ran rdebug on it and it is trying to call I ActiveRecord::Base.connection.begin_db_transaction. from ActiveRecordSafetyListener.scenario_started. I don''t think SQLLite likes transactions.

MasterView is a rails-optimized (x)html friendly template engine plugin that provides another option to the existing rails view templates (rhtml and rxml).
