  • 5 Roadblocks To Enterprise Rails Acceptance

    I love Rails for its pragmatic design and agile culture: two qualities not usually associated with the large, enterprisey systems of Fortune 500 companies.

  • Why Linux Won't Rule The Desktop Any Time Soon (1 of 2)

    Before the hate mail roles in, let me say that I’m a huge advocate of open standards and general use of F/OSS. I love Linux and use it almost exclusively for all my server side applications. I’ve used Linux on desktop systems for many years, have developed with it, had jobs supporting it, built custom…

  • Fixing "wrong number of arguments" Error w/Rails 1.2.3 Upgrade

    If you’ve just upgraded your Rails gem from 1.2.2 to 1.2.3 and are getting the following error on database hits.. wrong number of arguments (1 for 0) /opt/local/lib/ruby/gems/1.8/gems/activerecord-1.15.2/lib/active_record/vendor/mysql.rb:566:in `initialize’ ..note that updating RAILS_GEM_VERSION in environment.rb appears to be required.
