  • BitTorious Trials

    New in BitTorious v4! BitTorious v4 has been released, and has received a comprehensive internal upgrade to Rails 5 and PostgreSQL 9.5. Also, all official releases from v4 forward will be built as portable Docker containers and distributed via Docker Hub. Due to attempted abuses of the evaluation environment, we’ve unfortunately had to discontinue the…

  • Capistrano Hanging During .tgz Upload

    I just spent an annoying amount of time troubleshooting a new cap-based deploy.rb for a Rails app to a new CentOS 6.4 server. The deploy.rb worked perfectly on other systems, but something about the configuration was causing `cap deploy’ to hang during the following: servers: [“myapp.example.com”] ** sftp upload /var/folders/0j/vmvt2by53m901wtmfv8xfjw40000gn/T/20130530225953.tar.gz -> /tmp/20130530225953.tar.gz Long story short,…

  • Proxy Authentication Against Devise-Based Ruby Applications

    (Quick GitHub link!) My team at TGen has a Rails application using a typical devise + cancan installation for authentication and authorization, respectively, and a related Apache HTTPD proxy server we needed to authenticate against active accounts in the webapp before passing traffic to their destination, which is a single host. We tried mod_authn_dbd for a…

  • Introducing RailRoady: The Rails 3 UML Diagram Generator

    I just released the first production version of the RailRoady gem about 5 minutes ago. If you’re a developer on Rail 3, you’ll definitely want to check it out. No more Vizio class diagrams! (RubyFlow announcement.)

  • Upgrading From Ruby 1.9.1 to Ruby 1.9.2

    I’ve spent half the day so far inbeded in the furious stressful upgrade process of a handful of Ubuntu Linux 10.04 and Mac OS X Snow Leopard systems from Ruby 1.9.1 to Ruby 1.9.2. I haven’t even gotten to the Rails 3.0.0 stuff yet: just the baseline Ruby installation. I’ve gone through the upgrade process…

  • The Truth About Integrating Rails In The Enterprise

    Ruby on Rails is a great RAD framework. We use it all the time. But one place Rails loses its magic–while not the fault of the framework itself–is with external integrations to legacy systems. First of all, soap4r sucks. Everyone I’ve seen try to pick it up has gotten frustrated and angry at how awkward…

  • Asset Tracking Webapp Written In Ruby On Rails

      Keeping track of company assets is important for insurance, warrantee and general informational purposes for purchased software licenses and hardware. I wanted a dirt-simple webapp written in Ruby on Rails, so I wrote one the other night and put the code on github. It’s a really simple Rails 2.2.2 app … no frills but does…

    I’ll be giving two sessions this Saturday, September 20th, 2008 at ABLEconf: Arizona Business and Liberty Experience hosted at the University of Advancing Technology. The first will be a ~50 minute getting-started-with-ruby-on-rails type session aimed at developers similar to the one I’m giving this Wednesday for Joe Developer. The second will be a plug-heavy talk over how…
