  • How do you deploy an application.yml based config to heroku

    In one of my applications, I have the following config files that are excluded from git: * config/mongoid.yml * config/application.yml * config/mailserver_setting.rb * config/omniauth_settings.rb For deploying to a regular server, I just add tasks to my capistrano deployment file to create sym-links to a shared directory. In this case I have to modify my application…

  • Winds around the world

    Goal: characterize the winds available around the world. First we need to construct our grid: The horizontal, latitude-longitude grid ranges from +70 to -70 deg in latitude and from 0 to 357.5E deg in longitude, producing a grid that has dimensions of 57 x 144 points. In matlab, this is: [cells/degree northern_latitude_limit western_longitude_limit] zerom( These…

    This one should be simple, but it is not. I just wanted to know what to put on an Air Force form 938 for “MODE OF TRAVEL”. This wasn’t easy. In the JFTR, https://www.defensetravel.dod.mil/Docs/Training/DTA_App_C.pdf Appendix K, Table K-3 associates each travel mode with its description, expense category, and single threshold.

  • Mongoid counter_cache with has_and_belongs_to_many

    If I have two Mongoid models joined by a has_and_belongs_to_many relationship, Users and Groups. I need to quickly and efficiently sort by the most popular groups which really should be done with a counter_cache. However, counter_caches are implemented in rails by setting a callback to update the counter cache every time a child model is…
