The J! Scorer is a web app that makes it easy for prospective Jeopardy! contestants to keep score along with the show, and track their training progress via a bunch of different stats.

It is up and running on the web at Instructions for users can be found there, via the Help link.

See a sample stats page (and laugh at my actual stats!) here.

Developer info

The J! Scorer uses the following custom environment variables:

Variable Description
SUPPORT_ADDRESS The contact email address to display within the app.
SAMPLE_USER (optional) The id of the user whose stats should appear on the sample stats page. (User.first's stats are used if this is absent.)
SAMPLE_USER_NAME (optional) A string to display on the sample stats page instead of the sample user account's email.
PROPER_DOMAIN (production only, optional) (e.g., If a request gets to the app from any other domain (or subdomain), redirect it to this one.
MAILER_DOMAIN (production only) (e.g., The value of ActionMailer::Base.smtp_settings[:domain]. (From the docs: "If you need to specify a HELO domain, you can do it here.")
MAILER_HOST (production only) (e.g., The value of config.action_mailer.default_url_options[:host]. This is the base url for generated links in emails.


A plea: If there's anyone out there with an eye for design who's willing and able to help make the app look less ugly, without sacrificing usability, please get in touch. I will love you forever.

Check out the J! Scorer Main Project to see what I'm working on and what I'm planning to get to soon. Send me an email at the address below if you'd like to beat me to something on that list. If you want to do something else entirely, fantastic!

If you're an experienced open-source contributor

You know the drill. Fork, branch, pull request, ???, profit!

If you're new to this sort of thing

  • Check out GitHub's documentation for a good overview of the process.
  • Get in touch with me at the address below. I love helping others do nifty stuff with code almost as much as I love doing it myself.
