Mathcha

Mathcha is a horribly-named, arithmetic-based, text-driven captcha. Why you ask? For very few good reasons:

• I had never written a plugin.

• I wanted to play with a few bits of technology I hadn’t touched: git, github, gemcutter, gem packaging, jeweler, etc.

• I really like Recaptcha it’s just that I’ve seen a few folk using simple math problems and it’s

• I need this functionality across a few applications I’ve been working on.

This thing is nascent, fledgling, and was produced in a matter of hours. I haven’t thoroughly tested it yet so don’t put too much faith in it. Please feel free to fork and dress up. I plan on staying on top of this over the next few weeks and getting something put together that I’m happy to push on my peers.

Example

• In your view: <%= mathcha_tag %>

• In your controller: if (verify_mathcha(params))

• More soon.
