I wrote in a previous post about a web thingy so you could find out if it was OK to bike or not? Back then it was basically working, but since then I've added the ability to specify your own preferences, rather than being stuck with mine, or using a really long URL. Now it's got its own domain name and a logo.
So now you can bookmark http://okto.bike and check every day if it's OK to make your regular bike trip.
Next step with this - rewrite it in Ruby on Rails because that's what the cool kids are using.
