[?] What happens to the money when you derail? Beeminder gets it. We hope you'll view it as a fair fee for the service, that happens to be waived if you never go off track. If you'd rather the money go to charity we highly recommend RunOrElse.
If you feel more motivated knowing that a greater percentage of your money would go to charity you might try Stickk.com, if you would be more motivated with none of your money going to charity at all you should check out Beeminder.com
"Seventy-five percent of Dutch women now work part time, compared to 41 percent in other European Union countries and 23 percent in the United States"
"Twenty-three percent of Dutch men have reduced hours, compared to 10 percent across the European Union and in the United States; another nine percent work a full week in four days."
The master/develop model gives you a pointer to the latest release for free. The pointer is called master.
Without the 'extra' develop branch, you have to remember or lookup the name of the latest release if you want to make a hotfix, or keep an extra tag for it, in which case the two models are the same.
I saw you have experience with Haskell, have you seen Yi? http://yi-editor.blogspot.com/ It has an Emacs and Vim frontend, but is far from being finished.
Yes, it is. That's an extremely old version I wrote as a "let's see if I can do this" project. You can see the newer one by browsing the subversion repository, which unfortunately is broken until I commit the fix tonight.
I'm working on integrating it with Google docs so that you can work on your documents using a vi/emacs-like editor, which is extensible just like emacs except using javascript rather than elisp.
I hadn't seen yi, but it looks very similar to what I want to do, which is combine the best of vi and emacs into a new editor. I'm particularly interested in decent web-based editors, however; the implementation language is secondary.
