Sure, I'll try to elaborate. Suppose you're reading a biography of Huygens. You may find yourself inspired to memorize a few of the basic facts therein. Dutifully, you feed his life's dates, his major acquaintances and mayb

I wrote a program I fancifully called 'Human Unit Tests' to aid me in my studies (learning a diverse set of constants for biophysics). I can very much attest to the effectiveness of spaced repetition. But, /boy/, do you

The point isn't easily settled, it seems: I am having a hard time to find financial statements from Debian. Ubuntu, or rather Canonical, being a private company, doesn't seem to release financial information. The Ubuntu main page

Those are some rather interesting documents, thanks! In 2013 FSF paid $ 689,239 in salaries and, astoundingly!, $ 48,995 in credit card fees.

I freely confess to being flabbergasted by these displays of less-than-rigorous thought processes. How would a free software project 'pay it forward'? They are in a very similar position, aren't they? Edit: For some reason, I

Ah, but what is discipline? Shifting the vocabulary burden around doesn't accomplish much. Discipline easily translates to will power (to do even in the face of adverse circumstances). But haven't we learned recently to consider
