I've tried Sage twice but have found the documentation lacking both times. I ended up going back to the individual programs that make it up (Octave,R) and an easier computer algebraic system (mathomatic).

I never thought that history of some math software can be that interesting. Good read.

The "a" in the title is wrong; "software" is a mass noun, not a count noun.

... and the article has random line breaks which makes it almost impossible to read. :)

They're not random, they're at 75 characters! But granted, it does make it difficult to read. Transforming between soft line breaks and no line breaks is a trivial ignored computing problem in my opinion.

This -> http://lab.arc90.com/experiments/readability/ fixes it right up.

read PDF version instead

Or disable/zap CSS.

EDIT: One relatively non-invasive means:

I suggest that one not use bookmarklets without examining them first, confirming for oneself that the are safe. Fortunately, this one's very brief and apparent.
