Data transferred over such protocols must be represented as a subset of ASCII text (specifically, characters 33 to 126). read more

I interviewed Ewa Jodlowska, Executive Director of the PSF, to talk about the experience and see what we all can learn, and how we can be supportive of the non-profit that supports one of my favorite programming languages.

Software development is messy. So many wrong turns, typos to fix, quick hacks and kludges to correct later, off-by-one errors you find late in the process. With version control, you have a pristine record of every wrong turn and correction made during the process of creating the "perfect" final product—a patch ready to submit upstream. Like the outtakes from movies, they are a little embarrassing and sometimes amusing.
