Which is not to say you can't make money out of it
A common theme nowadays in the open source developers' circles is that you can't live writing open source. There are sad accounts of people abandoning their (popular) open source libraries, frameworks or programs, because they suck too much of author's time and with little or no financial gain. Others try their luck at Kickstart . . .
In context of software development
Software must have a purpose.
This is both self-evident and controversial. If we're expending serious effort to build it, it better have a purpose, but on the other hand, the purpose (the why) and the behaviour (the what) are often conflated.

This wasn't the case of me just not grooming the feeds. I heavily curated . . .
Ways of calling a piece of code incorrectly
Consider this Python function:
def factorial(n): """Returns n! (n factorial)""" result = 1 for i in range(2, n + 1): result *= i return result
Provided that this code is correct, what are kinds of errors (bugs) that can happen when this function is used?

What Shellshock can teach us about emergent behaviour
Let's backtrack a bit: how is it possible that a bug in command-line shell is exploitable remotely? And why is it a problem if a . . .
One person's account of a Kafkaesque process of purchasing a home
This is an old article from my Croatian blog. It would lose much in the translation, so it is reposted as-is.
