Via Lobsters [1] (but really, many, many, other sites linked to this), “Paul
Ford: What is Code? | Bloomberg [2]”
Wow.
I've been a fan of Paul Ford [3] for many years (I even had a link to his
site in the sidebar years ago [4] but removed it as he hasn't updated his
site in several years now) so it's always nice when I come across his work
elsewhere.
This is a really good article on programming. It's also a really long article
(38,000 words) on programming. And while it's ostensibly for the non-
programmer (it uses second-person view point (which I do no like, Sam-I-am)
to paint you as an executive in a company trying to fund some internal
software development) I'm not sure if the average non-programmer won't be
overwhelmed by the presentation, or be unable to follow along when it gets
technical in spots.
Do I recommend it?
It's not technical enough for a programmer (and some of the details, while in
spirit okay, are technically inaccurate) but I'm afraid it might be a bit too
technical (or overwhelming) for its intended audience.
But yeah, I would recommend it.
You have been warned.
