A Brief, Incomplete, and Mostly Wrong History of Programming Languages:
1842 - Ada Lovelace writes the first program. She is hampered in her efforts by the minor inconvenience that she doesn't have any actual computers to run her code. Enterprise architects will later relearn her techniques in order to program in UML.
1987 - Larry Wall falls asleep and hits Larry Wall's forehead on the keyboard. Upon waking Larry Wall decides that the string of characters on Larry Wall's monitor isn't random but an example program in a programming language that God wants His prophet, Larry Wall, to design. Perl is born.
1995 - At a neighborhood Italian restaurant Rasmus Lerdorf realizes that his plate of spaghetti is an excellent model for understanding both the World Wide Web and that web applications should mimic their medium. On the back of his napkin he designs Programmable Hyperlinked Pasta (PHP). PHP documentation remains on that napkin to this day.

What purports to be an interview with an anonymous Facebook employee, shedding some light on the inner workings of Facebook, technical improvements, privacy, and the more unusual dealings with its millions of users:
How do you think we know who your best friends are? But that’s public knowledge; we’ve explicitly stated that we record that. If you look in your type-ahead search, and you press “A,” or just one letter, a list of your best friends shows up. It’s no longer organized alphabetically, but by the person you interact with most, your “best friends,” or at least those whom we have concluded you are best friends with.
I’m not sure when exactly it was deprecated, but we did have a master password at one point where you could type in any user’s user ID, and then the password. I’m not going to give you the exact password, but with upper and lower case, symbols, numbers, all of the above, it spelled out ‘Chuck Norris,’ more or less. It was pretty fantastic.
I found a fake account created from Berkeley that used the profile picture and information from the brother of one of my very good friends. We looked up the guy who created the original profile, and he had never ever heard of him, never ever met him, obviously had never seen him. But this guy had evidently added him as a friend, and sadly he accepted it, but literally stole all of this guy’s information, created a fake account, and was communicating with himself from the fake account. He was writing on his wall and posting back to the “other person’s” wall. We found out the guy actually had about fifteen fake accounts that he created, stealing other users’ pictures and information to create the accounts, and was actually communicating back and forth with himself. Just to try to make himself appear cool, I guess?The unnamed Facebook employee also says that they're working on something named Hyper-PHP, which will compile PHP (which Facebook is written in) to machine code, which, they claim, will reduce CPU usage by 80%.

A technical problem causes Facebook to display its PHP source code; someone grabs this source code and posts it online; the code itself doesn't contain anything more revealing than variable names and include paths. Meanwhile, the non-technical press posts vague yet ominous-sounding warnings about how it could help criminals to steal users' identities (conceding that it doesn't actually allow them to do so as such).
Which is not to say that there aren't any risks; as always, one should exercise common sense. Facebook is an entertainment site, and thus engineered to less stringent standards of security than, say, banking sites. Even if the site itself is secure, your "private", "friends-only" information could fall into the hands of third parties in other ways (if, for example, criminals take control of a router between you and the Facebook servers and sniff all the traffic going through it, or if one of your friends (who is able to see your information) has a Windows virus on their PC which captures the pages they see). The same goes for other sites with "friends-only" capabilities, such as LiveJournal, Flickr, or various members-only forums or mailing lists.
