Editing 1586: Keyboard Problems

[[Cueball]] and [[Megan]] are trying to solve a keyboard issue, but are puzzled and baffled by the symptoms.

In the comic, [[Cueball]] complains that some keys in his keyboard don't work. Generally speaking, this could be due either to a software problem (e.g. the keyboard driver not working properly, or some program ignoring keypresses) or to a hardware problem (the keyboard is physically damaged, e.g. because of dirt under the keys).

If the problem is in the software, booting from a different operating system (e.g. an external recovery disk) should solve it, as the computer would no longer be using the faulty software. However, if the problem is in the hardware, changing the keyboard should solve the problem as the new keyboard should be physically undamaged (i.e. would presumably have no dirt under the keys).

However, the problem stays there after booting from an external recovery disk (so it's not a software problem) and it has "followed Cueball since his last computer," (i.e. the problem persists after changing to a new laptop with a new keyboard, so it's not a hardware problem). Cueball is (reasonably) puzzled.

[[Megan]] seems to be used to Cueball's computer behaving strangely, and she doesn't even attempt to explain or solve the problem. The only explanation she needs for the problem is that "it's Cueball's computer." The characters in this comic are probably the same as in [[1084: Server Problem]], [[1316: Inexplicable]], and [[349: Success]].

The last panel is a reference to {{w|The Terminator}}, a 1984 movie often referenced in xkcd. In the movie, the artificial intelligence named Skynet initiates a nuclear war, destroying most of humanity, then sends killing machines to finish the rest. These include flying drones — Megan suggests that if such robots come to Cueball's vicinity, they will (physically) crash since computers around Cueball can't seem to ever work properly, and so hiding in Cueball's house she should be safe from the robots.

The title text refers to main plot of the movie and its sequel {{w|Terminator 2: Judgment Day}}. As Skynet's army is losing the battle against the human Resistance movement, it finds a way to send a humanoid robot {{w|Terminator_(character)|T-800}} back in time to kill the mother of the Resistance's leader. The Resistance in turn sends {{w|Kyle Reese}} back in time to protect her. In the sequel, the situation repeats with the more advanced {{w|T-1000}} being the killer and a reprogrammed T-800 being the protector of the child (the future leader). Along the way, they manage to destroy the research lab where Skynet hardware is to be born in the future. The title text suggests an alternative mission into the past, sending Cueball back in time and using his power to cause Skynet to terminally malfunction instead of destroying it physically (as Skynet was created later anyway, despite the destruction of the research lab).
