-I've nothing exciting to write about so I'll share a prank I did a few
-years ago (because I'm kinda proud of this one).
-
-To protect the innocent, I'll change all the names.
-
-I was working at a company named $LF. One of my colleague ($NG), always
-looks at his keyboard when he types. Some time he can type for a few
-minutes. Then he looks at his screen, only to realize that it's full of
-typo, or worse, that he had typed in the wrong window. This used to
-really bother me, because I know he's been typing for years, but I was
-not sure if he was looking at his keyboard because he needs to, or just
-because his head is too heavy to look at the screen.
-
-So one day, while everybody (except $GM) were away taking a break, I
-decided to conduct an experiment.
-
-The french keyboard uses the
-[[http://en.wikipedia.org/wiki/Azerty][AZERTY]] layout. $NG uses the
-[[http://www.gnu.org/software/emacs/][best editor in the world]], where
-the /x/ key is /really/ important (try to do something without
-'Meta-x'). He also uses a laptop, connected to an external monitor and
-with an external keyboard. So I decided to swap the /x/ and the /w/
-letter on the external keyboard, by switching the caps. The actual /x/
-and /w/ were still at the same place, only the label on the key was
-switched.
-
-When he came back from the break, he starts typing as usual. Quickly he
-realized that something was wrong, and he did a lot of things to figure
-out what. Among them:
-
-- verify that the content of =xmodmaprc= was correct, and then tweak it
-- reinitialize the layout with =setxkbmap=
-- use a tool (maybe =showkey= ?) to see what was the actual code send
- from the keyboard while hitting the key
-- probably recompiled a bunch of stuff
-- definitely upgraded his Linux distribution
-
-At this point, he understood that when hitting /x/, /w/ was received,
-and for /w/, /x/. He rebooted his laptop (because when in doubt, you
-should "[[http://www.youtube.com/watch?v=nn2FB1P_Mn8][tried turning it
-off and on again]]"). But the problem was still there.
-
-If I remember correctly, that's when he decided to look at the laptop's
-keyboard and tried to use it, only to realize that it was working
-correctly! So he asked the ops guy, $GM, who was sitting next to me, if
-there was a spare keyboard somewhere. I slowly turned my head toward
-$GM, whispering 'noooo' to him, and he replied to $NG "nop, sorry, no
-spare keyboard, ".
-
-The other developers started to realize that something was wrong with
-$NG, but no one said or did anything yet. We were about 30 minutes in
-the experiment now.
-
-Because he still had work to do, he tried to cop with the problem, and
-every time he needed a /x/ or a /w/, he would type something, stop, look
-at the screen, sigh/grumble, and use the laptop's keyboard to fix all
-the /w/ and /x/. That was difficult to miss, and soon other people asked
-him what was wrong, and so that's when I revealed .
-
-When I explained what I did he was surprised, starred at the two
-keyboards for a while, and saw that, effectively, the keys were swapped!
-I'm pretty sure the rest of the team made fun of him but I don't really
-remember exactly how.
-
-I consider the experiment to be a success: I proved that he need to look
-at his keyboard to type, and I'm also confident that I can reproduce it
-with the same subject multiple time and obtain the same result again.
