When you're hacking, the excess symbols between viable passwords selected and used to your
advantage.  You'll need to find clusters of symbols bracketed by parentheses, such as
(%$*!^*&&), which can be highlighted as a whole.  Submitting this should result in
a removal of a bad password or fully replenish your attempts.  Remember: you can always
back out and restart to avoid lockout.  Happy hacking!

If you want to avoid breaking precious Bobby Pins when picking various locks in Fallout 3,
exercise patience. If you've failed opening the lock on the first two tries, chances are a
third try will break the Bobby Pin. If you back out of trying to pick the lock and then
immediately reattempt it, however, your Bobby Pin's strength will reestablish itself,
giving you several more tries. Repeat this technique to never break a Bobby Pin.

To try this, you'll need to have the Mister Sandman perk activated, which will mean you
have to be at least at level ten. You'll also need a sneak skill of at least 60. If that
fits your character, then travel to Andale. Andale is full of kids that can't be killed
(killing kids in Fallout 3 is an impossibility). During nighttime, when everyone in Andale
is sleeping, break into various houses and kill the kids while sleeping using the Mister
Sandman perk. They won't die, but you'll still be rewarded experience for having killed
them. You can then repeat the process over and over again for infinite experience points.
