I can't find at least one good reason for this notation. Its a well
known
jokes that Hungarian notation was the reason that Win95 was delayed 2
years
because the programmer had to change every line of code :-)

In fact now you have this fucking WIN32 API where you can find lots of
places where the variable is different then the prefix. Event
datatypes change during program lifetime - ignoring this means simply
being a manager that has never written a really large software system.

If your variables are so short that you can't imagine the name you are
doing something wrong. I program in eiffel the whole day and we have
method names
like  "create_keyboard_shortcut_from_string". You read a program
multiple times
but you type it much less.
