Here is what happened:
I got a message from the professor said that my report on the server (WindowsXP hoa) is missing.
How can a file be missing? It's all because of GUI designers' wicked evil plan to make us suffer.
I copy and pasted a previous report to fork it to be a current report.
cp ./prev.report ../new_project/curr.report
That's what I would do normally. But since Windows has GUI and stuff, I did:
right click prev.report -> click Copy -> open new_project folder -> right click -> click paste.
So I forked the previous report and finished the current report.
Then after the Christmas and Hanukkah and other holidays, I get a message from the prof saying that my previous report is missing...
So, I remotedesktopped to the server and right clicked a file in Explorer...oh oh oh

OH MY GOOOOOOOD MOSES' GREAT GRAND PARENTS' GREAT CAT!!!!!
The right click menu was like:
+---------+
|Copy |
|Cut |
+---------+
Why on earth do they put Copy and Cut close together??
People like me who don't play Half life 2 so our mouse skils suck will possibly click 1 pixel below Copy and initiate Cutting process, which envolves i don't know my cereal!!!!!

So, they should make it like this:
+---------+
|

Copy

|
|Cut |
+---------+
And when the mouse goes over Cut, it should change the background to red telling users it's a D A N G E R O U S operation. Or, they should send content of the cutted file or stuff to their Customer Report or something..you know the thing pops up when WindowsXP can't handle your hawtness...
So, I demand GUI designers to bear in mind that we dumb users need Audio/Visual input when we have slight chance of messing up our reports stored on Windows server!
