IT vs. Management
A man in a hot air balloon realized he was lost. He reduced altitude and spotted a woman below.
He descended a bit more and shouted, "Excuse me, can you help me? I promised a friend I would meet him an hour ago, but I don't know where I am."
The woman below replied, "You're in a hot air balloon hovering approximately 30 feet above the ground. You're between 40 and 41 degrees north latitude and between 59 and 60 degrees west longitude."
"You must be in Information Technology," said the balloonist.
"I am," replied the woman, "How did you know?"
"Well," answered the balloonist, "everything you told me is technically correct, but I've no idea what to make of your information, and the fact is I'm still lost. Frankly, you've not been much help at all. If anything, you've delayed my trip."
The woman below responded, "You must be in Management."
"I am," Replied the balloonist, "but how did you know?"
"Well," said the woman, "you don't know where you are or where you're going. You have risen to where you are, due to a large quantity of hot air. You made a promise, which you've no idea how to keep, and you expect people beneath you to solve your problems. The fact is you are in exactly the same position you were in before we met, but now, somehow, it's my fault.

Weapons of Math Instruction and Al-Gebra Movement
A public school teacher was arrested today at John F.Kennedy International Airport as he attempted to board a flight while in possession of a ruler, a protractor, a set square, a slide rule and a calculator.
At a morning press conference, Attorney General Alberto Gonzales said he believes the man is a member of the notorious Al-gebra movement.
He did not identify the man , who has been charged by the FBI with carrying weapons of math instruction.
"Al-gebra is a problem for us," Gonzales said. "They desire solutions by means and extremes, and sometimes go off on tangents in a search of absolute value. They use secret code names like 'x' and 'y' and refer to themselves as 'unknowns', but we have determined they belong to a common denominator of the axis of medieval with coordinates in every country. As the Greek philanderer Isos Celes used to say, 'There are 3 sides to every triangle'."
When asked to comment on the arrest, President Bush said, "If God had wanted us to have better weapons of math instruction, He would have given us more fingers and toes."
White House aides told reporters they could not recall a more intelligent or profound statement by the President.

If programming languages were cars
This is an update to an old series of jokes about computer languages being like cars.
C is a racing car that goes incredibly fast but breaks down every fifty miles.
C++ is a souped-up racing car with dozens of extra features that only breaks down every 250 miles, but when it does, nobody can figure out what went wrong.
Java is a family station wagon. It's easy to drive, it's not too fast, and you can't hurt yourself.
C# is a competing model of family station wagons. Once you use this, you're never allowed to use the competitors' products again.
Ocaml is a very sexy European car. It's not quite as fast as C, but it never breaks down, so you end up going further in less time. However, because it's French, none of the controls are in the usual places.
Haskell is an incredibly elegantly-designed and beautiful car, which is rumored to be able to drive over extremely strange terrain. The one time you tried to drive it, it didn't actually drive along the road; instead, it made copies of itself and the road, with each successive copy of the road having the car a little further along. It's supposed to be possible to drive it in a more conventional way, but you don't know enough math to figure out how.
[Monadic version:]
Haskell is not really a car; it's an abstract machine in which you give a detailed description of what the process of driving would be like if you were to do it. You have to put the abstract machine inside another (concrete) machine in order to actually do any driving. You're not supposed to ask how the concrete machine works. There is also a way to take multiple abstract machines and make a single abstract machine, which you can then give to the concrete machine to make multiple trips one after another.
Lisp looks like a car, but with enough tweaking you can turn it into a pretty effective airplane or submarine.
Prolog is fully automatic: you tell it what your destination looks like, and it does all the driving for you. [Addendum from Paul Graham:] However, the effort required to specify most destinations is equivalent to the effort of driving there.
Perl is supposed to be a pretty cool car, but the driver's manual is incomprehensible. Also, even if you can figure out how to drive a perl car, you won't be able to drive anyone else's.
Python is a great beginner's car; you can drive it without a license. Unless you want to drive really fast or on really treacherous terrain, you may never need another car.
Smalltalk is a small car originally designed for people who were just learning to drive, but it was designed so well that even experienced drivers enjoy riding in it. It doesn't drive very fast, but you can take apart any part of it and change it to make it more like what you wanted it to be. One oddity is that you don't actually drive it; you send it a message asking it to go somewhere and it either does or tells you that it didn't understand what you were asking.
Ruby is a car that was formed when the Perl, Python and Smalltalk cars were involved in a three-way collision. A Japanese mechanic found the pieces and put together a car which many people think was better than the sum of the parts.
Erlang is a fleet of cars that all cooperate to get you where you want to go. It takes practice to be able to drive with one foot in each of several cars, but once you learn how you can drive over terrain that would be very hard to navigate any other way. In addition, because you're using so many cars, it doesn't matter if a few of them break down.
Fortran is a pretty primitive car; it'll go very quickly as long as you are only going along roads that are perfectly straight. It is believed that learning to drive a Fortran car makes it impossible to learn to drive any other model.
Cobol is reputed to be a car, but no self-respecting driver will ever admit having driven one.
Forth is a car you build yourself from a kit. Your car doesn't have to look or behave like anyone else's car. However, a Forth car will only go backwards.
Assembly Language is a bare engine; you have to build the car yourself and manually supply it with gas while it's running, but if you're careful it can go like a bat out of hell.
Eiffel is a car that includes a built-in driving instructor with a French accent. He will help you quickly identify and learn from your mistakes, but don't you dare argue with him or he'll insult you and throw you out of the car.

The Great Keyboard Escape
Run little guy, run!
Maybe he just needed a little 'Space' and a new 'Home' that he could 'Insert' himself into to 'Start' a new life before his 'End' came.
