I don't think so, I figure the ants are smart enough to find the nest when they are only a few steps away from it. Also, see my above example on drummers playing whole songs without counting. Counting is typically human and gets in a way when you play music, you only count when you are beginning and learning to play. Who knows ? Counting might be a very primitive behavior after all. If more intelligent life forms exist, maybe they don't need to count (i.e. use numbers);-))) Think of it, maybe humans count because their brain isn't sophisticated enough to remember quantities otherwise.
I am over doing it quit a bit but then again who knows ?;-)))

What I was trying to say is that counting usually involves numbers. You could build a car engine (or do almost anything) without using numbers. Instead of knowing the clearance for a given part is say 11mm, you could just use a mark on blank ruler or other tool the find out the right clearance. I suspect something similar is going on with the ants.
Also, I am glad you specified that you were no drummer. Drummers can reproduce songs with thousands of hits on the drum pads over and over again without counting. Don't let the drummer counting "1-2-3" at the beginning of a song fool you. He could as well go "Pom, pom, pom" and it would work as well.

If the experience results are valid, there is still a difference between counting and remembering and reproducing a sequence of movements.
Ants might remember that they have to do "step step step step step step step step" to get back to their nest without actually counting. This would seem much more natural to me.
Here is an example applicable to humans: As a drummer, I can create and reproduce the same roll on the fly. But if you asked me how many times I hit the drum pad, only then I would have to count. I did not need to count in order to reproduce the roll nor did I know how many times I actually hit the drum pads.
This leads me to believe ants cannot count, why would they need to. Counting is good for humans in order to trade, so they have developed that capability. Same goes for female animals that could notice one of their puppy is missing. They don't have to "count" them, they only have to remember a picture of all the puppies and notice the picture they now see is different from the normal picture. There is many more examples you can think off where one can appear to count without actually doing so.
Yep, of course they are byte arrays ! What else could they be ??? Not cow arrays for sure...;-)
But they are a lot more convenient than strings when you need to perform operations (like, add, multiply, square, etc. ) on the numbers;-))
Also, nowadays, some languages use 2 bytes for each char in a string in order to support unicode and still perform quick operations on strings. You would then waste some memory when you store a lot of very large numbers.
Finally, BigIntegers in the link I sent are actually bit arrays with a size rounded to the nearest multiple of 8. You must know that computers are much faster performing operations on binary representation of a number than on a string representation of the same number !;-)

At first glance, it sounds to me that if a plain user can install packages on a system outside its home folder, he must be granted root privileges through a setuid program somewhere along the path or be granted sudo root permissions. So why not just remove the setuid bit on the culprit program or remove sudo privileges ?
Removing setuid bit on some programs is a normal step for me in hardening the security level on any system. It seems to me like a more straight forward and surer way to close potential holes. By changing configuration parameters, one needs to actually look at the source code of the programs in order to make sure that the potential holes are actually eliminated.
Demolition needs to attack the structure. Actually, I think this is a good thing for stopping flying debris so blasting demolition crews won't have to put their own layer of "wallpaper" around the building to stop flying debris, thus making the demolition easier and cheaper;-))

Nope, both system are the same you are not taking into account the following factors:
1) additional hard drives will cause your power supply to generate more heat and to consume more energy.
2) additional hard drives will cause your controller to generate more heat and to consume more energy.
3) additional hard drives will cause all fans on your sytem to rev faster and to consume more energy.
4) Additional hard drives will cause your cpu to work harder generate more heat and to consume more energy especially if you are using software raid. If using hardware raid, your raid card will consume more energy.
etc. etc.
All these components don't have a 100% efficiency and transforming power from the 110 AC outlet produce energy lost trough heat.
Do the test yourself by measuring the power drawn from the AC outlet, not the power drawn at the hard disk connector.

Look at Quicksort in Haskell :
qsort [] = []
qsort (x:xs) = qsort (filter (= x) xs)
This is what I mean, no loops, recursion. I used Prolog and ML to solve logic problems and it is pretty handy. Prolog is especially suited for solving logic problems ( "logic programming" ).

WinMe, Win 98, Win 95 and Win 1.X were not even OS, they were just a graphical interface to DOS.
Still, they aren't considering windows 2000 and above as "true multitasking OS".

multitasking OS vs "true multitasking OS" ?
