What are u-quarks and d-quarks?
It's different types of quarks.
As far as we know now there are six different quarks, but only two of them (u and d) build up matter.
U and d stands for "up" and "down", and is made to different them from each other.
A u-quark is charged with +2/3 and a d-quark with -1/3.
A Proton is made up of two u-quarks and one d-quark, which gives it the charge 2* 2/3 - 1/3 = 1
A neutron is made up of two d:s and one u, which gives it the charge 2/3 - 2* 1/3 = 0

A Programmer and an Engineer were sitting next to each other on an airplane. The Programmer leans over to the Engineer and asks if he wants to play a fun game.
The Engineer just wants to sleep so he politely declines, turns away and tries to sleep. The Programmer persists and explains that it's a real easy game. He
explains,"I ask a question and if you don't know the answer you pay me $5. Then you ask a question and if I don't know the answer I'll pay you $5." Again the
Engineer politely declines and tries to sleep.
The Programmer, now somewhat agitated, says, "O.K., if you don't know the answer you pay me $5 and if I don't know the answer I pay you $50!" Now, that got
the Engineer's attention, so he agrees to the game. The Programmer asks the first question, "What's the distance from the earth to the moon?" Then Engineer doesn't
say a word and just hands the Programmer $5.
Now, its the Engineer's turn. He asks the Programmer,"What goes up a hill with three legs and comes down on four?" The Programmer looks at him with a puzzled
look, takes out his laptop computer, looks through all his references and after about an hour wakes the Engineer and hands the Engineer $50. The Engineer politely
takes the $50 turns away and tries to return to sleep.
The Programmer, a little miffed, asks, "Well what's the answer to the question?" Without a word, the Engineer reaches into his wallet, hands $5 to the Programmer,
turns away and returns to sleep.
Here's another one!
An engineer dies and reports to the pearly gates. St. Peter checks his dossier and says, "Ah, you're an engineer -- you're in the wrong place."
So the engineer reports to the gates of hell and is let in. Pretty soon, the engineer gets dissatisfied with the level of comfort in hell, and starts designing and building
improvements. After a while, they've got air conditioning and flush toilets and escalators, and the engineer is a pretty popular guy.
One day God calls Satan up on the telephone and says with a sneer, "So, how's it going down there in hell?" Satan replies, "Hey, things are going great. We've got
air conditioning and flush toilets and escalators, and there's no telling what this engineer is going to come up with next."
God replies, "What??? You've got an engineer? That's a mistake -- he should never have gotten down there; send him up here." Satan says, "No way. I like having
an engineer on the staff, and I'm keeping him." God says, "Send him back up here or I'll sue."
Satan laughs uproariously and answers, "Yeah, right. And just where are YOU going to get a lawyer?"
An engineer says that equations approximate the reality.
A physics says that reality approximates equations.
A mathematican just can't see the connection.

There were four programmers on a cruise ship. An American, a Russian, a Cuban, and an Indian.
The Russian takes out a bottle of fine Vodka, takes one swig and throws it overboard.
The American programmer says, "Hey, do you know how much that costs?" The Russian replies, "In Russia it costs nothing."
Next, the Cuban pulls out a fine cigar. Takes one puff, and throws it overboard.
The American programmer says, "Hey, do you know how much that costs?" The Cuban replies, "In Cuba it costs nothing."
With that, the American programmer throws the Indian overboard....

Discussion between two computer professionals about a software...
Last year, my friend upgraded his GirlFriend 3.1 to GirlFriendPlus1.0 (marketing name: Fiancee1.0).
Recently he upgraded Fiancee1.0 to Wife1.0, and it's a memory hogger! It has taken all his space; and Wife1.0 must be running before he can do anything. Although he didn't ask for them, Wife1.0 came with Plug-Ins such as MotherInLaw and BrotherInLaw. These too slow down the system and cause a slow drain on the resources and well-being of the computer.
Some features I'd like to see in the upcoming GirlFriend4.0:
1. A "Don't remind me again" button.
2. Minimize button.
3. Shutdown feature - An install shield feature so that Girlfriend4.0 can be completely uninstalled if so desired (so you don't lose cache and other objects).
I tried running Girlfriend 2.0 with Girlfriend 1.0 still installed; they tried using the same I/O port and conflicted. Then I tried to uninstall Girlfriend 1.0, but it didn't have an uninstall program. I tried to uninstall it by hand, but it put files in my system directory.
Another thing that sucks--in all versions of Girlfriend that I've used is that it is totally "object orientated" and only supports hardware with gold plated contacts.
It also gives a 'Bug warning' as..
Wife 1.0 has an undocumented bug. If you try to install Mistress 1.1 before uninstalling Wife 1.0, Wife 1.0 will delete MSMoney files before doing the uninstall itself. Then Mistress 1.1 will refuse to install, claiming insufficient resources.
Oh, they have recently released a patch for that. Its called Gun 1.0. You use it on Wife 1.0 ONLY. Then Mistress 1.1 will run flawlessly, allowing you to use your system normally again.

Both of them ask the same question to each other.
So, Which Platform are you Working on ???...
If you uninstall Wife 1.0 does it cause your system to restart? And if you install Girlfriend 2.0 it installs a Trojan just in case Wife 1.0 get back on the system.

Haha, just seen this, that's great :DQuote:

Here's another one
A lawyer defending a man accused of burglary tried this creative defense:
"My client merely inserted his arm into the window and removed a few trifling articles. His arm is not himself, and I fail to see how you
can punish the whole individual for an offense committed by his limb."
"Well put," the judge replied. "Using your logic, I sentence the defendant's arm to one year's imprisonment. He can accompany it
or not, as he chooses."
The defendant smiled. And, with his lawyer's assistance, he detached his
artificial limb, laid it on the bench and walked out.
