What is DNF's bug and how to use it?

The so-called "(Bug)" refers to an error in the hardware, system software (such as operating system) or application software (such as word processing software) of a computer system. There are two reasons for hardware errors, one is design error, and the other is aging failure of hardware components.

Software errors are all factory design errors. The suggestion that the user has carried out illegal operation is nonsense, and the software manufacturer is not responsible for it. The user may perform an incorrect operation, such as addition, but press the subtraction key. In this way, the user will get an incorrect result, but will not cause a bug attack.

A basic requirement of software manufacturers when designing products is that users are not allowed to do illegal operations. It is legal as long as users are allowed to do it. There is no way for users to know what the manufacturer thinks and which operation sequences are illegal. There have been computer bugs since the birth of computers. The first recorded error was discovered by GraceHopper, a programmer and inventor of the compiler in the United States Navy. Harper later became a general in the US Navy and led the development of the famous computer language Cobol.

65438+September 9, 0945, 3 pm. Captain Harper is leading her team to build a computer called Mark II. This is not a complete electronic computer, it uses many relays, a kind of electromechanical equipment. World War II is not over yet. Harper's team worked day and night. The computer room is an old building built during the First World War. It was a hot summer, there was no air conditioning in the room, and all the windows were open to cool down.

Suddenly, Mark II collapsed. Technicians tried many methods and finally found that the 70th relay was wrong. Harper observed the faulty relay and found a moth lying in the middle, which had been killed by the relay. She carefully took out the moth with tweezers and pasted it on the "event book" with transparent tape, and marked "the first case of insect discovery".

Since then, people have called computer errors debugging, and the work of finding errors is called debugging.

A hidden functional defect or error in a program. Because the complexity of software is beyond the control of ordinary people, mature operating systems such as Win95 and Win98 will publish bugs from time to time. How to reduce or even eliminate bugs in programs has always been a topic that programmers attach great importance to.

Super cruel picture. Look at the moth on the right

[Edit this paragraph] Game BUG explanation

Some online games may also have loopholes, which are called "bugs" by everyone. These loopholes can lead to the player's profit, the company's loss, or the state and effect disappear. In order to reduce this situation, game operators make game patches (not necessarily online games, but also stand-alone games have upgrade patches) (online games can be automatically updated, and stand-alone games must be downloaded again, especially windows games). Many players use these loopholes to make profits and highlight their own personality. Operators have the right to give titles to players.

For example:

BUG, the original curator of Karazan copy of World of Warcraft.

WOW players become level 60 account bugs in 10 minutes.

Legend of the Sword and the Chivalrous Man 4 Infinite Coin Bug

For example, punishing a knight is a bug.

There is a bug crossing the line of fire.

Aofa brainless biubiu is also a bug!

Dignity thief boneless is also a BUG!

QQ Three Kingdoms unlimited brush soul is also a BUG.

The suppression of warlocks by thieves is the biggest BUG in history!

If the BUG is very serious, the online game operation company will take back the file to reduce the loss caused by the player using the BUG or the BUG.

18-year-old Jessica Florence is the owner of this online best-selling mouse "Bug". /kloc-when she was 0/3 years old, she decided to feed a little mouse as a pet, but her idea was opposed by her parents at first. They tried to persuade her with words, but failed to shake Jessica's mind. Jessica is very fond of this little mouse, saying that Bug is educated and smart.
