movement: In the computer mobile process by a large vibration will often make the machine internal devices loose, resulting in poor contact caused by computer crashes. So you should avoid shaking when you move your computer. 3. Dust OFF: Machine components if contaminated with too much dust particles, such as head, resulting in read and write errors, serious will cause computer crashes and even make components damaged, so to keep the air clean, if the computer dust too much to be cleared. 4.

process of computer movement by a large vibration will often make the machine internal devices loose, resulting in poor contact, causing computer crashes, so mobile computers should avoid violent vibration. Usually in the discovery of the crash can also check whether the board is loose, can be pulled out and plug again. 3, Dust Killer Excessive accumulation of dust in the machine can also cause a panic failure. For circuit boards, dust is tantamoun

PRINTLN (Test ()) /// Panic () Recover () The panic () function is used to throw exceptions, and the Recover () function is used to catch exceptions, and the prototypes of the

First of all, I'm sorry, because of the move, too many recent things to deal with, resulting in more slow article updates.In this article, we talk about exception handling in go.Go provides two built-in functions panic () and recover () for exception handling.Go, the overall principle of exception handling is: Multi-use errors package, less use of panic.For predictable errors, such as network connection failures, errors is generally used, and only cri

Computer Crash reason The crash is to make the operator rather annoying things. When the performance of the crash is "blue screen", unable to start the system, the screen "freeze" no response, the mouse, keyboard can not be entered, the software operation abnormal interruption. Although the cause of the crash is a lot, but same, the reason is never out of hardware and software two aspects. caused by hardware panic "Bad Heat" monitors, power supp

the habit of disabling rows, and never forget rows at any time. close (). even if the rows is automatically closed after the loop is completed, we define the rows. close () is also good for us, because we cannot guarantee whether the rows will be finished normally.Query a single record, We use db. QueryRow () var name string err = db.QueryRow("select name from user where id = ?", 222).Scan(name) If no result is returned, the system returns the err.Process null values We use a record with
