Nat.exe is a program called "New Ghost virus" that can be used to achieve the illegal purpose of a virus, for example: 1, the operation can control some of the advertising program to achieve traffic profit; that is, the pop-up ad window that the user mentions 2, control the computer to become broiler, DDoS competitors or more sinister purposes. Phantom virus: Ghost Virus After a successful run, in the process, the system boot add-ins c

Dirty Read, Phantom Read, and non-repeatable READ + transaction ISOLATION level 1. Dirty read: Dirty read refers to when a transaction is accessing the data, and the data has been modified, and this modification has not been committed to the database, then another transaction also accesses the data, and then used this data.e.g.The original salary of 1.Mary was 1000, and the finance staff changed Mary's salary to 8000 (but not the transaction)2.Mary

, the query to the data is different. In general, you will only do it once, selectQuery, and use this time query data as the basis for subsequent computations. Because it is allowed to appear, it cannot be read repeatedly. Then any, the queried data may be updated by other transactions, and the results of the query will be indeterminate. Note: If allowed, do not read repeatedly, your query results will be indeterminate. An uncertain outcome, can you tolerate it. 3,

I. Database transaction ISOLATION LEVEL There are 4 isolation levels for database transactions, from low to high to read uncommitted, Read committed, Repeatable read, and Serializable, which can solve the problems of dirty reading, non-repeatable reading, and Phantom reading one by one. √: May appear x: does not appear Dirty Read Non-REPEATABLE READ Phantom reading Rea

The database has four isolation levels, namely:Solation_read_uncommitted: Allows reading of changed uncommitted data, which can result in dirty reads, non-repeatable reads, and Phantom reads.Isolation_read COMMITTED: Allows concurrent transactions to be read after committing, avoiding dirty reads, which can result in repeated reads and Phantom reads.Isolation_repeatable_read: Consistent with multiple reads

Label:Article Source: http://www.bkjia.com/sjkjc/806530.html The database's dirty reads, non-repeatable reads, and Phantom reads are all related to the isolation of the transaction. So first look at the 4 major features of the transaction.4 Characteristics of the transaction (ACID): Atomicity (atomicity): A transaction is a logical unit of work for a database, and its modifications to the database are either all executed or not executed at al

Chess pieces can be moved horizontally or vertically, moving over an adjacent piece, falling into the next free grid in the same direction, and removing the pieces that have been crossed. Now, we want to know if it's possible to pass several operations, leaving

Very early to do a "Lingbo micro-step" phantom effect, but there are many problems, such as: location is not accurate, need to set a lot of parameters beforehand, the camera's viewport clipping and position can not be updated dynamically, and the corresponding particle effects and other preset all with the main character matching good, today put these problems are modified, No matter where the character is in the screen, it can be very ideal to render

Foreign designers called "Ghost button" (Ghost Buttons), praised this kind of button permeability simple, fitting the overall style without losing charm, not attractive. The design of the bu
