The core idea of the verification algorithm of data communication: In order to ensure the reliability of the communication data, it is usually added to verify whether a frame of data is wrong, there are many kinds of verification, the XOR check is a common one, you this like 2 floor said, is byte by bit XOR operation, the result is placed in the last byte, The receiver receives the data for the same calculation, and if the last byte is the same as the computed result, the frame data can be consi

Server|sqlserver for database deadlocks, it is usually possible to determine the origin of the deadlock problem through trace FLAG 1204, 1205, 1206, checking the output inside the errorlog, and analyzing the SQLTrace execution context. The third parameter of the Traceon function is set to-1, which means not only for the current connection, but for all, including future builds of connection. This is sufficient, otherwise it is just monitoring the datab

The importance of arrays in programming languages is self-evident, and in JavaScript, arrays are one of the most commonly used objects, arrays are ordered collections of values, and because of the weak type, the arrays in JavaScript are flexible and powerful, It's not like a Java. Strong-type advanced language arrays can hold only the same type or its subtype elements, JavaScript may hold multiple types of elements in the same array, and can be dynamically adjusted in length, which can be change

One, variable batch renaming: For example, to change the number of variables a_2 b_2 c_2 d_2 e_2 suffix to W ren (*_2) (*W) Second, check the duplicate data commonly used commands: Duplicates report X//Reports x variable has no duplicates Duplicates list x//list duplicate records Bys X:gen Cn=_n Browse if Cn>1 Drop CN//Browse specific duplicate values for next step analysis and processing Duplicates drop x//delete duplicate value, keep first record of duplicate value Third, the data transverse l

oracle| Data | database | Statement code: Select Sql_text, Sharable_mem from V$sql where Sharable_mem > ' 100000 ' Order by Sharable_mem; 　　 　　 The above SQL statement is a query for SQL statements that consume more than 100K of memory in a shared pool. 　　 This SQL can be very effective at checking out those heavily memory-intensive SQL in Oracle shared Pool, and, in my experience, most problematic SQL statements leave traces here, by locating t

Mysql Case sensitivity and checking rules When using mysql, you may encounter similar problems: Root @ chuck 07:42:00> select * from test where c1 like 'AB % ';+ ----- +| C1 |+ ----- +| Abc || ABD |+ ----- + Fuzzy match AB %. Strings starting with AB also appear in the result set, which is naturally considered to be case sensitive. In mysql, how is the big and lowercase sensitivity controlled? How are the dictionary objects such as database names, tab

Self-checking is one of the protection methods of many software. Adding a simple shell to the software and then adding self-checking can resist a majority of new users in a certain program. However, for many people, this protection is weak. However, there is no systematic article in the search forum. I don't know if everyone is too busy or because they want to keep some secret. In fact, most technologies sh

We know that JavaScript is a weak type of language, and that everything in JavaScript is essentially an object. So, how to do object type checking in JavaScript is a very important topic.Here, I will describe two methods that are commonly used in JS for type detection.The first approach is to use the "typeof" operator, which may be known to everyone. The result of using it for type detection is one of the following six strings: "Number", "Boolean", "O

There are three reasons for this problem (usually only two on the Internet ): First, I have never encountered such a bad track, so as long as I don't often attack hard disks, there will be no bad track. If it is true, I should follow the online method to say, block bad channels. Second, file inconsistency or errors, usually caused by abnormal shutdown. You can do this with a disk checking at startup without worry! Third: serious file errors. I do not
