The leftmost column is a project that all administrators can configure. Let's look at it a piece. System Settings This part should pay attention to the two parts of e-mail and SSH. The mail server needs to be configured because the version control tool we use is git, so we need to upload here the private key created for review Board user. (Note that this is not the public key that needs to be uploaded, it is the private key.) ） Manage Th

reason is that after the page is loaded, there are only 40 pictures. If you need to get all the pictures, you need to manually swipe down the wheel before the page loads, and then the browser continues to send AJAX requests to the server for additional images. The method is practical and can get all the pictures.But! Manual operation This method is too low! Here is my guess: 1, can directly through the analysis of the source code in the JS section, directly extracted all the back to the server

thread-safe. groupby groupingSuppose you want to observe the number of bugs that the program appears in, grouping them into categories:Bugs. GroupBy (bug = Bug . AssignedTo) new {Developer = list. Key, Count = list. Count ()}) = = X.count);The result is a igroupingWhen you study enumerable classes, you tend to feel confused about what happened--for example, an overloaded version of GroupBy has 4 type parameters and 5 "normal" parameters (

non-recursive DFS and BFS, the difference is that a list is required to flag which nodes have been accessed to avoid loops. //2.

captured instead of its value when the delegate instance is created. The lifetime of the captured variable is extended, at least as long as the delegate that captures it. Multiple delegates can capture the same variable ... ...... But inside the loop, the same variable declaration actually refers to a different "instance" of the variable. The variables created in the declaration of the For Loop are valid only during the duration of the loop-not instantiated at each iteration of

. If the Fgets function succeeds, the return value is the address of the first element of the STR array, and NULL is returned if there is an error at the beginning of the end of the file or read data.int puts (char* str, file* FP);Outputs the string pointed to by STR to the file that the FP points to. The string at the end of the ' + ' does not output. If the output succeeds, the function value is 0, and if it fails, the function value is EOF. Read and write a set of data to a file in a

Forcing type conversions Basic data types Reference data type In Java, because of inheritance and upward transformation, subclasses can be converted very naturally to a parent class, but the parent class is converted to a subclass that requires casting. Because subclasses have more properties than the parent class and are more powerful, the parent class is forced to convert to subclasses. So, is it a success if the parent class is converted to a subclass? In fact, the forced ty

JAVA review 3 Java classes and objects I wrote two decommissioned articles, so I wrote something useful on my blog. If you want to learn JAVA, you must understand the relationship between classes and objects ,, because a major feature of JAVA is object-oriented .. Let's take a look at the concepts of classes and objects: (these concepts are annoying in school) Object: An object is an instance of a class

It belongs to the leak check.Java source files are compiled to generate a class file/bytecode file to help you achieve a truly cross-platform. A class is compiled into a class file. The execution is then interpreted through the JVM (the Java Virtual machine).Java of 8 a basic data type :Four integer types: Byte (1 bytes different and range different 2^7~2^7), short (2), int (4), Long (8)Two floating-point types: Float (4), double (8)Boolean type: Boolean (1)Character type: char (2)Java Specifica

choose to recover the directory. Dd command usageDd can also back up the file systemDd If = files_to_backup of = filename to back up files. Then, use dd If = filename of = files_to_backup to restore the file.The most powerful feature of the DD command is that the DD command can back up files directly at the block level. You can back up information such as MBR of a disk. For exampleDd If =/dev/sda1 of =/dev/sdb1 sdb1 is an unformatted partition, but after backup, sdb1 can be directly mounted
