In the process of using AFNetworking2.0, there are times when the operation couldn ' t be completed. (Cocoa error:3840.)

For example, we have a VMware environment with a host of the runtime ESXi, with 10 SAS disks on it. The five discs in these 10 disks were RDM to a virtual machine. Suppose you find that you have added a piece of disk and you want to remove it, but 5 of the disks have 3 discs already in use (i.e. they have production data on them). However, in the VMware Virtual Machine Properties dialog box, you can only see hard disk X, physical LUN and Datastore Mapping file numbers do not seem to work, how to

This article was written one year ago and was not completed for some reason. Today, I sorted out shadowstar's home and accidentally found this unfinished article. Although it was a year ago, it is still not out of date and should be helpful to anyone who wants to know sniffer. My father said that everything should start and end. Today is the Dragon Boat Festival. I would like to send a message to my loved ones who are far away from each other.

languages, strings are treated as reference types, not primitive types, because the length of a string is variable. ECMAScript has broken this tradition.If a value is a reference type, its storage space is allocated from the heap. Because the size of the reference value changes, it cannot be placed in the stack, otherwise it will reduce the speed of the variable search. Instead, the value placed in the stack space of the variable is the address that the object stores in the heap. The size of th
data. This variable is only generated when it encounters data that does not recognize the MIME type. $HTTP _raw_post_data is not available for enctype= ' multipart/form-data ' form data. This means that using $http_raw_post_data cannot receive data from a Web Form POST.
Php://input Way to receive data
If the better way to access the original POST data is php://input. Php://input allows the raw data to be read from the POST. Compared to $HTTP _raw_pos
Today, a friend's laptop blue screen cannot be started, and her optical drive is also broken. If the optical drive is not broken, we can take a ghost disk directly for the following work (winpe must be included, which is more convenient, start winpe ). Now that the optical drive is broken, I will remove the hard drive directly. Now it's all SATA interfaces, and it's okay to directly mount it on the desktop. I tried a variety of methods, and finally I looked at all the other disks, that is, the o
1, Form-data:is the multipart/form-datain the HTTP request, which will process the form into a single message, labeled as a unit, separated by a delimiter. You can upload a key-value pair or upload a file. When the uploaded field is a file, there will be content-type to the table name file type; content-disposition, which is used to describe some information about the field;Because there is boundary isolation, so multipart/form-data can upload files, you can also upload key value pairs, it takes

About PHP MD5 16-bit raw binary output and 32-bit string output
Because PHP AES is required to encrypt data, consider using PHP MD5 to output 16-bit binary as the key.
Google a bit "php MD5 16"? I found a lot of articles that are suggested to be implemented by intercepting strings, and the statements are as follows:
?
Perhaps they need a random string of 16 bits in length, and more likely they understand the true meaning of MD5.

TypeAnother type with only one value is null, and it has only one private value, NULL, which is its literal. The value undefined is actually derived from the value null, so ECMAScript defines them as equal.Although the two values are equal, they have different meanings. Undefined is a value that is assigned to a variable when it is declared but not initialized, and null is used to represent an object that does not already exist (this is briefly described when discussing the typeof operator). If
Java defines eight basic types of data:,,,,,, byte short int long char float double and boolean .The base type is often referred to as a simple type.These basic types can be divided into four groups:
Integers-include:,,, byte short int and long , for integer signed numbers.
Floating-point number-includes float and double , represents a number with fractional precision.
Characters-include characters that represent symbols in the character set, such as letters and numbers.
