I haven't had a blog for half a month. I am busy with my work. Thank you for your attention.There are two things to do today. The first is to announce the answer to the last "interesting mind-reading.The second is to paste two functions used in the work to calculate the number of bytes of the half-width/full-width string.

Don't be nervous, don't doubt, the landlord is not fooling around :) In fact, this is not the smallest! I hope you can continue to explore it.
This article does not have any tricks and is the most basic technology. Even the rookie knows that it is impossible to save a 0.1 billion pixel photo to several hundred bytes, not to mention lossless. In fact, it is indeed impossible, because the title of this article does not refer to pictures, but images with
When calculating the length of a string, the first function that most people have flashed in their minds is Len (), the number of characters returned by the function (numbers of characters), with no trailing spaces, but with leading spaces.example, the Len function returns the number of characters, not the number of bytes of characters.Declare @str_v varchar(Ten)Declare @str_nv nvarchar(Ten)Set @str_v='AB'Set @str_nv=N'AB'Select Len(@str_v) asLen_v,Le
How does php convert received bytes to Unicode encoding? in C #, I convert the Unicode encoding of Chinese characters into byte streams and then POST them to the site. However, after receiving these characters, php always displays question marks, how can I transfer received bytes to Unicode encoding ??? How does php transfer received bytes to Unicode encoding?

The answer is: yes. It is about 5-15 kb. I don't know what the default value is. I tested 16371 bytes. Win7 x64.
You can use setsockopt to set the recvbuf or sndbuf size. However, we recommend that you set the number of bytes received each time to a certain range, such as 5 kb. Because even if it is set, it is still possible to accept a small number of bytes.

Why is the member function pointer in C ++ 16 bytes?When we talk about pointers, we usually assume that they are something that can be expressed using the void * pointer. In x86_64, they are 8 bytes in size. For example, the following is an excerpt from an article on x86_64 in Wikipedia: Pushes and pops on the stack are always in 8-byte strides, and pointers are 8 bytes
JavaScript code that limits the number of text bytes in form /*

Usage instructions:
Add (1) onkeyup = "limitLength (this. value, 100, 'name', 'name ')"
(2) id = "name" or [struts tag] styleId = "name"
Note: the id and attribute names must be the same.

Recently I have read the above explanation in a book about code auditing. Here we can explain exactly how many bytes the int should take. From its perspective, the compiler adapts to the platform. Therefore, it depends on your device platforms to determine how many bytes the int occupies. In fact, both short and char models are consistent. The most common model we see is the ilp32ll model. In this model, in

Py3, String, str type, is Unicode encoded format. Other types are byte, encoding format is GBK,UTF-8, etc.Instead of checking the encoding format of the STR type, Chardet is checking the encoding format of byte type.A= "ABC Ah", is a string, you can not use Chardet.When the type of data (byte) is obtained, it needs to be treated as a string, which needs to be encoded into Unicode (this is what Python handles).To convert bytes to Unicode, you need to k

Error when running Telnetlib: Typeerror:a Bytes-like object is required and not ' str ' due to differences in Python2 and Python3 versions.It works in Python2, and the most important new feature of Python3 is the clearer distinction between text and binary data. Text is encoded in Unicode and is of type STR, while binary data is bytes type.Python has two types of conversion functions encode (), decode ().
