Using the python2.7, the runtime appears with the ' ASCII ' codec can ' t encode characters in position 0-8: Ordinal not in range (128) error, by searching for some articles to learn because PYT The default encoding used by the Hon System is ASCII encoding, but the characters in the operation of the code are not in the ASCII range, so the error is incorrect.Workaround:Add 3 lines of code before the code1 Import SYS 2 Reload (SYS) 3 sys.setdefaultencod

PHP uses OpenSSL for RSA encryption, if the plaintext to be encrypted is too long error, workaround: Encrypt the time 117 characters to encrypt once, and then all the cipher stitching into a cipher text, the decryption time needs 128 characters to decrypt, and then splicing into data.Encryption:/** * Encryption * @param $originalData * @return string|void * //*function Encrypt ($originalData) { if (Openssl_private_encrypt ($o

Some Linux (Chinese version) Installation manuals often show that the swap space cannot exceed 128 MB. Why is there such a saying? Before explaining the history of the number "M", I would like to give a question: there is no m limit at all! The current limit is 2 GB! Swap space is paging. The size of each page is the same as that of the Memory Page, facilitating data exchange between swap space and memory. In the earlier version of Linux, when impleme

-Vmargs-xms128m-xmx512m-XX: permsize = 64 m-XX: maxpermsize = 128 m There are several questions:1. What are the meanings of each parameter?2.

Why didn't eclipse execute the corresponding settings when writing the above parameters to the eclipse. ini file?Let's answer them one by one. 1. What are the meanings of each paramete

Recently, the algorithm is a function that involves converting RGB to YUV data. This common error occurs: Unsigned char * vline = (New unsigned char [width + 2]); // + 1;// Uline [-1] = uline [width] = 128; // 16-bit binary representation of-1: 1111 1111 1111 1111At this time, uline mem points to the address 0xffff.Delet [] vline; Result: If you drop the row with a value of 128, the correct result is correc

Syntaxerror:non-ascii character ' \xe6 ' in file This problem occurs because Chinese appears in the code, and the workaround is to add it at the top of the code: #coding: Utf-8Unicodeencodeerror: ' ASCII ' codec can ' t encode characters in position 0-7: Ordinal not in range (128) The problem is that when writing Chinese in the program, the solution The method for adding at the beginning:Import sysreload (SYS) sys.setdefaultencoding ("Utf-8") is OK.Py

Concept: The complement of a negative number is the absolute value of the original code bitwise negation, and then the entire number plus 1Steps:1. Determine that byte is 1 bytes, or 8 bits2. The largest should be 0111 1111, because the first bit is the sign bit, 0 indicates a positive number3. The smallest should be 1000 0000, in the same vein, indicating the smallest negative number (1111 1111 is the largest negative number-1)4.0111 1111 That's 1275.1000 0000 According to the bottom of the exp
