In Linux, Nginx logs are regularly cut and logs generated several days ago are deleted. Nginx logs are classified into access logs. log and error. log, where access. log records users, pages, user browsers, ip addresses, and other access information. error. log records server error logs. The error. log format is as follows:201.158.69.116--[03/Jan/2013: 21: 17: 20-0600] fwf [-] tip [-] 127.0.0.1: 9000 0.007 MX pythontab.com GET/html/test.html HTTP/0.00

. Common baud rates include 9600 bps or 115200 BPS, and the lowest baud rate is 110 bps, the maximum value is 256000 BPS (currently tentative ). The so-called baud rate is how many bits of data can be sent by the serial port within one second. In addition, the baud rate is also the cycle of one bit of data, or the retention time of one bit of data. Take 115200 BPS as an example: 1/115200 = 8.68e-6 The one-bit data cycle of the 115200 baud rate is 8.68us. If we use a clock frequency of 50 MHz to

1. Use getwd () to get the current working directory, and setwd ("E:/rproject") to set the working directory. Note that it is a slash rather than a backslash. 2. Read. Table () Mydata = read. Table ("filepath/FILENAME"), read data from filename, and create an object named mydata in the Data box. Detailed Syntax of read. Table, use? Read. Table. 3. Scan to read files Scan is more flexible than read. Table. You can specify the type of the read variable, and scan can be used to create differe

four 6-bit bytes (3*8 = 4*6 = 24 ), then, add 6 bits to two more 0 bits to form four 8 bits. In another simple and effective way, we can convert each 8-bit byte into four 2-bit bytes, and then replace them with four characters. The encoding and character schemes are as follows: 00---g 01---f 10---w 11 --- Space In this way, the encoded string will only contain 'G', 'F', 'w', and spaces. For example, the ASCII code of the character y is 121, and the corresponding binary string is 01111001. After

An Access Denied error occurs after the LNMP environment is set up. After the LNMP environment is set up, an Access Denied error occurs. Now, the File Permission problem has been ruled out and Nginx problem has been ruled out, but PHP cannot be resolved. I found that many of the online bulls used Nginx logs to troubleshoot errors, but I opened nginx. conf and found that my log information was not detailed enough. So I hope to configure log_format.
