DescribeFor resistors with resistance of R1 and R2, the parallel resistor resistance formula is calculated as follows:R = 1/(1/R1 + 1/r2)Input two resistor impedance size, floating point, separated by a space. The impedance after the output is in parallel, the result is 2-bit sample input after the decimal point is retained1 2Sample output0.67Hint that the calcul
possibleMake sure that some attributes can inherit the parent rather than overwrite the parent;A simple example:
test jb51
test jb51
In fact, I want jb51 to inherit the default attributes, because those attributes already exist.In addition, we should pay attention to a few of the issues that are not particularly important. The impacts are not as big as those above:6. the CSS path should not be too deep;For example:Program code

1. http extension
As shown in, the extensions are included in Nginx. Below I plan to copy these extensions, which are similar to God.
2. Filter
What this guy can do is big ~ We can mount our Filter to the Nginx Filter to Filter data streams. We will not explain the specific application here.
Nginx ("engine X") is a high-performance HTTP and reverse proxy server and an IMAP/POP3/SMTP proxy server. NginxIt was developed by the rambler.ru site, where Igor Sysoev is the second highest traffic in Russia. It has been running on this site for more than two and a half years.

Follow the above steps to install Nginx. Because we use the default configure, it will be installed in the/usr/local/nginx directory. The corresponding configuration file is/usr/local/nginx/conf/nginx. conf. Open the configuration file and see the structure as follows:

Preface?? Because the applet wants to use HTTPS, it cannot modify the configuration that is already wired. So the simplest way is to use nginx forwarding, use HTTPS on Nginx, and then forward to the internal server. Nginx due to its excellent performance. A 4-core 16GB of memory is fully capable of supporting the daily million PV level of access.Basic knowledge??
