The pyenv command manages multiple Python versions.
Since accessing Python, virtualenv and virtualenvwrapper have been used to manage the dependent environments of different projects. It is a pleasure to switch the virtual environment through commands such as workon and mkvirtualenv.
However, recently I want to make the project compatible with more Python versions. For example, if I want to be compatible wi

PHP under IIS, Microsoft has given the fastcgi solution. FastCGI can allow the PHP process to be reused instead of every new request to re-open a process. FastCGI can also allow several processes to execute simultaneously. This solves the problem that the CGI process pattern consumes too much, and the CGI process pattern does not have the advantage of the thread security problem.Therefore, if you are using ISAPI to run PHP, you must use the thread safe version, while running PHP in fastcgi mode
engine will iterate through the array until the target is found by implementing this method. So this function will waste a lot of time. The 2nd method uses a hash table. Deposit an object in the form that has already appeared through the subscript. The reference to the subscript is much faster than searching the array with indexof.To determine the efficiency of these three methods, I made a test program, generated an array of 10000-length random numbers, and then used several methods to test th

If you have more than one Java JDK version installed in your system, you may be able to switch back and forth depending on the project or the compilation environment, and there are two very handy ways to choose between them.I have Java 7 and Java 8 on my machine, and you are modifying it according to your own JDK version.Method One: in your home directory. Add the following to the Bash_profile file, or create one yourself if the file does not exist. Export JAVA_HOME_7=/LIBRARY/JAVA/JAVAVIRTUALMA
