MySQL connection limit and PHP MySQL connections -

-

I'm having a frustrating problem In my web service, there is an email for php module in brief, once my user Sends an email to my dedicated email address, then my mail server captures email, pipe into PHP script running on my server This PHP script opens a MySQL connection and saves e-mail content to the database.

So far it is so good once the MySQL connection limit exceeds /etc/my.cnf, then the problem starts up is set to 500. If 500 or more users send email at the same time, my MySQL is unable to manage the new connection.

What do you suggest? Should I use a continuous MySQL connection or any other method like writing the received email content in a txt file and then save it to DB with a cron job?

Thank you for your suggestions!

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
