django - online game best-practice -

-

I am developing a Django-based MMO, and I wonder what is the best way for server-client communication Will happen . I found the solution:

  • Periodic AJAX call
  • To keep a connection alive and send data through it

After Edit in:

This will include "You have a message", "User attacked X", "Transport has arrived for your X" and so on The numbers can increase (such as 1 / sec), but for a specific user they should not go up to 1 minute

  • The server does not respond immediately

  • Request
  • Before time, there is a state update in the server, and the server eventually responds to the customer, which can then update.
  • If there is nothing new to tell in fact, the update period The client within, then the server responds with the "no news" message before it expires, and the client "rests" "The request starts the request.

    • Benefit:

    • The customer does not have to do Ajax
    • Probably too much silly voting traffic is not.

    Disadvantages:

    • The server needs to have a more active connection open, and serve them for at least once time periods. In addition,
    • Depending on how well the server code supports multi-threading (does PHP help out there?), This code for code to handle AJAX responses and Can be more difficult.

    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).
