database - 'Followers' and efficiency -

-

I am preparing an app that will include users 'following' each other's activity, in twitter sense, but I am not much experienced with database / query design / efficiency, what are the best practices for managing this, etc. to avoid losses? Can I make a huge load on DB if I did not do it properly (or even?).

If it makes a difference, then it is possible that people can only be 'relatively' people (but one person can have many followers), although this is not definite, and I do not trust him Would like to

Thank you received gratitude by any advice.

Easy and easy to complete. If you have a user's table, with each unique ID, you have a TABLE_FOLLOWERS table with the column, USERID and FOLLOWERID For each user, describe all followers as one from one to many relationships.

Even with hundreds of assurances on half-decent database servers, it will display good and fast as long as you are using a good database (IE, MS-Access not).

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).
