Difference between string and text in rails? -

-

I am creating a new web app using Rail, and wondering, string and text and when should each be used?

The difference depends on how the symbol is converted into related column type in the query language.

With MySQL: string is mapped to VARCHAR (255) - 

 : string | VARCHAR | : Border = & gt; 1 to 255 (default = 255): text | TINYTEXT, TEXT, MEDIUMTEXT, or LONGTEXT2. : Border = & gt; 1 to 4294967296 (default = 65536)

Reference:

Use each When should it be done?

As a general rule of thumb, use : string for short text input (username, email, password, title, etc.) and : Text, for more expected input such as details, comment content, etc.

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).
