DBIX :: class hook provided It looks like you are starting with just the Pearl ORM - you should switch well. 

  @DSN = ('dbi: Oracle: ...', '...', '...', {autocompt => 1, on_connect_do = & gt; Qq [ALTER SESSION SET NLS_DATE_FORMAT = 'YYYY-MM-DD HH24: MI: SS'], QQ [ALTER SESSION SET NLS_TIMESTAMP_FORMAT = 'YYYY-MM-DD HH24: MI: SS'], QC [Altter session set NLS_TIMESTAMP_TZ_FORMAT = ' YYYY-MM-DD HH24: MI: SS TZHTZM '],],})

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).
