ABOUT THIS DOC This doc will briefly introduce myself, my role in the company, what I value most and how to reach me. MY ROLE I’m a software developer that loves to see how a piece of code translates to a client satisfaction. I take pride on the small tools that make my life easier and on automating the tedious tasks. WHAT I VALUE Simplicity Simpler things describe the world better ...
Docker on FreeBSD is not an easy ride, several attempts failed to bring the popular container platform to this operating system. We have the outdated port, jetpack, and the popular Docker on Freebsd wiki article. But still, the process is not easy, and prone to failures. Jails is the popular choice to isolate applications in FreeBSD, it’s been a part of the operating system since FreeBSD 4.X, so it’s very robust and has a long story already. That could explain the lack of demand for supporting docker on a native or close-to native way. ...
This is the third part of the Protecting a Python codebase series. This time we will be playing with Python interpreter in order to protect the original code of a Python based project. The Python Interpreter Going to the basics, the Python Interpreter is a machine that: Consumes Python code (.py files, from the command line, from a REPL shell) Compiles the code to bytecode Executes the bytecode (here and here) Of course that’s a very rough description. But that’s enough to get started on modifying it to make your own version that will run your own code, and your code won’t run on others interpreters (even the standard one). ...
This is the second part of the Protecting a Python codebase series. This time we will be playing with Python Abstract Syntax Trees in order to protect the original code of a Python based project. Python Abstract Syntax Trees As the Python Documentation says: The ast module helps Python applications to process trees of the Python abstract syntax grammar. The abstract syntax itself might change with each Python release; this module helps to find out programmatically what the current grammar looks like. ...
The very nature of Python makes the task of protecting the source code complicated. As an interpreted language, the source code must be available in some form in order to execute it. During this article, I’ll write down the steps I’ve followed while trying to find a fit solution to the problem of protecting a Python based codebase. The explored techniques are implemented in the companion repository with a few more attempts that will be discussed in a second article. The objective in that project was to protect a simple Flask application with NumPy as a dependency. ...
