| Dynamic C++ Proposal|
Date: 18/12/2008 Author: Daniel Pistelli
A proposal of how to introduce dynamism into the C++ language. This proposal tries to cover every aspect, introducing, besides dynamic objects, also dynamic enumerators, namespaces and templates. The proposal also shows possible applications of the presented features. Although the paper is purely theoretical, it covers how dynamism can be implemented at low level. The reader of this paper ought to have a good knowledge of the C++ language. This article was released on codeproject.com and won the competition in the C++/MFC category for December, 2008.

| Rebel.NET Official Guide|
Date: 25/04/2008 Author: Daniel Pistelli
The official Rebel.NET guide. Rebel.NET is a rebuilding tool for .NET assemblies which is capable of adding and replacing methods and streams. It's possible to replace only a limited number of methods or every method contained in a .NET assembly. The simplicity of Rebel.NET consists in the replacing process: one can choose what to replace. Rebel.NET is, mainly, a very solid base to overcome every .NET protection and to re-create a fully decompilable .NET assembly. As such, Rebel.NET has to be considered a research project, not an encouragement to violate licensing terms.
