Maarch is a DMS infrastructure dedicated to the legal archiving of high volumes of static documents. Unlike most DMS tools, it's a toolbox approach that allows one to build highly integrated custom applications. As a proof of concept, Maarch comes with two business applications: Maarch LetterBox for mail management and Maarch PeopleBox for HR document management.
Python Tracer lets you see your Python program's execution as a tree of function invocations, each tree node exposing the real time and CPU time (user/sys) of that call. The project consists of two main components: a Python tracer that can run your Python programs (much like "cProfile" and friends), and a GTK+ based GUI that can show the trace results. It uses a tiny auxiliary library (graphfile) to allow append-only writing and reading static DAGs directly from a file without reading it whole into memory at any stage.
The LA library provides a C++ vector and matrix class with an interface to BLAS and LAPACK linear algebra libraries and a few additional features. Templates (including some simple template metaprogramming) are employed in order to achieve generic applicability of the algorithms. In particular, iterative methods suitable for sparse matrices can be applied to your custom matrix class, which does not need to provide any explicit storage of the matrix elements (only matrix times vector operation has to be implemented).
