Pies is a Python 2 and Python 3 compatibility layer with the philosophy that all code should be Python 3 code. Starting from this viewpoint means that when running on Python 3, Pies adds virtually no overhead. Instead of providing a bunch of custom methods (leading to Python code which looks out of place on any version), Pies aims to backport as many of the Python 3 API calls, imports, and objects to Python 2 as possible, relying on special syntax only when absolutely necessary.
Bitcoin is a peer-to-peer electronic cash system that is completely decentralized, without the need for a central server or trusted parties. Users hold the crypto keys to their own money and transact directly with each other, with the help of a P2P network to check for double-spending.
Thread Safe Template Library (TSTL) is a C++ library that provides thread-safe containers with high grade of locking. It includes classes for multimaps based on a B-tree and a hash table. It also includes classes for a queue, a priority queue, a pipe, an alloccache, a timercache, a limitcache without global locking, and a fast shared mutual exclusion locker (also known as "rwlock" or "wmrg"). It's useful for writing multi-threaded applications, network services, and operating system components with high requirements for interactivity level.
xplain2sql converts files from Xplain to SQL. It supports a very large subset of Xplain, and it can convert from Xplain to Microsoft SQL Server, DB/2, Inprise InterBase, PostgreSQL, Oracle, MySQL 5, SQLite 3 or ANSI-92 SQL. It can also generate an XML description of the generated SQL. This XML description can be used to create low-level middle-tier code. Example stylesheets for Eiffel/ECLI and Delphi/ADO are included. The C source code release should compile on any platform with an ANSI C compiler. There are binary releases for FreeBSD, Linux, Solaris x86, and Windows 2000.
CreEPS is a collection of C++ classes that provide an easy-to-use interface for generating vector plots from within code. The drawings are stored as Encapsulated Postscript (EPS) files. It features all basic drawing elements, user-configurable fill types, and printf-style text output. Extensive documentation with many examples is included.
