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.
phpVirtualBox is an AJAX implementation of the VirtualBox user interface written in PHP. As a modern Web interface, it allows you to access and control remote VirtualBox instances. Much of its verbage and some of its code is based on the (inactive) vboxweb project. It was created for people who prefer not to have to log in to their headless VirtualBox host to administer their virtual machines.
Genit is a framework that builds a static Web site, which does not require a server side programming language or database. Generated sites consist only of XHTML code (plus CSS and media). It runs from the command line, is based on XML, and is designed to be simple, readable, and minimalist.
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.
pyReScene is a tool that recreates original RARs by backing up the metadata. It is a port of ReScene .NET to Python. It provides a mechanism for backing up and restoring the metadata from "scene" released RAR files. RAR archive volumes are rebuilt using the stored metadata in the SRR file and the files extracted from the RAR archive. pyReScene consists of multiple related tools: pyReScene Auto to create a complete SRR with one simple command, pyReSample to recreate sample files, and pyReScene Usenet to create SRR files on the fly from Usenet postings. Lots of other small scripts for managing SRR and SRS files are available too.
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.
