Huida is a lightweight Web-based help desk system for cases where there might be only a single responder. It could also be used for consulting, social services, or similar. It supports PayPal as a means for purchasing access to the system, has threaded queries and responses, and generates static pages of user-published content.
Shasplit takes a large data block, splits it into smaller parts, and puts those parts into an SHA-based content-addressed store. Reassembling those parts is a trivial "cat" invocation. Repeating parts (e.g., from previous split operations) are stored only once, which allows efficient incremental backups of whole LVM snapshots via Rsync. Shasplit shows its strengths on encrypted block devices, but might be useful for non-encrypted data, too.
rgxg (ReGular eXpression Generator) is a C library and a command-line tool that generate (extended) regular expressions. It can be useful for generating expressions that match, for example, a specific number range (e.g. 0 to 31 or 00 to FF) or all addresses in a CIDR block (e.g. 192.168.0.0/24 or 2001:db8:aaaa::/64).
lihata is a compact textual language which can represent a tree of lists, hashes, and tables. The syntax tries to be minimal and flexible to allow formatting a lihata file to fit the context it represents. The source release contains an event and DoM parser and helper functions for maintaining lihata trees. lihata is a convenient language for both simple and complex configuration files and text representation of data files.
OnPosix is a tiny library to abstract POSIX mechanisms to C++ developers. Most features offered by this library can be found either inside the Boost library or in a library compliant with the C++11 standard. Unfortunately, however, for some embedded Linux devices, these libraries cannot represent viable solutions, due to the lack of memory space (for the Boost libraries) and the lack of a new C++ compiler (e.g., on Xilinx MicroBlaze). On these platforms, the OnPosix library represents a good and cheap solution to have object-oriented POSIX mechanisms. The library offers support for threads, mutual exclusion, sockets, logging, timing, etc.
The YB.ORM library aims to simplify writing C++ code that has to deal with SQL databases. The goal is to provide a convenient interface like SQLAlchemy (Python) or Hibernate (Java). The library itself is cross-platform and supports a variety of SQL dialects: SQLite3, MySQL, Postgres, Oracle, and Firebird. Integration with Boost, Qt4, and wxWidgets is built-in. In a typical usage scenario, you would describe your database schema and table relationships in a simple XML-based format, generate SQL code to populate database schema with tables, generate C++ classes, add application-specific logic to the classes, and use these classes in cooperation with the Session object to query objects from the database, create new or modify/delete existing objects, or link and unlink objects using relations. Simple serialization to XML is supported along with connection pooling.
uterus is a codec library for financial tick data with an emphasis on market data integrity and maintainability. It comes with a set of tools to convert (mux) and print (demux) data from some sources, and to perform standard tasks like selecting instruments, creating snapshots and candles from tick data, etc. Special care is taken to provide longevity and consistence. All timestamps are internally converted to coordinated time, and price and quantity quotes are converted to a monetary datatype which doesn't suffer from rounding errors. Most importantly, meta data is stored along with the payload data in an inseparable unit, to provide self-contained and self-documenting files or network streams.
