Ransack is a rewrite of MetaSearch created by Ernie Miller and maintained by Ryan Bigg, Jon Atack and a great group of contributors. While it supports many of the same features as MetaSearch, its underlying implementation differs greatly from MetaSearch, and backwards compatibility is not a design goal. Ransack enables the creation of both simple and advanced search forms for your Ruby on Rails application (demo source code here). If you're looking for something that simplifies query generation at the model or controller layer, you're probably not looking for Ransack (or MetaSearch, for that matter). Try Squeel instead.

Sequel is a database toolkit for Ruby. * Sequel provides thread safety, connection pooling and a concise DSL for constructing database queries and table schemas. * Sequel also includes a lightweight but comprehensive ORM layer for mapping records to Ruby objects and handling associated records. * Sequel supports advanced database features such as prepared statements, bound variables, master/slave configurations, and database sharding. * Sequel makes it easy to deal with multiple records without having to break your teeth on SQL. * Sequel currently has adapters for ADO, DB2, DBI, Informix, JDBC, MySQL, ODBC, OpenBase, Oracle, PostgreSQL and SQLite3.

skalibs is a package centralizing the public-domain C development files used for building other skarnet.org software. skalibs can also be used as a sound basic start for C development. There are a lot of general-purpose libraries out there; but if your main goal is to produce small and secure C code, you will like skalibs. skalibs contains exclusively public-domain code. So you can redistribute it as you want, and it does not prevent you from distributing any of your executables.

STFL is a library which implements a curses-based widget set for text terminals. The STFL API can be used from C, SPL, Python, Perl and Ruby. Since the API is only 14 simple function calls big and there are already generic SWIG bindings it is very easy to port STFL to additional scripting languages. A special language (the Structured Terminal Forms Language) is used to describe STFL GUIs. The language is designed to be easy and fast to write so an application programmer does not need to spend ages fiddling around with the GUI and can concentrate on the more interesting programming tasks.

The Google Data APIs (GData) provide a simple protocol for reading and writing data on the web. Each of the following Google services provides a Google data API: * Base * Code Search * Blogger * Notebook * Calendar * Webmaster Tools API * Health * Google Analytics Data Export API * Picasa Web Albums * Google Book Search Data API * Spreadsheets * Google Finance Portfolio Data API * Documents List * Google Maps Data API * Contacts * Sites Data API * YouTube * Issue Tracker Data API * Google Apps Provisioning The GData Python Client Library provides a library and source code that make it easy to access data through Google Data APIs.

XParam is a general-purpose tool for parameter handling in C++. It allows object serialization and deserialization in a format that is human-readable and -writeable, and is unaffected by issues of word-size and endianity. The XParam format is also not confused by objects containing pointers: it saves the objects in such a manner that their conceptual contents can be restored perfectly. For this reason, XParam provides an excellent tool for cross-program and cross-platform communication. In future, XParam may also be extended to allow cross-language communication, but for now it is only available in C++.

ZooKeeper is a distributed, open-source coordination service for distributed applications. It exposes a simple set of primitives that distributed applications can build upon to implement higher level services for synchronization, configuration maintenance, and groups and naming. It is designed to be easy to program to, and uses a data model styled after the familiar directory tree structure of file systems. It runs in Java and has bindings for both Java and C. Coordination services are notoriously hard to get right. They are especially prone to errors such as race conditions and deadlock. The motivation behind ZooKeeper is to relieve distributed applications the responsibility of implementing coordination services from scratch.

gdnsd is an Authoritative-only DNS server. The initial g stands for Geographic, as gdnsd offers a plugin system for geographic (or other sorts of) balancing, redirection, and service-state-conscious failover. If you don't care about that feature, it's still quite good at being a very fast, lean, and resilient authoritative-only server for static DNS data. gdnsd is written in C using libev and pthreads with a focus on high performance, low latency service. It does not offer any form of caching or recursive service, and does not support DNSSEC.
