hamsterdb Embedded Storage is an embedded database engine for C/C++, including wrappers for Java, .NET, and Erlang. It supports in-memory databases, very fast database cursors, "record number" databases, ACID transactions, and duplicate keys. hamsterdb is very fast and highly configurable. It compiles and runs on Unix platforms, Linux, Microsoft Windows, and embedded platforms.
The 3Gdb Home Subscriber Server implements the HSS network element within an IP multimedia subsystem (IMS) core network (CN). An IMS CN is a collection of SIP proxies, registrars, and servers used for the provision of services in a 3GPP all-IP mobile network. The HSS provides a centralized data base for subscriber records and generates authentication vectors.
teeterl is a lean, portable implementation of Erlang. teeterl starts from a single executable file without any additional harness. teeterl is built using Apache Portable Runtime, a library tested on dozens of OSes and their flavors. teeterl borrows from industry-standard Erlang/OTP, especially when it comes to compiler front-end. teeterl provides the concurrency power of Erlang without any telecom cruft.
Jingle Nodes is a relay auto-discovery service that provides Jingle Relay Type Candidates that can be used in ICE-UDP and also on RAW-UDP Jingle sessions. Relay candidates can provide NAT traversal for users who don't have STUN/TURN Support, but also for users with STUN/TURN support for whom negotiation failed. It is designed to allow you to communicate freely with your friends without being attached to closed service providers like Skype or telecommunications carriers.
VoltDB is a blazingly fast relational database system. It is specifically designed to run on modern scale-out architectures: fast, inexpensive servers connected via high-speed data networks. It is aimed at a new generation of database applications - real-time feeds, sensor-driven data streams, micro-transactions, low-latency trading systems - requiring database throughput that can reach millions of operations per second. What’s more, the applications that use this data must scale on demand, provide flawless fault tolerance, and enable real-time visibility into the data that drives business value. It includes client application drivers for applications written in Java, C++, C#, PHP, and Python. VoltDB community members have also authored client libraries for Erlang, Ruby and Node.js. There are streaming export capabilities for leading analytic database environments, including Apache Hadoop.
epers stands for "Erlang persistence". As the name suggests, it tries to make it easy to use databases in Erlang programs, to make the language a little more agile, and (humbly) offer a nice adapter for several databases, hiding their implementation details (and the API of the library/framework/driver used to communicate with them). To achieve this, it aims to offer a somewhat consistent API to define and work with your model, while at the same not coupling your code too tightly to it.
Ybot is erlang bot software inspired by Github hubot. It supports IRC and XMPP transports and is extensible with plugins. Plugins can be written with Python, Ruby, or shell. It supports IRC chat, XMPP multi user chat, and 37 signals Campfire chat. It can simultaneously run any number of bots on different transports.
RabbitMQ is an implementation of AMQP, the emerging standard for high performance enterprise messaging. The RabbitMQ server is based on a proven platform, Erlang/OTP, offering exceptionally high reliability, availability, and scalability. It delivers good throughput and latency performance that is predictable and consistent. The code base is compact and easily maintainable, facilitating rapid customization and hot deployment. The RabbitMQ distribution also includes a Java client that interoperates with any compliant AMQP server.
