io-util is a small, scalable Java library for slicing and dicing fixed width tables on disk. The objective is to provide reusable blocks of code for building efficient, custom binary data stores. It allows you to build, search, and maintain a large, externally stored, fixed width, sorted table. The library user specifies the row width (in bytes), a row comparison function (which implicitly defines any given row's key), and an optional delete codec.
WapSNMP is an SNMP client library for Go. It allows you to query SNMP servers for any variable, given its OID (no MIB resolution). It has been written to be in the Go style, which means it should be very resistant to all error conditions. It's entirely non-blocking/asynchronous, very fast, and will timeout, not block. It's also surprisingly small and easy to understand. It supports SNMPv2c or lower (not 3, due to its complexity), and supports all methods provided as part of that standard. This library works with OIDs and does not support OID-to-name translation.
The Eventual PlayFramework-AngularJS-Bootstrap-MongoDB Seed Project is a seed project that provides a CRUD implementation. It uses the Play Framework and MongoDB on the backend, and AngularJS and Bootstrap on the front-end. It is designed to underpin the development of future applications that adopt the same combination of technologies.
Messenger++ is a multi-protocol instant messaging client for Android. It features multi-protocol support (currently: XMPP, Facebook(XMPP), Google Talk(XMPP), VK, SMS) + audio calls if supported by the protocol. The UI is optimized for tablets. It is a Maven-based project with Robolectric tests built by Travis CI.
Vibur DBCP is a concurrent, fast, and fully-featured JDBC connection pool based on Java dynamic proxies. It supports a fairness parameter, statement caching, Hibernate integration, and SQL queries logging, among other features. Various configuration examples (with Spring, Hibernate, etc.) are provided.
