SIMD-accelerated libjpeg-compatible JPEG codec library
libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs. libjpeg-turbo implements both the traditional libjpeg API as well as the less powerful but more straightforward TurboJPEG API. libjpeg-turbo also features colorspace extensions that allow it to compress from/decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java interface.

A tiny library to add auto discovery capability into your applications
A tiny and simple 100% Java library (without any dependency) to easily enable your application to automatically discover the presence of other instances of itself running on the other computers connected to the same LAN network, without having to deal with protocols and network configurations. The protocol used by the library is peer-to-peer, so you don't need a central server. The API is simple, straightforward and there are examples and full documentation to learn it in minutes.
Management and simulation of Electric Vehicles activities
EVLib is a library for the management and the simulation of Electric Vehicle (EV) activities, at a charging station level, within a Smart Grid environment. EVLib provides a simple, yet efficient interface for the management of all major EV related activities such as the charging and dis-charging of batteries, as well as battery swapping. Moreover, a large number of parameters, such as the number of chargers, the waiting queues, and the available energy can be easily configured. On top of this, the library supports the simultaneous operation of many EV activities through the efficient use of threads.
Fast, low overhead, stream-based transmission protocol
BPP (Binary Transmission Protocol) is currently only available in Java. This protocol is useful for all kinds of environment requiring a flexible and performance-based network transmission protocol. This protocol is intended for stream-based transmissions, but since it is stream-based it can be piped to almost any source that uses a standard Java InputStream or OutputStream.
An open source Java library for interprocess communications.
