ImageScalr Java image scaling library

imgscalr is an very simple and efficient (hardware accelerated) “best-practices” image-scaling library implemented in pure Java 2D; as of the 4.0 release imgscalr now includes a handful of other convenience image operations, all as easy to use as resize.
This library makes  uses of efficient Java2D scaling techniques advocated by the Java2D team which provides hardware accelerated operations on most platforms.

The Java Chronicle Library

The Java-Chronicle library attempts to provide ultra low latency, high throughput, persisted, messaging and event driven in memory database with random access to previous messages) The typical latency is as low as 16 nanoseconds (between processes), supporting throughputs of 5-20 million messages per second.

Technical Features

• It uses almost no heap with trivial GC impact regardless of size, 
• It can be much larger than your physical memory size (only limited by the size of your disk). and can be shared *between processes* with better than 1/10th latency of using Sockets over loop back. 
• You can attach any number of readers, including tools to see the exact state of the data externally. e.g. I use; od -t cx1 {file} to see the current state.
