psopt-SourceCode
PSOpt is a program to demonstrate the optimization process of particle
swarm optimization. A two-dimensional objective function is visualized
by levels of grey: the lighter the color, the higher the function value.
The particles are shown as red circles, their trajectory as red lines.
The global memory (best point found up to now by the whole swarm) is shown
as a blue cross-hair, the local memory (best points found by each of the
particles) as small blue crosses. To run the program, first choose one of
the example functions, then create a particle swarm, and finally start the
optimization.

Apress-Pro-Android-Apps-Performance-Optimization-
I thank the team at Apress who made this book possible: Steve Anglin, Corbin Collins, Jim
Markham, and Jill Steinberg. Working with all of them was a real pleasure and I can with
confidence recommend them to any author.
I also want to thank the tech reviewers: Charles Cruz, Shane Kirk, and Eric Neff. They
provided invaluable feedback, often catching mistakes I would not have seen even after dozens of
readings.
To all my friends whom I did not get to see as often as I would have liked while I was working
on this book, I give my thanks too: Marcely, Mathieu, Marilen, Maurice, Katie, Maggie, Jean-René,
Ruby, Greg, Aline, Amy, and Gilles, I promise I will make up for the lost time. Last but not least, I
owe a lot to three people: Eddy Derick, Fabrice Bernard, and Jean-Louis Gassée. Sometimes all it
takes is an injured toe and a broken suitcase.

Akka集群
基于akka的集群例子，实用性很强，非常适合于分布式应用开发。可以自动发现新加入节点，自动负载均衡，自动消去down下去的节点。
