Practical Load Balancing

Book Description

The emergence of the and modern, fast corporate networks demands that you perform judicious balancing of computational loads. Practical presents an entire analytical framework to increase not just of one machine, but of your entire infrastructure.

Practical starts by introducing key concepts and the tools you’ll need to tackle your load-balancing issues. You’ll travel through the IP layers and learn how they can create increased network traffic for you. You’ll see how to account for persistence and state, and how you can judge the of scheduling algorithms.

You’ll then learn how to avoid performance degradation and any risk of the sudden disappearance of a service on a server. If you’re concerned with running your load balancer for an entire network, you’ll find out how to set up your network topography, and condense each topographical variety into recipes that will serve you in different situations. You’ll also learn about individual servers, and load balancers that can perform cookie insertion or improve your throughput.

You’ll also explore load balancing in the modern context of the . While load balancers need to be configured for high availability once the conditions on the network have been created, modern load balancing has found its way into the , where good balancing is vital for the very functioning of the , and where is becoming ever more important.

You can read Practical Load Balancing from end to end or out of sequence, and indeed, if there are individual topics that interest you, you can pick up this book and work through it once you have read the first three chapters.

What you'll learn

  • Judge network load balancing algorithms and when to use them
  • Plan your network for optimal load balancing performance
  • Configure single servers to take advantage of modern load balancing software
  • Learning to use load balancing software like HAproxy, STunnel etc.
  • Become familiar with implications of and the cloud
  • Improve throughput and seamless application cookie insertion

GIMP for Absolute Beginners

Book Description

for Absolute Beginners gives us an easy way to use the power of , and enjoy and graphics without worrying about application features.

GIMP is a powerful graphics and imaging application with almost all the features of its proprietary counterpart, Photoshop. But many of us are photographers and artists first, and we like to use our tools without having to think about them too much. GIMP for Absolute Beginners gets us to this stage without patronising users who haven’t used GIMP before.

But what can we actually do with photos and graphical images? These questions are answered in a photo projects chapter as well as a chapter on digital painting: Starting with making small changes to photos and adding information to them to creating paintings and drawings without photographic input.

What you'll learn

  • Learn how to install GIMP and navigate its interface
  • Improve image quality with GIMP
  • Increase your design prowess
  • Have fun with digital painting projects

Who this book is for
Hobbyists, occasional designers, enthusiastic photographers, graphical design amateurs, and beginning illustrators.

Hacking the Kinect

Book Description

Hacking the is the technogeek's guide to developing software and creating projects involving the groundbreaking volumetric sensor known as the . 's release of the Kinect in the fall of 2010 startled the technology world by providing a low-cost sensor that can detect and track body movement in three-dimensional space. The Kinect set new records for the fastest-selling gadget of all time. It has been adopted worldwide by hobbyists, robotics enthusiasts, artists, and even some entrepreneurs hoping to build around the technology.

Hacking the Kinect introduces you to for the Kinect. You'll learn to set up a software environment, stream data from the Kinect, and write code to interpret that data. The progression of hands-on projects in the book leads you even deeper into an understanding of how the device functions and how you can apply it to create fun and educational projects. Who knows? You might even come up with a idea.

  • Provides an excellent source of fun and educational projects for a tech-savvy parent to pursue with a son or daughter
  • Leads you progressively from making your very first connection to the Kinect through mastery of its full feature set
  • Shows how to interpret the Kinect data stream in order to drive your own software and hardware applications, including robotics applications

What you'll learn

  • How to create a software environment and connect to the Kinect from your PC
  • How to create three-dimensional images from the Kinect data stream
  • How to recognize and work around hardware limitations
  • How to build computer interfaces in the style of “Minority Report”
  • How to interact directly with objects in the virtual world
  • The ins and outs of point clouds, voxel occupancy maps, depth images, and other fundamentals of volumetric sensor technology

Who this book is for
Hacking the Kinect is aimed at makers of all types. Tech-savvy artists can use the Kinect to drive three-dimensional, interactive artwork. Robotics hobbyists can create robots capable of "seeing" and responding to human motion and gesture. Programmers can create applications in which users manipulate data through physical motion and gestures. The creative possibilities are limitless, and fun!

Hacking the Kinect does require some background. Familiarity with in ++ or similar languages is assumed. Readers should also be reasonably comfortable working with electronics—for example, with  or similar equipment.
