Troubleshoot and Optimize Complex, Time-Constrained Software From mobile and cloud apps to video games to driverless vehicle control, more and more software is time-constrained: It must deliver reliable results seamlessly, consistently, and virtually instantaneously. If it doesn't, customers are unhappy--and sometimes lives are put at risk. When time-constrained software underperforms or fails, software professionals must quickly identify and address the root causes. This is difficult and, historically, few tools have been available to help. In Understanding Software Dynamics, performance expert Richard L. Sites tackles the problem head on, offering expert methods and advanced tools for understanding complex time-constrained software dynamics, improving reliability, and troubleshooting challenging performance problems. Sites draws on several decades of experience pioneering software performance optimization, as well as extensive experience teaching graduate-level developers. He introduces principles and techniques for use in any environment, from embedded devices to datacenters, illuminating them with examples based on x86 or ARM processors running Linux and linked by Ethernet. He also guides readers through building and applying a powerful, new, extremely low-overhead open-source software tool, KUtrace, to precisely trace executions on every CPU core. Using insights gleaned from this tool, readers can apply nuanced solutions--not merely brute-force techniques such as turning off caches or cores. Measure and address issues associated with CPUs, memory, disk/SSD, networks, and their interactions Fix programs that are always too slow, and those that sometimes lag for no apparent reason Design useful observability, logging, and time-stamping capabilities into your code Reason more effectively about performance data to see why reality differs from expectations Identify problems such as excess execution, slow instruction execution, waiting for resources, and software locks Understanding Software Dynamics will be valuable to experienced software professionals, including application and OS developers, hardware and system architects, real-time system designers, and game developers, as well as advanced students.

Make your foray into successive approximations successful and as easy as possible. In the 2012 bestseller, Leaving ADDIE for SAM, learning professionals were introduced to the Successive Approximation Model (SAM) and the Savvy Start--the key to a successful project kick-off. Together, these concepts incorporate contemporary Agile processes that simplify design and development, yielding more energetic and effective learning experiences. This companion Field Guide provides the job aids, tools, and templates you need to put the SAM methodology in motion and take your ISD practice to new heights. Complete with a foreword by Michael Allen, this book is an essential resource to create better, faster training products and "move the needle" on current training efforts. In this book, you will: * Apply the principles and concepts behind Leaving ADDIE for SAM. * Update your training products with these contemporary, Agile design processes. * Use the job aids, tools, and templates provided to work on actual projects.

Guidelines and Templates for Developing the Best Learning Experiences

Leaving Addie for Sam Field Guide

You're a business leader. An executive. You speak the language of finance. Of operational excellence. Of marketing and customer opportunities. And more than anything, your work is about producing revenues and increasing profits. Your training department, meanwhile, speaks the language of instructional processes and design strategies. They use phrases like "waterfall development," "needs analysis," and "learning objectives." But really, they want the same thing as you - effective training that provides the strongest return on their effort and ideas. This disconnect is a big problem in many organizations, because training is one of few functions that affects every part of your company. When business strategy and training are out of alignment, resources get wasted. The bottom line suffers. And, worst of all, people stop improving. In UPTRAIN, Dr. Richard Sites, an expert in transforming training into operational excellence, provides a unique and sensible strategy (The Power Formula) that bridges the divide between the executive and the trainer. It's a handbook for business leaders who want to maximize the power of training, improve the performance of their employees, and supercharge the company's bottom line.
