'Ways to Wander' is your invitation to experiment with a whole
range of different ways to 'go for a walk'. Rather than picking up
a map and following a footpath, the book offers 54 intriguingly
different suggestions, tactics and recollections, all submitted by
artists (most of them involved with the Walking Artists Network).
There are plenty of ideas you can just go out and try, but others
are more performative or explore the psychological, cultural and
philosophical aspects of walking Pop the book in your back pocket,
leave it in your rucksack, share it with friends and take them on a
walk, use it in creative workshops, read it as if each instruction
were poetry, engage with each page as visual art or as a
performance activity, let it remind you of places you've been or
walks you'd like to do. When the moment takes you, be inspired by
the variety of inventive and reflective ideas mapped out here and
then simply... wander.
An Expert Guide to Software Performance Optimization 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 complex software underperforms or fails, software
engineers need to 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.
