Verification and Validation in Scientific Computing, Oberkampf and Roy, 2010
Scientific computing is finding more uses in engineering and research. This book is about model verification. The questions are how well a simulation matches an actual activity, or how to get experimental data for a mathematics of micro- and nano-scales, and whether reviewers will find the results credible. Verification activities are shown for software, solution, model and management. Predictive capability is summarized in several steps for identifying sources of uncertainty, characterizing them, estimating error and uncertainty in the system response quantities (SRQs), updating the model, and analyzing sensitivities. There are five parts for sixteen chapters, and an appendix.

The internet remains a magnet for progress as it offers automated sports analysis, contextual intelligence, faster 32nm processor, datamining source code, a database of things, a social browser, social books, and a spaceship sim. Robotics is used as a home guard and actress. Sustainability makes a grand challenge. Comp sci invites philosophy. There are A/R glasses, hybrid Eurocopter, and floating city.
Good ideas are likely those that connect to eachother. Upon investigation of many events, myths had to be debunked. The author defines seven patterns of innovation and how they relate, including the Adjacent Possible, Liquid Networks, The Slow Hunch, Serendipity, Error, Exaptation, Platforms. A four quadrant diagram is used to classify breakthroughs as market, non-market, individual, or network. An appendix lists the major innovations of the previous six centuries.

User Stories Applied, Mike Cohn, 2004
This approach is from Agile User-Centered Design. Stories can also be added to Scrum. Extreme programming, XP, centers on testing, automated and acceptance. The testing is for usability, performance and stress rather than code coverage. There are various techniques used for developing the stories. They are modular for estimation and testability. A case is shown for a workshop having user role cards and story cards. A story card is a reminder of features to discuss. Each bug report is considered its own story. The planning game customer prioritizes their user story cards for the next iteration after developers have indicated the effort estimations for each. Tests are prepared prior to the code. Stories are grouped. A paper prototype is created and refined before programming begins. The UI is postponed for as long as possible. User goals can be listed from which stories will be derived. Burndown charts are used to track iteration hours. Another measure of momentum is the number of story points over time where each is an estimate for an ideal workday. The term smells is used for problems between participants, e.g. customer won’t do the stories, for which solutions are proposed. There are four parts beside an appendix on extreme programming. Each has a chapter summary, responsibilities of the developer and customer, and questions.
