Beginning Programming Using Retro Computing - Gerald Friedland - Bog - APress - Plusbog.dk

Learn programming using the Commodore 16/Plus 4 system. Following this book, you and your children will not only learn BASIC programming, but also have fun emulating a retro Commodore system. There are many ways to bring the fun of learning to program in the 1980s back to life. For example, downloading the VICE emulator to a Raspberry Pi allows for the classic "turn on and program" experience and also provides some retro computing project fun. Many parents learned programming in this same way and can have fun helping their children follow the same path. You can also use this book as an opportunity to dust off your computing skills or learn programming concepts for the first time on a system that''s easy, approachable, and fun with a nostalgic twist. Commodore computers were the most sold computing devices before the iPhone. Nowadays, the Commodore system can be run using freely available emulation on modern computers. This book uses VICE, which is available for PC, Mac, Linux, as an online app, and on the Raspberry Pi. Beginning Programming Using Retro Computing offers simple programming concepts to give children and adults alike a sense of wonder in seeing that words they write have the power to do things, like play sounds, draw graphics, or finish math homework.

Performance Testing - Keith Yorkston - Bog - APress - Plusbog.dk

Use this book to prepare for the ISTQB® Certified Tester Foundation Level Performance Testing exam. The book has been designed to follow the ISTQB syllabus, covering all of the syllabus learning objectives, with additional reference material extending beyond the syllabus. The book covers an overall methodology for managing and conducting performance testing. Performance testing has often been considered a black art. In many organizations, perhaps an individual or a small group of technical staff or contractors is given the task of “load testing” an extended system, network, or application. Performance testing is like any other form of testing. It follows a defined test process that is similar to other test types. It utilizes a disciplined approach to the definition of requirements and user stories, the creation of test conditions, test cases, and test procedures. It establishes measurable goals against which the success or failureof the testing can be judged. It also requires (and this cannot be stressed highly enough) a definition and recognition of performance test failures. Readers will gain the knowledge with both content and practice questions to prepare them for the ISQTB Performance Testing exam. The book covers the performance test types, the performance testing methodology, and the steps to plan, create, and execute performance tests and analyze the results. What You Will LearnUnderstand the basic concepts of performance efficiency and performance testingDefine performance risks, goals, and requirements to meet stakeholder needs and expectationsUnderstand performance metrics and how to collect themDevelop a performance test plan for achieving stated goals and requirementsConceptually design, implement, and execute basic performance testsAnalyze the results of a performance test and communicate the implications to stakeholdersExplain the process, rationale, results, and implications of performance testing to stakeholdersUnderstand the categories and uses for performance tools and criteria for their selectionDetermine how performance testing activities align with the software life cycle Who This Book Is ForThose who want to achieve the ISTQB performance testing certification, testers and test managers who want to increase their performance testing knowledge, and project managers/staff working with performance testing in their project for the first time
