How to get Instant Overview
Often, Excel is used to evaluate given data. Which values are critical? Can I see at a glance what the development was like? Can I highlight a whole row if one column has important content? Or ask for the content of two cells, simultaneously? How do I get overview in a thick workbook? How do I get a clear and telling chart? Can I ask Excel in natural language without any formula? All these questions are answered here.Ina Koys is an experienced instructor for Microsoft Office. Many questions are frequently asked in trainings, but seldom covered in books. Now she answers some of them in her originally German "short & spicy" series. A little accent will add to the fun :-)

How Open Source Ate Software
Learn how free software became open source and how you can sell open source software. This book provides a historical context of how open source has thoroughly transformed how we write software, how we cooperate, how we communicate, how we organize, and, ultimately, how we think about business values.This fully updated second edition includes an entire chapter on legal considerations such as trademarks and the latest happenings in open source licensing. It also expands on open hardware trends such as RISC-V, open governance, and the difference between community projects and commercial products, especially as seen through the lens of security.You’ll look at project and community examples including Linux, BSD, Apache, and Kubernetes, understand the open source development model, and how open source has influenced approaches more broadly, even within proprietary software, such as open betas. You'll also examine the flipside, the "Second Machine Age," and the challenges of open source-based business models.Today, open source serves as shorthand for much broader trends and behaviors. It’s not just about a free (in all senses of the word) alternative to commercial software. It increasingly is the new commercial software. How Open Source Ate Software, second edition reveals how open source has much in common, and is often closely allied, with many other trends in business and society. You'll see how it enables projects that go beyond any individual company. That makes open source not just a story about software, but a story about almost everything.WHAT YOU'LL LEARN* The opportunities that open source creates and the challenges that come with them* The ways in which companies can create business models to successfully sell "free" software* How the open source development model works from creating communities to selling commercial products* The important issues associated with open source project and product governance and licensing* How open source principles can apply more broadly to DevOps and other organizational practicesWHO THIS BOOK IS FORAnyone who is contemplating building a community and a business around open source software.GORDON HAFF is Red Hat technology evangelist, is a frequent and highly acclaimed speaker at customer and industry events, and helps develop strategy across Red Hat’s full portfolio of cloud solutions.

Modern Front-end Architecture
Learn how to build front-end applications that can help you ship applications faster with fewer defects. Many software projects fail because they are not planned well, or lack organization. Applying strategies from other industries can help you create better software. This book explores the “mise en place” technique from cooking and reveals how you can apply it to the art of creating software.In many professional kitchens, the work of preparing a meal is divided and performed in workstations to help create the whole. You'll review the philosophy behind this and see how to leverage this approach in your code. You'll also learn to visualize your applications as a series of components and build parts of your application in isolation - just like a professional chef crafting each part of the meal.The book describes to how to structure your code base for reuse, and how to communicate the code’s intent to other developers. You’ll develop your components in isolation and test these building blocks for quality at a granular level. Then compose these components as building blocks in increasingly complicated features. Finally, you’ll apply some strategies not directly related to code to ensure maximum quality and efficiency.With Modern Front-end Architecture, developers of all levels will learn strategies that they and their teams can leverage to be more productive.WHAT YOU'LL LEARN* Structure an application as a series of components* Build a component library that others in an organization can leverage* Ensure quality and accessibility at a component level rather than a page or app level* Test code in a way that gives the maximum amount of confidence while providing an excellent developer experience* Automate repeatable tasksWHO THIS BOOK IS FORFront end developers looking to maximize their code for reuse, quality, and shipping features quickly.

Der Zufall in Physik, Informatik und Philosophie
Zufall als Fundament der Welt, aus der Buchreihe "Die blaue Stunde der Informatik".Der Zufall ist uns unheimlich. Wir dachten, es gäbe ihn nicht, hinter allem stehe Gott oder eine vernünftige Erklärung. Aber wir wissen heute: Es gibt ihn. Wir wissen, dass vieles dessen, was uns umgibt und das wir nicht durchschauen, trotzdem kausal abläuft. Anders als zu Zeiten der Aufklärung gedacht, ist der Zufall um uns eher die Regel als die gesetzmäßige Ordnung. Die Wolken sind Fraktale, die Wellen auf dem Meer sind eine reine Zufallsmaschinerie. Der Philosoph Charles Peirce hat genau in diesem Sinn noch vor Quanten- und Chaostheorie die fundamentale Bedeutung des Zufalls erkannt und der Lehre ihren Namen gegeben: Tychismus.Ohne Zufall gäbe es nichts Neues, kein Leben, keine Kreativität, keine Geschichte.Dieses Buch betrachtet den Zufall aus Sicht der Physik, der Informatik und der Philosophie. Es spannt den Bogen von der Antike zur Quantenphysik und zeigt, dass der Zufall fest in die Welt eingebaut ist und es sie ohne Zufall nicht gäbe.Dr. Walter Hehl ist vielseitiger Physiker und Autor recht verschiedener Bücher zu IT, Management, Religion, Philosophie und zur Geschichte der Wissenschaft. Sein Buch über Galilei erhielt 2019 den Preis der Woitschach-Stiftung für das beste kritische, aber faire Wissenschaftsbuch.

Technology was changing fast and Gunnard rode the wave from 1200 to 56k baud modems. Logging in to BBSs, Prodigy, Compuserve, Delphi and IRC he could see the world changing and he wanted to be a part of it. He soon got involved in the ansi/demo scene, making several application generators for many groups in the 90’s. Visual Basic was the next language of choice allowing him to develop “tools” for online systems such as AOL. This introduced many aspects of development, security and UI while they were still in their infancy. Once the WWW arrived via Mindspring in Atlanta, Ga. Gunnard quickly joined in the race for the web. Learning HTML, PERL and Linux (Slackware at the time) he began to build his skill-set which lead to a full-time Sysadmin position at the age of 20 (2000) at Activegrams/Silverpop. Gunnard has moved around the IT industry from SAN/NAS storage at IBM to custom Wordpress sites for marketing companies, but one thing has stayed the same, a passion for learning and problem solving.

Patterns in the Machine
Discover how to apply software engineering patterns to develop more robust firmware faster than traditional embedded development approaches. In the authors’ experience, traditional embedded software projects tend towards monolithic applications that are optimized for their target hardware platforms. This leads to software that is fragile in terms of extensibility and difficult to test without fully integrated software and hardware. Patterns in the Machine focuses on creating loosely coupled implementations that embrace both change and testability.This book illustrates how implementing continuous integration, automated unit testing, platform-independent code, and other best practices that are not typically implemented in the embedded systems world is not just feasible but also practical for today’s embedded projects.After reading this book, you will have a better idea of how to structure your embedded software projects. You will recognize that while writing unit tests, creating simulators, and implementing continuous integration requires time and effort up front, you will be amply rewarded at the end of the project in terms of quality, adaptability, and maintainability of your code.WHAT YOU WILL LEARN* Incorporate automated unit testing into an embedded project* Design and build functional simulators for an embedded project* Write production-quality software when hardware is not available* Use the Data Model architectural pattern to create a highly decoupled design and implementation* Understand the importance of defining the software architecture before implementation starts and how to do it* Discover why documentation is essential for an embedded project* Use finite state machines in embedded projectsWHO THIS BOOK IS FORMid-level or higher embedded systems (firmware) developers, technical leads, software architects, and development managers.John Taylor has been an embedded developer for over 29 years.
