Coding und Making mit Scratch und MakeyMakey
Scratch ist eine visuelle Programmiersprache, sie wurde von der Lifelong Kindergarten Group am MIT entwickelt. Viele neuere erziehungsorientierte Programmiersprachen nehmen sich das Design von Scratch als Vorbild (Snap!, Ozoblockly, Touchdevelop).Scratch ist so einfach in der Bedienung, dass bereits Volksschulkinder damit erste Erfahrungen im Programmieren machen können. Scratch läuft ab Version 2 im Browser, eine Installation ist nicht nötig. Die einzelnen Befehle werden per Drag & Drop zu Sequenzen verbunden, eine kindgerechte Bedienung steht im Vordergrund. Die Projekte werden online gespeichert und können veröffentlicht werden, so sind erste Ergebnisse schnell online verfügbar, aber auch ein lokales Speichern ist möglich.Mit Beiträgen von Bernhard Abfalter, Sabine Apfler, Moritz Brinnich, Elieser Grill, Duy Ho David Tran, Natalie Traxler und Andreas Weiner.Gerhard Brandhofer:HS-Prof. Mag. Dr. Gerhard Brandhofer, BEd hat eine Hochschulprofessur für Mediendidaktik und informatische Bildung an der PH Niederösterreich inne. Zu den Arbeitsschwerpunkten gehören die Planung, Lehre und Forschung im Bereich des Einsatzes von digitalen Medien im Unterricht der Primar- und Sekundarstufe Forschungsaktivitäten und Veröffentlichungen umfassen die Themenfelder der Nutzung digitaler Medien in der Schule wie auch in der Hochschule, die Bedingungen für gelingende informatische Bildung, die Implementierung visueller Programmiersprachen in der Schulbildung.

Seit vielen Jahren das unverzichtbare Standardwerk. Jetzt in 3., aktualisierter und überarbeiteter Auflage aus Februar 2023. TCP/IP gilt als Standard für die Kommunikation in Netzwerken – sowohl im lokalen Bereich als auch im weltumspannenden Internet. Wie jede Protokollfamilie so setzt sich auch TCP/IP aus verschiedenen Komponenten zusammen. Sie werden im Rahmen dieses Buches mit folgenden Schwerpunktthemen umfassend erläutert:Entwicklung und Funktion von NetzwerkenSwitching und RoutingProtokolle der TCP/IP-FamilieAdressierung im Netzwerk (statisch, dynamisch per DHCP)Namensauflösung im IP-Netzwerk (Domain Name Service)Routing-Protokolle im IP-Netzwerk und deren FunktionSpezielle Dienste auf Basis von TCP/IPTCP/IP in kabellosen Netzwerken (WLAN, Bluetooth, DSL-Vectoring usw.)Sicherheit im IP-Netzwerk (IPsec, VPN, SSL)Weiterentwicklungen auf Basis von IPv6Internet der Dinge (IoT)Implementierung von TCP/IP in BetriebssystemenNeben den Grundlagen werden auch praktische Aspekte beleuchtet, die für die tägliche Arbeit von Relevanz sein können. So wird beispielsweise der Analyse von Netzwerkstörungen ein ganzes Kapitel gewidmet. Außerdem wird beispielhaft im Anhang die TCP/IP-Konfiguration auf verschiedenen Betriebssystemplattformen dargestellt oder zum Thema »Sicherheit« ein datenzentrisch abgesicherter »Sicherheitsschild« vorgestellt.Zum Autor:Gerhard Lienemann arbeitete ab 1991 für etwa 12 Jahre als Netzwerkadministrator in einem produzierenden Betrieb, bevor er ins technische Management wechselte. Seitdem war er zunächst zuständig für operative Kommunikationssicherheit und übernahm dann zusätzlich die Betreuung eines europäischen Netzwerkteams. Nur kurze Zeit später erweiterte er seine Verantwortung auf ein globales Netzwerkteam in Asien, Nord- und Südamerika. Seiner Leidenschaft „IT-Kommunikation“ ist er auch nach dem Ausscheiden aus dem aktiven Berufsleben treu geblieben.

IT-Governance
Ordnungsrahmen und Handlungsfelder für eine erfolgreiche Steuerung der Unternehmens-ITDas Werk behandelt sowohl Grundsätzliches zu IT-Governance als auch die einzelnen Handlungsfelder der IT-Governance im Detail. Dabei geht die Darstellung insbesondere über die weit verbreitete GRC-Fokussierung hinaus. Dies führt dazu, dass die Gebiete der IT-Governance integriert dargestellt werden, so wie dies in der Praxis auch erforderlich ist. Insofern befasst sich das Buch neben der grundlegenden Darstellung der IT-Governance mit den Stakeholdern der IT-Governance und der Governance-Verantwortung in den Bereichen der Organisation der Unternehmens-IT, der IT-Risiken, der IT-Compliance, der Data Governance, des Wertbeitrags der IT, dem Business/IT-Alignment und der IT-Sicherheit. Auch auf für IT-Governance relevante Normen und Standards (ISO 38500, COBIT etc.) wird kontinuierlich Bezug genommen. Vor allem wird immer wieder die Schnittstelle zwischen IT-Governance und IT-Management dargestellt, sodass klar zwischen Governance- und Managementverantwortung unterschieden wird.Autoren:Prof. Dr. Michael Klotz ist seit 1999 Professor für Betriebswirtschaftslehre, insb.

Apple Device Management
Working effectively with Apple platforms at a corporate or business level includes not only infrastructure, but a mode of thinking that administrators have to adopt to find success. A mode of thinking that forces you to leave 30 years of IT dogma at the door. This book is a guide through how to integrate Apple products in your environment with a minimum of friction. Because the Apple ecosystem is not going away.You'll start by understanding where Apple, third-party software vendors, and the IT community is taking us. What is Mobile Device Management and how does it work under the hood. By understanding how MDM works, you will understand what needs to happen on your networks in order to allow for MDM, as well as the best way to give the least amount of access to the servers or services that’s necessary. You'll then look at management agents that do not include MDM, as well as when you will need to use an agent as opposed to when to use other options. Once you can install a management solution, you can deploy profiles on a device or you can deploy profiles on Macs using scripts.With Apple Device Management as your guide, you'll customize and package software for deployment and lock down devices so they’re completely secure. You’ll also work on getting standard QA environments built out, so you can test more effectively with less effort.This thoroughly revised and expanded Second Edition provides new coverage and updates on daemons and agents, declarative management, Gatekeeper, script options, SSO tools, Azure/Apple Business Essentials integrations and much more.YOU WILL* Deploy profiles across devices effectively and securely* Install apps remotely both from the app store and through custom solutions* Work natively with Apple environments rather than retrofitting older IT solutionsWHO THIS BOOK IS FORMac administrators within organizations that want to integrate with the current Apple ecosystem, including Windows administrators learning how to use/manage Macs, mobile administrators working with iPhones and iPads, and mobile developers tasked with creating custom apps for internal, corporate distribution.CHARLES EDGE is the Director of the Marketplace at Jamf.

Building With Ethereum
Build products on top of Ethereum's new and expansive technological stack.Writing any good web application requires planning, care, and deft technical skills, but Ethereum's execution model presents its own challenges for engineers wishing to build applications on top of its smart contract layer. Building performant and engaging product experiences is one of the most important – and often underappreciated – roles in any company.This book looks at the full product stack needed to build such experiences on top of Ethereum smart contracts, weaving tutorials and case studies through more conversational discussions of the various constraints, trade-offs, and complexities involved in doing so. You’ll learn about the fundamentals of Ethereum from a new perspective, developing a strong understanding of how the Ethereum Virtual Machine (EVM) works and how it affects product engineering, as well as all the pieces of technology that go into decentralized apps (dapps) behind the front end: RPC nodes, wallets, indexers, application hosts, and more. You’ll be exposed to plenty of UI, JavaScript code, and idiomatic ways to bring on-chain data into your front ends. And you’ll be given up-to-date knowledge of the best practices and future possibilities that decentralized computation might offer the product engineer.WHAT YOU WILL LEARN* Understand the EVM and how it works* Gain insight into smart contracts and how apps connect to them* Understand the difference between live data and indexed data* How decentralization affects the UI of applications* Build engaging, tasteful product experiences on top of EthereumWHO THIS BOOK IS FORA confident – mid-level or senior – software engineer or web developer who hasn’t properly branched out into Ethereum; someone who might have scratched the surface, but wants a deeper understanding of the principles behind dapps, and who wants a head start on the hurdles faced while building them.JAMIE RUMBELOW is a software engineer and writer based in London, U.K. Until recently, he was a product engineer at Fei Labs, a major Ethereum protocol, where he built technologies and products at the intersection between the web2 and web3 stacks. He worked as a Founding Engineer and Senior Software Engineer in startups, responsible for training and mentoring as well as writing code. He has worked in the tech industry for over a decade, seeing organizations at varying levels of scale and the ways that teams and technologies get shaped by product decisions. He has also studied philosophy at the graduate level, which has given him the tools to think about computing in a deeper way. Over the past few years, he has built up a set of principles and opinions on what makes for great software and a great engineering culture.CHAPTER 1. INTRODUCTIONWe introduce the core concepts discussed in the book, and situate them with respect to the foundational principles of cryptocurrencies and web3. We discuss decentralisation. We describe the key design decisions of the EVM (Ethereum Virtual Machine) and how they raise some problems for product engineers. We describe the book ahead and what will be covered, chapter by chapter.CHAPTER 2. THE LIFECYCLE OF AN ETHEREUM TRANSACTIONWe discuss the lifecycle of a request on Ethereum, guiding the user through: how is a request initiated by a UI and confirmed by a user; sent to a node, validated, how can UIs display its status, when is a transaction confirmed. We ask: what is a smart contract? We frame smart contracts as APIs. We also set up the following three chapters with the tripartite structure of write, read, and side-effect.CHAPTER 3. WALLETSWe discuss the role of wallets as both stores and signers. We discuss the popular MetaMask model for wallet injection, WalletConnect, EIP-1193, and other attempts to standardise the wallet interface. We explore wallets as identities, and describe approaches to 'logging in' with Ethereum. We explore different attack vectors that integrating wallets might raise.CHAPTER 4. NODES AND INDEXESWe talk about nodes – the programmatic gateway to the blockchain – in more detail: how to connect to them and use them to retrieve information. We discuss the difference between live data and indexed data. We discuss how external RPC nodes allow external function calls with and friends. We discuss ABIs and contract interfaces.CHAPTER 5. EVENTSWe investigate Ethereum's event model, and how to reconstruct a contract's state from the event log. We talk about Bloom filters and how to process many events efficiently.CHAPTER 6. TRANSACTIONSThis chapter builds more on the first chapter, diving into detail about the implementation of transactions. We discuss interfaces for creating, signing, and viewing transactions. We frame transactions theoretically and practically. We discuss the RPC call and its interface. We break down the minutiae of cryptographic signing and nonces, and consider how it affects the UI of applications. We discuss transaction statuses and estimation.CHAPTER 7. ERROR HANDLINGIn this chapter, we discuss the various failure modes of smart contracts and how to build rich, useful user interfaces around them. We consider gas, nonces, and transaction synchronisation. We talk about ways of building error-resilience into your product with input validation. We talk about standardising error messages at the smart contract level.CHAPTER 8. TOOLINGIn this chapter, we investigate the sorts of tools available to the product engineer, drawing on problems faced in the previous chapters. We discuss running manual tests, declarative provisioning of infrastructure, and keeping private keys safe. We also discuss current lacunas and places where existing tooling could be improved.CHAPTER 9. DATA-FIRST APPLICATIONSWe wrap-up the preceding discussion with a more opinionated chapter on a data-first approach to application design. In particular, I'll make the case for single-page applications backed by a data scraper as a strong model for building application infrastructure around smart contracts, tying together the themes of the preceding few chapters.CHAPTER 10. CONCLUSION: SMART CONTRACTS, SMARTER PRODUCTSWe discuss the ways that the surface area of smart contracts rubs against the surface area of web applications, with an emphasis on the more commercial and conceptual. We explore how detaching state from interface allows for more decentralised and censorship-resistant protocols – and how product engineers can profit from this split. We talk about the many ways that thoughtful product engineering can improve the user experience of crypto, and ruminate on the future direction of the ecosystem.Appendix 1: A Common-Sense Crypto-Native ChecklistWe provide a summary of the main questions and action points found in the book, with an easy reference checklist for engineers to work through when building their crypto-native applications.Appendix 2: Resources and BibliographyWe provide one or two pages of QR codes, with links to relevant resources. We provide a more comprehensive, traditional bibliography.
iOS Architecture Patterns
Develop well-structured applications using tested techniques and patterns. When you start to develop an application, you not only have to think about the idea of the finished application, but also about how it will evolve as it is built. This book shows you how to plan for changes, scope creep, and for the possibility of other developers joining in.Start by learning what architecture patterns for an application are. You’ll find out why it’s important for your applications to be based on these patterns and which ones are the most common. Then you’ll look at the MVC as one of the best known and used patterns. You’ll see how and when it can be implemented in your applications, as well as its advantages and disadvantages.From there, you’ll discover the first evolution of the MVC model: the MVP, which introduces a new layer (Presenter) to better manage views. The next evolution after that is the MVVM, which introduces the ViewModel layer and its connection with the views through Data Binding. With those prominent patterns covered, you’ll read about VIPER and VIP, Architecture Patterns that seeks to make applications easily maintainable, modularized, and highly scalable. All of which are hallmarks of Clean Architecture.Architecture patterns have developed and evolved to give your applications solid foundations. Understanding these patterns, you will reduce the problems that may arise when modifying existing functions, adding new ones, or correcting errors that may arise in the development process.WHAT YOU'LL LEARN* Code cleanly with solid foundations* Start your project ready to adapt and evolve as features and other developers are added* Find and apply the right patterns for the best results WHO THIS BOOK IS FORDevelopers with some programming knowledge who want to learn different architecture patterns, those who already have more experience and are looking for a starting point on complex patterns such as VIPER or VIP, and beginner programmersRAÚL FERRER GARCÍA holds a doctorate in Chemistry and started short-circuiting computer science by programming with a ZX Spectrum when he was 14. For the past decade as a Mobile Tech Lead, he has dedicated himself completely to the development and management of mobile applications for iOS. He also maintains a blog in which he tries to explain everything he’s learned and studied about the world of mobile development.1. Introduction1.1. What are architecture patterns?1.2.
