Delphi Quick Syntax Reference
The Delphi Quick Syntax Reference is a succinct code and syntax reference guide to Delphi. It presents the fundamental knowledge to get newcomers started with the language and provides a refresher to seasoned or returning Delphi developers.It covers all the new features added by Embarcadero during the last few years. Delphi celebrates 25 years in 2020 and, alongside the free community version that was introduced a couple of years ago, this syntax guide is a great way to get into the language.WHAT YOU WILL LEARN* Quickly use and learn Delphi* Compile, build and run a Delphi program* Master Delphi strings, variables, constants, and operators and how to apply them* Use conditions, loops, procedures, and functions in Delphi * Apply object-oriented programming in Delphi WHO THIS BOOK IS FORReturning or current Delphi developers: The book is a resource for reference for this group of developers especially for the new features that were introduced in the language over the last couple of years. Newcomers to the language: These developers will learn the fundamentals of the language in a very condensed and effective text that accelerates learning. John Kouraklis started exploring computers when he was 16 and since then has followed all the way from Turbo Pascal to Delphi and Delphi Tokyo as a hobby initially and as a profession for most of his adult life. He has developed a wide range of applications, from financial software to reverse engineering tools, including an application for professional gamblers.He is part of the Delphi community and participates in online communities, forums, and many other events. For example, he is active on Delphi Praxis, which is perhaps the biggest English-speaking online forum about Delphi. John also has a personal website where he posts articles regularly. Lastly, he has written two books about Delphi published by Apress.Chapter 1: Introduction to DelphiChapter 2: Anatomy of a Delphi programChapter 3: Compiling, Building and Running a program (including cross platform environments)Chapter 3: Variables, Constants and OperatorsChapter 4: StringsChapter 5: Conditionals and LoopsChapter 6: Procedures and FunctionsChapter 7: OOP in DelphiChapter 8: Enhancements (Anonymous Methods, etc.)

Blended Learning mit Moodle
BLENDED LEARNING MIT MOODLE - Moodle-Infrastruktur aufbauen und verstehen- Moodle professionell verwalten- Kurse gestalten und in das Unterrichtsprogramm integrieren- Unterstützender Einsatz von Hot Potatoes und H5P im Präsenzunterricht- Erfolgreich und zuverlässig Prüfungen mit Moodle durchführenBei „Moodle“ bzw. „E-/Blended Learning“ geht es vor allem darum, gezielt Kurse zu entwickeln, die sich ideal in das didaktische Konzept der Lehre integrieren und diese unterstützen. Auch die Durchführung von Prüfungen und Lernzielkontrollen sowie die Abgabe von Hausaufgaben sind ein wichtiges Thema. Das Lehrpersonal und der menschliche Kontakt sollen dadurch aber nicht ersetzt werden.Vorbereitende Übungen zur Vertiefung des Stoffs sollen kurzweilig gestaltet und auch für kurze Übungssequenzen geeignet sein. Einen Einblick in externe Software, die über den SCORM-Standard (Sharable Content Object Reference Model) in Moodle integriert werden kann, gibt die Vorstellung von Hot Potatoes. In der Zukunft wird für die Unterstützung der Präsenzlehre und der Fernschulung sowie als motivierendes Recherchemedium die Integration multimedialer, interaktiver Technologien wie H5P in Moodle immer wichtiger.Blended-Learning-Technologien (hier am Beispiel des am weitesten verbreiteten LMS Moodle) sollen eine Unterstützung der Aus- und Fortbildung sein, nicht jedoch als eine disruptive Konkurrenz zu einer zwischenmenschlich geprägten Pädagogik aufgefasst werden. Dazu soll dieses Werk beitragen.AUS DEM INHALTTeil I - Allgemeine Ansätze- Potenzielle Zielgruppen- Potenzielle EinsatzbereicheTeil II – Technik- Der Moodle-Server- Moodle-Grundinstallation- Benutzerverwaltung- Rollen im Moodle-System- Bereichs- und Kursverwaltung- E-Mail-Kommunikation- DesignsTeil III - Moodle in der Praxis- Moodle im Überblick- Aktivitäten - Werkzeuge zur Kursgestaltung- Ergänzende Lernhilfen für Moodle- Fragenkataloge in Moodle- Lernzielkontrollen und Prüfungen

Clean Agile - Deutsche Ausgabe
Die Essenz der agilen SoftwareentwicklungZurück zu den Ursprüngen: Die agilen Werte und Prinzipien effektiv in der Praxis umsetzen Lernen Sie aus Uncle Bobs jahrzehntelanger Erfahrung, worauf es bei der agilen Softwareentwicklung wirklich ankommt Die ursprünglichen agilen Werte und Prinzipien kurz und prägnant für den Praxiseinsatz erläutert Von den unternehmerischen Aspekten über die Kommunikation im Team bis zu den technischen Praktiken wie Test-Driven Development (TDD), einfaches Design und Pair Programming Fast 20 Jahre nach der Veröffentlichung des agilen Manifests ruft der legendäre Softwareentwickler Robert C. Martin (»Uncle Bob«) dazu auf, sich wieder auf die ursprünglichen Werte und Prinzipien zurückzubesinnen, die den eigentlichen Kern der agilen Softwareentwicklung ausmachen und die für die Praxis von zentraler Bedeutung sind. Mit Clean Agile lässt er alle an seiner jahrzehntelangen Erfahrung teilhaben und räumt mit Missverständnissen und Fehlinterpretationen auf, die im Laufe der Jahre entstanden sind. Dabei wendet er sich gleichermaßen an Programmierer und Nicht-Programmierer. Uncle Bob macht deutlich, was agile Softwareentwicklung eigentlich ist, war und immer sein sollte: ein einfaches Konzept, das kleinen Softwareteams hilft, kleine Projekte zu managen – denn daraus setzen sich letztendlich alle großen Projekte zusammen. Dabei konzentriert er sich insbesondere auf die Praktiken des Extreme Programmings (XP), ohne sich in technischen Details zu verlieren. Egal, ob Sie Entwickler, Tester, Projektmanager oder Auftraggeber sind – dieses Buch zeigt Ihnen, worauf es bei der Umsetzung agiler Methoden wirklich ankommt. Aus dem Inhalt: Ursprünge der agilen Softwareentwicklung Agile Werte und Prinzipien Der richtige Einsatz von Scrum Agile Transformation Extreme Programming Unternehmensbezogene Praktiken: User Stories, Velocity, kleine Releases und Akzeptanztests Teambezogene Praktiken: gemeinsame Eigentümerschaft, kontinuierliche Integration und Stand-up-Meetings Technische Praktiken: TDD, Refactoring, einfaches Design und Pair Programming Zertifizierung und Coaching Software Craftsmanship

Clean Agile. Die Essenz der agilen Softwareentwicklung
* LERNEN SIE AUS UNCLE BOBS JAHRZEHNTELANGER ERFAHRUNG, WORAUF ES BEI DER AGILEN SOFTWAREENTWICKLUNG WIRKLICH ANKOMMT* DIE URSPRÜNGLICHEN AGILEN WERTE UND PRINZIPIEN KURZ UND PRÄGNANT FÜR DEN PRAXISEINSATZ ERLÄUTERT* VON DEN UNTERNEHMERISCHEN ASPEKTEN ÜBER DIE KOMMUNIKATION IM TEAM BIS ZU DEN TECHNISCHEN PRAKTIKEN WIE TEST-DRIVEN DEVELOPMENT (TDD), EINFACHES DESIGN UND PAIR PROGRAMMINGFast 20 Jahre nach der Veröffentlichung des agilen Manifests ruft der legendäre Softwareentwickler Robert C. Martin (»Uncle Bob«) dazu auf, sich wieder auf die ursprünglichen Werte und Prinzipien zurückzubesinnen, die den eigentlichen Kern der agilen Softwareentwicklung ausmachen und die für die Praxis von zentraler Bedeutung sind. Mit Clean Agile lässt er alle an seiner jahrzehntelangen Erfahrung teilhaben und räumt mit Missverständnissen und Fehlinterpretationen auf, die im Laufe der Jahre entstanden sind. Dabei wendet er sich gleichermaßen an Programmierer und Nicht-Programmierer.Uncle Bob macht deutlich, was agile Softwareentwicklung eigentlich ist, war und immer sein sollte: ein einfaches Konzept, das kleinen Softwareteams hilft, kleine Projekte zu managen - denn daraus setzen sich letztendlich alle großen Projekte zusammen. Dabei konzentriert er sich insbesondere auf die Praktiken des Extreme Programmings (XP), ohne sich in technischen Details zu verlieren.Egal, ob Sie Entwickler, Tester, Projektmanager oder Auftraggeber sind - dieses Buch zeigt Ihnen, worauf es bei der Umsetzung agiler Methoden wirklich ankommt.AUS DEM INHALT:* Ursprünge der agilen Softwareentwicklung* Agile Werte und Prinzipien* Der richtige Einsatz von Scrum* Agile Transformation* Extreme Programming* Unternehmensbezogene Praktiken: User Stories, Velocity, kleine Releases und Akzeptanztests* Teambezogene Praktiken: gemeinsame Eigentümerschaft, kontinuierliche Integration und Stand-up-Meetings* Technische Praktiken: TDD, Refactoring, einfaches Design und Pair Programming* Zertifizierung und Coaching* Software CraftsmanshipSTIMMEN ZUM BUCH:»Bobs Frustration spiegelt sich in jedem Satz des Buchs wider - und das zu Recht. Der Zustand, in dem sich die Welt der agilen Softwareentwicklung befindet, ist nichts im Vergleich zu dem, was sie eigentlich sein könnte. Das Buch beschreibt, auf was man sich aus Bobs Sicht konzentrieren sollte, um das zu erreichen, was sein könnte. Und er hat es schon erreicht, deshalb lohnt es sich, ihm zuzuhören.«- Kent Beck»Uncle Bob ist einer der klügsten Menschen, die ich kenne, und seine Begeisterung für Programmierung kennt keine Grenzen. Wenn es jemandem gelingt, agile Softwareentwicklung zu entmystifizieren, dann ihm.«- Jerry FitzpatrickRobert C. Martin (»Uncle Bob«) ist bereits seit 1970 als Programmierer tätig. Neben seiner Beraterfirma Uncle Bob Consulting, LLC gründete er gemeinsam mit seinem Sohn Micah Martin auch das Unternehmen The Clean Coders, LLC. Er hat zahlreiche Artikel in verschiedenen Zeitschriften veröffentlicht und hält regelmäßig Vorträge auf internationalen Konferenzen.

Advanced Python Development
This book builds on basic Python tutorials to explain various Python language features that aren’t routinely covered: from reusable console scripts that play double duty as micro-services by leveraging entry points, to using asyncio efficiently to collate data from a large number of sources. Along the way, it covers type-hint based linting, low-overhead testing and other automated quality checking to demonstrate a robust real-world development process.Some powerful aspects of Python are often documented with contrived examples that explain the feature as a standalone example only. By following the design and build of a real-world application example from prototype to production quality you'll see not only how the various pieces of functionality work but how they integrate as part of the larger system design process. In addition, you'll benefit from the kind of useful asides and library recommendations that are a staple of conference Q&A sessions at Python conferences as well as discussions of modern Python best practice and techniques to better produce clear code that is easily maintainable.Advanced Python Development is intended for developers who can already write simple programs in Python and want to understand when it’s appropriate to use new and advanced language features and to do so in a confident manner. It is especially of use to developers looking to progress to a more senior level and to very experienced developers who have thus far used older versions of Python.WHAT YOU'LL LEARN* Understand asynchronous programming* Examine developing plugin architectures* Work with type annotations* Review testing techniques* Explore packaging and dependency managementWHO THIS BOOK IS FORDevelopers at the mid to senior level who already have Python experience.Matthew Wilkes is a European software developer who has worked with Python on web projects for the last fifteen years. As well as developing software, he has long experience in mentoring Python developers in a commercial setting.He is also very involved in open source software, with commits to many popularframeworks. His contributions in that space are focused on the details of database and security interactions of web frameworks.Chapter 1: Prototyping and EnvironmentsChapter Goal: Create a prototype script to read a single sensor valueNo of pages 25Sub -Topics1 Introduce the example of collating data from a large number of othermachines1.1 Possible usecases of this pattern include log aggregation, servermonitoring, IoT, monitoring of customer servers, etc1.2 We’ll use raspberry pis with a mix of server monitoring andvery basic sensors like temperature sensors.

Attribution of Advanced Persistent Threats
An increasing number of countries develop capabilities for cyber-espionage and sabotage. The sheer number of reported network compromises suggests that some of these countries view cyber-means as integral and well-established elements of their strategical toolbox. At the same time the relevance of such attacks for society and politics is also increasing. Digital means were used to influence the US presidential election in 2016, repeatedly led to power outages in Ukraine, and caused economic losses of hundreds of millions of dollars with a malfunctioning ransomware. In all these cases the question who was behind the attacks is not only relevant from a legal perspective, but also has a political and social dimension.Attribution is the process of tracking and identifying the actors behind these cyber-attacks. Often it is considered an art, not a science.This book systematically analyses how hackers operate, which mistakes they make, and which traces they leave behind. Using examples from real cases the author explains the analytic methods used to ascertain the origin of Advanced Persistent Threats.DR. TIMO STEFFENS was involved in the analysis of many of the most spectacular cyber-espionage cases in Germany. He has been tracking the activities and techniques of sophisticated hacker groups for almost a decade.Advanced Persistent Threats.- The attribution process.-Analysis of malware.- Attack infrastructure.- Analysis of control servers.- Geopolitical analysis.- Telemetry - data from security products.- Methods of intelligence agencies.- Doxing.- False flags.- Group set-ups.- Communication.- Ethics of attribution.

Advanced R 4 Data Programming and the Cloud
Program for data analysis using R and learn practical skills to make your work more efficient. This revised book explores how to automate running code and the creation of reports to share your results, as well as writing functions and packages. It includes key R 4 features such as a new color palette for charts, an enhanced reference counting system, and normalization of matrix and array types where matrix objects now formally inherit from the array class, eliminating inconsistencies.Advanced R 4 Data Programming and the Cloud is not designed to teach advanced R programming nor to teach the theory behind statistical procedures. Rather, it is designed to be a practical guide moving beyond merely using R; it shows you how to program in R to automate tasks.This book will teach you how to manipulate data in modern R structures and includes connecting R to databases such as PostgreSQL, cloud services such as Amazon Web Services (AWS), and digital dashboards such as Shiny. Each chapter also includes a detailed bibliography with references to research articles and other resources that cover relevant conceptual and theoretical topics.WHAT YOU WILL LEARN* Write and document R functions using R 4* Make an R package and share it via GitHub or privately* Add tests to R code to ensure it works as intended* Use R to talk directly to databases and do complex data management* Run R in the Amazon cloud* Deploy a Shiny digital dashboard* Generate presentation-ready tables and reports using RWHO THIS BOOK IS FORWorking professionals, researchers, and students who are familiar with R and basic statistical techniques such as linear regression and who want to learn how to take their R coding and programming to the next level.MATT WILEY leads institutional effectiveness, research, and assessment at Victoria College, facilitating strategic and unit planning, data-informed decision making, and state/regional/federal accountability.
