The Common Lisp Condition System
Discover the functioning and example uses of the Common Lisp condition system. This book supplements already existing material for studying Common Lisp as a language by providing detailed information about the Lisp condition system and its control flow mechanisms; it also describes an example ANSI-conformant implementation of the condition system.In part 1 of The Common Lisp Condition System, the author introduces the condition system using a bottom-up approach, constructing it piece by piece. He uses a storytelling approach to convey the foundation of the condition system, dynamically providing code to alter the behavior of an existing program. Later, in part 2, you’ll implement a full and complete ANSI-conformant condition system while examining and testing each piece of code that you write.Throughout, the author demonstrates how to extend Lisp using Lisp itself by using the condition system as an example. This is done while paying proper attention to the CL restart subsystem, giving it attention on a par with the handler subsystem. After reading and using this book, you'll have learned about the inner functioning of the condition system, how to use it in your own Common Lisp coding and applications, and how to implement it from scratch, should such a need arise.WHAT YOU WILL LEARN* Examine the condition system and see why it is important in Common Lisp* Construct the condition system from scratch using foundational mechanisms provided by Common Lisp* Program the condition system and its control flow mechanisms to achieve practical results* Implement all parts of a condition system: conditions, restarts, handler- and restart-binding macros, signalling mechanisms, assertions, a debugger, and moreWHO THIS BOOK IS FORBeginning and intermediate Lisp programmers, as well as intermediate programmers of other programming languages.MICHAŁ "PHOE" HERDA is a programmer with contributions to multiple parts of the Common Lisp ecosystem: CL implementations, existing and widely-used CL utilities, documentation, and some of the new library ideas that he slowly pushes forwards and works on. The book The Common Lisp Condition System is his first work -- an attempt to create a tutorial on the condition system that was missing, even all the years after which ANSI Common Lisp was standardized.1: Basic Concepts2: Introducing the Condition System3: Implementing the Common Lisp Condition System4: Wrapping UpAppendix A: Implementation of Dynamic Variables in CAppendix B: Additional Utilities for Working with Common Lisp ConditionsAppendix C: Lisp Macros 101Appendix D: Condition System Reference

Technisches Konstruieren mit OpenSCAD
Das Design dreidimensionaler Modelle mit Werkzeugen wie Blender oder 3D Studio Max ist eine Aufgabe, die ingenieurwissenschaftlich begabte Personen nur allzu gern delegieren.OpenSCAD wählt einen erfrischend anderen Zugang. Anstatt ein Objekt als Punktwolke zu betrachten, schreibt der Modellerzeuger in einer an Javascript erinnernden Sprache ein Programm. Dieses beschreibt die zu erzeugende Geometrie als eine Serie von Arbeitsschritten. Dreidimensionale Modelle entstehen so in einem Workflow, der an die Entwicklung klassischer ingenieurwissenschaftliche Güter erinnert. Wegen der Nähe zur manuellen Fertigung mit Werkzeug ist das ein Prozess, der Ingenieuren gut in die Hände spielt.Aber Achtung: trotz der Einfachheit der Syntax ist OpenSCAD kein primitives Modellierungsprogramm. Umfangreiche Scriptingmöglichkeiten sorgen dafür, dass sich die Modelle dynamisch an geänderte Situationen anpassen.Dieses Lehrbuch demonstriert die Möglichkeiten von OpenSCAD anhand praktischer Beispiele. Freuen Sie sich auf Ersatzknöpfe für ein LeCroy-Oszilloskop, Garderobenstangenhalter, einen Halter für Seifenspender und diverse andere Beispiele aus dem realen Leben.Der mit mehr als 15 Dienstjahren Erfahrung ausgestattete Autor entwickelte dieses für Linux und Windows gleichermaßen geeignete Buch explizit für informatikaffine Personen. Wenn Sie mit irgendeiner Programmiersprache Erfahrung haben, ist dieses Buch ihr Weg zum schnellen und unbürokratischen Erzeugen dreidimensionaler Modelle.Tam Hanna programmiert und entwickelt seit mehr als 15 Jahren Microcontroller und Prozessrechnersysteme für verschiedene Anwendungsfälle. Neben seiner Consultingtätigkeit hält er Vorträge auf Kongressen, verfasst Fachartikel für diverse Magazine und agiert als Tutor. Sein viel beachteter Instagram-Kanal liefert Hintergrundinformationen zu Messtechnik und Elektronik.

Welche KI?
Künstliche Intelligenz hat das Potenzial, viele Bereiche unseres Lebens grundlegend zu verändern. Dies betrifft unter anderem Veränderungen der Arbeitswelt, autonome Fahrzeuge oder sogar Waffen, das Gesundheitssystem, demokratische Gesellschaftsstrukturen und die gesamte Lebenswelt. Daraus erwachsen große Chancen für die Gesellschaft, aber auch große Gefahren.In der Analyse solcher Szenarien zeigt sich, dass die Auswirkungen von KI in einer ethischen Detailbetrachtung nicht ausreichend erfasst werden können. Vielmehr müssen sie aus einem umfassenden gesellschaftlichen und menschlichen Zusammenhang beurteilt werden. In diesem Buch wird daher eine Perspektive auf KI gezeigt, die ethische Detailfragen zu den Anwendungen von KI aus der größeren Perspektive philosophischer Reflexion betrachtet.Diese umfasst philosophische Überlegungen zur Auswirkung der Technik und die Betrachtung von Szenarien der Technikentwicklung. Weiterhin werden Veränderungen des Menschenbildes analysiert, die mit der Entwicklung von KI verbunden sind. Damit hängt die Frage zusammen, ob KI Bewusstsein entwickeln kann und ob einer fortgeschrittenen KI ein Rechtsstatus einer elektronischen Persönlichkeit zugeordnet werden soll.Die betrachteten Entwicklungsszenarien umfassen die Veränderung der Arbeitswelt zwischen einer Hoffnung auf eine Entlastung von monotonen und gefährlichen Tätigkeiten einerseits und der Gefahr von Massenarbeitslosigkeit andererseits. Weiterhin werden neben den bekannten Problemen des autonomen Fahrens die Auswirkungen auf Szenarien der Mobilität betrachtet. In Bezug auf den Einsatz von autonomen Waffen und auf die Steuerung der Kriegsführung durch KI wird das Szenario eines neuen Wettrüstens und einer Entgrenzung der Kriegsführung vorgestellt, das eine Ächtung dieser Techniken nahelegt.Für das Gesundheitssystem und die Altenpflege wird das Szenarium einer weiteren Entmenschlichung dieser Bereiche mit einem Konzept kontrastiert, das dem menschlichen Faktor gerade durch die Entlastung von technischen Aufgaben einen neuen Stellenwert gibt. Entsprechende Szenarien werden für die Auswirkungen von KI auf die Demokratie und die Durchdringung der Lebenswelt vorgestellt. Prof. Dr. Stefan Bauberger hat Philosophie, Theologie und Physik studiert. Er hat ein Diplom in Theologie, eine Promotion in theoretischer Physik und eine Habilitation in Philosophie erworben. Er ist an der Hochschule für Philosophie in München als Professor für Naturphilosophie und Wissenschaftstheorie tätig. Seit einigen Jahren liegt sein Schwerpunkt auf der Technikphilosophie, mit besonderer Ausrichtung auf die Künstliche Intelligenz.

C++ mit Visual Studio 2019 und Windows Forms-Anwendungen
C++ hat sich in den letzten Jahren rasant entwickelt: C++11, C++14, C++17 und C++20 haben viele Verbesserungen und neue Möglichkeiten gebracht. Vieles, was vor 10 Jahren noch gut und empfehlenswert war, kann heute besser und sicherer gemacht werden.Dieses Buch stellt C++ mit Visual Studio 2019 auf dem Stand von Mai 2020 umfassend dar. Das ist nicht nur der Umfang von C++17, sondern auch schon ein Teil von C++20.Es entstand aus zahlreichen Vorlesungen und Firmenseminaren. Dementsprechend richtet es sich einerseits an STUDIERENDE, die C++ lernen wollen. Der Aufbau, die vielen Beispiele und Übungsaufgaben sind erprobt und bewährt. Es eignet sich zum Selbststudium und als Lehrbuch für Vorlesungen an Fachhochschulen und Universitäten.Dieses Buch zeigt aber ebenso PROFESSIONELLEN SOFTWARE-ENTWICKLERN mit einer jahrelangen C++-Praxis den aktuellen Stand der Technik.

Learn PHP 8
Write solid, secure, object-oriented code in the new PHP 8. In this book you will create a complete three-tier application using a natural process of building and testing modules within each tier. This practical approach teaches you about app development and introduces PHP features when they are actually needed rather than providing you with abstract theory and contrived examples.In Learn PHP 8, programming examples take advantage of the newest PHP features; you’ll follow a learn-by-doing approach, which provides you with complete coding examples. “Do It” exercises in each chapter provide the opportunity to make adjustments to the example code. The end-of-chapter programming exercises allow you to develop your own applications using the algorithms demonstrated in the chapter.Each tier is logically and physically separated using object-oriented and dependency injection techniques, thus allowing independent tiers that can be updated with little or no effect on the other tiers. In addition to teaching good programming practices through OOP, there is a strong emphasis on creating secure code.As each chapter is completed, you’ll have the opportunity to design and create an application reinforcing the concepts learned.WHAT YOU WILL LEARN* Program PHP 8 web applications* Use interfaces, containers, and platforms* Apply modular programming * Manage data objects and use MySQL and other databasesWork with multi-functional and secure user interfaces * Handle logging exceptions and moreWHO THIS BOOK IS FORThose new to web development, specifically PHP programming.
