Das Medium aus der Maschine
»Die Informatik entwirft drei sehr unterschiedliche Bilder von Computer: Maschine – Werkzeug – Medium. Wie können so gegensätzliche Vorstellungen im gleichen Artefakt einen technologischen Ausdruck finden? Zu welchen Widersprüchen führen so differierende Sichtweisen in der Forschungspraxis der Informatik? Welches sind die Konzepte, über die sie sich verbinden lassen? Und wie verändert sich das Gewicht der Bilder von Maschine, Werkzeug und Medium in der Entwicklungsgeschichte des Computers und der Informatik?«Aus der EinleitungUnveränderter NachdruckHeidi Schelhowe, Prof. Dr., ist Professorin für Digitale Medien in der Bildung in der Informatik an der Universität Bremen und leitet dort die Arbeitsgruppe "Digitale Medien in der Bildung" (dimeb).

Practical Internet Server Configuration
Learn the skills to complete the full installation, configuration, and maintenance of an enterprise class internet server, no matter what Unix-like operating system you prefer. This book will rapidly guide you towards real system administration, with clear explanations along the way.After a chapter explaining the most important Unix basics, you will start with a vanilla server as delivered by a hosting provider and by the end of the book, you will have a fully functional and well-secured enterprise class internet server. You will also be equipped with the expertise needed to keep your server secured and up to date. All configuration examples are given for FreeBSD, Debian and CentOS, so you are free to choose your operating system.No single blueprint exists for an internet server, and an important part of the work of a system administrator consists of analyzing, interpreting and implementing specific wishes, demands and restrictions from different departments and viewpoints within an organization. Practical Internet Server Configuration provides the information you need to succeed as a sysadmin.WHAT YOU'LL LEARN* Configure DNS using Bind 9* Set up Apache and Nginx* Customize a mail server: IMAP (Dovecot) and SMTP (Postfix), spam filtering included* Authenticate mail users using LDAP* Install and maintain MariaDB and PostgreSQL databases* Prepare SSL/TLS certificates for the encryption of web, mail and LDAP traffic* Synchronize files, calendars and address books between devices* Build a firewall: PF for FreeBSD and nftables for LinuxWHO THIS BOOK IS FORThis book can be used by aspiring and beginning system administrators who are working on personal servers, or more experienced system administrators who may know Unix well but need a reference book for the more specialized work that falls outside the daily routine. Basic understanding of Unix and working on the command line is necessary.Robert La Lau has been active on the internet since the mid-90s. What started as a hobby – playing around with Linux, and developing small games and applications using Perl, HTML and JavaScript – turned into a job when he became a full-time freelance web developer in 1999. Shortly thereafter, a web hosting server and freelance Linux and FreeBSD administration were added. In the years that followed, new programming languages were learned, and software development was added to the range of services offered. In his spare time, Rob was involved in several smaller and larger open source projects; among other things, he was the initiator and first administrator for the official online KDE forums. After 15 years of freelance IT work, Rob thought he'd had enough of IT work, finished his running affairs, and left the Netherlands to discover the world. However, the IT kept calling him, and once installed in his new home country France, he decided to return to his old métier. Only this time, it was not to get his own hands dirty in the field, executing orders for clients, but to transfer his knowledge and experience onto the next generations of system administrators and developers. He rebooted his IT career translating and narrating educational books and videos, taught some Unix classes, and seems to have found his destination publishing books now.1.

Stochastic Approaches to Electron Transport in Micro- and Nanostructures
The book serves as a synergistic link between the development of mathematical models and the emergence of stochastic (Monte Carlo) methods applied for the simulation of current transport in electronic devices. Regarding the models, the historical evolution path, beginning from the classical charge carrier transport models for microelectronics to current quantum-based nanoelectronics, is explicatively followed. Accordingly, the solution methods are elucidated from the early phenomenological single particle algorithms applicable for stationary homogeneous physical conditions up to the complex algorithms required for quantum transport, based on particle generation and annihilation. The book fills the gap between monographs focusing on the development of the theory and the physical aspects of models, their application, and their solution methods and monographs dealing with the purely theoretical approaches for finding stochastic solutions of Fredholm integral equations.

Many, if not most, ABAP programmers learned their programming and testing skills before the ABAP development environment provided an automated unit testing facility.AUTOMATED UNIT TESTING WITH ABAP: A PRACTICAL APPROACH offers hope and salvation to ABAP programmers who continue to toil with antiquated manual unit testing processes, taking them by the hand and lifting them out of that dungeon of despair with a modern and proven alternative. It begins by explaining how the xUnit family of automated testing frameworks provides a quick and effective means of insuring high-quality software. It then focuses on the ABAP Unit Testing Facility, the xUnit framework applicable specifically to the ABAP language, showing how it can be used to bring ABAP applications underautomated testing control, from old legacy applications to those newly written.Whereas xUnit testing has been widely accepted with developers writing in many other programming languages, it is an unfortunate fact in the ABAP community that many programmers still are unfamiliar with xUnit concepts and do not know how to begin implementing automated unit testing into their development process. This book demonstrates how to refactor programs so they become designed for testability, showing how to use process encapsulation and test isolation to facilitate automated testing, including a thorough explanation of test-driven development and the use of test doubles. The book:* Shows how to write automated unit tests for ABAP* Instills ABAP programmers with the confidence to refactor poorly written code* Explains how an automated testing harness facilitates rapid software development* Teaches how to utilize test-driven development (TDD) withABAP* Offers advice and tips on the best ways to write automated unit testsWHAT YOU WILL LEARN* Become familiar with the xUnit approach to testing* Know the ABAP statements that interfere with running automated unit tests and how to accommodate them* Understand what it means to isolate code for testing and how this is achieved* Gain the confidence to refactor poorly written code* Make ABAP programs designed for testability* Reap the benefits of spending less time manually unit testing ABAP programs* Use test-driven development (TDD) with ABAP programming* Use configurable test doubles in ABAPWHO THIS BOOK IS FORABAP programmers who remain unfamiliar with the automated unit testing facility and those who already use it butwant to improve their skill writing and using automated tests. The book addresses the reluctance and trepidation felt by procedural ABAP programmers who need to know some object-oriented concepts to use this facility, expands their horizons, and helps them step through the doorway leading to a different approach to program design. JAMES E. MCDONOUGH received a degree in music education from Trenton State College. After teaching music for only two years in the New Jersey public school system, he spent the past 38 years as a computer programmer while also maintaining an active presence as a freelance jazz bassist between New York and Philadelphia. Having switched from mainframe programming to ABAP in 1997, he now works as a contract ABAP programmer designing and writing ABAP programs on a daily basis. An advocate of using the object-oriented programming features available with ABAP, he has been teaching private ABAP education courses over the past few years, where his background in education enables him to present and explain complicated concepts in a way that makes sense to beginners.Chapter 1: Introduction.- Chapter 2: Preparing to Take the First Step.- Chapter 3: Software Quality.- Chapter 4: The Origins of Automated Unit Testing.- Chapter 5: Automated Unit Testing with ABAP.- Chapter 6: Rudiments.- Chapter 7: Design for Testability.- Chapter 8: Test Doubles.- Chapter 9: Service Locator.- Chapter 10: Leveraging the Service Locator.- Chapter 11: Test-Driven Development.- Chapter 12: Configurable Test Doubles.- Chapter 13: Obtaining Code Coverage Information Through ABAP Unit Testing.- Chapter 14: Cultivating Good Test Writing Skills.- Chapter 15: Welcome to Autropolis.- Appendix A: Requirements Documentation and ABAP Exercise Programs.- Appendix B: Answers to Chapter Quizzes.- Appendix C: Concepts Associated with Defining Local Test Classes.-
