Programmeringsteknikker

Denne bog giver en introduktion til programmeringssproget Struktureret Tekst (ST) der benyttes i Programmerbare Logiske Controllere (PLC) Indhold: - Baggrund, fordele og udfordringer ved ST-programmering - Syntaks og grundlæggende ST-programmering - Stor guide til fornuftig navngivning af variabler - CTU, TOF, TON, CASE, STRUCT, ARRAY, STRING - Guide til opdeling i program moduler og funktioner - Mere end 90 PLC-kode eksempler i farver - FIFO, RND, 3D ARRAY, digitalt filter - Eksempler: Kom fra LADDER over til ST-programmering - Guide til løsning af programmeringsopgaver Bogen går systematisk frem med beskrivelse af de grundlæggende ST-begreber og programmering, herunder tips, og med inddragelse af forfatterens 25 års praktiske erfaring. Der er mange steder uddybende forklaringer til PLC-koden og der er fokus på at læseren lærer at skrive robust, læsbar, struktureret og overskuelig PLC-kode. Desuden fokuseres på at kunne skrive PLC-kode, som ikke kræver en bestemt PLC-type og PLC-kode der kan genbruges, samt PLC-løsninger, der kan benyttes internationalt. Grundlaget for bogen er et materiale, som er udarbejdet løbende med feedback fra undervisere og studerende på automationsteknolog-uddannelsen hos Erhvervs-akademi Dania. Materialet er således løbende opdateret, så det giver svar på de spørgsmål og udfordringer, de studerende typisk har gennem deres studie. ST-programmering til PLC-styringer er fra omkring år 2010 begyndt at blive mere udbredt i Danmark, og siden år 2015 er mange virksomheder i Danmark begyndt udelukkende at levere PLC-styringer, hvor der benyttes ST som det foretrukne programmeringssprog. Dette kræver at flere medarbejdere kan ST og det er et af argumenterne, for at udgive denne bog. Bogen er primært udarbejdet til brug på den videregående fuldtidsuddannelse Automationsteknolog og deltidsuddannelsen Automation og Drift.

Modellierung ist die Vorstufe zur Softwareentwicklung. Modelle werden vor allem in den frühen Phasen des Entwicklungsprozesses, aber auch in späteren erstellt. Aus den Modellen wird die Gesamtstruktur eines Informationssystems (IS) abgeleitet. Das Buch stellt die verschiedenen Modellarten im Zusammenhang vor und zeigt an zahlreichen Beispielen, wie man praktisch modelliert. Behandelt werden Modelle von Geschäftsprozessen, Daten, Funktionen und darüber hinaus von Organisationen, IT-Infrastrukturen und IS-Landschaften. Für jeden Bereich gibt es unterschiedliche Modellierungsansätze, z.B. Business Process Model and Notation (BPMN) und Ereignisgesteuerte Prozessketten für Geschäftsprozesse, Entity-Relationship-Modelle für Daten und Funktionshierarchiediagramme für Funktionen. Außerdem stellt die Unified Modeling Language (UML) eine breite Palette von Modelltypen zur Verfügung. In dem Buch werden für die betriebliche Praxis wichtigsten Modelle und Diagramme erläutert und die Querbeziehungen aufgezeigt. Da man Diagramme i.d.R. mit Hilfe von Softwarewerkzeugen erzeugt, werden auch typische Modellierungswerkzeuge behandelt. Das Buch richtet sich an Einsteiger, sowohl an Studierende (z.B. Wirtschaftsinformatik, Informatik, Betriebswirtschaftslehre) als auch Praktiker/innen, die in Bereichen wie Requirements Engineering, Systemanalyse oder Anwendungsentwicklung tätig werden wollen.

Invasive computing is a paradigm for designing and programmingfuture parallel computing systems. For systems with 1,000 or more cores on a chip, resource-aware programming is of utmost importance to obtain high utilisation as well as computational, energy and power efficiency. Invasive computing provides a programmer explicit handles to specify and argue about resource requirements desired or required in different phases of execution: In an invade phase, an application asks the operating system to allocate a set of processor, memory and communication resources to be claimed. In a subsequent infect phase, the parallel workload is spread and executed on the obtained claim of resources. Finally, if the degree of parallelism should be lower again, a retreat operation frees the claim again, and the application resumes a sequential execution. To support this idea of self-adaptive and resource-aware programming, not only new programming concepts, languages, compilers, and operating systems were needed to be developed, but also revolutionary architectural changes in the design of MPSoCs (multiprocessor systems-on-a-chip) to efficiently support invasion, infection, and retreat operations. This book gives a comprehensive overview of all aspects of invasive computing.

Hello! How are you and how is your Continuous Improvement journey going on? Are there any new skills that you want to acquire this year? My earlier books were on the following topics: DevOps, Microservices, and Kubernetes & Site Reliability Engineering. In the last four months, I have been heavily involved in the recruitment process of various DevOps related jobs in my current project. I have come across multiple Entry Level and Mid-Level career professionals inquisitive about expectations of the role and how their earlier experience would contribute to the DevOps role. Also, I have received several emails from readers asking how to switch from their existing roles (development, sys admin, etc.). Based on the interactions, I have included "DevOps Engineer" related queries in the below categories and in this book, I will give you complete information about the position, career path and skill set required.The main queries were the following: Why DevOps?What are the job duties and day-to-day activities of a DevOps Engineer?What did DevOps engineers do before DevOps?What technical and soft skills are required to be an expert-level DevOps Engineer?What are some standard tools a DevOps engineer uses?What are other similar roles from where one can make the transition to the DevOps world?What are the Certifications/Courses one can do to become a DevOps Engineer?How can I get DevOps interviews with top companies?What are the average Salary, companies to work for, and designations/roles?How is the career path of a "DevOps Engineer"? How is the career advancement of a DevOps engineer?The book covers most of this information. Over the course of the book, you will gather information on what DevOps is, and how you can use it to improve your processes. You will also identify the different roles that are linked to DevOps. If you are keen on becoming a DevOps engineer, the last few chapters include information on what skills you need to develop and what path you need to choose. Also, the last chapter contains sample interview questions, which are the most common ones asked during a DevOps interview.Overall, this book is aimed at professionals looking for DevOps role overview in limited timeframe. If you have to connect the dots regarding your existing experience, credentials and its fitment/relationship with the DevOps role, it would provide you much needed clarity. It also talks about other similar and related roles and its relationship with DevOps role. Also, if you are part of Project Management Team or Business Development Team or recruitment team (HR) this book will provide you required information about the DevOps role.The Continuous Delivery is here to stay and evolve. The nomenclature would change; new buzzwords would come and go. So, if you are into this space, adapt to it and make it your growth engine.Cheers!
