This set of slides introduces the reader to a subset of the C++ Standard Library called the Standard Template Library (STL). The STL provides a collection of parameterized containers and algorithms, and it is the most successful example of an approach to programming called generic programming. In this presentation, we aim at studying the ideals and concepts of the STL by re-implementing small parts of the library. Specifically, we first show how we can discover requirements on types in order to devise generic algorithms. Then, we focus on how to make algorithms independent of containers through the pivotal abstraction of iterators. To this end, we replicate the standard algorithm for finding the minimum in a sequence (min_element), which we subsequently match with a custom forward iterator over intrusive linked lists of integers. Finally, we see how function objects can be used to customize containers and algorithms alike. This allows us to deepen our understanding of ordering relations, and, in particular, to introduce the concept of strict weak orderings.
This set of slides introduces the reader to the concept of regular types, i.e., user-defined types whose semantics closely resembles that of built-in types. The notion of regular types proved crucial for the development of the C++ Standard Template Library, and it is currently employed in next-gen C++ libraries such as Eric Niebler's range-v3. The presentation serves as a gentle introduction to the topic, and discusses which requirements must be satisfied for a type to be regular. In particular, the concept of equality-preserving copy and assignment is presented, as well as how to define ordering relations that satisfy the requirements of strictness, transitivity and comparability (i.e., that adhere to the trichotomy law).
This set of slides introduces the reader to the concept of resource wrappers, i.e., classes that are responsible for the correct handling of resources of some kind (e.g., memory). In particular, the presentation discusses the design and implementation of a simplified version of std::vector for the specific case of integer elements. In this regard, we first discuss the fundamental role of destructors as a deterministic, general-purpose undo mechanism. Second, we notice that providing an explicit destructor entails the need of a consequent explicit implementation for the copy constructor and copy assignment operator. We conclude with the formulation of the so-called "rule of three".
This set of slides introduces the reader to the basics of memory management in C++ (with elements of C++11 and C++14). Specifically, after presenting the essential idea of memory segmentation, the presentation contrasts automatic and dynamic objects. To this extent the critical issue of memory leaks is introduced. It follows a discussion on the more advanced topics, such as owning and non-owning (i.e., observer) pointers, as well as dynamic arrays and structures.
This set of slides introduces the reader to the concept of operator overloading for user-defined types in C++ (with elements of C++11 and C++14). The exemplary case of the complex class is introduced. It follows a discussion on how to implement mixed-mode arithmetic, which requires mixing member and non-member operator functions. Moreover, the technical tool of friend functions and access functions is discussed.
This set of slides introduces the reader to the concept of multidimensional arrays in C++ (with elements of C++11 and C++14). The true nature of multidimensional arrays is discussed by means of an intermediate type alias. The pheonomenon of array-to-pointer decay and pointer arithmetic is then generalized to arrays of arrays. The presentation proceeds with a discussion on how to pass multidimensional arrays to functions.
This set of slides introduces the reader to the concept of arrays in C++ (with elements of C++11 and C++14). After presenting the array data type, the concept of array-to-pointer decay is introduced. The presentation proceeds with a discussion on how to pass arrays to functions. To this extent, the reader is guided to the use of bounded ranges as the first step towards the use of the Standard Template Library (STL).
An introduction to pointers and references in C++ (with elements of C++11 and C++14). The presentation introduces the readers to the concepts of pointers and references through the pragmatic need of writing a swap function between integers. Generic programming notions (e.g., type constructors) are adopted when useful for the explanation.
Spring MVC - Wiring the different layersIlio Catallo
The presentation focuses on the problem of wiring the different layers of a Spring MVC Web application. More precisely, the presentation explains how to wire the presentation layer (made of Spring MVC controllers) with the service and persistence objects. To this end, the slides first explain how to create the so called back-end (a.k.a. root) container, which will host the persistence and the service objects. Second, the @Repository and @Service annotations are introduced, which permit the framework to auto-discover the application beans. Finally, it is discussed how to wire such beans, through the usage of either the Spring-specific @Autowired annotation or the JEE @Inject annotation.
How to process request parameters with the Spring MVC framework. Namely, the presentation tackles the three primary concerns when dealing with request parameters: data binding, data buffering and data validation. To this end, the Bean Validation API (JSR-303) is discussed, and the concept of MessageSource for localized error messages is introduced. Moreover, The Post/Redirect/Get (PRG) pattern is presented along with a possible implementation strategy.
An introduction to the basics of the Spring MVC Web framework. The concepts of front controller, controller (handler), model and view are introduced. The whole processing pipeline is discussed, with an in-depth description of the HandlerMapping and ViewResolver strategy interfaces. The alternative representations of the Model (Map, Model and ModelMap) are presented.
This set of slides deals with the problem of building robust Web applications by isolating different areas of concern into different layers. The typical four-layer architecture is presented (consisting of the presentation, service and persistence layer, as well as of the domain model) along with an in-depth discussion on the role and responsibilities of each single layer.
Introduzione al concetto di oggetto nel modello della memoria del C++ e ai suoi possibile tempi di vita (temporaneo, automatico, dinamico, ...). Relazione tra il tempo di vita e la visibilità (scope) di un oggetto. Gestione degli oggetti dinamici per tipi primitivi, strutture e array mediante l'utilizzo di puntatori (raw pointers).
Introduzione agli Array in C++. Argomenti trattati: decadimento a puntatore di un array; conseguenze del meccanismo di decadimento sul passaggio di array a funzioni; array multidimensionali e il concetto di puntatore ad array; come passare array multidimensionali a funzioni; gli iteratori come generalizzazione di un puntatore ad elemento di un array ed una breve scorsa di come usare gli iteratori con gli algoritmi standard (e.g., std::copy) del C++.
Introduzione ai puntatori e ai riferimenti in C++. Viene presentato il problema dello swap, come esempio motivante per l'introduzione della semantica di riferimento. Si procede con l'introduzione del concetto di puntatore, a cui segue una spiegazione dei basilare operatori di referenziazione e dereferenziazione. Il problema dello swap viene risolto mediante puntatori. Si procede con l'introduzione dei riferimenti, come alias di variabili esistenti. Il problema dello swap viene in ultimo risolto mediante riferimenti.
An introduction to the Java Persistence API 2.x (JPA). Namely, this set of slides first introduces the problem of impedance mismatch between the object model and the relation model. Then, the EntityManager's public interface is discussed, together with the parallelism between a persistence context and a L1 cache. The issue of encapsulating the different application's use cases (which are exposed by the service objects) is solved by means of the @Transactional annotation, which provides a declarative way of demarcating the application's transactional boundaries. It follows an in-depth explanation on how to integrate a local, container-managed EntityManager within an existing Spring MVC application, so as to correctly support the propagation of the persistence context throughout the different beans involved in the same transaction. We then turn our attention to the problem of mapping relationships, thus introducing the @OneToMany, @ManyToMany and @OneToOne annotations. The additional topics of how to cascade operations and how to support lazy loading are covered as well. The presentation concludes with a discussion on how to use both the Criteria and Query API (and JPQL) to query the underlying database.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.
