The materials detail code smells, indicators of underlying problems in code categorized as bloaters, object-orientation abusers, change preventers, dispensables, and couplers, and provide numerous examples of each. Furthermore, the resources present various refactoring techniques, categorized by composing methods, moving features, organising data, simplifying conditionals, simplifying method calls, and dealing with generalisation, illustrating their application with before-and-after code examples. Finally, the sources discuss when and how to refactor effectively, including...2025-04-2520 minRevision4) Design Patterns - CS2800 - Software EngineeringThese materials from lecture slides cover design patterns, which are reusable solutions to common software design challenges. The initial set of slides introduces the motivation and classification of these patterns, categorising them as creational, behavioral, and structural. Specific patterns like Singleton and Factory (both abstract and regular) within the creational category are detailed, alongside behavioral patterns such as Observer and State. The subsequent slides continue by examining structural patterns like Facade and Bridge, which focus on object composition, and conclude with an overview of the Model-View-Controller (MVC) architectural pattern, emphasising its role in separating concerns within an application.2025-04-2521 minRevision3) UML - CS2800 - Software EngineeringThis material introduces Unified Modelling Language (UML) as a graphical tool for software system design and communication, highlighting the class diagram as a frequently used type for outlining classes and their relationships. It then transitions to software design principles, including SOLID, emphasizing concepts like separation of concerns and avoiding repetition, while noting these are guidelines rather than strict rules. Finally, the text introduces the Spring Framework, an enterprise Java platform, covering its core features like Dependency Injection and Data Access Objects, and explains how to handle web requests and perform testing using Spring Boot and MockMvc.2025-04-2515 min
Revision2) Maintainable Code - CS2800 - Software EngineeringThese sources present essential practices for developing maintainable software, particularly within a Java environment. They introduce key tools and libraries such as Maven for build automation, JUnit for unit testing, and static analysis tools like Checkstyle and SpotBugs for code quality. The materials emphasise the importance of writing well-documented code using Javadoc and following established coding standards to ensure consistency. Furthermore, they outline the principles of Test-Driven Development (TDD) and the benefits of Continuous Integration (CI) and Continuous Deployment (CD) pipelines for automated validation and deployment. Finally, the sources cover collaborative aspects of software development, including issue tracking and...2025-04-2537 minRevision1) Version Control - CS2800 - Software EngineeringThis material introduces the Version Control System (VCS), explaining its purpose in tracking file changes and enabling team collaboration on code, configurations, and documentation. It distinguishes between centralised (like SVN) and distributed (like Git and Mercurial) VCS, highlighting the advantages of the latter in terms of scalability and flexibility. The resource focuses extensively on Git, detailing its snapshot-based approach, local operations, file lifecycle, and the significance of commits, branching, and merging, including how to handle conflicts. Finally, it touches upon remote repositories, the role of platforms like GitLab for hosting and collaboration, and recommends resources for further learning about...2025-04-2519 min
Revision5) Network & Control - IY2760 - Informational SecurityThese materials from Dr Ng's Information Security course at RHUL cover fundamental concepts of computer and network security, with a significant focus on access control mechanisms and models like ACLs, capability lists, RBAC, and matrix-based approaches. The texts also explore network security protocols such as IPsec and TLS, alongside methods for intrusion prevention and detection, including firewalls and IDSs. Furthermore, emerging topics like quantum computing and its cryptographic implications, alongside software vulnerabilities and malicious software, are introduced to provide a broader understanding of contemporary security challenges.2025-04-2529 min
