Worked examples (solutions to typical programming problems presented as a source code in a certain language and are used to explain the topics from a programming class) are among the most popular types of learning content in programming classes. Most approaches and tools for presenting these examples to students are based on line-by-line explanations of the example code. However, instructors rarely have time to provide line-by-line explanations for a large number of examples typically used in a programming class. In this paper, we explore and assess a human-AI collaboration approach to authoring worked examples for java programming. We introduce an authoring system for creating java worked examples that generates a starting version of code explanations and presents it to the instructor to edit if necessary. We also present a study that assesses the quality of explanations created with this approach. © 2023, CC BY-NC-ND.

The popularity of the java programming language has led to its wide adoption in cloud computing infrastructures. However, java applications running in untrusted clouds are vulnerable to various forms of privileged attacks. The emergence of trusted execution environments (TEEs) such as Intel SGX mitigates this problem. TEEs protect code and data in secure enclaves inaccessible to untrusted software, including the kernel and hypervisors. To efficiently use TEEs, developers must manually partition their applications into trusted and untrusted parts, in order to reduce the size of the trusted computing base (TCB) and minimise the risks of security vulnerabilities. However, partitioning applications poses two important challenges: (i) ensuring efficient object communication between the partitioned components, and (ii) ensuring the consistency of garbage collection between the parts, especially with memory-managed languages such as java. We present Montsalvat, a tool which provides a practical and intuitive annotation-based partitioning approach for java applications destined for secure enclaves. Montsalvat provides an RMI-like mechanism to ensure inter-object communication, as well as consistent garbage collection across the partitioned components. We implement Montsalvat with GraalVM native-image, a tool for compiling java applications ahead-of-time into standalone native executables that do not require a JVM at runtime. Our extensive evaluation with micro- and macro-benchmarks shows our partitioning approach to boost performance in real-world applications up to 6.6× (PalDB) and 2.2× (GraphChi) as compared to solutions that naively include the entire applications in the enclave. © 2023, CC BY.

Despite its already widespread popularity, it continues to gain adoption. More and more developers and architects continue to adopt and apply the FaaS (Function as a Service) model in cloud solutions. The most extensively used FaaS service is AWS Lambda, provided by Amazon Web Services. Moreover, despite the new trends in programming languages, java still maintains a significant share of usage. The main problem that arises when using these two technologies together is widely known: significant latencies and the dreaded cold start. However, it is possible to greatly mitigate this problem without dedicating too much effort. In this article, various techniques, strategies and approaches will be studied with the aim of reducing the cold start and significantly improving the performance of Lambda functions with java. Starting from a system that involves AWS lambda, java, DynamoDB and Api Gateway. Each approach will be tested independently, analyzing its impact through load tests. Subsequently, they will be tested in combination in an effort to achieve the greatest possible performance improvement. © 2023, CC BY.

In this study, we assess the efficacy of employing the ChatGPT language model to generate solutions for coding exercises within an undergraduate java programming course. ChatGPT, a large-scale, deep learning-driven natural language processing model, is capable of producing programming code based on textual input. Our evaluation involves analyzing ChatGPT-generated solutions for 80 diverse programming exercises and comparing them to the correct solutions. Our findings indicate that ChatGPT accurately generates java programming solutions, which are characterized by high readability and well-structured organization. Additionally, the model can produce alternative, memory-efficient solutions. However, as a natural language processing model, ChatGPT struggles with coding exercises containing non-textual descriptions or class files, leading to invalid solutions. In conclusion, ChatGPT holds potential as a valuable tool for students seeking to overcome programming challenges and explore alternative approaches to solving coding problems. By understanding its limitations, educators can design coding exercises that minimize the potential for misuse as a cheating aid while maintaining their validity as assessment tools. © 2023, CC BY-NC-ND.

The article describes the Web Application Lego Toolkit (WALT), which is a template-oriented platform designed for the development of web applications of various degrees of complexity. Unlike some other platforms, which represent a "magic black box", the main idea of WALT is to provide transparent, extensible, and modifiable tools for solving some specific problems that arise when developing web applications. WALT is primarily intended for use by individual full-stack developers or small groups of developers. The article depicts the WALT architecture and provides examples of its use for the development of JINR corporate web applications. © 2021 CEUR-WS. All rights reserved.

Mobile health (MH) technologies and electronic medical record represent a powerful solution which can help both patients and doctors in daily health monitoring and treatment, especially for patient's leaves in rural areas. In this context, we propose to design and build a mobile application for the management of a patient's medical data on the Cloud. In this paper, we define the medical record in a comprehensive manner and then present the mobile applications as well as the mobile operating system used, the Android system. The proposed work is composed of two parts;firstly, we choose UML formalism to model our application. Our choice was based on its simplicity, performance and design readiness. Secondly, in order to achieve this mobile application, we used the java programming language under the Android Studio development environment, and when implementing our application's data storage space, we used XML for data structure and Cloud Computing as a storage space for its security and to protect the patient's privacy. © 2021 IEEE.

Two code fragments that are identical to each other and repeatedly being implemented in a software program are called code clones. Code clones are classified into four different type which are clone Type-1, clone Type-2, clone Type-3 and clone Type-4. In the past decades, variegated code clone approaches as well as tools have been utilized for detecting code clones. However, the minimum comprehensiveness or lacking of generality in detecting all four types of code clone, has prompted other researchers to develop a code clone detection model. Generic Code Clone Detection (GCCD) Model is the model that implemented a clone detection for the four types of code clone. GCCD incorporates with process namely Pre-processing, Transformation, Parameterization, Categorization and Match Detection process. This research study intends to ameliorate the code clone detection of GCCD Model through Match Detection process of the respective model. A literature review is done to center a few other models and techniques and distance measure formula that available for calculating the code clones in Match Detection process. Based on the analysis, there are ten distance measure formula will be used to decide on the best method for calculating the code clone in Match Detection process. This study hopes to be used as reference for other researchers in aiding their research regarding code clone detection model. © 2021 IEEE.
