Numerous attacks on Internet of Things (IoT) devices have shown that security cannot be neglected, even when building devices with just a few kB of memory. While it is common sense to run regular software updates and use state-of-the-art security on embedded or general purpose systems, this is often not possible with IoT devices. While many of those devices have the facilities to perform over-the-air updates, their memory and processing capabilities limit the use of state-of-the-art cryptography. Additionally, these devices often lack the capabilities to secure the cryptographic keys, the foundation on which the device's security is built, which makes them even more vulnerable to attacks. In this work, we present a pattern that allows even constrained devices to utilize state-of-the-art cryptographic functions, providing the foundation for a secure Internet of Things. The identified pattern presents the following characteristics: (i) confidentiality, by offloading the cryptographic functions and key storage; (ii) authenticity, by signing messages with the securely stored key using hash as well as signature functions, often too complex for such constrained devices on their own; (iii) integrity, a key requirement for connected sensors. As an added benefit, a faster detection of corrupted or tampered updates can also increase the availability of the system. This pattern is primarily targeted at IoT device vendors, who wish to keep their devices secure, by implementing security in hardware.

The Architectural Patterns for Parallel Programming is a collection of patterns related with a method for developing the coordination structure of parallel software systems. These architectural patterns take as input information (a) the available parallel hardware platform, (b) the parallel programming language of this platform, and (c) the analysis of the problem to solve, in terms of an algorithm and data. In this paper, it is presented the application of the architectural patterns along within the Coordination stage, as part of the Pattern-based Parallel Software Design Method, which aims for developing a coordination structure for solving the Laplace Equation. The Coordination stage here takes the information from the Problem Analysis presented in Section 2, selects an architectural pattern for the coordination in Section 3, and provides some elements about its implementationin Section 4.

Adult learners have specific features that differentiate them from children and the young. This specificity has been overlooked by an overwhelming part of the theoretical and applied research on education, which focuses on the early stages of life. Consequently, adult educators face a scarcity of reference models, guidelines and training materials supporting their daily practice. This paper aims at contributing to fill this gap, by providing advice and spurring methodological and practical discussion. We discuss concerns that have arisen from our experience both as adult educators and adult learners, and propose a set of patterns to tackle them. In particular, we present a self-reference model which has guided our performance as adult educators: the Democratic Learning catalyst. Commitment to Agreement sets up a framework for the adoption of such a model and its adaptation to specific contexts. Leveraging Experience exploits experience, an invaluable asset amassed by adults, putting it at the service of the collective learning process. Awareness of Progress accounts to the participants for the outcomes of the course. It is reassuring and encouraging, strengthens their self-confidence and generates a supportive climate. Lastly, adults' knowledge gets richer and their convictions become more soundly founded by means of Enlightening Discussion.

This paper introduces 'Wholeness Egg' as an effective technique for designing 'living' workshops. Christopher Alexander who explored the beauty of architecture emphasized that a creation is about making the design come to life as much as possible. He also put a significant emphasis on the wholeness and the fifteen fundamental properties which can be found in all living structures. Based on his design theory, we invented the Wholeness Egg as a methodology of designing living workshops by grasping the wholeness first and subsequently differentiating it into parts, in the way that it can achieve the properties. This paper presents how a living design is induced on a single egg-shaped diagram, by showing our Pattern-driven Dialogue Workshop as an example. It also shows that the application of this methodology helps people to externalize and open up the individuals' thinking processes and allows them to work collaboratively when designing things. We expect this paper to provide readers with a clear understanding of the Wholeness Egg with a view to using it effectively in their own practices of designing.

The Industry 4.0 initiative is pushing traditional production systems and methodologies through fundamental changes. In traditional industries such as manufacturing, utilities, and infrastructure monitoring, customers are demanding more flexibility and greater efficiency. The software that oversees these systems addresses these demands by adopting novel architectural styles and patterns. Industrial edge systems are gaining momentum because they offer superior data security and better response time to field operations. Microservice style has been adopted from cloud services because it improves development efficiency. This paper presents architecture patterns that cover four phases in the life cycle of industrial software. In the deployment phase, DOWNSHIFTING moves microservices from the cloud to the edge. During runtime, MONITORING CONNECTORS oversee properties of microservices at the edge, such as performance and resource usage. When adaptation is needed, EDGE-TO-CLOUD LOAD BALANCING leverages cloud resources to fulfill performance expectations. When a new microservice version is deployed, TEST PROBE enables testing the microservice at the edge without interfering with ongoing operations. This paper is intended for architects, developers and practitioners who are involved in delivering software in industrial edge environments.

The General Data Protection Regulation mandates data protection in the European Union. This includes data protection by design and having privacy-preserving defaults. This legislation has been in force since May 2018, promising severe consequences for violation. Fulfilling its mandate for data protection is not trivial, though. One approach for realizing this is the use of privacy design patterns. We have recently started consolidating such patterns into useful collections. In this paper we improve a subset of these, constructing a pattern system. This helps to identify contextually appropriate patterns. It better illustrates their application and relation to each other. The pattern system guides software developers, so that they can help users understand how their information system uses personal data. To achieve this, we rewrite our patterns to meet specific requirements. In particular, we add implementability and interconnection, while improving consistency and organization. This results in a system of patterns for informing users.

The Idioms for Synchronization Mechanisms is a collection of patterns related with the implementation of synchronization mechanisms for the communication components of parallel software systems. The selection of these idioms take as input information (a) the design pattern of the communication components to synchronize, (b) the memory organization of the parallel hardware platform, and (c) the type of communication required. In this paper, it is presented the application of the Idioms for Synchronization Mechanisms to synchronize the communication components for an N Body Simulation, within the Detailed Design stage of the Pattern-based Parallel Software Design Method. In two previous papers, this method has been used in two previous stages: (a) in the Coordination Design stage, selecting the Manager-Workers architectural patterns as the coordination, which depends on the N- Body problem; and (b) in the Communication Design stage, selecting the Remote Rendezvous design pattern as communication, which depends on the memory organization of the parallel hardware platform, and on the architectural pattern previously selected.

Numerous authorization models have been proposed for relational databases. On the other hand, several NoSQL databases used in Big Data applications use a new model appropriate to their requirements for structure, speed, and large amount of data. This model protects each individual cell in key-value databases by labeling them with authorization rights following a Role-Based Access Control model or similar. We present here a pattern to describe this model as it exists in several Big Data systems.

In this paper, it is presented the application of the Design Patterns for Communication Components to communicate components for a parallel implementation of the the Fast Fourier Transform, within the Communication Design stage of the Pattern-based Parallel Software Design Method.

In this paper, the design patterns Uncertain Number and Propagation Strategy are presented. They are useful for storing uncertainties of values and propagating them throughout calculations in an application. Uncertain Number represents a numerical value and its respective uncertainty. Propagation Strategy represents the propagation method, to correctly propagate the uncertainty throughout an application. This is done according to the Law of Propagation of Uncertainty as defined in the Guide to Expression of Uncertainty in Measurements. This paper addresses software architects, designers and developers having to work with uncertain data e.g. coming from sensors or other measurements.
