Aim/Purpose: This article examines how learning activities draw on resources in the work context to learn. Background The background is that if knowledge no longer is seen mainly as objects, but processes, how then to understand boundary objects? Our field study of learning activities reveals the use of pictures, documents and emotions for learning in the geographically distributed Norwegian Labor Inspection Authority Methodology: The study is a qualitative study consisting of interview data, observation data, and documents. Contribution: Contribute to practice based theorizing. Findings: Three ideal types of representing practices have been identified, i.e., ‘Visualizing’, ‘Documenting’ and ‘Testing’. All three are combined with storytelling, sensing, reflections and sensemaking, which point at the importance of processes in learning. The article also add insights about how emotions can be an important resource for boundary spanning – and sensemaking – by creating the capability of reflecting upon and integrating different knowledge areas in the in- practice context. Recommendations for Practitioners: Look for boundary objects within your field to promote online learning. Recommendation for Researchers: Study boundary objects in work context to understand learning. Impact on Society Role of objects in human learning. Future Research: Focus on how emotions can be used for online learning.

Large graphs or automata have their data that cannot fit in a single machine, or may take unreasonable time to be processed. We implement with MapReduce and Giraph two algorithms for intersecting and minimising large and distributed automata. We provide some comparative analysis, and the experiment results are depicted in figures. Our work experimentally validates our propositions as long as it shows that our choice, in comparison with MapReduce one, is not only more suitable for graph-oriented algorithms, but also speeds the executions up. This work is one of the first steps of a long-term goal that consists in a high level distributed graph processing language.

Course description:
Taxonomists need a common language worldwide. This is provided by the international codes of nomenclature. Although several codes exist, according to the organisms at stake, they all follow a similar mode of allocation of names to taxa (through "types") and of establishment of the valid name for a taxon (priority, first-reviser, usage). As biological nomenclature is rarely taught in academic formations, many taxonomists have difficulties mastering it. This training will provide an overview of the history and epistemology of biological nomenclature, and a discussion of the relationships between phylogeny, taxonomy and nomenclature. The zoological code will be presented in detail, the other codes (including the botanical one) more briefly. The recent problems and projects of nomenclature, including alternative systems, will be discussed.

Lecture topics:

• What is taxonomy? What is nomenclature? Name, taxon, nomenclatural rank, taxonomic category. Species and supraspecific taxa. The relationships between phylogeny, taxonomy and nomenclature
• History and epistemology of the international codes of nomenclature
• The international code of zoological nomenclature
• The other international codes (plants and fungi, bacteria, viruses, cultivated plants)
• The alternative nomenclatural systems

Seminar topics:

• Nomenclature of higher taxa in zoology
• The Phylocode and other phylogenetic nomenclatural systems
• Zoobank and electronic publications

Practical experiences will include: exercises in zoological nomenclature and transforming phylogenetic data into a taxonomy and a nomenclature.

Distributed European School of Taxonomy (DEST) is organizing a Botanical Nomenclature training course targeted at MSc students, PhD students, early career researchers,  professional systematists/taxonomists and anyone who is interested in the philosophy of Biological Systematics. The course has a duration of one week and will take place between 26-30 January 2015 at the Royal Botanic Gardens, Kew, UK.

Deadline for registrationis 10 October 2014. Participants will receive notification by 24 October 2014 whether accepted to the course. To register and to learn more about the course visit the official webpage: http://www.taxonomytraining.eu/content/botanical-nomenclature-3

Course description
This in-depth course will teach the principles of plant nomenclature according to the International Code of Nomenclature for algae, fungi and plants (ICN) so that participants can apply good nomenclatural practice when undertaking taxonomic revisions, compiling checklists etc. This will be achieved by lectures illustrated with examples from the ICN, workshop sessions applying what has been learned to "real life" cases, and by encouraging participants to discuss nomenclatural problems they have encountered.

Participants will have time to pursue their own research interests using the collections at Kew, with the emphasis on identifying and solving nomenclatural problems.
Short seminars will give participants the opportunity to present nomenclatural problems relevant to their own research.

Freelance 2024 facilitates enhanced connectivity, faster data transfer, more precise control and monitoring of data together with an improved network performance.

With the development of synchrotron radiation sources and high-frame-rate detectors, the amount of experimental data collected at synchrotron radiation beamlines has increased exponentially. As a result, data processing for synchrotron radiation experiments has entered the era of big data. It is becoming increasingly important for beamlines to have the capability to process large-scale data in parallel to keep up with the rapid growth of data. Currently, there is no set of data processing solutions based on the big data technology framework for beamlines. Apache Hadoop is a widely used distributed system architecture for solving the problem of massive data storage and computation. This paper presents a set of distributed data processing schemes for beamlines with experimental data using Hadoop. The Hadoop Distributed File System is utilized as the distributed file storage system, and Hadoop YARN serves as the resource scheduler for the distributed computing cluster. A distributed data processing pipeline that can carry out massively parallel computation is designed and developed using Hadoop Spark. The entire data processing platform adopts a distributed microservice architecture, which makes the system easy to expand, reduces module coupling and improves reliability.

The development of hard X-ray nanoprobe techniques has given rise to a number of experimental methods, like nano-XAS, nano-XRD, nano-XRF, ptychography and tomography. Each method has its own unique data processing algorithms. With the increase in data acquisition rate, the large amount of generated data is now a big challenge to these algorithms. In this work, an intuitive, user-friendly software system is introduced to integrate and manage these algorithms; by taking advantage of the loosely coupled, component-based design approach of the system, the data processing speed of the imaging algorithm is enhanced through optimization of the parallelism efficiency. This study provides meaningful solutions to tackle complexity challenges faced in synchrotron data processing.

New ETSI White Paper on Enhanced DNS Support in Distributed MEC Environments

Sophia Antipolis, 8 September 2020

Today ETSI announces the publication of its White Paper on DNS Support in Distributed MEC Environments. DNS (Domain Name System) is a key infrastructure element in any distributed edge cloud as it is used to ensure that modern (i.e. URL/URI-based) services requests are resolved to the properly located service instances. The best instance may often be decided based on properties other than location, e.g., service latency, resource availability as well as the device identifier.

ETSI publishes a white paper introducing Permissioned Distributed Ledger (PDL)

Sophia Antipolis, 24 January 2022

After the release of the first specification on smart contracts on 18 January, members from the ETSI PDL group published a White Paper entitled “An Introduction of Permissioned Distributed Ledger (PDL)”.

Distributed ledgers have consolidated as one of the most disruptive applications of information technology that have appeared in recent years. Their ability to store any kind of data as a consensus of replicated, shared, and synchronized digital records distributed across multiple sites, without depending on any central administrator, together with their properties regarding immutability (and therefore non-repudiation) and multi-party verifiability opens a wide range of applications.

In this Episode we talked about the new POSA 4 book which has recently been published. We talk to two of the authors, Kevlin Henney and Frank Buschmann (the third author, Doug Schmidt was not available - and he had also been on the podcast a couple of times :-)). The book contains a pattern language for distributed systems. It contains 114 patterns that had been published before by many different other authors. The patterns have been rewritten to form a consistent language. We basically talked through the different sections of the book, which gives a really good overview over the challenges and the solutions of building distributed systems. These sections include From Mud to Structure, Distribution Infrastructure, Event Demultiplexing and Dispatching, Interface Partitioning, Component Patitioning, Application Contrl, Concurrency, Synchronization, Object Interaction, Adaptazion and Extension, Modal Behaviour, Resource Management and finally, Database Access. The book references several other previous works (as listed below). Interestingly, many of these referenced works and authors have also been discussed previously on the podcast. Here are the back references:

• Domain Driven Design, Eric Evans
• Messaging Patterns, Gregor Hohpe
• POSA 2 Patterns, Doug Schmidt
• Concurrency: Part 1, Part 2, Part 3 and the interview with Goetz and Holmes
• Remoting Patterns Part 1 and Part 2
• POSA3, Resource Management
