The new CERN Single-Sign-On (SSO), built around an open source stack, has been in production for over a year and many CERN users are already familiar with its approach to authentication, either as a developer or as an end user. What is visible upon logging in, however, is only the tip of the iceberg. Behind the scenes there has been a significant amount of work taking place to migrate accounts management and to decouple Kerberos [1] authentication from legacy Microsoft components. Along the way the team has been engaging with the community through multiple fora, to make sure that a solution is provided that not only replaces functionality but also improves the user experience for all CERN members. This paper will summarise key evolutions and clarify what is to come in the future.

Software Defined Networking represents a mature technology for the control of optical networks, though all open controller implementations present in the literature still lack the adequate level of maturity and completeness to be considered for (pre)-production network deployments. This work aims at experimenting on, assessing and discussing the use of the OneM2M open-source platform in the context of optical networks. Network elements and devices are implemented as IoT devices, and the control application is built on top of an OneM2M-compliant server. The work concretely addresses the scalability and flexibility performances of the proposed solution, accounting for the expected growth of optical networks. The two experiment scenarios show promising results and confirm that the OneM2M platform can be adopted in such a context, paving the way to other researches and studies.

The paper ascribes to a belief that architecture should be wholly digital – from the scale of the micron and particle to the brick, beam and building, from design to fabrication or construction. This embodies a fundamental and disruptive shift in architecture and design thinking that is unique to the project images included, enabling design to become more inclusive, participatory and open-source. Architecture that is wholly digital requires a radical rethinking of existing design and building practices. Thes projects described in this paper each develops a set of parts in relationship to a specific digital fabrication technology. These parts are defined as open-ended, universal and versatile building blocks, with a digital logic of connectivity. Each physical part has a malefemale connection which is the equivalent of the 0 and 1 in digital data. The design possibilities – or the way that parts can combine and aggregate – can be defined by the geometry and therefore, design agency, of the piece itself. This discrete method advances a theoretical argument about the nature of digital design as needing to be fundamentally discrete, and at the same time responding to ideas coming from open-source, distributed modes methods of production. Furthermore it responds to today’s housing crisis, providing for a more democratic and equitable framework for the production of housing. To think of architecture as wholly digital is to substantially disrupt the way that we think about design, authorship, ownership and process, as well as the building technologies and practices we use in contemporary architectural production.

The Rohrbach Library of Kutztown University manages its electronic resources using a disconnected array of resources including spreadsheets, paper files, email files, and a Google Docs account. Clearly, a more streamlined and unified approach would be beneficial. In this case, the authors investigate various Electronic Resource Management System (ERMS) options and whether they are a fit for the library. They then examine the decision to implement an open source option. Finally, the case describes the process of implementing and populating the open source ERMS, in addition to challenges experienced along the way.

The maturity of free and open source movement has brought a number of ICT tools. It has affected the way courses are delivered, the way contents are developed, the way data are interoperable, the way learning and teaching materials are shared, the way learners access classes and the way library resources are shared. In developing countries, several libraries are migrating into digital libraries using low cost technologies readily available due to open access, free and open source technology and e-publishing tools. Recent development of cloud computing technology provides state of art tools for libraries. It provides a common platform for easy information storage and sharing. Thus, there is lowering of the cost required to procure and manage library ICT infrastructure due to the capability of that cloud computing which allows the storage to be on a single, efficient system that saves cost and time. In developing countries where most libraries suffer from limited budgets for ICT services, it is anticipated that the future of digital libraries is on cloud libraries.

There are many definitions of software Technical Debt (TD) that were proposed over time. While many techniques to measure TD emerged in recent times, there is still not a clear understanding about how different techniques compare when applied to software projects. The goal of this paper is to shed some light on this aspect, by comparing three techniques about TD identification that were proposed over time: (i) the Maintainability Index (MI), (ii) SIG TD models, and (iii) SQALE analysis. Considering 20 open source Python libraries, we compare the TD measurements time series in terms of trends and evolution according to different sets of releases (major, minor, and micro), to see if the perception of practitioners about TD evolution could be impacted. While all methods report generally growing trends of TD over time, there are different patterns. SQALE reports more periods of steady states compared to MI and SIG TD. MI is the method that reports more repayments of TD compared to the other methods. SIG TD and MI are the models that show more similarity in the way TD evolves, while SQALE and MI are less similar. The implications are that each method gives slightly a different perception about TD evolution.

A bridge is a structure providing passage over an obstacle without closing the way beneath. The required passage may be for a road, a railway, pedestrians, a canal or a pipeline. The obstacle to be crossed may be a river, a road, railway or a valley. In other words, bridge is a structure for carrying the road traffic or other moving loads over a depression or obstruction such as channel, road or railway. The structural analysis is carried out using BRIDGELINK software. Total 5 models are modeled in the Bridgelink software which is open source software. The moment, shear, rotation, deflection, reaction and stresses are computed for all the models.
