The presence now of the Web in every area of life demands studies which constitute it simultaneously both as itself a contextualising object and as anchored in a context. Contextualising because today it directly influences an infinite number of objects, which can no longer be studied without taking account of their echoes online. In transmedia dynamics in particular, we can see how the Web is increasingly becoming an ever-present backdrop to controversies, to the configuration of information and even to interpersonal relationships. Equally, the Web must find its own contextualisation, first of all – since we are historians – from a diachronic perspective. The first challenge is not to remain within the limits set by the technology itself. This twofold approach (the Web in context and the Web as context) suggests how focused we need to be on the construction of an ever-changing socio-technical reality – a return to a totalising, process-focused history which takes account of ongoing developments. We should resist the effects of any discourse tending to fix realities or establish, in hieratic or metonymic fashion, an image of ‘THE’ Web. The present analysis falls into three main sections, which interrogate, in turn, the diachronic or temporal contextualisation, the boundaries or spatial contextualisation, and finally collective and individual experiences of the Web.

Cet ouvrage s’inscrit dans le cadre d’une histoire jeune et très contemporaine, celle d’Internet, du Web et des cultures numériques et explore leur fabrique dans les années 1990 en France. Cette recherche, à la croisée de l’histoire des médias, de l’histoire de l’innovation, et de l’histoire sociale et culturelle, reflète les apports d’une approche française de l’histoire d’Internet et du Web. Matérialité et infrastructures, temporalités et trajectoires, espaces et territoires traversent les cinq chapitres du livre. Ils apportent des arguments au choix d’une analyse nationale d’un phénomène pourtant transnational, en s’intéressant à l’attribution des noms de domaine et à la francophonie au sein de la Toile, à la transition entre la culture Minitel et celle du Web, ou encore à la place d’un État qui passe du volontarisme et du monopole des télécommunications à la dérégulation et aux imaginaires des autoroutes puis de la société de l’information. Explorant les pratiques, difficultés, tâtonnements de la période et le tournant grand public du Web, on croise au cours de cette navigation des informaticiens, des entrepreneurs, des politiques, des passionnés de science-fiction, des militants, autant d’acteurs qui se confrontent, débattent, co-construisent. Ils vous invitent à les suivre dans un chantier entre « cathédrale et bazar », pour reprendre Eric Raymond, dont l’exotisme mais aussi l’actualité des débats ne cessent de nous frapper. Bienvenue dans le Cyberespace des années 1990 ! [less ▲]

This chapter seeks to show the value of a relational, practice-oriented approach – what in STS vocabulary is called ‘unpacking black boxes’, or doing a sociology ‘of assemblages’. The chapter examines how this approach can shed light on the hybrid mobilizations of innovators, consumers, users and entrepreneurs – alongside their creations and cultures – that have made the Web the complex socio-technical system it is today.

The transformation of the European Union’s energy sector poses a number of challenges to the European electricity system. Above all, both the anticipated increase of intermittent electricity from renewable sources and the completion of the internal energy market while guaranteeing a secure supply require an extensive development of electricity infrastructure at the European level. Nevertheless, Europe’s future electricity system entails numerous uncertainties. For example, the definite amount and the location of both electricity generation and consumption are unpredictable. In order to address these ambiguities, the European Network of Transmission System Operators for Electricity (ENTSO-E) develops the two-yearly Ten-Year Network Development Plan (TYNDP). By exploring different plausible future paths using scenarios, the TYNDP aims to identify key infrastructure projects – namely transmission lines and cross-border interconnectors – for the future electricity system. In this capacity, the TYNDP is the central planning tool for European grid infrastructure. This paper explores whether the TYNDP effectively provides a solid planning foundation for future grid investments. For this end, the TYNDPs 2012-2018 are investigated in the light of European energy policies, and their utilization by stakeholders is scrutinized. The paper argues that an existing policy congruence and the strong link to the Projects of Common Interest (PCI) confine the TYNDP solely to the hardware of the electricity system. This in turn profoundly limits the TYNDP’s effectiveness as a strategic planning tool. Hence, a closer connection to the software components of the anticipated European electricity system – namely the future market design and (European) regulations – would further allow for a holistic planning and evaluation of future electricity infrastructure projects.

Context: Evolutionary algorithms have been shown to be e ective at generating unit test suites optimised for code coverage. While many speci c aspects of these algorithms have been evaluated in detail (e.g., test length and di erent kinds of techniques aimed at improving performance, like seeding), the in uence of the choice of evolutionary algorithm has to date seen less attention in the literature. Objective: Since it is theoretically impossible to design an algorithm that is the best on all possible problems, a common approach in software engineering problems is to rst try the most common algorithm, a Genetic Algorithm, and only afterwards try to re ne it or compare it with other algorithms to see if any of them is more suited for the addressed problem. The objective of this paper is to perform this analysis, in order to shed light on the in uence of the search algorithm applied for unit test generation. Method: We empirically evaluate thirteen di erent evolutionary algorithms and two random approaches on a selection of non-trivial open source classes. All algorithms are implemented in the EvoSuite test generation tool, which includes recent optimisations such as the use of an archive during the search and optimisation for multiple coverage criteria. Results: Our study shows that the use of a test archive makes evolutionary algorithms clearly better than random testing, and it con rms that the DynaMOSA many-objective search algorithm is the most e ective algorithm for unit test generation. Conclusions: Our results show that the choice of algorithm can have a substantial in uence on the performance of whole test suite optimisation. Although we can make a recommendation on which algorithm to use in practice, no algorithm is clearly superior in all cases, suggesting future work on improved search algorithms for unit test generation [less ▲]

Although the ARPANET was a United States-funded project that was deeply rooted in US post-war science and technology policies, it had an international dimension from its very early days. The memories of Michel Elie and Gerard Le Lann are oriented towards their US experience. They testify to an early French presence in the ARPANET project at two stages of its history: in 1969–1970, when the first nodes came into activity, and in 1973–1974, when TCP, which evolved into TCP/IP and became the Internet’s flagship protocol, was defined, replacing NCP, which was at the heart of the ARPANET. They thus highlight crucial but different sides of the ARPANET’s genesis. [less ▲]

We introduce a set of four twisted Edwards curves that satisfy common security requirements and allow for fast implementations of scalar multiplication on 8, 16, and 32-bit processors. Our curves are defined by an equation of the form -x^2 + y^2 = 1 + dx^2y^2 over a prime field Fp, where d is a small non-square modulo p. The underlying prime fields are based on "pseudo-Mersenne" primes given by p = 2^k - c and have in common that p is congruent to 5 modulo 8, k is a multiple of 32 minus 1, and c is at most eight bits long. Due to these common features, our primes facilitate a parameterized implementation of the low-level arithmetic so that one and the same arithmetic function is able to process operands of different length. Each of the twisted Edwards curves we introduce in this paper is birationally equivalent to a Montgomery curve of the form -(A+2)y^2 = x^3 + Ax^2 + x where 4/(A+2) is small. Even though this contrasts with the usual practice of choosing A such that (A+2)/4 is small, we show that the Montgomery form of our curves allows for an equally efficient implementation of point doubling as Curve25519. The four curves we put forward roughly match the common security levels of 80, 96, 112 and 128 bits. In addition, their Weierstraß representations are isomorphic to curves of the form y^2 = x^3 - 3x + b so as to facilitate inter-operability with TinyECC and other legacy software. [less ▲]

Dieses Kapitel stellt die Befunde aus drei Datenerhebungen (2014, 2015, 2016) der ÉpStan im Zyklus 2.1 vor und zeigt welche schulischen Kompetenzen Erstklässler am Anfang ihrer Schullaufbahn aufweisen und wie sich diese über zwei Jahre hinweg entwickeln. Allgemein betrachtet, sind die für den Zyklus 1 festgehaltenen Bildungsstandards in den drei überprüften Kernkompetenzen („Luxemburgisch-Hörverstehen“, „Vorläuferfertigkeiten der Schriftsprache“ und „Mathematik“) erfüllt. In allen drei Kompetenzen erreicht die Mehrheit der Schülerinnen und Schüler zu Beginn des Zyklus 2.1 das Niveau Avancé. Zwei Jahre später, im Zyklus 3.1, fällt die Verteilung der Schülerinnen und Schüler auf die verschiedenen Kompetenzränge negativer aus als im Zyklus 2.1. Hier haben vergleichsweise mehr Kinder das Niveau Socle in allen drei Kernkompetenzen noch nicht erreicht. Unsere Befunde zeigen außerdem, dass verschiedene außerschulische Faktoren (wie z. B. sozioökonomische Situation, Sprachhintergrund) bereits sehr früh im Verlauf der Schullaufbahn einen äußerst starken Einfluss auf die Testergebnisse haben und dass sich dieser Einfluss über die Jahre hinweg verstärkt.
