Il y a 30 ans Le Web naissait au CERN / Fluckiger, Francois
À l'occasion du 30e anniversaire de l'invention du Web, l'auteur, qui a succédé en 1974 à Tim Berners Lee quand celui-ci a quitté le CERN pour le MIT, explique les origines du Web, le contexte de l’Internet à l’époque de son invention, et corrige certaine idées reçues sur le genèse de cet immense avancée..

Le Web a été un accélérateur de l'irrationalité / Fluckiger, Francois
À l'occasion du 30e anniversaire de l'invention du Web, l'auteur, qui a succédé en 1974 à Tim Berners Lee quand celui-ci a quitté le CERN pour le MIT, reviens sur les origines de cette immense avancée, et explore ses conséquences sociétales : la prédominance croissante des systèmes de croyances sur les systèmes de connaissances c'est-à-dire sur La Science, et la montée de l'irrationalité.

The European Researchers’ Network / Fluckiger, Francois
In spite of what has often been said, the Internet is not a positive product of unconstrained liberalism, nor a product of the imagination of private enterprise which is free of the straightjacket of autocratic policy; neither could have accomplished something that both Governments and major institutions had failed to achieve..

Le réseau des chercheurs européens / Fluckiger, Francois
Contrairement à ce qui a souvent été dit, l'Internet n'est pas le produit positif du libéralisme débridé, de l'esprit d'entreprise privée qui, libéré du carcan des programmes étatiques, aurait réalisé ce que ni les gouvernements ni les grandes institutions n'avaient réussi. Non, la mise en place d'un réseau d'information mondial, fondé sur des normes universelles, est bel et bien le fruit de la recherche publique : Internet est le produit indirect des universités et laboratoires qui non seulement ont inventé la technologie, mais - fait plus rare - l'ont déployée en un réseau mondial opérationnel, au service des chercheurs..

Increasing Windows security by hardening PC configurations / Martin Zamora, Pablo (CERN) ; Kwiatek, Michal (CERN) ; Bippus, Vincent Nicolas (CERN) ; Cruz Elejalde, Eneko (Oviedo U.)
Over 8000 Windows PCs are actively used on the CERN site for tasks ranging from controlling the accelerator facilities to processing invoices. PCs are managed through CERN's Computer Management Framework and Group Policies, with configurations deployed based on machine sets and a lot of autonomy left to the end-users. [...]

Trident : An automated system tool for collecting and analyzing performance counters / Muralidharan, Servesh (CERN) ; Smith, David (CERN)
Trident, a qualitative analysis tool that can look at various low level metrics with respect to the Core, Memory and I/O to highlight performance bottlenecks during the execution of an application. Trident uses a three pronged approach in analyzing a node's utilization of hardware resources and to help a non system expert understand the stress on different parts of the system by a given job.

Identifying Devices of the Internet of Things Using Machine Learning on Clock Characteristics / Oser, Pascal (Universitaet Ulm (DE)) ; Kargl, Frank (Universitaet Ulm (DE)) ; Lueders, Stefan (CERN)
The number of devices of the so-called Internet of Things (IoT) is heavily increasing. One of the main challenges for operators of large networks is to autonomously and automatically identify any IoT device within the network for the sake of computer security and, subsequently, being able to better protect and secure those.

Sharing server nodes for storage and compute / Smith, David (CERN) ; Di Girolamo, Alessandro (CERN) ; Glushkov, Ivan (Texas U., Arlington (main)) ; Jones, Ben (CERN) ; Kiryanov, Andrey (St. Petersburg, INP) ; Lamanna, Massimo (CERN) ; Mascetti, Luca (CERN) ; McCance, Gavin (CERN) ; Rousseau, Herve (CERN) ; Schovancova, Jaroslava (CERN) et al.
Based on the observation of low average CPU utilisation of several hundred file storage servers in the EOS storage system at CERN, the Batch on EOS Extra Resources (BEER) project developed an approach to also utilise these resources for batch processing. Initial proof of concept tests showed little interference between batch and storage services on a node. [...]
