Dimitri FONTAINE The PostgreSQL project organisation has been evolving several times in the last 20 years to accommodate to an ever growing community of contributors and users. In this talk, we will review the history of the project organisation to better understand how this project is managed, then detail the current state of things. Strengths and weaknesses will get analyzed.

Remember the old days when you tested using JUnit? How boring it was? You made a lot of excuses to avoid testing your code. Luckily those dark days now belong to the past because Spock is with us.Spock is a Groovy-based testing and specification framework for Java and Groovy applications that makes writing tests fun again. We can write beautiful and highly expressive tests because of its DSL and all the power that Groovy provides us.In this talk you'll learn the basics of Spock and you'll see how easily you can test a Java application. After the talk you won't have any excuse to don't test your applications, so you have been warned before coming to the talk!

La presentazione di Bruno Bossola in occasione del Codemotion del 5 marzo 2011 http://www.codemotion.it Un'introduzione all'uso di GIT, il nuovo sistema di controllo versione che sta diventando rapidamente il punto di riferimento per lo sviluppo FLOSS e nell'Enterprise. Durante l'intervento saranno spiegate le principali caratteristiche di GIT , integrandole con dimostrazioni pratiche live che spiegheranno il funzionamento dei comandi principali. La parte finale della presentazione sarà legata alle problematiche relative all'adozione dello strumento in ambiente enteprise.

#keepitsimple, Final project for BIG DIVE 2 A project by: Alex Comunian The TOP-IX dataset contains all the Consortium streaming platform server logs. The project was divided into two parts: the first aimed at searching trends or mathematical models suitable for the web radio througput; the second aimed at creating a report about the exchange of streaming platform traffic in 2012. The final display is the amount of traffic transferred during the year, highlighting the “points of interest”.

Video: https://www.simonsfoundation.org/event/collaborations-in-the-extreme-the-rise-of-open-code-development-in-the-scientific-community/ The internet is changing the scientific landscape by fostering international, interdisciplinary and collaborative software development. More than ever before, software is a crucial component of any scientific result. The ability to easily share code is reshaping expectations about reproducibility -- a fundamental tenet of the scientific process. In this lecture, Kelle Cruz will briefly provide the backstory of how these shifts have come about, describe some of the most impactful open source projects, and discuss efforts currently underway aimed at ensuring these community-led projects are sustainable and receive support.

Always wanted to control your IoT device without SSH'ing into it? In this talk we will show how WebSockets, MQTT and a set of custom go/js libraries can help in managing remotely your IoT device without knowing its IP address. Learn how you can use the Arduino Create Agent to easily deploy containers, remotely. A journey on Docker client, APT command line, sockets, systemd and much more on Arm and Intel Linux devices.

IoT is at the peak of the hype cycle - what they call the 'Peak of Inflated Expectations’. The complexity of the cybersecurity landscape is at an all-time high, with security researchers, vendors and even governments all trying to come to a consensus for making the cyber-world a safer place. In this world of lightning-fast development cycles, it may intuitively feel like security gets left behind. The battle over standards is always a struggle. The unresolved problem of software updates and short vendor support cycle combined with the lack of effort into security makes these devices an easy target. Companies not only need to update their technology stack for the evolving security landscape but also their mindset, processes and culture. This talk will shine a light on some of the challenges that today’s executives face in finding and fixing systemic problems in and outside of security through people, tools and understanding.

"Cette présentation a pour but de présenter MirageOS et ses applications à l'écriture d'applications IoT sécurées. En particulier, MirageOS permet de développer des applications d'infrastructure réseau --- firewalls, proxy VPN, serveurs d'emails, etc. --- qui peuvent être déployées sur des processeurs embarqués de type ARMv8, ESP32 ou RISC-V. Nous expliquerons comment nous nous appuierons sur cette couche d'infrastructure entièrement open-source pour développer OSMOSE, une plateforme sécurisée et décentralisée permettant de construire des application IoT centrées sur l'utilisateur et le respect de sa vie privée.

WarpScript est un langage de programmation open source conçu pour facilement requêter, manipuler et traiter des données de séries temporelles à la volée. Bien qu'il soit compatible nativement avec Warp 10, WarpScript peut aussi être connecté à d'autre sources de données. Dans cette présentation, nous allons détecter des anomalies à la volée en utilisant des fonctions WarpScript et répondre aux questions suivantes. Que doit-on définir comme une anomalie ? Quel algorithme correspond au type d'anomalie que l'on cherche à détecter ? Comment prendre en compte la possible saisonnalité de mes données ?

ONLYOFFICE développée par Ascensio System SIA, est une suite bureautique open-source basée sur l'élément Canvas de HTML5, qui offre une gamme complète d’outils d’édition en ligne des documents texte, feuilles de calcul et présentations. Cette présentation commence par l’aperçu des principes de base : - support de tous les formats courants, - riche éventail d’outils de la mise en forme, - affichage du contenu de manière identique, quel que soit le navigateur utilisé, - ressources permettant d’étendre les fonctionnalités des éditeurs, - capacités avancées de co-édition, - transfert de données sécurisé en temps réel. Le nombre des universités et des écoles qui optent pour les alternatives open source aux solutions populaires offertes par les grandes marques, augmente chaque année. Les solutions de ONLYOFFICE sont actuellement utilisées par plus de 30 établissements d’enseignement en France tels que treize Universités de la Sorbonne, l’Université de Grenoble, l’Université de Nantes, l’École Nationale d'Ingénieurs de Brest, le l'établissement public Campus Condorcet, etc. Dans cette partie, Jeremy Maton, l’Administrateur Systèmes et Réseaux à l’Institut de Biologie de Lille, va présenter comment ONLYOFFICE est intégrée au sein de leur unité de recherches et aide à organiser le flux de travail.
