OW2con'14 - Open Source software quality and OW2 SQuAT initiative, CETIC

OW2

Ensuring the sustainability of Open Source projects is important, especially when organized in ecosystems of interrelated projects. Generic methodologies like SQALE or QualOSS describe how to assess maturity covering product, process and community aspects. Specific ecosystems have defined their own quality model, like OW2’s SQUaT Mature Transition Checklist. Such quality assessment of Open Source Ecosystems should be efficiently supported. In this talk we will present the CHOOSE toolset we have developed to help in automating and uniformly managing the quality of a whole Open Source Ecosystems. Our toolset is based on 35 key indicators related to maintainability, reliability and community which are used to implement and automate the production of OW2’s Mature Transition Checklist. The generic architecture of the toolset will be presented how it is instantiated to implement the OW2 Mature Transition Checklist and to efficiently interface with the OW2 forge. The toolset implementation will also be detailed stressing the use of Open Source components for the workflows' orchestration (Bonita), project/code analysis tools (HtmlUnit, QualOSS) and automatic report generation tools (JasperReports). Finally, a validation on a subset of 21 OW2 projects with an in-depth focus on a few projects (Chameleon, Spago and Orchestra) to produce maturity reports.

OW2

Connaissez-vous OW2 ? Aventure commencée en 1999 à Grenoble sur la base d'un consortium industriel dédié au middleware open source, devenu association sans but lucratif d'échelle européenne en 2006 sous le nom d'OW2, nous agissons pour la diffusion du libre dans le monde professionnel depuis plus de 20 ans. OW2 compte des adhérents de toute taille : 2.600 individuels en adhésion gratuite, et 30 institutionnels, de la TPE unipersonnelle à Orange, Microsoft ou Huawei, de l'Inria ou le Fraunhofer Fokus à la Gendarmerie Nationale ou la ville de Paris. Nos projets sont plus célèbres que nous : ASM, Centreon, Lutece, PrestaShop, Sympa ou Rocket.Chat vous diront peut-être quelque chose ? Philosophiquement, OW2 se trouve quelque part entre Eclipse et Apache : culture technique, infrastructure d'hébergement et d'assistance pour les projets, sur la ligne de crête entre l'esprit du libre et les contraintes du business, nous sommes un acteur de l'économie sociale, persuadé que l'open source est central dans une transformation sociétale nécessaire qui ne pourra se faire sans l'adhésion du monde industriel et académique. A un tournant de notre histoire, nous investissons le créneau de la qualité industrielle des projets avec notre méthodologie "Market readiness Levels", et la gouvernance de l'open-source comme membre fondateur de l'OSPO Alliance (ospo.zone) et éditeur du guide méthodologique "OSS Good Governance handbook". Ne nous y trompons pas : OW2 est un acteur éminemment politique, porteur d'une vision fondée sur la transformation du monde professionnel et de ses valeurs par le code et la coopération. Et cette présentation, avec un survol de notre histoire, adhérents, initiatives et projets, est également l'occasion d'en débattre.

SFScon'20 Bringing the User into the Equation

OW2

The document discusses three initiatives by OW2 to engage mainstream open source software users. It describes a beta-testing campaign platform to get user feedback, a market readiness levels assessment to help users evaluate projects, and an open source governance initiative to help users adopt best practices. The overall goal is to bring users into the open source ecosystem to help projects become more sustainable.

Towards a sustainable solution to open source sustainability, OW2online20, Ju...

OW2

A few years ago, Heartbleed epitomized a massive open source sustainability problem for critical parts of the internet infrastructure. The bug, which affected the popular OpenSSL cryptographic software library, notably compromised the confidentiality of 4.5 million US patient records and cost the industry an estimated $500M. It was soon revealed that the root cause of the issue was that OpenSSL was precariously understaffed. Open source sustainability became a major theme overnight. Stories of maintainer burn-out made the headlines. And tentative solutions started to emerge, most of them donation-based. In this talk we’ll explore a number of existing strategies to fund open source and make it more sustainable, from patronage to dedicated ad networks. And we’ll defend the idea that the best path to open source sustainability is to help companies understand the tangible business value they can get from contributing to open source.

Open Source governance and the Eclipse Foundation, OW2online, June 2020

OW2

Presentation by Gael Blondelle, Managing Director at Eclipse Foundation. Abstract: In this talk, we will cover two complementary topics: The different Eclipse projects related to Open Source governance, like Eclipse SW360, SW360 Antenna, and Eclipse Steady, as well as the opportunity to leverage SW360 as the core of a larger Open Source governance initiative. The Eclipse IP Process that has been applied to hundreds of Eclipse projects for more than 15 years and is going through a modernization process that involves both simplification from the developer point of view, and openness to new source of trusted data like Clearly Defined.

Open source contribution policies, OW2online, June 2020

OW2

Open source contribution policies are long, boring, overlooked documents, that generally suck. They're designed to protect the company at all costs. But in the process, end up hurting engineering productivity, and morale. Sometimes they even unknowingly put corporate IP at risk. But that's not inevitable. It's possible to write open source contribution policies that make engineers lives easier, boost morale and productivity, reduce attrition, and attract new talent. And it's possible to do so while reducing the company's IP risk, not increasing it. In this talk, we'll look at the general structure of contribution policies, examples in the wild, and tactics to make them suck less. We'll also look at how to turn these policies into self-service software, preventing the tedious email back and forth between engineering and legal in most cases and making open source contribution a breeze. Presentation by Tobbie Langel, UnLockOpen.

Software development at scale, pandemic lockdown and oss ecosystems, OW2onlin...

OW2

The document discusses using open source development techniques within companies through an approach called InnerSource. It suggests that InnerSource can help companies be more resilient, as open source projects have been during the COVID-19 pandemic, by breaking down silos and fostering distributed development communities within organizations. To effectively manage InnerSource, companies should use a data-driven approach and define metrics for people, processes, and community engagement to track success over time in a continuous improvement model.

Ideas, methods and tools for OSS Compliance assessment, OW2online, June 2020

OW2

Presentation by Boris Baldassari, Consultant, Castalia Solutions. Abstract: While Open Source Software has become mainstream, the understanding of its key principles, from ethics and collaboration to governance and community management, is gaining more interest and attention. There is a comprehensive volume of studies and reports backing up our individual and collective experience, yet we still cannot reliably measure these characteristics, and even less clearly define or assess them. In an attempt to build up confidence and foster maturity in this area, this talk will look at the various existing models and metrics related to OSS compliance and governance, and build upon them to propose methods and tools for their evaluation and analysis. We will discuss the requirements and essential questions to ask, offer guidelines for implementation and suggest efficient ways to present results.

Intelligent package management with FASTEN, OW2online, June 2020

OW2

Presentation by Amir Mir, TUDelft. As recent events, such as the leftpad incident and the Equifax data breach, have demonstrated, dependencies on networks of external libraries can introduce projects to significant operational and compliance risks as well as difficult to assess security implications. FASTEN introduces fine-grained, method-level, tracking of dependencies on top of existing dependency management networks. In our talk, we will present how FASTEN works on top of the Rust/Cargo and Java/Maven ecosystems.

Enabling DevOps for IoT software development, powered by Open Source, OW2onli...

OW2

Presentation by Hui Song, Senior Scientist, SINTEF. We would like to share our research journey towards enabling DevOps for IoT applications, and how Open Source makes the journey feasible and fun. DevOps is widely adopted for developing cloud applications, which supports developers in continuously placing software changes directly to production. As companies are including IoT and Edge devices into their IT infrastructures, supporting DevOps for IoT is a must. However, IoT challenges some fundamental assumptions behind DevOps, such as the homogeneous infrastructure and centralized governance, and therefore, breaking-through research is needed. Funded by H2020, 30 people from 12 partners crossing academia and industry gathered to solve these fundamental challenges, which results in full-stack open source tools for automatic deployment, learning-based operation and security monitoring of IoT applications, and risk management of the development process. The tools are evaluated on industrial use cases in intelligent transportation, smart building, and eHealth. The mass open source tools and communities around IoT development provides the sound foundation for this design research and the opportunities for the further exploitation of the results. In particular, we are proud of spinning off a start-up to commercialize the risk management services in the open source + SaaS model.

Upcoming Challenges in Artificial Intelligence Research and Development, OW2o...

OW2

Artificial Intelligence is now smarter than ever, showing human-like abilities at complex tasks such as images classification or natural language processing. But despite its recent advances, it's still not a silver bullet. This talk will present a few challenges in the research and development of artificial intelligence that slow down its progress and adoption. In particular, problems around fairness, the training of models and how to share them will be introduced as well as possible Free Software solutions. Presentation by Vincent Lequertier, PhD Student, Lyon UNiverversity.

Cacti and Big Data at Orange France, OW2online, June 2020

OW2

We propose a walkthrough of current utilization of Open Source Software in capacity planning for the Orange network infrastructure. The objective of our project is to have a platform that helps engineers to carefully plan the resources available to them as well as to correlate different incidents within remote parts of the infrastructure. In order to achieve this we started using Cacti with the Spine collector which worked great, but Orange France is a very large company with many entities, each with its own governance, and so we began to see some limitations. There was a need to centralize some information from different parts in Orange France as well as to integrate the equipment capacity and load values into BigData Orange. In order to achieve this we developed the “Puits de donneés” platform completely based on Open Source Software. The visualization and statistical analysis part is handled by Grafana while the ETL runs on Apache Software Foundation products like NiFi, Zookeeper and Ambari with a storage solution from MariaDB for which we did extensive performance tuning and customization due to the large amounts of data.

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...

Alex Pruden

Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security. Paper Link: https://eprint.iacr.org/2024/257

Introduction of Cybersecurity with OSS at Code Europe 2024

Hiroshi SHIBATA

I develop the Ruby programming language, RubyGems, and Bundler, which are package managers for Ruby. Today, I will introduce how to enhance the security of your application using open-source software (OSS) examples from Ruby and RubyGems. The first topic is CVE (Common Vulnerabilities and Exposures). I have published CVEs many times. But what exactly is a CVE? I'll provide a basic understanding of CVEs and explain how to detect and handle vulnerabilities in OSS. Next, let's discuss package managers. Package managers play a critical role in the OSS ecosystem. I'll explain how to manage library dependencies in your application. I'll share insights into how the Ruby and RubyGems core team works to keep our ecosystem safe. By the end of this talk, you'll have a better understanding of how to safeguard your code.

Mutation Testing for Task-Oriented Chatbots

Pablo Gómez Abajo

Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots. To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

High performance Serverless Java on AWS- GoTo Amsterdam 2024

Vadym Kazulkin

Java is for many years one of the most popular programming languages, but it used to have hard times in the Serverless community. Java is known for its high cold start times and high memory footprint, comparing to other programming languages like Node.js and Python. In this talk I'll look at the general best practices and techniques we can use to decrease memory consumption, cold start times for Java Serverless development on AWS including GraalVM (Native Image) and AWS own offering SnapStart based on Firecracker microVM snapshot and restore and CRaC (Coordinated Restore at Checkpoint) runtime hooks. I'll also provide a lot of benchmarking on Lambda functions trying out various deployment package sizes, Lambda memory settings, Java compilation options and HTTP (a)synchronous clients and measure their impact on cold and warm start times.
