Novell has used various proprietary CMS solutions over time, including TeamSite and Vignette. None of these solutions met all of our needs, nor were they easy to modify. We began looking at different Open Source CMS options, and decided on Plone. This presentation will briefly discuss Novell's proprietary CMS history, why we chose Plone, what we are currently using and developing, and our plans for the future. It will also discuss our architecture for making Plone successful for enterprise websites.

Dégraissons le mammouth ou Darwin a encore frappé La théorie de l'évolution appliquée au développement informatique - cas pratique de l'architecture du site PMU.fr Depuis 1980, Lehman nous avertit: un programme doit évoluer ou péricliter, mais alors qu'il devient de plus en plus gros, la complexité résultante tend à limiter son évolution. Comment remédier à cela? Quelle architecture adopter pour un site à fort trafic comme celui du PMU? Après avoir abordé les problématiques d'évolution et de maintenance d'une application monolithique, nous verrons pourquoi et surtout comment séparer les composants et les comportements de notre application. Du monolithe aux micro services, du distribué, des messages, du publish/subscribe, du REST, une approche polyglotte, ... au cours de cet exposé, nous verrons quelques uns des choix retenus pour garantir la survie et l'évolution de notre application. Nous verrons comment nous avons construit un socle solide permettant de répondre aux nouvelles manières de faire du Web, d'être adapté aux applications mobiles et aux télés connectées. Ce sera l'occasion d'aborder aussi bien les principes architecturaux et les principes organisationnels qui nous ont permis d'atteindre cet objectif.

Working in Web Operations means dealing with production systems that in most cases needs to be operational 24×7x365. To reach 99.99999% uptime, you must fail as little as possible. This talk will go through a few real-world incidents and failures experienced by our small WebOps team, and outline what we are learning (the hard way), and how we’re trying to improve. What could possibly go wrong? :-)

Opera Software is mainly known for its web browser, but Opera also created and develops a growing set of web applications like its own community dedicated to the browser, my.opera.com, started in 2001. Since then, the community grew bigger and bigger, and had the "usual" scalability problems. The application has been rewritten 3 times and the current developers team is at a turning point now. How to make the application and systems scalable with the growing amount of traffic and users?

The presentation explores the development and application of artificial intelligence (AI) from its inception to its current status in the modern world. The term "artificial intelligence" was first coined by John McCarthy in 1956 to describe efforts to develop computer programs capable of performing tasks that typically require human intelligence. This concept was first introduced at a conference held at Dartmouth College, where programs demonstrated capabilities such as playing chess, proving theorems, and interpreting texts. In the early stages, Alan Turing contributed to the field by defining intelligence as the ability of a being to respond to certain questions intelligently, proposing what is now known as the Turing Test to evaluate the presence of intelligent behavior in machines. As the decades progressed, AI evolved significantly. The 1980s focused on machine learning, teaching computers to learn from data, leading to the development of models that could improve their performance based on their experiences. The 1990s and 2000s saw further advances in algorithms and computational power, which allowed for more sophisticated data analysis techniques, including data mining. By the 2010s, the proliferation of big data and the refinement of deep learning techniques enabled AI to become mainstream. Notable milestones included the success of Google's AlphaGo and advancements in autonomous vehicles by companies like Tesla and Waymo. A major theme of the presentation is the application of generative AI, which has been used for tasks such as natural language text generation, translation, and question answering. Generative AI uses large datasets to train models that can then produce new, coherent pieces of text or other media. The presentation also discusses the ethical implications and the need for regulation in AI, highlighting issues such as privacy, bias, and the potential for misuse. These concerns have prompted calls for comprehensive regulations to ensure the safe and equitable use of AI technologies. Artificial intelligence has also played a significant role in healthcare, particularly highlighted during the COVID-19 pandemic, where it was used in drug discovery, vaccine development, and analyzing the spread of the virus. The capabilities of AI in healthcare are vast, ranging from medical diagnostics to personalized medicine, demonstrating the technology's potential to revolutionize fields beyond just technical or consumer applications. In conclusion, AI continues to be a rapidly evolving field with significant implications for various aspects of society. The development from theoretical concepts to real-world applications illustrates both the potential benefits and the challenges that come with integrating advanced technologies into everyday life. The ongoing discussion about AI ethics and regulation underscores the importance of managing these technologies responsibly to maximize their their benefits while minimizing potential harms.

Microsoft's Threat Matrix for Kubernetes helps organizations understand the attack surface a Kubernetes deployment introduces to their environments. This ensures that adequate detections and mitigations are in place. By covering over 40 different attacker techniques, defenders can learn about Kubernetes-specific mitigations and controls to deploy to their environments. In this session, we will explore the MS-TA9013 Host Path Mount technique, which is commonly used by attackers to perform privilege escalation in a Kubernetes cluster. Attendees will learn how attackers and defenders can: * Escape the container's host volume mount to gain persistence on an underlying node * Move laterally from the underlying node into the customer's cloud environment * Analyze Kubernetes audit logs to detect pods deployed with a hostPath mount * Deploy an admission controller that prevents new pods from using a hostPath mount

With more memory available, system performance of three Dell devices increased, which can translate to a better user experience Conclusion When your system has plenty of RAM to meet your needs, you can efficiently access the applications and data you need to finish projects and to-do lists without sacrificing time and focus. Our test results show that with more memory available, three Dell PCs delivered better performance and took less time to complete the Procyon Office Productivity benchmark. These advantages translate to users being able to complete workflows more quickly and multitask more easily. Whether you need the mobility of the Latitude 5440, the creative capabilities of the Precision 3470, or the high performance of the OptiPlex Tower Plus 7010, configuring your system with more RAM can help keep processes running smoothly, enabling you to do more without compromising performance.
