Hebatalrahman nanotreatment
The document describes a laser indirect exposure method for treating nanomaterials. The method involves dipping powder materials in a transparent plastic to allow laser beams to pass through without being absorbed. This indirectly exposes the powder to laser irradiation, improving its mechanical properties. After exposure, an organic solvent is used to remove the treated nanomaterials from the transparent plastic. The method physically improves properties without pollution and does not waste treated materials. It was found to improve hardness and modify Raman spectra of treated materials.

The document discusses a method for improving the mechanical properties of nano and micro materials using laser irradiation. The method involves embedding powder materials in a transparent plastic to allow laser beams to pass through without being absorbed by the plastic. After irradiation, an organic solvent is used to separate the treated materials from the plastic. Raman spectroscopy and hardness tests showed that the laser treatment improved the mechanical properties by storing photon energy in the material's structure in a similar way to cold working. The method provides a physical, non-polluting way to enhance materials that does not cause economic losses.

MongoDB in a scale-up: how to get away from a monolithic hell — MongoDB Paris...
This is the slide deck of a talk by Alexis "Horgix" Chotard and Laurentiu Capatina presented at the MongoDB Paris User Group in June 2024 about the feedback on how PayFit move away from a monolithic hell of a self-hosted MongoDB cluster to managed alternatives. Pitch below.
March 15, 2023, 6:59 AM: a MongoDB cluster collapses. Tough luck, this cluster contains 95% of user data and is absolutely vital for even minimal operation of our application. To worsen matters, this cluster is 7 years behind on versions, is not scalable, and barely observable. Furthermore, even the data model would quickly raise eyebrows: applications communicating with each other by reading/writing in the same MongoDB documents, documents reaching the maximum limit of 16MiB with hundreds of levels of nesting, and so forth. The incident will last several days and result in the loss of many users. We've seen better scenarios.
Let's explore how PayFit found itself in this hellish situation and, more importantly, how we managed to overcome it!
On the agenda: technical stabilization, untangling data models, breaking apart a Single Point of Failure (SPOF) into several elements with a more restricted blast radius, transitioning to managed services, improving internal accesses, regaining control over risky operations, and ultimately, approaching a technical migration when it impacts all development teams.

Sur un exemple très concret d’audit d’éco-conception de l’outil de bilan carbone C’Bilan développé par ICDC (Caisse des dépôts et consignations) nous allons expliquer en quoi l’ACV (analyse de cycle de vie) a été déterminante pour identifier les pistes d’actions pour réduire jusqu'à 82% de l’empreinte environnementale du service.

De l'IA comme plagiat à la rédaction d'une « charte IA » à l'université
L'IA connaît une croissance rapide et son intégration dans le domaine éducatif soulève de nombreuses questions. Aujourd'hui, nous explorerons comment les étudiants utilisent l'IA, les perceptions des enseignants à ce sujet, et les mesures possibles pour encadrer ces usages.
Constat Actuel
L'IA est de plus en plus présente dans notre quotidien, y compris dans l'éducation. Certaines universités, comme Science Po en janvier 2023, ont interdit l'utilisation de l'IA, tandis que d'autres, comme l'Université de Prague, la considèrent comme du plagiat. Cette diversité de positions souligne la nécessité urgente d'une réponse institutionnelle pour encadrer ces usages et prévenir les risques de triche et de plagiat.
Enquête Nationale
Pour mieux comprendre ces dynamiques, une enquête nationale intitulée "L'IA dans l'enseignement" a été réalisée. Les auteurs de cette enquête sont Le Sphynx (sondage) et Compilatio (fraude académique). Elle a été diffusée dans les universités de Lyon et d'Aix-Marseille entre le 21 juin et le 15 août 2023, touchant 1242 enseignants et 4443 étudiants. Les questionnaires, conçus pour étudier les usages de l'IA et les représentations de ces usages, abordaient des thèmes comme les craintes, les opportunités et l'acceptabilité.
Résultats de l'Enquête
Les résultats montrent que 55 % des étudiants utilisent l'IA de manière occasionnelle ou fréquente, contre 34 % des enseignants. Cependant, 88 % des enseignants pensent que leurs étudiants utilisent l'IA, ce qui pourrait indiquer une surestimation des usages. Les usages identifiés incluent la recherche d'informations et la rédaction de textes, bien que ces réponses ne puissent pas être cumulées dans les choix proposés.
Analyse Critique
Une analyse plus approfondie révèle que les enseignants peinent à percevoir les bénéfices de l'IA pour l'apprentissage, contrairement aux étudiants. La question de savoir si l'IA améliore les notes sans développer les compétences reste débattue. Est-ce un dopage académique ou une opportunité pour un apprentissage plus efficace ?
Acceptabilité et Éthique
L'enquête révèle que beaucoup d'étudiants jugent acceptable d'utiliser l'IA pour rédiger leurs devoirs, et même un quart des enseignants partagent cet avis. Cela pose des questions éthiques cruciales : copier-coller est-il tricher ? Utiliser l'IA sous supervision ou pour des traductions est-il acceptable ? La réponse n'est pas simple et nécessite un débat ouvert.
Propositions et Solutions
Pour encadrer ces usages, plusieurs solutions sont proposées. Plutôt que d'interdire l'IA, il est suggéré de fixer des règles pour une utilisation responsable. Des innovations pédagogiques peuvent également être explorées, comme la création de situations de concurrence professionnelle ou l'utilisation de détecteurs d'IA.
Conclusion
En conclusion, bien que l'étude présente des limites, elle souligne un besoin urgent de régulation. Une charte institutionnelle pourrait fournir un cadre pour une utilisation éthique.
