Getting Organized

Soixante-troisiène édition du C++ French User Group (C++Frug) Paris. Cette session sera hybride: * [eXalt](https://www.exalt-company.com/en-us/index.html) nous accueillera au 10 Rue Vauvilliers, 75001 Paris, France * Streaming sur Discord **Pour rentrer, il faudra signer le listing.** Avant de venir, vous pouvez rejoindre les serveurs Discord ([https://discord.gg/tjx9bFpBfC](https://discord.gg/tjx9bFpBfC) & [https://discord.gg/9aU6tZabJV](https://discord.gg/9aU6tZabJV)). L'application Discord est plus stable que la version web. Programme de la soirée (heure de Paris): * 19h00 Welcome * 19h15 News of the C++ ecosystem * 19h20 Lightning talks * 20h10 Snacks & drinks * 20h40 Joel FALCOU -- From Acrobatics to Ergonomics - A Field Report on How to Make Libraries Helpful Si vous êtes intéressé pour présenter, vous pouvez nous joindre via Discord ou MP meetup. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- Lightning talks prévus (mais venez avec les votres !) * Polymorphisme statique versus dynamique * C++ 2025 : le risque de l’immobilisme * Introduction aux concepts * Introduction aux modules par Mouad BEN GELOUNE, développeur C++ Senior et Florian CHARRIEAU, développeur C++ depuis plus de 10 ans, actuellement en mission à CA-CIB. En bon avocat du clean code, il aime passer du temps (souvent trop) à rendre le code plus lisible et plus maintenable. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **From Acrobatics to Ergonomics - A Field Report on How to Make Libraries Helpful** Thanks to features like concepts, C++20 promised to make template meta-programming more approachable and expressive, especially for library designers. But as we quickly learned, template programming can still be surprising or frustrating — in the worst-case scenario, it's both. In this talk, I’ll share lessons from the past 3–4 years of building high-performance, user-friendly C++ libraries, including: * **EVE**, a SIMD abstraction layer designed for performance and portability. * **KUMI**, a re-imagined tuple library with algorithmic support. * **KIWAKU**, a toolkit for multi-dimensional arrays that aims to be efficient and ergonomic. We’ll explore the practical challenges of designing ergonomic C++ APIs: * Error messages that make sense: \`static_assert\` or concepts? How to avoid large template error stacks? ... * APIs that align with user intuition: How do we provide options on the functions' semantics? How to design meaningful extension points, ... * How bold design decisions can pay off: going sideways with standard practices, turning CTAD upside-down, ... We'll discuss how C++20 features helped us reduce friction and increase clarity once we use them properly. If you’ve ever screamed into the void over template errors, please join in! **Joel FALCOU** is an associate professor at the University Paris-Saclay and Researcher at the LISN - the Laboratoire Interdisciplinaire des Sciences du Numériques - in Orsay, France. His research focuses on studying generative programming idioms and techniques to design tools for parallel software development. And for some reasons, he does all of that in C++. The main parts of his work are: * the exploration of Embedded Domain Specific Language design for parallel computing on various architectures; * the definition of a formal framework for reasoning about meta-programs. Joel is the co-host of the C++FRUG Meetup, president of the C++FRUG Association, co-organizes the CPPP Conference, and is part entrepreneur, being one of the co-founder of CODE RECKONS, a company focused on bringing people and company up to date to the best and newest C++.

Coworking for writers in your area! (Français & English sessions) with Andréa, Amy & Gaspard. Join us for some focused writing time. All writers and all experience levels are welcome and don’t worry, no one will see what you've written. This session is about getting your writing done and meeting other writers in your area.

Once everyone’s arrived, I will lead quick introductions and then set the timer for our quiet and focused writing session. Afterward, we’ll have time to chat and get to know each other. We often talk about our successes and challenges as writers. If you don’t have time to stick around, no worries! A note about the format We don’t host critiques or readings.

**Pourquoi cet atelier ?** Mille richesses et mille compétences dorment en nous mais personne, y compris nous-mêmes, ne les a suffisamment reconnues. Elles ne demandent pourtant qu’à s’affirmer, de façon juste, pour devenir nos alliées dans notre vie personnelle et professionnelle. Mobiliser nos ressources, les conjuguer avec celles de nos proches, créer avec eux de nouvelles richesses, les partager équitablement : ce n’est pas un rêve... juste un chemin à explorer. **Pour qui ?** * Pour celles et ceux qui ont été freinés plus que soutenus dans la prise de conscience de leurs richesses de toutes sortes... * ...et qui ont besoin d’affirmer plus joyeusement leur puissance d’exister et d’agir. **Comment cela se passe ?** * Le groupe comporte entre 4 et 10 personnes. Chaque séance dure environ 2 heures ; * Les participant.e.s y travaillent alternativement par deux et en grand groupe ; * Ils explorent leurs propres richesses selon différentes approches. **Quels bénéfices pour les participants ?** * Dans cet atelier, vous pourrez nommer vos richesses et vous en réjouir ; * Puis les affirmer dans le monde social, et y vivre mieux.

➡️ Réservation obligatoire depuis la billetterie : [https://www.eventbrite.fr/e/billets-fragmentation-tenir-et-agir-dans-un-monde-qui-se-defait-1979541356485](https://www.eventbrite.fr/e/billets-fragmentation-tenir-et-agir-dans-un-monde-qui-se-defait-1979541356485) La philosophie n'offre pas de « prêt-à-penser », mais un espace pour forger une densité intérieure. Il y a cette impression diffuse que le tissu du monde se déchire. Les distances se creusent, et l'on se sent soi-même parfois isolé, comme un fil coupé de sa trame. Dans cette crise de liens, la fragmentation que nous voyons est autant individuelle que collective. Le défi est de réussir à tenir debout quand les repères vacillent. Chercher à être utile en période de repli. Car la fragmentation nous traverse aussi : pour agir utilement, il faut d'abord réussir à se rassembler à l’intérieur. Face à cela, la philosophie n'offre pas de « prêt-à-penser », mais un espace pour forger une densité intérieure. Une occasion de questionner nos ancrages, de discerner ce qui a du sens et de tenter de renouer les fils. Échangeons ensemble le **mardi 27 janvier 2026** lors de notre prochaine rencontre philo. *Cette rencontre initie un cycle de philosophie pratique qui commencera le 3 février 2026.* **Date et lieu** 📅 Date : Mardi 27 janvier à 19h30 📍Lieu : Espace Le Moulin, 48 rue du fer à Moulin 75005 Paris 🎟️ Tarif : 7€ tarif unique

Join us as we get together to get together to help those in need at this CMG Gives Back event! For this event, we’ll help prepare food, serve meals, assist residents, wash dishes and clean surfaces at Fath Mission – Grant Kitchen. We have a great little community of Movie Group friends so rather than see a movie this time, we’ll help “Create a better world” by helping serve those in need. Here are complete details and our plan for this event: FAITH MISSION – GRANT KITCHEN: The Faith Mission kitchen and dining room serves residents 3 meals a day, every day of the year. Our group will help prepare food, serve meals, assist residents in the dining room, wash dishes, and clean surfaces. PLAN: We will be preparing / serving / cleaning for BRUNCH from 10:30am to 12:30pm and have space for a total of 7 volunteers. Please arrive at 10:15am and wear closed-toe shoes and long pants. LOCATION: Faith Mission – Grant Kitchen is located at 245 N. Grant Ave. Enter the kitchen at Dock 1, indicated in the attached map. On-site and street parking are available in the surrounding area. Below are some links / attachments with additional info/details: \* LSS Volunteer Guidelines: Uploaded to photos. \* Parking Map Info: Uploaded to photos. \* LSS Faith Mission Orientation Video: https://www.youtube.com/watch?v=Bp46_6ay6iA \* Link with Additional Details / Info: https://lss.vomo.org/opportunity/faith-mission-grant-kitchen-2025 IMPORTANT REMINDER: Our group will be providing all of the volunteers on this day so a firm RSVP count is essential. Please only sign up if you are certain you’ll be able to attend. If something unavoidable comes up, please update your RSVP no later than one week prior to the event. With very few exceptions, no shows or cancelations within 1 week of the event will not be eligible for future CMG Gives Back events. I appreciate your understanding as we try to ensure the agencies have the volunteers needed to provide the essential services they provide to the vulnerable population they serve. THANK YOU: This CMG Gives Back event provides an opportunity for YOU to get involved in helping others! Benefits go well beyond the help we give to others. Volunteering provides a wide range of personal benefits, including positive effects on mental and physical health, reduced stress/depression/anxiety, increased happiness and improved purpose, life-satisfaction and personal well-being! Plus, the opportunity to get involved, connect with others and help those in need. PARTNER AGENCY: This event is hosted by Lutheran Social Services (LSS), which serves thousands of people in need each day in 27 Ohio counties by addressing the four core societal issues of food, shelter, safety and healing. LSS offers food through the LSS Food Pantries, housing and supportive services through LSS Faith Mission and LSS Faith Mission of Fairfield County homeless shelters, domestic violence services through LSS CHOICES for Victims of Domestic Violence, senior living and health care, affordable housing communities, and other services that uplift families and strengthen communities. Look forward to seeing you there, Dan

**The idea for this group is to build a community where men can gather together and build connections & learn and grow from each other.** How we start each meeting is by each of us checking in with our "roses and thorns" aka what are the good things and the bad things going on in your life recently? Then we will go into a topic discussion. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **COMMUNITY AGREEMENTS** \*\*THERE WILL BE A ZERO TOLERANCE POLICY FOR NO-SHOWS. IF YOU RSVP TO A MEETING AND FAIL TO SHOW UP WITHOUT NOTICE, YOU'LL BE REMOVED FROM THE GROUP. THIS IS TO PRESERVE THE INTEGRITY OF THE GROUP\*\* 1. Confidentiality - EVERYTHING that is shared NEVER leaves this space so that this space remains safe and sacred. There is a zero tolerance policy for this. If a man is in violation of this, they will be permanently removed from the group. 2. Non-Judgement - we respect and honor every man’s truth so that we may receive the same from others. While we may not agree on everything, we commit to respecting every man’s perspectives and engaging in honorable discussion with one another. 3. Be committed - honor your commitment to this group and to yourself. If you attend a meeting, please commit yourself fully to the meeting. Also be committed to your own journey. When we fail, we own it & clean it up. 4. Speak from the heart - this is NOT a space to “look good”, have the “right” answers, and have it all together. Relax and know you are not alone. Be exactly who you are within the safety of this space. 5. Be supportive - This means always willing to provide encouragement to your fellow men, encourage action and momentum in each other’s lives.. Be willing to challenge each other. Be willing to hold each other accountable. 6. Participation - what you receive from this community will be a reflection of what you put into it. Period. We ask that you share your perspectives, reflect on others, and give/receive support when and where it’s needed.
