Apple dévoilerait de nouveaux produits très attendus avant la fin du mois, voici ce qu’il faut savoir

Après la keynote de la rentrée et l'événement « Welcome Home », voici venir une nouvelle journée de présentation de produits Apple. Ce 27 octobre, Apple devrait notamment dévoiler un MacBook équipé d’un écran tactile OLED, un nouvel iPad mini, lui aussi équipé d’un écran OLED, ainsi qu’un MacBook Pro M6.

Meeting Recorder - Vos visios transcrites en local sous Omarchy

Par : Korben ✨

Meeting Recorder , c'est un enregistreur de réunions pensé pour Omarchy, la distribution Linux de DHH basée sur Arch et Hyprland. Et y'a pas besoin d'inviter à bot chelou dans votre visio puisque l'app se contente d'écouter votre micro et ce que joue votre ordinateur. Donc ça fonctionne avec n'importe quel logiciel de réunion, et tout est ensuite transcrit sur votre machine, 100% en local

Le micro et le son de l'ordinateur sont ainsi enregistrés sur deux pistes séparées, et deux jauges vous montrent avant de lancer que les deux arrivent bien. C'est comme ça que l'outil sait qui parle... ce qui passe par le micro, c'est vous, et ce que joue l'ordinateur, ce sont les autres. Et s'il y a plusieurs personnes en face, Nemotron 3 Diarization, un modèle de NVIDIA qui tourne en local, sépare simplement leurs voix en "Remote 1", "Remote 2"...etc, que vous pouvez ensuite renommer.

L'écran de fin, Maya au micro, Tom côté ordinateur, et les deux pistes dans la forme d'onde

À la fin de l'appel, c'est whisper qui transcrit tout ce basar, avec le modèle large-v3-turbo par défaut (environ 1,6 Go à télécharger une seule fois), pendant qu'une animation façon années 90 vous fait patienter. Et pas besoin de carte graphique puisque d'après l'auteur, le processeur d'une machine récente boucle un appel court en quelques secondes. Ah et puis trop cool, le français fait partie des langues proposées, donc vous pouvez l'utiliser si vous avez séché les cours d'anglais.

Vous récupérez ensuite le texte, avec l'heure et l'intervenant sur chaque ligne, et un lecteur audio au-dessus. Cliquez alors sur une ligne et la lecture repartira de là. Et si whisper s'est gourré, vous survolez la ligne pour la corriger, la donner à l'intervenant suivant ou la supprimer. Chaque réunion finissant dans un simple dossier de ~/Documents/Meetings, avec l'audio et un fichier transcript.md, vous pouvez tout récupérer et même glisser sur la fenêtre un vocal ou un appel enregistré ailleurs, et Nemotron pourra y détecter jusqu'à 8 voix sans problème.

Pour les réunions de trois minutes ou plus, il y a aussi du chapitrage et c'est l'agent de code réglé par défaut dans Omarchy (Claude Code, Codex...) qui découpe la transcription une fois que c'est terminé. Donc, si vous ne voulez pas que ça parte dans le cloud, il faut prendre le temps de ne régler aucun agent par défaut sur Omarchy.

Et n'oubliez pas non plus de prévenir les gens en début de réunion, car l'article 226-1 du Code pénal punit l'enregistrement de paroles privées sans leur consentement. Hé ouaiiiis !

Côté installation, l'outil est dans le dépôt de paquets d'Omarchy, pour l'instant uniquement sur le canal edge. Sinon, en attendant la prochaine version d'Omarchy, ce script d'une ligne installera le même paquet.

Bref, c'est l'un ou l'autre :

yay -S omarchy-meeting-recorder
ou
curl -fsSL https://raw.githubusercontent.com/jankeesvw/omarchy-meeting-recorder/main/install.sh | bash

Attention, au moment où j'écris ces lignes, la version 1.1.1 plante dès la première transcription sur les processeurs sans AVX-512, un Ryzen 5 5500 ou un Core Ultra 9 285K par exemple. L'audio est bien enregistré, mais vous n'aurez pas de texte, parce que le binaire publié a hérité des instructions AVX-512 de la machine qui l'a compilé. Heureusement, un contributeur a déjà proposé un correctif, donc, soyez patient. Mais si vous êtes vraiment pressé, il faudra juste compiler vous-même l'appli (cargo build --release, les étapes sont dans le README).

Et si vous n'êtes pas sous Omarchy ? Faut chialer ?

Non, car l'app prendra alors l'apparence standard de libadwaita, mais sans l'agent par défaut d'Omarchy. Donc adieu les chapitres. Sous Windows, l'application Meetily fait le même genre de travail en local, Avec mon application macOS Kassis , on peut faire ça aussi. Il suffit de glisser-déposer l'enregistrement de la réunion sur l'appli. Les interlocuteurs sont reconnus et on obtient un transcript en quelques secondes. Enfin, pour transcrire vos enregistrements directement sur un serveur, il y a Speakr, dont je vous ai déjà parlé .

Voilà, en tout cas, je trouve que son dev a bien bossé ! Meeting Recorder c'est sous licence MIT, et le code est sur GitHub pour ceux qui ont un Omarchy sous la main !

Scientists ejected from diabetes conference for distributing journal reprints

Five leading scientists were ousted from the annual meeting of the American Diabetes Association (ADA) in New Orleans on Friday. Their crime: handing out copies of an editorial, published in the journal Diabetes Care on April 29, sharply criticizing the Trump administration's ongoing attacks on scientific research.

Those ousted were Steven Kahn, professor of medicine at the University of Washington and editor-in-chief of Diabetes Care, who co-authored the published editorial; former ADA President Desmond Schatz of the University of Florida, Gainesville; Aaron Kelly, pediatrics professor at the University of Minnesota; Justin Ryder of Northwestern University; and Irl Hirsch, also of the University of Washington. The five were handing out reprints of the editorial outside a room where NIH director Jay Bhattacharya had been scheduled to speak. Bhattacharya canceled and another NIH official spoke in his stead.

"They physically grabbed us, forced us out of the conference center, and now are telling us we can no longer attend this meeting," Kelly told MedPage Today, which first reported the incident. "They're taking our lanyards. It really has come to this in America. Censorship is real. America needs to stand up. Scientists, stand up. Physicians, stand up."

Code Club Conference 2025: Creativity, community, and collaboration in Cambridge

Over the first weekend in November, members of the global Code Club community came together for two inspiring days of learning, creativity and connection. The annual event celebrates the people who make Code Clubs happen, allowing them to share ideas, explore new tools, and connect with others who help young people learn to code.

Exploring new technologies and inclusive teaching

Saturday began with hands-on sessions that brought creativity and technology together, exploring large language models and prompt engineering in Collaborating with LLMs and being a prompt boss. There was a lot of laughter from attendees about how large language models can produce confident but incorrect answers if given vague prompts, but many left inspired to experiment with new technologies in their own clubs.

“First time there and it was amazing. Met loads of great people and the amazing code club crew. I learnt loads of new skills around AI and Arduino.” – An attendee

Explore AI with creators in your club using our AI and machine learning projects.

Collaboration that counts brought mentors together to discuss common challenges like volunteer retention, limited resources, and communication barriers. A crowd favourite was a shared volunteer toolkit, as well as event checklists and safeguarding resources.

“What I enjoyed most about the Clubs Conference was the opportunity to meet other facilitators and hear their stories — their successes and challenges. These conversations validated the volunteer work I do and reminded me of the impact of our clubs.” – An attendee

From the theatre sessions, you can watch Inclusive learning – Supporting Deaf learners in clubs which was both moving and insightful. We learnt that visual demonstrations, colour cues, and repetition were key to supporting Deaf learners. One memorable quote captured the spirit of the session:

“The children couldn’t speak to us. The children — we couldn’t hear their voices but by the eighth week we were able to hear their voices from what they built on the screen and it was echoing all around the classroom.” – Chidi Duru

Find out more about Chidi’s joy of coding alongside Deaf creators.

Learning and making across continents

The weekend’s talks showcased the reach of Code Club worldwide, with volunteers sharing their experiences of collaboration, sustainability, and creativity.

Watch Lessons from resourceful Code Clubs in India, which highlighted the ingenuity of young learners in under-resourced settings, while Hands-on with the Raspberry Pi Pico showcased low-cost, high-impact projects from Kenya and South Africa.

Speakers showed how community clubs adapt to local needs with unplugged activities and coding games inspired by cricket and kabaddi, empowering young people to solve real problems and celebrate curiosity through play. Excitingly, these new resources will be launching early next year; keep an eye on our activities page to be among the first to try them out!

In the session Code Club Projects Unplugged, facilitators shared the idea of “hiding the vegetables” — hiding the learning inside the fun. Whether through a collaborative Scratch game, a micro:bit prop on stage, or a Pico gadget solving a real problem, this approach helps young people learn through play. They remember the joy, and the skills come naturally.

Learning beyond the screen

Teaching tech away from the computer screen shared a fun unplugged cybersecurity activity, The Chicken Shop, where learners role-play social engineering scenarios. Its success came from clear printed instructions, movement, humour, and strong debriefing. 

Educators sharing ideas during a workshop

Learning coding outside the box explored how to engage young people with diverse learning styles while the Arduino crash course gave attendees a taste of physical computing and C++ programming in action. Workshops on AI, sustainability, and youth empowerment with Raspberry Pi computers and Unlocking Code Club resources helped club leaders discover practical ways to inspire problem-solving and make use of all the support available through Code Club.

The message from the sessions was clear: young people learn best when technology is human and hands-on.

Showcasing creativity with Coolest Projects

Coolest Projects – get involved! championed creativity over competition. Any young person under 18 can submit their project, including unfinished ideas. In-person and online showcases celebrate progress, imagination, and teamwork.

Speaking on the closing panel, Code Club leader Rachael Coultart talked about the importance of Coolest Projects as a rare platform for children to talk about their learning. She spoke about the experience of one particular child, explaining that it had made a powerful impression on her, saying:

“It had such a huge impact. I felt so proud of her and what she’d achieved. Afterwards, her parents told me that they felt it was the first time she had really been seen.”

What the community is taking forward

The community is united in its commitment to making Code Clubs inclusive, creative, and sustainable. 

  • Context matters — projects that reflect local interests and challenges motivate young people to learn
  • Accessibility is central: visual cues, repetition, interpreters, and inclusive resources support every learner
  • Structure builds confidence; start with simple, guided activities before open-ended exploration
  • Volunteers are vital; shared toolkits, checklists, and training help them deliver engaging sessions
  • Celebration and affordability matter too: regular showcases and tools like the micro:bit, Pico, and Crumble keep computing fun, hands-on, and accessible for all

“Thank you. Clubs Conference is a highlight of my year.” – An attendee

Perspectives on supporting young people in low-income areas to access and engage with computing

The Raspberry Pi Foundation’s mission is to make computing and digital making accessible to all. To support young people at risk of educational disadvantage because they don’t have access to computing devices outside of school, we’ve set up the Learn at Home campaign. But access is only one part of the story. To learn more about what support these young people need across organisations and countries, we set up a panel discussion at the Tapia Celebration of Diversity in Computing conference.

Two young African women work at desktop computers.

The three panelists provided a stimulating discussion of some key issues in supporting young people in low-income areas in the UK, USA, and Guyana to engage with computing, and we hope their insights are of use to educators, youth workers, and organisations around the world.

The panellists and their perspectives

Our panellists represent three different countries, and all have experience of teaching in schools and/or working with young people outside of the formal education system. Because of the differences between countries in terms of access to computing, having this spread of expertise and contexts allowed the panelists to compare lessons learned in different sectors and locations.

Lenlandlar Singh

Panelist Lenandlar Singh is a Senior Lecturer in the Department of Computer Science at the University of Guyana. In Guyana, there is a range of computing-related courses for high school students, and access to optional qualifications in computer science at A level (age 17–18).

Yolanda Payne.

Panelist Yolanda Payne is a Research Associate at the Constellations Center at Georgia Tech, USA. In the US, computing curricula differ across states, although there is some national leadership through associations, centres, and corporations.

Christina Watson.

Christina Watson is Assistant Director of Design at UK Youth*, UK. The UK has a mandatory computing curriculum for learners aged 5–18, although curricula vary across the four home nations (England, Scotland, Wales, Northern Ireland).

As the moderator, I posed the following three questions, which the panelists answered from their own perspectives and experiences:

  • What are the key challenges for young people to engage with computing in or out of school, and what have you done to overcome these challenges?
  • What do you see as the role of formal and non-formal learning opportunities in computing for these young people?
  • What have you learned that could help other people working with these young people and their communities in the future?

Similarities across contexts

One of the aspects of the discussion that really stood out was the number of similarities across the panellists’ different contexts. 

The first of these similarities was the lack of access to computing amongst young people from low-income families, particularly in more rural areas, across all three countries. These access issues concerned devices and digital infrastructure, but also the types of opportunities in and out of school that young people were able to engage with.

Two girls code at a desktop computer while a female mentor observes them.

Christina (UK) shared results from a survey conducted with Aik Saath, a youth organisation in the UK Youth network (see graphs below). The results highlighted that very few young people in low-income areas had access to their own device for online learning, and mostly their access was to a smartphone or tablet rather than a computer. She pointed out that youth organisations can struggle to provide access to computing not only due to lack of funding, but also because they don’t have secure spaces in which to store equipment.

Lenandlar (Guyana) and Christina (UK) also discussed the need to improve the digital skills and confidence of teachers and youth workers so they can support young people with their computing education. While Lenandlar spoke about recruitment and training of qualified computing teachers in Guyana, Christina suggested that it was less important for youth workers in the UK to become experts in the field and more important for them to feel empowered and confident in supporting young people to explore computing and understand different career paths. UK Youth found that partnering with organisations that provided technical expertise (such as us at the Raspberry Pi Foundation) allowed youth workers to focus on the broader support that the young people needed.

  • Educators sit at laptops to learn about coding and digital making.
  • An educator helps a young person with a computing problem.

Both Yolanda (US) and Lenandlar (Guyana) discussed the restrictive nature of the computing curriculum in schools, agreeing with Christina (UK) that outside of the classroom, there was more freedom for young people to explore different aspects of computing. All three agreed that introducing more fun and relevant activities into the curriculum made young people excited about computing and reduced stereotypes and misconceptions about the discipline and career. Yolanda explained that using modern, real-life examples and role models was a key part of connecting with young people and engaging them in computing.

What can teachers do to support young people and their families?

Yolanda (US) advocated strongly for listening to students and their communities to help understand what is meaningful and relevant to them. One example of this approach is to help young people and their families understand the economics of technology, and how computing can be used to support, develop, and sustain businesses and employment in their community. As society has become more reliant on computing and technology, this can translate into real economic impact.

Both Yolanda (US) and Lenandlar (Guyana) emphasised the importance of providing opportunities for digital making, allowing students opportunities to become creators rather than just consumers of technology. They also highly recommended providing relevant contexts for computing and identifying links with different careers.

The panellists also discussed the importance of partnering with other education settings, with tech companies, and with non-profit organisations to provide access to equipment and opportunities for students in schools that have limited budgets and capacity for computing. These links can also highlight key role models and help to build strong relationships in the community between businesses and schools.

What is the role of non-formal settings in low-income areas?

All of the panellists agreed that non-formal settings provided opportunities for further exploration and skill development outside of a strict curriculum. Christina (UK) particularly highlighted that these settings helped support young people and families who feel left behind by the education system, allowing them to develop practical skills and knowledge that can help their whole family. She emphasised the strong relationships that can be developed in these settings and how these can provide relatable role models for young people in low-income areas.

Tips and suggestions

After the presentation, the panelists responded to the audience’s questions with some practical tips and suggestions for engaging young people in low-income communities with computing:

How do you engage young people who are non-native English speakers with mainly English computing materials?

  • For curriculum materials, it’s possible to use Google Translate to allow students to access them. The software is not always totally accurate but goes some way to supporting these students. You can also try to use videos that have captioning and options for non-English subtitles.
  • We offer translated versions of our free online projects, thanks to a community of dedicated volunteer translators from around the world. Learners can choose from up to 30 languages (as shown in the picture below).
The Raspberry Pi Foundation's projects website, with the drop-down menu to choose a human language highlighted.
Young people can learn about computing in their first language by using the menu on our projects site.

How do you set up partnerships with other organisations?

  • Follow companies on social media and share how you are using their products or tools, and how you are aligned with their goals. This can form the basis of future partnerships.
  • When you are actively applying for partnerships, consider the following points:
    • What evidence do you have that you need support from the potential partner?
    • What support are you asking for? This may differ across potential partners, so make sure your pitch is relevant and tailored to a specific partner.
    • What evidence could you use to show the impact you are already having or previous successful projects or partnerships?

Make use of our free training resources and guides

For anyone wishing to learn computing knowledge and skills, and the skills you need to teach young people in and out of school about these topics, we provide a wide range of free online training courses to cover all your needs. Educators in England can also access the free CPD that we and our consortium partners offer through the National Centre for Computing Education.

To help you support your learners in and out of school to engage with computing in ways that are meaningful and relevant for them, we recently published a guide on culturally relevant teaching.

We also support a worldwide network of volunteers to run CoderDojos, which are coding clubs for young people in local community spaces. Head over to the CoderDojo website to discover more about the free materials and help we’ve got for you.

We would like to thank our panellists Lenandlar Singh, Yolanda Payne, and Christina Watson for sharing their time and expertise, and the Tapia conference organisers for providing a great platform to discuss issues of diversity, equality, and inclusion in computing.


*UK Youth is a leading charity working across the UK with an open network of over 8000 youth organisations. The charity has influence as a sector-supporting infrastructure body, a direct delivery partner, and a campaigner for social change.

My 5 Favorite Talks at DjangoCon Europe 2019

Django people at the DjangoCon Europe 2019

This year DjangoCon Europe happened in Copenhagen, Denmark, at a very creative and special place AFUK - Academy for Untamed Creativity. Surrounded by artistic souls, we learned more about web technologies, got to know each other at ecologic reusable disposable cups of coffee, enjoyed delicious authentic food, and socialized with Django-branded beverages. As always, there was also a party with people drinking IPA (not to be confused with API). And at the weekend Django developers were solving bugs for Django and related open-source software at the coding sprints.

Here I would like to present you with the top 5 talks that I liked most of all.

Django and Web Security Headers

Adam Johnson (@AdamChainz) was talking about special response headers that tell browsers to treat data of the website more securely and which Django settings are responsible for those headers.

Recap of DjangoCon Europe 2017

"DjangoCon, why is everybody wearing this t-shirt?" wondered the security guys in the airport of Florence, Italy, in the beginning of April. The reason for that was DjangoCon Europe 2017 happening there for a week, full of interesting talks in an exciting location.

What I liked, was that the conference was not only about technical novelties in Django world, but also about human issues that programmers deal with in everyday life.

Interesting Non-tech Topics

According to a manifest, the conference had a goal to strengthen the Django community and to shape responsible attitude towards the works done with Django.

Healthy and Successful Community

We have to build stronger communities including everyone who wants to participate without discrimination. Although, at first, it might be difficult as people have biases, i.e. prejudices for or against one person or group; by being emphatic we can accept and include everyone no matter what is their gender identity or expression, sexual orientation, ethnicity, race, neurodiversity, age, religion, disabilities, geographical location, food diversities, body size, or family status.

Valuing diversity and individual differences is the key for a healthy, positive and successful community, that empowers its members and helps them grow stronger and happier.

Responsibility for How We Use Technology

Information technology companies (Apple, Alphabet, Microsoft, Amazon, and Facebook) are among the most traded companies in the world. IT connects people and their things, automates processes, stores and treats historical data. Usually you don't need many physical resources to start an IT business. Software developers have a power to shape the future, but should use this power responsibly:

With this, great responsibility is upon us: to make the future a better place, to make the future more evenly distributed, across gender gaps and discriminations, breaking economical, political and geographical barriers.

Business

  • When creating an online business, it is important to think about the business value that your product will give to people and the way you will make money with it. Don't make assumptions without talking to your customers.
  • When choosing employees for your company, give them freedom how to prove their knowledge: by a quiz, or whiteboard interview, or a take-home programming task. Different people have different ways how to best represent their skills.
  • Launch as early as possible. Track the usage statistics with Google Analytics or other analytics service. Collect emails for the mailing list. Write about your product in a blog and personalized emails.
  • Django is an open-source project based on the hard work of many professionals, and if you gain any commercial value of it and appreciate the framework, you should donate to the Django Software Foundation.

Interesting Tech Topics

From the technical point of view, I liked several ideas mentioned in the conference:

Automate your processes

  • For starting new projects, you can have boilerplates with the mostly used functionalities already prepared. Django management command startproject has a parameter --template for that where you can pass a URL to a zip file.
  • Developers should have troubleshooting checklists for debugging, just like airplane pilots.
  • There are several types of tests. Unit tests check the functionality of individual functions or methods. Integration tests check how different units work together. The functional tests check how the processes of business requirements work from start to end. Finally, there is manual testing requiring people to click through the website and fill in the forms. Some tests like the ones involving third-party authentication or mobile phones, are hardly possible to automate. Anyway, manual testing is the most expensive in time and resources (besides it being boring for the tester), functional tests go after them, then integration tests, and lastly unit tests. Although automatic testing adds up to the development time, in the long run it makes the systems more stable and error proof.

What about Django

  • You can extend the Django ORM with custom lookups, transactions, and filtered prefetchings, to make your QuerySets more readable and more capable.
  • Once again, PostgreSQL has more capabilities than MySQL and is more stable. Use EXPLAIN ANALYZE ... SQL command to find the bottlenecks of your database queries. You can usually fix them by adding indexes.
  • You can have custom indexes for your database tables, to optimize the performance on PostgreSQL (or some other vendor) database.
  • Django 1.11 is out and it's a long-term support version.

What about Third Party Django Packages

  • After analyzing the 6 most popular model translation packages (parler, hvad, klingon, modeltranslation, nece, and i18nfield) from different angles (database support, integration in django admin and forms, performance, etc.), django-hvad seemed to be the winning approach.
  • You can visually build static websites with very little coded configuration using django-cms and djangocms-cascade. The djangocms-cascade provides an alternative nested-plugins system for Django CMS.

What about Django Projects

  • If you build web apps for developing countries, you have to keep these things in mind: people might be using cell phones instead of computers (you need responsive design with small or no images), Internet connectivity is slow and unstable (websites have to be fast and should preferably have offline versions), the users do not always understand English (the websites should be translated and adapted), and locations where people live do not always have street addresses.
  • Some interesting use cases: tracking the health of the heart with Arduino and Django, providing weather data to the whole Europe using Django, managing a radio station in Birmingham using Django.

Thanks

Finally, thanks to the organizers for making this conference as great as it was. The city was beautiful, the food and coffee was delicious, the location for the talks was impressive. Looking forward to the next DjangoCon Europe!

Keynote speeches from Scratch Conference Europe 2019

Par : Alex Bate

This weekend, the Raspberry Pi Foundation hosted Scratch Conference Europe 2019 at Churchill College in Cambridge, UK.

Framing the busy weekend’s schedule were presentations from:

  • Massachusetts Institute of Technology (MIT) Media Lab’s Mitchel Resnick, co-inventor of Scratch himself
  • Science presenter Neil Monterio
  • Raspberry Pi favourite, the fire-loving Fran Scott

Since not everyone was able to travel to Cambridge to attend the conference, we wanted to make sure you’re not missing out, so we filmed their presentations, for you to watch at your leisure.

For the full Scratch Conference experience, we suggest gathering together a group of like-minded people to watch the videos and discuss your thoughts. Alternatively, use #ScratchEurope on Twitter to join in the conversation with the conference attendees online.

Enjoy!
