A GitHub Issue Title Compromised 4,000 Developer Machines A prompt injection in a GitHub issue triggered a chain reaction that ended with 4,000 developers getting OpenClaw installed without consent. The attack composes well-understood vulnerabilities into something new: one AI tool bootstrapping another.

This case shows how Open Source will die. With anyone just being able to pipe existing code and tests through an LLM and claiming that to be "clean room" (which is hogwash) no licensing can protect your work from being accumulated and monetized by anyone. The commons are actively being shredded […]

@jerry I foresee a 25% to 50% price increase in the next 2 years for everything requiring hardware, including servers, cloud but also laptops and phones. This will have a *huge* impact.

@jerry Be ready for all providers to announce some in the coming weeks, the hardware world is on fire right now thanks to OpenAI and their shenanigans to kill their competitors (and the AI bubble overall).
OVH announced a 10-15% increase as well.

Our technical direction Hello everyone! I’m Renaud, and I’m the Technical Director at Mastodon. I’ve also been the technical lead for delivering Mastodon releases for several years now. This post is co-written with Imani, our lead product designer. Mastodon continues to grow as more people seek alternatives to centralised social media and closed social networks. Today, we’re sharing our vision for making the Fediverse more accessible, diverse, and empowering for everyone—from first-time users to established creators. At its core, Mastodon remains a microblogging, or short form text app. We’re building an app that enables anyone to connect with their friends, and share their thoughts and creativity. We are part of an ecosystem of interconnected social apps known as the Fediverse - built on common standards and protocols, a space where you can choose the apps and communities that are the right fit for how you want to express yourself, and participate how and where you are most comfortable. Over the past 18 months, we’ve focused on growing our core development team and improving our processes to set us up for this phase of the project. We’ve gone from having one or two full-stack developers, to a broader team with expertise and experience across backend, web, and mobile apps, working with a dedicated designer who helps us to think deeply about how people encounter and use the social web. You’ve seen us increase the rate of updates over the past eighteen months - three major new versions (4.3, 4.4 and 4.5), each with headline new features that the community has been waiting for: improved discovery; better onboarding; list management upgrades; new tools for server owners; and, of course, Quote Posts! We’re far from done, and we plan to continue to deliver regular updates. It is important to understand that Mastodon is vital infrastructure for many, so we will also continue to spend a large proportion of our time on ensuring that the platform remains safe, stable and secure. This is a key reason why we take our time when it comes to evaluating new features. ## The broader roadmap We recently reworked our roadmap, to make it more specific about what we are working on in the immediate future (three to six months). The roadmap on our site represents what we’re directly building in the current and following release cycles: we deliberately keep it focused, and want to avoid committing to add functionality when we may not yet be ready to support it. As we think about our plans, we recognise that we are also part of the broader Fediverse. We make an effort to implement features in an open and interoperable manner, creating new specifications when needed. Recent examples include Quote Posts, Collections, and the Fediverse Auxiliary Service Provider specification - we’re excited to see other people build new implementations. It’s also useful to provide a longer-term view of where we are going, so with that in mind, here’s a broader view of what we’re planning to build over the next 1-2 years. ### A social web for everyone A thriving Mastodon ecosystem is one where anyone can participate, regardless of technical knowledge. We’re redesigning core parts of the experience to make this a reality: a streamlined sign-up flow that explains server choice without overwhelming newcomers, improved search and discovery tools to help you find communities and conversations, and clearer navigation throughout the app. ### Promoting indie servers Right now, too many newcomers default to the largest servers. We want to change that - because Mastodon is best when communities are spread across many independent servers, each with its own character and focus. We’ll be shipping new admin tools to help independent server operators manage moderation and maintenance more easily, like a feature to use external blocklists, extensible ways to set up content scanning to detect illegal content or spam, and ways to reduce your media storage usage by delegating serving remote posts media files from a trusted third party. We’ll also be redesigning server discovery to showcase the diversity of communities available. You’ll hear more about this from Hannah, our Community Director, in tomorrow’s post. ### A decentralised platform for content creators Public figures, journalists, and institutions are looking for alternatives to mainstream platforms – and we want Mastodon to be their first choice. We’re introducing features designed specifically for creators: a redesigned profile view that better showcases their work, and an enhanced compose experience. For organisations like public institutions, we’re working on a new email notification option that allows people to follow their updates even if those people don’t have a Mastodon account yet. This means creators can reach their audiences wherever they are – whether they’re active in the Fediverse or still exploring their options. Our goal is to give audiences and creators a way to connect on their own terms, free from algorithmic manipulation. ### Onward, together These upcoming changes represent our commitment to building a social web that puts people first. Mastodon won’t ever harvest your data or chase engagement metrics. We’re focused on creating spaces where authentic connection can flourish. If you have thoughts on software improvements, send us an email. ### Support Mastodon We’re a small team building software to power the Fediverse. Unlike ad-driven platforms, we operate entirely on donations – and _every contribution matters_. See our donation page for ways to support us. ### Thank you for supporting Mastodon We develop and maintain the free and open source software that powers the social web. There is no capital behind this — we rely entirely on your support. Donate to the project View our sponsors

Ce à quoi nous venons d’assister, tout au long de cette séance de QAG, est un glissement inouï, sans doute historique, vers le fascisme.

Un article du NYT parlant des futurs projets d'Elon Musk d'ouvrir une colonie sur la Lune, faisant suite à ses idées de datacenters dans l'espace. 
L'article ne contient aucune critique du moindre genre, tout juste une allusion sur le fait que le fasciste archimilliardaire n'a jamais expliqué comment il compte s'y prendre, mais évidemment ils ne vont pas non plus aller lui demander. 
On est à la limite du communiqué de presse.

Tom McClellan, un ingénieur en aérospatiale, explique en quelques lignes pourquoi les déclarations de Musk qui veut installer des panneaux solaires sur la Lune n'ont aucun sens : les nuits lunaires durent deux semaines, donc aucune énergie n'y est générée pendant ce temps et il faudra tout stocker, et surtout le delta de températures entre jour / nuit à la surface lunaire risque d'être extrêmement difficile à gérer pour les matériaux.

Trunk & Tidbits, January 2026 ## Intro Welcome to Mastodon’s monthly product and engineering update, looking back at January 2026. ## Events We’ve just published a recap of our visit to FOSDEM 2026. We’ve had feedback that some event updates were a bit buried in the Trunk & Tidbits posts; and, that the results and outcomes of our team presence at events could be made more clear. We’ve heard you, and we’ll be posting these sorts of update in standalone format in the future. ## Releases In the past month, we released the following point versions - these contain bugfixes, and a fix for a security issue, so we strongly recommend that server operators update to a current version. * 4.5.6 * 4.4.13 * 4.3.19 See the associated release notes at the links above for instructions on upgrading, and remember that these processes sometimes require asset recompilation. > Note that all versions of Mastodon from the 4.2.x release branch and below are now out of support, and support for version 4.3.x will end on **May 6, 2026**. Read more about end-of-life dates. ## Backend and Web In January 2026 we reviewed and merged 242 Pull Requests (157 with translation and dependency updates removed) from 16 contributors, 11 of which were from the broader community. Thank you! Progress towards the next major release of Mastodon continues. Here’s what the team has been working on. * ui We’ve been creating new accessible & redesigned form components for use in the editing interfaces for Collections and Profiles * ui Work on the editing UI for the upcoming Collections feature is in progress, so is work on federation of Collections * ui Continued work on the new Profile design: expect some visible changes in the coming weeks, for users running nightly releases * performance Fix a performance issue with the status batch delete SQL query — PR #37469 (by ClearlyClaire) * interface Add new `data-color-scheme` and `data-contract` attributes on `<html>` to let themes easily get the correct color scheme and contrast settings for the user — PR #37477 (by diondiondion) * backend Shortened caching duration for pending quote post approvals, which should help to reduce the number of times a quote is displayed as pending — PR #37570 (by ClearlyClaire) * backend Removed support for ImageMagick, which has been deprecated for the last 2 versions. Mastodon now requires `libvips` — PR #37488 (by mjankowski) * backend Added storage of image descriptions for profile pictures and headers when they come from federation. This does not have any impact in the UI, nor can they be set by Mastodon users for now. — PR #37634 (by ClearlyClaire) ## iOS We started off the year releasing 2026.01, with a few important improvements: * Avoid triggering post actions accidentally while scrolling. * Display Lists in alphabetical order, as on the web. * Improved hashtag statistics layout for longer translations. * Avoid publishing the same post twice by accidentally double tapping the publish button. Most of our iOS work lately has been on the new profile view, which is not yet in released builds. ## Community We spotted some terminal-based Mastodon apps! Have you tried tooi (below)? There’s also mastui, which is an alternative. > Post by @ihabunek@mastodon.social > > View on Mastodon If you’re looking to make yourself more discoverable, then this tool may help you to find ways to do that, by completing more information in your profile. If you’re building with the Mastodon API, please let us know so we can share with the community! ## Thank you, and until next time We believe that it is always important for us to humbly acknowledge the community that supports our work. Thank you - your contributions mean a lot to all of us on the team, and to our mission. We really appreciate your donations. ### Thank you for supporting Mastodon We develop and maintain the free and open source software that powers the social web.

Have you wondered what the team was working on in January? Here's our monthly "Trunk & Tidbits" update from the product and development side. Progress on Collections and more, as we work towards the next major release.

FOSDEM 2026 Recap This year, the Mastodon team returned to FOSDEM for the third time. FOSDEM is an annual gathering of open source developers, held in Brussels. We’re excited to report that the Fediverse is feeling vibrant! FOSDEM has become a central element of EU Open Source Week - a series of events, meetups and workshops that have formed around the conference itself. The range of events makes this trip to Brussels valuable for our team, with opportunities to meet other projects, non-profit organisations, open source foundations, and policymakers. On Friday evening before FOSDEM, a group of around forty Fediverse supporters, builders and enthusiasts got together for a social meetup. This was the first time that several prominent developers across the ActivityPub ecosystem had met in person, and there was an immediate sense of excitement and anticipation! We enjoyed the chance to meet up with both community members, and also developers working on other ActivityPub-related projects. FOSDEM itself runs across Saturday and Sunday. The team had a table with handouts that explained the project; a slideshow covering improvements since last year’s event as well as our roadmap; and some pins and stickers for sale. A few lucky visitors were able to pick up a special _limited-edition_ sticker featuring a “My friends are not for sale” tagline. The Plushtodons also made an appearance, for photo opportunities - unfortunately we were not able to transport any for sale, but folks were able to order new friends directly from the online store. My friends are not for sale stickers - only available at FOSDEM (so far) Reflecting on our third trip to FOSDEM, we’ve been thinking a lot about how things have developed in only three years: * in 2024, Mastodon was the first (and so far, remains the only) Fediverse project to get a stand at the event… and there was no specific conference track for Social Web discussions; * last year, the Social Web track - partly created from the popular demand seen the previous year - was a (packed) half-day affair, with spill over birds of a feather and after hours events; * this year, the track ran throughout the day on Saturday, with _29 speakers_ from countries worldwide, covering both technical and non-technical topics - _and_ there were additional meetups and sessions outside of that! Hannah (Community Director) and Andy (Head of Communications) co-presented a session on Mastodon’s mission, governance and community, and they also announced a forthcoming experiment to extend default server recommendations. > Post by @Mastodon@mastodon.social > > View on Mastodon Overall, this year’s Social Web track highlighted the diversity of projects and discussions in the Fediverse ecosystem. It was also a hub of conversation around the need for greater autonomy in technology choices in Europe. It was a very exciting day. Some speakers at the end of the Social Web track (thank you to @Sturmsucht for being with us throughout the day and for sharing the photo!) On Sunday, our Executive Director Felix was part of a discussion about the Fediverse and the EU’s Digital Services Act. Conversations like these provide opportunities to share our mission, and they help to educate policymakers on the values of the Fediverse. Members of the team also took part in other sessions related to the Fediverse; and the others were kept busy with conversations at our table - although, by Sunday, we’d run out of most of the merchandise items we’d taken along… > Post by @Mastodon@mastodon.social > > View on Mastodon At Mastodon, we value everyone across the community - our fellow developers, people who run Fediverse servers, and the people who use Mastodon and other connected applications every day. We were happy to be back in Brussels for FOSDEM, and we hope to return to continue the important conversations that happen there. Thank you to everyone who visited our table, for their interest and kind words about the project. We’re building a better social web for everyone, and we were happy to see you there! If you’re curious about what you missed, have a look at the recordings from the Social Web track. ### Thank you for supporting Mastodon We develop and maintain the free and open source software that powers the social web.
