RE: https://noc.social/@cloudflare/117411089839814724
So RIP Deno… They are stopping work on the runtime over the next 12 months.
I was hoping that we could some day have a Node.js alternative with a more modern interface/tooling, but with this and Bun now being part of Anthropic and vibe-(re)coded to the extreme, it does not seem it will happen.
… and I was quite right to be doubtful of the longevity of those 2 at the start, they both raised money and I could not see how they could continue to exists long-term and keep their investors happy.

we are working on block list synchronization, should be in our next release. But I am not sure it would help with this specific attack.

we want to make changes to tjis, but that will require a lot of work and will come in a future version. 5.0 does not change things at ActivityPub level. We started some internal discussions are are still trying to figure out what to build here exactly, and how it can work at scale.
We will communicate around this when we ourselves know more.

I appreciate the feedback and the concerns here, but I want to point our that those changes are not for the sake of changing.
Our designer (and the various platform developers) are trying to solve many of the problems existing with those interface, while making space for some new features. All of this is deeply thought and discussed (internally, not sure how we could be more public on this) and designed in Figma (for all platforms) before implementation. Then changed if wrong.

In the past month, we started getting a few new accounts created on @npub1ypf…53gr every day, with valid email addresses (but not under the attacker control? confirmation emails are never clicked), random 15 letter usernames from residential IPs all over the world.
After checking a few online RBLs, I started using https://cleantalk.org/, checking the user IP on registration, and it flagged all of them. I did not knew this service before, but it seems both cheap and with good real time data?

As the end of year approaches, we spent some time to rework the Wrapstodon feature that we first tried last year.
It now collects your yearly data on-demand, does not require admins to enable anything (so it will be available to everyone in December 2026) and you get a nice shareable URL with your yearly summary!
Admins on nightly releases can enable it using the "wrapstodon" feature flag. It has been enabled on mastodon.online and mastodon.social

Three years ago, I decided to quit Twitter and install a Mastodon server to see if it can replace it for me. It worked better than expected and I discoered so many new amazing people along the way.
I would also never have imagined that I could end up recruiting and leading the team building it!
What an adventure, and we are only getting started ✨

Now, onwards to 4.6!

After many interviews with such organisations, the main roadblocks for them to join the Fediverse are:
- understanding what it is
- figure out their strategy (number of accounts, do they want their own server, define related policies…)
- figure out with their IT department if they want to host it (and if yet, how to do so), or delegate the technical parts to a 3rd party
- be able to open support tickets and know they will get an answer.
Now we can provide all of that 🎉

After a lot of work and discussions, I am very happy that we are finally announcing our hosting and support offerings to help institutions (cities, government, universities, corporations, non-profits…) get on Mastodon and into the Fediverse.
It will help the Mastodon organisation become more sustainable in the long run, but also provide an easy (easier?) path for those entities to come onboard and embrace open social media.

thanks! Most of those require very significant change to ActivityPub, and we do not have the resources for such a complex task right now.
We are considering something to copy a part of your posts when you move your account, but this also create challenges (you loose your interactions obviously, private posts can’t be moved, and it provides a very easy path to load large volume bad content into an instance at once, so it would need to involve moderation checks)

2025-09-18 19:39:03 UTC

Hey Misty! A few questions on this:
- do you expect to be able to migrate your account if your original server disappears before you can do it?
- do you expect your content to be migrated (= keep it's interactions, replies…), or to be copied over as brand new, backdated, posts?
- do you expect to migrate non-public posts?

For Mastodon API developers: there is no documentation (yet) for the APIs around composing quote posts, but this will come soon.
We added documentation for displaying quote posts (https://docs.joinmastodon.org/entities/Status/#quote), which is already supported in Mastodon 4.4 and we encourage you to support it in your clients as this will soon be available to all users.

This is built on FEP-044f (Consent-respecting quote posts, https://codeberg.org/fediverse/fep/src/branch/main/fep/044f/fep-044f.md), which requires the quoted account to provide a stamp proving that they approved the quote.
If there is no such stamp (or it has been invalidated), then Mastodon (and other software supporting the FEP) will not display the quote.
If the quoted account does not support the FEP, no stamps will be issued, and the quote will not be displayed either, only the link (as before).

And now thanks to @npub19td…g68x I can show you how the retractation works:
- you get a notification when someone quotes you
- on their post, you have a new menu to remove their quote of your post
- you confirm, and your quote is removed and shown as having been retracted
- the quote is no longer displayed on the original post

I do not know a lot about #golang, but I heard that some people here do, so…
I have a service where I would like users to write simple functions (take some input, return a result) in a script language, stored in the database, that is secure (isolated execution and such) and performant. They need to be able to call arbitrary simple functions (string argument, boolean result) that the software exposes to them, and have basic control flow.
What would you use?

We discussed "partial quotes" when working on quote posts, and decided not to explore this because you could easily change the text of what you are quoting to make it misleading but still attributed to the original author. Also it would probably have been good to have this discussion when we asked for comments, now we are deep into implementation and did not get much feedback when asked for it :(

Ivory's quotes are not proper quote posts, but more of a rich preview when a post contains "RE: <status url>”
We are implementing quote posts with full control for the user (choose if you want to be quoted, retract a previous quote…) which requires proper server and client support (see https://blog.joinmastodon.org/2025/02/bringing-quote-posts-to-mastodon/)

Displaying quote posts will be in Mastodon 4.4.0, which we plan to release the first week of July (and is already deployed on mastodon.social).
Authoring quote posts will be in Mastodon 4.5, which will be released as soon as we finished this feature, probably at the end of summer. We are 70% done on quote posts and the hardest part is done (figuring out the protocol details to implement them in the Fediverse while giving control to users), now we "simply" need to finish the code

Yes this is very complex (and not specific to Mastodon, most if not all AP software suffer from it). We are very happy that a contributor offered to solve this, and are doing what we can to review their work and guide them so it is done with all the possible problems in mind.
We are still afraid that enabling this will create *a lot* of instance-to-instance trafic, but we will need to test it to see if it is too much.

You need to store/cache it on your own server so you dont create too much trafic for the remote server (which might not support the Mastodon API, so you cant really load directly from it with the app), plus you need to take care of blocks, post visibility & such. Then you need to figure out when to refresh the data, and how to handle long multi-level threads (that can span many instances).

yes, your server did. Not your app. Your device IP address (plus user agent & such) has not been disclosed to the remote server

because your app should not make requests to another server than your instance, for privacy reasons. And it won’t work on the web.
There is work in progress to have the server fetch all the replies, which is complex and have some potential performance / scalability issues. The first PR for this is https://github.com/mastodon/mastodon/pull/32615

PDQ is something that Meta has been pushing, but from the information I got, you want PhotoDNA, and it's algorithm is closed source (and under NDA).
I am not saying that the current situation is ideal (even if from our experience CSAM on well-moderated Mastodon servers is very infrequent) but mandating every website with UGC to do content scanning is the death of 99% of them. And the "free quotas" that you mentioned do not help at all except for the tiniest sites.

We processed 4.6M images on mastodon.social in the last month. My small instance with 15 active users processed 50k of them. There is no way to scan this without increasing the costs greatly using a 3rd party service. And you can not do it yourself because the CSAM databases are all under NDAs and require a lot of legal agreements to even start have access to the algorithm (which is very closed source)

their issues are legal, not technical. They hinted at it many times. This is also why they have not launched federation in the EU, they are very scared of another billion fine by regulators, so they ask for every little step to be explicitely approved before launching

thats on the roadmap, but the composer is tucked in a very small place right now. I want this badly as well, once we change the general layout so the composer gets more room it will be there

What you describe is what we want to build, and what has the issue I outlined above.
Claire, the GlitchSOC maintainer, is part of the Mastodon team, and she herself says that we should not re-use what Glitch does because it has issues.

This is on the roadmap, but it requires a complete replacement of the status parser, which is a complex endeavour with security & performance impacts. @npub1jcp…927t started experimenting on the topic but we did not find a good way yet.

Very good article about decentralisation, federation, Bluesky, ATProto (and ActivityPub) from @npub1urx…v0z4
https://dustycloud.org/blog/how-decentralized-is-bluesky/
Lot of nuance, deep knowledge and interesting thoughts.

I started playing with DragonflyDB to replace Redis as the app data storage for a Mastodon instance. Redis used 22 GB of memory, DragonflyDB uses 8.5 GB.
That's very impressive, probably in part because Mastodon uses a lot of sorted sets (for timelines) and Dragonfly stores those in a much more efficient data structure, resulting in a lot less overhead (see https://www.dragonflydb.io/blog/dragonfly-new-sorted-set).
Additional bonus: they provide a K8s operator, with built-in HA

Yes it is, and comes from multiple factors. One being the resources, Bluesky has at least 10x our resources, they have been able to recruit a top notch team, do marketing, comms and overall execute very well. I am personally doing my best to get things moving with whatever means I have, and I like to think that this shows real results (for example the projects mentioned above, as well as tripling the engineering team over the last year)

Well, this is completely not true. We (the Mastodon project) are publicly working on https://www.fediscovery.org thanks to a grant from the NGI program, with the goal to solve the (very hard) discovery/search problem in the Fediverse, in a privacy-compliant way.
Quote Posts are also in progress, well specified so the other Fediverse software can implement them and with a lot of controls to respect users choice and privacy. We publish monthly blog posts with our progress

2024-11-08 18:41:47 UTC

Today is my 2 year Mastodon anniversary! After decided to stop using Twitter I created my instance, invited a few friends and started discovering the Fediverse.
Then I tried to help where I saw that my skills could be needed and got hired to rework the project & mastodon.social infrastructures, then moved to a wider engineering role and here I am, 2 years later, working tirelessly to ensure that our beloved software and network thrive.
Long live the Fedivers!

Please open a GitHub issue about this, this might be a valid use-case where we could allow additional hosts there.

we are working on many of those issues, but they are complex, require specific knowledge and so far the Mastodon backend team is only 2 people. Things improve slowly but more resources are needed to go faster.

It helps with some actors, but it is not an issue with many others, including the ones that use captcha-busting software (there are now even “dark" SAAS for this), or for human-generated spam using content farms (we see a lot of those in some countries like Nigeria and Vietnam)

Another consideration: new installations should not allow open registrations by default. This should be a setting that the administrator needs to opt into, and this is a good place to inform them that open registration instances require moderation resources.
In Mastodon, we display a warning when the admin chooses this option. Mastodon also support requiring moderator/admin approval for new sign ups, which helps a lot in preventing automated registrations.

2024-10-17 20:44:49 UTC

I would encourage every Fediverse software project to implement a “dead-man switch" on registrations: if nobody with moderator permissions has been active in the last week, then disable new account creation.
The Fediverse has a significant number of abandoned instances that are used by bad actors to create accounts and send spam.
We implemented this in Mastodon (https://github.com/mastodon/mastodon/pull/29318) and it has been highly effective.

Mastodon supports the SWF foundation. They call us partners because of this support at launch I guess. I have no idea what relationship they have with Meta. And there is no relationship between Mastodon and Meta.
Similarly, Meta is a W3C member, Mastodon participates to some W3C meetings about ActivityPub.

2024-10-10 15:09:41 UTC

Yes, we are a partner / member / supporter / … of the SocialWebFoundation, as I said above, because we think such an organisation is needed for the Fediverse to grow. We are not involved in the Foundation creation, or it's management, neither we have partnered with Meta about anything.

2024-10-10 08:29:17 UTC

Mastodon did not partner with anyone. We support the SWF because we feel this is really needed for the Fediverse to move forward. Meta might think the same, but there is no such partnership (or any other kind of relationship)

After updating the Mastodon iOS app to build with XCode 16, we are noticing some very weird data corruption, but only in Release configuration. We suspect this is some data corruption in one of our dependencies caused by some compiler optimisation, but so far we have not really found out the cause.
iOS dev friends, does this ring a bell?

We released Mastodon 4.3 today, packed with a lot of awesome features: https://blog.joinmastodon.org/2024/10/mastodon-4.3/
I want to thank [@Claire](https://social.sitedethib.com/@Claire ), @npub1vl7…f6g0, [@dave](https://upp2.com/@dave ) for their hard work on the code, as well as [@samhenrigold](https://hachyderm.io/@samhenrigold ) for the design. Also a lot of thanks to our regular contributors, including [@matt](https://cyber.digital-cache.cloud/@matt ) and [@thisismissem](https://hachyderm.io/@thisismissem )
Now let's focus on 4.4! We have a lot of exiting things to work on, we will do our best to release it before September 2025 😅

As this worked for the Internet Archive, let’s try another one:
I am looking first an engineering contact at Youtube to troubleshoot the issue with them no longer returning metadata when Mastodon tries to fetch the preview for a video. It comes from their side and something changed a few weeks ago, and I would like to see how this can be fixed.

we try to do our best regarding accessibility when working on frontend code. But nobody in the team is an accessibility expert, and we do not get many contributions on this topic. If some people want to help this will be welcome!
I would also not rely on automated audits for this, thats a complex topic. We got a few offers for accessibility audits, but then the issue becomes fixing the issues, and the core team wont be able to do it unfortunately

good summary! On the Mastodon side we would like to improve rendering of non-Note content, as well as long form content (like display it in a modal with more formatting? Or embedding all iframe with a special view built for embedding?).

Question for #ActivityPub implementors: has there been any research on how to best handle deletions (accounts and/or posts)?
At the moment, the best (and only?) way to know that an account deletion has been federated everywhere is to notify any known inbox / instance, for every account deletion.
This is very wasteful and not efficient, are there any alternatives? Has anyone worked on this?

“this would be much easier if we were not federated" is probably said at least once a week in our team chat :D

This is not formalised right now, and there is no documented process for this (yet), mostly because we want to first see if this is viable (and that it will probably overwhelm the current team tbh), but for example @npub1ecs…u4wq is doing it, and she has been able to do significant improvements to some parts of the code and those have been merged.
On the other side, others reached out, then disappeared after realising the real amount of work needed for what they wanted to do
