OK Fedifriends, I need your help with some complex ActivityPub stuff.

Mastodon won't show a list of followers for @coloursColours Bot

It has an orderedcollection at colours.bots.edent.tel/followe which paginates properly.

The mimetype and JSON are all correct, I think.

You can check out the source code at gitlab.com/edent/activity-bot/

What magical incantation do I need to do to help Mastodon see the details of the account's followers?

Feel free to reply here or on the repo.

Latest in sea trials. An old 12v trolling motor provides propulsion. A pico is always-on and runs the basics, sensors, h-bridges and such.

An RPi4 will be the main autonomy hub to enable detailed mapping and surveys and such. But for now I can just push buttons in and move it around.

I built it almost totally out of scrap and epoxy. What a delightful waste of time! 😜

P. S. Note the crew on the bridge.

Dear Fedi friends,

I'm really proud to share with you a video I made: "Introducing the Fediverse: a New Era of Social Media" https://news.elenarossini.com/fediverse-video/

In this 4-minute video I explain what the #fediverse is to people not familiar with it, mentioning some of its great features and benefits (interoperability, no ads, no surveillance...) and I set it in contrast to the world of Big Tech social platforms. I argue that, with the rise of Big Tech oligarchs and the current political climate, there has never been a better time to join the fediverse.

I hope you will enjoy this video and that you will find it useful (maybe as a tool to introduce your friends, family, colleagues, school administrators, local government officials to it).

The fediverse has truly changed my life, making me a better, more empowered digital citizen. I am endlessly grateful for it, so this is my contribution to the cause ❤️

I am also incredibly thankful for the work of @samaabergSamuel Aaberg and @patel.riyenThe Life of Tarzan who helped me bring my vision to life with their amazing cinematography skills and their assistance throughout the process, providing brilliant feedback to the script / edits from the POV of fedi newbies.

And I was also moved by the generous help of people of the Fediverse who volunteered to translate the script into many foreign languages: @janJan Dytrych🇨🇿🇺🇦 @fritjofFritjof :emacs: :ardour: @erikkempErik Kemp 🇪🇺🟥 @sknob @severin @clabruClaudio @tarcisiosurdiTarcísio Surdi ⁂ :verified_sc: @hongminhee洪 民憙 (Hong Minhee) @danielcasanueva @ainaliJan Ainali @naclyPen

Lastly, I'm thankful for the opportunity I had to premiere the video last week at #FediForum - thank you @j12tJohannes Ernst and @anca

The video is up on my self-hosted PeerTube instance (thank you @yunohostYunoHost :neopossum_box:) and for now it is unlisted as I have no idea how my VPS will hold up. I also included an alternate location in the blog post.

I hope you'll enjoy it! It's been a real labor of love (a month of full time work on it)... I see it as my love letter to the fediverse 💌

Edit/update: THANK YOU for all the people who volunteered to have their avatar show up in the last shot. There were 750+ submissions and only 135 spots - sorry I couldn't include everyone 🥲

Good rule of thumb: don't spend your hard-earned time on any social platforms that do not have end users like @_elenaElena Rossini ⁂ creating videos like this about them. :fediverse: Very worth viewing and sharing:

Dear Fedi friends,

By now you might have seen the post announcing the release of my promotional video for the Fediverse. But in case you have boosts turned off, here we go: news.elenarossini.com/fedivers

I posted about it this morning from my account because I have a 5000 character limit there. And I had so many people to thank for their help. It really takes a village.

Thank you for all the wonderful feedback so far ❤️

„Größte Beweisvernichtung der Steuergeschichte“: Kommen Steuerhinterzieher leichter davon?

Bürokratieabbau ist eines der wichtigsten Vorhaben der neuen Regierung. Doch weil Steuerbelege bald schneller vernichtet werden dürfen, fürchten Experten einen Milliardenschaden für den Staat.

New from 404 Media: Delta, United, American etc don't want you to know they sold your flight data to DHS. The country's airlines sell bulk names and flight itineraries to DHS to be searched without a warrant. Contract tells DHS to not reveal where this data came from 404media.co/airlines-dont-want

Airlines Don't Want You to Know They Sold Your Flight Data to DHS

A contract obtained by 404 Media shows that an airline-owned data broker forbids the feds from revealing it sold them detailed passenger data.

A few weeks back I read on Mastodon that the US Dept of Health and Human Services was getting rid of COVID tests. This is bad for all the reasons, but some enterprising government employee did a program where you could fill out a form and get anywhere from 300-3000 COVID tests (unexpired) sent to your home. I figured why not try? Last week I got seven boxes of COVID tests delivered to my porch. I posted to a local mailing list and I am getting them pointed towards my community. Thanks Mastodon!

My front porch with five bags and two larger boxes which all have people's names written on them in big block letters. The bags contain COVID tests.a bench inside my house with seven large boxes full of COVID tests. They say "intelliswab" on the side of them and are stacked tightly but still take up a lot of room.

iPadOS 26 개발자 베타 하루 써봤는데 제법 괜찮다 맥북 사용성의 80% 정도 따라온 상태에서 터미널이 빠지고 셀룰러 + 터치를 추가한 정도?

물론 아직은 불안정해서 업데이트 권장은 못하겠지만 안정화되고 나면 생산성이 꽤나 좋아질 것 같음

Mistral's first reasoning LLM - Magistral - was released today and is available in two sizes, an open weights (Apache 2) 24B model called Magistral Small and an API/hosted only model called Magistral Medium. My notes here, including running Small locally with Ollama and accessing Medium via my llm-mistral plugin simonwillison.net/2025/Jun/10/

Here's my writeup of , in which I ask the question: is the fediverse making meaningful progress vs. centralized platforms? The post includes @_elenaElena Rossini ⁂'s excellent video and has discussion of @cwebberChristine Lemmer-Webber's presentation, Bounce (by @quillmatiqAnuj Ahooja & @snarfed.orgRyan Barrett), Surf (by @mikeMike McCue & @marciMarci McCue), Channels.org (by @michaelMichael Foster & @newsmastNewsmast Foundation team), & Bandwagon (by @benpateBen Pate 🤘🏻). Thx also @j12tJohannes Ernst & @anca for FediForum. The headline is via Christine: "we can’t succeed without joy." thenewstack.io/bringing-joy-ba

Bringing Joy Back to the Web: Fediverse vs. Centralized Apps

The future is federated, say open web fans. But while new products demoed at FediForum show promise, is it enough to usurp X and Facebook?

WWDC25: macOS Tahoe Breaks Decades of Finder History - 512 Pixels

Something jumped out at me in the macOS Tahoe segment of the WWDC keynote today: the Finder icon is reversed. You can see that in the image below. On the left is macOS Sequoia, and on the right is macOS Tahoe: I know I am going to sound old and fussy, but Apple needs to […]

我和我的祖国
一刻也不能分割
无论我走到哪里
都听人唱它赞歌
我凝视每一座深渊
深渊也凝视着我
袅袅炊烟
小小村落
拿它真没辙

嗯，这样配着王菲的调子，就有嘲讽内味儿了~
