According to @tchambers@indieweb.social's My 2026 Open Social Web Predictions: Fedify will power the federation layer for at least one mid-sized social platform (500K+ users) that adds ActivityPub support in 2026. The “build vs. buy” calculation for federation shifts decisively toward “just use Fedify.” We're honored by this recognition and will keep working hard to make #ActivityPub adoption easier for everyone. Thank you, Tim! #Fedify #fediverse #fedidev

@jansenspott @mthie ich will mich nicht aus der Affäre ziehen, aber alles was wir mit dem Plugin machen ist: wir schicken eine Überschrift, eine summary, den content mit inline images und die Images nochmal als attachment. Dadurch kann jedes empfangende Netzwerk entscheiden was es am besten anzeigen. Ich schau mir das aber gerne im neuen Jahr nochmal an. Vielleicht finden wir ja mit den gotosocial devs eine schöne Lösung!

@dontblink grazie a te per il riscontro positivo

If it exposes sockets to the Internet, it should be contained. Not by Docker but by Podman. #rootless @mapache

@jansenspott @herrjemineh @kaffeeringe oh! das muss ich mir gesondert nochmal anschauen!

Translating ActivityPub newly added strings into Italian. The stable release. #ActivityPub #WordPress

@mapache@hachyderm.io it looks amazing! I really wish I could attend.

@atarifrosch @activitypub.blog @about.iftas.org There’s no intention to exclude ClassicPress. Our resources are limited, so we don’t actively test with it, but I’m happy to fix issues when possible... or, even better, merge PRs that resolve them.

@informapirata @fediverso Sulla faccenda hashtag del fediverso vs. tag di WordPress, devo aggiungere una dritta che ho scordato. Il post di ActivityPub funziona così: se dalle impostazioni si setta "automatico", lui di default prende [title] [excerpt] [permalink] [tags] non credo ci sia bisogno di spiegare in modo non-tecnico cosa siano queste variabili. Se, come scritto nel post precedente, io rimuovo il tag dal post (e dall'elenco tags) perché inutile per il resto del sito, questo non mi entra nel post che poi passa nel fediverso una volta pubblicato.Quindi, nel migliore dei casi, si lascia l'excerpt vuoto sostituendolo con uno-due paragrafi seguito da un blocco "altro", o qualunque sistema si voglia usare per il "leggi di più"... Se non trova il riassunto (excerpt) lui prende la prima parte. Che è meglio strutturare con una intro sintetica e gli hashtag, poi c'è anche un flag nelle impostazioni blocco, che te lo fa vedere o meno questo excerpt quando apri il sito.Dopodiché da WordPress -> tags (a seconda del plugin SEO) gli si toglie l'indicizzazione a quel povero tag solitario, e sul sito eventualmente si linka la risorsa esterna più accreditata a quell'evento specifico. Ma io rimango sempre dell'idea comunque di non usare troppi tag, di non perdere nella qualità e organizzazione dei contenuti, per star dietro ai trend che ancora poco e ti mordono le dita dei piedi.

Frequently /me [from DE] thinks about #Datensparsamkeit The officially best [en] explainer is https://martinfowler.com/bliki/Datensparsamkeit.html@mfowler I became a Carteret Islands person once.Looking at my shell neclace.My wish for christmas is that you read it and carefully think about all the things you publish in terms of accessibility but also formats and size.An example:For @clemensg I did the yearly #ActivityPub #Atlas - it comes with millions and millions of geohashed places for OSM, wikidata, official sources and, well openaddresses [.io] They publish primarily in texts with lines of geojson.The whole planet is about 46 GB … … …An exmple:DE in this "format" is about 3.2 GBDE in CSV would be maybe 1.5 GB If we normalize and publish it compressed, it is [incl geohashes] about 800MB. If we now compress the geohashes, expanding it clientside the 3.2 GB becomes 250 MB …Maybe we can't save tons of powerplants like banning bitcoin would.But together we can save lots of energy.#geojson 💣

We're very excited to announce that we're sponsoring Protocols for Publishers - @team - in London.As well as helping support the event, @saskia will be joined by Siddhartha from The Bristol Cable to talk about building a social app for a local community, with their local news publisher.Find out more here: https://protocolsforpublishers.com/london-2026/#ProtocolsForPublishers #ActivityPub #SocialWeb #Fediverse #SocialMedia #Mastodon #Event #London
