  • Launch of the European Social Association

    SWF is glad to support European.social getting off the ground in Berlin today. This new association brings together Fediverse and other open protocol communities to build real digital autonomy for European governments, companies, organisations and individuals. Open Source and open standards aren’t uniquely European, of course. Everyone around the planet deserves to exercise their autonomy…

  • FOSDEM 2027 Dev Room Application Is In

    One thing people have asked me over the last month is whether #SWF will be organising the Social Web Devroom at #FOSDEM2027 . The answer is: fingers crossed! We submitted the application to manage the devroom ahead of the October 4 deadline. We haven’t heard back yet; the announcements are scheduled for October 20, about…

  • Evan Prodromou on “Search Engine”

    A few months back, we posted about the new Fediverse instance called “the Forkiverse“. This is a Mastodon instance started by the hosts of the Search Engine podcast and the Hard Fork podcast. The site has picked up tens of thousands of users, with a distinctive local culture, and is a nice part of the…

  • Internationalized Webfinger Handles in ActivityPub

    ActivityPub software usually (but not always!) uses a handle format defined by RFC 7033, Webfinger, which looks like username@domain.example. There’s a ActivityPub and Webfinger report from the Social Web Community Group that details how this interaction works. All parts of this handle format can include non-ASCII Unicode characters, like accented Latin, Chinese, Arabic, or Hindi…

  • webfinger package for NodeJS

    About 14 years ago, I created a webfinger package for NodeJS. At the time, NodeJS was only a few years old. I had created pump.io as a new social networking engine and the successor to StatusNet. I needed a client for webfinger lookup — the process of converting a user@domain.tld handle to a API endpoint…

  • Static ActivityPub Publishing

    One of the requests I (Evan) have heard often over the years about ActivityPub is to make publishing on the Fediverse as easy as publishing with RSS. To make an RSS feed for a person or a site, a publisher provides, dynamically or even statically, a single file, with a simple format, and makes it…
