일본에서 제가 쓴 Fedify 책 〈실천 Fedify: ActivityPub 마이크로블로그 개발 입문〉(実践Fedify——ActivityPubマイクロブログ開発入門)이 나왔어요! 정식 출판된 책은 처음 써보는데, 그게 한국어가 아니라 일본어라는 게 뭔가 신기하네요…!

お、洪民憙さんの本でてるじゃん。

みんなActivityPubの自力実装で挫折するぐらいなら、この本を買ってFedify組み込んで開発するといいよ。

제가 오픈 소스로 만들고 있던 Fedify 프로젝트가 글로벌 퍼블리싱 플랫폼인 Ghost로부터 펀딩을 받게 되었습니다! 그래서 한동안은 Fedify 일만 하려고 합니다.

**Fedify 2.0.0 is here!**

This is the biggest release in Fedify's history. Here are the highlights:

* **Modular architecture** — The monolithic `@fedify/fedify` package has been broken up into focused, independent packages: `@fedify/vocab`, `@fedify/vocab-runtime`, `@fedify/vocab-tools` […]

We'd like to introduce the #fedify project family—a set of related tools that make building #activitypub applications more accessible:

오픈소스 블로깅 플랫폼 고스트 에서 약 두달 전 ActivityPub 를 지원하기로 결정하면서 페디버스를 수용한다고 발표했는데요.

오늘 Ghost 에서 ActivityPub 를 위한 오픈소스 프레임워크로 Fedify 를 사용하기로 결정한다고 메일이 왔네요.
참고로 Fedify 는 한국인 개발자 홍민희 님께서 만든 오픈소스 입니다. 정말 멋진 일이라고 생각합니다! 👍

This is great - @fedify has launched an @opencollective to help sustain the project. This is a great library and framework that is helping many other projects grow into the #fediverse. Shout-out to @hongminhee! (also to @liaizon for posting about it as well)
