Thanks all for listening to my talk about at 2026 today! Here's my deck for the talk: Fedify: Building ActivityPub servers without the pain.

Fedify: Building ActivityPub servers without the pain - Slidev

"Implementing ActivityPub looks simple at first—it's just JSON over HTTP,\nright? Then you hit JSON-LD context resolution. Then HTTP Signature\nverification fails on Mastodon but works on Misskey. Then you realize\nthe spec spans hundreds of pages across W3C documents and [FEPs] (Fediverse\nEnhancement Proposals), and every implementation interprets them differently.\n\nI went through this pain building [Hollo], a single-user microblogging server.\nHalfway through, I realized I was building a framework instead of an app.\nSo I extracted that framework and called it Fedify.\n\n[Fedify] is an opinionated ActivityPub framework for TypeScript. It handles\nthe protocol plumbing so you can focus on your application logic.\n\nIn this talk, I'll cover:\n\n - *Type-safe vocabulary:* The Activity Vocabulary spec is loosely defined,\n but Fedify maps it to strict TypeScript types. Your IDE knows that\n `Note.content` is a `LanguageString`, and calling\n `await create.getActor()` returns an `Actor` object.\n No more guessing at property shapes.\n\n - *Comprehensive signature support:* Fedify implements four authentication\n mechanisms—HTTP Signatures (draft-cavage), HTTP Message Signatures (RFC\n 9421), Linked Data Signatures, and Object Integrity Proofs (FEP-8b32).\n For HTTP Signatures, it uses [double-knocking]: trying RFC 9421 first,\n falling back to draft-cavage if rejected, and remembering the preference.\n This kind of interoperability work is exactly what you shouldn't have to\n do yourself.\n\n - *Framework-agnostic design:* Fedify works as middleware for Hono, Express,\n Fastify, Next.js, or any framework that speaks `Request`/`Response`.\n Bring your own database, ORM, and auth—Fedify only needs a key–value store\n for caching.\n\n - *CLI toolchain:* The `fedify inbox` command spins up an ephemeral server\n to receive and inspect activities. `fedify lookup` fetches any ActivityPub\n object by URL or fediverse handle—including from servers that require\n [authorized fetch]. No need to create throwaway accounts on production\n instances.\n\nI'll also share production stories: [Ghost chose Fedify] for federating their\npublishing platform rather than implementing the protocol themselves. Hollo\ndemonstrates single-user microblogging with full Mastodon API compatibility.\n[Hackers' Pub] shows how a developer community can integrate with\nthe fediverse.\n\nWhether you're building a new federated service or adding ActivityPub to\nan existing app, this talk will show you how Fedify turns months of protocol\nwrangling into days of actual development.\n\n[FEPs]: https://w3id.org/fep/\n[Hollo]: https://docs.hollo.social/\n[Fedify]: https://fedify.dev/\n[double-knocking]: https://swicg.github.io/activitypub-http-signature/#how-to-upgrade-supported-versions\n[authorized fetch]: https://swicg.github.io/activitypub-http-signature/#authorized-fetch\n[Ghost chose Fedify]: https://activitypub.ghost.org/day-4/\n[Hackers' Pub]: https://hackers.pub/\n"

The new UNBRK HEX boards have arrived! An improved version of the UNBRK, this ultra-compact prototyping board for QFP48/64/100/144 MCUs has wider trace geometry for better low-power performance, provisions for header pins, and an improved, unique 0201 prototyping grid to experiment with components reclaimed from . released under the CERN-OHL-S and supported by @nlnet and @NGIZeroNGI Zero open source funding, you can find its repository at repo.unbina.re/unbinare/UNBRK_

Two UNBRK HEX prototyping boards are shown, One demonstrates the topside of the board with a footprint that accommodates QFP48, QFP64, QFP100 and QFP144 MCUs and four rows of breakout pads. The other demonstrates the backside of the UNBRK HEX, with its unique 0201 prototyping grid.

いまどき1/4センサーのウルトラワイド？需要の少ない超広角が載っているだけマシということなのか

NothingPhone 3a、カメラレビュー - 50mmレンズ搭載という英断｜ふぁ８ひ

こんにちは。 NothingPhone3aを購入したのでカメラについて作例を交えながら詳しくレビューしていきます。 ちなみにRakutenMobileへのMNPで2.5万円で購入しました。 好みにより、望遠ばかりです。ごめんね 広角 - 24mm Samsung ISOCELL GN9　50MP　f/1.88　1/1.56　OIS ※Nothing向けのカスタムされたGN9らしい？ まあまあまともなセンサーサイズです。大型センサーという程ではないですが、困ることはないでしょう。当たり前ですがノイズ耐性は低めです。 多用するであろう35mmクロップズームでも写りはよく、常用で
