Recently I dove into the Dutch RVO webservices to get agricultural field data. Dealing with legacy SOAP, GML and PKIO certificates was... an experience. I therefore build a TypeScript package that can act as a connector and handle the heavy lifting and just output a modern GeoJSON (including reprojection to WGS84). I made it open-source at https://github.com/SvenVw/rvo-connector. It's a start as it now only supports requesting fields and not altering fields yet #TypeScript #rvo #Agriculture #netherlands

#BotKit is a #TypeScript framework for building #ActivityPub bots. The difference from typical Mastodon/Misskey bots? Your bot runs as its own independent server—no platform account needed.

This means no character limits, no rate limiting headaches, no API restrictions.

bot.onMention = async (session, message) => {
 await message.reply(text`Hi, ${message.actor}!`);
};

The ActivityPub stuff (federation, HTTP Signatures, delivery queues) is handled by #Fedify under the hood. You just write your bot logic.

Works with both #Deno and #Node.js.

BotKitは、ActivityPubボットを作るためのTypeScriptフレームワークです。既存のMastodon/Misskeyボットとの違いは、ボット自体が独立したサーバーとして動作すること。プラットフォームのアカウントは不要です。

文字数制限もなければ、APIレート制限に悩まされることもありません。

bot.onMention = async (session, message) => {
 await message.reply(text`こんにちは、${message.actor}さん！`);
};

フェデレーション、HTTP Signatures、配送キューといったActivityPub周りの処理はFedifyがすべて引き受けます。ボットのロジックを書くだけです。

DenoでもNode.jsでも動きます。

BotKit은 ActivityPub 봇을 만드는 #TypeScript 프레임워크입니다. 일반적인 Mastodon/Misskey 봇과 다른 점은, 봇 자체가 독립된 서버로 돌아간다는 겁니다. 플랫폼 계정이 필요 없습니다.

글자 수 제한도 없고, API 호출 제한에 시달릴 일도 없습니다.

bot.onMention = async (session, message) => {
 await message.reply(text`안녕하세요, ${message.actor}님!`);
};

연합(federation), HTTP Signatures, 메시지 전달 같은 #ActivityPub 관련 처리는 Fedify가 알아서 해줍니다. 봇 로직만 짜면 되는 거죠.

#Deno 및 #Node.js 둘 다 지원합니다.

I've been playing with Clojure lately. Tonight, I released a Telegram bot that generates a QR code from any string you send to it. A few months ago, I made another QR bot in TypeScript using Zustand/Immer as the backend. In Clojure, there's no need for external libraries: immutability, atoms, and watchers are all built into the language.

#ReleaseTuesday — Earlier today, I published https://thi.ng/arcball, a small new package providing an intuitive click & drag 3D camera view controller which is completely agnostic from any UI/drawing/rendering framework. The library simply provides the (quaternion) maths to translate gesture events into rotations and then computes a view matrix (presumably for WebGL/WebGPU).

The code is ported from the old 2016 Clojure implementation in https://thi.ng/geom-clj, which itself is based on a 1992 paper (link in readme). Behind the scenes it uses https://thi.ng/matrices and https://thi.ng/vectors for various math ops.

There's also a small new example project to show how to use it (mouse & touch events are enabled, but zooming only works via scroll gestures on touchpad or mousewheel):
