Show HN: Lingle – Voice agent to simulate zoom-based personal language lessonsIn my opinion the best way to learn a language (outside of moving to a different country) is to get a personal tutor and have consistent 1 on 1 lessons. I used Preply or iTalki for this back in the day but had issues with flexibility and pricing.I've been trying to simulate the experiences that I had on those platforms with a voice agent.You can try a demo for free here (or watch a video of me using it on the landing page):https://lingle.ai/tryout/lingle-showcaseRight now the agent can plan a lesson with visuals and a conversation focus, guides the user through the lesson - correcting and explaining things on a whiteboard if necessary, and asks relatively engaging questions. There is also a long term user model that builds over time, that maintains memory of the user's produced vocabulary, grammar, and skills, meant to make each lesson informed by the past and build on the user's knowledge (obviously this is still relatively fragile in practice).The voice agent itself has actually dece


Show HN: OneCamp – Self-Hosted Slack/Asana/Zoom/Notion AlternativeLaunching in 6 days (March 7)!We wanted OneCamp to be a masterclass in modern architecture, so we open-sourced our entire Next.js frontend.Here's the tech stack powering it:1/ Collaboration & CRDTs Custom Node microservice with Hocuspocus + Yjs for real-time Tiptap edits over WebSockets. Redis caching + JSON/HTML transform to Go backend.2/ WebRTC & Real-time AI Self-hosted LiveKit SFU + custom Python agent that pipes audio to Deepgram nova-2, rebases timestamps, and broadcasts live transcripts.3/ Polyglot Persistence Postgres + Dgraph (graph relations) + OpenSearch (full-text search).4/ Observability OpenTelemetry traces/logs to self-hosted HyperDX on ClickHouse.The frontend (Next.js + React) is 100% open source (MIT).

Show HN: Practice where countries are in the worldTLDR: Practice where countries are on the world map https://www.samlearns.org/world-mapHello HN,...I keep making little web apps to practice geography, and since some people here enjoyed the previous version, I thought this one too. It's a simple game loop where you have to either tab or name countries, w/ some varying conditions like zoom levels.Following feedback from last time, I reconsidered almost all of the game systems, fixing quite a few issues (too hard, too easy, too many boring islands, countries recurring often, confusing UX, ...). The stack is ts/vue and geojson, with some python for data crunching; learning algo built on top of FSRS.It's all free, no-ads, no-signup and open source, in case you were wondering.Feedback and ideas welcome!Hope you get something out of this, cheers :)

Show HN: Sel – macOS screen sharing that shows only the windows you pickHi, Aria here.I do a lot of live demos for customers, and I kept being nervous about what else was on my screen: notifications, other clients' windows, a messy desktop. Sharing one window is safer but then I'll be stuck with one window. So I built Sel.First, pick the windows you want to show. Then, they'll be captured via ScreenCaptureKit and composited on a Metal pipeline into one canvas, over a background, and with an optional webcam bubble (and other kinds of overlays). You share that single canvas window in Zoom/Meet/whatever. The rest of the desktop never enters the frame, and you can prepare named "scenes" (demo, code, browser, etc) before the call and switch between them live, with a transition.
