Show HN: Radiopaper – Troll-resistant public conversations Hi HN! We're a bootstrapped team of 4 and have been building Radiopaper for around 16 months alongside other full-time, part-time, and consulting jobs. I wanted to highlight a couple of the unique characteristics of Radiopaper that may not be immediately apparent when browsing https://ift.tt/mTLzuUn * It's possible to interact with Radiopaper entirely by email, and never log-in interactively. The notification emails contain context that explains that if you reply to the email, your message will be published on https://radiopaper.com * The key mechanism that makes Radiopaper different from other social networks, and more resistant to trolling and abuse, is that messages are not published until the counterparty replies or accepts your comment. You can read more about this in our manifesto at https://ift.tt/tnxrevg The technical stack is a Vue/TypeScript app talking to an API backend written in Go, running on Cloud Run, and using Firestore for persistence, Firebase Auth for authentication. Email processing is handled through the Gmail API hooked up to a Cloud Pubsub notification which triggers another Cloud Run service. Outbound emails go through SendGrid. The whole stack "scales-to-zero", and on days that we have a few hundred active users, we're still under the free limits of Firebase Hosting, Cloud Run & Firestore, so this has allowed us to operate for a long time without funding or revenue. Our overall burn rate is around $40/month, mostly from the smattering of other SaaS offerings we use: Sentry, Mixpanel, Github & SendGrid. Dave & I discuss our tech stack in a little more detail in this conversation: https://ift.tt/2DjrLkq The team (myself, daave, davidschaengold, youngnh) will be around to answer any questions! https://ift.tt/mTLzuUn April 30, 2022 at 03:18AM
Show HN: StreetComplete, an OpenStreetMap Editor for Humans StreetComplete is an OpenStreetMap[0] editor directed at people who want to contribute and want to do this using their smartphone, without learning how to edit things[1]. It is available as an Android application. It is intended to be used as one walks, with quests appearing as markers on the map. Selecting a marker allows one to answer a simple question. The answer will be added to the OpenStreetMap database, with app handling selecting objects for editing, transforming answer into OSM tags and making edits. OpenStreetMap account is needed to apply edits, but it is possible to start without it, make some edits and login/register later. Note: I am not the main author, but I am one of the active contributors. Github page is at https://ift.tt/2g8lasH and https://ift.tt/3nR9PzS shows what was recently released.
