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: Launch VM workloads securely and instantaneously, without VMs Hello HN! We've been working on a new hypervisor https://kwarantine.xyz that can run strongly isolated containers. This is still a WIP, but we wanted to give the community an idea about our approach, its benefits, and various use cases it unlocks. Today, VMs are used to host containers, and make up for the lack of strong security as well as kernel isolation in containers. This work adds this missing security piece in containers. We plan on launching a free private beta soon. Meanwhile, we'd deeply appreciate any feedback, and happy to answer any questions here or on our slack channel. Thanks! April 29, 2021 at 07:50AM
