Svix – Open-Source Webhooks Service Written in Rust2022 · github.com · ▲176We are super excited to be open sourcing the Svix webhooks dispatcher! Svix makes it easy to send webhooks. You send your payload to Svix, and Svix takes care of deliverability, retries, security, and more. You can read more about why we built Svix in the original Show HN[0], though the gist is: our customers wanted webhooks to build integrations and workflows around our product, but we weren't willing to commit the engineering time, resources and ongoing maintenance required of a webhook delivery system. Why open source? On a personal level, I've been an open source maintainer and…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hey HN, I've been working on https://pornpen.ai, a site for generating adult images. Please only visit the site if you are 18+ and willing to look at NSFW images. This site is an experiment using newer text-to-image models. I explicitly removed the ability to specify custom text to avoid harmful imagery from being generated. New tags will be added once the prompt-engineering algorithm is fine-tuned further. If the servers are overloaded, take a look at the feed and search pages to look through past results.
