A/B Testing Backend Using AWS Lambda and Redis HyperLogLog

In plain words

Gimel is an A/B testing backend built on AWS Lambda and Redis HyperLogLog that allows developers to run their own testing infrastructure. It's designed for teams that want to manage A/B experiments without relying on third-party services. The system uses HyperLogLog for efficient cardinality estimation and Lambda for serverless computing, making it a self-hosted alternative for experiment tracking and analysis.

  Development teams often struggle with using multiple tools like Postman and Swagger for API design, development, and testing. This fragmented approach leads to outdated API specs and chaotic collaboration. So we built Apidog: a single, unified API platform for team collaboration. It has a beautiful interface that makes it easy to create API spec, generate request data from API spec, validate responses, create mock data, orchestrate test scenarios, and publish API documentation. Apidog = Postman + Swagger + Mock + JMeter.

  Hi 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…
