What it does

Canary Checker, an open source, kubernetes native health check platform that provides a unified view of health across the entire stack with 35+ different check types, scripting and prometheus support all built-in.

Kubernetes Native Health Check Platform

Aggregate alerts, run synthetic checks / tests against your services and infrastructure. Generate synthetic traffic, run queries against various datasources, or even run full integration test suites to verify the health of your services and infrastructure. Consolidate alerts across your monitoring stack and create alerts from non-traditional sources like SQL, NoSQL and CI/CD pipelines. Canary checker is a single binary with most checks bundled and not requiring an external installation. Canaries are regular Kubernetes Custom Resource Definitions with conformant status conditions, making it suitable to use as Flux, ArgoCD or Helm health check. Export custom metrics from any check, replacing…from canarychecker.io

Just a minimum effort, out-of-the box, highly contextualized and interactive experience so you and your team can focus on shipping! We basically scan your cluster resources, build usable abstractions on top of all the kubernetes craziness, identify monitor your…

    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…

  • Hi HN! I’m proud to share that we have built a real 3rd party iMessage client for Android. We did it by reverse engineering the iMessage protocol and encryption system. It's available to download today (no waitlist): https://play.google.com/store/apps/details?id=com.beeper.ima and there's a technical writeup here: https://blog.beeper.com/p/how-beeper-mini-works. Unlike every other attempt to build an iMessage app for Android (including our first gen app), Beeper Mini does not use a Mac server relay in the cloud. The app connects directly to Apple…

  • Hey! I made Heynote entirely for my own use case. For many years, I always had an Emacs instance running with the scratch buffer open, even long after I had abandoned Emacs as my programming editor in favor of more recent IDE:s. The simplicity of having just one big scratch buffer appeals to me, but I still want to separate the different things I jot down somehow (without using tabs or similar). Previously, my solution was to insert a bunch of blank lines between the notes, but hitting C-A would still select the entire buffer. That's why I came up with the concept of "blocks", which turned…
