Peeng – like Pingdom, but the other way around and simpler
Hey folks! Shahar and Tal from Keep (https://www.keephq.dev) here! For the last few weeks we’ve been building Peeng and can now share our beta with you: https://www.peeng.sh. Peeng is the easiest and quickest “heartbeat” architecture we could think of. Just pick a subdomain (e.g. x.peeng.sh), configure an interval, an endpoint, and a payload, and hit that subdomain every <X (interval) seconds — If you won’t, Peeng will send an HTTP POST request to your configured endpoint. It’s Pingdom/Cronitor/heartbeat.sh free alternative (but the other way around and A LOT…
In plain words
Peeng is a heartbeat monitoring service that works through outbound checks rather than inbound ones. Users configure a subdomain, interval, endpoint, and payload, then ping that subdomain at set intervals. If pinging stops, Peeng sends an HTTP POST request to a configured endpoint. Designed for developers, system administrators, and those in complex networking environments like on-premises setups or Kubernetes clusters, it offers a simpler alternative to services like Pingdom and Cronitor.

Hey folks! Shahar and Tal from Keep (https://www.keephq.dev) here! For the last few weeks we’ve been building Peeng and can now share our beta with you: https://www.peeng.sh. Peeng is the easiest and quickest “heartbeat” architecture we could think of. Just pick a subdomain (e.g. x.peeng.sh), configure an interval, an endpoint, and a payload, and hit that subdomain every <X (interval) seconds — If you won’t, Peeng will send an HTTP POST request to your configured endpoint. It’s Pingdom/Cronitor/heartbeat.sh free alternative (but the other way around and A LOT simpler, with a lot more capabilities), suitable for developers, system administrators, DevOps, and individuals with complex networking situations (think “onprem” or K8s clusters with no inbound). Instead of inbound heartbeat checks — Peeng presents outbound heartbeat checks! Quick demo: https://youtu.be/ZX5mrnMRCwU Why we built this: - We needed an easy way to let Keep (https://github.com/keephq/keep) customers behind closed networks monitor their Keep instance - We needed an easy & quick way to setup monitoring for our cronjobs - We wanted to give people with complex networking situations (e.g. behind a firewall) an easy way to monitor their services/processes The beta version lets you: - Create 5 endpoints for free - Configure the endpoint and the payload to be sent when the subdomain is not hit - See the visits (every HTTP GET request to your subdomain) and requests (every HTTP POST sent to your configured endpoint) - Secret header (x-peeng-secret) that confirms requests are made by you What’s next: - A status page that displays your subdomains and their health together with embeddable status blocks that allow you to display the status of an endpoint in your web page (you can also send query params when sending the GET requests that will be included) - Rest API (for subdomain creation, beats retrieval, etc., imagine curl -X POST peeng.sh/subdomain -H API_KEY —json {”subdomain”: “hn”, “endpoint”: “https://xn--ivg, “payload”: {…}}) - Hierarchy-based subdomains that allow you to create a nested heartbeat solution (i.e. dynamically create a heartbeat subdomain under x.peeng.sh → y.x.peeng.sh, z.x.peeng.sh) This is still very early, so we’d love to hear your feedback and opinions. We’re open to any feature request, so just reach out via Intercom :)

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

I saw this [0] pretty cool thread by user revskill, and wanted a quicker way to search through it, but also to keep them all in one place so I can read them at my leisure whenever I get time. Right now is like 60 lines of Ruby using Nokogiri, but I will certainly look into it further down the line and improve the list. There's a cronjob checking the thread every 12 hours but I will eventually shut that down and it will become static after that. There are some really awesome blogs in there. I really recommend going through the list, it made my day. [0] "Could you share your personal blog…
