Show HN: Peeng – like Pingdom, but the other way around and simpler
Hey folks! Shahar and Tal from Keep (<a href="https://www.keephq.dev">https://www.keephq.dev</a>) here!<p>For the last few weeks we’ve been building Peeng and can now share our beta with you: <a href="https://www.peeng.sh" rel="nofollow noreferrer">https://www.peeng.sh</a>. 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.<p>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!<p>Quick demo: <a href="https://youtu.be/ZX5mrnMRCwU" rel="nofollow noreferrer">https://youtu.be/ZX5mrnMRCwU</a><p>Why we built this:<p>- We needed an easy way to let Keep (<a href="https://github.com/keephq/keep">https://github.com/keephq/keep</a>) 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<p>The beta version lets you:<p>- 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<p>What’s next:<p>- 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”: “<a href="https://..”" rel="nofollow noreferrer">https://xn--ivg</a>, “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)<p>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 :)

Show HN: Stemformulas.com
During my (ongoing) engineering degree, I've often looked up formulas and been frustrated at the lack of reliable results. Some formulas (usually the easy ones) get their own blurb on Google results, while others are a few clicks away, or are most easily accessed by looking at random university slides on Google images.<p>It felt like, in this day and age, there should be a site that serves the small but noble purpose of being a source of truth for formulas, while leveraging modern website technology to provide a fast and user-friendly experience.<p>So, I made stemformulas.com (with some friends)! It's a really simple website, basically just collection of formulas with a search bar. The formulas are displayed in LaTeX, they're double checked by me against sources that I link for further reading, and I write out all the variable definitions for each one. A feature I recently added was the ability to copy the LaTeX on any formula page (e.g. go to <a href="https://stemformulas.com/formulas/schrodingers-equation/" rel="nofollow noreferrer">https://stemformulas.com/formulas/schrodingers-equation/</a> and click on any LaTeX). LLMs aren't great at getting complex LaTeX right yet, so this felt like a nice value add for users.<p>I've been using this site as basically just a personal hashmap of formulas, but I think it has the potential to help others as well, so I'm hoping to get feedback, formula suggestions, and maybe even some contributors with this post.<p>If you're interested, the source code for the project is available on GitHub at: <a href="https://github.com/stemformulas/stemformulas.github.io">https://github.com/stemformulas/stemformulas.github.io</a><p>About page: <a href="https://stemformulas.com/about/" rel="nofollow noreferrer">https://stemformulas.com/about/</a><p>Thank you all!

Show HN: Sociables: The community platform for content creators and niches
Hey HN. We've been working on a community platform/Reddit alternative with a focus on building a place for people to create communities instead of just buckets of posts. We want communities to feel like a place where you want to hang out instead of just scroll.<p>At a high level, our platform is like a Reddit/Discord/Patreon hybrid. We took all of the best features from each of those platforms and combined them under one umbrella.<p>Here's a list of the core features of each community:<p>1. Customizable discussion boards: Community owners can set up threaded discussion boards for different topics related to their niche. For example, if a user creates a community for a niche like "Sports", they can create different discussion boards for subcategories like "Soccer", "Football", “Hockey”, and "Golf". This is different from Reddit, where you only have a singular discussion board per community. All the posts within these discussion boards are crawlable by search engines, meaning they will appear in search results.<p>2. Voice rooms: Community owners can set up Discord-style voice chat rooms where users can seamlessly jump between different rooms to communicate verbally.<p>3. Real-time text chatroom: We modelled the chat after Twitch so communities can have a form of instant messaging-style communication.<p>4. Synchronized YouTube/Vimeo player: Community owners can create a playlist of YouTube/Vimeo video embeds. Each community has a media player that cycles through the playlist and synchronizes the playback, so people within the community can watch the same video at the same time.<p>5. Baked-in monetization: Community owners can offer customizable tiered monthly membership plans that allow members to financially support them. Owners can also link their PayPal accounts to receive donations. Users can purchase post bumps within the boards and comment awards, and the revenue is shared with the community owner. (Note: Tiered memberships and paying to bump posts/comment awards are in development. Communities can currently only offer a singular membership tier).<p>6. Link-in-bio page: Each community has a link-in-bio style page where community owners can display a list of links related to their community. Posts from the community also appear on this page along with buttons to monetarily support the owner. This page is meant to act as the “cover” page of the community.<p>7. Moderation tooling: Communities can set up custom user roles and assign different permissions within the community to these roles. You can assign permissions such as being able to move posts between boards, remove posts/comments and more. (Note: Our moderation tooling is currently in development. We are exploring integrating AI to automatically scan and flag posts that the moderators should review).

Show HN: PikaTorrent, a modern, multi-platform, open source BitTorrent app
I find existing BitTorrent clients offer a rather old user interface, and it's hard to set up remote access, involving setting up a web server, a TLS certificate, domain name, configuring the router, etc...<p>PikaTorrent tries to offer a modern and easy UI. It is available on desktop (Linux & Windows for now), mobile (Android for now), as CLI as an npm package, and even on the web (as a frontend for remote control).<p>Thanks to WebRTC, one can link the mobile or web app with the desktop or CLI app. This way, it's possible to remotely manage torrents securely and without any complicated setup.<p>From a technical point of view, the app is using Expo and Tamagui to target the web, desktop, and mobile (native), meanwhile libtransmission is used as the torrent engine. So we should expect the same level of performance as the Transmission client.<p>PikaTorrent is open source, and I just released v0.3.0 to let potential users try it out and contribute to the bug/features list on GitHub: <a href="https://github.com/G-Ray/pikatorrent">https://github.com/G-Ray/pikatorrent</a>.
Thank you for your feedback.
