Show HN: Cptn.io – open-source integration platform https://bit.ly/3B6FuWu

Show HN: Cptn.io – open-source integration platform Hi, I am Krishna Thota. I am building an open source integration and data platform( https://bit.ly/3B6FwxA ). The product is MIT licensed and the repo is at https://bit.ly/3M6eHQd . I have started on my startup journey an year ago and launched a monitoring platform called DevRaven. Unfortunately the product did not takeoff as expected. That story is for another day. But during the course of building the product, I have built several integrations leveraging MQs and Cloud Functions. While building and deploying Cloud Functions for happy paths is easy, I had to monitor logs for failures, build retry mechanisms or manually process failed events, keep instances running to prevent cold start timeouts. It can also get expensive with charges for MQs, server time for running cloud functions etc and costs can be unpredictable. I thought of building a platform where I can build integrations quickly, have the ability to look at incoming/outgoing events, look at logs, retry any failed events etc. And finally, predictable costs for running the infrastructure. cptn.io provides all these capabilities and more. You can build pipelines to integrate with any cloud services, send data from your backend to data warehouses, listen to web hook events etc. The platform can be integrated into any stack by sending events to HTTP end points. Instead of trying to build a business first or launch an open source product under restrictive licenses, the platform will be available under MIT license so any user or customer can use it. There is no ee folder or complex dual licensing and I am also committing to releasing SSO under MIT. The plan is to offer a managed service in the cloud at a later time, accept sponsors for prioritizing features for enterprise customers and charge for enterprise support. It should take less than 5 minutes to get the platform running on your machine. Welcome any feedback, feature requests, PRs and bug reports. https://bit.ly/3B6FwxA May 8, 2023 at 06:45PM

Show HN: Automatic Domain Verification https://bit.ly/3LFydSt

Show HN: Automatic Domain Verification The Domain Verification protocol stores a DNS TXT record at a DNS name derived from a hashed "verifiable identifier" (email, telephone, DID), enabling anyone that can prove control over the verifiable identifier to prove authority for the domain name, whilst preserving the privacy of the authorised party. Once setup, the record enables automatic domain verification for any service provider. This record could be automatically setup by domain registrars upon domain registration (with registrant opt-in) creating a fast lane for verification with service providers many new small businesses use (eg Google Ads, Facebook, Office365, Dropbox, etc). ===== Quick sidebar: This was originally submitted to HN under the title "Show HN: Make domain verification as easy as verifying an email or phone number" 3 days ago [1]. It was doing really well (#3 on front page) then totally disappeared from front page and went to bottom of page 1 of Show HN. After an email exchange with dang (incredibly helpful as always), he explained that it got flagged with the "overheated discussion detector" and it turned out I caused this by diligently responding to every comment as fast as my fingers would type because I wanted to keep engagement going. Helpfully dang took the flag off it about 12 hours later after our email exchange, but understandably the momentum was lost. So I feel like it kinda got killed, just as it was picking up pace and as the US west coast was waking up. So I am humbly reposting it with a modified description based on the comments of the last post. ===== This is a project I've been working on for a little while and I'm interested in your feedback and point of view. Many of us would have verified a domain name by pasting a string into a DNS TXT record. These methods are currently being discussed and standardised at the IETF [2]. Let's Encrypt's DNS-01 method [3] is probably considered the state of the art. The differences between DNS-01 and Domain Verification protocol are: - DNS-01 requires a new TXT record for each service provider. With Domain Verification Protocol, multiple service providers can use the same record. - Instructions to setup a DNS-01 TXT record are instigated by the service provider, whereas a Domain Verification Protocol record can be setup independently by a user or a domain registrar. They could even pre-populated by a registrar upon domain registration (with registrant opt-in) - There’s no concept of permissions in DNS-01, the act of creating the record gives the user full access for the domain with the service provider. With Domain Verification protocol multiple records can be setup, limited permissions could be setup for different third parties. For example give a marketing agency authentication to claim the domain on social media but nowhere else. I'm still working on licensing but creating these records will always be free. I hope to find service providers that see significant upside in reducing friction for user onboarding that are willing to pay to license it. Worked example: Let's say you want to authenticate the user with the email user@example.com with the domain dvexample.com, these are the steps: a. HASH(user@example.com) -> 4i7ozur385y5nsqoo0mg0mxv6t9333s2rarxrtvlpag1gsk8pg b. Store Domain Verification record at: 4i7ozur385y5nsqoo0mg0mxv6t9333s2rarxrtvlpag1gsk8pg._dv.dvexample.com c. TXT record determines permissions and time limit: @dv=1;d=Example user email;e=2025-01-01;s=[seo;email];h=4i7ozur385y5nsqoo0mg0mxv6t9333s2rarxrtvlpag1gsk8pg Thanks for taking a look, Elliott 1. https://bit.ly/41nLwgh 2. https://bit.ly/3HPPWFC... 3. https://bit.ly/3nHzOPE https://bit.ly/3nyKdgB May 8, 2023 at 06:06PM

Show HN: Play SineRider, a math puzzle game built by teenagers at Hack Club https://bit.ly/3LH0bgw

Show HN: Play SineRider, a math puzzle game built by teenagers at Hack Club Messing with your TI-84 graphing calculator is a rite of passage for every teenager who has ever been bored in a math class. In 2013 I was that teenager, and it gave me an idea for a tiny game about sledding on graphs. This project grew into my white whale, and I spent my twenties trying and failing to finish it alone. I shelved the game when I started working for Hack Club in 2018—until last May, when a few community members took it off the shelf. The project took on a life of its own, and turned into a year of nights and weekends from a global team of 20+ teens in 8+ countries. Today SineRider enters public beta! SineRider is literally an infinite universe of function composition puzzles, each with infinite solutions, that range from welcoming for 9th graders to difficult for even the most serious matlab user. And every day we tweet out a fresh one to be solved with your morning coffee. We hope you enjoy playing SineRider as much as we’ve enjoyed making it. And we’re not done! Mobile support, polar coordinates, and a level editor are all on the roadmap. SineRider is a living project, to be continuously built and maintained as free OSS by the Hack Club community: https://bit.ly/42dM61j The team that built the game will try to be in the comments today between high school classes and AP tests. —chris walker, creative director Watch the trailer: https://www.youtube.com/watch?v=35nDYoIwiA8 Play now: https://bit.ly/3K8tXJL https://bit.ly/42dM61j May 8, 2023 at 02:14PM

Show HN: Git Hooting https://bit.ly/42a1RGh

Show HN: Git Hooting 00's called, they want their RSS feeds back. I was looking at my growing Github gist collection when a sudden urge to blog and make a name for myself "by not programming" struck. Part way into implementing my oh so special static website generator it occurred to me that, quite frankly, Github gists is a pretty decent publishing platform. I mean, it gives you reasonably extended markdown with previews, heck I could even write in org-mode, has comments, follower - followee relationship, extended search with filters, check out locally and push your edits. Did someone say "edit button"? Thus the idea behind https://bit.ly/3pjJAHX was born: collect gists into RSS feeds and force everyone, kicking and screaming, into the good old days when Google Reader was king. Well, it's a bit more than that now. But basically, you create a gist or grab an old one, name its main file `hoot.md` or `hoot.org` if org-mode is your poison, make it public and voila. These "hoots" make it into your RSS feed and will get permalinks with social graph metatags, so you get nice previews when you share them on Twitter and such. To take it for a spin: - pick a subdomain e.g. foo.git.ht, - navigate you browser there, - login with Github. I still consider it alpha, but it should work. Report any issues as you would normally on Github https://bit.ly/3HMeNdc . Thank you https://bit.ly/3pjJAHX May 7, 2023 at 01:29AM

Show HN: WebGPU Rotating Cube https://bit.ly/3M1rweL

Show HN: WebGPU Rotating Cube This is a small "hello world" type WebGPU demo that fits in a single page (no NPM dependencies or build steps). The last time I touched anything graphics-related was the OpenGL 1.x era, and I've been hoping WebGPU would be a good opportunity to come up to speed with modern standard GPU programming. However, the WebGPU tutorials I found were often small fragments of code aimed at people already familiar with DX12 or Metal, and the rest involved complex NPM build steps or "clone my repo to get started" setup scripts. This page is just a plain HTML+JS file. You can edit the shaders live from the textboxes, or download it to make more involved edits. I hope it feels something like what learning JS used to be like in the days of MySpace and Geocities (in a good way). https://bit.ly/429d5uB May 6, 2023 at 02:46PM

Show HN: Ethereum address reviews, similar to Yelp https://bit.ly/3nATHb2

Show HN: Ethereum address reviews, similar to Yelp Hi HN, Excuse me if the formatting sucks, this is a first time post. I want to introduce to you vrfd.info. A place where you can openly view and influence the reputation of any Ethereum address. Think of it as Yelp but for Eth. Addresses are classified as either verified or flagged on-chain through soulbound NFTs. A type of NFT that has no trade value as it cannot be sold. Once minted, it is stuck to the given address. The metadata of the NFT contains either information to verify the address with, this could be a social account for example. Or in the case of flagged addresses, the metadata contains proof of wrong-doing. Users can search the classification status of any address on the web app. Additionally, users can apply to either verify or report an address, provided proof. In the case of reports, users stand a chance to be rewarded. Finally, users can up or down vote other addresses. I made this tool after suffering one to many scam without having an open source library where addresses can be reported or their credentials verified. It's still a bit clunky, but the core concept works fully integrated on the Testnet. I'm shipping a big update this week to make it more responsive. Thanks for taking the time to read this. Please give me any feedback as I am looking to improve everywhere I can. https://bit.ly/3HJnGEy May 5, 2023 at 06:30PM

Show HN: Make domain verification as easy as verifying an email or phone number https://bit.ly/41nLwgh

Show HN: Make domain verification as easy as verifying an email or phone number Hi HN, This is a project [1] I've been working on for a little while and I'm interested in your feedback and point of view. Many of us would have verified a domain name by pasting a string into a DNS TXT record. Some providers ask us to store this DNS TXT record at a domain using a DNS label like "_provider" e.g. _provider.yourdomain.com, and some providers ask that you do it at the zone apex (God help us [2]). The Domain Verification protocol stores a DNS TXT record at a DNS name derived from a hashed "verifiable identifier" (think email, telephone, DID), enabling anyone that can prove control over the verifiable identifier to prove authority for the domain name. For example, the domain verification record giving the email address user@example.com authority over the domain dvexample.com can be seen with this terminal command: dig 4i7ozur385y5nsqoo0mg0mxv6t9333s2rarxrtvlpag1gsk8pg._dv.dvexample.com TXT The record can specify what type of services the authorised party is allowed to use (e.g. SEO, Storage, Advertising) or specify an exact provider (ads.google.com), you can also specify an expiry date. The benefits of this approach are: - Domain owners can grant time-limited, granular permissions for third parties to verify a domain - Every service provider could use the same verification record - Once a domain owner creates a verification record by following instructions from one service provider, that same record could be used by other service providers - Domain registrars could set these records up on behalf of users, perhaps even upon domain registration (with registrant opt-in). This would provide domain registrants with a fast lane for signing up to services like Google Ads, Facebook Ads, Dropbox, whatever I'm still working on licensing but creating these records will always be free. I hope to find service providers that see significant upside in reducing friction for user onboarding that are willing to pay to license it. Worked example: Let's say you want to authenticate the user with the email user@example.com with the domain dvexample.com, these are the steps: 1. HASH(user@example.com) -> 4i7ozur385y5nsqoo0mg0mxv6t9333s2rarxrtvlpag1gsk8pg 2. Store Domain Verification record at: 4i7ozur385y5nsqoo0mg0mxv6t9333s2rarxrtvlpag1gsk8pg._dv.dvexample.com 3. TXT record determines permissions and time limit: ``` @dv=1;d=Example user emali;e=2025-01-01;s=[seo;email];h=4i7ozur385y5nsqoo0mg0mxv6t9333s2rarxrtvlpag1gsk8pg ``` BTW, if you're interested the syntax of that DNS record is a compact data serialisation format I created especially for DNS [3].
