Show HN: An API for CO₂ Removal
Hi all,<p>We're Fabienne and Ewan of Climacrux. Today we're proud to launch our latest project to try and make carbon dioxide removal as accessible as possible: CDR Platform [1].<p>In short: it’s an API to connect to a portfolio of carbon removers. You can purchase from as low as a single gram and select from both natural and technological removal methods.<p>Longer: A couple of years ago we launched an alternative to carbon credits, Carbon Removed[2], designed for individuals to buy and subscribe to CDR. But we always had the nagging thought that there was more that could be done.<p>CDR Platform is our foundation for that - a simple API to get prices and purchase (at the moment). Our plan is to become the Stripe of the carbon removal ecosystem, seamlessly connecting the supply to the demand.<p>We’d love to hear your feedback. Do you see a use case for this and would you use it? What features have we missed? Do you understand what we’re doing and if not, what’s unclear? We’d love to hear from you.[3]<p>Many thanks and happy hacking, Climacrux.<p>P.s. If you are a carbon remover, send us your prices, life cycle analysis and some more information about your removal timeline. Our aim is to bring your services to a wider audience so you can focus on reducing our CO₂ levels. Thanks for your work!<p>[1] <a href="https://docs.cdrplatform.com" rel="nofollow">https://docs.cdrplatform.com</a><p>[2] <a href="https://carbonremoved.com" rel="nofollow">https://carbonremoved.com</a><p>[3] ewan@climacrux.com
Show HN: Postcard – Easy way to make a personal website
Today I'm launching Postcard!<p>I started Postcard when I deleted most social media, but still wanted a way to keep in touch with friends and my network.<p>When I worked at Webflow, it became clear to me that most website builders are way too complex for individual users. So, I drew inspiration from social media - where all you need is a couple photos and text fields to get a great site online. So, I think I’ve about achieved a site builder that even my Mom could use.<p>The product seems simple, but there are many under-the-hood optimizations. There's caching, CDNs, custom domain support, TLS certificate issuance + management, dynamically-generated open graph images, image optimizations, email sending, full-text RSS feed, email reputations, and more. It also uses a couple new products to make the domain connection process easy.<p>Let me know if you have any feedback or questions!<p>PS - Rumor is that Twitter is shutting down Revue. If you want help transferring content and subscribers over to Postcard, just email me!

Show HN: HN Follow – email alerts from your friends on Hacker News
HN Follow lets you “follow” authors on Hacker News, and get email notifications when they post. It was inspired by alerthn.com and hnreplies.com.<p>The app was built in an experimental style. Instead of being a normal app where we store all your data, it is just a wrapper over a series of JavaScript snippets that we guide you through installing, and which you can then customize 100%. The scripts call out to Agolia’s wonderful HN Search API. You can read more about the app’s architecture and it’s motivation here[1].<p>HN Follow runs on Val Town [2], an online scripting tool my team and I are building. Part of why we built hnfollow.com is to show off the kind of things you can do with the primitives Val Town provides:emailing yourself (`console.email`), persistent state (`@me.foo = "bar"`), persistent cron jobs (`setInterval`), etc. Here’s a demo[3], the docs[4], and Discord[5] for Val Town.<p>We hope hnfollow.com is useful to you, and you have fun customizing the code directly on Val Town! Let us know if you have questions or feedback<p>[1] - <a href="https://www.notion.so/End-programmer-Programming-a749beb4a9b143f2990f575fb7e59b33" rel="nofollow">https://www.notion.so/End-programmer-Programming-a749beb4a9b...</a><p>[2] - <a href="https://val.town" rel="nofollow">https://val.town</a><p>[3] - <a href="https://www.loom.com/share/878294970d8e48919c819f35d0cd0da4" rel="nofollow">https://www.loom.com/share/878294970d8e48919c819f35d0cd0da4</a><p>[4] - <a href="https://www.notion.so/Val-Town-Docs-01c8eb9c534b4899802f3a9e31d540ab" rel="nofollow">https://www.notion.so/Val-Town-Docs-01c8eb9c534b4899802f3a9e...</a><p>[5] - <a href="https://discord.gg/dHv45uN5RY" rel="nofollow">https://discord.gg/dHv45uN5RY</a>
Show HN: Cito – Actionable data observability for data teams
Hi HN! We’re Clemens and Felix from Cito - thrilled to show you what we’ve built to help data engineers stay on top of data quality issues. Think Datadog meets Incident.io.<p>Tests in dbt are great when checking whether specific expectations are true, but don’t work well for use cases where data patterns may change over time. When relying on testing alone, data teams regularly face situations where business stakeholders identify data issues in dashboards first, eroding trust. In such situations, understanding the implications of an issue and debugging can be a very manual and time-consuming process.<p>To help data engineers ensure trust in data, Cito makes it easy to go beyond simple tests. By executing scheduled or near real-time out-of-the-box anomaly detection tests (row count, schema change, etc.) or custom SQL tests, data anomalies are detected and communicated in the context of the relevant column-level lineage via Slack.<p>We believe data observability solutions should not stop at alerting teams to anomalies and our ambition is to support the complete end-to-end workflow of data engineers. Leveraging column-level lineage, our solution makes it straightforward to understand the context of anomalies. In addition, by automatically providing transparency in a git-blame-like fashion around ownership of data models and showing who made changes most recently, Cito helps to accelerate internal communications when troubleshooting.<p>We’re super keen to hear your thoughts, ideas and experiences! You can also use our docs to try Cito in less than 15 min.

Show HN: Metadocs, kinda like Reddit, but built into every documentation
Hi, I'm Ritinkar and I'm building metadocs, which is kind of like reddit built into every documentation ever.<p>It's a chrome extension that allows discussion on any webpage to happen there itself.<p>Currently I have built threaded comments, and a upvote/downvote system.<p>Plus I've built this cool feature called Highlights, which lets you discuss specific lines in any documentation. As well as a feature called Top Hightlights, which shows the most interesting hightlights on any webpage.<p>Hope you guys will try it out. And if you have any questions, feel free to ask me here.<p>Thanks.

Show HN: All-SVG websites with complex animation
I created a system for building SVG-only websites called Svija. But, though the content was nice, the sites felt too static — a bit flat and lifeless. Even a basic HTML website has mouseover effects, but SVG doesn't have them for free the way HTML does.<p>I wanted to find an easy way to recreate mouseover functionality in SVG. For my first try, I labeled objects in Adobe Illustrator:<p><pre><code> • linkSomeName: an invisible link <rect> (over the link text)
• mouseoverSomeName: a <g> mouseover decoration (usually bold or colored text, or an underline), initially hidden
</code></pre>
The two objects are connected by "SomeName", and a javascript event listener attached to the link object would change the mouseover object's CSS display from "none" to "block".<p>Once I had used it for a bit, I thought that it might be nicer if the effects faded in and out. So, I tried animating the transitions with GSAP. It immediately became clear that there was enormous potential to manage complex animations visually, and I worked over the
summer to create Svija Vibe.<p>It's all based on linking Adobe Illustrator object names to the GSAP script. Most basic transformations already work well but there's a lot I'll be able to do to make it even simpler to use.<p>I'm really excited about it! I've only just started but I have a million ideas about how to make it more capable — the big one being the ability to chain animations together.<p>There's a support document at <a href="https://tech.svija.love/how/animation" rel="nofollow">https://tech.svija.love/how/animation</a> that gives more detail about exactly what can be done.<p>Svija Vibe is free. It works with Svija, which is also free, but you do need to create an account to use it (Maconly, at least for the next three months).<p><a href="https://news.ycombinator.com/item?id=29430368" rel="nofollow">https://news.ycombinator.com/item?id=29430368</a> · previous HN about Svija 2022-12-03<p><a href="https://news.ycombinator.com/item?id=30454324" rel="nofollow">https://news.ycombinator.com/item?id=30454324</a> · previous HN about animation 2022-02-24<p><a href="https://greensock.com" rel="nofollow">https://greensock.com</a> · GSAP
