Show HN: Near-realtime cloud maps for weather visualisation, 3D models and more
This is a service I've built to provide equirectangular cloud maps of the whole Earth, updated every 3 hours, for free.<p>It's based on infrared and visible light data from EUMETSAT, processed to enhance the clouds and try to reduce the impact of surface temperatures on the final image.<p>I built it because it's surprisingly hard to find these kinds of images in a format that's useful to developers and hobbyists. I was building a 3D ISS tracker and wanted to include live clouds but couldn't find anything good, so I got sidetracked, and here we are.

Also, yes I am looking for a new role. And yes, I should have been spending my time looking for suitable roles instead of building this.

Show HN: Convert any screenshot into clean HTML code using GPT Vision (OSS tool)
Hey everyone,<p>I built a simple React/Python app that takes screenshots of websites and converts them to clean HTML/Tailwind code.<p>It uses GPT-4 Vision to generate the code, and DALL-E 3 to create placeholder images.<p>To run it, all you need is an OpenAI key with GPT vision access.<p>I’m quite pleased with how well it works most of the time. Sometimes, the image generations can be hilariously off. See here for a replica of Taylor Swift’s Instagram page: <a href="https://streamable.com/70gow1" rel="nofollow noreferrer">https://streamable.com/70gow1</a> I initially had a hard time getting it to work on full page screenshots. GPT4 would code up the first couple of sections and then, get lazy and output placeholder comments for the rest of the page. With some prompt engineering, full page screenshots work a whole lot better now. It’s great for landing pages.<p>Lots of ideas of where to go from here! Let me know if you have feedback and you find this useful :)

Show HN: GPT-4-Vision UX audit for your landing page (relaunch)
Last week, I got seriously fascinated by the new GPT-4 Vision API introduced on OpenAI DevDay, so I decided to build a UX Audit tool with this API.<p>It's pretty simple to use - just go to <a href="https://flawless.is" rel="nofollow noreferrer">https://flawless.is</a> and enter your homepage or landing page URL.<p>I'm using the urlbox API to get a screenshot of your page, then I utilize GPT-4V to analyze the screenshot, find potential usability and conversion issues, suggest fixes, and highlight the relevant areas in the screenshot (although the position is sometimes inaccurate).<p>Last week, I launched it on Hacker News (<a href="https://news.ycombinator.com/item?id=38207892">https://news.ycombinator.com/item?id=38207892</a>), but I wasn't ready for the 20,000 visitors that came next... Unfortunately, GPT-4V has a rate limit of 100 events daily, so almost no one could use the service - EPIC FAIL.<p>To manage demand, I now priced the service at $1.99 (still less than a cup of coffee), which should keep the demand at bay, and also cover the costs of GPT-4V, the screenshot API, and hosting.<p>As a proof of concept, there are some demo audits on the homepage you can click and check out.<p>Please let me know your thoughts and suggestions on how to improve it!

Show HN: Extend your platform via custom code with Deno Subhosting
Hey all, Andy from the Deno team here. We're excited to share with you Deno Subhosting, an easy way to extend your platforms functionality by securely running untrusted JavaScript written by your users.<p>When we first launched Deno Deploy in 2021, we were surprised at the volume of requests from companies about getting access to the APIs needed to run Deno Deploy. Many companies wanted to give their users the ability to write custom logic in their app, but setting this up in the cloud presents security concerns and a ton of infra work/maintenance.<p>We realized that there was an opportunity for Subhosting to solve a larger problem, which is allowing companies to easily and securely run custom code written by their users, without the hassle of maintaining said infrastructure.<p>Though we do have a few subhosting customers (Netlify being one of them), this launch makes our Subhosting product self-service, so any development team interested in extending their platform via their users' custom code can do so by signing up and reading our docs. We have an updated pricing model for Subhosting as well, including a generous free tier fit for kicking the tires and building a proof-of-concept.<p>We'd love to get your feed back. Have you ever talked to your co-workers about allowing external devs to "have at it" with your platform? What would it look like to unlock the final 10% for your top customers? How have you approached this problem in the past?<p>Thanks for reading and the Deno team will be responding to comments!
