Show HN: Ranking weather models by how their forecasts turned out

Hacker News - Thu, 08/06/2026 - 10:01am

Weather apps all claim to be accurate but never show their work. So I built a scoreboard that checks: it takes the forecasts each model published (ECMWF, GFS, ICON, AIFS and others, plus Apple Weather, Foreca, OpenWeather and Visual Crossing), waits for the weather to happen, and scores temperature, wind and rain against observations.

A few things that surprised me: - AIFS performs very well, yet almost no commercial apps give you access to it or uses it in their blend (I suspect some do without disclosing it tho) - Foreca scores surprisingly well compared to other apps and raw models - ICON is very accurate around the mediterranean, but performs quite poor everywhere else

There's also a history page that scores each model back through its full archive (about 5 years for GFS) to see if forecasts have actually gotten better.

It's a static page and open-source: https://github.com/NickLeenders/verisky-scoreboard. Public models are scored in your browser against Open-Meteo's archive. Commercial scores come as small aggregates from my server, because those providers' terms don't allow redistributing raw forecasts.

It powers an app that does the same per location in more detail, link is on the page.

Happy to answer questions about the scoring method.

Show HN: How will the Aug 12 eclipse look like from your address?

Hacker News - Thu, 08/06/2026 - 9:03am

August 12 is a total solar eclipse over Iceland and northern Spain and partially across Europe. In France it'll be visible over 90% (~92% in Paris at 8:17pm).

I wanted to know if I can view it and from where (with proper protecting glasses of course :). I built a site to help see it: you type your address (in France only for now, there's a default address you can click on to try it) and it shows you how it'll look like. You can also see the details of the eclipse for multiple cities.

Try it here: https://eclipse2026times.com/

Basically, using IGN's open data (https://www.ign.fr/), a ray is cast along the sun's azimuth and you'll see if the line of sight is clear. You'll see the fully rendered street in which you'll be able to move around and the tool puts you automatically on the lowest floor from which you can get a clear view to see the eclipse. All done in the browser client-side, nothing server-side.

Keep in mind you can't yet see cloud coverage and sometimes building data is outdated. There are probably other improvements to make as well.

Let me know what you think and if there's any features you'd like to see.

Ask HN: Do you rehearse with AI before seeing a doctor or dentist?

Hacker News - Thu, 08/06/2026 - 9:03am

I do.

For me, the benefit is greater than the privacy risk. AI helps me find the right words to explain precisely what I am experiencing and organize what I want to ask.

Show HN: Live Embedded Dashboards on Your GitHub Repo Page

Hacker News - Thu, 08/06/2026 - 9:03am

The link is to our GitHub template repo. Just follow the instructions to get the dashboard templates on your repo. You put the SlickFast URL endpoint inside your readme. There are multiple templates on the page to choose from.

It's very easy to create your own style, or to add whatever metrics you want, if you want to go custom.

SlickFast is a new svg native render core without headless chrome or other library calls. SlickFast has 47 chart types that can be combined in any arrangement or aspect ratio. An entire dashboard is just one image render.

SlickFast has MCP and is made for agentic workflows. Hook it up to your agent, tell it what you want. Opus tier models can basically one shot new dashboards.

Github accepts SVG input. (SlickFast does SVG+PNG output)

SlickFast is free and open source under AGPL. github.com/slickfast/slickfast

SlickFast runs locally unless you use the API.

I hope I see some cool designs!
