An orrery is a mechanical model of the Solar System that illustrates or predicts the relative positions and motions of the planets and moons, usually according to the heliocentric model.
This simulated view of our solar system runs on real data. The positions of the planets, moons and spacecraft are shown where they are right now.
Runs better in Chromium-based browser (didn't work in my Firefox).
Web-based book. Looks really interesting. By Matthew Butterick, 2014.

The NIST Uncertainty Machine is a web-based software application produced by the National Institute of Standards and Technology (NIST) to evaluate the measurement uncertainty associated with a scalar or vectorial output quantity that is a known and explicit function of a set of scalar input quantities for which estimates and evaluations of measurement uncertainty are available.

An aggregator is only as good as the OTAs (online travel agencies) it canvasses. There are booking engines that find prices themselves (Expedia, Priceline, Hotwire). And then there are aggregators—sites that do not book tickets but instead search dozens of booking engines, airfare sites, and OTAs and compile the results in one place; you then click through to the one of your choice to make the actual purchase.

A Javascript tool to model tandem photocatalytic devices, by Brian Seger, assoc. prof. at DTU.
I first heard about it in a talk by Ib Chorkendorff (PECSYS, 201105).
Fantastic little tool. I used it on Baahubali 2, whose subtitles were drifting more and more with time, and it corrected it without any user intervention. Very nice!
It is even integrated into Bazarr (automatic subtitle synchronisation can be enabled in Bazarr's settings).
For 20 years, astronauts have been shooting photos of Earth from the space station. Like everything the astronauts do, they are trained for this job. And like everything they do, there is purpose and intention behind it.

I liked some quotes in this article:
If you are going to teach science, you must give it in a historical context: you must stress how our current knowledge is the accumulation of course corrections. You must stress how it is a work in progress.
Given that science is fundamentally subversive, how could it emerge and survive? I believe that scientific thinking is part of a broader ideology that gives its bearers an evolutionary edge. Simply put, societies that make room for science have an edge. They build and deploy better technology. They adapt more quickly to change.
Genom ett nytt samråd har byggprojektet Samsö, som var på samråd 2013, åter blivit aktuellt. Projektet innebär att Hökarängen och Farsta byggs ihop genom en förlängning av Lingvägen. I den nya planen föreslås tre bostadshus och en förskola samt en utbyggnad av Kvickenstorpsskolan.

Copenhagen is a great city, but it's not Amsterdam ... or any other Dutch city for that matter. This video explores the differences in street design taken by Copenhagen and citites in the Netherlands, to discover some of the finer points of what makes for great urban design.
The European Clean Hydrogen Alliance brings together industry, national and local public authorities, civil society and other stakeholders. It is strongly anchored in the hydrogen value chain, covering renewable and low-carbon hydrogen from production via transmission to mobility, industry, energy, and heating applications.
This could perhaps be a much more stable alternative to my reverse SSH tunnels for keeping connections with various servers, especially desktops inside FM-NET and other machines inside other LANs.
The main downside is that Tailscale is not FOSS. So perhaps we should look for other solutions built on WireGuard, or perhaps learn to configure WireGuard directly.
