Hey everyone
i made this website to solve a big problem for me--upscaling my local videos the same way streaming players get upscaled. vlc did nothing but fail me and i didn't wanna install a random player just for this ine feature. if you want something that makes your local videos look better with a really cool looking ambient glow light feature that requires no download or internet, check this out (p.s. not for mobile!)

I built this from New York City's Open Data portal's dog licenses data file, which lists each dog's name, breed, and birth year, and the owner's ZIP code. The 2026 file has 96,459 dogs, and the site places them across 197 neighborhoods (Neighborhood Tabulation Areas).

Things to try:

• Type a breed or a name like "Labradoodle" or "Luna" into the search box, and the map shows where it is most common.
• Put "vs" between up to four breeds, names, or boroughs to compare them, as in "Luna vs Bella" or "Brooklyn vs Queens."
• Click a neighborhood to see its top breeds and names, along with the ZIP codes its numbers come from.
• Zoom in far enough and the dogs ride the subway on the real routes. Click a train to follow it!
• Add your own dog. You get a card comparing them with the city, a subway ride, and a turn in the Central Park or Prospect Park game, and the dog stays in your browser.

A license records only a ZIP code, so every neighborhood figure is an estimate. The code and the method are open source, accessible here: https://github.com/firatciftci/every-dog-in-new-york

I'd like to share a personal project I've been building.

Maparium lets you display thousands of OpenStreetMap features globally, from wind turbines, power plants and castles to volcanoes, spaceports, railway networks and data centres. You can switch between predefined layers and explore patterns that are difficult to spot when looking at individual locations.

I'm using MapLibre GL JS, a Protomaps basemap and custom MBTiles generated from OpenStreetMap data. A big focus has been making the experience fast and lightweight, even when displaying features on a global scale.

I'm building this mainly for fun and curiosity.

It's still a work in progress, but I'd love to hear what you think!

What other OpenStreetMap features would you like to explore this way?

I made Metroskop, an interactive 3D visualization of Prague's metro system.

You can explore the entire network, see how deep the stations actually are, follow the tunnels underground, and discover some lesser-known parts of the system.

It's free, works in your browser, and there's nothing to install.

Thought some of you might enjoy exploring it.

Have a great day!

I was interested in the music artists I liked, and wanted to create a much more comprehensive way to view the connections artists may have with each other. It's just a fun project, let me know what you think!

Data comes from Youtube Music public playlists for connections and Deezer for artist info (since spotify/apple doesnt share anything)

I got really tired of podcast platforms that build walled gardens between listeners and the open internet. Podcasting works because it's built on open formats and protocols. It's why the phrase "wherever you get your podcasts" works (see this great post: https://www.anildash.com/2024/02/05/wherever-you-get-podcasts/).

wherever.audio embraces this philosophy, deeply:

• Runs on any device with a modern browser.
• Runs entirely client-side, including RSS parsing. Nobody decides what you can see or watches what you listen to.
• Add any RSS URL to https://wherever.audio/show?rssUrl=
• Installs to your device as a PWA, so you can run it offline or on private networks.
• No proprietary feed or episode identifiers, just RSS, creator-provided episode GUIDs, and Podcasting 2.0 feed GUIDs.
• Clips are just start/end times added to the URL. The recipient's player uses range requests to stream the clip straight from the podcaster's server. If you download before clipping, we can even provide word hints to help the recipient find the right offset.
• QR code sharing; everything is a URL.
• Strong support for import/export, including OPML. Your data lives on your device and we help you move it wherever you want.

Caveats: a small helper server handles podcast search and CORS for publishers that don't set headers for their feeds. It's one of very few places where we have infra. Requests carry no personal data and logs are deleted after 60 days. Also, the app is not open source.

Given all that, I'm very interested in feedback, either on the player itself or, if you don't listen to podcasts or are happy with your current player, on ways we could more fully embrace the open web. What else would you want to see?

Hey, after rewatching all 25 Bond films I wanted to see every filming location in one place, so I built this. It's a free fan project. I'd love corrections and missing locations, there's a "field report" form for that.

I’ve been building this antenna/EM simulator as a side project:

https://rotemtsafrir.github.io/dipole_sim/

The idea is to make it easy to place antennas, change their parameters, and immediately see how the fields and interference patterns change.

Right now you can use:

• center-fed dipoles
• Hertzian dipoles
• small loop antennas
• linear antenna arrays

The arrays are probably my favorite part so far. You can adjust spacing, phase difference, element count, orientation, etc., and see beam steering / broadside / end-fire behavior directly.

You can switch between electric field, magnetic field, and energy-flow visualizations, and pan/zoom around the simulation.

The antenna currents are prescribed, so things like mutual coupling, impedance, and passive conductors are not solved yet. I’m trying to keep it fast enough to be genuinely interactive.

I’d love to hear what people think—especially if you notice anything physically questionable or have ideas for features that would make it more useful.

I made a 3D interactive solar system you can navigate and set to any date between 1000 and 3000. The positions of the planets and moons are computed from VSOP87-type models and checked against JPL Horizons data, accurate to within 30 arcseconds for planets and 30 km for the Moon over 1800-2050, so eclipses, alignments, and moon phases are physically real. It's still a work in progress, so feedback is wanted. If you try it and something feels off, confusing, or worth adding, I'd be glad to hear it.

Hi all, I've been working on this and thought some of you might enjoy it: https://slidingshores.com

It's a 3D globe with one slider, which you can Drag left to the sea drain away, all the way down to the bottom of the Mariana Trench. Drag it right and the water rises until it goes over the top of Mount Everest. The coastlines change as you move it, and a counter shows how much of the planet is dry land.

There are also some preset buttons for real moments in Earth's history, plus a few possible futures:

• Ice Age (−120 m): Britain joins back up with Europe through Doggerland, and you can walk from Siberia to Alaska
• Mediterranean drained (−1,500 m): about 5.5 million years ago the Med almost completely dried up. When the Atlantic broke back through at Gibraltar, it may have refilled in a matter of months
• Ridges surface (−3,800 m): the mid-ocean ridge comes out of the water, and it turns out to be the longest mountain range on the planet
• Greenland melts (+7 m) and All ice melts (+70 m), for a cheerful ending 🙃

The elevation data is NOAA's ETOPO 2022, which covers both the land and the sea floor. It's a bit of fun rather than a scientific model, since it doesn't account for where the water would actually go, but the heights and depths are real.

Enjoy!
