Fun Fact: Diffractive optics exhibit chromatic aberration in the opposite direction to Refractive optics, so the two can be used together to cancel each other out! Of course, that …

Perhaps they should have started at the Wikipedia entry for “Zone Plate” instead

I wonder if it will allow syncing WASM Emulators like N64Wasm… Would be awesome to use it to enable online gaming!

There are mechanical ambient noise generators that generate sound via fans and rushing air in a special cavity; a popular one is the Marpac Dohm. I've considered 3D printing custom…

That’s a shame; I hope they’re allowed to come back in a revised article. …or perhaps Nature felt it was too early for a discovery of this magnitude to be published ;-)

Kasm is a self-hosted alternative that’s free and avoids the security issues.

Mixing graphite into HDPE appears to make it immune to UV photo-degradation. There’s even a company that capitalizes on this by making durable boat hulls with it: https://tidemanbo…

I've noticed Apple products can feel like they buzz when plugged in, but I assumed it was just the inverter and poor grounding... Do you think a multimeter or oscilloscope would be…

You can even get an OpenCascade IDE running in your browser! https://github.com/zalo/CascadeStudio

Actually base-OpenCV has a great function for this: `cv2.findTransformECC()`: https://learnopencv.com/image-alignment-ecc-in-opencv-c-pyth... It can do dense translation, translati…

Are you kidding? If someone really has good evidence for the Earth being flat, that could potentially be one of the most important observations of all time! As the Litany of Tarski…

Since the train only shakes side to side (and not up-down or forwards-backwards), you only really need spring dampening along one axis. While you could set up a linear rail with so…

While they might be linked, I find it difficult to believe modern males have lower testosterone than pre-80’s females (which I’d expect if simply “Low-T” was causing the current su…

Another interesting clue to add to a growing body of evidence that the obesity epidemic is due to an unidentified environmental contaminant and not explicit changes to diet or “dis…

Even worse, two parties with animosity against each other will rank each other at the bottom of stack, allowing the generally amicable independents to sweep the election. It’s the …

Everything in BotW has that formulaic/modular/cookie-cutter feel that a Bethesda game does. None of the side quests particularly stood out to me, whereas I’ll frequently recall hid…

Many of these are similar to malaphors: https://www.reddit.com/r/malaphor/ https://www.reddit.com/r/Malaphors/

Can’t we tell whether the 4% difference between SARS-Cov2 and RaTG13 is responsible for the Furin Cleavage site? If so, that would be a huge connection suggesting GoF and the templ…

Would be nice to see Intellisense-style hover tooltips on code-blocks someday (via referencing a `.d.ts` or `.ts` file). There might be some minimalist way to get Monaco into read-…

Hi HN, I've been working on this tool for the last couple of months, and I feel like you guys might appreciate it. I love OpenSCAD, but it's showing it's age. So I decided to build…

There's a recent presentation on one from NASA: https://core.ac.uk/download/pdf/286393566.pdf

I discovered Peer Calls last night and think it’s an awesome project! It worked flawlessly from both my phone and desktop; it’s one of the (surprisingly few) fully featured WebRTC …

Nice UI; I really like the timeline view! I would highly recommend adding .webm export (since Browser-based .webm encoding strongly correlates with the ScreenCapture API). If you'd…

Hi Paul, I'm a big fan of your work democratizing holography, and I love the idea of a small-scale hologram printer. If you need any assistance with a Unity, Three.js (WebGL), or S…
