Yep! Here's a few hours of combined exposure of the radiation from an americium source from a smoke detector.

Depending on the content of the image, the compression ratio can vary a lot. The 26% figure is probably for "normal" photos. My images are mostly a few shades of black with a few white pixels (using a camera as a radiation detector) and I guess WebP is way better at compressing that than PNG.

The article says they kept 15% of the data for testing, so it's not overfitting. I'm still skeptical though.

The WebP format supports fully lossless compression in addition to lossy compression. I used the lossless mode for my images.

What do you mean? That's the total file size of the images before and after I converted them to webp.

It losslessly compressed ~150GB of my PNGs to ~75GB, so I'd say it's definitely better space-wise.

Just need to get a superzoom camera and zooooooooooom. :)

19 million miles is 102 light seconds.

They're new high tech lasers that go faster than the speed of light!

Yeah, you can disable iMessage in the Messages settings.

Same here, I'll definitely be trying it out.
