Deepfake Satellite Imagery Poses a Not-so-Distant Threat (theverge.com) 30

Long-time Slashdot reader AmiMoJo quotes the Verge's warning about "deepfake geography: AI-generated images of cityscapes and countryside." Specifically, geographers are concerned about the spread of fake, AI-generated satellite imagery. Such pictures could mislead in a variety of ways. They could be used to create hoaxes about wildfires or floods, or to discredit stories based on real satellite imagery... Deepfake geography might even be a national security issue, as geopolitical adversaries use fake satellite imagery to mislead foes...

The first step to tackling these issues is to make people aware there's a problem in the first place, says Bo Zhao, an assistant professor of geography at the University of Washington. Zhao and his colleagues recently published a paper on the subject of "deep fake geography," which includes their own experiments generating and detecting this imagery... As part of their study, Zhao and his colleagues created software to generate deepfake satellite images, using the same basic AI method (a technique known as generative adversarial networks, or GANs) used in well-known programs like ThisPersonDoesNotExist.com. They then created detection software that was able to spot the fakes based on characteristics like texture, contrast, and color. But as experts have warned for years regarding deepfakes of people, any detection tool needs constant updates to keep up with improvements in deepfake generation.

This is just the usual bullshit. Einstein was an asshole who ripped off some 18. century math and took the credit for it and by doing so gave the final deathblow to the use of Maxwell's original 20 equations which actually did provide the math you need to understand dark matter long before Einstein even was born. When you drive a car around a corner and feel your body being pushed to the side, that's you pushing against dark matter. It's as simple as that, but the strategic advantage which this knowledge provides, renders it cosmic top secret (pun intended :)

This used to be a fun site. Now it's suddently full of M$ lovers and whatnot! Every programmer with a shred of selfrespect knows that Microsoft is fracking evil! And all of their fracking products sucks like nothing else. I should bitchslap every single one of you .NET whores with the sorry excuse of an OS you rided in on. I'm ashamed of you all.

We did exactly this, worked wonders! After years of assigning roles and responsibilities without ever getting meat on our intranet - the only place anyone documented anything - I got fed up, closed it and set up a mediawiki in its place. Ported some of the old intranet, documented as much of my stuff as possible to build a skeleton and get things rolling, and after only two weeks, people who WANTED to contribute, did.
