#Deepfakes are everywhere, but #DigitalForensics investigators are fighting back:

To verify images, digital forensics investigators will often check whether the geometry of the scene is realistic. In a real photo, lines that run parallel in reality—like floor tiles—should meet at a single vanishing point. In this image, however, the dotted lines do not meet in a single point, indicating it is a fake.
Image: an AI-generated image of soldiers marching down a hallway in three lines, wearing fatigues and carrying rifles. Four dotted white lines have been added over the image, running along the floor tiles visible in the foreground and extending back to where the vanishing point should be, behind the soldiers. Instead of meeting in a single point, the lines all cross at different points. — To verify images, digital forensics investigators will often check whether the geometry of the scene is realistic.

Investigators also examine reflections. The lines connecting points on an object to matching points in its mirror image run parallel in reality, so similarly should meet at a vanishing point. In this image, the lines again do not converge on one point, revealing it to be a fake.

Four dotted white lines are layered over the image, connecting points on the toy with the same points on its reflection: the top of its eye, the end of its jaw, its hand, and its foot. The lines extend out to the side of the image, where they all cross at different points rather than meeting at a single point. — Investigators also examine reflections.

One of my most fervent education takes is that we should be teaching programming earlier, and more than manual arithmetic. By high school, no student should be carrying the 1 on a math test.

@mttaggart I totally agree,

The same is true for stochastical problems. I once could not believe the Monty Hall problem.

So I just wrote a simple sampler with randints following the two solution paths and collect the wins. This helped me a lot, understanding the problem.

客户压缩我工期，我就在现场天天给他们员工散布仇恨的种子。“这工资很难留住人的吧？你谈对象了吗？”“文具还要申请？也太抠了，知道你们公司今年股票涨了几倍吗？”“加班费有没有？”

来互相伤害吧！

…The third 6 of 18 sections in https://how.complexsystems.fail:

13. Human expertise in complex systems is constantly changing

14. Change introduces new forms of failure

15. Views of ‘cause’ limit the effectiveness of defenses against future events

16. Safety is a characteristic of systems and not of their components

17. People continuously create safety

18. Failure free operations require experience with failure

Bishop Swan is on my list of favorite Christians in America.

As for the white evangelicals he talks about in this quote, I offer another quote: “Your boos mean nothing. Over seen what makes you cheer.”

Only a white man in America can…
- Be videotaped with underaged girls 3 while hanging with a child sex trafficker
- Cheat on his wife with a porn actresses and pay her to keep quiet a
- Publicly fantasize about having sex with his own daughter
- Openly boast on tape about sexually assaulting random women
- Be convicted of 34 felonies, have 91 criminal charges, 26 sex assault allegations, 5 bankruptcies, and 2 impeachments
- Be sued by the Department of Justice for racial discrimination
- Have a $25 million fraud settlement, a $400 million fraud judgment, and of $96 million sexual assault judgments

…and be considered a good Christian by white evangelicals and elected president of the United States TWICE.

I really tried with the older ones, starting with Troughton, but they were long and cardboard. Then I skipped to Baker and wanted to love it, but it was long and impenetrably weird. I know I should like it, so might try again at some point. I'm currently hyperfixated on Dungeon Crawler Carl and have just done the first 7 books and now have to wait for the new one to come out next week, so it'll be interesting to find out what my next deep dive will be. Will it be a healthy obsession or yet more self-destruction?! Who knows?! Tune in next week to find out, on...... The Ben Show! 🎺
