Fish Spending Money

"In Japan, pet fish playing Nintendo Switch run up bill on owner's credit card"

Mutekimaru had previously installed sophisticated motion detection tracking software in fish tanks, enabling the fish to remotely control a Nintendo Switch console...

During the next seven hours, the fish reportedly managed to change the name of their owner’s Switch account before twice logging into the Nintendo store, where users can purchase games and other downloadable content.

They also managed to “check” legal terms and conditions, downloaded a new avatar and even set up a PayPal account from the Switch – sending an email out to their owner in the process, video from the livestream appeared to show.

But things didn’t end there. The fish were also seen adding 500 yen ($4) to Mutekimaru’s Switch account from his credit card during the livestream -- exposing his credit card details in the process...

AI Voice Simulation

"Microsoft's new AI can simulate anyone/s voice with 3 seconds of audio"

Microsoft researchers announced a new text-to-speech AI model called VALL-E that can closely simulate a person's voice when given a three-second audio sample. Once it learns a specific voice, VALL-E can synthesize audio of that person saying anything—and do it in a way that attempts to preserve the speaker's emotional tone.

Science Of Silly Walks

This is a great paper in the BMJ (British Medical Journal) on the metabolic effects of adopting the "silly walks" from the classic Monty Python skit.

The Cleese version of the silly walk (Mr. Teabag walk) burns off 2.5x the energy due to "walking inefficiently".  The Palin version (Mr. Putey walk) not so much.

Insecure Department Of Homeland Security

"Department of Homeland Security Can't Even Secure Its Buildings Against People It Fired"

A new report by Homeland Security's Office of Inspector General shows that the department is systemically failing to revoke tens of thousands of “personal identity verification” cards that allow staff to enter sensitive, secure facilities and access internal data networks, despite being warned about the problem for 15 years. The issue is made worse, the report continues, by the fact that Homeland Security’s internal record-keeping is so shoddy that it was impossible to determine how many ex-staffers have working access cards they aren’t supposed to.
