Elon Musk: Force for anthropic advancement or self-serving con-artist?

He obviously fully understands food hygiene at these Tesla Diners

The Tesla diner is unfortunately in my neighborhood so I took a little peek to see boxes of milk and frozen foods out in the heat. Good luck to everyone’s stomachs.

Spoiler Just in case you need a close up :

This depends on how long they are there. Food truck deliveries typically can't be delivered literally from the truck into the freezer at most restaurants (not enough room in freezer to bring the whole pallet in there, needs to be set outside the freezer then manually disassembled and cases individually put on the shelves in the freezer.) Most places at least brings the pallets inside the building, but its common to not wheel it directly into the freezer.

15 minutes? Not a problem. A couple hours? Yes, thats a problem.

Just googled it, according to USDA, frozen packages can be re-frozen if set out a maximum of 2 hours. (if above 90 degrees, which i will say may be the case in the picture, the maximum time is reduced to 1 hour.)

Edit: and in second picture you can see the reflection of someone who may well be the delivery person (this stuff just got dropped off), or is a worker at the restaurant working on bringing this stuff inside.

Scientists analyze 76 million radio telescope images, find Starlink satellite interference 'where no signals are supposed to be present'

There's no doubt that SpaceX's Starlink internet service has connected the world like never before — but at what cost? Astronomers have long voiced concerns about Starlink's satellite constellation interfering with observations of the universe, and a new survey by Curtin University confirms those fears.

An analysis of 76 million images from a prototype station for the Square Kilometre Array (SKA) radio telescope found Starlink satellite emissions affected up to 30% of images in some datasets; such interference could affect research outcomes that depend on that data. The survey identified more than 112,000 radio emissions from 1,806 Starlink satellites, and found that much of the observed interference is not intentional.

"Some satellites were detected emitting in bands where no signals are supposed to be present at all, such as the 703 satellites we identified at 150.8 MHz, which is meant to be protected for radio astronomy," study lead Dylan Grigg, a Ph.D. candidate at Curtin University, said in a statement.

Grigg noted these unintended emissions might come from onboard electronics. "Because … they're not part of an intentional signal, astronomers can't easily predict them or filter them out," he said.

While the International Telecommunication Union does regulate satellite emissions to protect astronomical observations, current rules "focus on intentional transmissions and do not cover this type of unintended emission," said Steven Tingay, a Curtin professor and executive director of the Curtin Institute of Radio Astronomy.

However, it's not only Starlink satellites that are the problem. The study team's survey focused on Starlink because it currently has the most extensive constellation, with more than 7,000 satellites deployed at the time of the survey, but other satellite networks can "leak" unintended transmissions, too.

"It is important to note that Starlink is not violating current regulations, so is doing nothing wrong. Discussions we have had with SpaceX on the topic have been constructive," said Tingay. "We hope this study adds support for international efforts to update policies that regulate the impact of this technology on radio astronomy research that are currently underway."

For some values of wrong I would say.
