From the NASA website: "Among the tasks is a checkout of the toilet."

I meant searching for the UPC code in the store's own inventory system, not in the general internet. There are other ways of doing it than downloading a separate app for each store. For starters, it could easily be done by a web search on the store's webpage. I would scan the code on any QR code scanning app, and then paste the UPC on a search field in a webpage that I could easily find in the store. It would be easier to implement than dedicated hardware kiosks.

I'm surprised to find out that the Guinness Book of Records serves as a registry of scientific achievements. Here's the entry and a few other scientific records:
Smallest QR Code
Smallest Transistor
Lightest Black Hole
Brightest Star viewed from Earth

Ironically, the name of the university that made the feat, TU Wien, is not mentioned in the slashdot summary, but the Gunness Book of Records is.

The NASA news-release mentions "Skyfall payload of Ingenuityclass helicopters", for Mars. spacenews.com mentioned Moonfall instead. I wonder how they write their articles.

Rust depends on external libraries more than other languages do, because the Rust standard library does not include "core concerns such as async support, HTTP handling, and cryptography", as per the article. Languages like Java, and Go have large standard libraries that do all these things. Rust does not. I believe Rust has a philosophy of not wanting to commit to specific libraries, but instead let programmers pick the best libraries.

When I go to a store, I would like to be able to scan product UPC codes and see the current price for those products. This is also useful if the price tag is missing or if I can't read it, because it is too small, or too far (at the bottom shelf just above the floor), or because my eyesight is not sharp enough. Is this a lot to ask for?

I want to be able to do this this without installing the store's app, but with a 3rd party app (or my own). I also want to be able to scan the receipt and get an itemized price-list of what I bought.

Digital price tags are a convenience for the store. What I'm asking is a similar convenience for the customer.

Artificial light is already used for earth farming in some cases. But, to make use of the summary's "Solar" typo, I wonder if plants could also grow under the 28-day day cycle of the moon. If they could grow on 14 days of continuous light (artificial or not) and 14 days of darkness, then it would be easier to provide light for such a farm, either with natural sunlight, or via PV, without needing batteries or long power transmission cables.

There is a similar, but more informative article about growing Chickpeas on 75% moon soil.

These articles bring up interesting questions about circular farming. What would it take to build a closed ecosystem on the moon that does not require continuously shipping nutrients from earth?

Your computation assumes that you are storing 1 GW produced continuously for 24 hours. Solar power plants produce their nominal power only for a few hours each day. A good rule of thumb is 4 hours of nominal power per day. Therefore you need to divide your computed cost by about 6. If you also consider that a large portion of the power is consumed during the time that it is produced, the storage requirement is even lower. On the other hand, you may want more than overnight storage, for cloudy days. We recently read news about iron oxide batteries with 100 hours charge/discharge cycle, that may be more economical for several days worth of storage.

It says here, that "the spacecraft has used its remaining propellant to keep its solar panels pointed at the Sun and is now out of fuel." Why wasn't it using electric motors instead of propellant to orient the solar panels?

The day you turn 18, the apps will know that you just switched age brackets, which is equivalent to knowing your DOB.

I just tried searching for "Rolling Stones" and found fakes of the real thing. How does this protect artists? They could at least include the year that the band was created or joined Bandcamp.

Writing helps us process information that we've gathered. A better writer is a better thinker. We've already lost much of our physical ability by having machines do the work for us (driving, instead of walking or biking). Now we're starting to delegate mental skills to machines.

On the other hand, ancient civilizations, like that of classical Greece, achieved a high level of culture with much less writing as we have available today (because writing materials were so much more expensive). But they used a lot of oral communication, which is faster and probably more effective than written communication.

A better approach then would be for the reporter to converse with the AI orally, before the AI writes the article. Then the reporter could process information by talking to the AI on the way to/from interviews and meetings. How far along are oral chatbots?

Shouldn't everything be decided by democracy, including the financial system (whatever that means), and corporate reform? Do they have anything to propose about how to improve "deliberative democracy"? That alone would be a good start.
