Submission + - China's Moon atlas is the most detailed ever made (nature.com)

AmiMoJo writes: The Chinese Academy of Sciences (CAS) has released the highest-resolution geological maps of the Moon yet. The Geologic Atlas of the Lunar Globe, which took more than 100 researchers over a decade to compile, reveals a total of 12,341 craters, 81 basins and 17 rock types, along with other basic geological information about the lunar surface. The maps were made at the unprecedented scale of 1:2,500,000. The CAS also released a book called Map Quadrangles of the Geologic Atlas of the Moon, comprising 30 sector diagrams which together form a visualization of the whole Moon.

China will use the maps to support its lunar ambitions and Liu says that the maps will be beneficial to other countries as they undertake their own Moon missions. Three spacecraft have launched aiming for the Moon so far this year, and in May, China intends to send a craft to collect rocks from the Moon’s far side.

How about Nomore Numbnuts instead? Oh wait, that's not an animal...

I DO wish that would become Ubuntu's motto though - maybe then they'd stop ramming Snaps down users' throats.

FWIW there are some pre-packaged applications that I like and use. But a) I favour AppImage and Flatpak over Snap, and b) I want the choice between APT and standalone. That's a major reason for me running Mint instead of Ubuntu.

Submission + - Russia vetoes U.N. resolution on nuclear weapons in space (spacenews.com)

schwit1 writes: Russia cast the only vote against the draft resolution that reaffirmed provisions in the Outer Space Treaty prohibiting the placement of nuclear weapons or other weapons of mass destruction in space. Thirteen other members of the Security Council voted in favor of the resolution while China abstained. As a permanent member of the Security Council, though, Russia’s vote acted as a veto preventing adoption of the resolution.

The Outer Space Treaty already forbids those, so this is basically a symbolic move on both sides. But to the extent that the Outer Space Treaty's prohibition is weakening, the prospects for a nuclear Orion spaceship improve.

Don't be a pedantic douche. "App" is short for application, which is synonymous with program. There is nothing special about "app," regardless of the fact that phones and "stores" refer that term.

He's not being pedantic, but rather historically accurate. They were called programs back then. Referring to them as "applications" was rare, and the term "apps" was even less common, if it was used at all.

I'd guess that DOS 3.3 was the most popular, followed by 6.22. Dos 4 was considered an oddball between-useful-releases release.

That was a long time ago, but IIRC my first computer - a Christmas gift from the boss - came with DOS 4.0. I "upgraded" it to Compaq DOS 3.31 - AFAIK Compaq was the only source for a '3.31' version. I only used 4.0 briefly - I remember not liking it but I don't remember why. It was generally treated with disdain by the programmers and other serious computer users I knew.

At that time I worked on analog hardware, so a computer was still a novelty and a toy for me. Then I got into CAD - no more drafting board needed to create mechanical drawings or schematics, nor to lay out a PCB. Good times...

sounds like she is less than open and honest herself. She took a new role prior to telling her new boss she would be taking maternity leave...

That's not quite accurate. From the article:

"On her first meeting with Marcu, she disclosed she was pregnant, information she had already shared with her previous manager. Marcu, taken aback, responded by informing Ghaderi that she would be 'temporarily' transferred to report to a different employee, Mahesh Krishnakumar."

So in the first place, it seems that she told her new boss about her pregnancy at her earliest opportunity. In the second place, even if that wasn't the case, she had told her former boss. It's not her fault that one hand didn't know what the other one was doing - she was open and up-front about her pregnancy.

High quality AR with normal glasses has an absolute crapload of obvious applications.

Oh? I do not see any in a private setting. Industrial setting, yes, and they are used.

I dunno. I think I'd use them to be entertained while I'm stuck with people I don't necessarily connect with but don't wish to offend. I might also use them to look up information regarding a movie or TV series I'm watching on a big screen without having to hit pause. And having a see-through schematic before my eyes while I'm building or working on some piece of equipment might be pretty compelling.

That said, they'd really have to be at first glance almost indistinguishable from my regular glasses - and they'd have to correct my vision as well. I can't imagine that would ever happen, at least not in what's left of my lifetime.

These projects are very important for the future, but only as experiments. Until we have an excess of 'green' power to allocate to sequestration, sequestration causes a net release of CO2.

Even plant-based sequestration can be a net negative, depending on any resources used to help it grow. Fertilizer production releases greenhouse gases, and over-fertilization of a field causes the release of N2O, which is a particularly potent GG. And if the plants end up rotting or catching fire, there goes all that CO2 back into the atmosphere.

We're still at the magical-thinking stage where we believe we can keep on going the way we are because science and technology will save us from ourselves. In reality we need to start consuming and producing less. It's not as though we even truly enjoy all this excess - if there was any happiness in it we wouldn't be so much like junkies itching for the next fix.

My wife and I shop in "bins" stores where stuff returned to Amazon and the like is re-sold. Much of it is perfectly good and fully functional - who knows why the purchasers rejected it. Yet most of it - countless thousands of tons - is ultimately destined for landfill. When I think of all the resources that went into making and shipping it, only to have it scrapped, sometimes I literally cry.

On the one hand, as TFA mentions, using electrical energy to remove CO2 from the atmosphere, instead of using it to directly lower carbon emissions, seems counterproductive. And the potential negative effects on sea life and pH balance could be catastrophic.

On the other hand, we may already have reached the point where, even if we went to zero greenhouse gas emissions tomorrow, temperatures might continue to rise as a result of emissions from melting permafrost, increased forest fires, etc. If that's the case, then we're really going to need carbon capture technologies like this to actually reverse global warming.

Computing power so sweet and so addictive, we're willing to add more big logs to the bonfire which is burning our civilization's future, just to keep the data flowing.

Are the benefits of all this computing power going to be distributed more-or-less evenly? Or is this another "the rich get richer, the middle class gets a few scraps, the lower classes are still more screwed, and more people in third world countries die" scenario?

Apologies for the rhetorical question - I'm coming a bit unhinged lately, thinking about our likely future or lack thereof, and about how utterly stupid and self-destructive we, as a species, have turned out to be.

Yeah.. You need a legal basis to force companies to violate their customers' privacy.

I'm happy to be schooled if I'm missing something obvious here, so I have to ask the question: why is it that companies are so reluctant to invade customers' privacy at the request of the government? They do it readily, on a daily basis, to further their own economic ends, so it's hard to see their objections as having a moral or ethical basis. The obvious "we're not getting paid by the government to do their spying" doesn't seem compelling enough under the circumstances, and the "you're not the boss of me" idea doesn't seem to fit either. So what gives?

Submission + - Ocean Spray Emits More PFAS Than Industrial Polluters, Study Finds (theguardian.com)

An anonymous reader writes: Ocean waves crashing on the world’s shores emit more PFAS into the air than the world’s industrial polluters, new research has found, raising concerns about environmental contamination and human exposure along coastlines. The study measured levels of PFAS released from the bubbles that burst when waves crash, spraying aerosols into the air. It found sea spray levels were hundreds of thousands times higher than levels in the water. The contaminated spray likely affects groundwater, surface water, vegetation, and agricultural products near coastlines that are far from industrial sources of PFAS, said Ian Cousins, a Stockholm University researcher and the study’s lead author. “There is evidence that the ocean can be an important source [of PFAS air emissions],” Cousins said. “It is definitely impacting the coastline.”

The Stockholm researchers several years ago found that PFAS from ocean waves crashing are released into the air around shorelines, then can travel thousands of kilometers through the atmosphere before the chemicals return to land. The new research looked at levels in the sea spray as waves crash by testing ocean samples between Southampton in the UK and Chile. The chemicals’ levels were higher in the northern hemisphere in general because it is more industrialized and there is not much mixing of water across the equator, Cousins said. It is unclear what the findings mean for human exposure. Inhalation of PFAS is an issue, but how much of the chemicals are breathed in, and air concentrations further from the waves, is still unknown.
