Comment Mars is still the goal (Score 1) 70

The Moon is target practice. We need to get away from innovative bespoke engineering, into industrial mass production with continuous improvement. To do that we need to fly often. Mars just doesn't have the launch window availability. The biggest part of the challenge is that we were born in the bottom of a deep well. To toss enough stuff out of the well for a long journey is critical. Boosters that reliably fly on time often and cheaply enough to get ships and fuel out of the well. Ships that carry fuel into orbit and return over and over since the vast majority of the material we need to send out of the well isn't payloads or ships, it's fuel. Kilotons of fuel. Once the factories and processes are set up for that going far beyond the Moon is fairly easy. But with a narrow opportunity every two years that's not going to happen in a human lifespan. It's not enough refinement cycles per year.

I see this accelerating the Mars objective, not deferring it.

One of the lessons we've had as the Federal, multi-branch nature of the US governmennt has frustrated Trump is that the government may be fucking us over, but it's not doing it in *unison*. It's doing it piecemiel, on the initiative of many interests working against each other, just as the framers intended. The motto on the Great Seal notwithstanding, there are myriad roadblocks to consolidating power in the hands of a single individual. It takes time and repeated failures. This is why the second Trump Adminsitration is worse than the first; they've figured out ways around things like Congressional power of the purse, put more of their henchmen in the judiciary, and normalized Congress lying down and letting the president walk all over them. It's a serious situation, although fortunately Trump isn't long for this world.

While that's true, a responsible generation aims to boost the next generation to a *higher* level than the education they received. The world has become more complex and faster-paced, and even if that weren't true, the consequenes of aiming high and falling short are better than the consequences of aiming for the status quo and falling short.

So while I'm 100% onboard with skepticism that technology will magically make education better, I think the argument that "the education I got worked for me should be good for them" isn't a strong argument. What we need is a better ecducation that would have been a better education fifty years ago: stronger math, science, and language skills, general knowledge, and, I think critical thinking and media literacy. Possibly emotional intelligence -- it's kind of pointless to teach people critcial thinking skills if they are carried away by emotions.

There are no economic or security reasons to blockade Cuba, so that leaves *political*.

It used to be believed that bullies were low status individuals who are lashing out out of frustration. But research has shown that bullying is an effective strategy for achieving and maintaining social status. In other words it's a political winner. So the focus of research has shifted from the bully to the people around him who enable the bullying. The inner circle are the henchmen -- people without the charisma and daring to initiate the bullying, but join in when the bully gets things started. Around them are the audience, the people who wouldn't risk participating but enjoy the bullying vicariously. And around them are the much larger group of bystanders, who don't approve but are waiting for someone else to stop the bullying. Then off to the side are the defenders, who stand up to the bully.

Perhaps the least appreciated supporting factor in the phenomenon of the high-status bully is the silence of the bystanders, which is dependent upon the perception of widespread approval. Since you can't visibly see the the line between the approving audience and the apalled bystanders, the silence of the bytstanders is absolutely essential in sustaining the bullying.

Lot's of Americans are apalled at the idea of using military force to inflict suffering on the Cuban people. But that's only politically advantageous *because* of *them*. Tney are indistinguishable from the relatively small number of people who are thrilled when Trump announced he can do anything he wants wtih Cuba. The gap between actual approval and *perceived* approval is absolutely critical in establishign and maintaining any kind of authoritarianism. This is why would be authoritarian leaders are so focused on punishing and marginalizing any kind of expression of disapproval.

Submission + - Ryugu asteroid samples contain all DNA and RNA building blocks

symbolset writes: More and more science is pushing back the Drake equation, reducing the parameters necessary for life to form. From the discovery that organic molecules are formed in the little red dot protogalaxies at the edge of our visible universe to AI models that identify a self replicating RNA molecule in only 45 nucleotides. Now comes Toshiki Koga et al with a study published in the journal Nature Astronomy reported on by phys.org finding all the nucleobases of RNA and DNA in pristine samples collected from the asteroid Ryugu. The bases being uracil adenine, guanine, cytosine and thymine. Ammonia was also found.

The universe it seems is made of soup.

Comment Re:Helium can be re-used? (Score 4, Interesting) 125

Is joke of course. Was angling for the same joke.

3He is normal helium atom with an extra neutron, hoped to be used in some forms of fusion. It's not considered radioactive. Emitted by the sun it's trapped in lunar rock possibly at concentrations of up to 50 parts per billion but more likely 5-10ppb. The utility of extracting it from the Moon is hotly debated. On Earth isolating it from normal helium involves the same sort of centrifuge used to isolate isotopes of uranium, radium, hydrogen but there is far less of it than in lunar soil.

This is not actually the case in the subject at hand. It's all normal helium. When cooled enough all other gases will precipitate out as they freeze - including Hydrogen - leaving only helium as a gas and so easily isolated. That's actually why it's valuable since it's the only gas that will boil off at temperatures so low that the conductors immersed in the fluid will superconduct supporting the currents necessary for the intense electromagnets used in imaging and such. /Explaining nerd jokes since 1983

In 1790, the US population was 94.9% rural. There is no country. in the world today that rural -- Burundi, which looks like blanks spot in the world at night satellite picturs, is 88% rural.

The largest city at the time was New York, with a population of 33,000. Northern Manhattan was near-wilderness, mid-town was farms and country houses.

In 1790 the US was. country you could "police" with sheriffs and volunteer posses, largely to keep the peace. If you got robbed, you hired a private thief catcher. This works in a 95% rural country with just 3.4 million inhabitants. It would be chaos in a country 87x larger.

It's actually more like an iPhone 16 Pro runing MacOS in a laptop form factor. Apple basically rummaged through their parts box and pulled out a mobile CPU that'll deliver 50% more single core performance than what's in a high-end Chromebook with only 80% of the power draw. And Apple's got *massive* economies of scale on those parts, so they can afford to deliver a lot of bang for the buck.

The only place the Neo appears to falls short is in RAM, but this is *not* a power user machine, it's for basic office tasks and multimedia consumption. Realistically 8GB is plenty for many users.

In any case, the desktop isn't the center of most users's universe anymore; the switchboard of their life is their smartphone. This is a gateway drug to MacOS IOS integration, and eventually onto the upgrade treadmill. Users will switch seamlewssly between their iPhones and Neos all day long, with data on iCloud and iMusic etc., and when it comes time to upgrade their phone or their laptop, they won't be *stuck* exactly, but if they leave the reservation they lose a lot. But they certainly could upgrade to a *much nicer* Macbook....

It's no wonder the other laptop makers are sitting up and taking notice. Apple has set up a one way conversion ratchet for people tempted by a really nice and perfectly adequate entry level machine at an entry level price.Nobody else has the vertical integration -- chip foundries to device manufacturing, to software platform -- spanning desktop and phones that's needed to do this.

Choose your adventure books are AWESOME. I had a time travel one that I probably worked my way through a hundred times, always coming up with different scenarios. It was like training wheels for the imagination, with just enough guidance to keep you from spiraling out of control, but still let you stretch.

There was one called Inside UFO 54-40 that had an ending you couldn't navigate to. You had to "cheat" to find it, by just reading a section of the book that you had no way to reach. I thought that was pretty clever.

Similarly, Infocom had a text adventure game called The Lurking Horror that needed you to enter a computer password at some point to continue with the game. The password was only provided in the physical materials included with the purchased copy of the game. But if you knew how to hack into the game binaries, the password was actually there -- multiple times -- in plaintext. That had to be intentional.

The same business as any other police officer has in arresting (and shooting, if they feel threatened) people who interfere with their duties.

Except ICE isn't ordinary police. They're described as law enforcement officers, but their jurisdiction encompasses only a very small range of laws, related to immigration and customs (hence the name). Plugging multiple rounds into U.S. citizens who piss them off for some reason is not within their mandate.
