I wrote "makes 12 years old learn the math" not to imply KSP teaches math by itself, but to observe that it motivates kids to go and learn the math on their own, and to enjoy it.

If you take a look at the community around KSP, you'll find plenty of kids learning math and physics to better understand what their spacecrafts are doing and how to make better ones.

Reminds me of how I learned trigonometry myself - I hated it at school, but learned it immediately - along with basic matrix/vector linear algebra - once I needed it to rotate stuff in a game I was writing.

This brings me to my core issue with edutainment - fake problems. Bite-sized issues designed to "teach" a kid a particular concept, which can be immediately recognized for what they are - school after school. Fake problems are not fun. Meaningful problems - those working within the context of a game world that stands on its own, like "wtf is ∆v, how does it work and how do I ballpark the amount of it in my rocket" - those are fun and motivating.
In addition to what others have said, during the Cold War there was a concern that the Soviets would freak out if they saw any unexpected rocket launches. Early rockets in particular were just souped up ICBMs
Is that mainly what you have found fills that time? Or have you found other uses for it?

Not all of my time is wasted on Reddit/HN. I actually have quite a few high-quality subs I subscribe to, and in general I learn quite a bit each day on both places from the comments. Sure there is room to cut back, but there is definitely some strong "signal in the noise."

I have felt a lack of creative energy these past few years, so I wonder if that would start to come back, but I genuinely can't picture what I'd do without those things in my life. It is very sad when I think about it, but I wonder if there is a happy middle-ground vs. going all out with a dumb phone.
>Failure to separate is almost certaionly on SpaceX.

One thing to note here, the payload adapter was made by Northrop Grumman instead of SpaceX. If the payload adapter itself failed then that's not on SpaceX even though normally the payload adapter is something that they provide.
Maybe more than half. ;-)

I think that the branch aspect of Spectre is the thing that WebKit is most affected by.
> Naysayers would point out that trading increases liquidity which ostensibly increases the ability of a market to parlay information into value.

And increasing opioid supplies, increases the ability of the market to efficiently parlay money into an altered mental state. Doesn't mean it's a net positive for society.

The "liquidity" argument is such a terrible and simplistic justification for so many things.
And what happens when advertisers realize that they, too, are obviously not going to sell anything to these users ? I mean, isn't this exploiting the market ? (perhaps for a "good" cause but that's a matter of opinion)
I guess we'll deduce the outcome from whether SpaceX will get further similar contracts.
The law doesn't care how stupid your plan was. You could plan a theft in the middle of the day stealing $5 and still be a crime

Insider trading is trading with the knowledge of privileged information not available to public investors. If he did it, it's a crime. Doesn't matter if he made $50 million or $5.
With a shared cache.
I find several references as I read the article:

"In Persuasive Technology, one of the most quietly influential books to come out of Silicon Valley in the past two decades, the Stanford psychologist B.J. Fogg predicted that computers could and would take massive advantage of our susceptibility to prodding. "People get tired of saying no; everyone has a moment of weakness when it's easier to comply than to resist," he wrote. Published in 2002, Prof. Fogg's book now seems eerily prescient."

"A recent study of Chinese middle schoolers found something similar. Among more than 7,000 students, mobile phone ownership was found to be "significantly associated" with levels of inattention seen in people with attention-deficit disorder."

"Workers at a British company who multitasked on electronic media – a decent proxy for frequent smartphone use – were found in a 2014 study to lose about the same quantity of IQ as people who had smoked cannabis or lost a night's sleep."

This item cites expertise rather than a specific study, but:

"These companies have persuaded us to give over so much of our lives by exploiting a handful of human frailties. One of them is called novelty bias. It means our brains are suckers for the new. As the McGill neuroscientist Daniel Levitin explains, we're wired this way to survive."

"The devices exert such a magnetic pull on our minds that just the effort of resisting the temptation to look at them seems to take a toll on our mental performance. That's what Adrian Ward and his colleagues at the University of Texas business school found in an experiment last year. They had three groups of people take a test that required their full concentration. One group had their phones face down on the table, one had them in their bags or pockets and the last group left them in another room. None of the test-takers were allowed to check their devices during the test. But even so, the closer at hand the phones were, the worse the groups performed."

"Researchers at Cambridge University showed recently that eye contact synchronizes the brainwaves of infant and parent, which helps with communication and learning. Meeting each other's gaze, Ms. Sandink says, amounts to "a silent language between the baby and the mom." That doesn't mean breastfeeding mothers need to lock eyes with their children 24 hours a day. But while Ms. Sandink emphasizes that she isn't trying to shame women, she worries that texting moms may be missing out on vital bonding time with their babies."

"Catherine Steiner-Adair, a clinical psychologist and research associate in psychiatry at Harvard Medical School, interviewed 1,000 kids between the ages of 4 and 18 for her 2013 book The Big Disconnect. Many of them said they no longer run to the door to greet their parents because the adults are so often on their phones when they get home."

"The Center for the Digital Future, an American think tank, found that between 2006 and 2011, the average number of hours American families spent together per month dropped by nearly a third, from 26 to about 18."

So, no, actually, I find your characterisation entirely inaccurate.
>To be clear, you're trying to blame Obama for something the Republican controlled Congress was responsible for?

No, he's blaming Obama for something the Democrat controlled Congress was responsible for. It was an important enough issue for him to cosponsor a bill while a senator, but while in control they let a bill die without debate.
> "We do not comment on missions of this nature"

...but we'll happily take their money. Maybe I am too much of an idealist but it disappoints me that the greater goals of SpaceX are being partly funded by 'dark dollars'.

I'd much prefer that they left that money on the table and just worked with commercial contracts, instead of associating with the sort of agencies that need secret launches.
Miners find a block and distribute them to the P2P Bitcoin network. Blocks do not carry IP addresses, and everyone running a Bitcoin node contributes to sharing blocks, so you'd have a hard time finding out who is mining just from the IP.

If the Chinese miners are using a public mining pool, you may be able to see who is connected to the pool. If they're pool mining, they do not even have to run a Bitcoin node in the first place.
Using Machine Learning to Predict the Value of Bitcoin
Efficient market hypothesis

That's a kind of ideological way to phrase the situation. It's easier to just describe the "stable market hypothesis"; however things are organized is the way that market structures have stably gone and thus can't easily be changed (whether market are efficient or not). This includes all the points in the parent plus the point that you may have improved on app/gimzo X significantly over the weekend but the market probably still won't jump to your solution easily because of mind-share/network-effect/existing-investment/market-leader's-connection-to-customers/etc.
It's a very uncharitable definition, sure.

There's no organisation, recruiting, directors, membership or promise of payments.

But those definitely exist, just not via any singular organization. There very much is organization and organizations, recruiting, would be directors, unofficial membership in the club of ownership, and lots of promises of payments.

When people make that comparison, what they're really saying is Bitcoin is mostly funny money which above all else has enriched early adopters and will probably lose a lot of late adopters lots of money. It's ceased to even be a useful currency.

You don't have to squint very hard to see the comparison, even if it isn't flattering or technically the same thing as a pyramid scheme. This is from your link:

In a pyramid scheme [Bitcoin], an organization compels individuals who wish to join to make a payment [purchase Bitcoin]. In exchange, the organization promises its new members a share of the money taken from every additional member that they recruit [to the moon]. The directors of the organization (those at the top of the pyramid) also receive a share of these payments. For the directors, the scheme is potentially lucrative—whether or not they do any work, the organization's membership has a strong incentive to continue recruiting and funneling money to the top of the pyramid.

Such organizations seldom involve sales of products or services with value. Without creating any goods or services, the only revenue streams for the scheme are recruiting more members or soliciting more money from current members. The behavior of pyramid schemes follows the mathematics concerning exponential growth quite closely. Each level of the pyramid is much larger than the one before it. For a pyramid scheme to make money for everyone who enrolls in it, it would have to expand indefinitely. This is not possible because the population of Earth is finite. When the scheme inevitably runs out of new recruits, lacking other sources of revenue, it collapses. Because in a geometric series, the biggest terms are at the end, most people will be in the lower levels of the pyramid (and indeed the bottom level is always the biggest single layer).

In a pyramid scheme, people in the upper layers typically profit while people in the lower layers typically lose money. Since at any given time, most of the members in the scheme are at the bottom, most participants in a pyramid scheme will not make any money. In particular, when the scheme collapses, most members will be in the bottom layers and thus will not have any opportunity to profit from the scheme, yet they will have paid to join the scheme. Therefore, a pyramid scheme is characterized by a few people (including the creators of the scheme) making large amounts of money, while most who join the scheme lose money. For this reason, they are considered scams.[2]

Sounds like many cryptocurrencies and Bitcoin is approaching that if it hasn't hit it already.
I have no problem with valid criticism of cryptocurrency, and especially of its fanatics, but I’d be curious to hear you back up your claim that at best it’s a zero-sum game. That seems to me to be clearly incorrect.
I've had a miserable love-hate relationship with Google Voice for years, what do you mean by "the latest iteration of Google Voice has chat?"
Another alternative is a camera with some sort of networking / offloading capability.

In the pre-smartphone era I picked up a pocketable digital camera, and it remains the device on which I've shot my best images. Having a camera with you, and a small tripod (I've several that fit into a jacket pocket or bag) makes for excellent results. Losing the distractions of the phone is a plus.

I always liked the https://en.wikipedia.org/wiki/J%E2%80%93Machine idea: gobs of processors each with a small private memory (nothing shared), in a fast mesh network. It fits with physics: accessing local memory can be fast, while distant memory physically just can't. But even if it's really all that, it's just so different from the architectures we've put so much work into or on top of.

The business of improving global health
Sorry, I have no recollection of how much I paid. That was a long time ago. It's definitely true that devices are ridiculously cheaper today. I paid >$1000 in 1980 dollars for an Apple ][. Today you can get a Raspberry Pi Zero for $5. I also don't think that the hardware is that much less durable. I have an iPhone 4S that is still going strong. The real problem IMO is not that things are less reliable, but that they're built to be disposable rather than repairable and upgradeable.

I use the multiplier the other way around. When I am about to spend $100, I remember it’s about $150-160 in earned money.
Yes, well, close.

It is good to get talking about mental health with other mentally ill people and psychiatrists as well.

I used to do that on Kuro5hin, but it went down, I used to do that on Reddit but got banned from some subreddits with no feedback given.

I have websites I am working on to develop into organization etc.

I have a keybase but haven't used it much. I don't have many friends, many reject me for my mental illness, and I am not allowed to talk about it in public areas of the Internet.

For some reason, I get along with people who have autism because I have social issues like they do, and might be misdiagnosed, but still I might have been on the spectrum before the changes got made.

Yeah, it is unpopular to discuss mental health or politics on the Internet. Rather than ban the people attacking the mentally ill person, they find it easier to just fire the mentally ill person from work or ban and censor them on the Internet etc.

I'd like to do some sort of non-profit that helps mentally ill people find work or start up their own businesses.

Ok, I'll concede that calling it force feeding is a bit tabloid, but the end result I described is undisputed - ad libitum feeding results in obesity in the control animals. Which indisputably muddies the waters for the results, since you don't know whether CR extends lifespans or AL feeding shortens lifespans in these animals.

The dog study you link also highlights another issue with this kind of research: they focus on osteoarthritis, i.e. cartilege in joints being worn out over time, since that was the most common chronic disease. This occurred equally often in both groups, but time until first treatment for this condition was 25% longer in the CR group. That's exactly what you expect just from the 25% reduced body mass of CR fed dogs which they report, since reduced body mass puts less stress on the joints. No attempt is made to account for this, it is not even mentioned as a confounding variable.

Taken together with the fact that they don't observe any significant increase in maximum lifespan of the CR fed dogs, it's again very unclear whether this is anything more than confirming the well-established result that when you inevitably get a chronic disease, higher body mass means you get sick faster.

We carry supercomputers in our pockets for the primary purpose of broadcasting pictures of food we are about to eat. If that's not wildy futuristic (and perhaps a bit dystopian), I'm not sure what is.
It's common for C++ code to do type checking dynamically. In WebKit we do this by rolling the type checks ourselves. With RTTI, you can do dynamic type checks using the build-in dynamic_cast primitive. Our changes, particularly the ones having to do with pointer poisoning, are meant to protect C++ code that does dynamic type checks in addition to JIT'd JS code that does dynamic type checks.

Rust's `match` statement is a dynamic type check just like C++'s `dynamic_cast`. I bet you it's implemented using branches.

I mean, even if you follow all policies and laws, and treat people according to the prevailing wisdom/popular opinion - you're more likely than not to be fired for voicing an opinion which is contrary to it - even more so if your opinion leaks out of the company.

From twitter, Dr Marco Langbroek:

I have the feeling that this whole story about the failure is a textbook case of misinformation, which is understandable since Musk has mentioned that this is "the most important mission (that SpaceX has undertaken)" and that it's all very heavily classified..

> In a pyramid scheme [Bitcoin], an organization compels individuals who wish to join to make a payment [purchase Bitcoin]. In exchange, the organization promises its new members a share of the money taken from every additional member that they recruit [to the moon].

There is no such thing. In that respect, Bitcoin is no different from real estate, stock or gold investors which do tend to sometimes promote their investment of choice. Pyramid scheme has a precise definition which does not fit Bitcoin at all and using it to describe Bitcoin is just misleading and intellectually dishonest. If it was a pyramid scheme, it would be deemed illegal in many, many countries. I agree with one thing however: as with every single investment ever, early adopters, which take on more risk, stand to profit more than late adopters.

Their CEO has a well-documented six-year history of acquiring and disposing INTC stock. As the CEO, he implicitly always has access to privileged information. How exactly does the SEC determine the legality of a specific trade?

I'm not trying to be flip here, I don't really have an opinion on the matter. It just seems that when the CEO is allowed to apparently buy/sell as they please, and not on a predetermined announced-in-advance plan, you could argue that every single trade was illegal insider trading.
Sigh. The only sense in which it "solves" the Two Generals Problem is the sense in which it will, over the course of decades, create a rainbow table for it. None of the work being done is in any way socially useful (a crypto coin based on, say, folding proteins actually produces a social good and so could be equity based).

Decentralized proof of a transaction having occurred is in principle valuable, but the token itself is not the store of value. The reason it is accurately described as a pyramid scheme is because holding bitcoin for the purpose of reselling it is exactly like holding a baseball card, or a share in Bernie Madoff's hedge fund: it is based on the premise that someone will come along and pay you more for it than you paid, despite no actual appreciation in any fundamental value.
