Another factor is initial variance. Russian foxes experiment uses some hundreds of animals, perhaps. Suppose we operate on the scale of millions of specimens, a significant portion of the entire species. There could be a many-sigma difference between the average and the smartest living crow in the world (not sure how to estimate this), but the former one would probably struggle to survive in the city while the latter would thrive. Urbanization, then, can be thought of as a bottleneck that promptly eradicates the left part of the extant distribution, changing the population average even in a single generation.

Integrity (consistency) was the biggest point of relational database theory itself.

> The true importance of relational theory is highlighted by the title of the original (and considerably shorter) version of Codd’s first paper. That version predated the published version by a year, and the title was “Derivability, Redundancy, and Consistency of Relations Stored in Large Data Banks.”[1] The title of this unpublished version emphasizes that the real importance of relational theory is that it provides a rigorous method of asserting arbitrarily complex consistency constraints that must be satisfied by the data within the database.

Catching a fraudster is a delicate combination of not them working hard enough to fake the data, close scrutiny (why would a study be subjected to abnormally close scrutiny?), and many other factors. It is also worth mentioning that failed replications do not necessarily lead to retractions - in fact, in most cases (of an honest mistake or an unlucky sampling) retracting the original paper wouldn't make any sense. Finally, not all retractions involve fraud, for example mathematicians will issue retractions when mistakes are pointed out.

For these reasons, retractions are not a good measure of behavior.
How about: it’s the responsibility of people posting ads on Facebook to follow the laws that apply to them.

I don’t see why it’s Facebook’s responsibility to police advertising for housing and control how it’s targeted. If advertisers use illegal targeting then that should be on them.

So you claim that democrats do believe in helping the homeless, unlike republicans. Doesn’t that imply that the Democrats who have ruled San Francisco for the last 40 or more years are grossly incompetent?
True. However, if your comment about is about gender, that would only be true if you think that women are less likely than men to get caught falsifying data (there was differential detection by gender). I can't imagine why that would be the case.

Edit: this was in response to your comment before your edit

I agree retractions are an imperfect measure, but it's not like there is much more to go on.

Most importantly, the 30 people on this leaderboard who have dozens of retracted papers are not just people who got unlucky with sampling or made one mistake and had to retract a paper–they are those who repeatedly and knowingly faked data and then published it.
“Other manufacturers have onsite repair” who does that nowadays and how accessible are their stores?

I’ve had friends with HP, Dell, etc, laptops ship them off and wait a week to hear what is wrong and give them an estimate. And they usually had to ship it themselves. I had an Apple repair and it took less than a week with virtual no wait right by my house.

Say what you will about their keyboard problems but people were envious of my repair experience.
Not a year goes by I don’t kick myself for getting rid of my HP 28s. It wasn’t from the same era as those in the article but damn, what a trusty work horse it was for me in college.
You could combine these ideas, though, and have only a few cars that pull weights up/down the hill, with a crane to load it off. I'm not sure but it could probably allow for a far greater total storage and kWh/$.

Before I started Optic I watched 20 developers code for 1 day each. I kept logs of what they were working on and asked people to rate how they felt throughout the process. The 15/hrs/wk is a rough estimate of what we could automate. Our most avid users over the last month self report a little less but I think once we add better support for a few more things we’ll catch up.

I never thought to publish those results. Sounds like something people would be interested in?
Well the guy was an accomplished developer so... no need to move the goalposts.

Grass fed organic meat will solve all of our problems right?

Except for the fact that it is too expensive for most to afford, meaning only the upper class can eat the stuff and feel good about it; also it produces much more methane per pound of meat than the corn-fed and hormone-injected equivalent; and finally it requires MUCH more space -- space that could be used for more sustainable agriculture like soy farms or chicken factories.

Environmentally and economically it seems like America should be engineering it's meat. Ethically, this is a different story, especially with the torturing of animals that often accompanies this meat engineering process.

The reason that I personally stand behind the development of meat alternatives like the impossible, and cultured meat, is that these are attempts to continue increasing the environmental and economic viability of meat while simultneously eliminating the ethical issues completely.

Yes the alternative meat field is young and not effective right now, but that's no reason to abandon all hope that cheap sustainable meat-like sustenance is possible. Impossible should be lauded and encouraged to improve their product. Their very name is a clue that what they are trying to do is not easy, but I think if successful, it could pay off big for society.
Haha, I recently bought the HP-12C and the HP-50g mainly just to own them.
How can a falling block generate electricity? Is it like a turbine that spins very slowly as the block falls?
Are vitamins actually useful? The vast majority of people who eat normally don’t need vitamin supplements. It’s all mostly scammy to me: selling people a product that has almost no value unless you are malnourished. It’s big business sure, but it’s on the level of homeopathy for most people. Providing vitamins to undernourished kids might be valuable, but there isn’t any money in that. Vitamins are right up there with “organic” in terms of quantifiable health benefits.
> Once you have one solution you can find others by applying the transformation.

Interesting. That sounds like roughly the inverse of what I was trying to describe: using the transformations to generate rather than analyze.

That's pretty cool though. If I understand correctly, the process would be something like: prove that an equation has some symmetries[0]; then find one solution; then, since we know the equation's symmetries, we can use them to gain access to a formal expression of all the solutions, which could then be used (for example) to assert that such and such must be in the solution set or not in the solution set, etc. (actually, bad example there since our original equation already allows us to do that...)

If that's right, then there's probably some way of making reference to the symmetry groups algebraically—maybe that's part of what the U(1) etc. notations are for? And then some way of getting a symbol meaning essentially, "group X applied to entity Y", where entity Y is something like a solution to an equation with the appropriate symmetries, and group X is a symbol for the symmetry group like U(1)? Or maybe "entity Y" is the symmetric equation rather than a solution.

My initial thinking was more like that you'd start with something symmetric like the full set of solutions, then use knowledge of the symmetry to eliminate repetitions, so that you're only left with what's unique and can analyze that in isolation. But I guess that would make more sense to apply to observational data rather than to a set of solutions.

Using the electrodynamics example: maybe you'd start with a bunch of recorded data related to electric and magnetic phenomena interacting, which in some sense is like a sampling of the solutions to (ideally not yet discovered) equations describing electrodynamics. So if you could determine that that data has some symmetries, you can use it to eliminate everything that's repeated, and what's left (a single solution I suppose...) might given you some insight about an equation which would have it as a solution.

[0] When it's said that "an equation has a symmetry" is it just shorthand for "the solutions to an equation have a symmetry"?

Cattle naturally eat grass, in a symbiotic relationship with the grasslands.

Joel Salatin, legendary proprietor of Polyface Farms, considers himself a "grass farmer". He maintains the grassland, which the cattle graze on and perform several important functions. Not only does grazing stimulate root growth, but the cow digests cellulose (or technically, the bacteria in her rumen ferment it) and emits fertilizer, feeding the plants ever hungry for more nitrogen and predigested nutrients. Grass uniquely grows from its base instead of its tips, so the cows eating and grazing on grass doesn't kill the plant, but rather the opposite.

Contrast with other plants with thorns or spines or chemical deterrents (such as coffee, caffeine originally a pesticide generated by the plant to deter predators, now cultivated by humans as a stimulant) or anti-nutrients or toxins. Grass has none of these. Lierre Keith explains in her usually floral prose how grasses want to be grazed, metaphorically: the grass created the cows (a similar point can be made about human domestication and lactose tolerance gene).

Of course, concentrated animal feed operations additionally feed cattle with grains. Grains are a recent invention on the evolutionary timescale: they didn't exist until humans domesticated annual grasses about 12,000 years ago, whereas the progenitors of the domestic cow, the aurochs, were around more than 2 million years ago. Cattle aren't adapted for grain, upsetting the delicate balance bacterial balance of their rumen, causing sickness. Poultry fed too much grain will develop fatty liver. So why do it?

Grains are cheap, very cheap. An ideal commodity, storable and portable. A dense organic form of energy, most likely converted from fossil fuel fertilizer thanks to Fritz Haber. And they cause explosive growth in animals, dramatically increasing both meat and milk production. The economic incentives are there.

That doesn't mean it is a good idea, or is sustainable or ecologically wise or nutritionally healthy.

Fortunately, grassfed grass-finished pastured beef is getting easier and easier to find. Thousands of years ago, used to be the only kind there was, now we are coming back full circle.

Einstein's annus mirabilis ("miracle year") in 1905 involved publishing 4 excellent papers, covering some very different ideas: the photoelectric effect, brownian motion, mass-energy equivalence, and special relativity. It's true that he later focused on relativity, but the photoelectric effect and brownian motion are still quite different.
Coworker approached me during lunch and pitched me the startup he was about to co-found. He told me I am the most talented but the most undervalued engineer there. He shows me the slide deck and says: “Help me build this. We will get the funding. And the job is yours.” That was 4 yrs ago and I am glad I said yes. To be honest, this was burning the candle at both ends. I slept on the floor of the cowork space conference room to make this happen.

It seems you're missing the point. React and Mithril both employ virtual DOM, both use components and both allow higher abstractions that provide ways to manage complexities that arise in front-end development. Jquery and HTML don't do that.

I tried both Mithril and React and found Mithril to be simpler than React as it 'gets out of the way'.

Here I have to disagree (in the small) essentially the problem of 'breaking' a RNG is discovering that hidden state (the entropy pool) behind the CSPRNG - if you believe that the NSA, and their competitors, don't each have a team of PhDs pouring over the linux random code looking for ways to do that you're dreaming. After all if you know its state you can predict the keys it will make in the future

My intuition is that every operation we do (start TCP connections, generate keys, backoff after a failed login, ....) reveals a tiny fraction of a bit about that hidden state, web assembly calling random over and over again probably reveals much much more, over time it builds up.

(anyone want to guess if there's a quantum computer attack here, it kind of looks like the sort of problem where there might be)

So I think that with a sophisticated enough attacker entropy does degrade, the trick is to replace that entropy at a faster rate that the rate at which you guess the worst case attacker might be able to guess.

For most people it probably doesn't matter, you're exposing so little state over time you're likely effectively as safe as the parent poster claims, it kind of depends on whether, in this age when we know that nation state actors are watching every packet that passes thru their hands, watching every thing we're doing online, are you interesting enough for them to spend the time and effort? does the US/5Is think you're not a Trump supporter? are the Chinese interested in your trade secrets? whi knows what the Russians think

As I mentioned above using /dev/urandom doesn't have a mechanism you can use to signal this guess about how much entropy it needs over time to be safe, prior to 4.8 we used to have a mechanism that said "give it some more entropy every N seconds, 60 by default" but that's now broken

(provided here a python applet that periodically drains a little bit of /dev/random entropy if it has plenty available to stir the input pool that /dev/urandom uses for its entropy source)
This is the maximalist approach. However, you probably do lots of other things which have not been tested by history eg using mobile phones.

Also bear in my mind the way which our ancestors ate meat is very different to how we do it, and there is much evidence that red meat consumption is bad for your health in the modern context with our long lifespans.

To be honest, it is very confusing to try and work out what constitutes a healthy diet these days.

Retractions aren't issued just for falsifying data. Each field has its own culture of retracting papers, some only retracting deliberate fraud (each one with a different standard of evidence), and others retracting mistakes as well. It is also well-known that certain countries contribute more than others to scientific fraud - and it would be unlikely for them to all have exactly the same gender ratio. By the time all of these factors (along with whatever else can be thought of) are included there might be a lot less statistical significance left than we started with.
I know they are people. Why do you think otherwise? Don't you think about people when you read "homeless"? Makes me wonder, since you so strongly react to it.

Ask HN: Convolutional VS Recurrent/LSTM/GRU neural networks
Many research found that Convolutional neural networks can reach near the state of art of Recurrent/LSTM/GRU neural networks ON many NLP/Audio process tasks, but with several times training speedup and less memory usage, then why we still use RNN? RNN should have more power on NLP/Audio, but too slow, maybe it has many incredible power we can't explore now, maybe it can reach near human intelligent in the future with more powerful computer power, in that future RNN maybe rediscover and revival like neural network now by DNN, but now can we just use CNN for nearly every thing in real product, no slow RNN?

I have not much personal experience with OOP either.. but have seen 'Fluent Python' recommended a lot for this..
The western variant does not necessarily save the driver only half the weight, this depends on how the wheelbarrow is loaded. In the standard arrangement, with handles extending out towards the driver, and the wheelbarrow tipping forwards forcing most of the weight to the front, I could see 3/4 of the weight being offloaded to the wheel. While it still loses to the chinese variant, the trade off is that the "barrow" portion of the wheelbarrow can carry loose items, including dirt or even water, whereas the chinese design requires items to be in bags, which are then tied down. Also, anyone who has ever driven a well loaded wheelbarrow knows that they have a considerable danger of tipping, and I think this would be accentuated in the chinese design. Placing most of the weight near the axle between the wheel and the ground means that any slight tendency towards one side (say by an imbalance while loading, or a bump in the road) is more easily corrected for in the western design.

I wonder if we might liken this to the distinction between the chinese preference for energy saving and the british preference for labour saving, as recorded during the industrial revolution. A chinese wheelbarrow will require much more time to load, and will require more care on behalf of the driver to prevent it tipping, but will require less energy of them. The western variant can be loaded quickly (perhaps with a shovel), but requires the driver to bear some portion of the weight, and thereby use more energy.
Each 35MWh system requires about 1.62 acres of land. That seems perfectly reasonable to me, especially since there are still optimizations to explore.

Here's some totally useless back-of-the-envelope calculations on land requirements for this sytem.

The United States, in total, used 1,819,393,805 MWh of energy in 2016. If one plant provides 35MWh of storage, that means 51,982,680 plants are required.

That comes to 84,211,942 acres of land. There are 2.3 billion acres of land in the United States, so it would require 3.66% of the US. That's obviously a huge overestimate.

The beauty of this is the simplicity. This is something we could have built 40 years ago. And unlike LIBs, there's much less worry about degradation and we can put these out in the desert near a solar power source without worry.

Imagine it combined with solar thermal, which has dropped immensely in price per KWh.

Also, concrete reabsorbs around 43% of the co2 used to create it over a period of time.

The cost is key here though, at $2m or potentially lower you're paying just $1-2k per home and maybe $100 a year maintenance thereafter. Not a bad price overall for what you get. In Australia at least, electricity costs $1-2k per year per household. Some napkin maths tells me that at 15MWH consumption per year this sort of storage could make solar (at $50 per MWH) pretty viable. As in, potentially below $1k per year even if you build enough storage to cover 80% of the day.
I’ve heard mathematicians express similar reasons for studying math. It can be something of a universal language.

Personally, I think no matter how often matter-energy arrange themselves into life in the universe life remains vanishingly rare. For that reason, life should be as harmonious with itself as possible - diverse and varied but self supporting. The rest of the universe is rarely calm and stable enough for life to exist.

As for why we haven’t found life yet: we are very new to this game. We just in this last decade started being able to resolve properties of exoplanets. I don’t think we have the information to even posit a question like the Fermi paradox with any level of confidence.
