I think there's a powerful incentive to be first, which drives people to research in the face of so much doubt. Trying to convince one lab that the idea is worth funding is hard enough. Two labs is just unrealistic.

My idea hacks around the problem by not diminishing that huge incentive to be first. Even if your paper is retracted due to lack of repro study, you were still the first, and if it does repro you are back to full credit.

I just add an extra incentive to get people who cite the study to verify that its reproducible. And at the same time, give the original author more incentive to include lots of details in their papers so it's more likely to be reproduced, and lock in their fame.
Just because you can insider trade doesn't make something a security in my view. You can do insider trading around gold or palladium or any other commodity for instance. You can do insider trading with property and land. You can even do insider trading with currencies.
Patterns are a pretty normal tool in the work I do. I use Strategy a lot and various forms of Factory on occasion. Others include DTO, Repository, and Specification. Mostly, the libraries and frameworks I use are based on patterns, such as Builder for object initialization, Iterator for collection, and Template for UI development. When I have a new problem to solve and the solution doesn't reveal itself right away, I'll review different patterns to see if there's an approach I haven't thought of.

Sometimes the result is a pure match to the pattern. Other times, I just adapt to something close to a pattern because I'm modeling a real thing and reality often doesn't fit the mold of a pattern in a book. I believe the GOF book acknowledges this so that people will know to be flexible and use Patterns as a tool, rather than an exact prescription.
> The rational actor model assumes that a person will behave optimally - using all information available to make and carry out the best decision possible for their goals.
I strongly suspect that a better model is that people instead of optimizing their outcomes instead optimize the ease of decision making while still getting an acceptable course of action.

This is a very profound insight that I completely agree with. I've noticed that exact phenomena in my own life in my peer groups. Basically disengaging, not looking for new local maximas (in fairness, because they are hard to detect as they are happening) because the current situation is good enough to keep coasting on.
Firstly, accessing an arbitrary list index is O(N), whilst a Zipper can access its focus in O(1) (shifting the focus is O(1) for both Zippers and list+index)

Secondly, using an index forces us to do bounds checks, keep track of the length (or re-calculate it at O(N) cost), etc. whereas a Zipper is "correct by construction"; i.e. every value of type (List[A], A, List[A]) makes sense as a zipper; whereas many values of type (List[A], Nat) don't make sense as zippers; e.g. ([], 42) doesn't make sense. Our logic also becomes easy for pattern-matching, e.g. in Scala:

myZipper match {
case Zipper(xs, x, y::ys) => Zipper(x::xs, y, ys)
case z => z
}

Also, your example of 'list[index-1]' is more complicated than it first appears. In particular, what is the type of 'index'? If it's an integer, then at least half of the possible values are meaningless (negative numbers); if its a natural (AKA unsigned integer), then it's not closed under subtraction (i.e. we have to worry about underflow)!

Thirdly, Zippers can be unbounded in both directions (i.e. the lists can be "infinite"/co-inductive). For example, they're great for implementing Turing machines, starting with an infinite blank tape in both directions. https://en.wikipedia.org/wiki/Coinduction

Fourthly, Zippers have more sharing. Here's an arbitrary example: say we have a zipper like this:

([c, b, a, ...], elem, [x, y, z, ...])

If we shift right, replace the focused element with 'newElem', then shift right again, we'll get this zipper:

([newElem, elem, c, b, a, ...], y, [z, ...])

Those operations take O(1) time and O(1) memory (and produce O(1) garbage, if we're no longer using the old zipper). In particular, since the tails of the lists ([c, b, a, ...] and [z, ...]) are unchanged, the same pointers will appear in both the old and new zippers; there has been no copying. This is important, since those lists could be arbitrarily long (or infinite!).

In contrast, if we did these operations on a list+index, everything before the replaced element would need to be reallocated; i.e. [..., a, b, c, elem, _] would need to be copied, since _ has changed from 'y, z, ...' to 'newElem, z, ...'. That requires O(N) memory allocation, takes O(N) time to do the copying (and produces O(N) garbage, if we don't want the old zipper).

> ...bloom filters... Good use-case: routing. Say you have a list of 1 million IPs that are black listed...

Seems-needed clarification: Bloom filters suffer from false positives, but not false negatives. So - if BloomFilterBlacklistCheck( $IP ) returns false, your router can safely conclude "not blacklisted". But if it returns true, then you'll need to perform further checks. (And you can't just use a Bloom filter of known false positive - that will also suffer from false positive, potentially letting in traffic from blacklisted IPs.)
The government should protect our constitutional rights, provide security from other nations and represent all of us abroad. It shouldn’t build roads, (beachfront) housing, statues or plant trees. Thats up to the people that will benefit from it, whether that be a company, a worker or a town agreeing to do so.

Not really. As a local, I can get by without any aadhaar. He had $1.5m in bank, he could have started his parallel government, or probably for $15m but the fact is that even if you're doing everything by law you don't need aadhaar in India.

>The security on iPhone comes from the app sandbox, not from App Store review.

Some of it. But Apple has the real-world identity of developers/organizations, and will ban them from the App Store for malicious behavior.

And next to no privacy protections are from App Sandbox. You can turn off things like advertising identifiers, but there are a million other unique hardware identifiers as well as things like IP addresses which can be used to track someone.

The way Apple solves this is - you need to get user consent to track, which will also hand you the advertising identifier. But if the user does not consent, you can't work around it by correlating other data from the phone. Or we will kick you out of the store.

> There are lots of scam apps on the App Store, despite Apple's review.

Just imagine how bad it would be without review.

> Apps from 3rd party stores will be sandboxed just like apps from the App Store are today.

Will they? Without someone reviewing/approving entitlements for side-loaded apps, they can all effectively seek out as many entitlements from the menu as they want.

Other people with these requirements may want to look at HP Pro and EliteBooks, if they're willing to put up with dubious screens (they're fairly OK for coding work, I guess).

They're repairable in that HP has repair manuals on their public site, complete with disassembly instructions and part numbers. Never had to replace anything, so I don't know how easy it would be to actually source the parts.

Most importantly, they are also one of the few to have AMD models without any soldered RAM, and they don't insist on HP branded RAM either.

Linux works great on these. The worst I had was an older ProBook whose fingerprint sensor was unsupported. On my current one, it works 100% under Linux, while on Windows I can't get the webcam to work.

There is definitely some proprietary “glue” in there. One nice thing about them is that you pair them to one device and then all of your other iCloud devices can see them. I would not expect that kind of feature to work elsewhere for obvious reasons. I could be wrong?

They also support spatial audio which is now supported with Android.

There are definitely features of the AirPods which are new or were new when they were released. It’s up to Apple to support those features on their own hardware/OS. It’s up to others to add support to their own operating systems if they deem it worthwhile. Similar goes for other hardware. Yes, the hardware works differently than so many generic components out in the world but that’s kind of the point.
What sounds like that?
“The immediate, obvious damage is wasted NIH funding and wasted thinking in the field because people are using these results as a starting point for their own experiments,” says Stanford University neuroscientist Thomas Südhof, a Nobel laureate and expert on Alzheimer’s and related conditions.”

The agency would normally allocate 5% of the budget to management, but Isaac made the decision (since the budget was so small) to completely eliminate that.
The budget ballooned to 6x its planned size and the management allocation was the same percentage of that as of the original budget: 0%.

Rather ironic, since that latter budget probably is sufficiently large not to eliminate management completely. (~$350 vs ~$2000 for mgmt)
I agree in general about the hedonic adjustments and their potential for manipulation or miscalculation. But automobiles are probably the worst example!

Toyota didn't even roll out passenger side airbags until 1998. Only the driver had them prior to this. The new Corolla has 8 airbags. Today we have better fuel efficiency, collision protection, driver assistance, remote start... Even the seats are more comfortable. Not to mention most car brands have much better warranties today than they did in the '90s.

Other things get hedonic adjustments but shouldn't. Shirts for instance.
The main difficulty with growing computing devices in three dimensions is cooling. All that heat has to be somehow carried away. It's already difficult with 2D devices. One would have to incorporate channels for cooling liquids into the design, which takes a bite out of the gains from 3D.

It's just such a waste of time and resources, and it flies in the face of the idea of market efficiencies.

They're not securities because you can insider trade them -- they're securities because they fairly clearly meet the Federal definition;

Tactics and methods surrounding the 2019–2020 Hong Kong protests
Sometimes there isn't much you can do. One I grew up near is a T intersection, between three farm fields. The road that butts into the other crests a hill, and the other road is right behind the crest of that hill, about 20-30 meters. There is a T intersection sign on the hill before you reach the top, but some people didn't see it or heed it. If you're following the speed limit with a dry road, it's probably safe even if you ignore the sign. But if you're speeding and miss the sign, you might t-bone somebody on the other road, or crash into the field behind it. I think the people that died there went into the field, but I'm not sure.

Perhaps they could install some sort of blinking warning light on top of the hill and maybe joyriding teenagers would heed that warning, or maybe not. Otherwise I think you'd have to cut through the hill or move the roads completely, either of which there probably isn't much money for.

> In Sweden, we have made a fantastic sustainability journey; in the 70's over 1000 people died in traffic every year, now there are a few hundred, but still far too many.

https://www.saferresearch.com/index.php/news/210-people-were...

And this is with a very large increase in car use. In Sweden in the ‘30s-40s we had 200-300 deaths/year/100k cars. Today it is 5 deaths/year/100k cars. Cars are safer, newer, better road infrastructure, etc.

In the US there where 42k deaths in road accidents in 2020, with 290 M vehicles. So about 15 deaths/year/vehicle. 200% more. [1]

They can only publish their results, though, they can't force people to accept them.

Any other institution, anywhere else in the world, is free to publish results which disagree.

Scientists should then have the necessary tools to figure out which one is likely to be correct, and try an independent third or fourth time.

It would be expected that sometimes there would be a failure to replicate which was a mistake in how it was replicated, that shouldn't be seen as being a failure of the goal of replication, and the original authors should be incentivized to reach out and discuss the issues with the methods.
You act as if the cited article was simply about an honest presentation of negative results. When in fact it illustrates a similar kind of dishonesty and manipulation as TFA being discussed in this thread.

Your comment has not contributed anything. Which of those many categories do you think crypto falls within?

For example, foreign currency is not a security, and an intuitive stance would be that crypto is far closer to foreign currency than it is to stocks. Other sources have a more useful definition in my opinion [1]:

> Firstly, a security is simply a financial instrument that represents a specific ownership position in either a corporation, a creditor related to a governmental body, a publicly traded corporation, or rights to ownership as represented by an option. The security must represent some type of financial value. Securities are generally categorised as either debts or equities, with a debt security indicating money that has been borrowed and must be repaid.

Under this definition, it is hard to see how the average "boring" cryptocurrency is a security.
