Without doing further research, what are some ways that the laws could have evolved in this direction? I practically guarantee that for each idea you will be able to find a municipality that tried it and found that it didn't work for w

This article is very vague in its accusations. What, exactly, is the scam? It looks like the article is saying that companies involved in plastic production pushed for more recycling, while knowing that current plastic recycling capacity wa

Even with this explanation a 64 + 48*4 is clearly superior. You can go longer without overflow (since you have 16 bits of carry space per pseudo-digit), and the amount of carry space is aligned even more nicely.

I do think you've hit the heart of the question, but I don't think we can answer the second question. We can measure how unreliable they are, or how susceptible they are to specific changes, just because we can reset them to the s

A lot of money in craps gets bet on odds that are close to even-money. It's hard, I think, to weight dice so that the house would increase their take by a measurable amount. A lot of the effective value of a casino is gamblers ruin --

Although I skimmed the methodology out of curiosity, what really drew my eye was the transcription in the repository of the manuscript. This led me down a rabbit hole leading here [1] about historic efforts to transcript or transliterate th

The article cuts off for me so I do not know if they talk about this, but preregistration has to be part of the conversation moving forward. And it has to have teeth -- withdrawn studies have to have a reputational risk that affects the cre

As long as there is transparency about the process, I think this sort of thing is basically fine. It's roughly at the level of observational science rather than experimental science, and it can help lead to new research to validate the

These flows all feel very dangerous to me because they potentially allow a site to access information about me that I have not explicitly allowed. Take the web hosting example; naively if I visit any site hosted by that company, can they de

Cases 1 & 2 are manageable through url parameters since there is shared infrastructure on both ends. These can be done without any user visible workflow changes. Case 3 feels the most like a legitimate use case. Even with url parameters

Not with off the shelf protocols. Yes WPA3 is plenty secure, but any AP advertising the same SSID with the same key would allow the device to connect. So how do you know that you're connected to your car, and not to the black hat AP ne

My point here more than anything else is that I find this formulation unsatisfying because it is "easy" to verify that we have a witness, but is exponential only because the size of the witness is exponential in size. What I'

I disagree with the formulation of "decision problem" here. The problem, properly phrased as a decision problem, is "For a given K, does there exist a string with K 1s". While it is straightforward to answer in the affir

by andrewla 2y ago
Straightforward to pose as a decision problem -- you're given a sequence of {0,1} representing a base-2 input (N), output a string of {0, 1} such that there are N 1's. You could make it "N 1s followed by N 0s" to avoid b

Hmm.. I'd love to see a more formal statement of this, because it feels unintuitive. Notably the question "given a number as input, output as many 1's as that number" is exponential in the input size. Is this problem the

The crazy thing about the definition of NP-completeness is that Cook's theorem says that all problems in NP can be reduced in polynomial time to an NP-complete problem. So if a witness to a problem can be verified in polynomial time, i

Linear in the size of the witness, however many bits it takes to express it.

The goal here was to show that it was strictly NP-hard, i.e. harder than any problem in NP.

I mean, have you ever had to deal with regulators? Departing from industry norms will 100% be used against you in any regulatory proceeding, no matter how minor. It is naive to think otherwise. Regulators go after big pockets and The guidel

?? This does not clarify -- your initial post made a claim about 0^2, which (correctly) does not appear in this list. Moreover it is trivial that there are no negative powers of 2 that have all even digits, since the trailing digit will alw

I mean, clearly it isn't in this case. But given that the digits of 2^n are cyclical at each decimal position, it does feel like this should fall out of some sort of chinese remainder theorem manipulation.
