Amazon’s algorithms are designed to spot unusually high prices – that is, high in comparison to other sellers on Amazon—and suspend those accounts. The expensive water is showing up because sellers with cheaper water have sold out and more expensive items previously buried in search results suddenly rise to the top.

I'm not sure what I would tell people who are upset about price-gouging. Should Amazon go out and buy water and sell it's own at a loss? It also seems weird to be ordering water from Amazon and hoping it beats the storm.

I remember in economics learning that certain people would rather the product not be on sale than to see it listed at an "unfair" price. Which seems to be the case here.
Working in scientific software development, I've seen quite a few people developing on Macs who would really appreciate OpenMP support. They end up having to use GCC or a vanilla Clang, but it's extra work and it comes with its own caveats.
Humans are always lossy filters, more lossy in some areas than others. There is also no 'bowing' required, and there is no correctness.

The recruiter wanted to put pegs in holes (which is essentially what selection is), but mistook the request for a red rond peg for 'only a specific type of red' peg. The peg in this situation might have been fire engine red, while the recruiter had poppy red in mind. In both cases, what they both should have in mind is not the color of the peg, but the shape. Swap peg with 'POSIX' and color with Unix, Linux, Unix-alike and you're back in context.

In this specific context, the one setting up the list of requirements should have specified "any posix, unix, linux or similar knowledge" as one single item, and then the recruiter should have matched any response that contains either posix, unix, linux or bsd, or a combination of those. This same problem could have happened if someone wanted a lathe operator that does threads, but the respondent lists NPT, TPI and M, but the recruiter doesn't know the area of expertise to filter for that and thus loses the input completely.

Aside from that, there is emotion and intonation and tone and appearances, but that doesn't have anything to do with the concept of 'lossy filters' and it totally irrelevant regarding that.

Ketamine, I do believe, is an animal tranquilizer. Not being a veterinarian, I don't know much about that application. However, in humans it has shown tremendous benefit as an analgesic and a dissociative agent, with a tremendous safety profile.

The problem with reducing a movie to a single score

Actually, they use two numbers, which is interesting. The most prominent one is the "TOMATOMETER", which measures the % of critics who said it's worth watching. Below that it shows the average rating.

> "The cure is ketamine? That's an animal tranquilizer."

https://en.wikipedia.org/wiki/Ketamine

Ketamine has very important human use. From article above:

"It is on the World Health Organization's List of Essential Medicines"
Yeah, there are better ways to represent scoring, such as Amazon's histogram of star ratings. Unfortunately, that doesn't help Rotten Tomatoes, because they often don't even have a graduated scale to measure in the source data for critics. When many critics are just recommending or not, their scale is basically 0 or 1. They are extrapolating out of much lossier source data.

This is also why I dislike Netflix's rating system. There's two axis by which it's measuring (how good the movie is, and how well it matches your interests), and turning a 4 level rating that already combined those nuances into an 8 level aggregate rating and then altering that score based on similar interests lead to quite a bit of confusion as to why something was rated the way it was. Then they doubled down and made it worse by reducing the source data rating to 2 levels and increasing the aggregated output to 100 levels. :/ The only upside is that they are able to throw some interesting compute power and algorithms and/or machine learning at it to generate some good suggestions occasionally.
What Alice is the victim of is slander, not fraud or identity theft. The bank lent some money to someone who claimed to be Alice (though the bank only relied on the fact that that person knew Alice's SSN as proof of that fact). Then when the bank didn't get paid back, they told a bunch of credit check bureaus that Alice was a credit risk. This was a lie about Alice, which has a material impact on Alice's reputation. The credit agencies then go ahead and repeat that slander.
This paper is a reasonable attempt to model bitcoin by people who only see the surface of what bitcoin is.

Bitcoin is like an Onion- it has layers, and makes you cry.

As I have come to understand it there are many layers- both in technology and economics- at work here.

Most obvious is layer 2 tech like lightening network, side chains, and segwit. (which is a second layer inside the blockchain.)

But as you come to understand it better you realize, for instance, that the network has been under attack and the cost of fees is mainly due to that (when its not under attack because the attackers are moving their bitcoins) you can do micropayments-- like $1.50 sent for $0.05 transaction fee with 3 hours clearing-- which is faster and cheaper than credit cards. You get censorship resistance for free!
I agree, the pun has a negative connotation whereas the article is about a feat.
The example you cite, however, is an argument for Rotten Tomatoes system; as the FiveThirtyEight article notes, the movie has a "great" 78% among critics. This is due to the RT score being a weight of reviews which have been flattened to thumbsup-thumbsdown.

Fraud isn't limited to credit. My dad had someone open a savings account in his name and transfer a significant amount of money via ACH. He only found out because he got a welcome or from the bank!

The police investigator told him that the particular fraud that he was a victim to was impacting >500 people and >$5M
>Satoshi decided to decrease the amount of rewards as the network grew older and presumably more users would adopt it, why?

Mining needed to have a way to incentivize miners before transaction fees were common, and there needed to be a system to get bitcoins out into users' hands to begin with. Once a critical mass of users have bitcoins and transaction fees support mining, there's less reason to continue minting new bitcoins.

It could be argued that continuous minting creating inflation would be desirable, but that's a big free parameter that there isn't a known best way to calculate. Bitcoin's monetary supply code was intended to function long-term, and if minting was to continue indefinitely, it's debatable what the minting rate should be, and if it was gotten wrong, it would be extremely controversial to ever change. (Some people might think 2% is a good inflation rate, but what if that's specific to now? Say economic and population growth slow down; 2% could be too much inflation.) Having the cap approach a maximum limit instead of increasing forever seems to have been a much easier decision to make and get others to trust. If there's a fixed amount of Bitcoin, then as long as Bitcoin's usage isn't decreasing, it's straightforward to imagine that the value of Bitcoin shouldn't approach zero.

>And the supplies of this type of service are increasing with every day as alternative networks offering the same service (blockchains, trustless distributed databases) are increasingly sprouting up.

A big part of Bitcoin's value is the network effects of its current user-base. The creation of an altcoin doesn't immediately fully dilute the supply of useful bitcoin-like cryptocurrency if it doesn't have the userbase.

>If I have a gun and say, "don't take my water or I shoot you" I have prevented you from acting thus not coercion.

This is an alteration of the definition given. Up above, you can see that this exact situation falls under "threat of physical force in as a mean to get someone to comply with your wishes"

>Markets are not coercive because you are not threatened with force if you don't participate. Taxes are coercive because if you don't pay, the government comes and takes your stuff or puts you in prison.

But you are! Markets rely on property and contract law. Let me lay out the example. You are selling water for $100. I choose not to participate in the market and instead steal a case of water and take it home. Later the government comes and takes my stuff and puts me in prison.

So here we see that by the same token tax law is coercive, so are property and contract law. If property and contract law are coercive I don't see how you could ever say that markets aren't since they are the foundation of a market system.

To be fair, CNTK (BrainScript) has quite impressive list of features to support dynamic control structure (in a symbolic fashion, comparing to PyTorch which delegated much of the dynamic control structure to underlying language Python). I think Tensorflow and CNTK probably the only two frameworks pursued such implementation strategy. IMHO, looking back, supporting control structures may not be that useful (see the recent attention based models, all of them can be unroll'ed to ordinary graphs), but it is so interesting to implement!

Pretty normal. Their lawyers likely said that as long as they reported in (via Form 3 and Form 4) then it would be complaint enough.

So this was still transparency, and its just fodder for reporters to debate about, because without the Form 3 and Form 4 regulation, you would never know.

The credit agencies report what has been told to them by BigBank. Once the fraud is detected BigBank should update them that Alice does not in fact have a $10,000 loan with them and it would then be removed from Alice's report. If the loan has been determined to be fraudulent and it has not removed from her credit report, BigBank is victimizing her not the credit agencies.

This is why Metacritic could be considered more accurate. While Rotten Tomatoes takes each movie review as binary--bad or good, Metacritic puts a number estimate on each review between 1 and 100--bad to good--and then averages those in.

If you're able to write a robust shared ring buffer in C, you should be able to do the exact same implementation in unsafe Rust using raw pointers, declare it as Sync and use it from safe Rust with no issue. Or am I missing something ?

Oh wow. Will that be investigated? This isn't a world I know much about, but surely that's gonna be a problem?
The problem is that you need a replacement, something that can actually be used as a solid proof of identity.

The countries that don't have comparable identity theft problems have done so mostly by using an ubiquitous government issued ID that's hard to forge and hard to obtain by someone claiming to be you. In USA there seems to be a strong opposition and a legal barrier for the government to make such an ID.

Not much else can be done - a simple test of a decent identity system is to ask if my spouse, mother or brother would be able to impersonate me - it's clear that nothing that relies on "something you know" can ever be sufficient, it must be "something you are", possibly together with "something you have", i.e., biometrics or a trusted photo ID.
Here is some more information about what LN is doing: http://dev.lightning.community/overview/
It's pretty much the flaw in not having a national ID scheme - everyone reaches for the next closest approximation, with no funding for security systems or refreshes to address flaws.

Because this is an issue the government should address seriously.
"Residents in the U.K. and Canada were also impacted." Yet Equifax is only providing lookup or TrustedID protection for Americans.

You're partly right. However, it's very common, even when people want to draw exactly the distinction you're talking about, that they'll just use "history" to refer to a period for which there are any records. That's a pretty different concept from the period for which there are records of the strength of hurricanes.

No, it's not; SSNs aren't passwords, and shouldn't need to be “secure” in that sense, but names aren't secret and birth dates and locations are easily discoverable (and the combination of all three is frequently publicly announced!), so this would be less secure.
This is why I've finally accepted the fact that for my own personal tracking, nothing beats a post-it note. I'm not going to spend the time to put down all the real information I should and dealing with an app is another barrier preventing me from getting stuff done.
Just an odd note, I agree with a lot of the comments on this thread, but I thought Drive was a fantastic movie.

I saw it in the cinema and remember my heart was rushing from all the emotion after seeing it. I could hear the soundtrack in my head for days afterwards (it may be the best part of the movie for me). Drive's easily in my top 10 of the last decade.

Maybe my taste is just strange.

"LLVM compiler recognizes opportunities to transform a branch into IR select instruction(s) - later it will be lowered into X86::CMOV instruction, assuming no other optimization eliminated the SelectInst.
However, it is not always profitable to emit X86::CMOV instruction. For example, branch is preferable over an X86::CMOV instruction when:

- Branch is well predicted

- Condition operand is expensive, compared to True-value and the False-value operands"

https://reviews.llvm.org/D34769

"We have seen periodically performance problems with cmov where one operand comes from memory. On modern x86 processors with strong branch predictors and speculative execution, this tends to be much better done with a branch than cmov. We routinely see cmov stalling while the load is completed rather than continuing, and if there are subsequent branches, they cannot be speculated in turn."
