> x^0 is intuitive

So you say. If it's planly obvious, why do I get so many results for the Google search "why is x^0 1"?

I understand the multiplicative identity argument, but that's a technical explanation, not an intuitive one.

What's the intuitive reason that multiplying something zero times should equal one? If I don't multiply, then I don't have an answer, and zero's closer to nothing than one is. Why should I use the multiplicative identity if I don't multiply, why would that make sense?

Using the multiplicative identity is yet another choice, not an intrinsic property of numbers. It's a very good choice, and there are a lot of reasons why it's a good choice.

https://en.m.wikipedia.org/wiki/Empty_product

"In mathematics, an empty product, or nullary product, is the result of multiplying no factors. It is by convention equal to the multiplicative identity 1 (assuming there is an identity for the multiplication operation in question), just as the empty sum—the result of adding no numbers—is by convention zero, or the additive identity.[1][2][3]"

> x^0 isn't defined to be 1, x^0 IS 1.

Are you sure? How can you show that? How do you define what an exponent is without defining what x^0 and x^1 are? What does it mean to suggest that x^0 is intrinsically 1? Are you absolutely certain that you just aren't so comfortable with the idea that you can't imagine other possibilities?

https://en.m.wikipedia.org/wiki/Exponentiation

"Formally, powers with positive integer exponents may be defined by the initial condition

b^1 = b

and the recurrence relation

b^(n+1) = b^n * b"

Yes, let's just completely dismiss the concerns of people whose preferred way to move up and down in a web page is to grab the slider with their mouse or stylus. Everyone is perfectly able to curl their fingers around a little pod that makes them put their wrist into a position that can cause strain on the tendons and make lost of tiny, precise movements with it. Nobody has any RSI issues.

Well, there were people voting to leave and using "immigration" as their justification. I would never claim it was 52%, or that 52% of the UK are 'racists'.

However, it was a factor for some portion, and it may have been enough of a portion of votes to be part of the few % that gave 'leave' the victory.
I worked in the lab at the Nation Physical Lab in the UK that had the low pressure + low temperature STM, we used to make the tips by dipping the ends in a very strong solution of NaOH. You relied on the surface tension as it dissolved to produce you a very sharp tip.

Surprisingly easy.
I do accept it completely. But how can It suggest some other person data for someone else. I might have wondered if they got somehow my number, but i will be shocked if it suggests some other number for me
>That's the calculation the British public made.

Have you seen any of the interviews with the British public who voted leave? Not many were doing that sort of calculating.

If such a popular GC-using dependency came into existence, then there would surely be demand for a drop-in replacement that didn't use GC.

Remember, even the proposed Gc<T> type provides very little in the way of ergonomics (at least compared to garbage-collected types in pervasively-GC'd languages). Essentially it would just be a souped-up Rc<T> with no need for weak pointers to resolve cycles. Alternatively, it would only be used to interoperate with a foreign codebase that already uses GC, like SpiderMonkey or V8.

Given that people tend to only be writing Rust in the first place if they put a large degree of value on performant solutions, I'm not too worried about the library ecosystem suddenly sneaking in GC everywhere, especially since the Rc type is already halfway to garbage collection, and I don't see it used unduly in the wild.
> would love to know how someone would do a study on the subject

It's normally called the "Shy Tory Factor" in the UK; Wikipedia has a page [1] but it's a bit thin.

After the 2015 GE the British Polling Council commissioned an independent inquiry on the subject, whose findings you can read here [2]. (Disclaimer: I haven't.)

What strikes me is how counterproductive this all is - in this week's case the inaccurate polling made the final result far more of a shock and thus presumably far more disruptive than it would otherwise have been. It may even have caused the final result - I think turnout for the under-25 demographic, which skewed heavily Remain, was only about a third, and I've seen several comments to the effect of "I didn't think I needed to vote, Remain was ahead anyway".
The BBC purposefully tries to be impartial, the "picking the winner" part was based on polling data and the actions of the financial markets. Other media organisations did the same.

As there was no exit poll, they had nothing to talk about for 2 hours before the start of the results came in so just had endless speculation from pollsters and their ilk

If there is one lesson to be learned, it's never ever trust polling organisations, they get it wrong time and time again, but somehow keep getting paid?
Really? I thought it was a lot more expensive than that when I was there.
Another aspect of social engineering that is seldom discussed: Women will have a higher success rate at any sort of information-extraction, in fact, I would say that it is a "social engineer" method in itself. The crying baby sound-effect? Simply icing on the cake.

If a male with a naturally brooding voice contacted a service provider to extract a password, his chances of success are lower because he is less trustworthy by nature, which increases the odds of the operator on the other end raising suspicion.
"And the reason Mirantis has been successful is because, despite ourselves, outcomes are what we’ve been able to deliver to our customers by complementing crappy OpenStack software with hordes of talented infrastructure hackers that made up for the gaps.

That's quite an interesting take, but I've imbibed too many Alan Kay talks to buy it except as a case study in bloat.

I think they're banking on user behavior being as follows:

If the correct number is suggested, you get slightly creeped out, but confirm. If the wrong number is suggested, you get slightly outraged or puzzled, fill in the right number, and confirm.

It's sort of a natural A/B test: will people respond better to the correct number, or the wrong number? And they don't even have to control the A/B population, it's just whatever their reverse lookup API returns.

I keep hearing this on the internet being portrayed as if the "average person" thinks "taxes are too high". The truth is this[0], it isn't just that they are too high for some groups, it's actually a plurality who feel taxes are too low on some groups and institutions.

This seems to be a growing sentiment, perhaps in response to the enormity of modern smartphones. They're no longer a convenience but a payload.

Check out the variety of standalone smart watches coming out of China now, some even run full Android 5. I'm thinking of one which could act as a 3G-to-wifi hotspot for a tablet for when I do need to work on the go. That also gives much more flexibility in selecting a tablet without a SIM.
Because you're making this comment in the context of a story about actual lynching and mob violence.
Not only that, but there are other even more obvious properties of the set of integers that don't inhere to other sets of objects since discovered. So your claim is essentially that there are no obvious properties of integers, which leaves one feeling a little flat.

> isn't it just mutability with different syntax then?

For one thing, in order to take a mutable reference to a binding, that binding must be declared as `mut`.

let mut a = 2;
let b = 3;
let x = &mut a;
// let y = &mut b; // error: cannot borrow immutable local variable `b` as mutable
Could you post a quick summary describing the technique? Sounds like my definition of esoteric fun, haha.
Thank you for marking this as a dupe! Makes things better! :-) I should have searched by title, not URL!
As far as I know, using a composite modulus is bad. It means that some of the integers (besides the obvious case of 0) no longer exhibit the group properties. That said, it only makes it a bit more difficult to find a generator. I am not sure about the overall security implications.

However, the plan here is too get someone to use your chosen modulus which is weaker. I'd suppose they are banking on no one checking that the modulus actually is prime.

I'm still amazed at how such a blatant forgery was not called out more strongly, given the obvious flaws, not the least of which was its provenance from the same mystery source as another known fake.
> But the brain doesn't run out of storage space

I felt that way when I was younger but eventually lost my taste for poring over masses of "just-because" detail, and became more sensitive to the cognitive cost of doing so. It isn't merely that the time and energy could be spent on other things, but that the brain responds to learning by patterning on it. If I spend energy on that, my work gets more like that and my brain thinks more like that, and I don't want them to.

(By the way, I'm not criticizing those books at all. I don't know them, but if they're as good as you say I think that's great.)

I mean the UK. The UK is a commonwealth country and a fiveeyes country. It makes no sense for the UK to be in the EU.

The fact that Ireland has high EU approval ratings is immaterial to the fact that it's not logical to have it be apart from the UK. This is a tragic artifact of history. Ideally this would be fixed, but I agree it isn't likely to happen.

You wouldn't need a counterbalance if things were done right, which is to have the larger chunks (today's England, Scotland, Republic of Ireland) be split into more similar-sized chunks. Having a couple dozen chunks (called what you like: parish, county, state, province...) is probably sane.

That's a very negative opinion of human nature, and a big reason I thought Wall-E was bullshit.

Humans enjoy their bodies. We play sports because it's fun and feels good. We enjoy the burn of a good run. We like to look in the mirror and see something vaguely attractive. We like to fuck. And we want to fuck people we find attractive.

Wall-E got it totally wrong.
We (at Stack Overflow) have a new documentation product coming down the pipe with an emphasis on examples and I thought it would be awesome if we could expand our stack snippets feature to languages beyond javascript. A reproducible example right there on the webpage. In researching existing solutions, nothing was satisfying, and then I had the idea to just use asm.js and write an MSIL interpreter. I spoke with some people familiar with asm.js and decided that it wasn't particularly difficult, but it had a ton of limitations from js file sizes to ways to get all of the libraries people ask about uploaded, and of course regular breaking changes in the browser. Wasm seemed like it could help with some of the issues being a formal web specification with representatives from multiple browsers.

Other than that, I can see a lot of uses for it, from small neural nets in the browser to high performance applications like photo editing, and of course gaming. It might not be for all applications, but it certainly has a spot.
I think the BBC does a reasonable job of remaining neutral between political parties - as you say, the complaints more or less balance out. But as an institution they very definitely have a strong ideology (pro-EU, pro-multiculturalism) which doesn't accurately reflect the country as a whole. Part of that is just the London filter bubble, but not all of it.

A recent memo by the BBC's head of political research admitted this:

“It seems to me that the London bubble has to burst if there is to be any prospect of addressing the issues that have brought us to our current situation. There are many millions of people in the UK who do not enthuse about diversity and do not embrace metropolitan values yet do not consider themselves lesser human beings for all that. Until their values and opinions are acknowledged and respected, rather than ignored and despised, our present discord will persist. Because these discontents run very wide and very deep and the metropolitan political class, confronted by them, seems completely bewildered and at a loss about how to respond (“who are these ghastly people and where do they come from?” doesn’t really hack it). The 2016 EU referendum has witnessed the cashing in of some very bitter bankable grudges but I believe that, throughout this 2016 campaign, Europe has been the shadow not the substance.”
This was in 1984, and it was for experimental chips, not production chips. The layout was done using CAD tools, but the placement was all manual.

Also, I think they were analog chips, not digital. I'm not sure. This was a co-op job in my first year at college at the IBM plant on Cottle Road, and I was never fully in touch with the big picture. I think they were making big-ass hard drives, and the chips I was working on were part of the circuitry that amplified the raw signal from the read-write head, but those details were way above my pay grade.
"...which of course lead to our engineering fees looking like a larger portion of the job."

So there you go. Mismeasurement is 99% of all business problems. I've been laid off before because I didn't generate the (apparently) required level of software defects and missed a gate or two by a day or two doing it. I was actually told I didn't look busy enough.
Are there any languages that use a different syntax for shadowing assignment? As in:

Scope 1

let x = 1
let x = 2
=> error, rebinding variable in scope not allowed

Scope 2

let x = 1
shadow x = 2
=> works!

Scope 3

shadow x = 2
=> error: no variable x to shadow declared in scope

I wonder how well something like that would work in practice.
It's posted on the Ron Paul Liberty Report, so it comes from a very...specific point of view. They don't shy away from trying to frame vast, complicated events and issues in terms of relatively simple, reductionist narratives full of good and evil, heroes and villains, etc. See also: Greenpeace, PETA, the FSF, and many religions. :( They think it makes them sound more credible rather than less credible, and the sad truth is that this approach works because it plays right into common cognitive biases. I don't think it's dishonest- I think these types of thinkers believe what they're saying, it's just unfortunate.

Sure, that's probably true. They don't need to listen to him, though; elites do. Then elites, through various mechanisms, need to a) communicate effectively to do those who are now disaffected and more importantly b) create conditions where bigotry (and other forms of exclusion) do not overtake good sense because of economic pressures / scarcity / perceived scarcity.

It certainly won't be overnight, but the sooner they start, the sooner we can start fixing things.
I don't think the US news media works that way. I think that the news media makes every person feel that they are the sensible person of non-extreme nature, and that to the sensible person their views are so obvious, and that other outside people are hostile and ignorant.

I don't think anyone would tolerate even 5 whole minutes (!) of mockery from their favorite news distributors. I also think most people aren't looking for news, but opinions. They want already-respectable sounding narratives that they can adopt themselves without spending any effort.

So no, I don't think religious people of America watch in pain as their news distributors, represented by a few faces, mock them for their stupidity, but I do think that news distributors sell a very poor-hostile message to poor people as part of an aspirational twist.

You aren't the lowest, you're actually kind of normal, but elites have been stepping all over you. But the people below you, those are the losers, and those people don't deserve help because they're lazy, they're drug users, they're impulsive, they're unprincipled and selfish, they're Godless, and if the government gave them any help they'd spend it all on drugs and having 6 babies.

You can just picture that dirty-faced skank with ultra-short denims and a tank top, an utterly unkempt look of unabashed poverty, with her no-good boyfriend. She probably votes Democrat all the time because if the government gave her a handout, hey of course she's going to vote for them, the Democrats are basically buying drugs for her.

Good on Snowden for calling Putin out, but I don't think it'll mean anything. It is reassuring to see a reminder that his warm welcome in Moscow was just a diplomatic на хуй/fuck-you to the US. Reading some comments about Snowden made me think I had unwittingly Rip Van Winkled my way into some weird future where Russia was a bastion of individual liberty and respect for human rights.
I would be fine with them not doing that. I canceled my Oculus pre-order and ordered a Vive instead when they started doing that, even though it meant an inability to play the locked-down games. I have 0 interest in having a part of my game library being locked into a DRM'd hardware ecosystem, where my games stop working if I want to buy a different brand of second gen hardware.

Also, in return, they get more hardware sales and a more vibrant VR ecosystem, so they don't get nothing. One alternative is to set up a joint VR development fund with Valve. It sounds like Valve is doing this on their own, without exclusivity requirements.

One important note is that this holds for general grammars that can contain everything. If the grammar is restricted somehow, for example to lr(k) then the best complexity is linear (there are even parsers that manage both LR(n) in linear time and general parsing in cubic).
