nah, anyone can buy Ripple and have a Ripple wallet. Only thing you can't do is mine Ripple.
Yes.

Stocks represent ownership of an actual company that produces things and sells them, creating value. The price of the stock reflects an estimate of the future profits, the true value. If you buy all AAPL shares, Apple's future profits are yours. If some people (for whatever reason) sell AAPL while the estimate of future profits is not affected, price will drops somewhat and then value investors will swoop in to pick up the cheap shares. Others might disagree with the assessment, but future profits would vindicate the value investors. In other words, true value is realised and revealed over time. Thus, you have feedback loops that should keep the share price somewhat anchored to true value.

However, with Dogecoin, there is no intrinsic value, but solely what people assign to it. If people sell Dogecoin, that is ipso facto evidence that it's worth less, which can set of vicious cycles, run-away feedback loops, both up (bubbles) or down (crash). There is no true value. It's different from stocks.
Just like Filecoin and Ethereum this is a possibility to use cryptocurrencies for something smart and distributed instead of just as a settlement layer between banks.

If mining is somehow built on shuffling messages around this might be the good parts about old Skype (close to decentralized) without the problems (steals your bandwidth without asking).

That said: as with anything cryptocurrency-related I'm hugely sceptical.
Surely they use asymmetric crypto, so the private key needed to sign code isn't present on the console at all?

Spectre might make it possible to dump the public keys but they're not very useful to us.

Dentacoin cryptocurrency value continues to surge
> The current amount of bitcoin in existance is increasing at a rate of 12.5 every 10 minutes

An increasing monetary base and deflation are not mutually exclusive. They tend to go hand in hand, but not always. Bitcoin's monetary base is increasing, i.e. there are more units today than there were yesterday. It is also deflating, i.e. one Bitcoin today is worth more than one Bitcoin yesterday. (More precisely, one unit of real goods or services are worth fewer Bitcoins today than they were yesterday.)

I've a question for you since you seem so knowledgeable on the subject.

From my understanding the Airbus A330 and - A340 are pretty much the same plane, with the exception that the 340 has 4 engines and the 330 2.

Assuming that the desing is pretty much the same (inlcuding capacity of the fuel tanks) why is the range of the 340 much farther then the one of the 330. This seems somehat counter intuitive so I was wondering.

Alas, I'm pretty sure that I'm somehow guilty of wrong think here. I just wonder why.

‘It Can’t Be True’ – Inside the Semiconductor Industry’s Meltdown
>What it has done is cause a collapse of the Bitcoin economy, i.e. the markets for real goods and services denominated in Bitcoin.

Bitcoin has been extremely volatile it's entire existence, and yet many merchants adopted it as a payment method.

I'll say it again, it's not "deflation" that's causing the collapse of bitcoin (although I'd argue it's not collapsing right now, but just struggling), it's the fact that a blockchain cannot scale at this time.

Steam used bitcoin for years successfully, and only recently had to stop because of transaction fees. Microsoft used bitcoin for years happily, and only recently had to stop because of transaction fees. All of these companies that are no longer using bitcoin, cite transaction fees as the reason, not the "eventually deflationary" nature of it (which was always the case, even when they started using it).

The blockchain as an idea cannot handle this kind of scale, and until that problem is solved, all decentralized cryptocurrencies will fail to get past this hard wall, whether deflationary or inflationary. Luckily there are many bright people working on this problem, both in bitcoin and in other altcoins, and I have hope that it will soon be solved, but until then cryptocurrencies will struggle to reach mass adoption.

Self-concious Statistical Methods: Difference in Performance as a Feature
Recently someone asked in a blog how to incorporate zip code to machine learning algorithms. Thinking about this problem, I suggested the following algorithm: Apply your machine learning method to your data without using the zip code variable, then for each zip code compute the associate model using only the data with that concrete zip code. Now, for each zip code compute the difference in performance between those two models, that difference in performance becomes our new variable, so one would expect the machine learning algorithm to use this new variable to improve the prediction, and at each step we can use as a new variable the difference in performance betweeen the model with the old information and the new information provide by the difference in performance. I would expect a good algorithm to converge to a fixed point in which the new variable doesn't change form one iteraction to the next. If the algorithm converges to a fixed point then one could call the algorithm auto-correcting or autoconscience because is using the new information to take conscience of itself (how it performs on input).

Perhaps such kind of algorithm is long time known, but it seems a promising algorithm when coupled with an adequate model. It seems that the book of Andrew Gelman about hierarchical models can contain information about such questions. Can some expert on statistical models chime in and give some references about this algorithm?

Edit: Such kind of algorithm is trying to supervise itself to improve. The fixed point obtained is a way to encode the information provided by the new variable to the selected model, so that fixed point is model dependent. If the new variable doesn't provide new information then the difference in performance should be statistically zero, and so the new variable is constant equal 0, and this becomes the fixed point. So any algorithm able to compute averages shoud be able that the information of random variables is zero.

Not really. The 737 is sorta like the Porsche 911. Same name, same shape, almost a totally different plane under the skin. When the 737NG came out in the mid-90s (-600,-700,-800,-900) is was basically a brand new airplane.

Now, 20 years, later, Boeing has just started deliveries of the new 737 MAX generation, which again brings substantial improvements.
A huge chunk of that was that he was fed up with stable distributions shipping older versions of his software, so he'd get inundated by bug reports from users who were reporting things he'd already fixed. He argued that distros like Debian Stable and RHEL were actually more prone to bugs because of this. He wanted distros to use either rolling release or the Microsoft/Apple model, where the OS vendor only ships the base OS and all other software is acquired from third parties.

Because of this, he ended up putting in a termination clause in his license:

Not trying to be rude at all but that's a bit of a dream world. In all of human history the very second someone invents a lock, someone else starts figuring out how to break it. This is extremely unlikely to change, mostly because it's fun and rewarding.

I'd agree the biggest issue in Computer Security is culture but it's not that too many people learn what security is, it's the complete and utter disregard that the majority of developers show for the basics. Combine that with a general attitude of Security experts looking down at non-experts (I think this is getting MUCH better thankfully) and it's no wonder most systems are like Swiss cheese and full of wholes.

>people in the U.S. are far more free, prosperous, and safe than those in China.

This sort of statement is entirely subjective. As a counterpoint, many people in China would say the US is less free and less safe, because the US has by far the most amount of people locked in cages and a higher per capita homicide rate.

Whether or not one country is "better" than the other is nationalist subjectivity.

> Say he owns them all and then starts an auction for one share every day. Could you still take the price of that one share per day to determine a total value of the company?

Minority discount models [1] are notoriously useless or hairy, owing to the complexity of the body of law governing what a controlling shareholder can and cannot do to minority shareholders (and how likely they are to get away with it). The inverse of those models is the control premium [2], the amount an acquirer is typically wiling to pay over the public stock price to buy every last share.

We could quibble about whether the $900 billion company is worth $1 trillion or $800 billion after being taken over (with or without stubs [3]). What we will probably agree on is it is worth more than zero. That's all that is germane to my original argument.

1) Ryzen is absolutely vulnerable to Spectre, however desperately you don't want to think so. (I don't want it either; I just bought a Threadripper 1950X, after all)

2) If you actually think the eBPF JIT being turned off is going to save you and that Ryzen is magically immune because it's off: you're deluding yourself completely. Thinking eBPF is the key or whatever is a full misread of the actual vulnerability... Attacks never get worse, they only get better. You are guaranteed to see more exploits that do not leverage eBPF, but other components of the kernel to compose gadgets. Modern systems are millions of LOC; there's ample surface area for this to happen.

I'm more giddy to respond to questions like this than I should be, given that information criteria are an area of my research.

AIC and BIC are approximations to other quantities under certain common but idealized scenarios. What's become clear over the last 20 years or so is that for most other scenarios those approximations are not nearly as good as other approximations, or just calculating the targeted values of interest.

So, for something like DL models, criteria such as AIC and BIC are less applicable. But what is confusing to me is why other information criteria aren't pursued more. There's literature on the asymptotic equivalence of cross-validation and certain information criteria, and CV has certain problems that those criteria overcome (I've been looking citations but Google thinks I'm spamming it or something).

I think part of the reason for the adoption of CV is a cultural one, to be honest, and due to historical quirks. Like bootstrapping and other empirical simulation methods, it has an appeal due to its relatively nonparametric nature. But there is a ton of mischaracterizations about CV (e.g., relative to bootstrapping) and its warts have been overlooked in general due to the position it has attained in applied settings.

There is also a huge gap between the literature on information criteria and the rest of statistics and applied data analysis. People tend to learn about AIC and BIC through certain standard sources, sources mostly pertaining to their initial derivation, or that follow the same line of reasoning. But there's other literature that derives AIC and BIC through other means, or approach them from other perspectives, and that literature tends to get ignored. As a result there's a lot of misleading statements that are made about each, even from talented individuals (e.g., that the rationale for BIC depends on Bayesianism, or that there is a true model under consideration), and a lot of advances in the area are totally ignored. It's like there's two literatures, one attended to by people who are interested in information criteria, and another by people that "just want to understand AIC and BIC." It's confusing to me really, because I generally see some kind of trickle-down in other areas of statistics, but with information criteria, it's like there's an enormous gap.

> it's not "deflation" that's causing the collapse of bitcoin (although I'd argue it's not collapsing right now, but just struggling), it's the fact that a blockchain cannot scale at this time

I agree. I'm only refuting the argument that Bitcoin is not deflationary.
That’s odd, I live in the Bay Area and all of the grocery stores in my town (big chains - safeway and lucky) carry Macs. I know this because they are my favorite, and the ONLY apple to use for cobbler, crisp, or pie.
>It is also deflating, i.e. one Bitcoin today is worth more than one Bitcoin yesterday.

But that's explicitly false, especially today (what with bitcoin being down 14% over the last 24 hours). And there was a period of bitcoin's history of about 3 years where the value of one bitcoin was dropping day after day. Does that mean bitcoin was inflationary during that time?

I just can't see that as being a useful definition.
For example, you have Norwegian Airlines recently offering direct nonstop service from Oslo Norway to Orlando, Florida on the 787.

I'd consider Norwegian a bad example since they position themselves as an ultra low cost carrier. The economics there are somewhat different in that they don't usually offer connecting flights via one of their hubs. Ryanair just recently and very tentatively even began offering connecting flights, but it's not necessarily their business model, which is no frills direct connections.

As for major European hubs. Note that they are not necessarilly used by ULC carriers.

I don't know if this is still the case, but when you took Ryanair to Barcelona you wound up in Girona and Stockholm wasn't really Stockholm. Second (or third or fourth) tier airports sometimes offer very attractive conditions to airlines just to get passengers, which make the attractive to ULC carriers.
From what I can tell the hard-coded backdoor vulnerability was remediated, but I see no indication the unrestricted file upload vulnerability has been remediated in any of the firmwares I tested. But I'm not a security expert. I've reached out to Gulftech and WD for clarification.
I work on a system where arbitrary property access results in database round-trips.
So the following code:

foreach(var b in a.Bs)
{
if(b.Data != null)
{
ThisIsInteresting(b);
}
}

results in a.Bs.Count + 1 round-trips to the server and then database if these fields have not been accessed before. (a.Bs is one and b.Data != null is one as well).

This is a fine example of what I'd call "unreadable" code because there is so much activity that is implied by actions that in other systems are completely innocent and well isolated.

Also there is the point of cognitive load. If your entire application was simply one function it is technically "readable" but the cognitive load of trying to work out what is in scope and what might change a given variable is too high to read without extraordinary effort.
When working in such systems (as I have before) you HAVE to rewrite it to even start reading it because a human memory cannot hold all that information at one time.

I think brushing it all of this off as "the reader isn't reading well enough" is disingenuous.

That is a strange and "unnatural" (for me) use of the word "complicated". Cynefin[1] defines 'complicated' as "known unknows" and 'complex' as 'unknown unknowns'. The idea is that complicated things are non-obvious, but they are understandable (with expertise, you get the relationship between cause and effect). With complex, full cause & effect cannot be known apriori, it's just observable after the fact.

That somewhat resonates with the definition that complex (code) is about intertwining - 'complex' is problematic because as things get more and more complex, you can have only a local understanding, and can't possibly hope to grasp all the implications of a code change. This suggests that "complicated" is something that is "somewhat complex, but still manageable with sufficient expertise/domain knowledge". I tend to use "complicated" to denote something that has inherent complexities (due to the nature of the real world); and "complex" to denote something that is artificially complex, due to ... well, lack of thought into making it as simple as it could be. In that sense, I view "complex" as being definitely worse than "complicated"

Have you upgraded the firmware via Ubuntu Capsule upgrade?
But by that definition bitcoin is inflationary depending on where you draw the lines. There was a period of about 3 years where bitcoin's value was dropping every day, and just this weekend it dropped 10-20%.

How can "deflation" be a useful definition if it can apply or not depending on the ever changing value of an asset? or even what you compare the value against.
That people spend less when they have deflationary expectation is not only a fancy theory, but a fancy theory combined with empirical fact. Read about Japan's lost decade. (Of course it's not going to be a problem with crypto anytime soon, because nobody measures their wealth in crypto, because nothing is denominated in crypto.)

The other problem with deflation is that it increases the real value of debt, making it harder for companies/borrowers to repay their debt.

Thus, it also tends to increase inequality (rewarding savers, punishing borrowers).
