> Are you saying you have evidence that the vast majority of people consider Bitcoin Cash and Bitcoin to be the same currency and I'm alone in considering these 2 blockchains 2 different currencies?

No, I didn't say that.

I'm saying that neither Bitcoin nor Bitcoin Cash are identical the original Bitcoin. Both have added changes, and this will be true of any blockchain that is being actively developed. In fact, to say that Bitcoin before the fork is the same coin as Bitcoin when Satoshi made it is also a bit off, because there were changes added before the fork, too.

I'm saying that saying that considering either one of these to be different from the original Bitcoin is a moot point, because any conceptualization of being the same coin doesn't really fit. The only way you could say that any variation of Bitcoin is the same coin is by saying that they build on the same blockchain, but both BTC and BCH fit that criteria.

You've focused in on the names people call the coins, which is pretty much the least important way one could say that coins are the same--implementation is far more relevant than name.

In the end, the only thing that really makes sense to say is that modern BTC and BCH are both variants of the original Bitcoin. It doesn't really make sense to say that either is the original Bitcoin, because both have introduced changes. It also doesn't make sense to say that either isn't the original Bitcoin, because they both originate on the same blockchain. The idea you're trying to apply here, that a fork means a new coin was created and the old coin continues on, just doesn't really capture the full truth of situation.

Looking at popular opinion as if that had any relation to reality is not going to help you understand what's going on here. Most people don't understand Bitcoin, so looking at the opinions of most people as if there's any truth there is pointless.
This is somewhat off-topic, but has anyone here used SessionStack?

How well does the service work, and is there a noticeable performance impact for the software to record on mid-range mobile devices?

It looks really interesting and would probably be really helpful, but I can't include anything else in our applications that will further tax our already struggling lower-end devices with more code that needs to run and more data that needs to be transmitted.

I‘m intrigued how a lag-less frame interpolation would work - the algorithm can’t look into the future, or can it?
The vividness of a memory is also misleading; people are always sure some memory is accurate because they can vividly recall every detail.

Except that the brain often will generate vivid details to replace or fill in gaps.

E.g. I had extremely vivid memories of a movie I hadn't seen for years, so I was surprised when I watched it again and I was very wrong in those vivid details. I had only retained the outline of things, some snapshots of things.

If you know a lot of people's personal experiences getting denied in modern day, I'd love to learn more! I don't personally know a lot of people of European or African ancestry trying in the first place, at least in modern day.

However, during WW II, there were many European Jewish refugees who became my family's neighbors in Shanghai, at a time when shipfuls of them were being turned away by the U.S. (Our neighbors were denied a visa to the U.S. at that time.) There was another previous wave during Russian pogroms.

Most people I've heard of getting green cards are of Chinese or mixed East Asian / Southeast Asian ancestry, and have an advanced STEM degree. I heard the scoring systems weighs Ph.D.'s and M.S.'s differently, and that computer science and EE gets you more points. I haven't heard of people getting assigned different weights depending on how Chinese their ancestry is. On the other hand, you'd probably have a hard time telling the difference between a Korean and a Chinese northerner who lives near the Korean border, as well as the difference between a Vietnamese person, and a Chinese southerner who lives near that border. We're all basically distant cousins.
"In 2015, AWS was responsible for two-thirds of total operating profit. Last year it was more than 100 percent."

AWS was responsible for more than 100% of the operating profit? Despite being impossible statistically, is this a sensationalist way of saying that it accounted for all of the profit and covered some or all deficit as well?
Yeah, I've not delved deeply into the details of his life but that would make sense. Have to imagine she was there providing that day to day support and helped give him purpose.

Each transaction spending the locked funds bears the signature of the party making the payment. The other party can then provide the counter-signature making the transaction valid on the Bitcoin network.

The main security problem to solve is preventing one party from publishing a previous channel state (half-signed transaction) giving themselves more money than they actually have by rights.

For example, Alice and Bob might start with a channel giving each of them 5 bitcoin. Then Alice makes two one-bitcoin payments to Bob:

A | B

------

4 | 6

3 | 7

Alice decides she wants to take back her last payment and instead publish the earlier transaction (signed by Bob) giving herself 4 bitcoin rather than the one giving herself 3.

This problem is solved with hashed timelock contracts (HTLCs). Without getting too technical, HTLCs make it possible for a party who spots a counterparty attempting to publish an invalid transaction to take all of the money in the channel (i.e., Bob would take all 10 bitcoin). The main idea is that cryptographic hash functions are one-way. If I make a payment contingent on knowing a preimage to a hash value, I can cause the payment to become valid by revealing the preimage.

Along with the signature to a transaction, Alice must also give Bob the preimage for the previous transaction before he will accept it. When she does, Bob knows that if Alice tries to play games, he can take all of her money.

This video gives a high-level overview:

Could you clarify you mean here? Something like this is perfectly valid:

fn no_mut(a: &mut usize) {
*a = 10;
let b: &usize = a;
println!("a: {}, b: {}", a, b);
}

fn main() {
let mut foo = 42usize;
no_mut(&mut foo);
}

If such pointer weakening was not possible, how would you be able to call a method that takes &self on binding of type &mut self? Of course, you can't use a mutably while b is in scope. So, something like the following results in a compiler error:

fn no_mut(a: &mut usize) {
let b: &usize = a;
*a = 10;
println!("a: {}, b: {}", a, b);
}
The answer is yes, if the processor supports PCID: https://news.ycombinator.com/item?id=16094349

Simplistically, it allows TLB-cached page table contents to be tagged with a
context identifier, and limits the lookups in the TLB to only match within
the currently allowed context. TLB cached entires with a different PCID will
be ignored.

If this is a serious concern for you, you can do an on-premises installation instead. In that case, none of your data ever leaves your intranet.
As with many online debates, this one seems to be based on a difference in definitions. Some people take "self-driving cars" to mean "cars without a steering wheel that will drive my drunk butt around in the rain", or even "no more human cars on the road". I still honestly think that this will never happen without radical changes to our roads, cities, laws, and economy. Others view "self-driving cars" as an extension of cruise control that might eventually become fully automated. This can be already be seen in cars by Tesla, etc.

I think the "5+ years before it's viable" crowd is mostly responding to drum-beaters of the former, not the latter.
No, I don't and I'm not sure what I said to make you imagine such a strawman.

I'm interested in whether you think YouTube should block Islam entirely, or perhaps to separate out the terrorist conspiracies within Islam from the rest and where to draw the line.

Would, e.g., this 12th Imam stuff, even from ostensibly peaceful folks who did not advocate violence, draw a ban in your view if it was also something terrorists used?

Please explain.
> It means that Bitcoin will just be a low-capacity settlement layer, and regular purchases will need to use PayPal-like middlemen to avoid hefty fees.

You're correct, of course. But what's wrong with that? You still retain ultimate sovereignty over your funds, which is the most important property, I think. What do you think is lost by Bitcoin being mostly a settlement layer with the option to transact on-chain for a higher fee?
Is there any proof that the technical work for IBM is sent out to Indian boiler rooms with very high turnover? Or is this just based on some belief that any software in India must automatically be shitty?
I've wanted to do this but with the Nest cameras I already have in my house. It's too bad that Nest has made the decision to completely discourage anyone using the video from these devices.
I'll share another bad experience. AstraZeneca pulled out of a $1.4 billion/7-year deal with IBM a couple of years early, because of dissatisfaction with IBM's service.

I remember hearing about it then, but I cannot now find details of the problems.
> but the more complicated models are run in the cloud

This is a massive problem with home automation tools today. I need to rely on Comcast to stay alive to be able to turn lights on and off in my house? To me, it's an absolute dealbreaker. I've spent more time than I feel like I should have had to in order to control devices I own without any data leaving my LAN. Am I the only one who feels like it's a totally absurd situation?
Why does it need to be a simulation at all? The model is essentially a geometric random walk with number of trials N and probability of success in each trial P, with P varying.

In an additive random walk, the distribution of positions after N time steps is Pascal's triangle with zeros injected every other column and with each row multiplied by one half [1], which is just a shifted binomial distribution (with zeros injected at odd distances on even time steps, and at even distances on odd time steps), with probability mass function of `arw_pmf(k, N, P) = (N choose k) * P^k * (1-P) ^ k - N/2`. For large N, the distribution approaches the normal distribution.

In a geometric random walk, the power of the scaling factor takes on the shifted binomial distribution. In this case, the scaling factor is 2, so the probability mass function is `grw_pmf(k, N, P) = 2^arw_pmf(k, N, P)`. Note that this is _not_ a power-law distribution, and therefor will _not_ exhibit a robust 80/20 rule. Even if you convolve this distribution with an input normal distribution over P, as they do in the paper, you would not get a power law distribution.

The effect of a change in P, which is used to model talent, is to shift the distribution, but not to greatly affect its shape. The shift is consistent with our expectations that greater "talent" results in higher probability of accumulating more capital, though there is of course an overlap in the distributions of two agents with differing talent.

All that being said, I suppose it's possible that the 2D discrete simulation introduces temporal correlations that could alter the population's final capital distribution into a power law distribution. If that's the case, then the power law distribution is due entirely to these temporal correlations, which suggests to me a different insight, namely that the source of inequality is these temporal correlations. In other words, if people who have recently been successful are more likely to continue to be successful, then you will have inequality. Since this seems to describe our world pretty well, perhaps inequality is inevitable?

I have made extensive use of org-mode for many years, and I keep trying to get into org-brain as a way to really have a "digital brain" -- I use org-mode to implement my own horrible version of GTD, to great success. I have tried to start using org-brain many times, but it never works.

I think there's something about having to externalize everything I know that confounds me. I wish org-brain could scan my brain and spit out something I could start working on.
So like banks, but with a much darker recent history of taking the money and running, none of the stability, and none of the insurance. All traded for the dubious benefit of broadcasting transactions to the blockchain, which seems like an empty sop to principle. I don’t care how many times “ultimate sovereignty” gets thrown around like it means anything important outside of a few narrow circles. As a currency Bitcoin just stinks, as an anonymous means of transferring money it stinks, but it’s a great way to shuffle money or rob someone.

If people didn’t think they were going to use bitcoin to get rich quick, they just wouldn’t care. Well, except for scammers and money launderers.
It's more that it's awfully tortuous to use Django without it. The syntax for creating and running migrations inside a Python shell isn't very pleasant and all the documentation assumes you're doing all this from a bash shell.

> We know a lot of seasoned users

It's actually the other way around. Seasoned users can work out how to get round the lack of a shell. Beginners will be thoroughly confused.

Almost always Django. Customers love Django Admin, and when they don't, it's really easy to tweak.

For dynamic apps that don't fit the Django model, I'll bust out Node.js, and for static sites, just a plain Python script to generate HTML files.

Boring choices, but the older I get, the more I'm OK with that :)
> Can anyone share a good IBM experience? I'm honestly interested.

The IBM pc we bought in the 90ies was fantastic.

It had working suspend resume many years ahead of other computers and came with 365/24 free phone support for a year (and the next years was about 50USD). This being was very useful since I didn't have Internet access.

The support team had unlimited time, patience and knowledge and would walk me (15-16 y.o) through any procedure including if necessary: backup, reconfigure disk with fdisk, restore os from backup etc etc. I learned a whole lot from them both technical stuff as well as how to deal with customers ;-)

(And yes, old IBM ThinkPads were very popular IIRC.)

Edit: details.
Super cool idea, although the privacy implications are a little bit discomforting.

Anyway, I'd be interested to know how you're dealing with the depth problem. For example, if there's a light behind you and a light above you, pointing up looks like you could be pointing at either light.
The argument from the linked-to piece is that "IBM is a hollow shell of what it once was".

Happy to see these guys doing well. Got turned onto their product middle of last year and have started using it for all sorts of stuff. Its a great middle ground between an excel file and building a custom app for things. Super flexible with very little learning curve. Girlfriend and I even use it to track which wines we've tried, like, and ratings and stuff for them.

Wear OS by Google sounds like a big bag of nothing to anyone who ISN'T a tech user. At least using "Android" associates it with the platform.
You don't :/

Again at some point there is a part of subjectivity in how you analyze the dataset.

It is still better than having no idea what your users are doing with your product.
You actually didn’t address the theory. The claim was about welcoming “promising minds”. Presumably that means top acientists, engineers, etc

The current systme in America is renowned for being very difficult to get in to on a merit basis. Was this different in the 1950s? Perhaps.

I don’t know if the theory is right or not. And you,ve certainly provided some data to show it *mayg be wrong. But it’s far from conclusive.
An ice skater programme does not use the music as is. The music is edited one way or another to fit the time allocated for the programme. Sometimes a skater uses two or more pieces of music mixed together.

I do not know about the Olympics but I checked with the national ice skating federation, and there are apparently no special licensing fees for ice skating events. Ice rinks pay the usual fees for public performance, though.
I don't think that was quite the same thing, for a number of reasons.

Firstly, just looking at the negotiated opt-out of the ever closer union principle, how legally binding those negotiations were was never resolved. There appeared to be some doubt about whether they would get past the European Parliament, and the Brexit referendum happened before any definitive position could be established.

Secondly, even if they were binding in theory, how would that have worked in practice? For example, 26 out of 28 EU member states are either in the Eurozone already or in principle required to join in the future. Is it really credible that so many member states would always remain honest and neutral on any policy that might disadvantage the Eurozone just to be fair to those with opt-outs (the UK and Denmark)? Similar arguments apply in other respects, the Schengen Area being maybe the next most obvious case.

Thirdly, that issue was distinct from membership of other EU-based mechanisms such as the Single Market and the Customs Union. The latter in particular seemed to be a big concern for the people I mentioned, not just because it precludes negotiating future trade agreements independently as widely discussed in Brexit-related forums, but also simply because while it makes trade within the EU nice and easy, it also makes trade with partners outside the EU a lot harder, because all members are required to impose the EU's standard barriers and tariffs on external trade.

Obviously whether or not you think ever closer union within the EU is a good thing is a personal/political view and reasonable people can reach different conclusions, but if you had thought it through and concluded that it wasn't, I don't think Cameron's negotiations would have done much to affect your logic or your final decision on that point.
From a GPU perspective this is going to require some powerful hardware to drive. If you look at the 3D game benchmarks for the geforce1080 vs the 1080ti (and slightly overclocked, more expensive versions of the 1080ti), the only video card that will actually deliver close to a consistent 60 Hz at 3840x2160 on a SINGLE DISPLAY is a 1080ti. Now multiply that by two screens, and a resolution per screen that is considerably higher than standard 4K.

Nano suffers from the same problem that 99.9% of cryptocurrencies suffer from: no useful information on how an average person might actually USE it.

Google brings various ways you can BUY Nano in order to speculate. I want to see real world usage, I want to buy VPN/Hosting/Alpaca Socks using Nano.

PS Nano is also 100% pre-mined which means one would have to investigate on who holds what percentages of these pre-mined coins. (case in point: Ripple)
I'm skeptical that this a gender-specific issue. Lots of men complain about the difficulty of getting helpful feedback, too. And feedback is hard to provide, regardless of the recipient's gender. You're always walking a line between being sharp enough to be heard versus gentle enough to avoid offence. Ultimately, the recipient is still responsible for the consequences of their actions, and you just have to let them play it out.
I'm not sure that would qualify as 'bootstrapped'.

None of the specifications you cite contains a formal semantics of the language in question; that ought to be the basis on which arguments about simplicity should be founded.
