hyperledger (note: no space) is a linux "enterprise" umbrella blockchain initiative. don't really know.

hyper ledger is a (generic) term for a ledger for the internet blockchain era :-).

Copycats uses the ledger-lite (open source) library [1] - the tagline reads: hyper ledger book for the distributed blockchain internet era; add your transactions one block at a time; transfer crypto(currencie)s or collectibles (e.g. kitties or cats) and balance the accounts (that is, who owns what etc.)

Ah well that put a positive note on my morning coffee. I didn't know that.

But still wouldn't it be valuable to the bidders for Amazon to fix this? Or shouldn't Amazon value better targeting because relevant ads convince users to engage with the platform more? The people selling the coffee filters are still guaranteed my business, just not before 6 months. I always buy from the same seller too so it could be a good opportunity for a competitor to sneak in right at the 6 month mark and make a new repeat customer.

I guess the answer to that is probably "well the system works well enough elsewhere so that would just be hyper-optimization"

> In a 2004 opinion, [Justice Anthony Kennedy] expressed alarm at the practice of extreme partisan gerrymandering but said the court should hold off on outlawing it. He also left the door open to ruling differently in the future, as long as lawyers provided a suitable way to measure when gerrymandering goes too far. He said that without that measurement, the court runs the risk of becoming too involved in a decision-making process that is legally mandated to state legislatures.

What the elected, Republican majority legislature voted for is not "crass disregard for the democratic process". It's actually the democratic process. If the legislature passes a bill that's unconstitutional, then it's up to the judicial branch to rectify that.

By population, NC is a 50/50 red/blue state. Even by county, which is what a non-gerrymandered legislature would look like, it's all red outside of Charlotte and Raleigh, and 50/50 in places like Greensboro or Fayetteville.

I'm against HB-2 as well, but it's up to the judicial to rectify that.
It's one half of it; Lightning also needs a "time lock" mechanism to somehow execute payment for the committed balance of the channel if one party unilaterally abandons it. This is quite complex involving both parties holding a delayed and revokable payment from the other party.

In the case of a game, this might be simpler since you can have each player sign their own moves and the other player's last move, so that you can always broadcast your opponent's last move if they quit.
So. In calculus both the derivative and integral are linear operators:

D[a*f(x)] = a*Df[x]
D[f(x)+g(x)] = Df(x) + Dg(x)

and the indefinite (without limits) integral is an "antiderivative", right? I.e. y(x) = I(f(x)) is the solution to

D[y(x)] = f(x)

Here's the problem: there are multiple solutions to the case where f(x) = 0. Indeed, for any constant y(x) you have

D[y(x)] = 0

This is why you're drilled in engineering classes to always add a + C to your indefinite integral. The solution to an indefinite integral is always a class of functions -- the part without +C continues to be linear, but you have to tag that along.

This is also why Initial Value Problems like

D[f(x)] = g(x)

always need an initial condition.
I'm not sure what you mean. Unless I am completely ignorant of the way financial markets work, the exchange is exchanging between two parties, and skimming off the top. They do not care what the price of Bitcoin is, as long as there is trading volume. They do not lose money in the event of a meltdown. The people selling the put options do.
> To me it's like the limitations of first game consoles (1kB usable RAM for the NES). Having great games work on it needed quite crazy coding skills and several hacks to use less space.

That’s not a fair comparison, in my opinion. A billion NES consoles can operate in parallel, without affecting the performance of other consoles. It scales perfectly. For a shared blockchain, however, performance deteriorates for you when someone else plays. And it doesn’t even have to be the same game. I mean, if a single game like CryptoKitties can reduce performance and increase fees, how will it look when there’s 10 games out there, or 100?

> I always find it odd that such a tech-craving population as HN readers always seem to miss the bigger picture.

I’m not saying this can’t be solved in the future. I’m talking about the present motivation for building blockchain-based games. Why can’t we critique technology just because it has the potential to improve in the future?
Gold did not lose value. It locked you in at the price you paid in that time's dollar. If you then try to swap that locked in value for a dollar at a later date that has a higher value, you will suffer the imbalance.

It stored your value. It's the dollar that gained (or lost) value. You're attempting to move back into the dollar afterward, when the dollar's value has shifted.

What you're describing is that, as an example, a mistake was made by locking in your value by buying gold at a weak 1980 dollar price, then the dollar gained significant value in subsequent years, and then you're again trying to move back out of gold and into the dollar later (ie exchanging gold for dollars) after the dollar has climbed (while your value in the gold was set at that weak 1980 dollar). Your loss is the difference between the two different values of the dollar at two points in time separated by decades.
There's a lot to digest in this article:

1) Absentee landlords are terrible. I can't say I know what the solution is, but perhaps simply lowering the price of the houses until the (low income) workers could afford to buy and therefore take stake in the community is preferable?

2) Unfortunately the sprawling layout of Hemet in particular is unconducive for creating the kinds of businesses that could at least mark the beginning of a more dense mixed use area. In this case there will have to be pain to raze some of the houses at the very least to help things go in that direction.

3) Broken window effect seems to be in full force with the absentee landlords only throwing fuel to the fire. Ideally the city would help some of these residents sue these landlords to resolve some of these issues, which would help slow the downward spiral of non-maintenance by the residents.

"This is all part of the long-standing "taxation is theft" meme that infected the USA in the late 1970s and early 1980s"

No, it's not. This is all part of the scam politicians have been running on the public for decades. Namely taking taxpayer money earmarked for specific purposes (i.e. maintenance) and then not using it for those things. Then they turn around and say "we don't have enough money, we need to raise taxes to pay for these unforeseen costs", even though the costs were completely and entirely foreseeable. Also, let's not forget the egregious waste on construction that is rampant in publicly funded projects, with NYC being the worst offender of them all.

2018.01.09 Issue with TLS-SNI-01 and Shared Hosting Infrastructure
I have a question for AI/NLP experts (and I might use the wrong terms).

When our voices are processed in systems like these are the results compared to a corpus of our own speech, a local (geo) population, or language speakers as a whole?

I’ve been curious how slang and people with poor grammar affect results of other users. Will we start seeing “thicc” instead of “thick” and “dat” instead of “that” over time?

One of the reasons I’ve been pondering this (anecdote alert) is that I frequently see iOS dictation spelling bizarrely.
the crass disregard for the democratic process on display in NC is a model coming soon to a state near you :(

It's not just the democratic process, but more generally the rule of law. The GOP has gone into crazy territory with their "ends justify the means" strategies. Look at the support of Roy Moore. Party over everything. Disgusting.

As you might imagine, it is possible to consider this as a purely mathematical problem and to thereby come up with measures of gerrymandered-ness. It is a widely studied field. e.g.:

You're right, it isn't just the criticism.

Armstrong advised Reagan, Thatcher and numerous other administrations over the past few decades. He has been behind the curtain.

His computer system has been accurately forecasting long-term socio-economic trends and their apices since the eighties. This is what the banks wanted.

When Armstrong turned the banks down, they sought to forcibly acquire the software and utilized government to squeeze him. The story continued on with illegitimate confiscation of billions and civil rights transgressions as Armstrong was jailed for years over contempt of court because there were no legitimate charges that could be brought against him.

So yes, there's definitely a history that makes Armstrong a target. The deeper you dig, the more it makes sense why The Forecaster was effectively blocked in the US and others have no problem.
I think the current analytical mechanism to achieve balance is by measuring the “efficiency gap.”

Fivethirtyeight.com people have written a lot about it (including why you can't simply write a program and go home, just like you can't for most political questions). They also have an ongoing podcast series that talks about the issue in great detail 'The Gerrymandering Project'.
The typical standard is "are Democrats disadvantaged by this?" If so, gerrymandering.

The UK (which is -- at least for the moment -- usually considered "developed") doesn't require ID to vote.
I installed the recent kernel release from Ubuntu, but the tests still working fine.
> Literally every other developed country (and most undeveloped countries) in the world require ID to vote

Well, the UK doesn't. And most other developed countries have proper national mandatory ID systems where everyone has an ID. People would complain a lot less about the ID requirement if the ID was equally easy to get for all voters, which it isn't.

> 1. We see no problem in dongle jokes

Who is 'we' here? You think most Americans have a problem with dongle jokes? Or you mean to say that most or all Europeans don't have a problem with dongle jokes.

> 2. If someone would see a problem with it and complain, those complains would be ignored (because we see no problem)

This is when you end up with Uber, where these complaints were ignored and they eventually ended up with Susan Fowler incident.

The company fired the woman who complained because their servers were getting DDoSed.

Look I know what you're saying, it isn't that a day passes by when someone on the Internet, Europeans don't remind Americans (And many Americans remind themselves) that Americans are very prude compared to Europe.

But what you're not doing is understanding the problem here. The problem isn't the 'prude American culture', rather, there is a civil life culture, and then there is a work culture. The complaint feminists have made is that work culture needs to be more welcoming to women.

So the question is 'What constitutes as welcoming work culture?'.

Saying "Hurr hurr, we are Europeans, we don't have problems like that" is just sidestepping the issue.

Are European workplaces completely welcoming to women, as European feminists would like it to be? If not, then how are you dealing with it?
I agree with you, however, how would you propose that we ensure compliance in respect to money being used for intended purposes?

Ask HN: What are the cons of DAGs as compared to blockchains?
Crypto currencies based on directed acyclic graphs (e.g. IOTA) seem to solve nearly all of the biggest problems with blockchains -- scalability, low or 0 transaction costs, no 51% attack, no need for miners.

DAGs cannot be used for generalized smart contracts, so they are not a competitor for Ethereum. But do they have any disadvantages as compared to Bitcoin and other pure cryptocurrencies?

I assume I'm missing something, because otherwise DAGs seem too good to be true. And so far there has been little attention paid to them by the crypto ecosystem.

> The web package definitely originates at the origin, but is it up-to-date? While I assume the web packages have expiry dates that the CDN servers would respect, this doesn't give the full control that Cache-Control headers do.

I think it's the other way around - webpackages include Expires: headers for each resource that are signed by the origin, so the browser decides whether to trust it or not, or maybe to render it anyway but show a staleness indicator. But if you're using a CDN, the CDN implements caching on its own (hopefully following the origin server's instructions or the customer's instructions in a control panel, but no guarantee) and all headers are entirely controlled by the CDN.

> And in terms of functionality, does the AMP web version have all the functionality of the normal site?

On the technical side, this is now the origin's decision, not Google's - they can include whatever functionality they want or whatever links they want in the webpackage. It's not really different from having a mobile site that has a "View full site" link, or worse, doesn't have one and also misdetects your browser.

I think I agree that in practice it matters a lot what people choose to do, and whether Google adds restrictions for what sorts of webpackages count as "AMP" for the purpsoe of special treatment on the search results page.

I don’t see how any rational individual could limit this criticism to only the Democratic party.
And the concerns of bias in the algorithm could still be there. As would the fear of hacking. Neither seem as big of an issue as flat-out intentional gerrymandering and could be mitigated by open review process.

But it's unprecedented which makes it hard to enact without a lot of momentum.
People can congratulate themselves as much as they want, but the fight won't be won until VP9 is actually (technically, not legally) superior to HEVC in terms of the available implementations.

Having the luxury of not caring about software patents in the least, I'll stick to x265, thanks.

> What the elected, Republican majority legislature voted for is not "crass disregard for the democratic process".

The fact that the judiciary has the power to stop them does not make what they did any more or less acceptable. Gerrymandering the state specifically to subvert the will of the voting population is crass disregard for the democratic process.
I'm sure you'll get multiple answers, but Bitshares solved these problems in 2014 with Proof-of-Authority (aka Delegated Proof-of-Stake). Seconds between blocks produced, and the transaction fees are like $0.005 or something ridiculous.

The code was forked to create the Steem blogging platform, and now EOS is in development to essentially back Ethereum-like smart contracts with the DPoS model.

Ethereum is trusted, and Vitalik is a great project leader. If they can solve distributed smart contracts with his new plans, that would be huge. For now, it seems like the middle ground is where it's at.
People think it already costs too much to use and the prices keep going up as it is. So then it comes back to political situations like Christie ending a project in the name of lower gas prices.
No, it does not sound familiar because I’m a hardcore do it yourself guy, and one of the reasons that is so is because I seek masters in other professions to teach me. That’s how I know what trade-offs they do or do not make, and following an insight by a family member that we (as a profession) can never get these damn computers to work correctly I’m becoming more and more discusted by the truth of it.
That meets the /digital/ criteria but not the /cash/ criteria. consider that there are banks and accounts that you can't wire to, or that an account can be frozen. cash & bitcoin don't suffer this. there are a number of desirable properties that bitcoins have, and some downsides as well - digital is only half the equation.

There was a bit of research just recently that I believe was posted here about the RDA values for vitamin D being far lower than they ought to be due to statistical errors in past studies. The errors resulted in underestimating the levels of vitamin D necessary to avoid negative health effects pretty dramatically, and they recommended changes to health and diet recommendations ASAP. I believe that they estimated that most people should probably be taking 10,000 IU/day supplementally.

Personally I was diagnosed as vitamin D deficient a few years ago and my doctor prescribed gelcaps that were 50,000 IU to be taken twice a week. Upon switching doctors, my new doctor noted the deficiency in my records and said that she recommends everyone in my state (West Virginia) take vitamin D supplements as nearly everyone is deficient. And that was by the older, lower, standard. She didn't renew my prescription but I have begun taking 10,000 IU/day OTC supplements, especially after reading that research I've been considering doubling up.
> Quibble: Is it actually 'healing' if the depletion rate is decreasing? The hole in the ozone is still getting bigger. It's just getting bigger at a slower rate.

Ozone is create in the upper atmosphere by UV light bombarding oxygen, among other mechanisms. The depletion rate is decreasing, but it's less than the creation rate, so the hole is healing. Even without chlorine, the ozone also decays back into O2 naturally.
First define what goals are "fair" or "balanced".
Software I use daily:

- Gmail

- Google Search

- Android

- Firefox

- IntelliJ

- OSX

- Slack

Except maybe for OSX, none of those fits the definition of "barely maintained" (I'm kidding ofcourse - obviously OSX is maintained too!). I suspect none of it is "developed by multiple contractors" either (though, why would that automatically imply "crap"). None of it is "barely running" - they might have some issues, but they run. Some of them, impressively well (take Google Search, or Gmail. They have outstanding uptime; Slack isn't too bad, either; and both IntelliJ and OSX run rather well too).

One of my former teacher used to say; "a program is like an airplane; it either works or it doesn't. You can't say that an airplane mostly flies". If you take that worldview, sure, all software is crap. But that worldview is deeply flawed IMO, in a very practical sense.
