North Americans eat too much of everything. Nearly every diet "works" because by cutting out some branch of food you generally end up eating less. The science behind meat v. carbs is a total edge case. We are talking and +/- 10% chances of premature cancer, or heart disease, or whatever other old-person malady we are trying to prevent today. What matters more than any specific food is not being fat. Eat less. Exercise. Be thinner. That will do far more to prevent premature disease than any specific diet.

Rather than a meat tax, I'd rather see better government support for healthy lifestyles. Employers give sick leave. They should also give exercise leave to prevent disease in the first place. (Mine actually does this, 4 hours per week paid exercise time.) And tax deductions for gym/fitness center memberships is the lease that could be done.
UBI proponents should be cognizant of stagflation. During the 1960s and 1970s, demand-side fiscal policy was based upon the Phillips curve, an observed correlation between low interest rates and low unemployment. After the oil supply shocks, this observed correlation began to break down as interest rates were lowered to compensate for the rise in fuel costs. By the late 1970s the US was experiencing stagflation, a combination of low interest rates, high inflation, and high unemployment, which should have been impossible according to the Phillips curve.

In reality the Phillips curve was too simple. What was happening was that since wage increases came to be anticipated due to the consistent low interest rate/moderate to high inflation environment, producers would preemptively raise prices to soak up all of the wage gains. This led to a wage/price spiral with no actual improvements in productivity.

Eventually stagflation was ended by dramatically raising interest rates and triggering a nasty recession.

UBI could lead to stagflation because the income allotments and any increases would be according to some formula known ahead of time. This means that producers could anticipate demand and simply raise prices to soak up any income increases.

Something to keep in mind when devising these systems.
I like this idea! Bitcoin is broken by design: people don't spend their coins, and you can't blame them, they would be silly to to that, because Bitcoin is a deflationary currency. But this universal basic income idea would actually make people spend their money and we would have a thriving economy. The big challenge is: how to prevent fake accounts?
I do strict Keto the first 6 days of the month, which is where I was getting the 20% from.

The rest of the time, I do my normal diet of mostly fast food, too much candy, and no exercise. I might drink a little more water than I used to in this period, but no major changes.

Sorry if there was a better way to phrase this.
You don't know stress until you've had a divorce due to all of these after hours spent studying the latest fad. That is real stress and that happens to a lot of programmers. I am dealing with that personally, I have had 2 kids and I have done the best I could. Newborn stress is nothing compared to a divorce from a long term marriage.

People probably did. Plus it was ultimately decided by a bloody civil war that still has lasting cultural and mental consequences to this current day.

So do you really believe eating meat is at the same level as human slavery , or is it an argument to ridiculousness.

My point was we should not ignore the human cultural consequences in our logical calculus, humans aren't purely rational actors .
A lot of these are independent from salary, however, and usually uncorrelated. I pretty have all of these at my current job, certainly the best I've ever had at any job (and I'd throw in a #5: Perks). And my current job, at a Big 4, also happens to pay by far the most of any job I've ever had too.

I would certainly never sacrifice any of these for a minor bump in pay, but oftentimes you don't have to sacrifice any of them even for a major bump in pay.
With what I'm talking about, you aren't going to see 1 for 1 examples of cause and effect. It's more that having these measures in place will necessarily prevent certain types of measures from even being considered since they've been excluded from the Overton window.
With the current difficulty level isn't the '6 block standard' a bit dated unless we're talking about a transaction that is extremely valuable.
Automation has put millions out of their jobs, and is growing explosively. They can't all become skilled workers - we don't need another 30 million Engineers even if they could all do that.

So folks work at McD's and the feds pretend its 'employment' but nothing like they used to earn.

Ask HN: Bitcoin futures scam?
I don't understand Bitcoin futures, or how futures work in general. The media keeps publicizing how this now gives "legitimacy" to Bitcoin, like it needed it. It lets people bet on Bitcoin, but they don't even own actual Bitcoins? How is this not a Wall Street scam? Please explain.
"Most just piss their life away."

This is totally not snark: how is this different from people without ambition who have a low-end service industry job and no ambition to do more than wash dishes or pump gas?

Why would there be anything more dignified in an old man washing dishes in a restaurant over an old man just drinking his days away? Neither is what I aspire to, but the latter feels more honest to me.

In other words, what I try to wrap my head around is: who cares how someone else wastes their life, if that's ultimately the big-picture goal they choose?
Bijstand in The Netherlands :

- 467k on a ~ 17M population

- € 1000 - € 1200 a month

- all adults with no income and too little assets can apply

- you will be forced to find work or income, but this is trivial to sabotage

When you are in the 'bijstand' income-bracket you are also eligble for rent assist and health insurance assist, netting another couple of hundreds.

edit: introduced in 1965.

edit2: population 20-65 yrs is actually ~10M, so 1 in 20.
They left out the part where the CIA gave them all their weapons.
If "bijstand" is anything like the Danish "bistand", then it's nothing like UBI. It's nothing like UBI because it comes with infinite strings attached that in practice gives you no incentive to get a job. To see a rather nice explanation of UBI and it's differences to current social security schemes watch this.. https://www.youtube.com/watch?v=kl39KHS07Xc
You do in order to enable UBI directly in the protocol, which is the goal of this paper. You can't regularly distribute Bitcoin to all users without first acquiring it. I think this is one of the few examples of a new coin that actually is needed in order to accomplish its goals. Of course, whether it actually does that successfully is another argument entirely.

Nassim Taleb says Bitcoin can’t be shorted properly as futures debut
> Main problem, how? Wouldn't doing what you say feel incredibly limiting since you know you could be enjoying so much more?

More limiting in the sense that I would have fewer options for wasting time, yes. More limiting in that I'd be forced to engage with media I had on-hand, yes. More limiting in the sense that I'd somehow be worse off after, say, a year of that? I very much doubt it, and expect the opposite would be the case. Little of my use of the Internet is productive, what is productive is rarely more so than, say, reading, and mostly it serves to take time from activities that would at least not be any more a waste of time, and may well be more improving (including simply sleep).

> Do you do what you describe?

No. I'd cancel our home Internet today if it wouldn't be incredibly inconvenient for my wife. She's a teacher, and she does and is expected to do way more work stuff online in the evenings and on weekends than I am as a developer, unfortunately.
First, I know a lot of vegetarians and non veggies, and I never seen one of them "trying to impose their habits on others". It's like saying gays are trying to convert straight people.

Worst case scenario they will tell you what they think is right. But we all do that, it has nothing to do with meat. Hell, try to have a discussion about driving habits and you'll see everybody will tell you what to do.

Second, yeah, taxes are probably just motivated by money, and trying to get veggies to support it.

But even the worst detractors of the theory agree that more than 14% of green house gaz is animal agriculture (https://www.skepticalscience.com/how-much-meat-contribute-to...). Those numbers do not include transportation, wrapping, cow farts, water consumption, soil pollution, and exclude deforestation done for animal agriculture purpose.

So there is something here. There is no need to fight about this. However a sane debate seems in order.
I think the ability to debate pseudonymously is very important. But I think it's also totally reasonable to do so under your real identity, if you feel comfortable. Lots of people blog, for example. In many ways, Facebook serves much the same purpose as a blog to me, but with better discourse.

Also, real identity carries weight in a discussion because you're socially accountable for your views and conduct. Now, again, I'm privileged to hold views that are socially, politically, and professionally acceptable in the spaces I inhabit,even if they're not often fully shared. But I also don't think that's coincidental.
This is exactly my experience as well. I have discovered (pun intended) more musical artists and genres than I ever would have found in the olden days of spending countless hours downloading and curating my own musical collection that rarely ventured out of my genre comfort zone. Just looking through my more recent playlists there is so much niche music that I would not have known about with the itunes model.
Returns from greater fools? I'd better stay without profits than participate in a pyramid.

Ok, I can understand how a bloom filter can be replaced by a neural network predictive model. You could actually train it while stuff gets added. This would make adding somewhat more expensive, but ...

Ah so it appears they're advocating using neural networks as index functions to sorted arrays (hashmaps are simply sorted by hash instead of by something in the data).

So what they do is they take a FIXED set of data that you want to quickly lookup in, already sorted, train a model (2 layer 32 width, relu activation is one architecture, but they also train sequences of models, HUGE changes to error (as the cost of max and min error are huge, you minimize max error rather than average error)).

They have the following brilliant insight : an index over a database (which gives the position of the data given the search key) is a CDF (cumulative distribution function) ! That's brilliant ! Of course it is !

And of course, this is Google. Once you have an index trained (which is a linear operation), you can translate the neural network model directly into C++, and compile it into machine instructions that don't depend on anything like tensorflow libraries. The resulting code can be pasted into anything you want. This may work fast, but seems less then entirely practical ... although I guess you could do the same in Java far easier and you could just include that code.

And that's how it works in finance. You are hired to do a job. For boat load of money. When that job is done, you are fired. And no one cares because working 3 years for guaranteed $800k/year + $500k bonus that you will probably get is worth being fired on a 3 year + 1 day anniversary.
See above, but I don't know of any other coin that can do the job that this one is attempting to do.
The entire point of universal basic income is that it's universal, not limited. Other forms of social security (including no-strings-attached social security for those unable to participate in society, such as bijstand in The Netherlands or leefloon in Belgium) are not intended to replace pensions, unemployment benefits, disability benefits, benefits for children or parents, public housing, subsidized tuition, tax exemptions, a tax free personal allowance, and so forth and so on, whereas UBI is intended to function as a replacement for at least a large chunk of these various schemes, not an addition. That changes the entire dynamic. Is it a good idea? Frankly, I don't know, but you can't point to abuse of one particular form of social security and say "see, universal basic income doesn't work!" because it's not nearly the same thing.
Futures are a derivatives. You can use any currency or collateral to trade a derivative. Why do you want people to own bitcoin in order to bet on it?
What are the tax implications of playing with Bitcoins? (disclaimer: I have no desire to do so, just wondering about it). Say I bought some BTC a couple of years ago, and now sell them at some exchange like Coinbase or Coinmate or whatever. Do these exchanges report 1099s to the IRS? If not, how will the IRS ever find out? (I'm not proposing cheating on taxes either, but just curious about what goes on). What if you just keep the gains and keep quiet?

Ha! There are maaaany opinions in this thread, but I will add mine.

I'm not a fan of writing stupid mocks. That doesn't give me much confidence, and spending time on tests is mostly about building ones confidence. I very much prefer running the program end-to-end with defined inputs, and checking its outputs.

Whether that's database, file on disk, or REST api. I write python nosetests that prepare the setup, run golang program, run the checks, and tear down the setup. Sadly, normally it's hard to get golang code coverage for end-to-end tests (aka integration tests). This is what I usually do:

> So do you really believe eating meat is at the same level as human slavery , or is it an argument to ridiculousness.

I'm just using humor to state that if an issue is important, there will always be those type of argument. We should not stop at them. Taking them in consideration is obviously the right thing, but those can't be definitive show stoppers.

Otherwise the status quo will always win since by definition all our systems are built around what we are doing right now.

I realize this, but if mass unemployment ensues, where will the money for UBI come from? It can't be printed from thin air and it simply isn't fair to take from those who sacrificed their time and efforts to build wealth, only to have it taken away.

My hint at the trades (HVAC/Plumbing/whatever) was that the supply will be incredibly low in the next decade or so, when many of these workers retire, but their demand will be higher than ever.
Plenty of us find value in a currency that isn't controlled by a central authority and isn't subject to inflation. We're betting others who value saving over risking their savings in the stock market will also value such a currency.

Plenty of us believe there's potential in programmable money. Certainly more potential than yet-another-social-media-platform-selling-ads.

If Segwit adoption (~12% after launching toward the end of August) by 3rd parties is any indicator even if lightning released today we wouldn't be seeing huge benefits for months if not years.

There is a certain elegance to increasing the block size as it allows you to continue using the chain as you've been using it for years (on-chain transactions). As a bitcoin community member for nearly its entire history myself and others have worked hard to get the level of merchant adoption we enjoyed in early 2016. Today bitcoin is accepted in less places than it was 2 years ago and transacting with is is a luxury only reserved for us privileged early adopters. It was never supposed to be this way.

We have two issues with Subversion:

- it requires a certain discipline: we need branching in our workflow and this is handled mostly by convention in a subversion repository. We have "branches" that were created by less careful colleagues by copying subdirectories of trunk to the branches folder.

- all the tooling developers fled to work on making git bearable. It seems that there is good money in sugarcoating got and none in making good tools for Subversion (awareness of branches in Jenkins, decent code review...). We have a budget, but that does not compensate for the lead that git has in that regard.

Other than that, subversion fits our needs. It just works.
Looking at the demo (why does it show the demo login details to have us copy-paste it, instead of autofilling it or even auto-logging in?), I feel like they tweaked the mobile interface a little bit and serve it for the desktop, and called it 'responsive design'. Basic actions like 'Add new books' are hidden in a hamburger menu over at a corner, easily overlooked on a desktop, and the menu fills up the whole screen when expanded, despite having only four options.

I like the idea, but an explanation or a FAQ would be much more useful than a small list of vague bullet points. It looks like it takes PDFs and epubs and serves them as HTML - but PDF conversion is particularly tricky and prone to failure. Are there options to tweak the conversion like in Calibre, to work around badly formatted PDFs (which seems to be most of them)? How does it handle figures, or tables that are too large for a given mobile screen? Can it fetch covers and/or metadata for books if necessary? Answering some use-case questions like these can give users a better feel for the scope and goals of the project.
