Although interesting in its own right, Bitcoin's energy consumption is in no way a good basis on which to judge its social value.

Bitcoin is fundamentally an asset. A useful analogy is to think of it as gold. Gold can be used to make payments, but it is not convenient. Same goes for Bitcoin. But they are both useful as a robust way of storing value.

Maintaining the Bitcoin network costs energy, but almost nothing else. Given Bitcoin's price history, it's safe to assume that Bitcoin's total energy cost is a tiny fraction of its current market cap of around $150b. Now compare that to the social costs of protecting gold, which probably has an over $7 trillion market cap. Wars were fought and lives lost for its ownership.

In conclusion: a large and liquid crypto asset like Bitcoin provides a much more advanced solution of value storage and transfer than traditional physical assets. Its net social benefits should be orders of magnitudes higher than its energy expenditure.
You want exposure to 50% of the upside: this means you want exposure to 50k worth of each stock. You don't want to lose more than 100k total, and are ok being wiped out if both drop 50%.

Seems to me like you'd want to buy 25k worth of call options at a 50% strike price. The options would cost 25k and would reflect shares worth 50k. You get exposure to 50k of shares on the upside, but your loss is capped at 50k total, which is twice as good as your deal. All you need to do is pay interest.
Dunno, that seems a bit to regular. Humans weren't that stupid and rivers change all the time.

Seems much more likely it's something really unusual. Like say the Mediterranean basin and the resulting Zanclean flood. Back before humans were in North America it was a giant fertile basin with numerous rivers. Then one river that happened to come from the Atlantic ocean started to make some progress with erosion and kept getting bigger. The feedback loop turned into something that embarrasses Niagara fall by many orders of magnitude.

If you lived in the Mediterranean basin this would have made quite an impression. I believe this event was well depicted in https://xkcd.com/1190/ or https://blog.xkcd.com/2013/07/29/1190-time/

As big as that mega flood was, there have been others and certainly seems like very good source material for the numerous flood myths.
First I thought dapper, but that was google, and it was about distributed tracing... but sounds very close (and have some relation - e.g. you need sidecar to capture network traffic, and propagate tokens for distributed tracing - that is unless you want to change your source code to do so)...
Correct. See...

I disagree about for loops, you actually end up using these quite a lot in vhdl/verilog (with understanding about what logic you are going to end up with), if you want to do the same operation on multiple things:

input [NUM_OF_MULTIPLIERS*32-1:0] a_in,
input [NUM_OF_MULTIPLIERS*32-1:0] b_in,

output [NUM_OF_MULTIPLIERS*64-1:0] mult_out

reg [31:0] tmp_a, tmp_b;
reg [63:0] tmp_mult;

always @(*) begin
mult_out = {(NUM_OF_MULTIPLIERS*64){1'b0}};
for (i=0; i<NUM_OF_MULTIPLIERS; i+=1) begin
tmp_a = a_in>>(i*32);
tmp_b = b_in>>(i*32);
tmp_mult = tmp_a*tmp_b;
mult_out |= tmp_mult<<(i*64);
end
end

Would give you NUM_OF_MULTIPLIERS multipliers. If you wrote each multiply out, it would be more code and also wouldn't allow you to parametrize the code.

"Either there is something in the way we as a society and industry educate, hire, manage, and promote women".

I would add raise and socialize as kids to the list, but to me that's clearly part of it.

The entire evolution of a person from baby to adult is moulded by society, which makes it pretty ridiculous when the enlightened techies want to solve the lack of women in tech by only "fixing" hiring and promoting. And management, if we're feeling generous.
Thank you for the extra information, looks like my info and hence opinion is not up-to-date.
Financial sector does not produce 20% of carbon emissions. They are maybe 0.1%. The act of trading on exchanges is significantly more efficient than the act of trading on blockchain. Because there really is no need for an untrusted ledger when there is the USG certifying that the NYSE and NASDAQ will not execute erroneous trades.

Bitcoin does not eliminate the idea of fiduciary duty. Bitcoin holders still expect bitcoin loanees to trade and operate in their financial interest.

Yes, I understand this idea, and it is what I mean when I say that the rules of operation of the mixer invalidate the link -- in reality -- between the coins that you got from a mixer (post-mixing) and the coins that were given to the mixer (pre-mixing).

But the protocol doesn't reflect the reality of the mixer; the mixer is built on top of the protocol. Within the protocol, those coins are still linked, allowing perfect tracking of coins as they pass through the mixer.

You can argue in court that your kingpin coins aren't really kingpin coins, but you'll always be hamstrung by the evidence. What you really have are plainly-labeled kingpin coins and an admission to purposefully receiving contraband.
> Reduction in inequality between men and women has an inverse relationship with rates of women in engineering. The countries with large inequality between men and women like Indonesia and India have some of the highest rates of women on tech. Egalitarian countries like those in Scandinavia have the lowest rates. The idea that low rates of women in tech is a product of inequality and discrimination is hard to justify in practice.

That sounds like a cherry-picked example. For example, Eastern Block (USSR and similar countries) had a lot more gender-equality than the Western Block (like US) and has way more women in STEM.

Your second quote seems out of context and doesn't occur in the paper you cite.

Your first quote says "sensing range below 10m".

Yes, it is possible to make long range 60GHz systems-- largely through antenna gain and lenses. Yes, we could build an entirely different radar to track peoples' gross movement--- and could have 20 years ago, too-- but that has largely nothing to do with the original system or your original claim.

If I wanted to image people at low resolution through a wall, 60GHz is about the last thing I'd pick. Drywall alone has an attenuation of about 3 dB/cm, and remember we have to cross the wall twice. You run out of loss budget really quick. Suggesting one can go 10x as far (10000x power alone) and through walls is... creative.

If you want to track people through a wall, use UHF. It works pretty well and is pretty easy.
That is a side effect, not the purpose. Millionaires can use Bitcoins to move their wealth too. I'd say even for a transaction of $1,000, it is often cheaper to move in Bitcoins.

On the contrary: the purpose of private banks is almost exclusively for billionaires to move their wealth around, while externalising costs to all of us. Many financial market interventions in the past are the society bailing out billionaires who bet irresponsibly and cannot bear reducing themselves to millionaires.
There's a very simple solution here that avoids any and all bias and hidden agendas: simply make everything transparent.

- Users get to create their own profile. For instance in your profile you get to selected whether you would like to see content geared towards men/women/any. And this would follow for a whole slew of other topics, similar to the opaque profile companies are creating on users today without their consent or input.

- All recommended videos have all their profile tags openly shown. And the reason for recommendation is also completely open.

The cool thing about it is that this also works really well with the current neural network based recommendation systems since they output a weighting of things. Simply transform those weightings into a nice output and the user can see exactly what's going on and exactly how they're being viewed. As a nice aside this would also remove a big chunk of the incentive for increasingly aggressive spying as companies try to get ever more extensive profiles on each and every person that uses their products.

One downside here is that users might not be consciously aware of their own preferences. This could again be resolved transparently.

The literacy test was to gain citizenship after you had already been granted permanent residency, so while they wouldn't be eligible to vote in federal elections, illiterate people would still enjoy almost the benefits and rights of any other US person. Almost anyone can learn to read, it's not that hard, almost every 5 year old learns to do it. If an adult in the early 1900's wanted to be a citizen, but were blocked by a basic literacy test and still didn't learn to read it's because they weren't interested in putting the effort into it (there are people with severe disabilities, that is a totally different situation and i'm not addressing that). Of course it's way easier to be born rich, but if you think someone who is poor but motivated can't learn to read you are insulting their intelligence.
When we say inconsistency we normally mean a small difference; my understanding is that physics is missing 75%+ of the stuff of the universe that is required to make the sums add up. That's not an inconsistency, it's a dissonance.
> Bitcoin does not compete with literal credit card transactions (although some use it like that today). ... So compared to shipping and securing gold, Bitcoin is quite cheap!

I haven't heard the tagline "Bitcoin - it's cheaper than moving around gold on warships" yet. So far, Bitcoin has always been advertised as a new form of internet payment and a new decentralised currently for everyday use.

It's also the very point of cryptocurrencies that there are no intermediate agents, like central banks that could make up the lower levels of your stack.

So the usage patterns that Bitcoin was marketed with absolutely put it in competition with visa transactions.
I think bitcoin won’t be able to compete long term because one way or another, it’s users have to pay for the tremendous energy expense.

I hope we recognize this rather sooner than later, such that we can stop wasting so much energy.

> But for the German political landscape, where political parties are publicly funded to ensure a somewhat level playing field (at least in theory) this is a complete perversion.

Public funding is only a part (about ~30%), donations and member fees contribute far more.

As for that being totally new, I don't think so. The AfD is the only new addition in recent years which changed a lot and still takes adjustments (though I don't know if it's actually that different from the Greens way back when - only they aren't conservative, so they wouldn't have used the patriotism angle and websites weren't a thing).
It's historic in the sense that it's one of the first interstellar objects we've seen. But these things are almost certainly not rare; they only seem so because we've only recently become able to detect them. In 10 years sightings of interstellar objects won't even make the second-tier news feeds.
Good point, I wonder how they define "protected group". If that's https://en.wikipedia.org/wiki/Protected_group then it is slippery slope in some situations. E.g. when you decide to work with Chinese companies should you take into considerations how China (as country) is behaving with Muslims in their country.

Buy $10M worth of bitcoin, and then sell it again the next day, and we'll see how much you lost (on average).

I'd guess you'll lose far more than doing the same with gold, because the market slippage due to lack of liquidity far exceeds the cost of those vaults, banks, and guards.
They could make the algorithm customizable and let the user to control it. That would be much better than the current blackbox where you get uninteresting stories promoted because of misclicking once, and have no way to tell the algorithm about its mistakes.
Yes. If you don't trust your developers to use controls like kubectl, you have a bigger problem.

And I'm sure it's easier to throw money at a project like this than to actually fix that problem.

Not on a daily basis, but I see ads for scams on youtube as well.

So the owner of the content payed the thief (indirectly, but still) for placing an ad during performance of the stolen content. And youtube couldn't care less, as long as money moves...

And that is the problem, isn't it? If the majority had been left to make decisions, things wouldn't have changed. Things only changed because the minorities spoke up and convinced the majority that change was needed. This is why discussion, debate and dissent are necessary, because opinions should percolate and attitudes should be exposed to contrary influences.

I think a large majority of the arguments here are folks looking at this through an engineering lens, trying to optimize the workplace at the cost of minorities or discriminated groups, but shouldn't this be the other way around? Workplaces should instead be optimized for everyone to be able to work there, and inclusion is an important part of that goal.

The ideologue does what the ideologue does, and campaigns for change. That's as you said, their role is to believe that change is possible, and that their efforts will contribute to bringing it about. And the whole point of theirs is to reach out to the non ideologues. The fact that there's some bad actors out there that either die to incompetence or maliciousness make a mess of it doesn't mean that the ideology is flawed.
If you have an opinion (any opinion really) about a race or a national origin, that makes you a bigot, yes. Non-bigots don't have opinions on a color of a skin, nor a place of birth.

Those things are not chosen by an individual and therefore should not be discussed nor should the individual be generalized based on them. You can criticize an individual based on their action regardless of where they're from or how they look like. As soon as you start generalizing everyone who looks like them / is born in the same area as them, you become a bigot.

There, you were already so close to being self-aware that I hope I helped you achieve awareness.

> This whole comment section tells me that almost no one on HN really understands OOP.

Or maybe it tells you that the benefits of OOP are different from what they're theoretically supposed to be. What I read from the thread is that there seems to be significant psychological appeal to some in the noun-verb way, and OOP (perhaps unintentionally) satisifies that need. (And that helps me understand the frequent "Julia needs a thing.do() syntax" complaint on the Julia forums, and why telling them "semantically do(thing) does the same thing" doesn't seem to work.)

> none of the magic 'dunder' methods

Ruby do have equivalents to Python magic methods... disguised as normal methods. For example Python `__hash__` is Ruby `hash` and both are used by built-in dict/hash values and you should be aware of that fact in both. There are some philosophical differences as well, Python likes to have standalone functions that are customized via magic methods (e.g. `str` vs. `__str__`, you don't normally call the latter) and in Ruby everything is method (e.g. `to_s`). It really seems like a matter of taste.
I tend to focus on two types of value: entertainment stuff and actually-useful-for-my-job stuff.

A lot of what I read here on HN is the former. I'll probably never write my own compiler, but for some reason I can't resist reading an article that goes into gross detail about a 3% speed up in the Rust compiler. I don't sweat retaining the info I read. At best it's stuff to discuss around the lunch table with colleagues.

Then there are things that are truly useful for what I'm working on day to day. However, like with the pure entertainment stuff, I don't sweat about retaining everything I've read and putting it to good use. The reason is that there's a simple rule I try to follow - things that are important keep bubbling up. If we've got a problem and we need to fix something, then I'll dive extremely deep into reading about the problem we've got, and I'll put the stuff I read into practice _immediately_. By doing so I'll learn a lot and retain a lot. If I read an article that I think is interesting and could be useful _someday_ I might file a github issue to remind me to follow up, but usually not. Usually it's fine to let it go and dig in if and when there's a real problem.
These kinds of policy always scare me because people don't realize how prevalent politics are in our daily lives, even as devs.

Imagine that "booklet" is the same as the ADs you see when you browse the internet. And they are the equivalent of " You are the XXX visitor and Won this."

Family story:

My Gran Grandfather was from Trento Region in Italy (North), very poor.
At these times, there were some organizations working with migrants. (take note)

So he went to migrate from famine and poor.

Once on this organization, they asked him his scholar level, and he was like 3rd grade.
Not good enough for the US was sent to Brazil. (note 2)
He paid his fees, jump on a shit boat, and three months later, he was in Brazil.

Then arriving, the support he paid for previously was non-existent; all good land was already taken by the Germans, so they only one left were in the rocky mountains were because of the rocks that were very hard to work on the fields (note 3).

What I mean is: what looks easy today was so hard as yesterday.

And please people long ago were not better from today. I do think they were worse.

Note 1: These organizations at that time earned a lot of money with "fees."

Note 2: The people from the south with a more relaxed moral usually lied about this and were sent to the US.

Note 3: It was later known for good wine and tourist places. (grapes love rocky soil and can grow there).
This is just a solution looking for problems.

Unless it can help making my dream come true - of being able to open up my workspace (basically all apps in my laptop/desktop - IDE/browser/VLC/File Explorer.. basically my entire laptop OS UI) in thin air anywhere (as AR with glasses/goggles or projected hologram screens a la Iron Man) and allow me to work with a small trackpad and keyboard, it's just another toy innovation.

Why can't the Iron Man type interface be a reality by now? Meta AR seemed to have a grip on it, not sure if they've made an affordable commercial version that can support OSs out of the box - Ubuntu/Windows etc so that users can continue work in their workspaces right after putting the glasses on.

Basically I want to be able to code or watch youtube anywhere, in any comfortable position - lying down or on toilet seat or in a car.
