Comparing CC prices against Bitcoin prices is also a bit apples of oranges - the CC fees are larger but CC users are getting a significantly "larger" service as well. A BTC transaction is just the initial money transfer, but a CC transaction is a package of money transfer + fraud insurance + some money-back for the payer; if you'd want to compare prices then you'd need to look at something like BTC transaction + an escrow service fee.

Just technically executing the transaction is a minority of the problem and a minority of the cost; if you'd do BTC transactions with a proper consumer protection service then that part would be far more costly than just the transaction.
As a person living in mosquito-prone area, I would say that those concerns are secondary to the quality of life implications even before diseases are taken into account.

Those mosquitoes had it coming for a long, long time.

But I have only now thought out of a different reason. Basically we had the choice of either living with malaria mosquitoes or converting all of wetland into dry land, completely destroying ecosystem that was there. But now we have option of just eliminating mosquitoes while leaving the rest of wetland intact. To me it does sound like a plan.
Supposedly ecologists who have researched this believe that there are other substitute insects (gnats, flies, etc) that will provide enough food that removing mosquitoes would not be catastrophic.

I'm a little dubious myself, but I do hate mosquito bites, and I don't even live in a malaria zone.
Out of curiosity, you couldn’t just guess them based on knowing a couple? Or do people assigning them in some fashion that isn’t consecutive within the block?
I don't think they were denigrating farm workers nor pushing the hipster aesthetic. It was a problem with not following Apple's own guidelines and making something that clashed so much with the rest of the system.

Depending on what you're doing, this can make a HUGE difference.
That's a good point.

In programming, there's the idea that "The code shouldn't merely work, it should clearly work". If your configuration system becomes so complex that the same principle applies there, that's a bad sign.
Durability is a student's research project at the moment. It's up and running for "Spark" style computations but the work has broader ambitions. In essence, all of the internal state in DD are easily (automatically) serialized LSM slabs, and it is cake to write them out and read them back (and almost cake to make sense of them).

https://eurosys2017.github.io/assets/data/posters/poster21-Lattuada.pdf

Which Kafka link is dead? The work has quiesced because any next step seems to be involve assuming something about timestamps in the input. At the same time, it seems to take about 10 lines of code to write a Kafka source or sink, minus any careful worrying about acks for durability.

The DD and Adapton approaches may be a bit tricky to hybridize. Much incremental compute works by moving through a sequence of valid configurations, and DD's main departure is generalizing this to partial orders. So, maybe you could borrow ideas, but it would probably be original research to do so.

Then go ahead and fork your block size to 50kB. You're autonomous and you have the volition to choose the software you wish to interact with the economy you wish to participate in, and you just clearly and repeatedly said smaller blocks are better, so hard fork away from the temporarily imposed limit that Satoshi clearly said could be removed at a block height 400k+ blocks ago, because it was never a temporary limit at all, according to you, it's an individual limit that you're free to choose to set to whatever you believe it ought to be.

But of course, that's a lie, such a change would not be liquid with the rest of the economy, and you'd have forked yourself off into irrelevance, just as the fools who tried to set the 1mb temporary limit to permanent have done themselves. That they're too stupid to figure out they're on the wrong side is of zero consequence to the fact that they are.

I am mainly using italian company Tophost to register my domains, and domains usually cost cost 5.99€+ vat. And they're still making profit from that. So I kinda call bs on this "no added fees".

OTOH, I have to say that Tophost is not the prettiest or the coolest, but so far I had no real issue and the price is low.

However, it's nice to see another player joining the game.

Regarding the $0.99 domain... Didn't it sound alarming that you pay a domain so little?

You can't really compute it in constant time since the number of bits in the nth Fibonacci number is O(n), so you need to take at least that long just to write the result out.

Computing with Binet's formula is also rather tricky. You just need to round φ^n/√5, but how many bits of √5 do you need to use?
I write kernel mode drivers as my day job, and this is certainly the first time I've ever heard of non-swappable being called "wired".

For what OS? Consider https://wiki.freebsd.org/Memory

Wired

- Non-pageable memory: cannot be freed until explicitly released by the owner
- Userland memory can be wired by mlock(2) (subject to system and per-user limits)
- Kernel memory allocators return wired memory
- Contents of the ARC and the buffer cache are wired
- Some memory is permanently wired and is never freed (e.g., the kernel file itself)

OSX is derived from BSD.
I assume we'll see it being more used by Apple at the system level a year or two after they got the ABI stable. Somewhere around iOS 14 or 15 maybe.
It can be a gateway for learning interesting things about the mechanics of a language, its compilation, and in turn how to make similar cases in other languages faster/cleaner/more-secure. e.g. why is nim so fast in this case? Is it tail call optimisation, not doing overflow checks, static inlining, or something else? Nim compiles to c to it is especially odd.

Check my other reply above. Did some FreeBSD work ~15 years ago, but I guess I'd already forgotten.

It's not that there's no connectivity. Whatever they're using for metadata is extremely slow. As though all requests need to go to California or something.

Yes. This is how Linux package managers all work; metadata is cached locally so search (and dependency analysis - not needed in AppStore) performs well.

I did a transaction yesterday. It cost around $0.08 and was confirmed in 15 minutes. However, given how very unlikely it is to reverse a transaction (you'll need to double spend, not an easy trick to pull when you are paying for coffee), the guy just acknowledged the transaction.

So yes: It is cheaper.

Speed? Yes, it is faster. If you send me money through PayPal or another gateway and I don't trust that one. I'll need to withdraw that money to my bank account. That's another few days. So bitcoin is faster is that it gives you your money (cash). A credit card ATM withdrawal can also be just as fast.

woah woah.. America just left the Paris accords. China is still committed to them.

> As to "8 million tons of plastic garbage going into the oceans every year[1], a depleted Ozone layer, black lung, asbestos, and unbreathable air. " America does rather well at getting rid of those, China is the biggest offender.

America is terrible at getting rid of those. See: https://en.wikipedia.org/wiki/List_of_countries_by_greenhous...
USA is number 2 on that list. And worse, it's government is living in denial, with a president that's refuting climate change as a problem (and as mentioned earlier, has withdrawn the US as a signatory to the Paris agreement).

And this tells just part of the story. See: https://en.wikipedia.org/wiki/List_of_countries_by_carbon_di...
That's the list of countries by CO2 emissions on a per capita basis. Among the large economies of the world, the US is the first on that list and also way, way, way, ahead of China.

Again, this is just part of the story. We can't ignore historical figures for greenhouse gas emissions. China has only recently (since after the 1960s) become industrialized. It became a significant contributor to CO2 emissions only after about 1980, and even then it was way behind other countries. (way behind the US too). It's only recently, since about 2010, that China has overtaken USA as the largest emitter of CO2 and other green house gases. Even then, on a per capita basis, it's way behind the USA.

And you say "America does rather well at getting rid of those, China is the biggest offender." That statement is so factually incorrect it verges on being ludicrous.

Get your facts straight, and then when it comes time for another election, vote for the senator, congressman or president that considers climate change a serious issue and has an agenda of fixing the US contributions to CO2 and other green house gas emissions.

In New Zealand, EFTPOS costs the retailer a fraction of what credit card transactions do. When you swipe/insert your debit card, it goes through the EFTPOS system. But when you use the same card contactlessly, payment is processed by the credit card company and the retailer is charged a credit card fee or similar. That's the reason many retailers don't accept contactless payment.

The banks and card companies would surely love for EFTPOS to die, but the retailers love it. There's a reason every card issued today supports contactless payment, and you can't opt out.

People come out with all kinds of wired solutions to the facebook problem. But the most important question to ask is not whether the new solution solves facebook problems. More importantly, you need to ask is there a demand of the new solution. 99.99% of the time, the answer is no. Why would anyone pay to post message when they can post for free in other social networks. It will never go mainstream unless there is a real demand and little friction.

BLE-Backscatter: Ultralow-Power IoT Nodes
It was 1999.
I hate doing this kind of comment, but given the unending stream of "this battery solves everything" articles, so does this article provide actual numbers, compared to batteries in production, or development batteries at similar levels of development?

Or more specifically, what are the answers to these questions:

1. What is the charge/discharge efficiency? This seems to be something lots of the "next generation batteries" in articles are bad at (compared to current commercial batteries)

2. What is the cycle lifetime?

3. What is the power density?

For 2 and 3 there was an article on HN last week I think that was using a gravity potential "battery" that was carbon neutral (and based on super simple physics) simply by using an electric motor to lift weight, and then discharge by doing the reverse.

[edit: Using the power of wikipedia it seems like power density is high, but it also says they're not rechargeable. But also that they are. So can someone who actually knows the chemistry of batteries give a summary?]

Wait.. hold on for a second.. and think about the following points.

1. Campaigns cost a lot of money.

2. Private organizations fund political campaigns.

3. A legislator's constitutional job is to maintain an effective set of rules for a country/state/city whatever.

4. Is the democratic process effective in voting in the best legislators?

4.a. or is the democratic process the best at voting in the best fund raisers?

5. With the massive amounts of private capital, are the best innovators, engineers and builders succeeding or are the best fund raisers succeeding?

6. Is private capital largely responsible for the success of new companies (ventures) as well as aspiring legislators?

Well, not everything is so black and white as those points, but looking at one extreme perspective, does raise many concerns in my mind. The primary one being, "is democracy reaching it's breaking point?"

It may be in decline, but like a ship slowing down from light speed, it will take years before there's any significant change in the social media landscape. They have a very long time-frame of opportunity to turn their ship around, and it wouldn't surprise me if they do.
