> As well, did you know lights have a flicker? If you think it's bad, it's even worse for dogs which can lead to stress.

As someone who notices and gets really tired from the stroboscopic effects of cheap LEDs, I can only imagine how terrible that must be for dogs
How is that different from transferring money through a bank?

I can understand the benefit of this from the standpoint that it will be essentially a global currency, which will reduce transfer times and just generally make it easier to send money, however I don't understand why a blockchain is involved. We already have similar solutions (Paypal, Transferwise etc), is blockchain just a way to market this thing?
Reminds me of my first job out of uni, 18 years ago. I was working on the SPARK toolset, and one of our customers was the Eurofighter, who still used VAX VMS for their development.

We had to maintain an old Micro VAX box in the office to periodically test that the toolset still worked on it. I seem to remember that the massive regression test suite that would run in a few hours every night on a PC would take days on this box.

Our main worry was that one day we'd turn it on and the drive would fail to spin up. I seem to remember there being a periodic reminder to just turn the damn thing on and let it boot every so often, then shut it down, just to make sure the drive was still ok.
In other news: China is using social media to silence dissent.

Corruption reports are of course labeled as fake news and erased.
Exactly. If this was a story about solar or wind it would be about how electricity generation does not include transport! We need to do lots of things all at once.
Because it's one of the very few cases where class inheritance is an elegant solution.
Unless you're playing it on a 75MHz Pentium, I think those people are right.
You can buy monitors made for commercial usage, such as signage. They'll be simple monitors with no TV tuner or "smart" functionality, and they'll be built to better resist burn-in.

They'll also cost you at least 2-3 times as much as an equivalent consumer TV.
That's interesting. My assumption was that they were using individual examples to show the aggregate effect of large numbers of people making such choices, at a scale great enough to influence flight planning, but in a way that seems relevant to us as individuals. After all, there are hundreds of millions of people in Europe. If 1% of them make a small but material change in their travel habits that's millions of people taking fewer flights, which clearly could have a material effect on flight schedules. It would never have occurred to me that, in fact, they literally meant us to think that one person making that choice would individually have that effect.
Digital payment is now almost ubiquitous in India also.
But, I still always carry cash with me, because of sketchy data network in crowded areas(including my workplace).
All digital payment system in India requires data connection on payer phone.
If they succeed in getting mass adoption for this thing, I feel like the companies on-board have basically bootstrapped themselves to sovereignty. It'll be interesting to see how that plays out, if nothing else!
In other news that we desperately miss, Sweden has developed a turbojet engine that runs on an ethanol-rapeseed blend. The completely green fuel is farmed on reclaimed land in Sahara, using a pesticide free automated farm based on solar robotic tractors. The necessary water is produced from sea water and clean energy.

Somehow, these are the kind of headlines my younger self would have expected in response to a global crisis. When did we all agreed energy poverty is the solution to our environmental problems?

Edit to prevent confusion: these, of course, are not real developments. It's the alternative reality we have the technological means to create.
Banks transfers take longer, banks transfers cost money and international banks transfers outside of SEPA network are a nightmare and they can get blocked/stalled for odd reasons.

Blockhain is a technical convenience - the Libra Association consists of 28 members. Everybody is more comfortable with money being stored on the public ledger rather than on a database server owned by Facebook. Blockchain is useful in cases where a collaborative/adversarial relationship exists between multiple parties. In this case this is regulators, governments, Libra association members and users. Blockchain keeps everybody honest, compliant and ensures data integrity.

It also removes some of legal responsibility from Facebook because they don't actually process the transactions themselves, it's peer 2 peer.
I like Go a lot. I just wish there was as much support in Go for machine learning as there is in Python.

At the moment, I feel like the whole "Python is the second best language for every problem" makes it the default choice for a lot of people.
Yes, this all sounds like a complicated way to say "obviously we've got to reduce air travel, but I'm not going to fly less, because what can one person do".

This should be a named fallacy.

Works in all sorts of situations: "obviously I have to eat less, but not this mealtime".
I'm not holding any coins. But I have an interest in crypto currencies for some projects I'm developing.

Anyone who thinks this is going to replace ripple, I have some bad news for you.

Ripples main focus is not for users purchasing goods across websites. Its focus is mainly for banks (to hold vast amounts of XRP) when sending sums of money to each other, to be able to convert fiat into XRP and then send that XRP between them and then convert XRP into the receiving fiat currency.

The remittence market is huge and that's where ripple is mainly interested. Both banks and businesses are using it because there is a high trust factor with Ripple.

Now of course Facebook is trying to supplant ripple here, as a user won't need to go to a bank or remittence provider which would use either SWIFT or XRP to send the funds. Instead facebook is hoping to tap into the network effect it has built and two users can send monies between each other using this new token.

Another thing that I have an issue with. The article mentions eliminating "rent seeking". How so? Paypal, Visa, Mastercard all charge a % when processing a transaction. The $10m buying fee needs to be recuperated. Are transactions going to be free? Perhaps... Is running the nodes and network going to be free? It's certainly not.

There is going to be a fee for sending currency across the network. Either an up-front transaction fee or a conversion to FIAT fee. But there will be a fee.

If the same old players are involved, you can bet they want to get paid and the same old players will want to eventually impose their own rules to the game.

Personally, I don't think this will usurp Bitcoin. If anything else, I think it will make people more comfortable with digital currencies and then we'll have more leaps in better tech and the free market will bear fruit of a much lower priced solution than libra coin.
No, this is HN. It's the same people as Reddit only being pretentious is somehow fine here because we're special?
In transport, we have learnt over the past century to not use aggregate models, as they do not provide the same detail and results as disaggregate models[p.18 Modelling Transport 4th Edition Ortuzar & Willumsen]. We should not lower our standards when discussing emissions and pollution.

This article above is a very worrying case - where the reader is encouraged to shame people for flying, without showing necessary statistics as to whether flying is indeed much worse than other transportation methods.
We believe that a global currency and financial infrastructure should be designed and governed as a public good

And social infrastructure?
Cryptocoins are not about privacy, the ledgers are public so no conflict there.
That would mean they are an intermediary in the blockchain.

I suspect the requirements of the whisky industry for peat are probably pretty tiny - as far as I know its only the smaller higher end distillers that actually burn peat.
I live in the north (Norrbotten) in a smaller community. There is a point to take the train between Gothenburg and Stockholm instead of flying for example, but taking the train from Luleå to the south is simply not worth it. It's just as expensive (sometimes more so) and the trip will take at least 15h longer...
>But the airline industry is fighting back with a promise that a new generation of planes will halve emissions by 2050.

These timelines are a bit of a problem.
You'll need to annotate or remove a lot more than Theranos if you're worried about truth or ethics
What's the use case for it? It looks like the point is to send money from people to people easily. But how about businesses? Currently I can pay with Contactless in shops, and on online services, paying by debit/credit card is straightforward. So I'm not seeing exactly what it will be used for.
On being a currency, since its price fluctuates too much to be taken seriously, so it's used as an investment instead.
ATT and Verizon (and T-Mobile and Sprint) own all the mobile communications infrastructure. ATT and Verizon own a lot of the wired communications infrastructure. They are not going anywhere.
The day I consider my WWW browser the most important software on my PC is the day I go back to dialup. Frankly, I agree with your base theory - that's why the important software on my PC is Windows and MSOffice, rather than *nix and Open or Libre Office. I moved off the OO/LO platform a little after the split, because compatibility was an issue.

But for a limited use program like a browser, yeah, I want the people who won't disappoint me.
Congratulations to Facebook for releasing code. I’m excited to see how the industry evolves.

We look forward to showing the world what we’ve been working on at MobileCoin when it’s ready.

Privacy matters.
What's more, I remember reading about "vliegschaamte" in a Dutch newspaper recently so the word has arrived here too.

Sounds by that story that the other orders were intended for the other people eating given that the peanut free order was explicitly made. So I can only assume the waiter assumed the rest was an order for the others? Maybe that assumption may not (legally) be made and a warning needs to be made for everyone at a whole table? Either way that seems like a bit of a gray zone. Sounds almost like the point was to trip up the waiter.
In transportation, cargo ships. It's claimed the 15 largest cargo ships pollute more than 50 million cars combined. But for CO2 it's apparently still a single digit contribution. Lots of individual sources are adding up to the global total.
Stockholm and Göteborg are not a good example (or the opposite..) since they are too close to each other, ~500km, to cancel the wasted time going to and from the airport and waiting to board the plane.
The fast trains from those city centers are indeed better than flying, although the price compared to low cost flights is too high.
I don't totally agree with your conclusion- I would take trains from Stockholm to central Europe even with kids but only if prices were significantly better than low cost flights, I don't mind a 24 hour ride to Berlin with a stop over or two, but the price is actually higher than most low cost flights e.g. Norwegian
I can't believe the amount of "you are a horrible human being for working at Facebook" comments I keep seeing as soon as someone says they are working there.

HN is great because you normally get comments straight from the source, but I'm worried we will inevitably shame Facebook employees into not posting here at all.

The whole flight does not need to be cancelled. Underselling flights are often replaced with smaller aircraft. One person might not make a difference, but if 10 or 20 cancel, an A321 may get replaced by A320 or A319, which are lighter and burn less fuel.
Let me guess:

"We try to stay away from such pesky questions but are convinced that the amount of good that Facebook can do is unlimited"

Yeaah.
I think it's a reference to the Roman libra, which used to be both a monetary and weight measure.

This was actually one of the many selling points to get one of these. No regrets so far.

I went to a music festival last weekend. All of the vendors had machines for taking card payments, and none of them worked because there was no phone signal.

Of course, I had a pocket full of cash, so didn't care, but a lot of people didn't.

A fair financial system is one which I am comfortable giving to my worst enemy to run.

This is not it.
Conception. It’s pitched as a replacement for government backed, fiat currency. But I’ve never heard or seen a convincing, coherent explanation that makes it clear this is a currency. For one, a currency can’t be reliant on an internet connection for validity. My 1$ bill in my wallet absolutely does not rely on that. In fact, there’s an entire country validating that dollars usefulness. A gold coin essentially answers the usual doubts in fiat currency.
I must say I haven't even played a traditional rogue-like and it might derail my plan as well...

I would consider moving to Sweden or another country that caters for people who, out of choice, prefer quality public transport with things like overnight sleeper trains.

I don't fly or drive. Haven't done so this millennia. Therefore I only think in terms of trains, bicycles, the bus and walking. In my made up mind cars and planes are dangerous and cramped. Plus you have delays at airports so it is actually better to just get the train, avoiding a taxi ride the the airport and a huge delay just to sit in a cramped seat.

In a culture where everyone flies or drives it is hard to do trains and bicycles. I think that if the decent trains are provided and the service is better then there will be more people who just prefer the train. Same with cycling infrastructure.

Inherently trains and bicycles as well as the bus can be a much more pleasant option. But when you have a ruling class shuttered away in tin boxes for their transport needs with them being at the beck and call of aviation/auto lobby people then things get skewed at the planning level.
A passenger jet burns 10-15 liters of fuel pr km. Stockholm-Geneva is about 1600 km, so 3200 km round trip. So the numbers seem at least to be in the right ball park.

Here's a bunch of physics if you're into that sort of thing: https://therocketscienceblog.wordpress.com/2016/08/01/how-mu...
Since he said "flyskam" and not "flygskam" I'm guessing this is a Norwegian person. Yes in Swedish it's processorkraft or beräkningskrfat.
This isn’t true and injecting grievance politics into an unrelated conversation is not going to result in anything positive.
That's interesting. We switched to LED bulbs in our living room and after that our eldest dog would not settle, I thought maybe the bulbs had a low humming noise he didn't like but it could have been a flicker instead. We switched back and he was fine again.
Good point, but once again - the crossing of thresholds is the major change, rather than the individual changes between thresholds.
I just don't think Go has a place in new code. I know Googlers (who shall remain unnamed to protect the innocent, and politics at that company can kill your career) who joined the Go fandom because its their company's language, their department was C++ or Google-flavored Java heavy (arguably, a Java style worse than 'normal' Java or Android's dialect), and it was their only way out...

However, when they were exposed to Rust, a lot of them converted to Rust, and now write Rust for Google on internal apps that need performance but safety, especially during concurrency. Others were exposed to Kotlin (especially due to the Android guys), and are championing that as a replacement for Google-flavored Java inside the company, since the JVM is also very sane when it comes to large scale safety during concurrency.

So yeah, if I was writing brand new highly concurrent coroutines-like code, I'd skip Go and Goroutines, and go straight to Kotlin and Akka (not written in Kotlin, but very natural to use with Kotlin), since I end up with the power of the JVM, the elegance of Kotlin's syntax, and the Erlang Actors brought by Akka.

And for those who have never used Erlang, learn it once, write something highly concurrent in it, and you'll learn to distaste almost every other language's faulty concurrency idioms almost immediately. Without the Erlang actors model, you're not going to be writing fault tolerant concurrent systems; just like "all languages converge until they become LISP", all concurrency systems converge until they become an Erlang actor model.
As someone somewhat out of the crypto-loop, would someone be able to explain/posit/cite why Facebook are entering this market, and why traditional payment providers are also getting involved? On the face of it, this suggests it aims to essentially reduce transaction costs (which would be to the detriment of the status-quo)?
"Tried to do the same in a tourist city (not a tier 1 city), beginning of May, didn't work."

I'm curious - did you go to an official China Unicom store (i.e. owned and operated by China Unicom) or an independent retailer that happens to sell SIM cards?

"I wanted a full SIM, not a data only SIM though, which one did you get?"

A regular SIM with a voice+data plan.
Simple explanation for the "Why" is that caring about something takes mental resources, and our consumerist free market is optimized towards extracting all our available mental cycles and put them either to produce or to consume, for the benefit of the companies that make up the economy.

Life is easier if you just follow the script and go along. Any remaining resources for "caring" about your life and your best interests must be detracted from the race to make a living, and not everyone is in a financial position to afford that luxury. Quite a departure from the vision of the founding fathers who designed our political system, who were people in a position to care for such things.
Using less energy is one solution not the only one, but probably the fastest to apply.
And I would love a link too, because this sounds too good to be true.
Not all whisky is peated. At the current rates, there is enough peat for hundreds of years of whisky production, even if no new peat was formed, and it regrows at around 1mm/year, which is quite sustainable, if we stop using it for power generation.

All of the makers of peated whisky are committed to protecting the peat, as far as I know. And their peat usage is absolutely miniscule compared to its current use in power generation.

Bruichladdich has a good summary: https://www.bruichladdich.com/faq/is-peat-sustainable/
It is sad that Zuckerberg chose to squander all that capital on frivolous endeavors at Facebook. He could have done so much.

This is what gets me the most: "We believe that a global currency and financial infrastructure should be designed and governed as a public good." It's very rich coming from Facebook who could have made itself a public good a decade ago.
They are aware that a shift in the car market is happening. Therefore they can legislate that this thing that is already happening must happen and claim credit when it does.
Finally! Someone besides me here who would recommend Dashlane. For some reason, it is always missing from these threads on HN.

Been a user for 3-4 years now, and would definitely recommend it.
What "Flygskam"? Do you consume a lot of traditional news (TV news, newspapers, Public service radio)? You couldn't have missed it.
Don't use Facebook's cryptocurrency.
Good question. I think it will get plenty of hate, but most countries don't have the level of Facebook hate that the USA/Europe has, and lots of people don't particularly care about the crusade against Facebook. It would probably get a lot less hate if they weren't involved, but here we are? NYTimes takedown coming in hot!
EVs use their brakes less because of regenerative breaking. The particulate matter of tires is for the most part comparatively big an heavy, so a larger part of it stays near the ground and gets swept away by rain, and could be cleared in problematic locations by wetting the street (also bigger particles seem somewhat less problematic for health).

You're right that EVs don't fully solve the problem, but they are a giant step in the right direction.
I believe peat use is rare in the malting for Irish Whiskey. More common in Scotland but still not the majority.

But presumably you could burn other fuel and get a similar result. The traditionalists would be grumpy though.
Peated whisky is a specialty product, with rather small production scales compared to unpeated Highland and Speyside malts. So yes, it is quite sustainable, given the regrowth rate.
Isn't it still the model that is exposed to the programmer, even though internally all kinds of things are going on to make it all go faster? For example, nowadays many/most processors have separate caches for instructions and data, meaning that they strictly speaking don't conform to the Von Neumann architecture. But the programmer doesn't see the different caches, ideally doesn't even see the cache at all.

It's like the execution model, where processors do a lot of out-of-order execution, but do a lot of work so they can present a model to the programmer as if everything happens in-order.
More data mining?
They create a new transaction from their probably inexhaustible wallet to your wallet.

I don't know much about Calibra, is it a public blockchain? Can anyone build a client to generate transactions and mine blocks?
If the blockchain is public, the transactions themselves are public, so can't really be sold. The association between user data and transactions, might be valuable though.
"Its focus is mainly for banks (to hold vast amounts of XRP) when sending sums of money to each other, to be able to convert fiat into XRP and then send that XRP between them and then convert XRP into the receiving fiat currency.”
With the exception of Ripple money transfer products working without XRP, which they don’t like to shout about.
There are cryptocoins like zcash where the ledger isn't open in the same sense it is on Bitcoin or Libra.
There is a difference between decision making and calculations of change.

I am certainly not arguing that decisions shouldn't be made responsibly. I am merely trying to point out that the calculations that have been made are simplistic.
I just skimmed through their documents and I saw they use BFT. BFT algorithms are slow (and slower when more nodes are added) so are they using another layer for gaining performance?

Currently the fastest BFT implementation is BFT-SMaRt: https://github.com/bft-smart/library

This is some seriously ridiculous mental gymnastics (continuum fallacy). Someone who never flies is now responsible for the environmental impact of those who fly, because specifically their lack of flying is not canceling any flights (or preventing any flights from happening)?
262 might be a high estimate. At 750 gallons/hour[0] and 9.57 kg CO2/gallon[1] that's about 18000kg for a 2.5 hour flight.
