> too volatile, too risky, too energy intensive

I am no expert but those three are features, not defects.

1/
Until there will be a central authority linking cryptocurrencies to the old financial system - impose taxes in CC - it will be volatile.

2/
Computer security is not something that can be definitely solved.

3/
Proof of work is the core concept of the blockchain. Maybe there will be some other CC technology in the future not based on blockchain that will not require proof of work, but that is outside of this discourse.
They organisers knew the courts had instructed police to stop it.

If they wanted to protest then they should've organised protests and demonstrations, which are perfectly allowed in Spain. That would be the democratic way. Not to insist on breaking the law and disobeying court orders.
commandeer
v.
To force into military service.
v.
To seize for military use; confiscate.
v.
To take arbitrarily or by force. See Synonyms at appropriate.

The response in China was relative to how important naming a child is in Chinese (really, East Asian) culture.

You are applying western standards to the Chinese response, which makes little sense.

This is why I switch my wifi radio off every time I leave home. Especially when going to travel via the tubes.

And this is why the "50-shades of wifi off" of ios 11 is so idiotic.

Don't have iOS 11 yet so don't actually know how many steps I need to take.

Oh I was on desktop. Maybe my monitor's resolution was too low :/
That is ridiculous.

There was a court order to stop that action.

What sort of democracy is it when you can just ignore court orders?

If they wanted to protest then they should've organised protests and demonstrations. If they really wanted to make a point, organise a symbolic voting and have someone face the charges.

To go ahead with the whole thing was reckless. The courts cannot afford to allow themselves to be ignored.

That's the very opposite of the rule of Law!

The problem with useful proof of work, is that the emission rate becomes very hard to control. In most PoW consensus algorithms, a difficulty parameter is constantly updated to keep the average block-time around 10 minutes. To do useful PoW consensus, you'd need to find a useful problem, where the difficulty of solving the different problems is easily solved, while the solution to the next block, is still dependent on the solution from the last block.

Imagine you need to need to transport water to your home. You start by consulting best practices and blogs and conclude that the only way to take water somewhere is using a helitanker. This is a dual rotor helicopter with an enormous hold. You consult a building planner to construct a helipad on your roof. You seek an expert helicopter pilot. You spend several weeks poring over different models of helicopter.

You can do a lot of iteration and eventually reach the right result, but that still won't stop your house burning down in this analogy.
I'm not nervous about that though. I simply lack self-confidence. As soon as I make eye-contact with a girl I look away.

One thing I wonder when looking at chocolate "how it's made" documentaries is just how much extremely cheap space and labor is needed to produce cacao.
As far as I know, the iPhone only randomizes its MAC address after the device has been locked for two minutes and not connected to any known networks. Two things that are very unlikely to happen in a subway. One of the advantages of riding the subway is that you can use a phone and the other one is that there is rarely any cell connection (at least in my subway), so you need WiFi anyways.

WiFi randomization is great if you are going to the store by car because the devices on the way there cannot track you but once you arrive there, check your texts it is game over.

It's notable that there's quite a few places in busy stations where the most direct route between two lines (or from one line to an exit, etc.) isn't signposted, because the footfall between them exceeds the capacity of the (typically older) direct tunnel.

Indeed, "real-time" is one of the most requested features for S3stat, even though there's really not much you'd be able to do with faster data. In our case, Amazon doesn't even deliver their logfiles until 8 hours or so after the fact, so "real-time" reports would just be a pretty moving picture of the past.

I toy around with the idea of building it out as a feature anyway, just so that I can charge a premium to customers who want to turn it on.

Isn't this a case with any niche terms? For instance I've had the same issue with names of various kitchen tools and utensils - you know their name in your mother tongue, and when you need it you usually get away with: "give me, err, that thing", so you never pick up the proper name in English...
One question : the deflationary nature of cryptocurrencies means that early adopters are rewarded disproportionately. Is this a bug or a feature? It seems unfair for the late adopters and is also one of the reasons people draw parallels to a ponzi scheme. I've not come across a good explanation for this, so any thoughts?
> Accuracy (how precise the data is). Everything should be accurate.

Accurate and precise are different things.

You can be precise: We averaged 1 sale per hour today +- 0.01

You can be accurate: We sold 8 things today

You can be precise but innaccurate: We averaged 100 sales per hour today +- 0.01

You can be imprecise and accurate: We sold 8 items today +- 10

And you can be both: We sold 8 items today +- 0.01

And you can be neither: We sold 100 items today +- 10

Yep. And the slippery slope argument is valid. Democracy is better served by strengthening voices of the people, rather than consolidating it in the hands corporate-governmemt elites in the name of fake news.
im generally talking intel c++ compilers, etc. When I was doing EDA, we used to fork out a lot of cash for these compilers and these guys used to work very closely with us to optimize for certain kinds of code styles - for example loop unrolling on HP-UX, etc. I dont know if this is still a thing, so i might be mistaken.
Absolutely! And even ‘proof of stake’ alternatives tend to degrade into ‘proof of work’ (citation required: unfortunately I’m on mobile and don’t have the link to the relevant papers to hand!)

Note: Even basic forms of proof of ‘useful’ work, like using the heat from the miners’ CPUs, just act like a subsidy and push the cost of competitive mining further away, rather than making the blockchain more efficient...
What atmosphere? I can look around right now and see 10+ male-female conversations happening with eye contact and no accusations of flirting, being a creep, etc.
My gut feeling says a set of open AI challenges, where the work is “train to solve this with accuracy > $difficultyParameter”, and the proof is something that both tests the accuracy of the work, and (if this idea is even possible) demonstrates that it wasn’t over-fitting/memorising.

Surely this would be an automatic sanction when GDPR comes into effect, leaving your wifi on isn't exactly "explicit consent".
Is it just me or do others out there also get angry when people refer to "crytocurrency" as "crypto"? I know perhaps in their circles it's a handy abbreviated word for "cryptocurrency", which admittedly is a mouthful, but this just makes me angry that they would conflate "crypto" (upon which the whole basis of the modern internet is built on), with a form of currency that people have no idea about and are just mindlessly speculating on. Perhaps it's because I've taken some classes on cryptography and understand how beautiful a subject it is, that I find it demeaning for people to use "crypto" to mean "cryptocurrency".

I live in Australia. My kids are well-versed in British and American animals like squirrels, badgers, hares, raccoons, moose, bears and deer from childrens books and songs.

However, we don't have any of them here in Australia.

Knowledge of animals and experience in nature are frequently unrelated. My kids spend plenty of time outside but how often do they see animals (other than the occasional bird)? They're asleep when possums and fruit bats are around. They occasionally see kangaroos on their grandparents farm. In general though, they see cats, dogs and other pets: the animals we deliberately introduce to kids.
The mail says:

We only use the time from the HTTPS header, and not the TLS timestamp, as the latter is most possibly randomized in modern SSL/TLS implementations.

I’m not sure I see the issue with iOS11. 3D Touch Settings and select WiFi and toggle it off. It’s about as much work as opening control center.

If you don’t have a 3D Touch phone you have to open Settings and Navigate to WiFi which is right at the top of the list with Bluetooth and Airplane Mode.
This seems a bit extreme but on the other hand Googles approach is completely worthless.

I would say, start the process while logged in to the account and then have the legal documents verified at an Apple Store.
They want to be able to charge advertisers more based on potential viewers of their advertisements - they probably charge a fixed fee / week for ads now, then they can go "Yeah according to our analytics a million people viewed this ad, vs 100K for the other, please pay more".
Why are you optimizing the LOC only for Java? With a little bit of tweaking, Python can do the whole thing in 2 lines -- no imports, libraries or closing braces needed:

with open('alice.txt') as inp, open('new_alice.txt', 'w') as out:
out.write('\n'.join([line.rstrip().replace('Alice', 'Dora the Explorer') for line in inp]))

The author's point is that Java is verbose and requires a lot of boilerplate, which has benefits and drawbacks. I think her example does a decent job of illustrating that.

That's what notaries are for: "Identifying the person appearing before the notary by reference to significant proofs of evidence including passport, driving license, birth certificate, diplomatic documents etc." [1] Notaries are licensed by their governments to perform this service, and can do so by inspecting the person's documentation and certifying that fact to a third party like Apple, without needing to share a facsimile of the actual documentation with the third party directly.

There aren't that many Apple Stores in the entire world. It would be a considerable burden to expect people to travel to one. Apple Stores are present in only 17 countries, and there aren't any at all in Africa, India, or South America. This Business Insider article has a map:

If you understand how people get from A-B (which lines, what paths within stations) you can better control overcrowding.
If I understand correctly, Feynman implies there exist other defining properties, better than names, that are preferable when thinking about animals (or objects in general)... unless one is communicating with other people, in which case a name will do.

But it's names all the way down! These substitute properties are also only names. Using articulate attention (science), we divide the world into abstract categories, giving names to classes of "things" that are in fact unique, even if the classes are fuzzy around the edges and just leaky abstractions of reality.

Is thinking in terms of the swirling, teeming, interconnected mass of "stuff" that's truly at the core of Nature a useful tool for getting ahead and making progress? It seems it's just too much to grasp, with everything unique and indivisible, no categories, no repeats. Even leaky abstractions (thrush! tiger! rock! water! human!) do better.

To question the utility of names is to question the utility of the power of articulate discrimination, one of evolution's critical inventions. Not sure what lies that way except inarticulate madness.
>Jeffrey C. Hall, Michael Rosbash and Michael W. Young were awarded the Nobel Prize in Physiology or Medicine on Monday for their discoveries of molecular mechanisms controlling the circadian rhythm.

The three United States-born scientists used fruit flies to isolate a gene that controls the rhythm of a living organism’s daily life. Mr. Hall, Mr. Rosbash and Mr. Young were “able to peek inside our biological clock,” helping make discoveries that “explain how plants, animals and humans adapt their biological rhythm so that it is synchronized with the Earth’s revolutions,” the Nobel prize committee said.

By examining the internal workings of fruit flies, the three helped determine that the gene they were analyzing encoded a protein that accumulated in a cell at night, and then degraded during the day.
You just gave me the first real use for 3D Touch since I got my 6S. Thanks!

On the subject, one swipe + one press using control center is really much faster than finding the settings app. For me it takes at least six actions to get to the switch: press home twice, open a folder, scroll, open settings, click wifi). Even if you keep settings in your home screen that's at least four clicks/touches away.
It's what news orgs have been doing for a long time. The number of people addicted to this crap is much more than the number of people who can do something useful with it.

Why that is, has more to do with psychology and evolution of the mind than it has to do with the actual real time data or news.

The last LR version I used was LR3 and performance was really not a problem. That was 2010, mind you. On an even then outdated dual-core AMD system with the images and the catalogue on some old hard disk.

So, am I correct to understand that Adobe managed to botch LR so badly that PCs with vastly superior processing and IO to what I used back then struggle on basic tasks?

Woah.

Agree they should have not use a bespoke algorithm but I don't think there is much of a security issue. Knowing where you need to go to vote is not enough to vote.

You still need the physical security of the ID (DNI) that includes a few security features (like your face). You can see and image here: http://www.aulaclic.es/articulos/graficos/DNIe.gif

From my point of view, this rises a far more interesting question.

Do you guys think it could be possible to use blockchain to implement a secure voting system? I do and I got a few ideas about the main issues (authentication, authorisation, validity period and others) and will be happy to discuss with anyone interested on co-developing such a system... or if you know of one already do let me know!

Seems like if every computer can be a "poling station", authoritarian regimes/governments will have a more difficult way of stopping this sort of voting from happening. And maybe, only maybe, we can enjoy a free democracy.
If this sounded like a bad idea to you, and you wondered what new tech made this possible - there is no new tech mentioned and you can safely skip the article.

It’s basically just a list of reasons why this does not work at all.
I was surprised to learn Postgres doesn't use direct read/write (O_DIRECT) to bypass kernel caches.

The article doesn't go into the details, but maybe someone can point me to some resources that explain the benefits of this double cache layer?

All I can think of is PHK (author of Varnish) arguing for exactly the opposite: use only kernel caches with clever mmap.
I think the deflationary nature only reflects the ideological beliefs of the creators. Inflation is a type of tax, therefore for a currency to be a "true" store of value it cannot be deflationary. If extra crypocurrency can be printed, who decides when the monetary base gets expanded and by how much? That's not an easy question to answer in a distributed system. So you end up with a fixed monetary base (and therefore deflation).
