>The video was of the man receiving the item he ordered 5 minutes after he ordered it! It was around midnight not sure of the day but 5 minutes to his door step from ordering it!

Feels like a viral marketing stunt to me. There's zero reason why anyone would want a phone within 5 minutes (or even same day). In the off chance that they do, they could simply walk into a physical store and buy it there. There's no need to set up a real time delivery network for that one guy who needs a phone delivered the same day and can't walk into a store.

>I asked my friend how is that possible so he showed me an image of a map of Xiaomi warehouses. I can't recall if he said there were dozens or hundreds per city.

I have a feeling they're closer to "stores" than warehouses.

There is one issue with Uighur people in your statement that if you dig into history, Han Chinese have been living in Xinjiang much longer than the Uighurs. In fact, Chinese people have been in Xinjiang even before the Han dynasty, and incorporated some Buddhism-worshiping minority groups and formed the so-called Han Chinese. You can still see the splendid ancient Buddhism relics in Xinjiang. Uighurs, a Muslim minority, entered the region several centuries later, mainly after the Yuan dyansty. To compare with, there is another Muslim minority, Hui, descending from the Central Asia and Middle East (Persian) immigrants during Tang Dynasty. So if people argue that “ancestral land”, they really need to see that in good ol’ Asia, history is such a bitch that one can easily get lost. But that thousands of years old bitch still haunts you in the night.

The trade war with Japan started in the mid 80ies and finished by the mid 90ies. The quality of life in Japan (as well as their GDP per capita) didn't improve since then. However, the quality of life in Japan was pretty good even before the 80ies.
One other thing is that httpie is typically an interactive tool. If I were hitting services in a loop I’d just write a Python/requests script to do it rather than bash+httpie.
The name is reminiscent of an advent calendar, which traditionally has a labeled door behind which is a piece of candy, small toy or other trinket. These calendars are intended for young children to remind them of the period of advent.

If you are religious, look upon this as a similar thing which reminds you of the season, building in anticipation of the final day.

If you are not religious, it's just a word with no special meaning other than the time of year. Same goes if you are not of a Christian religion.
And you are going to connect those two networks precisely how?

The point in the article is that WA's grid is isolated from the Eastern States' grid. If there was any hope of "following the sun" (or indeed the wind) to leverage the geographic diversity that is Oz' one true strength, those networks would need to be interconnected.
The problem with “managing” a commons is the principal-agent problem — that the people you appoint to do the management will often wind up making or interpreting the rules in a way that benefits themselves.

I don’t see much in these principles to overcome that problem — the principles seem to be written on the assumption that you are the manager and that you are perfectly virtuous and want what’s best for everybody.

Divvying commons into private property has the underrated advantage that it requires less ongoing management so it has fewer opportunities for corruption.

No one's calling for a ban on opioids because they're already banned — they're DEA schedule II.

This event is a really nice way to try out new programming languages.

> Look at Spain's economy, how it is transformed after Franco died and the fascist regime is removed and the country opens up, gets less centralized.

The graph shoots up in 1960 and slows down in 1975. Franco died in 1975, so your assumption that fascism and central planning hurt the economy is contradicted by the data.

If Wikipedia is to be believed, the actual cause was that the old central planners were replaced by new ones who were actually competent and made policies to support industrialization: https://en.wikipedia.org/wiki/Spanish_miracle

I hope someone can correct me in this thread, but I recall hearing that a single-seat license can cost ~$50k per year. I would imagine that any company with a large number of ASIC engineers would love to reduce that overhead.

Regardless, none of what you said disagrees with the point that EDA tools are complex and should therefore be protected from Chinese influence.
As I understand it, the argument is that the prescription opioids got people addicted and when they could no longer get prescription opioids they turned to illicit opioids.

My point is that the alternatives to a slave being worth 3/5 of a vote for apportionment purposes were a) a slave being worth a full vote, giving the slave states that much more power, or b) possibly no United States at all. Having slave not being counted as a vote at all for apportionment was never going to happen.

And no, the Electoral College wasn't something that the slave states wanted and the free states opposed. As I said, it was a compromise between big states like Virginia (slave) and Pennsylvania (free) versus small states like New Jersey (free) and Delaware (slave). Virginia (and several small but fast-growing southern states) wanted completely proportional representation (benefiting from its large slave population); Delaware and New Jersey wanted each state to be equal; the Connecticut compromise gave one chamber of Congress to each method, and in turn became the method by which the Electoral College apportions votes for the presidency.

Let me repeat:

* The Electoral College was not created or designed to protect slavery, or somehow enshrine it in the Constitution.

* It, and the composition of the two chambers of Congress, were created to give both large and small states a say in governance.

* To the extent the three fifths rule affected the Electoral College, it reduced the slave states' power versus what they wanted, which was a purely proportional system including slave populations.

This sounds like the "Utility Death Spiral" and also happened in Germany, Hawaii, and Nevada.

Best article on it IMO (2014):

tldr:

Renewables require additional grid maintenance costs (storage + two-way distribution) while simultaneously prompting more consumers to buy less conventional energy from utilities. Historically, utilities made money from selling electricity. Now they have fewer customers and higher costs. They have to charge higher prices to the fewer customers. Then more people want to choose renewables. This keeps going until the utilities bankrupt.

The solution is to change the business model for utilities, which are regulated monopolies. So it's a policy question. Absent strong leadership, the utilities tend to claw back against renewables instead of innovating (saga of Nevada)...

>Journalists are currently underpaid

Based on what? Their pay is surely a function of the revenue their content generates their publishers, no?

>Small newspapers are shutting down left and right.

Because the above journalists aren't sufficiently able to engage people to pay for their content.

It amounts to people providing something that few are interested in, or especially sufficiently interested to actually pay for it. How would those providers be deemed underpaid?

Sounds frivolous.

>Is it really free when China had much greater tariffs on US goods than Chinese goods had come into the US? Is it really free when Chinese entities get to enjoy massive subsidies to dump products while foreign companies face nonmarket barriers?

so you are saying that a trade war is successful if there are fewer barriers at the end than at the beginning? That's a reasonable definition, but that would benefit both parties, so it still doesn't really show a "winner"

> And facing the CCP will have a cost.

But if you define a successful trade war as one where there are fewer barriers to trade at the end than at the beginning, that will benefit both parties.

I mean, one could argue that free trade (well, more trade) is going to make your society more free in general, is going to introduce more ideas and things like that, I suppose, and you could also argue that trading more with a country makes it less likely you will go to war with them, but these things aren't really about crushing your competitor.
More Evolutionary Diversity in Amazon Associated with More Forest Productivity
The result in the Medium article applies only to a theory whose theorems are computationally enumerable. In computer science, we need theories that axiomatize subject matter such as natural numbers and computation up to a unique isomorphism so that the objects being axiomatized are characterized precisely. Such theories have induction axioms with uncountable instances. Consequently, the theories have uncountable axiom instances and their theorems cannot possibly be computationally enumerated although each proof can be computationally checked for correctness.

Therefore, a more general proof is needed to prove incompleteness. Such a proof can be found here:

Seems to be an American term? https://en.wikipedia.org/wiki/Socialized_medicine But I agree with what you are stating. (Though if you call that system 'socialized', then the American systems are also 'socialized' to a large extent. So it's probably better to just talk about specific feature instead of such a loaded term.)

The aspect of the system that I wanted to highlight is that routine care is paid for out of the health savings account (Medisave), and not out of the insurance portion.

Another interesting aspect is that the bill you get for treatments always mentions the total cost and any subsidies you are getting. All very transparent.

There's also always a co-pay as a matter of principle, even if it's just a few dollars.

Jeopardizing it as in a problem to solve. No one is saying that this is the end of solar energy, good grief. I'm sure they'll figure something out. The article is just pointing out that it is an issue and it's coming to a head. No one said it was unsolvable. Big oil/coal isn't trying to take your solar.

So well that the anti-battery Liberal Party is funding its expansion.
This is pure speculation, but I could see several scenarios that might produce the discrepancy:

America's fear of regulation results in more workers being injured and developing chronic pain.

America's broken healthcare system means that people are less likely to have access to alternatives such as physical therapy, meditation, counseling, etc.

America's weak social safety net means that people have to relieve their pain so that they can continue working.

Cultural factors result in people being less accepting of pain as part of their lives.
Or forcing people with rooftop solar to get off the grid via intelligent controllers when it's starting to overwhelm the system, since they're the ones inducing the issue.
Do you find you have an epiphany if you don't think hard about it at all ?

That's the thing. Crime-prevention is a plausible excuse. "Normal" consumer's data is mass harvested, profiled, stored, and used for social engineering of some more convenient "normal" consumer.

Same here, more or less. DDG is 'good enough' in a lot of instances but I think it's more that Google has taught some 'bad' searching habits. When I type a random Google search I'm basically expecting it to read my mind (and essentially it does through all of the tracking and analytics); DDG has none of that so the method of searching has to be more specific.

That said, it does't prevent the situation where searching for certain gifs or images gives you a page full of softcore porn, even with the moderate safe search enabled.
While that may or may not be true, I’d say it is true that the powers that be for most countries are in bed with one or more industries comparatively to Australia and the coal industry.
Sorry not everyone in SW Australia has a solar energy supply, so just because you have that advantage doesn't mean others should have to suffer with blackouts. Has the whole world forgotten how to compromise and work together as a society rather than "my solar tribe" vs "your coal/poverty stricken populace who can't afford solar roofs tribe".

One who would argue something like that in the face of the decidedly not free CCP run society that is modern China is fooling themselves. And their mode of operation is most certainly about crushing competitors.

If making smartphones is really as easy as you make it out to be, and smartphone prices are rising, then why isn't that being captured in the global profit share? Considering that Androids are vastly more popular than iOS phones, there would be no reason why Apple's getting 62% of global profits.

I'm a writer (not a journalist) and I'm quite poor. So I pretty often read articles about what is going on with the industry generally.

I'm not going to bother to dig up supporting links. These articles show up on HN quite regularly. I'm also increasingly seeing comments on HN about the poor quality of journalism today.

I'm only pointing out what looks to me like a blindingly obvious connection.

I spent two weeks writing a blog post that hit the front page of HN. It got more than 60k page views and 300 comments and was copied by other people. It made me not one red cent.

I find it really hard to attract Patreon supporters. I'm routinely told "get a real job," never mind that with the rise of the Gig Economy there are damn few "real jobs" with good pay and excellent benefits out there.

So I know firsthand that it takes substantial time and effort to write a good piece and it takes years of experience to get good at writing, but that writing is often de facto given away for free or sold for peanuts so some writer can eat occasionally.

I"m tired of trying to prove this to people who don't want to listen.

The TLDR: If you want actual good writing, you should be trying to figure out how to reward writers who write well. If you don't want to in any way, shape or form whatsoever (because most people on HN use ad blockers) let them get paid somehow, don't be all shocked when the writing goes to shit.
