My residential electricity supplier sent around letters last year to every account offering what amounted to "water pipe insurance". Mind you, this was the "electric company", offering "water pipe insurance" but the deal was that for some "low monthly payment" amount (I forget now how much) they would cover the costs of fixing a leak between the locality water meter (installed street-side) and the pipe that entered through the wall into my basement to supply the house.

The letter was full of scary sounding things that /might/ happen, and of the huge sums of money a leak might cost to repair, should one occur (this figure I have some recollection of, their claim was that it was on the order of $3,000-$4,000 to repair).

I read it over, scoffed at most of their scare tactics, and recycle binned the letter. But I did wonder just how many folks would ultimately sign up for the "insurance".

Since you are new to HN, you may not know this, but it is considered poor form to complain about being downvoted. And more often than not, it invites even more downvotes as a result.

From the HN Guidelines (which I recommend reading):

If it bothers you this much, you're better off deleting your comment.

Yep, I was mistaken. I didn't reach the end of the article apparently the first read.

I do agree that is problematic and silly.
For a real life example, there is a group of people that collect Facebook posts and process them through a ML filter which judges if the post contains hate speech, and if it does, it reports the post to the police, supposedly after manual review.

Does this processing comply with GDPR? I'm pretty sure none of the people would allow this processing to take place if they were asked for permission.
The innovation here is that they made the atomic clock portable enough to be taken to the top of a mountain, so that they could use the difference in clock speed to calculate the height by general relativity.
There are some nice exercises here, good work.

For question 48 it might be simpler to just write

np.sort(a)[-5:]

instead of using argsort() and then using fancy indexing. Better yet, use

np.partition(a, kth=-5)[-5:]

which scales linearly with the size of the array.

Also, the one-hot encoding puzzle (51) would be more efficiently solved using

(arr[:, None] == np.unique(arr)).view(np.int8)

In general, `for` loops over NumPy arrays should be avoided where at all possible.

In my opinion, it was a great tragedy that Chavez is not still alive today. Now people can say ridiculous things like this. If he was alive today, Venezuela would still be collapsing and it would be clear whose fault it was.

I am probably an exception, but I actually love this monoculture. I don't have to explain to anyone that I work at Houzz and get blank stares. The monoculture also has advantages of adopting things quickly. Like Tesla cars were on the road here earlier than anywhere else. Or adoption of Uber / Lyft etc. It almost like a glimpse into the future. And as someone pointed out, many of these companies are not "tech" strictly. Something like Mozilla is a tech company. Tesla is an automative company that takes advantage of technology. So it is not like this monoculture only talks about React native.

Sorry, what word?
True, Stuttgart as the biggest cluster of German car manufacturing has been the epicentre of the German pollution-debate (that was based around particulate matter, not NOX).

The Diesel has become somehow the victim of this (sadly, since as mentioned by other commenters here, Diesel cars have their advantages).

The reason Stuttgart is Germany's pollution capital has almost nothing to do with the Diesel but:

- its topography, being a city almost completely surrounded by hills, thus unusually hot and windless for a German city

- the upper class areas on the hillside/slopes are the main polluters with houses dating from ca 1900 and/or re-equipped with pellet heating systems that were subsidized because of energy footprint while being even worse pollution-wise than even older heaters

Both of these points are validated by the fact, that it's not the weekends when the pollution calms but its the winters when there is almost a daily pollution warning - its when the rich people heat.

Even the plaintiffs in the other recent (particulate matter focused) important German pollution case complained that a Diesel ban does nothing for the pollution situation: The main source for car based emissions aren't the engines - but the wheels.

This seems to be just the prototype. Ideally, the production version would have the PCIe interface reader hardware on the system itself, and the SD Card would merely expose some bus pins.

Another solution might be keeping the PCIe interface on the SD card but adding a small proxy in the reader to restrict the PCIe protocol - but this might incur a non-negligable performance hit.

It is true that societies are experimenting with policing what people say online; Germany's attempts to combat hate speech and fake news come to mind. But that is (hopefully) different from punishing political dissent.

Ask HN: how can WiFi captive portal web pages affect iOS hardware keyboards?
There are many reports [1] of this unsolved issue: external iOS keyboard (bluetooth or smart connector) works until authentication to some WiFi captive portals.

Theoretically speaking, how is this possible? Could a wifi access point send incorrect management frames that affect the hardware chip that handles both WiFi and Bluetooth on iDevices? Why would that affect non-bluetooth keyboards that are physically attached via Smart Connector?

> The energy used to create a good is usually significantly more than the energy the good itself uses.

Not when you're talking about a cheap consumable product which mostly converts power into heat. A 75W bulb is about $2.50/yr worth of energy consumption per hour of daily use at $0.09/kWh. An LED equivalent is +/- $0.35/yr at a cost of $3-$6.

Maybe 5%-10% of my home's bulbs weren't worth replacing out of cycle, but LEDs are so cheap and the overall savings so high that it's not even worth thinking about.
I've verified that antibiotic creme and bandage work better than bandage for myself. I understand ~10% have allergic reactions. Are you optimizing for a corner case?
Sure enough looks like your privacy policy explicitly states that 3rd parties aren't going to be receiving our PERSONAL data. Thanks for the clarification. I think that covers one's worries about personal (identifiable data).

My point was more about data that is no longer personal. Couldn't you for example still collect and run analytics on user data, which you could sell to 3rd parties as generalized "hey people are talking about your product X"?

For instance maybe you track discussions about specific tools in the tech industry... Let's take IDEs as an example. You could build a portfolio of useful data to Microsoft about the sentiment toward their Visual Studio system.

I'm not saying you guys ARE doing that, I was just attempting to answer the question of why investors might opt to jump into this (crowded) space. I have no problem with that kind of data collection btw. It's the personal stuff I don't like :) . Whether you're collecting non-personal data doesn't really matter as long as you're not selling identifiable info (which your privacy policy clearly states you are not).
One thing I enjoy about charging more is the retention rate, it might be counter intuitive, but if you have a product worth keeping people will pay for it. Those customers will likely stay on longer, wont complain (as you pointed out), etc.

When you go for the lower price point, you're getting people less in your niche and thus want more bang for their buck, or really want a different product entirely.
What I am trying to say is - I don't belive that this is an obvious form of corruption, pribes and so on. This seems at that scale very unlikely in any Western democracy.

But I find suprising that over the last years it became obvious that electric cars are not the choice for the largest majority of any new car buyers. But all of the sudden the car manufacturer industry is having a scandal (aparently mostly in Germany) that becomes such a manficent scandal that is reaching a dimension never seen before. As a result a large number of cars is most likely going to be taken out of the market that would have never been replaced that early on.

Besides from kicking out a few employees, updating a few models and paying fines, the latter both probably covered by their insurances, the companies have no real consequences experienced. Sales and revenues seem to be stable and a few % changes in brand reputation are not going to hurt them either. Ultimately there will soon be a lot more cares purchased at a time where Tesla is still not mainstream ready.

> [Jevons Paradox] It is not related to the cost of the final product.

I don't believe that's correct. From the Wikipedia article:

"Goods and services generally use more than one type of input (e.g. fuel, labour, machinery), and other factors besides input cost may also affect price. These factors tend to reduce the rebound effect, making the Jevons paradox less likely to occur."

So the rebound effect is explicitly related to price elasticity, with the critical term being "price". If the cost of an input contributes less and less to the price of the final output, why would one expect it to have any effect?

> Humans would happily use vast amounts of electricity 24x7x365 our entire lives if it is available.

I really don't see any evidence for that statement (and indeed the parent article is providing clear evidence to the contrary). Humans want their needs attended to, and to the degree that electricity correlates to that, they'll have an appetite for electricity. To the degree that it doesn't, they won't. Nobody actually wants to use vast amounts of electricity simply for its own sake. Moreover, there are human desires that are inversely correlated with electricity usage, such as quiet, dark skies, etc. One would expect those desires to exert a downward pressure on electricity demand even if it were completely free.

It seems obvious to me that what is happening here is that in essentially any good or service you can name, non-energy costs (labour, materials, land, etc.) are becoming a much more significant component of price, both due to decreasing energy costs and increasing energy efficiency, as well as intrinsic rises in the cost of labour and materials. This in turn limits the ability for the cost of electricity to significantly stimulate or repress demand. Seems pretty straightforward.

Excuse me for being direct, but do you work for a record label?

Not at all, I'm an independent artist at Bandcamp. What I am saying is that without marketing you have 0 sales.

I'm also not saying that there are no artists who can do the marketing themselves (through social media, etc., as you mention). Most artists, however, neither have the time nor the connections to do that.

It's the same effect as with app stores, where also just a very small number of developers make any money. You're right that Bandcamp offers a sales channel,of course. That's essentially all that these alternative distribution channels offer. We can debate whether that's worth 15% of the sales, though. As I've said, it works for some people who are well-connected and have a natural talent for self-marketing. For most of the artists, it doesn't work.
> It helps to put yourself in others' shoes, and ask yourself how much time/energy you, as a startup founder, would be willing to put into regulatory compliance with Canadian/Russian/Indian laws.

If I were to target my business at Canadians, Russians or Indians I would definitely make an effort to comply, especially if those laws in general did not originate from protectionism or were particularly hard to implement (which I don't think the GDPR is, at least not in spirit).
The Origin of Charlie Root on BSD Systems
Here's a fun stat: a few years ago, I surveyed some of my fund's portfolio companies and asked, "for a similar level of product/service, how much higher or lower are your prices compared to your initial pricing?"

Out of a dozen replies, about 10% were pricing their product lower, 30% were pricing the same but taking higher margins, and 60% companies were charging 2.5x-6x more than they used to. Median was around 3.5x. So the majority of companies had marked up their prices severalfold, and only one company had lowered their prices.
