I'm having trouble with this article... where is the lesson they learned? No offering of what the newest generation is pursuing with naive and reckless abandon? What about what they believe currently about how a global world can be structured? How would they have done it differently if they could do it again?

Sounds like they got relatively wealthy and powerful by building this internet they're disappointed in. If they feel guilty, are they working toward redemption?

I appreciate the willingness to admit when one has been wrong, but this sounds to me like the person who has too much to drink, spills their cup all over your floor and goes "whoops, my bad, watch out for that punch, it's strong stuff..." and then walks away to get another drink while their spilled one soaks through the rug.

However, remember not to take a 99-year-old book literally as a style guide.

Strunk & White contains some timeless advice. Most (but not all) of the habits it identifies as bad writing are still considered bad. But for positive examples of how to write well, you can't follow the example of a book from 1918. Its language is inherently dated and it predates linguistics as a science. You need a newer style guide.
- The negative prices are always temporary, bounded in time and price by the cost to spin down a generator

- Only the major industrial customers actually see the negative rates (residential customers are still paying retail)

- In many regulatory environments the electric utility and power generators are different companies, so only the generators are at risk of losing money and shutting down plants
It is only true because there is a second hand market that trust this is the correct price. Seeing how those devices need to move technically with their time (more powerful hardware), I fail to see the attraction of a device that would be well passed its prime, specially with a battery that isn't replaceable.

Yes, very large government subsidies created the current market situation in Germany. But, note that "very large" is only relative to typical subsidies of wind and solar in other countries. Also, all electricity markets in developed countries are pretty much completely regulated and the economics of electricity are determined much more by a combination of regulation and indirect subsidies than they are by anything remotely resembling a simple definition of market forces.

In the United States, for example, we have an extremely complicated mixture of local and state-level economic, infrastructure, and supply regulations, environmental regulations that are mostly federal (though also state), zoning, eminent domain, and other kinds of permitting. Then, alongside all those, we have massive subsidies of electricity distribution infrastructure, extraction of coal and oil, transportation, and "homeland security." Finally, we also have relatively small subsidies for wind and solar.

Germany made a policy decision some years ago that public subsidies of renewables would create large positive social externalities. So, yes, the money goes around in a circle, but -- to over-simplify -- in theory creates more money (technology development, improved resistance to economic shocks, jobs, public health) and better outcomes of various other kinds (public health, reduction of climate change risks of various kinds, reduction of risk from nuclear plants, perceived electoral advantages by the political parties in power) as it goes around.

"Mesh" (in thick air-quotes) here is just a way for self-organizing for shortest uplink hop count.

Strict uplink-downlink hierarchy still stays regardless of whether "manual uplink" or "mesh" mode is in use. Each repeater doing Source NAT still stays. Lack of "sideways" connectivity still stays (unless you configure manual DNAT which is incompatible with "mesh" mode to begin with).

I.e., if you have 3 of those ESP8266 repeaters with two clients connected to different repeaters, there is no (easy) way to have those two clients talk to each other. Let's say this is our network diagram:

{The Internet}----[Cloud Server]
|
[Wired AP]----[Local Server]
|
[ESP8266-R1]
| |
[ESP8266-R2] [ESP8266-R3]
| |
[Clinet 1] [Client 2]

...then, we have two options how to make Client 1 and Client 2 talk to each other:

- each client talks to the same server (local or cloud) and server takes care of passing the message;

or

- we configure static destination NAT (option portmap add) on both ESP8266-R2 and ESP8266-R3, and disable "mesh" mode (i.e. manually configure uplinks for all 3 repeaters);

...and arranging 1000 of those in a single string and routing a single packet through that is better avoided. "Mesh" mode helps a lot with this, by selecting shorter path to the internet and bringing topology closer to a tree, where possible.

> Being alerted to vulnerabilities in your installed packages is nice, but
there's simply no need to be doing this operation as root. The dangerous
combination of laziness and poor software design is quite prevalent here.

Just a thought - if an unprivileged user could download the vulnerability list, couldn't a malicious but unprivileged local user just "download" an empty vulnerability list? At least it would take a user account created specifically for this purpose. (Which I admit would be a good idea!)

That's true of any modern general-purpose filesystem, for all OSes - there's a reason why embedded devices often enough speak only FAT32, and some even only FAT16.
Tristram Harris [1][2] is worth listening to on these points, I'm sure many on HN are already aware.

Without rambling too much, I'm one of those over-sensitive, slightly aspie types that reads SSC and gets carried away with over-analysing the zeitgeist. Uncharitably, you might say 'smart but weak-minded'. The longer I spend in front of social media, the more and more in tatters I feel. I spent a week entirely disconnected from the 'net a month ago and I can't stress how restorative it was for me. Though, alarmingly, I was back in full swing soon after I returned.

For those of you who have problems with self-control and sustaining your attention, and think it has something to do with your browsing habits, I highly recommend you - I urge you - to disconnect in a significant way. Of course it's up to you what that means.

In September I gave up smoking, and the physical and psychological changes I underwent were pretty surprising. I felt more present and in-the-moment (and other barely-describable-but-definitely-nice feelings) than I had done in years. Despite smoking 25 a day, I have found quitting Reddit much, much harder; despite being convinced it's as bad for my mental health as smoking was for my physical.

I think there's something to be said about identifying addiction patterns in your life and exorcising them. The small amounts of progress I've made recently have certainly felt as though they've increased my net level of agency and free will. I wish that flowery metaphors about demons were more readily acceptable, because software is a lot like wizardy - and it really does feel like dark sorcery has been cast to possess the West.

Well, the data did include Bitcoin's first rise above $1000 and subsequent crash (which most people called "a bubble"). If you had bought right before that one "popped", yes - you would have waited a while to be back in positive territory, so that's one time window where you might have lost money compared to the algorithm, but only if you were impatient.

No, residential customers still pay retail. I believe only major industrial customers ever see the negative wholesale rates.
I too grew up during the dawn of the Internet and "information age" in general. It was a wonderful time to be living, and an even better time to be a teenager -- we had such a leg up on the previous generation because we KNEW the 'net was going to be huge, and most of them thought of it as just another passing fad. I have fond memories of even pre-Internet, dialing into local BBS' on 28.8 baud modems -- which of course led to discovering "phreaking" to get free long-distance calls to dial into the non-local BBS' (hey, I was a teenager remember). Such great memories.
IRC was, and still is, incredible. But I can't bring myself to lump the current day 'social media' (ie; Twitter, Facebook, etc.) into the same category as IRC. Yes technically I guess it's in the same vein, but there are no "likes"/hearts/thumbs-up-or-down on IRC -- it's just a vast open public forum for almost instantaneous text-based chat, for better or worse (better, IMO). That whole likes vs. dislikes thing which is far too central and too much of a core part of current social media platforms. It's way, way, way too easy to use as a tool for manipulation -- and if anyone thinks they are NOT doing this, they are sorely mistaken.
There's a case to be made that advertising is really the central issue with Twitter/FB/etc. They have to keep people's eyes glued to the platform in order to show them more ads in order to make more money. That business model isn't going to end well for anyone except the advertisers.
It’s a truly broken system. I always answer 10 for call center employees, because often they’re not empowered to actually fix anything, and answering anything else often hurts that person instead of shedding light on the broken system they’re stuck in.

The only time I answer less than 10 for a CS person is if they’re actually rude or not trying to be helpful. I much prefer the surveys that ask multiple specific questions that split the interaction between the rep and the outcome.

Yes thats exactly correct. There is a balance between what is made and what is used, it must balance out. So it takes time to ramp up or ramp down, or even control ramping when the wind is blowing...it seems. So to keep that balance (i guess) at times it makes more sense to drop the cost to below zero.

At least that's what i picked up from a youtube video about the topic a few weeks ago.

The article doesn’t actually answer the questions it purports to answer. Better source: https://www.cleanenergywire.org/factsheets/why-power-prices-....

Energy markets are artificial markets designed to create various price signals that result in certain incentives on both generation and demand, subject to numerous constraints. One constraint is that demand and supply must balance. The grid can’t store much energy. Oversupply can cause grid frequency to go above 50/60 Hz, threatening grid stability: https://www.e-education.psu.edu/ebf483/node/705. Power prices go negative when there is too much generation capacity online at a given instant, relative to demand. That creates incentives for generators that can shut down (like natural gas) to do so.

Negative power prices are not a good thing for consumers. A negative price in the wholesale electric markets does not mean the electricity is "less than free." Obviously, even wind power or solar always costs positive money to generate in real terms. Instead, it signals a mismatch between generation capacity, storage capacity, and demand. In a grid with adequate storage capacity, negative prices would be extremely rare.
Couldn't you just make a single transaction with all of your BTC you currently hold (provided you've held it in the same wallet for recent history, when all these forks have occurred), then cash out all of your forks/airdrops using the old secret key?

You still run a small risk that a shady fork/airdrop could try to use your secret key to transfer other forks/airdrops, but you would avoid the risk to your BTC holdings.

I accidentally* drove past the US southern border into Tijuana from San Diego without passport control, there was only an automated plate reader managed by US CBP. I also did not have my passport or passport card on me.

Coming back the same day, there was a line to drive back into the US that took several hours. Luckily, I was allowed back in with a driver’s license by the agent.

*I was dropping off 2 American friends who were taking a day trip to visit Tijuana, but the road signs were terribly marked and I crossed over unintentionally.
>if executives want a simple metric that is better than NPS, a random number generator is the fastest and cheapest way to achieve it
>In fact, NPS measures nothing in particular.

These types of sweeping statements aren't a helpful way for the author to advocate his broader point.

The strengths of the article lie in the more detailed points which bring to light some great examples of how NPS, and surveys in general are mis-used (and some examples that don't actually manifest themselves as real problems in daily use very often).

My thoughts on the examples chosen above:

>50% or more of their data filled with arbitrary numbers

I'm not sure what this refers to, but the way the NPS equation works, every respondent's score matters and mathematically impacts the overall NPS (each one feeds in as either a promoter, neutral, or detractor). Some of the author's own recommended questions include only 3 answer inputs also.

>Not collected from state-licensed specialists

Almost all operational data collected by companies for management reporting is not collected by state-licensed specialists, but is still useful.

>Easily gamed

All survey questions could be gamed in the ways similar to the article examples. A good executive will make sure the survey is asked in the same way of his own organization as of those of peers, and in the same manner over time. He or she won't let agents do things like cherry pick which customers to survey, otherwise the money he invests in the survey wont' actually help him run his company.

>Shareholders should insist the numbers be corroborated by a neutral third party

Correct, companies who are serious about measuring NPS accurately do often hire third parties to run surveys (see example of JD Power running NPS: http://www.jdpower.com/press-releases/bain-certified-net-pro...)

>NPS recommendation question taints followup questions

All survey questions can be tainted by preceding questions. When writing a survey it is fairly straightforward to A/B test the order to make sure this isn't a major factor.

Exactly, they can't remove base load power plants because they need them for times when solar and wind output are low, and 'peaker plants' are incredibly expensive. (which are activated in minutes, instead of hours/days) By adding battery (like the 100MW project in Australia) they can remove a few older base load plants, and handle spikes with batteries, instead of peaker plants.

Let me tell you why that can not happen: All the Chinese government officials are desperately avoid losing face. So that can not happen.

What I said that's your illusion is based on an naive assumption that you didn't fabricate a story. There are many readers familiar with Chinese society and how it works here in HN.

" Name a composer from 1300s or 1100s."

There were no composers then ...

Musical theory only developed during the renaissance and was basically formalized by the baroques i.e. Bach - and Moazart/Beethoven mastered it.

Music as we understand it really didn't exist before that. No real way to write it down, no way to create complex arrangements.

Italians thought of it, Germans formalized it and then mastered it. Nobody has pushed it much further since.

---> Scientists ...

Aristotle, Plato, Archimedes - not Scientists, but I get what you are saying - again I'd suggest that these are 'fundamentalists'. Founders of rational thought.

Newton = foundations of classical physics.

There are 1000x more Scientists alive today than ever before, and the only one we're going to remember is from 300 years ago? Point being - maybe there are no easy/major discoveries to be made so nobody will be remembered. Who will be remembered for CERN? Probably nobody.

A bit dated (2011) though touching on the economies of power generation, "The High-Stakes Math Behind the West's Greatest River" ( https://www.forbes.com/sites/jonbruner/2011/10/20/the-high-s... ) is an interesting read.

From the NYT article about Germany:

> At the same time, other mainstays of the country’s electricity supply, especially some coal and nuclear power plants, are unable to dial back quickly enough, leading to negative prices on electricity trading markets.

From the Forbes article about the Columbia river (Oregon / Washington):

> issue is what happens when too much electricity is on offer. The enormous supply of hydroelectricity during spring runoff can push electricity prices to zero—the BPA gives away electricity to local utilities for free when it’s forced to produce more than it wants to. Since wind producers enjoy production subsidies, they can push rates below zero, effectively paying other utilities to switch off their generators. Last winter, the BPA told wind producers under its balancing authority that it wouldn’t pay negative rates to them during high-water events.

This gets more complicated when you also take into account the non-power constraints on hydro generation. Environmental concerns limit how much water can go over the spillway (which hyper-aerates the water and increases turbidity... which is bad for the fish. http://www.oregon.gov/deq/FilterDocs/Coltmdlwqmp.pdf gets into this including the water standards act.

> The concentration of total dissolved gas relative to atmospheric pressure at the point of sample collection shall not exceed 110 percent of saturation, except when stream flow exceeds the ten-year, seven-day average flood. However, for Hatchery receiving waters and waters of less than two feet in depth, the concentration of total dissolved gas relative to atmospheric pressure at the point of sample collection shall not exceed 105 percent of saturation;

The interconnectivity of all of these factors is quite interesting to me and one of those things that is much deeper than a simple management of the power market.
