A small appendix: This is what would happen if nobody controls the grid. Of course, humans and automatic systems do control the grid.

So if you have a gas turbine, and you see it slowing down, you feed it a little more fuel and vice versa.

Unfortunately, solar and wind energy make this impossible. So for wind, the turbine has brakes, but there are videos on youtube where they fail or get overloaded, resulting in burning turbines. I guess solar does something similar (Edit: the braking not the burning of course).

In practice, the non-renewable energy turbines like gas are the easiest to control so these are used to balance the grid.

On top of all of this, running a turbine costs a lot, so there is a lot of grid management going on to decide who can generate which amount of electricity. Decisions made at this level better match the actual load on the grid, or the catastrophic consequences of the post above happen.

Please explain why the parent comment attracted downvotes. In the US Constitution, the first amendment protects Americans' right to free speech. However, not all forms of speech are protected. The same legal principle applies to the GDPR; not all industries need to follow the GDPR, as laid out in the Article 85.
The Day the Golden Gate Bridge Flattened (2012)
The fact that it is such a big problem for so many companies just demonstrates how badly things have been handled thus far.

I'm sitting through tons of GDPR meetings & there are quite a few conclusions amounting to "maybe we shouldn't have stored the data that way".
I fail to see how any of this is offensive.

Do you find it offensive that people prefer to live in countries with a high standard of living if given the choice? Is that somehow disrespectful to the people who do not have that choice? Bringing emotion into this seems counterproductive.

Generally you seem to agree that regulation can be beneficial (if compliance is feasible).

I'm sure you also agree that you'd like the toys you buy for your kids in the US to comply with US safety standards, even when they're made in china, and regardless of whatever standards exist in china?

In my experience, kids find a way to make themselves understood. And their parents will find out -- sooner or later. For things they cannot find out, they probably couldn't help them much anyway.

I find it rather strange to impose a defined vocabulary on them. If such a toddler language would actually be of any use to solve an actual problem, I think evolution would have already found a (then well known) solution.
Writing CloudABI applications in Rust
Out of curiosity, could I legitimately ask Google, GitHub, etc. under the GDPR to delete my name in the AUTHORS file of the git commit it was added in when I contributed to Chrome's v8 engine 10 years ago? Would they have to comply if I did?

Obviously, removing the commit would break git's ability to sign any hashes for that repository after that point…

And thinking it through a bit more, what about the companies that use v8? Could I ask my regulator to get Joyent to remove it from their systems? I'm sure they have copies…
>"any information relating to" are the "unique keys" that you seem to think are not covered. The uniqueness is literally the problem.

The uniqueness is completely irrelevant unless it identifies someone. If there's no way to trace that unique key back to the identity of a natural person, then it isn't an identifier within the meaning of the GDPR and the data associated with that identifier isn't personal data.

>And re: PII, seriously? You're upset because I didn't type out "Personal Data"—even though you knew exactly what I was referring to, as did everyone else? Fight bigger battles…

It's a highly significant difference. Other legislation talks about "personally identifiable information" - in the US, NIST define a finite list of things that constitute PII. The GDPR talks separately about "personal data" (stuff you know about someone) and "identifiers" (the information that ties the data to a natural person). Lots of stuff that isn't PII is personal data. Data can become personal data through association with an identifier or cease to be personal data through anonymisation. Apropos of nothing, PII isn't necessarily personal data. Without that distinction, large parts of the GDPR are incomprehensible.

> they increase prices of goods which are advertised

I think that's completely false. The price of things goes down with volume, and if no one knows about something its going to be far more expensive than something everyone uses.

Advertisings entire purpose is to increase the volume sold, which lowers the price.

Levelized Cost of Energy Analysis (2017)
As others have said, if nothing is done about the energy excess, it goes into an increase of the frequency.

In Germany, there are 3 different steps to handle this (I guess it's pretty much the same in other countries too).

1. The primary reserve power is short-term fine-grained capacity that takes effect automatically (is not requested by the TSO[1] explicitly) if the frequency leaves the +-0.01 Hz band around 50 Hz. The capacity is then provided proportionally to the distance, full capacity is supposed to be provided when the frequency goes under 49.8 or over 50.2 Hz. The tricky part is that the capacity needs to be supplied in both directions which can for example be done by modulating the frequency differences on a power plant running slightly under its full capacity. In Europe, this capacity is provided jointly spread over the whole grid and totals roughly 3 GW in both directions (e.g. simultaneous full outages of two large power plants).

Broadly speaking, primary reserve power is supposed to stabilise the grid, i.e. to stop a frequency in/decrease.

2. Secondary reserve power is supposed to kick in after 5min, latest 15min of primary reserve power usage. This is done automatically by the individual TSOs (in Germany we have 4 because we can :)) if the reason for the deviation is in their grid, and sends a request to a controller in the providing power plants, which have to provide 1MW 1min after the request and full (sold) capacity after 5min. It's not as immediate as primary power as the to-be-produced capacity is not directly calculated from the frequency, but the request messages still change quite frequently, usually a few times per second.

This part is supposed to move the frequency back to 50 Hz.

3. At last, if secondary reserve is drawn for too long, minute reserve power is activated. This is just a straight "you have 15min to provide 50 MW, 30min onwards after you start". It's essentially just an economical optimisation on the process, since due to the higher lead time, conventional power plants can actually start up to provide it, while for both secondary and primary reserve power they need to react so quickly, that a full ramp-up wouldn't be efficient.

Back to your main question, on how negative reserve power is provided then concretely, this could be:

- Downmodulating running power plants (primary, secondary and minute reserve)

- Charging batteries (likely just primary and secondary reserve since minute reserve would exceed capacity)

- Starting up additional consumers (minute reserve)

- Running turbines without actually producing any power (worst case minute reserve)

- Shutting of wind turbines by turning their rotor blades (likely just secondary, can't be provided guaranteed for long due to changes in the wind, would be fast enough for primary reserve but can only work in one direction)

This sounds very odd to me.

Most wind turbines built today with a capacity of over a few hundred kW are not synchronised to the grid frequency.

They run at whatever speed they can run at with the current wind speed, which is converted to DC, goes down to the root of the wind mill and gets converted back to regular 50Hz AC when it's put into the grid. They only thing that could happen there is that this converter station blows up.

Also, those modern turbines always have turnable rotors that can just be moved into a longitudinal position relative to the airflow, stopping immediately.

I've kept myself to lurking in those threads, simply because there's been so much FUD about this for the last few months. This, however, is spot on and it needs to be pointed out.

If people think GDPR is bad, then they should have a look at what it takes for a small startup that want to sell chicken eggs for breeding purposes, especially if you buy/sell across the EU borders. The requirements are quite insane compared to GDPR. :)
For what it's worth, the clocks are back in sync.

The cloud providers provide a lot more than the VPS providers:

- Arbitrary private network topologies

- Managed databases

- Other managed services for the "undifferentiated heavy lifting" of infrastructure like source control, CI/CD, monitoring, log aggregation, alerting, load balancing, encryption, directory services, etc.

As such, they're in a different business - providing single servers for hobbyist and small-business websites - rather than seriously competing with on-prem for big-co infrastructure needs. They're making some attempts to catch up but are far behind.

Be aware that there are two lists in the partners page. You could easily miss it since the other is behind a greyed-out tab called "Other partners" or something like it, which contains another 100 partners or so, in addition to the 200-300 main partners Verizon will share your data with by default, unless you opt-out (illegal under GDPR).

Verizon-owned sites that use this policy include Engadget, Techcrunch, Aol, and Yahoo.

Some more info here:

https://gdprhallofshame.com/5-techcrunch-engadget-and-oath-c...

Even though it's opt-out, at least they let you use their services when you deselect all of them - although I don't really trust a company such a Verizon to live up to its word and not actually track you, even if you deselect all of those partners.

However, companies like Google, Facebook, and Twitter seem to only give you the "option" to "take it or leave it": either agree to their terms or you'll lose access to the account (also illegal under GDPR). That's also why noyb is filing complaints against them (although they missed Twitter):

GDPR is happening because for the last several (10s?) of years companies have been playing fast and loose with people's data. They've had their chance and they've blown it fairly comprehensively.

The people (by and large government is run by the people, for the people, at least in some countries) have had enough. I've had enough, and this is us telling companies they've had their chance and not made the grade so we're dictating now. As a person, and father (who has to worry for the rest of my live about my offspring's health and happiness, and linked to that, privacy) I'm very happy with this law. I support it, as seemingly a lot of people do. That's not authoritarian, it's the will of the people.

And no, I'm not some sort of communist beard stroker, I'm pretty central in my political beliefs and I also don't appreciate governments sticking their noses in where it's not welcome, but this, this is welcome.

Nope. Used Bookstores is correct.
I couldn't disagree more with your understanding of the legislation.

If I discovered your company was storing my personal data under "unique keys" that considered by themselves didn't personally identify me, I'd report you to my GDPR regulator immediately.

Unique keys with no personally-identifiable data in the key aren't some sort of innovative workaround that will allow you to store my personal data without my consent. It's not even remotely consistent with the spirit of the law, and IMO, with the plain text of the legislation.

> I think that's completely false. The price of things goes down with volume, and if no one knows about something its going to be far more expensive than something everyone uses.

That applies between companies (where you have real competition), but does it apply over a marketplace? And even if over an industry you were able to persuade more people to buy more product, is that necessarily delivering value for the customer? Wouldn't it just be better if they found things by going out and looking for them if or when they need them, and soliciting expert advice?

The obvious example is pharmaceuticals, if patients seeing adverts leads to more prescriptions for a particular drug, is that a good thing? If the pharmaceutical industry manages to get people to take more drugs, is that a good thing? The unit price might go down, but that doesn't mean utility for the consumer goes up.

Everyone mourning the death of targeted ads:

It's perfectly possible to do targeted ads without collecting personal data! You just keep personal data where it belongs - on the user's computer/phone - rather than stealing it.

Keep the personal data in local storage, have the logic that chooses ads run locally, and you have targetted ads without invading anyone's privacy.

I don't know if that satisfies the GDPR - not a lawyer. But it would satisfy me.
What a ride. I really disagree with almost everything that's written there. So many things are even factually wrong, or with such a limited perspective that they are very likely missing the point. For instance, what he describes is not project management (limited timeframe, specific end result) but constant, ongoing product development. He describes a development management job (might also be called team lead), not a PM job.

His conclusion seems right to me, though. Team management doesn't need fancy processes. The overview of activity and backlog needs to be there and the manager has the responsibility to enable syncing between activities and to the outside world.

If one calms down after that conclusion, one realizes that managing a single team of developers is trivial. Maybe that's why people are not talking about it so much (in contrast to "nobody gets it")?

The art is in reprioritizing existing tasks when new ones come in (because usually something needs to get dropped), and additionally there's art in handling the meta level when single processors of a team are not just people but subteams.
My knowledge of turbines is about a century out of date, so please be so good to add everything you know to this discussion.

As I understand it:. It used to be that every turbine on the grid was synchronized and people found out how the grid communicated its energy behaviour by changing frequency. This happened as emergent behaviour, almost by accident.

As the grid operators came to rely on it, newer technology has to emulate it.

But today, most of Europe shares the same grid, which was impossible at the time. There have to exist technological advances to make this possible. And solar doesn't even have an inherent frequency, it's DC. So what you say sounds very reasonable.

But I hope never to see from close by what happens if modern energy equipment fails catastrophically.
Completely false. As volumes sold ramp up the company makes more profit per unit, it's almost unheard of to cut prices. Competition on the other hand can lower prices.

If anything these days they tend to increase price as market share increases.
It turned it from a monetization-scheme to a donation-based scheme. Let's not lie, we know these don't work, we all know the ruse.
> Advertisings entire purpose is to increase the volume sold, which lowers the price.

Problem is, if everybody does advertising to compete for market share, the prices go up globally, because the entire ads industry consumes resources.

But for now we haven't figured out any better model. We might in the future, or we might not.
