There was confusion on Twitter how a frequency drop could cause a power outage. It's the other way around: loss of power/a plant leads to a drop in frequency. Here's why:

Imagine a generator spinning at 50 rpm (for the sake of simplicity). Now if the load on the generator is larger than the power it can provide, it will be slowed down and the frequency goes down. If the load is lower than the power output of the generator though this surplus goes into spinning it up, raising the frequency.

There are plants that can more easily vary their output which are used to manage these fluctuation and providing frequency control.

A pretty new and fast one is the Hornsdale Power Reserve in Australia, based on Tesla Powerpacks which can react in milliseconds, instead of seconds and minutes.
This is a very cool project and a bad business idea. I cut my own hair with a Wahl trimmer. Have you gotten liability insurance quotes for this yet?

I am not trying to be a buzzkill but you are going to knick ears, pull out small chunks of hair, and other minor trauma on customers if you try this. You want to have that liability insured and if not you might put yourself in personal financial or legal jeopardy, regardless of legal waivers (IANAL).

I used to have a job where I analyzed global ship tracking data (AIS and other less-open (i.e. more classified) data streams) for law enforcement and environmental conservation purposes, and learned one thing: man is AIS data a bitch.

This is especially true when you're dealing with potential bad actors who can spoof their transmissions, combined with incredibly poor vessel metadata databases and strange satellite AIS coverage issues.

If there are any data scientists out there looking for a real head-basher, start an AIS project.
Oh I see. My reference for energy consumption is wikipedia. When I was trying to dig for the primary source yesterday I found the link was dead and the equivalent live location of it (IEA key world energy statistics) was behind a paywall. I didn't expect such a large discrepancy between the wikipedia reference and other sources.

I can already see how something like this will further increase inequality due to unaccounted biases in the training data, for example worse no emergency response in black neighborhoods because there is less data about them.

The question is whether this bias is better than just relying on government agencies, which we know are absolutely infested with racists and fascists.

> To a layperson, the measure of philosophy is something like the moral and mental well-being of the philosopher. That is why the laity cares and most would say should care about philosophy.

...As exemplified by the fact that all transcendentally popular philosophers were moral, "mentally well" upstanding citizens. You know, like Nietzsche, Ayn Rand, Kierkegaard, Wittgenstein, Heidegger, Sartre, Lacan, Bertrand Russell, etc.

> It seems likely to me that the reason laypeople so consistently criticize more educated philosophers is that philosophy optimized for social validation is not optimized for moral well-being

Stop trying to imply consensus where none exists. Brushing an entire academic field as a social validation circlejerk is an intellectual fail state.
This was the original article that talked about this attempt: https://robertheaton.com/2019/06/24/i-was-7-words-away-from-...

HN discussion: https://news.ycombinator.com/item?id=20283922
My motivation is calling out what the possible motivation for the article is, which is my duty and right, as a member of the HN community. I can weigh-in just like the author of the piece did.

Statements like:

By most measures, the global economy is in the midst of the deepest slowdown since 2015, and in many cases since 2009.

The author goes on to explain that:

the problem has stemmed from trade policy, which has turned sharply protectionist and attempted to remake global supply chains.

Yes, things are changing, and like pouring antiseptic ointment on a burn, it can sting a little. The turning of a big ship takes time, longer than it took to create this article and make it seem we are off-course.
Regardless of whether or not vigilantism is ever justified, I don't think that killing someone that has made a credible threat which law enforcement has shown they are unable to protect you against is equivalent to killing motivated by racism.
An Overview of Logic in AI and Machine Learning
I've heard of local GDPR complaints and enforcement actions (no fines yet, in administrative proceedings) against various state agencies, municipalities and also hospitals, so it does apply to state institutions at least to a certain extent. They have it a bit easier with the reasons for processing, as usually there's an existing law that mandates (and thus allows) the data processing they do, so they usually don't need consent, but the other requirements should apply.

Why wouldn't GDPR apply to german KdöR? I'm not aware of any exemptions in GDPR that could apply to them; governments can make specific local exceptions for national security, defense, judicial process, etc needs (https://gdpr-info.eu/art-23-gdpr/) but Germany shouldn't be able to simply exempt all their KdöR.

One thing is that in some jurisdictions public institutions can't be required to pay fines to the regulator (because transfering money from one gov't pocket to another doesn't make that much sense), however, you can still get an administrative ruling forcing them to change their policies, and if your rights have been violated, then you're entitled to compensation, the "can't be fined" only applies to stuff they'd owe the regulator, not regarding harmed individuals.
Is everything going to be blamed on the Russians now?

I mean, its only fair .. sure .. after all, the West has been blamed for so many fucked up things throughout recent history - the destruction of the Middle East, the failure of financial markets, the massive losses of the middle class throughout the 5-eyes nations, the grand propagation of myths and lies about WMD, and so on .. but is this really fair game?

Got actual evidence that Russia is engaging in aggressive cyber-warfare? Yes? Then show it.

Otherwise, please shut the fuck up with this nonsense.

> but the question can be broken down into many other sub-questions which can be answered formally, with a smaller core of sub-questions that are necessarily empirical.

I don't think this path is particularly fruitful, though. For one, the question of cost is still empirical. For another, researchers who study technique X are interested in answering the question of what it can do, but developers are interested in an entirely different question: of the many techniques of achieving their particular correctness requirements, which is the cheapest? This question is clearly empirical.

After all, engineers ultimately care about one thing only: the probability of system failure and its severity vs the cost of achieving this correctness goal. Since none of these factors is ever zero, I don't think the right path is to separate the layers and pick which ones we want to dial to 100%, especially when considering that at each layer, the difference between 99.99% and 100% can be 10x in cost. I think that a more holistic view is suitable in the vast majority of cases, which means that we may prefer less than 100% certainty at all layers. In particular, dialing some layers to 100% is almost certainly not the cheapest way to achieve some realistic correctness goal. Put differently, the mere fact that you could achieve your correctness goal by dialing the correctness of some of the layers to 100%, doesn't mean that's how you should achieve it and that there aren't cheaper ways.
The only way I was able to grok programming was through Racket.

As kfreds correctly states, there are important questions other than who the OEM for a mainboard is. With the exception of notebooks (where OEM specific components like the embedded controller require a fair bit of work that can be transferred from one device to the next), I'd even say that the OEM is among the least interesting bits about a mainboard on the technology side.

However, if the OEM supports the coreboot port (e.g. by providing schematics and generally answering questions that come up) that's very helpful.

So, question to kfreds: how was the cooperation with Supermicro? Are they aware of your effort, were they helpful?

(disclosure: doing coreboot development for 12 years now, some of that professionally, now for Google's Chrome OS devices)

I live in Idaho. A couple years ago a boy and his dog where walking in the foothills near their house and ran into one. It killed the dog and nearly killed the kid. These are a terrible idea. They should especially never be placed so close to a city like it was in this case.
Lynching has always been driven by people reacting to what they believe was a credible threat, that law enforcement has failed to protect them from.

In the historic case, that 'credible threat' was 'race mixing', uppity ______s, jews that were too well off for their own good, etc.

When you let the most violent members of a small town community unilaterally decide what is, and what is not a credible threat, that is exactly what you will get.
That's the kind of logic used to justify lynchings. We have a legal system that enforces a certain burden of proof, that takes place in a courtroom where strict procedure is enforced by an ostensibly impartial judge, and evidence is weighed by an impartial jury. The system is carefully set up to balance the rights of the accused against the interests of the community. It may not work all the time, but it exists for a very good reason, and mob justice is no substitute.
Ok - haven't read the article, paywall, etc - but from what I've heard elsewhere, the tagline should be "...are the Feds"

Maybe that's more a joke than anything - but it wouldn't surprise me to find out that the Fed to Blackhat ratio wasn't something huge, and those actual BH attendees were either other researchers who go to "be cool" (or legitimately present research), or were major "n00bs" who don't understand what they are trying to get into, and will likely end up in the Feds hands in short order.

Or maybe all of them are faking it?

It just seems like - if you were a real BH worth your salt - a conference of any sort where you effectively are advertising your creds would be avoided. If you went at all, you'd want to do it under the radar. At which point you might as well go to DefCon, Hope or something.

Its an interesting scene nonetheless - which maybe is why there are any attendees at all; maybe the whole thing is just one giant form of cosplay LARP - and the people who participate are really BH's and LEO's? Like some kind of weird meta-thing going on...?

I think this is different. Jury nullification is about a lawbreaker not being punished. Vigilantiism is about an innocent person (innocent until proven guilty through judicial process) being punished. If we as a society have committed to the idea that option a is better than option b, then they seem more like opposites.
Given what you're going for, Javascript will be your most important friend, followed by css even if you aren't a designer, as well as html. It's worth also learning git. Still, you'll have to learn more the concepts, and even then you have to roll with the punches. We're all re-learning constantly.

Good luck!
It’s arguably the best pure functional language implementation. So if you think functional programming is a good thing, then yes it’s worth learning. The worst part about Haskell is you realise how lacklustre functional programming is in every other hybrid language. The lisps probably come closest in capturing a similar feel.

> Sure you can get to a better place and you should try to do so. What I am saying is that it’s very hard and that it’s not your personal failing if you don’t succeed.

Agreed, of course. I'd go so far as to so this is a prerequisite for doing anything difficult. But I interpreted the following quote as a considerably more hopeless outlook:

> As an individual you almost have no chance to escape unless you put in a lot of effort to get better information and even then it's hard considering how much misinformation is being put out.

It doesn't take Herculean effort to fix these habits, it just takes a sustained attempt to change your habits, without even pushing that hard. (and of course, there are the particularly-susceptible for whom even sustained effort won't work).

My pushback was against the sentiment often expressed here that there's no hope at an individual level, but it sounds from your second comment like you don't agree with that either.

They're measuring jobs created in the same commuting area as high-tech jobs. This seems like a poor metric: operations like Google put the high-tech jobs in a few places and the low-tech jobs in other places. There's no reason to co-locate them, so they can each be where the labor with the right skills is available.

They don't specify whether gig jobs (like Uber drivers) are included. At any rate, these are rarely colocated with the high-tech jobs so they wouldn't count for much in their methodology anyway.

"A utility-first CSS framework for rapidly building custom designs."

It's an excellent description in of it's own, but if I were to attempt to put it in other terms, it allows you to compose css components and classes out of other smaller, essentially one liner css classes, while maintaining a consistent styling and spacing across the different utilities, which you define up front using the config but also comes with good defaults out of the box.

It is excellent and now my preferred method for hacking up a new site. It also helps you think about your design system overall so now I find myself paying attention to things up front I would normally wouldn't and it ends up saving me time in the long run. It also pairs really well with the excellent Refactoring UI book.

That's a lot of trust in the merchant services. "What transaction?", then if all you had was a transaction ID what do you do?

Also, to process refunds you need to have payment details.

In your second case only store the details if people explicitly want you to. You can do repeat customer discounts by sending vouchers for a later order with the present order confirmation. (You can't restrict discounts to those who give up their PII if I'm reading things right.)

Sure, there's no accounting for preferences. But for many, a voice call taking the place of every text conversation is a lot _more_ intrusive (albeit in a time-limited, focused way). Shooting off a couple of texts to nail down the details of when you're meeting up for prearranged plans is convenient for calls because it doesn't have to be fully synchronous: send the text, and if the other person responds when you're free, then you can have a synchronous conversation. There's no real analogue with phone conversations other than playing phone tag, which seems like a lot more mental load.
