I don't agree. Lithium and Copper are mined and given electrification scenarios there is a projected supply deficit: https://www.iea.org/reports/global-critical-minerals-outlook...

Those prices are outdated now since practically all metals are surging.

There has indeed been great growth in battery capacity but it's as I said nowhere near able to supply a country like Sweden during the winter. It is off by orders of magnitude. We need 5TWh for that. It is not going to happen any time soon.

I understand California is different. Still, one would need to do these risk scenario calculations. Have they been made?

I know California has rotating blackouts already as it is. I really don't have any idea how people find that acceptable. If it happened in Sweden the government would be replaced on the day. It would be a real disaster.

I will be a bigger believer if a state like California can actually show its possible.

For sure I hope technology improves but the current ideas of solar+battery are simply highly unlikely.

The reason is that California has made their grid extremely vulnerable. The grid already heavily overproduces solar so it is reasonable to have negative prices. There is no sink available.

This is indeed nice for a well-to-do home. But there is a tragedy of the commons issue here.

The grid needs to be up 24/7. And while peak usage is just that, the grid capacity still needs to support peak usage.

This can theoretically be done using batteries but not for an extended amount of time. To say we can have batteries for 2 weeks of normal consumption is highly improbable.

The metals do build those batteries do not exist. Or put in a worse way, the mines do not exist.

An off the cuff calculation of costs and the massive amount of batteries required in the context of Sweden can be found (you need to translate) here: https://www.tn.se/naringsliv/40181/utrakning-60-globen-batte...

In other words, 60 full scale Globen arenas of batteries to replace current Swedish nuclear production.

So for small houses these investments can make sense currently. But from a larger perspective it's not that interesting.

The world is complex... It is a fact that Chavez and Maduro have completely ruined Venezuela.

That doesn't mean things can't get worse.

I pray the majority of Venezuelans really have had enough of socialist dictatorships and can find a way to govern themselves. The US should not govern Venezuela - but neither should Maduro or his cronies.

It was unavoidable and inevitable.

Still it saddens me that we will be sitting here in a years time and discuss our experiences of being fed ads served as "objective information".

Today if I ask: "should I buy a store product or just use raw material X?" , gpt and others will gladly say you might as well just use the raw product.

Pretty sure that will change very quickly.

Great news. Lets hope this is just the start.

The whole of Europe needs to get on with energy security and Britain can and should be a leader here, next to Netherlands, Sweden and France.

Interesting take. I agree with you mostly but regarding "community" I am more thinking of the side effects there in terms of _other_ people developing interesting libraries etc.

I don't know if AI can change that but when using python, there is a feeling that there is an awesome quality library for just about anything.

I like the ML languages, and as many others I spent a lot of time with F#.

I would love to spend more time but even though Microsoft gives it plenty of support (nowhere near as much as C#), the community is just too small (and seems to have gotten smaller).

Looking at https://www.tiobe.com/tiobe-index/ numbers fall off pretty quickly from the top 5-7.

Guessing this is the same for OCaml, even if the language as such is nice.

Out of all thousands of products, goods and services you will find plenty that track the official number "fairly well" out of of pure chance.

I fail to see any significance of this one chart.

Partially agree. It also seems like a desperate way to connect themselves to "AI" and the hype.

I think this says more about the state of modern physics than anything else. Sad.

Given the result, it seems 125k was a bit too high since they got so many submissions so easily.

The market sets the price, regardless of what we personally think is "fair".

I have some experience. Variants of regularization are a must. There are just too few samples and too much noise per sample.

In a related problem, covariance matrix estimation, variants of shrinkage is popular. The most straight forward one being Linear Shrinkage (Ledoit, Wolf).

Excepting neural nets, I think most people doing regression simply use linear regression with above type touches based on the domain.

Particularly in finance you fool yourself too much with more complex models.

Looking at the details provided by dailywire it's perfectly understandable why these people were arrested.

Had it been my workplace I would have wished for the same thing.

It's really ingenious to invent these avatars and make sure everyone has one and associate it with personality, fortune and romantic interests.

It sparks discussion, and gives people something to talk about right off the bat.

I have dated many girls who asked for my starsign (even that name! Marketing) and generally it's always just a fun conversation.

I've never had anyone suggest something ill or enacted violence due to astrology.

Of course I make sure to state that I don't really believe in it - but it's really harmless as far as I can see.

It's to the point that it's embarrassing to use in a professional setting.

You are sharing your screen and suddenly you access the stupid "news" menu, popping up with tabloid and perhaps the weather at best.

I try my best to use this software and disable what I can, but after an update to the OS or Edge you have to reconfigure stuff, and suddenly it has added back some horrible defaults.

Okay, it's "free" I guess.

Change the title name to be more approptiate. This is about private debt, not total debt.

"Why Northern Europe is so indebted" sounds like clickbait...

I don't get why I need this rather than just a plain container/dockerfile. That is how I work today and that is my "devcontainer", no separate markup needed.

Did I read too sloppily or did they simply not discuss actual availability, that is supply, of metals needed?

Was not my intention to misrepresent that. Absolutely true that it has declined in total over that time period.

I never made the claim you state either. The failure is the re-introduction now taking place.

Amid the energy crisis in Europe, and a looming shut down of the last nuclear plants in Germany in April 2023 and declining gas input; coal has been revived as the baseload power in Germany.

In the last months of 2022, about a third of power production came from coal. In 2006, about a third instead came from nuclear plants.

Officially coal is supposed to be phased out by 2030.

You do realize that central banks decide the time value of money by setting interest rates?

This is the central issue causing the system to behave erratically.

The irony of it all: the only place for socialism in our economies is the monetary system. No surprise it doesn't work well.

Still does not help when the wind simply is not blowing. You can't have an energy system dominated by intermittent sources.

Doesn't seem to be a difference. UK just has better access to gas, for now I presume.

Without a baseload power source a modern economy just can't function. That is why intermittent sources like wind and solar must be a minority of the energy supply.

In Germany they don't have access to hydro and have chosen to dispense with their nuclear capacity. That leaves gas. Without Russia that is becoming hard and expensive. That leaves coal. Germany had enormous deposits of coal.

Thanks. Then it's essentially the same situation. I imagined UK might be more fortunate due to being an island.

But then wind power can only be part of a mix of energy sources, with a strong supply of baseload power backing it.

The UK seems to have a very interesting situation. We also have a proposal for curtailment in Sweden for wind power producers, but for a different reason.

In the UK, curtailment seems needed due to power transfer capacity issues.

In Sweden it is purely due to grid stability reasons. As wind does not work as a baseload power source this becomes problematic as too much wind power generation can then negatively affect profitability for nuclear and hydro which are baseload power sources.

I would be interested to see how stable wind power production is across all hours and throughout the year in the UK. I imagine it's better than here, but is it good enough to support an industrial nation?

Did you look at the situation in Germany? The foremost country on renewables...

And brown coal.

All depends but mining operations are complex to setup, not only operationally but legally.

When doing this, you get the know-how and research on how to do it properly and efficiently.

Plus, we want to - to the extent possible - rely more on metals than oil, so seems logical enough.

Very important to start mining these to get away from dependence on questionable activities in China and Kongo.

We just have to hope that the "greens" don't stand in the way as they usually do.

Exactly. And not just in the US, we have had significant indications that the government in Sweden "collaborated" with social media prior to the election.

They lost anyway, but we have no idea what kind of effect they had and what stories were suppressed.
