They're not represented, because those are build-time dependencies. Most users when they do pip install numpy or equivalent, just get the precompiled binaries and none of those get installed. And even if you compile it yourself, you still don't need those for running numpy.

It is sadly really inconsistent. The stdlib statistics has two separate functions, stdev for sample and pstdev for population. Numpy and pandas both have .std() with ddof (delta degrees of freedom) as a parameter, but numpy defaults to 0 (population) and pandas to 1 (sample).

Someone correct me if I'm completely wrong, but by default (i.e. precompiled wheels) numpy has 0 dependencies and pandas has 5, one of which is numpy. So not really "squillions" of dependencies.

It is surprisingly hard to find reliable figures. Best I could do was a global solar installation of 2-3 TW and global BESS of around 200 GW/500 GWh right now.

China is leading in both, but I'm more interested in local BESS and other storage deployments locally in northern Europe. I think for example Spain started getting more heavily involved only after their massive blackout. According to those links there is a very large overcapacity in battery production, but I don't see it reflected here. I'm sure it will happen at some point though.

I looked at tomorrow's (8th of October 2025) prices in Norway and Sweden. Northern Norway drops down to (negative!) -15 €/MWh at 17:45 while southern Sweden peaks at 190 €/MWh at the same time. So that's that for buying "from across the continent", let alone from your neighbors or even your own small country. I'm not sure that even the suggested reconductoring would help that much.

To answer ajross: I'm quite sure that the shutdown of Ringhals and Barsebäck in southern Sweden has had a much greater impact on their and likely southern Norway's prices as well than building for example 10 times the equivalent solar capacity in Spain. It is not even about losses, but just the grid capacity. Theoretically the prices in Nord Pool (from southern France and western Ireland to northern Norway and eastern Baltics) should be equal. As pointed out, in practice they vary wildly. And in principle it can get even worse. It would not be too unrealistic to have negative prices in northern Norway and rolling blackouts in southern Sweden at the same time. I'll leave it as an exercise to the reader how the latter can even happen when Sweden has enough capacity to meet its power demand at that time.

I don't think it will happen either, but I do think there is a bit of imbalance developing in the whole system right now.

For example a decade ago electricity prices in Nord Pool were relatively stable (and reasonable/lowish). Now it is quite common to either have 0 or even negative prices during summer and artificially set maximums in the autumn/winter. IIRC, the rules were that if the price hit 60% of the maximum, it had to be raised by 1000 €/MWh. It got to 4000 €/MWh (which is 4 € or $4.7/kWh) in 2022 and was supposed to be raised by another 1000, but it was decided not to do it, so I think it stands there right now. But in any case, this is a ridiculous price. As are the negative ones.

At some point of adaption everything becomes grid scale

Yes, but storage has been lagging behind and when it catches up is to be seen.

Right, but would not marginal cost approaching zero amplify this problem under the current market system (and without any other mitigations)? So not exactly causal, but making it from a small to a bigger issue.

This is not about grid balance, so I'm not sure what you mean here by curtailment.

It's about nobody making any money, so there will be no incentive to continue building solar.

It has become so incredibly cheap that in some parts of the world it has started eating itself, called solar cannibalization.

The corp is a subsidiary. It is irrelevant if and how long you worked there for, the parent company has the financial and legal control over all the subsidiaries. The foundation literally owns the corporation, no need for quotation marks. If they have not or do not exercise that control or interfere in the day-to-day life today, that does not mean they will not do it tomorrow or whenever it becomes necessary. When shit hits the fan all that matters is what's on the paper.

I can also say, that my hypothetical landlord has nothing to do with the place I have lived in for 10 years. So therefore they do not "own" it.

First of all, I'm not that young and naive to appeal to authority any more after having met too many so-called experts why have only succeeded by the "fake it til you make it" technique. So checking someones bio is unnecessary.

"The Mozilla Foundation will ultimately control the activities of the Mozilla Corporation and will retain its 100 percent ownership of the new subsidiary. Any profits made by the Mozilla Corporation will be invested back into the Mozilla project. There will be no shareholders, no stock options will be issued and no dividends will be paid. The Mozilla Corporation will not be floating on the stock market and it will be impossible for any company to take over or buy a stake in the subsidiary. The Mozilla Foundation will continue to own the Mozilla trademarks and other intellectual property and will license them to the Mozilla Corporation. The Foundation will also continue to govern the source code repository and control who is allowed to check in."

If this is wrong, please remove it from Wikipedia too, or add an explanation why this plan failed.

Also, if this is wrong, we cannot trust what anyone from Mozilla has to say, including you since they can say one thing and do another.

Also, if this is wrong, why are there consolidated financial statements of "MOZILLA FOUNDATION AND SUBSIDIARIES (Mozilla)" https://assets.mozilla.net/annualreport/2021/mozilla-fdn-202... According to the report, Mozilla foundation (and its subsidiaries) had a revenue of $600M in 2021. If the foundation has no control over the corporation, how can it include the revenue of the corp in its financial report? Is something fraudulent going on in Mozilla?

Exactly, I would even say the foundation has not only lots, but everything to do with Firefox. I don't understand how there are so many "ackshually" guys in this thread. It is all the same thing, Mozilla, and the separation is and has always been only a technicality, nothing more. It is exactly the same as saying The Walt Disney Company has nothing to do with Disney+.

Stronger bonds by definition are lower energy bonds. So you get energy out by making the total bond energy go lower or "releasing it".

Did you just take two random numbers from that paper without reading any of it?

Their black cotton shirt blocked >99% of both UVA and UVB and the white one roughly 90%.

I looked around a bit in "definitions.units" and there are actually energy densities in there for various fuel sources, including diesel.

  You have: 1 diesel
  You want: Wh/L
   1 diesel = 10103.465 Wh/L
Slightly different value than in Wikipedia, but close enough.

No need to complicate things with obscure units.

  You have: 40 MW/30% / (10722.2 W*hr/L)
  You want: L/hr
   40 MW/30% / (10722.2 W*hr/L) = 12435.259 L/hr

It is not a particularly good example. A better one would be

    a = 1
    def foo():
      x = a
      a = 2
    foo()

    > UnboundLocalError: local variable 'a' referenced before assignment
Basically a name cannot be both global and local inside the same function. Otherwise it would be a total mess.

"a = a" just means assign the value of local variable "a" to a local variable "a", so the error makes sense.

You have measured the apparent power (volt-amperes), not the active power (watts) that you pay for. There can be quite a big difference, especially at standby.
