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…

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 de…

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…

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 …

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 t…

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 w…

At some point of adaption everything becomes grid scale https://en.wikipedia.org/wiki/TV_pickup

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 f…

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. https://www.aalto.fi/en/news/rapid-growth-of-solar-pow…

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 li…

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" tech…

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 …

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…

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 nam…

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.

Thank you for the explanation. This looks to be correct, e.g. by changing 16807 to 16808 and using the sanitize options, the program can indeed terminate with SIGILL depending on t…

Those compilation options did not make the program abort for me nor am I getting any warnings (at least not with -Wall -Wextra), even when changing all longs to ints in the above c…
