  • Mh, ‘0’ is a nonempty string, so !‘0’ returns false. Then of course !(!‘0’) would return true. I’d absolutely expect this, Python does the same.

    And the second thing is just JavaScript’s type coercion shenanigans. In Python

    bool('0') # returns True because of nonempty string
    bool(int('0')) # returns False because 0 == False
    

    Knowing that JavaScript does a lot of implicit type conversions, stuff like that doesn’t strike me as very surprising.






  • Whoever wrote this has an extremely outdated technical understanding of renewables and energy storage… or wants to push this outdated understanding out of an economic interest/agenda.

    Yes, a stable AC grid needs inertia, which was historically only provided by the generators in gas, coal and nuclear power plants. Yes, inverter-connected systems like batteries and PV plants don’t provide inertia naturally. But there are control algorithms out there which would enable these systems to provide inertia just as well… And they could be going into large-scale rollout at least on new batteries and wind power plants within months if it was required by grid codes or incentivized by a market.

    I agree that, whatever exactly happened initially, led to a disconnect of the mostly photovoltaic generation in Spain (not yet outfitted with such synthetic inertia algorithms) and the central European grid where more natural inertia was available. The high local PV surplus no longer exported to Europe led to an enormous increase in the grid frequency. The PV plants disconnected which led to a just as quick decrease of frequency and an automatic disconnect of loads - boom, the grid is dead. So far, their analysis was also what I presented to my students on Tuesday. But drawing the conclusion that renewables are bad just reveals either incompetence or an insidious agenda.



  • I’m not an egoist anarchist, but the other answer to your question is wrong and I don’t want it to be standing there without correction. Egoism in an anarchist context goes back to “The Ego and His own” by Max Stirner, a German philosopher. He was not an anarchist, but has been and is still very influential on the movement.

    Here’s his works on the anarchist library: https://theanarchistlibrary.org/category/author/max-stirner

    I haven’t read it myself yet, but read some short summaries. Afaik he wants everyone to acknowledge that we’re basically working in our own self-interest all of the time BUT that this requires cooperation and that helping others without immediate material benefit can be part of our self-interest, e.g. because it makes us feel good or because it builds relationships that might be beneficial later.

    Uff… Red Scare war wohl damals schon erfolgreich.

    Ich meinte aber tatsächlich eine Quelle dafür, dass Ebert das Mist fand. Ich habe dann aber den Wikipedia-Artikel zum 9.11.1918 durchgelesen. Schwer, dabei nicht zu kotzen.

    Ist halt totaler Käse, weil die deutschen Kommunisten keine Bolschewisten waren. Liebknecht und Luxemburg hatten andere Vorstellungen, die viel mehr an der ursprünglichen SPD orientiert waren.

    Hast du irgendwelche empfehlenswerten Texte von den beiden, außer den “organisatorischen Fragen zur russischen Sozialdemokratie” und dem unfertigen Text zur Oktoberrevolution aus dem Gefängnis?
