  • Most money is not really created by central banks. It’s created by private banks when they make loans. They literally add a number to their assets, and to the borrowers liabilities - and the borrower can now go spend that new money.

    Central banks are supposed to try to regulate bank lending to try to stop the pyramid spiining out of control.

    Governments also take out loans though (by selling bills, gilts, bonds) - so they are also involved in money creation process, that money typically goes to pay public services and public servants.

    But the majority of money creation is typically private loans - and much of that goes ino property price bubbles , which does indeed benefit the rich.

    TLDR - The use of notation is poor - I’d call it sloppy. His post would be much better (to me) without the example.

    Most alarmingly he’s written an inequality as an equality, and he’s not really explaining the units / percentages at all. I think this type of thing is really unhelpful to people who struggle with maths and maths notation. It seems evident that the last reply’s author does struggle and the example is part of their confusion, it certainly didn’t help.

    It makes me think he doesn’t give a shit what he writes or about the audience. That makes me inclined to give no shits about it too. Either way this style of communication is all red flags to me - I guess thats why I avoid all this twittery in general.

    Anyway, I guess I care enough to type a few more shits . . . I’m sure i’ve already put in way more thought than the OOP . . . I think he should have written something that spells out a bit more what is going on , and used an inequality, like:

    • 100 - 100 x (10/100) != 90 + 90 x (10/100)
    • 100 - 100 x (10/100) > 90 + 90 x (10/100)

    Or:

    • 100 - 100 x (10/100) = 90
    • 90 + 90 x (10/100) = 99

    As others have pointed out, in some contexts (like price indices) people convert time series data into indexes where 1 unit is referenced to: 100*1/(nominal reference price)

    So for units defined as “percent of reference price”, we d can use the simple expressions:

    • 100 - 10 =90
    • 90 + 10=100 (edited my own slop)

    Some people might, also sloppily, refer to the 10 as a “percent change” as shorthand for the units. It is a percentage, but one should be clear percent of what.

    If the context is more specifically weighted price indices then it can get more complex, but commentators may simply by saying “up by 10%”, when it’s really a more complex index value movement where the weightings can change. This all makes financial data in particular very confusing to those who struggle with maths, which is bad and it’d be nice if these things were communicated in a way that makes it as easy as possible for them.






  • I think I’d say ‘I kept silent’ as more common or ‘I kept quiet’, probably an even more common phrase. ‘Kept’ would be slightly more ‘active’ than remained I think.

    But “remain” does some nice extra poetic work here; it foreshadows another usage of [narrator’s] “remains” - the corpse or ashes or whatever lifeless material is left after their death.



  • I’d go basic debian . Install flatpak and flathub to get any packages that are too far out of date or might get so. Any derivative or ubuntu derivative just sees like unnecessary extra dependencies to me.

    Debian gives i think a wider choice of desktop environment than any of the derivatives on install, but I think they’re all much of a muchness really. Most of the DEs have the “Click something, window opens” feature.

    I think it’s mostly due to the the way the “ring mains” are often wired in UK to basically cheapout of copper I think . . .

    The consumer unit/fusebox/gfci protects the whole ring mains wire from overheating or ground leakage - up to the socket - but that will likely be more current than any individual appliance would want to see maybe 20A or 32A or something. So it’s up to the appliance to protect itself (and its wiring from the plug) from overcurrent scearios per its own tolerances.


  • Rat pogo stick.

    Unfortunately rat consumers are notoriosly sensitive to the ‘not tested on animals’ logo, so is not as simple as attaching rat and observe.

    Standard practice is to tape a large potato to the top part and check it bounces properly.

    The datasheet should state the specific bounce characteristics to test against, but normally, it should bounce between 2o% and 40% of it’s length, when dropped from 40-50% of it’s length. I think the standard weight for the testing potato is 700 +/-20 grams. Again the datasheet might indicate a different range if it is specifically marketed towards a niche market like juveniles or the obese or something.
