  • The fact that you think the constant whining and blamecasting at nobody in particular constitutes a callout speaks volumes. And the fact that your first resort on being challenged is a barrage of insults speaks even more. Someone more intellectually minded might even use it as a jumping off point for some introspection, or see the parallel with US politics in general and foreign policy in particular - but, of course, that would risk recognizing the nose and rainbow hair as the reflection in the window pane that they are.

    Honk-honk, Buttons. Honk-honk.




  • …Here’s a thought exercise for you: The year is 2028, Trump is running for a third term, and the Dem ticket is… IDK, Newsom/Buttigieg or whatever, and the big thinkers of the DNC have come up with a foolproof plan to steal away MAGA voters: they will agree with exterminating trans people, but! BUT! will firmly, and I mean FIRMLY stand behind gay marriage. And you’re trying to explain that both of those choices are unacceptable to you, and in response are met with an avalanche of mockery because “sure, yeah, one side wants gay marriage banned, but they’re both the exact same amirite?

    Seriously, though, best of luck. Not to assume stuff about your situation, but getting out sooner rather than later sounds like a good move.


  • You may think that now, but I distinctly remember the then-prime minister of Estonia and current vice-president of the EC honouring a summit where the participants were carrying around a blow-up shark. Why a shark? Well, a random Russian tourist got killed in a shark attack some time earlier, and, well, dead Russian, ha-ha.

    It’s good to see the sentiment has receded somewhat, but it is concerning that it literally took the tables turning to get people to self-reflect.

    Essentially.

    A straightforward example would be an equation system: 2x+4y=10, 3x+5y=13. You could solve it manually, or you could call Cramer’s rule and plug the numbers into the formula:

    Ax+By=C
    Dx+Ey=F

    x=[CB/FE]/[AB/DE] = (CE-BF)/(AE-BD)=(10*5-4*13) / (2*5 - 3*4) = (50-52)/(10-12)=1,
    y=[AC/DF]/[AB/DE]=AF-CD / AE-BD = -4/-2=2

    Pure algo, no thinking required. Also note that you don’t strictly need x to get y and vice versa.

    In a more complex example: You’re making a program to draw something in 2D. You could implement mirroring, rotation, scaling etc…, or, you could declare each point (xy) a vector V=[X Y], implement matrices, and then V times [1 0/0 1] gives you V, [-1 0/0 1] gives you V mirrored on the Y axis, [1 0/0 -1] mirrors on the X axis, [j 0/0 j] scales it by j, [cosw -sinw/sinw cosw] rotates it by w… Makes life much easier.

    You know how you can write “5+5+5-4-4-4” as “35-34”, and then use it for weird shortcuts like “3*(5-4)”? Well, matrices make for relatively easy handling of certain systems of equations, letting you fiddle with the whole system at once instead of restating equations one by one.
