For people who are interested in the context, it was a student living at uni who moved home again during the COVID lockdowns. Once they’d lifted they came back to the flat to see this.
Fair enough, but did they use it? I always felt like focusing on statistics instead of random trig stuff for non stem people people would be more useful
Agreed, I use highschool level stats knowledge on a nearly daily basis, whereas the last time I did any trig was to follow along with a math video I was watching on YouTube. Trig/calc were mandatory, stats was not.
And stats really should be a mainline math class in high school. It comes up in so many places, and is far too often simplified away into a binary black & white choice.
Any time something happens that was predicted to be less than 50% likely, people lose their shit. For instance, when it unexpectedly rains or the wrong person wins an election.
But it’s not even being able to run the numbers or understanding statistical significance. It’s much more basic, just understanding that probabilities and uncertainty exist and are everywhere. My favorite example is when going to the doctor. They explain that whatever you have is probably X or Y, with a small chance of Z, but Y has been going around a lot and is easy to treat, so let’s try medication A for it. Then when that gets reported to friends and family afterwards, it’s “she said I have Y and I need A to fix it.”
Many modern compression schemes are more about signal processing than statistics , especially the lossy ones . IIRC 3blue1brown has a video on image compression if you want to learn about it in a visual way
Sticking with image compression, see Quite Okay Images. It treats each pixel as three numbers and expects mostly small changes. Recent pixels get hashed and can be referenced in a few bits. This is enough to compete with PNG filesizes, an order of magnitude faster, while handling each pixel exactly once.
though note than lossy formats , like JPEG which was used here , do use Fourier transforms , which are very intense trigonometry . IIRC PNG doesn’t use trigonometry either , though I’m not entirely sure yup PNG uses DEFLATE after some filtering , so no sine there I believe
exactly. those pesky children are easy to be radicalized; they have barely spent time learning anything at school, so they can’t really tell the bluff.
watch al jazeera for instance (a qatari MSM): hamas propaganda 24/7. qataris probably have stakes in this too by reselling arms, so it helps to keep the flame alive ( they would spend hours rebroadcasting the death of this ‘hero’ journalist in the battlefield, while in fact its lucrative that such people die to always have exclusive material to broadcast, its like a Marvel movie, but with real casualties ).
arms production is a lucrative business right now.
IDF destroyed Israeli homes (with Israelis inside) when Hamas raided them on Oct 7, and now they are indiscriminantly bombing Gaza, including where the hostages might be. I don’t see the logic at all. It seems like they don’t care about Palestinian OR Israeli civilians.
EDIT: I just stumbled upon this video, which shows Israeli police arresting a (black) Israeli soldier for trying to cross the street. It seems racist af. I really can’t figure out who they are protecting.
That’s what bothers me most: the incidence shows how Israeli military treats civilians in general but at least where I live, media doesn’t talk about the implications. The coverage is more critical than at the beginning of the war but they still refuse to call it a genocide.
Take a look at this. It’s a bunch of testimoniess from IDF soldiers about what happened when theie military ran similar operations in 2014. Looks like this is generally how the IDF operates.
It’s a military force full of conscripts it’s not a surprise they operate at an amateur level. These guys aren’t trained to rescue hostages they are only trained to shoot. There is a reason why most countries have gotten rid of conscription. Conscripted soldiers are nowhere near the level of a vetted and trained volunteer
I was trying to think of one. Lech Walesa came to mind, but it's doubtful. There was a Romanian president maybe 20 years ago that was a merchant ship officer, who often get f/l qualified (I did), but iirc, he flamed out.
