Two-stroke engines are that dirty. Cars have become that clean.
Using a wire, at least, makes it less stiff in torsion since a regular «metal tube» will have bending and shear stiffness. But then, it’s a tradeoff which could be worth it for some casual bikers!
Assuming Pidcock was in front on the actual finish line, his hub would have been about 5cm in front of the photo-finish line. That leaves about 3ms for him to finish the bike throw and return his hub behind Wouts hub. Seems like a stretch, but still a possibility :-)
Maybe you could also look at how deformed the wheel perimeter compared to a perfect ellipse to estimate the speed at different points?
EDIT: Or you could calculate whether it's humanly possible to move a bike a few centimeters forwards and back again in about 15ms, which I think the hypothetical bike throw must have been for Pidcock to be the actual winner?
The wheel perimeter idea I did suggest (cmd + f for the '40%' bit down the bottom of the article) but I think the tolerances are likely too small to do it properly. Would love someone to give it a go though.
oh-my-zsh tricks to blow your mind seems like a more appropriate title. I tried some of them in zsh, and they didn't work, because they assume you also installed oh-my-zsh.
Did the blog author actually un-blur the booking reference though? He states he tried to un-blur the barcode, was unsuccessful and then realized the booking reference was right there in the picture. Nothing about un-blurring it.
The original image was not blurred, he simply read off the plaintext booking reference. (After first trying and failing to scan the also unblurred bar code.)
