#FuckAndroid its time for #MobileLinux
google has made it clear time and time again that they are not intrested in android being driven by the community.
android and aosp are so far apart from each other nowadays that it is difficult to call android "open source"

Magnetic-Suspension Hoverboard is Only 11 Years Late
Anyone who saw Back to the Future II was disappointed when 2015 rolled around with nary a hoverboard in sight. There have been various attempts to fake it, but none of them quite have the feel of floating about wherever you’d like to go that the movie conveys. The little-known YouTuber [Colin Furze] has a new take on the idea: use magnets. Really big magnets.
If you’re one of [Colin]’s handful of subscribers, then you probably saw his magnetic-suspension bike. We passed on that one, but we couldn’t resist the urge to cover the hoverboard version, regardless of how popular [Colin] might be on YouTube. It’s actually stupidly simple: the suspension is provided by the repulsive force between alarmingly large neodymium magnets. In this case, two are on the base plate that holds the skateboard ‘trucks’, and two are on the wooden ‘deck’ that [Colin] rides upon.
Of course magnetic repulsion is a very unstable equilibrium, so [Colin] had to reduce the degrees of freedom. In his first test, that was with a pair of rods and linear bearings. That way the deck could only move in the z-axis, providing the sensation of hovering without allowing the deck to slide off its magnetic perch. Unfortunately those pins transferred too much vibration from the ground into the deck, ruining the illusion of floating on air.
After realizing that he’d never be able to ollie (jump) this massive beast of a skateboard, [Colin] decides he might as well use a longboard instead. Longboards, as the name implies, are long skateboards, and are for transportation, not tricks. The longboard gets the same massive magnets, but after a couple of iterations to find a smoother solution — including a neat but unsuccessful tensegrity-inspired version — ends up with a pair of loosely-fitted pins once again, though relocated to the rear of the board. From the rider’s perspective, it looks exactly like a hoverboard, since you can’t see underneath from that angle. According to [Colin], it feels like a hoverboard, too.
The only way to do better would be with eddy currents over copper, or superconductors over a magnetic track, but both of those methods limit you to very specific locations. This might be a bit of a fakeout, but its one with a degree of freedom. One, to be specific. You have to admit, it’s still less of a fake than the handle-less Segway we got in 2015, at least.

@exador23 I i didn't know that you worked on either of those!

@evan what part? lol.

@BathysphereHat this one gets it

Gli LLM sono una forza opposta ai social media?
Secondo un'opinione controcorrente, le loro risposte sui temi importanti seguirebbero il consenso degli esperti.

Really happy for Paul Thomas Anderson. He should have won that Best Picture and Best Director Oscar many times over before finally getting it tonight.
Full disclosure: I worked on the Punch Drunk Love soundtrack, and while we were recording Fiona Apple's 2nd record, he was filming Magnolia and dating Fiona. He's a good guy.

@evan None of the above... yet
