@marzlberger @justine @alelab I can see this. I've just disabled the public disclosure of external messages. I mean: you can't see external instances' posts using the BSD Cafe server if you're not logged in. This because I've seen some bad contents (posts without CWs, porn, illegal stuff) being served by the BSD Cafe (not by BSD Cafe users) and publicly available. I'll make a public post about this.

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.

@geeknik this sound like a dystopian fiction. Don’t wanna believe it.

Have never, don't, will never understand why people.
No wonder advertising won everything.

@geeknik Yup. It was a honeypot. All this time.
And bombs will drop according to that location data some day.

@alienghic @annamam That's an oddly accurate description of this place.

@geeknik Having done the free labour of approving pokestops for them, I feel like they're overselling the quality of this data.

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