  • I remember having a thought one day as a young kid while interacting with a DVD main menu (the kind that had clips from the movie playing in the background, and would play a specific clip depending on what menu you went in to).

    “This is basically how video games work, there’s a bunch of options you can choose from and depending on what you do it shows you something. Videogames are just DVD menus with way more options.”

    I grew up to not be a programmer.







  • During any point while writing these comments, did you ever stop and think: “maybe these students have a good relationship with the professor and knew how he would react to such a prank”?

    Like I’d get it if the guy said he was afraid of spiders and the following day someone put a fake spider on his desk. In that situation, they don’t know him well, the spider has a likelihood of being real, and a single person doing it without peer review can be iffy.

    But this is weeks later, everyone agreeing that the professor would find it funny, and doing something that could in no way be perceived as “real”.

    It’s like you didn’t even read my comment! /s

    Also, for the sake of clarifying my original point: it isn’t necessarily that the cookies were free, or that there were so many of them. OOP probably would’ve been just about as happy if the flight attendant overheard her and made a point to give her just a single pack- it’s the being acknowledged and having someone make a deliberate effort for you that gives the warm and fuzzies here.




  • I don’t know of any videos, but the concept seems to have gotten pretty popular in the last year or two. I’m in the 3D printing community, and there’s pretty frequently a “magic floating <whatever>” in the “popular” section.

    I assume the most difficult part would be determining what size magnets to use to achieve the desired float height. The rest should (in theory) be relatively simple; the magnets’ natural characteristics do all the hard work.


  • It is done entirely with magnets.

    There’s a few ways it can be arranged, but typically, there will be a large, powerful magnet in the base, a small magnet at the bottom of the floating object that is attracted to the big magnet (to keep the object upright), and a series of other magnets around the object that are repelled by the big magnet (to make it float).

    I’ve seen some that use a secondary “key” magnet on the base and object that is the opposite polarity of the base magnet, that forces the object to sit in a specific orientation. Otherwise, the object can just kind of freely spin/float, so long as the bottom magnet stays pointing down.
