  • Fan blades are basically spinning wings or airfoils.

    Depending on their design or how expensive they are, they may rely on pushing air rather than aerodynamic effects at low speeds, and they’re always optimized for a specific rpm.

    As it speeds up, the aerodynamic flow takes over, with the rotors creating a pressure differential that pulls air through.

    As it gets faster and faster, eventually, that pressure differential reaches the next rotor and the entire thing stops being as effective because now the the second rotor is stalled out. (Only they’re all stalled out because any given rotor is both leading and trailing.)

    Said another way, each rotor is passing through the wake of the previous rotor and not pushing more air because the air is already moving with the wing.




  • Yes.

    All the time.

    I’m there at least once a week and I usually chat with the librarians for recommendations and to catch up with a few staff I’ve gotten to know.

    They also have around 30 different clubs going on weekly, one of which I occasionally lead (teaching people the basics of 3d printing and design,) and that’s not including the dozens of book clubs they got, or the movie clubs.

    And then there’s the larger events like “art days” or visiting cultural groups. The drag story hour, the princess story hour; the story hour for adults.

    The major alternatives to prom and homecoming dances.

    The tabletop gaming sessions.

    Bingo night. Gin, hearts, spades and bridge night.

    Most libraries will have something for everyone, even the poorly funded Hicksville ones where the churches likes to sell itself as an alternative 3rd space.


  • Church is not a great place for third places- unless you happen to be like all the others at that particular church.

    No church will actually accept you unless you’re the same as them. The “sameness” doesn’t have to be about race or orientation or accepting that.

    They might be totally willing to let you in the front door, but unless you conform, that won’t be for long.

    Libraries are a much, much better 3rd place, and they don’t try to ram theology down your throat to use it.






  • eh. I wouldn’t say that. Sure there’s some awful games. But by proportion, there’s only a few AAA titles each year, and the vast majority of them are at best meh. The plot is trite, the mechanics pro forma.

    The real creativity is in the indie world. if you consider it by dollars, indie games tend to win out. (lets exclude all the cheap mobile games that… basically are there to sucker you into micro transactions…)



  • well, technically not ‘food’, but water is pretty much a superfood in that drinking sufficient amounts will improve virtually every aspect of people’s lives. (unless you happen to live somewhere with Republicanium Pipes™️)

    But yeah. It always cracked me up when people point to berries (those Acai stuff, for example) saying “super food” because they’re “high in good stuff”. Like. Every other damn berry.) (and those greenhouse strawberries we get in winter? Much lower carbon emissions.)



  • In the street with many cameras and witnesses, pretty high chance.

    lets say, hypothetically some rando walks up and caps you, exactly like Luigi did the CEO. it took, probably, millions, or hundreds of thousands of dollars in terms of cop-hours, and a lot of that is straight up overtime. then there’s things like draining the pond in central park, or whatever. the divers. the chasing down faulty leads.

    and none of that was actually useful.

    what got him in the end was the media campaign pushing his face (well. supposedly his face. there’s holes in that story.) in front of everyone. And the only reason it had massive media campaign was because Luigi whacked some asshole who was a real prick, even by Health Care CEO standards, and that made it news.

    they’re actually more likely to figure out the other, because there’s going to be a handful of people who have access to your place. Whoever has keys becomes suspect. Or whoever was in the place. at the very least, no forced entry means you knew the person, at least enough to open the door for them. (Pizza guy?) that’s more than they had on Luigi until the McDonalds lady called it in.

    (Seriously. Unless they have a continuous footage of him, spliced together from one camera to the next, never leaving it, then they matched Luigi’s face to a pair of eyebrows on grainy video. Sure they might have DNA or something more now, but those photos were a joke. as they say. “he fit a description”. a blurry, pixelated description.)
