For me it’s probably speech therapy and everything pertaining to that. I’m yet to encounter someone on here who is one apart from me (in training).

What about you?

    Plumbing, since I’ve been a professional plumber in both North America and Europe. Not the most interesting knowledge base but alas, it is what it is. Other than that, Age of Empires II maybe?

    Anything remotely rural. It makes sense that Lemmy would be mostly city-dwellers, but I still manage to be surprised by the gap.

    honestly, i know a little about many things so i don’t really know. i guess uh, when it comes to skill, i can definitely draw better than the average lemmy user, and i know some theory as well.

  • I undoubtedly know more about fire than the average user here.

    I’m a circus performer with a decade of experience with fire performance/tech/safety. I teach other fire performers from beginners to professionals.

      • I started with fire spinning as a hobby and attending events. Eventually I got to manage a fire venue, received an invite to join a historic circus (Coney Island), and became a fire safety lead for a large fire retreat. The most important pillar for all this has been community.

        Unfortunately I had to flee the US (thanks Trump) so I’m taking things slow for the moment, but I have huge plans for the future

    Skydiving

    ~4500 jumps that included; night jumps, competition 4-way and 8-way, a couple of record jumps (I was on the a team that set state records in 3 different states back in the day) , Demos into various stadiums, air shows and a couple of NASCAR races.

    I might know a thing or two that the average Lemmy user has no idea about.

      Neat - paraglider here, but I know zero things about skydiving. It does seem to be common though, from talking to PG instructors, that skydivers learning PG tend to be very heavy handed with the controls. Just remember smooth and light if you ever try it out. :)

        Depending on the size of the canopy, there can be a fair amount of pressure required to pull a toggle. Tandem rigs, which have 500ft^2 mains are somewhat difficult to guide by one person. Most TM’s that I know require their passenger to help out. Not that they cannot be flown by one person, just that doing that 10 times a day wears a person out.

        My personal mains: PD Spectre 150 and 135, and Sharp Chuter (used for demo jumping) all had very different toggle pressures. The Sharp Chuter being the heaviest. It was also 90ft^2 larger (240ft^2) than my Spectre 150. My 135 had almost negligible toggle pressure. The smallest canopy I’ve ever jumped was a Velocity 103 and that thing has almost no toggle pressure what so ever. Plus with such high wing loading made it down right twitchy. Personally I was never one for ultra high wing loadings. Having 40mph approach speeds to landing was never appealing even when I was young.

        Also skydiving canopies are a LOT more square than a paraglider. While I could not explain the physics there, it seems to me that a thin wing would have lighter toggle pressures. Canopies that I’ve jumped that were more tapered seemed to have a lighter toggle pressure of equally sized non-tapered canopies. A paraglider canopy is extremely tapered compared to a skydiving chute.

        Also, don’t you folks have 6 risers? While there have been 6 riser skydiving rigs, they are very uncommon. So each riser requires a lot more pressure to pull… I’m assuming paraglides do riser turns and other maneuvers with them.

        There is a Paragliding club here where I live. Even met one when he landed at a local park when I was out walking. I currently have one kid in college and another going to be there in a couple of years, so it’s not going to be anytime soon, but I would love to try it out. I’d love to get back into the air. Skydiving is pretty much out, as I have a back injury that could be made really bad with a hard opening.

        To make a short story long… Yeah, I can see a skydiver being ham fisted with a paraglider. A jumper with a lot of experience with very high wing loading (over 2.0 to 1) might not, but me? Yeah, I’d probably ham it up for the first few hours. It would be interesting to learn just how much skydiving canopy experience would translate. I’m sure some would, but definitely not all.

    Cats, particularly kittens. I do a whole lot of fostering, particularly with very young and/or sick kittens. At this very moment, I have 16 fosters from 4 different litters.

    Graded Modal Dependent Type Theory, but that’s mostly because only “dozens of” people know it exists.

      What kind of grading do you give there? I guess the modal part is about the contexts for the type theory, but it has been some time I have looked into it.

        I think “graded” in the name is there in contrast to “quantitative” type theory, which doesn’t have modalities/quantities at the type-level.

        The “modal” is borrowed from modal logic. If you pick the correct semiring, you can recover linearity and affine-ity and the other substructural logic pieces.

        The quantitative semiring I’ve been working with is 0, 1, ?, n, +, *, which I think will let me use static analysis to do very precise non-strictness and precise/early resource tracking/release. (But, my progress is so slow, that if this were an academic project, I don’t think I’d be getting any more grant funding.)

    I am sure there are some cryptologists here, soo… Nothing? Anyway, I know a bit about how RSA is inferior to eliptic-curve based schemes, and how security can be such a diverse and complicated topic than simple two-party communications.

    My very specific niche in programming.

    If you ask me about some very common things, I have no clue. JavaScript? More like JavaShit amirite? But if someone can explain OCI layers, describe the boot process of a RISC-V device as it leads U-boot and a Linux kernel, and talk about performance optimisations in modern Python… Well, my team is looking for more developers and this combination of skills seems impossible to find.

        Look, you want the trade secrets then you put in the work, you’ve got to earn this kind of information. You come down and put in some work at the ranch and you’ll find your answers.

            That’s really nice of you thanks so much! Here is a fact for free… DA perps of course use coercive control to trap the victim. Cult leaders, terrorist cells, organised crime groups etc also use it but on a bigger, better resourced scale.
