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?

    Making video games. The shit people write here about game dev is ridiculous, they will even argue with you when they are completely wrong. In general people on the internet are way out of their lane when they talk about game dev.

      I sometimes get a feeling that the average person (that actually “made” a video game of any sort) and throws some semi-coherent but completely off the mark argument probably amounts to somebody who threw a few things together on rpgmaker or similar programs but never coded anything from scratch.

      Kind of like framework programmers trying to identify or explain any low level complexities that they are just barely aware of, if at all.

    Biochemistry — specifically protein structure. It’s so cool.

    My favourite protein is Green Fluorescent Protein (GFP). It was first extracted from a jellyfish, and it’s super useful in research. The middle bit is the bit responsible for the coloured glow, and the rest of it (the barrel type structure) is basically just to stop the emitted energy from being immediately absorbed by the solvent.

    If anyone wants me to nerd out more about proteins, hit me up.

    An enormous number of areas. The average — well, median, but assuming a vaguely-symmetric distribution, mean and median are close enough, and OP probably means median anyway — of any group has about half of the population knowing more than the average. This is going to mean that a randomly-chosen user probably has something like a 50% chance of knowing more than the average for any topic you could name.

    As of this writing, most people commenting are listing things that they could maybe call themselves subject matter experts in, like, top-sub-0.1% or something like that. That’s a much higher bar.

    There’s a lot of history nerds here, but I still probably know more about classical latin than most, though I’ve given up on that now. I had Roman literature as my major in university, before I got seriously ill and was forced to quit my life

        Someone else’s trash can. Alternatively, a hammer and nail typically work pretty well.

        More seriously, discharge slowly to as low as you can and dispose of per local regulations. I have disposal centers near me that take them.

          I just recycled some really big and spicy pillows at my recycling center. I used them for my drones, and they were pretty busted. (I kept them in a fireproof container outside) They wanted me to throw it in a barrel with other really messed up exposed wire pillows. It made me pretty nervous.

            Hahaha yeah general convention used to be just throw them all in a bin like nonrechargeable batteries. Train explosion in Houston a while back showed why that was a bad idea. That said if they’re all completely discharged, the hazard is much less because less stored energy AND the cathode is more stable (gives off less oxygen during decomposition). The former reduces internal short hazards/heat; the latter reduces energy and effluent release if they go off.

            The fireproof container isn’t a bad idea, but be careful of making a bomb. You want it to leak before burst just due to the large volume of effluent produced. Best practices are to reduce how much you store, keep long term batteries at ~25% SOC (less for disposal), and storing away from other flammables including other batteries.

      What charging pattern is best for the batteries?

      Is keeping the charge between 20% and 80% a good idea? Does it make sense to charge to 100% and to discharge completely from time to time?

        As close to 50% is best for longevity/cycle life, so the 20-80 rule is a good one. That said, devices Like smart phones with smarter battery management systems (BMS) benefit from relearning the battery voltage curve, so discharging/charging from 0-100 can be beneficial for accurate state of charge measurement.

        My favourite is probably the convoy t series. Kinda the spiritual successor of the fwaa line for me. You can get them pretty cheap, they have nice options and performance and are moddable. Also i really like aa/14500 lights. They are just so neat. If its about “full size” anf not “fun size” lights then probably one of hanks 21700 lights would be my pick. They are still comfortable to carry and also provide pretty nice sustainable performance and some gimmicks as well.

    Probably a decent amount of music stuff.

    I used to play piano at an ARCT level, and used to be pretty knowledgeable about theory and music history but I’ve forgotten a lot of it now. I haven’t practiced or studied since COVID hit so unfortunately a lot of it is gone now.

    The music that I listen to, I have basically an encyclopedic knowledge of. I know when they were born or when the band formed, when each of their albums came out, and generally know a lot of trivia about them.

    I collect records and have been learning a lot about record players and audio equipment over the last couple years. Not as good as an audio engineer but better than the average lemming I’d say.

    I used to do classical music composition pre-COVID. Again, probably not as good at it anymore, but I got quite good for a while. My music instructor at the time said I was the most impressive composer he ever taught. I’m still sorta riding that high from 2019. Very unfortunately, I had all that stored offline on a hard drive with no backup, and I’m sure you can guess what happened next. Since then I’ve been dissuaded from composing.

    I used to help teach and tutor music courses when I was in school. I was basically the music teacher’s pet, and this was at a music school. The music teacher in question happened to be the head of music at that school too (there were several music teachers at that school).

    A friend of mine, who was also into music and knew a lot of music students, once told me I was the only person he’s ever met that should’ve absolutely done a degree in music. This was at a time where he had a strong opinion that you should only go to school for a “real” degree that pays well afterwards. He’s since changed his opinion, but it was a big deal for him to say that to me at the time.

    The worst part of all this is my severe AuDHD meant that as soon as COVID hit and I paused music courses and lessons, I couldn’t get myself to continue. Now I live in a place too small for a piano so I can’t practice unless I visit my parents or in-laws, and I have different hyper-focuses now, instead of theory. I wish I could change my brain sometimes.

        Definitely a skill that decays quickly if you don’t practice it. I don’t do lockout calls so I always find I’m super rusty whenever I actually need to pick things for customers.

    Maybe coffee. I actually roasted an interesting batch yesterday that I’m looking forward to tasting 🙂


    Maybe guns too. I kinda lost interest in them years ago, so my knowledge/experience is pretty dated. I worked for a gun dealer for many years though. If you’re like a technical-brained nerd like me, guns can become a fascinating rabbit hole if you spend enough time around them. I knew almost nothing about them before getting that job.


    Also, maybe whisk(e)y. There’s so much to learn and explore in the world of whiskies. I used to enjoy touring distilleries when traveling. Some of them have such long, interesting history. And some of the newer distilleries get pretty creative.

    Fun fact: There’s an heirloom corn species that was saved from extinction by a bourbon distillery. It’s a very interesting bourbon! “Jimmy Red,” IIRC.

    Sadly, my pancreas suddenly decided that I had to stop partaking in one major part of that hobby: tasting. I miss it.

        Personally, it never interested me very much, so I couldn’t tell you much about it on a technical level. I remember thinking the decocker is kinda cool though lol.

        From the perspective of an FFL employee though: Those pretty much sold themselves. They’re one of those guns that people usually already know about when they show up to buy one. They’ve done their research, maybe already tried shooting one, and they’re excited to finally buy one of their own. IIRC, a decent portion of them tend to have military or police background.

        Those were among my favorite kinds of customers. I was usually able to learn some interesting things from them about the particular gun they’re buying.

        I wish I could recall more about the USP aside from the neat decocker, but I’ve been out of the business for like 7 years.

        Edit: I also remember that the .45 is an extra chonky boi.
