    During the pandemic I decided to get a barbell and start lifting at home. Fast forward a few years and I have a full on powerlifting rack and weights and completely changed my physique from “skinny runner” to “quite stout”. I’ve never felt or looked better in my entire life, and will yap uncontrollably if anyone mentions lifting within earshot

    I’d really like to play D&D.

    I used to play all the time with on again off again groups. Even when I wasn’t playing I was still immersed in the culture and constantly thinking of fun quest or character ideas. But, adulting gets in the way and I haven’t had a group to play with since COVID.

        That last one I mentioned during COVID was online, I didn’t have any problems meeting up that way. (Although it was a little tricky being 3 hours ahead of everyone on the West Coast.)

        Maybe I’ll put some real effort into finding groups who are willing to take in a poor stranger.

    Reefkeeping. Been into it for well over 25 years. Had several reef tanks over the years, with my largest being a 225 gallon that I had to break down last year (still pissed about that one).

    Too many. I collect special interests.

    The one that’s lasted the longest are:

    Filmmaking (specifically no/low budget filmmaking) with the premise being that regardless of tools, there are things that anyone can do to improve their product without a large budget. (ie. remembering to record tone for later editing. Planning your shoot for the proper time of day. Using reflectors even if you can’t afford lights. Blocking and Business, Shooting enough coverage for later editing, etc…) A large amount of quality in low budget films comes from taking the time to actually plan things out rather than just showing up with a camera and pointing it at volunteer actors.

    Things like proper blocking, shot planning, etc… are free. With digital cameras, film isn’t a commodity and there’s nothing stopping you from filming enough angles to give the video editor something to work with rather than just constant two-shots. Editing software itself is free.

    Point being, there is no excuse for lazy filmmaking, even if you don’t have access to expensive equipment. Planning trumps equipment 90% of the time.

    Okay…rant over.

      Same. Systems dynamics, mathematics, physics and metaphysics, etc. If people have tried to devise a system to explain everything, I’m interested in looking it over. I gotta know at least the basics of basically everything.

        I have a system dynamics question! Maybe you could point me in the right direction? If I have the system response to a step input, what is the simplist way to derive the transfer function? I’ve only ever learned how to use a system to do modeling, not how to reverse engineer the model.

          In a broad solution, you need to reverse the convolution of your system’s output.

          Assuming it’s a linear continuous system, and a Single Input and Single Output (SISO), you do the Laplace transform of the signal L{y(t)}=Y(s) and obtain the Laplace transform of the input L{x(t)}=X(s) and the transfer function of the system is H(s)=Y(s)/X(s), and the transfer function of the step is 1/s, therefore: H(s)=Y(s)/(1/s) => H(s)=sY(s), then you do the inverse Laplace transform: L-¹{H(s)}=L-¹{sY(s)}, which, depending on your system, may require partial fraction expansion. By the end you have h(t) (got a bit lazy here since y(t) is not known, but the step function is very well known).

          Of course I made a bunch of assumptions about your system, if your system has discrete steps, the Z transform is of interest, with its own caveats mind you. Then there a filters and other numerical approximations for a reverse convolution.

    The concept of change, i think? I was shamed for my special interests as a child so I’ve tricked myself into thinking I dont have one. I am surrounded by plants, I keep little brass figurines of butterflies, am constantly distro hopping, system swapping in tabletop games (and relentlessly trying to meaningfully maim and heal my characters). Hell, I’m getting a degree and working a job in two fields that I had no familiarity with as of last year.

    Art and science in all forms, which covers a lot. Daily it’s mostly gaming, music, movies/shows and science videos and articles.

    Lots of stuff. History in general; DIY stuff, mainly with recycling; uncommon programming languages (the stuff that tends to get less than 5% usage on SO developer surveys, such as Nim, Zig, Elixir, LISP, Vlang, FORTH); 3d modelling; astronomy; understanding different cultures (which is kinda an offshoot from history, I guess); drawing; games (video and board); writing fiction

    Coding. Why did it have to be coding? I’m not good at it. Everything I’ve read about it makes little sense. The tiny bit of coding I do get needs to be reinforced 1000 times over. So far I’ve made some triangles and my terminal spout some shit out. Nothing fancy. Yet in the back of my mind I’m gonna make a fucking video game one day and all this confusion and struggling will pay off.

      Are you wanting to code to make a game, or is it about coding itself?

      In the former case, there’s a number of good game engines that will let you bypass a lot of the low-level complexity. A lot of studios use these, so it’s not like you’re “cheating” to use these. Game modding might also be an option, if you just feel a need to make something.

      In the latter case, find a language you enjoy, and start small, find good guides, etc - sounds like you might be already doing some of this! But if a voice is whispering that a game is in order… might be worth grabbing Godot or something to play with anyway!

        More coding itself. I like figuring out the minutia of it. I settled on C for now. Maybe a switch to Zig once that settles down it’s development. I grabbed a few textbooks and read through them. I picked up linked lists and trees and the neat stuff you can to with that. The game is an end goal but building up the tool box is more of a skill I want to nourish now. The idea of writing my own engine is very intriguing too.

    I have 4, one for each decade of life

    1. Stargate SG1
    2. Anatomy, Physiology, Psychology, and Sociology of Sex
    3. Violence prevention, deescalation, and management in inpatient psychiatry (which became my career)
    4. Western Esoteric spiritual practices including Tarot, Astrology, Tasseography, Palmistry, and the myriad religious beliefs that they syncretistically evolved from
