My family learned thirty years ago never to utter the words 'Doctor Who' in my presence.

Ive always kinda been obsessed with truth. Its not a good obsession. outside of that I can be a bit of dilettante sometimes delving deeply but for a period and you can't really stay at depth if you keep moving around as in any field things change a lot. There were times I was into scifi/fantasy/reading and technology and its not like Im not anymore but its more like its not that unusual anymore compared to when I was young.
Currently it’s buying stupid but vaguely useful things.
I spent $50 on a SDR radio that can listen to a very wide spectrum of stuff. Also got a cheap pair of GMRS radios and got hooked onto the local repeater tower for about a 50 mile radius of communication.
A friend had a gas coming from their oven on occasion so I got a sensor for about $70 to try to fix it (and did so successfully)
I have more flashlights than any one man needs, but they do come in useful.
I just got a lock pick set and a practice lock. Probably never use any vague skill I’d develop, but if it saves me calling one locksmith, one time, it’ll have paid for itself.
A good pair of binoculars is just nice to have.
Tools of any sort.
Non-stupid prepper stuff should some crazy shit go down. Water purification, solar systems, weapons.
I’d like to try one of the mesh networks, but have more pressing hobby-crap to pursue.
It feels a little generic, but video games. I’ve been playing them since my dad got a Gamecube around launch, and I’ve been reading about them since ~2011 when I discovered Steam and graphics cards. I learned within a year of watching the store that sales on Steam generally update Tuesdays and Thursdays, and I’ve checked what goes on sale for at least 90% of the Tuesdays and Thursdays since then.
I used to read a lot of IGN, then Kotaku, then r/games to keep up on everything. Now I mostly listen to a couple gaming podcasts (Minnmaxx and Triple Click) and that covers enough big and small games for me.
I like to say that I have a near encyclopedic knowledge of gaming from about 2007 onward, meaning for a given game I can give you a general idea of the genre, reception, notable influence on or from the industry, and I can usually recall at least 5 seconds of gameplay. The most exciting thing for me in conversation is when someone brings up a game I haven’t heard of or know nothing about.
License plates.
Art and science in all forms, which covers a lot. Daily it's mostly gaming, music, movies/shows and science videos and articles.
I am one of the developers for Project Rubi-Ka, a server emulator/private server for the classic sci-fi MMORPG, Anarchy Online.
AO is now nearly 25 years old and no longer has any developers at the company that released it, but it is still running.
I have written over 2,000,000 lines of server emulator code for AO. I am now probably one of the world's foremost experts in how the game works.
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
Rock and stone.
For Karl!
My special interest is everything. Well, everything except getting my ADHD treated.
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 it's Single Input and Single Output (SISO), you do the Laplace transform of the signal L{y(t)}=Y(s), obtain the Laplace transform of the input L{x(t)}=X(s), and then obtain the transfer function of the system: H(s)=Y(s)/X(s), you must be aware 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 are filters and other numerical approximations for a reverse convolution.
Thanks, I haven't touched DiffEqs properly for a while
For many years now, unions. It started when I became a union organizer in 2021. I love the rich history of the labor movement, the unending struggle against capitalist forces, the drama, the conferences, all of it. I'm going to Labor Notes this year as a rep for my local!
I tend to have distinct phases of special interests, and I still find the topics interesting after they fade. The earliest I can remember is tractors, then space, then castles and knights, then guns, then ww1, then ww2, then computers and programming. Now it's unions
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.
I know it's not for everyone, but I play online weekly-biweekly and it's great.
Very excited that the Draw Steel VTT just dropped
HISTORY AND HUMAN EXPERIENCE!!
And with history i mean EVERYTHING Music, philosophy, archetecture, theologie, society, musical theory, design, aso!!
EVERY ASPECT OF LIFE JUST IS SO BEAUTIFUL!!
Currently on developing a mod (well development is on a hold because so many things happening that keep me buissy so there was no update since last august sob crying) for europa universalis 4 that expands on religions! So many interesting proto-protestant groups! The evolution of christianity really is interesting!
You sound a lot like me friend
For the past several years I’ve been slowly teaching myself audio production and engineering. I worked as a professional musician for decades but never bothered to learn that side of the craft. So once in a while I’ll go down YouTube rabbit holes, watching tutorials on, say, creative uses of EQ and/or compression, or an analysis of the mix of a well-known song, or bouncing ideas and feedback off a small group of friends. Then I try to apply that to the songs that I’m working on.
The results I’ve gotten from my learning approach are decent, but I’m always comparing my own work to that of other established recording artists, and I have a lot yet to learn.
It’s a shitload of fun too.
Mapping!
Presently I'm using aerial photography to produce a map of local cycle ways and walkways.
Most things animated. If I'm watching any type of television or movies, there's a very high chance it's animated with a higher likelihood of being a cartoon. I don't watch as much yt storytime animators, but at one point I did watch at least Dan Plan ( I think that was their name ).
But I also have a special interest that really leans into that: anthropomorphic animals. A ton of the cartoons I watched growing up contained anthro animals and now I am known to occasionally search specifically for anthro animal/furry content for new games to look at or shows/movies to check out. Biggest reason I got into BEASTARS.
This might be a stretch but my mind dredged up memories of the first two American Tail movies recently. Are/were you a fan? It sounds up your alley based on your comment here.
My family had the second movie on VHS, so yes. I don't have either on DVD, which I should, but my brother currently has a VHS copy. I don't care if people say the second wasn't as good as the first because I love them both for different reasons, but I do love them.
I'm also, to a lesser extent, a fan of the Land Before Time series, which you'd never get me to admit IRL, and Secret of NIHM. Classic Don Bluth Entertainment films are some of my favorite classic animated films in general.
I have Secret of NIHM on DVD and maybe a year or so ago on a whim picked up a box set of all LBT films mainly for the early films since at some point the later films drop the whole prehistoric talk thing they did in the early films. Using "sun" instead of "sky fire" and such, which takes away a little bit of the charm.
Clouds!
And other weather phenomena, of course.
I just think they're fantastic and they change so often and tell us so much
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.
Most things in this world are 90% prep, 10% execution.
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).
Man I have so many interests. Playing basketball, lifting weights, learning Linux, learning how to self host, doing stand up comedy. Learning how to code a video game.
It seems to change by the week, but lately it's gone from linux to radios to electronic components/circuits
My hyperfixations jump around a lot though mostly it tends to stay in the STEM arena of things.
Currently I’m trying to design a language framework for building as low-level a language for reality as possible. Strangely (or not) I’ve touched very little in the way of linguistics and I’m wayy out of my depth in the field of logic and of all things category theory as well as philosophy because holy shit it’s kind of amazing we can communicate anything at all lol
In addition to that (and somewhat tangentially related) I’ve also been diving into the science of spiking neural nets and neuroanatomy in an effort to create an extensible self-supervised net I could then copy train to do a variety of tasks for me. Like the previous fixation, I am also very out of my depth in this project (also there are a lot more knowledgeable and well funded people who will almost certainly beat me to the punch), but even if I fail it’s already been a fascinating journey. Oh and I greatly dislike python so I’m basically reinventing the wheel multiple times in rust so that likely doesnt help my progress lol
Modernist literature between end of WW2 and the start of postmodernism, especially British, Irish, French and Italian
Making music. I play several instruments, some in perhaps an unconventional way.
I’ve got a bunch of instruments that I have no idea how to play, but that its fun to own. I have a guitar tuned to open E so my toddlers can bang on it. It’ll get destroyed someday but playable but crap sounding guitars are about $50 last time I looked (and a far sight better than literal toys).
Ugh way too many. Water plants, machine vision municipal waste sorting, building waste recycling, air-glass thermal energy storage (no phase change, ambient pressure, air as the working fluid), seabed warfare, and the role of geography on political violence (ornery hillfolk through the ages)
Right now it's biochem/microbiology. Found an entire lecture series on the bay and have almost completed it. Current lecture is on codons/anti-codons, all of them are 3 base pairs with Uracil/Thymine (resp.), Cytosine, Adenine or Guanine (TCAG which I like to remember as 3CAG; FREE PALESTINE)
Transport RNAs are specific to one of twenty amino acids by the anti-codon on it's base. The tRNA attach to their amino acid and slot into the ribosome in accordance to the codons on the messenger RNA it's translating. This creates a chain of amino acids that naturally fold as it's created because some aminos are polar and attach to each other. This is what is known as protein folding.
Like anal beads and some beads are magnetic, so when you pull them out some attach to each other creating loops and bends.
