My family learned thirty years ago never to utter the words ‘Doctor Who’ in my presence.
I have 4, one for each decade of life
- Stargate SG1
- Anatomy, Physiology, Psychology, and Sociology of Sex
- Violence prevention, deescalation, and management in inpatient psychiatry (which became my career)
- Western Esoteric spiritual practices including Tarot, Astrology, Tasseography, Palmistry, and the myriad religious beliefs that they syncretistically evolved from
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.
Art and science in all forms, which covers a lot. Daily it’s mostly gaming, music, movies/shows and science videos and articles.
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.
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.
Huh… I have definitely played Anarchy Online at some point in my life but only just remembering now after checking YouTube to find out what it actually is. I think I didn’t get very far at all…
The UI and aesthetic is so nostalgic. I miss games like this, except for the unnecessary complexity that got in the way of the game.
With all the extra processing power we have now, I wish we could see more games like this but polished.
Plane crashes.
Not in a morbid sense, but rather I like reading the NTSB reports about how the holes in the Swiss Cheese model line up. There are several Youtube channels that give detailed breakdowns on accidents that I like to watch as well.
Why?
It started when I was 19 when I saw the aftermath of United 232. My parents and I were driving through Sioux City IA about 4 hours after the crash. Fortunately, the highway was far enough away that only the larger parts of the plane could be seen. Bodies were not visible or had already been removed. That was 37 years ago and I still remember it like it was still happening.
I launched into learning everything I could about what happened to that airplane.
I had done the same thing with other accidents as well. Like many my age, I watch the Challenger accident live and Chernobyl happened that same year as well.
Add to that, in the 90’s I started skydiving. My home DZ flew two Beech 18’s. In one aircraft I experienced engine problems twice that elicited a bail out of all the jumpers. On both occasions the plane landed safely and put back into service after the engine was repaired, or replaced. The other Beech 18 I actually experienced a crash. It was fuel starvation on climb out and the pilot, who was the Drop Zone Owner, was flying. He put the plane down in a corn field off the end of the runway. All the jumpers except one got into the other Beech and jumped.
That just fed my curiosity. And yes, I still jumped after all of those occurrences. The crash actually happened first. I just tell it chronologically backward as it was the most serious of the incidents.
I also think that my studying of aviation accidents made me a better and safer skydiver. I was always thinking in terms in how things were lining up to allow bad things to happen. Not that I didn’t have close calls, I even wrote about one of them in a previous post, but I never experienced any major injuries in my 4500 jumps.
They aren’t making new ones anymore, but you might enjoy the back catalog of the “Black Box Down” podcast. I think it had about 12 seasons.
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
Excellent write up. Appreciate your time!
Fucking mood lmao
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
Optimizing the little farm I live on. It’s my side gig that I’m really passionate about. In season I have a very large vegetable garden, bees, sheep, goats, pigs, chickens, ducks and I recently got a big ass llama.
I would like to know more!
I finally have some land, and I’m trying to figure out how much I want to do, how soon, and in what order. (I’m working on my first vegetable garden here currently)
I made an edit to include what I have. You can DM if you want. Figuring out your goals and how they can correspond with a timeline you create is the first step.
Tell the chickens I said hello!
I’m not sure why no hellos for the others.
Tell them all hello!
Will do!
I’m between sprcial interests rn
Got tired of sharks?
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
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.
For another 2¢ from me, there are a lot of paid DMs out there if you can swing the bill.
After turning in my own DM cloak, I decided to jump into a beginner friendly PF2e game and met a ton of friends. Also became good friends with the GM there and they don’t have our group pay any longer. It’s just friends playing for fun now.
Not to say that will surely happen, but it’s a great way to at least expand the social circle if you want to work your way toward free games some day ahha
