Ask HN: Any interesting niche hobbies?
In 2022 I was toying around with OpenAI's RL Gym, right when the first non-instruct GPT3 model came out. I was thinking about getting into ML a lot more, but hesitated. Before that it was 3D printers, mechanical keyboards, drones, etc. All of these have exploded, and while they are still very interesting, I do love my Browns and manage Prusas for my local hackerspace, they have just, for the lack of a better term, industrialized. I'm also now in a position where I have time and money for it, not like when I was 15 and rating Ender motherboard upgrades I knew I'd never buy.
Right now I'm making a chess engine, but that's already a solved problem. There's also biohacking, and while designing chips to go into my body is really interesting, I only have one, and don't want to push it too far. One promising idea is a kind of 'Personal Computer 2', where people try to innovate HCI, and while I really like that and do have some research ideas, I'd like to explore a bit more before delving deep into it.
I took the info and organized it into a nice wiki-style site with maps and descriptions so everyone in the community can learn about the old orchards.

I've also learned how to prune and graft hundred year old apple trees and now have a couple dozen young grafted trees growing in my garage, all clones of local hundred year old trees, some of which genetically tested unique and are of currently unknown varieties.

I've been working on a ukulele for over a year now and it isn't close to done yet, and this is a much smaller project. (Or maybe I should say I've been working on raising kids for a decade and there is another left?).
Bat detection/identification with ultrasonic recordings. It's been fun building the data pipeline to manage the ~30GB+ of WAV files generated every night, run through some identification processes (currently using https://github.com/rdz-oss/BattyBirdNET-Analyzer) and build a UI (mostly vibe coded lol) to help with replay, cataloging, etc.
I'm using an AudioMoth currently (https://www.openacousticdevices.info/audiomoth), am thinking about extending it to do some of the preprocessing in the field to scale things up a bit.
People pay vast accruing cumulative sums over time to go to the gym and my exercise pays me with every single walk. Some of that modern human history I have found dates back hundreds of years in the form of coins and bottles while some of the native human history I have found dates back 10 thousand years. I cannot neglect the fossils either as the oldest I have found reviewed by an expert is said to be Paleozoic tabulate coral being over 251 million years aged.
Thanks to gravity everything lost in the past is under our feet and as digitalization has taken over our global society, created by some of those reading this here, there are not many folks walking let alone looking. I found my first item over 14 years ago now and while my partner HATES the aggregate volume of the things I have collected she cannot neglect the uniqueness, rarity and value of some of those items. Every single walk inspires real motivation however one needs their health first to take that walk.
Stay Healthy!
You have to accept that 5-15% of the people who would show up to something like this are genuine weirdos you probably don't want to be around. And another 10% at any given meetup are autistic or neuro-divergent but well-meaning, kind and full of interesting insights and hobbies, although perhaps difficult to socialize with, at least until they get to know you're well-meaning too.
These challenges come with the territory. You end up talking to people you'd otherwise never meet in the normal course of your life, and it's neutral at worst and wonderful at best.
I made a big effort about 12 years ago to go to a bunch of these (like three meetups a week and trying out a variety of different meetups), but now I mostly stick to a couple of them as I don't have as much time or energy for it anymore. But I've met most of my current friends through those meetups.
Find one you like and keep showing up until you're a regular, and get to know people slowly, and if they like you they start inviting you to things outside of the meetup, and then eventually you end up being friends.
I've done this with three different groups over the years and despite naturally being shy and an introvert I've ended up making friends at each one.
At the height of me doing this (like ten years ago), it got to the point where I'd go about my daily life and about once every other month I'd run into random people I've met at meetups also out and about. Like go out to dinner and spot someone I knew from a meetup also showing up to the same place, or run into them shopping at a Best Buy or something.
Meetups where you do a shared activity seems to be the best, like hikes or movies (+ dinner afterwards) or board games, since you can always focus on the activity if you don't feel like being social, and you have that activity you can always talk about as a subject.
Heh this has a total “nobody goes there anymore, it’s too crowded” vibe.
> Even when considering just three dimensions, fewer than 5% of pilots were “average” in all. [1]
I would guess many/most people probably think they fall into either (1) the normal bucket or (変) the weird/fringe bucket. Either "I am pretty normal" or "I am an outsider". How many think "We're all fairly different once you cluster in any 3 interesting dimensions!"?
But people feel that dichotomy, which makes me think it is largely about perception relative to a dominant culture: the in-group versus out-group feeling. For example, atheists might feel like outsiders in many parts of the U.S., but less so in big cities and in other countries. In dense urban walkable cities (like NYC), people see diversity more directly and more often. Seeing a bunch of people is different than seeing a bunch of cars.

I've been to a lot of meetups and it's definitely hit or miss and obviously depends on the sociability of the people that show up. The better ones I've attended are generally ones where people aren't trying to network for work purposes and are there literally to just socialize. The networking ones I find very dull as it's people just talking shop and career and if you've nothing to offer them on the career front, they move on quickly.
I have literally never been to any kind of organized gathering where this wasn't the objective of most of the people there. Family and children's events excluded (sometimes).
How have you handled this in past meetups?
Basically the same way you handle the exact same situation outside of organizing meetups, but maybe a bit extra on the friendly-and-try-to-not-traumatize-people-who-might-be-trying side of things.

I advertise on local meetup platforms and in local social media. And I go to so many meetups myself that when people ask me what my hobbies are and I tell them, they get curious and self-invite.
You'd get a bunch of people who say yes but then don't show, this is normal and don't take it personally. Secondly, maybe the first 2-3 times it'd be hard to get people to commit, but once you do it more regularly, people will find it easier to commit to something they know you're already committed to.
I think the 10% neuro-divergent is a positive as it being ND can be very isolating for people
Makes me think a focus around ND alone would be a great idea
Yep, thats me.
It will save both sides a lot of time.
They're essentially a combination of a plane, spoke-shave, draw-knife and gouge but all in a one handed tool. They were primarily used by Native Americans to build things like canoes, snowshoes, baskets etc. I first found about them from reading John McPhee's Survival of the Bark Canoe [1] but there are lots of uses of them on video on the website below (which I created).
If you want to get into woodworking but want only a few tools and/or a very portable tool, highly recommend.
e.g. in theory you could build an entire canoe with an axe, crooked knife and 3 or 4 sided awl (and a lot of time, patience and materials)

I flipped it, and made suits and pants that I could wear everyday.
The fast fashion stores were crap quality, my body is not a template size and I care about fabric and comfort.
The process was to learn how to sketch, to determine fabrics, colors and fit. I made pants that stay comfortable even after I eat food, I made suits that I can wear casually.
I don’t stitch myself, for that I worked with multiple workshops, until I found one that works for me.
Took me about 3 years to reach a point where all my wardrobe is designed by and for me.
There were multiple side effects on my confidence, my life, and the opportunities coming my way.
I didn't want to dress up like a boy. Me and my friend were in Paris when we got inspired by the floor(fashion_sense). I was already working on my clothing, but that day we promised each other that we will not be underdressed anymore.
He opted for off-the-shelf formal clothing: high quality shirts, and pants. I went all in.
First I found markets that sell cheap fabrics, so I can experiment. I travel a lot, so my clothing had to be designed for all weathers. I'm Indian (Bharat), but look racially ambiguous, so I also wanted my clothing to reflect my roots and culture, yet be modern enough for any room in the world.
I run a company, and write code, so comfort was paramount. But I also had meetings or presentations so I wanted to be presentable.
Started with pants, because I thought pants are easy to optimise, and I just need a black, gray and dark blue one. Over 5 iterations, I reached a design with elastic straps on the side (because when I eat food, my tummy bloats a little and its uncomfortable to sit down), and loose on the thighs. Imagine pyjamas, that look like pants.
Then next step was to experiment with jackets and shirts. I played with fabric, patterns, and finish (zippers, titch buttons, different cuff lengths and styles, different collars).
My friends started noticing, and I also consulted some clients. Then I gave a talk about it. This is one of my skills that I discovered by first principles. The best part is that I met my girlfriend because she noticed my aesthetics, and she told me that she makes her own clothes too.
Then there's the whole nerd layer of reading all the original sources from the 15th century, attempting to retain the historical character of the techniques while engaging in real combat, etc. It's both intellectually and physically stimulating.
Edit: before you think these arts are immune to tech, I once had a student who built a (truly awful) sword fighting "robot" to help train deflecting strikes. Not quite up to par with Dune's robot swordmasters.
