It started as spinning with a hand spindle using prepared (combed/carded) wool, and has evolved into looking for interesting fleeces directly from the shepherds (plenty given away or sold cheaply around here), figuring out how best to wash and process (hand comb? drum carder? spin directly from the slightly-opened locks?), working on which settings on my spinnng wheel will produce the twist I'm looking for, and most recently, dyeing using Easter egg dye and vinegar, which is surprisingly effective.

Oh, and of course, knitting and crocheting with the results.

I still use hand spindles to spin while walking, watching my kid on the playground, or on transit.

I got myself involved with a nonprofit local group preserving local pioneer era apple trees. They've been DNA testing and cataloging the trees, and had all the info stashed away in google drive and onedrive folders. The founder was looking to step back so they asked me if I wanted to step up as project lead, which I did.

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.

https://heritageapplecorps.org/index.php/Main_Page

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.

Thats awesome! I'm doing apple stuff on the other side of the Cascades (Eugene), starting a cidery and trying to find rare varieties to graft. And doing little software projects like https://pomological.art/. Would love to get in touch if you want people to propagate these varieties you're finding and would potentially be interested in sharing some scion wood!

by andrewhaupt

4/8/2026 at 8:22:23 PM

Oh cool! I've used pomological.art! Great site!

I'm in the middle of building out a similar big project that takes a different tack: looking through every period pomological text (e.g. Apple of New York, Fruits and Fruit Trees of America) and pulling the images, descriptions, etc for every heritage apple variety. Includes the watercolors too. I also pull in every scanned catalog from nurseries selling fruit trees in the PNW from the late 1800s.

The goal is a tool we can use to identify apples, and also have comprehensive info on every variety, using public domain period content.

It's not fully done yet, there are bugs/issues right now but you can take a look here: https://heritageapplecorps.org/varieties/

I think we grafted ~90 scions this year. A lot of them we haven't actually DNA tested yet so no idea what they are. So many of these trees are on their last legs, so our priority is cloning them first, and then once the clones grow, DNA test those as funds are available.

I make my own cider too (though as a hobby). If we ever find ourselves in the same city I'd love to meet up and we can swap scions/cider/etc.

We work with Dr Cameron Peace's lab at WSU. They send us test tubes, we send the tubes back with leaves in them, they run the DNA tests and compare against an apple ID database they've built. We pay ~$50 per test, which is what most of the groups budget goes towards.

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.

by functional_dev

4/8/2026 at 8:05:52 PM

Yeah there's quite a bit of opportunity to reduce processing time along the way.

Couple cool things I've learned about bats.

- They are *extremely* loud in the ultrasound range, 130db echolocation calls from something the size of a mouse.

- On an average recording, the ultrasonic range is almost exclusively filled with sound from wildlife (bugs, birds, etc). I'd expected to see lots of harmonics and whatnot from human-generated sounds but there just aren't that many. It's quiet up there.

- You can leverage these two in combination for sampling by just strapping the recording device to the roof of your car and driving around. The wind and road noise is basically absent and the echolocation calls come through loud and clear. The AudioMoth can be fitted with a GPS receiver to correlate the calls to location (and time ofc)

- There are three primary types of echolocation calls: Search - Semiregular calls just to see what's out there. Approach - Faster rate of calls once prey has been identified. Terminal - Aka feeding buzz, very high rate (200hz) of echolocation calls in the last meter or so of approach. Most of the recordings of bat calls you see on YouTube are slowed down 10x to bring the audio into listening range, but this also slows the call tempo by just as much. They make lots of calls.

- Most bat calls use frequency sweeps rather than continuous tones to pick up both distance and relative velocity of the target (akin to FMCW radar).

- There are more bats around than I realized. I started off by looking for 'good spots', but now I just set the device out on a porch. Many times you'll hear me walking up to the recording device at the end of a recording and there will be 2-3 bats overhead that I was perfectly unaware of.

- Some moths have developed jamming calls that confuse the standard echolocation calls of most bats - https://www.illinoisbats.org/echolocation-jamming-moths/ Some species of bats have developed countermeasures to that.

If you like to work with your hands and have space, build something physical: big and complex, and actually finish it. I built a single engine two seat kit airplane in my garage, did all the flight testing, and now have an interesting way to travel/commute as a result. The "finish it" part is the most important bit. Computer people spend too much time working on projects that don't have a "done" state. Change that up.

by ryandrake

4/8/2026 at 7:11:56 PM

I would start smaller though. There are a lot of half finished airplanes (where the last 20% takes 80% of the time...) and the maker is dead.

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?).

I was as confident as I could be. Had multiple tech counselors and A&Ps give it a good look over beforehand. Also had an emergency plan for every 100 feet of altitude post-takeoff. Did the first couple of flight tests in the vicinity of a minor (class D) Bay Area airport and then did the rest of them (including the riskier ones) over the central valley.

My hobby is organizing in-person meetups for random people to get together, chat and make friends. Barely structured, if at all. I've found this rewarding and ended up making friends this way.

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.

by unsupp0rted

4/6/2026 at 2:23:43 PM

I'm on the other side of this, in that I attend a lot of these.

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.

Between the genuine weirdos, the autistic and/or the neuro-divergent, is there anyone left, really? Do the "normies" genuinely exist? Happy-go-lucky, knows a bit about everything but doesn't nerd out on anything, picks up every conversation subject and listens and holds their own in a manner that is just right? I am genuinely curious about the existence of these "superhumans".

by hackrmn

4/8/2026 at 5:34:19 PM

There are many many of these socially-skilled normies. But, by virtue of being socially skilled, most have already pretty much filled up their social capacity and don't tend to show up at the kind of venues dedicated to helping under-socialized people meet up.

While there is often a "normal" (bell-curve fitting) distribution for individual factors, putting them together can be counter-intuitive.

> 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.

Sounds like a really cool idea. How do you organize the meetup and promote it to people if it ends up being random people? Do you set it up on meetup.com and have a theme at the minimum?

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.

How have you handled this in past meetups?

by gaws

4/8/2026 at 5:13:14 PM

Be courteous, kind, don't accept invites, tell them you're not interested if they're making unwanted advances, and treat them as humans. If they seem receptive and able to handle constructive feedback, tell them what sticks out to you, otherwise just ignore it and move on.

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.

This reminds me of [0], basically just inviting the most interesting people I know (also transitively the most interesting people they know), and just getting to meet people. I would really like to do this, but half the most interesting people I know are PhD professors I rant with because I'm next to them in a lab. Maybe once my network gets bigger. But I would still like to know more about how you do this, as other people doing this accidentally made me some good friendships, and I'd like to repay this favor to others

How I do it is context-specific. I used to live in a place where it's undoable and I was very lonely there. I moved to a place where people are much more open to it culturally and there's enough population to +/- bring in a constant flow of 4:1 regulars to newbies.

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.

by unsupp0rted

4/8/2026 at 5:15:53 PM

Easy two-part process: First part is putting our "feelers", ask/tell a bunch of people "You know, I'm thinking of maybe hosting a dinner party/barbecue/beach day" and see what reaction you get from people. If sufficient people (sometimes just 2) give somewhat interested vibes, ask again what dates people could do it at, then you send out an 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.

by Triphibian

4/8/2026 at 6:25:58 PM

I think a lot of people need prompting for something to talk about. They have no confidence that topics they bring up will be interesting to anyone else. So any kind of gathering that takes that pressure off will be attractive.

I organise events as well and I'm wondering if you ever charged for them. I used to do them for free but so many people signed up and didn't attend later that it was hard to put numbers to book a venue to meet. How did you solve this?

by Gooblebrai

4/8/2026 at 5:56:06 PM

i would do free venues only. usually restaurants are free because you consume food. if that is not an option, it depends on the cost. i have seen events where people were asked to contribute something when they arrive. you can usually announce the cost of the venue and ask everyone to contribute appropriately. if you fall short then next time ask people to contribute more. or keep a running tally during the event until the venue cost is met. from my personal feeling, if it costs more than $1-2 per person the venue is too expensive. find a cheaper one.

Great idea - a lot of the problems in the world are from social isolation, and people finding silos online

Consider mathematics. If you already know enough math to derive the quadratic equation, you might make a small change, like adding X^3 or X^4. See where your own techniques take you before looking up the answer. With just a few pen strokes, you will be playing with an equation for which there is no general solution, or no known solution. In mathematics it will take you very little time to start playing at the boundaries of human knowledge, and it's relatively easy to memorize a few starting points that many hours of passenger travel fly by.

Almost everything you can do on your own is a "solved problem". Why go into woodworking if you can buy an Ikea stool? The point of hobbies isn't to solve problems - that's called a job - but to learn and have fun.

Find a niche where you can resist the temptation to constantly compare yourself to eight billion other people on the internet. Something where success isn't measured in Github stars, Youtube likes, or Reddit upvotes. Once you get in that mindset, almost anything goes. I know people who collect RPN calculators and are having a blast. All kinds of hands-on crafts are great too. I like making electronic music and I'm pretty bad at it.

Not everything. Take cooking, one of the most basic hobbies. It's easy to come up with recipes that you enjoy that you cannot order anywhere.

Or the comment here about designing your own clothes, same idea.

by bananaflag

4/8/2026 at 2:24:54 PM

I started designing my own clothes. The insight was that I spend 80% money on suits that I wear 2 times a year, and the rest was low quality clothing I actually wore.

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.

by shivekkhurana

4/8/2026 at 5:11:42 PM

That's pretty neat, and we should talk. In my household we are currently producing about 75% of our clothing, mostly out of a desire to avoid using fabrics that generate a lot of microplastic waste + observing that newer clothes/fabrics wear out quickly.

Fast fashion forces you to dress for the masses. Loose shirts, baggy pants and shallow pockets is not fashion, its cost optimisation for brands.

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.

amateur liquid bi-prop rocket engines for the High Power Rocketry hobby are gaining momentum. There's lot of opportunity there for performance profiling and even more if you have access to a machine tools like CNC lathes. There's also interest in active stabilization of amateur rockets using engine gimbaling which would put so much more performance in reach.

These guys are legit and actually flying airframes instead of just ignition on a test stand. https://www.halfcatrocketry.com/

The hobby is geography constrained though, you need access to large open spaces. Even small engines are spectacularly loud and igniting one in your garage would scare the crap out of your neighbors.

Edit: if you're in/near LA this club is pretty much ground zero. Tom Mueller of SpaceX's Merlin engine series fame was discovered here iirc. https://rrs.org

I got into HEMA (Historical European Martial Arts) fencing last year through a club in my little town. Olympic/sport fencing is fun, but imagine (safely) swinging a 4lbs. steel longsword with two hands at your opponent instead. It's a ton of fun, a great workout (I burn ~1500 calories per class), and competitive so it keeps my interest.

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.

by jeremymcanally

4/8/2026 at 6:17:37 PM

+1 for martial arts in general. Depending on the art it might not be niche (I'm sure karate and taekwondo are too big for that). But things like HEMA, iaido, eskrima, all kinds of archery, ... are great fun and typically come with smallish & fun communities.

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.

You should try getting _extremely_ good at Trading Card Games. Pokemon, Yu-Gi-Oh, and Magic The Gathering all have extremely active current player bases and loads of places to play across the Americas, Europe, and (mostly east) Asia. Getting deep into card advantage, deck construction, and hypergeometric theory has been an absolute blast. Plus, the online simulators are free for Yu-Gi-Oh and Pokemon are free and pretty current with the paper game. Making new friendships with people not in my usual circles has been so rewarding, I can't recommend it enough. Not to mention the most meaningful contribution of all - winning events moves the needle on the way the rest of the playerbase plays the game. I could go on and on about this.

My wife & I are Scottish Country dancers. It's a social dance form (it's traditional to swap partners for every dance so nobody has to bring a partner, though not required). Pretty good cardio, there are groups all over the world, so it's often not that difficult to find a class.

Other similar social dance forms from the UK are Contra dancing, English Country dancing, and Ceilidh dancing. Square dancing in the US developed out of these forms. Many other cultures have their own social dance forms, with varying levels of formalization.

Meaningful contribution is easy: these groups always benefit from more participants. Scottish Country dance has a formalized teaching certificate program, roughly equivalent to a Master's degree worth of work (and if you're a UK resident it qualifies to teach PE in UK schools).

Using crooked knives [0] for woodcarving.

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)

Traditional archery.

I started a few years back and have been doing it off and on since. It's challenging but a lot of fun.

I shoot a lot of older style "recurve" bows, but the main style I shoot are horsebows, that is, bows that were historically shot from horseback.

They're very lightweight and you can shoot much more rapidly than you can with a more modern/mechanical recurve or compound. Right now I shoot around 20-25 arrows a minute. Not amazing compared to experienced archers, but a lot of fun.

I have a number of bows, but here are my favorites:

Assyrian: https://www.bogararchery.sk/image/cache/catalog/product/boga... Buryat: (No longer available)

I also shoot an English longbow from time to time.

The horsebows use a technique called "thumb draw" which is very different from the way most bows are shot in the west.

Here's a great YouTube channel if you want to explore getting into it: https://www.youtube.com/@ArminHirmer

I got into designing my own knitting patterns. I enjoy that I can customize everything — the yarn material, color (including marling, helix knitting, double knitting), yarn weight, needle size (e.g., resulting in "airy" vs "packed" textures), knit textures (e.g., stockinette, linen, miss, etc.), construction process (e.g., can I figure out a way to knit in the round vs flat?), cables, gradual increases/decreases, selvedge/cord, desired ease, etc..

I wrote software to generate patterns given configurations and keep track of which row I'm on. https://news.ycombinator.com/item?id=40307089

I was into woodworking, then I got into building fly fishing rods from bamboo.

Fly fishing has been around for a long time. They used to build rods by hand out of bamboo - a specific species of bamboo native to southern China - before factories started making them out of graphite, fiberglass, etc. for cheap.

Modern fly rods are a few hundred bucks. If you try to buy a bamboo rod in a store, they run $2K-$5K. They take a lot of time and meticulous work to build, and the result is a functional work of art.

Woodworking is a ton of fun, and challenging. Bamboo rod making is a niche within a niche, and there are not a whole lot of people who still do it ... mostly retired guys with a lot of time. It's a great tradition, and it's about as far away from computers and technology as I can get.

I didn't even know how to fly fish until I built my first bamboo rod.

Here's a great video showing the process: https://www.youtube.com/watch?v=lfTvRxcTuV0

I love how every hobby has its inner nested hobbies and you can seemingly go infinitely deep.

I got back into making electronic music a while ago, and you can dig in deeper by getting into hardware synthesizers. And go deeper by getting into hardware modular synths. And go deeper by building modules from kits. And go deeper by learning electronics and designing your own modules.

It's like a big branching tech tree or tech graph.

With fishing, you can get into fly fishing. And when that's too easy, you start tying flies, or maybe tenkara, or, I guess in your case, making fly rods.

I love it.

Walking and finding history if your location has such history to offer to find.

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!

I highly recommend getting into loudspeakers or audio reproduction in general! Without a doubt the most enjoyable, satisfying, and enriching hobby I've had so far.

A couple years ago I decided to build a pair of synergy horns (look them up!) which included all kinds of interesting stuff! For example, I had to learn CAD, the principles of CNC and how to create toolpaths, what a waveguide is, general woodworking, and lots more. There's also lots of interesting "subhobbies" one may dwelve into such as psychoacoustics, signal processing, LEM/BEM simulations, the optimization of horn geometries (look up AKABAK or Ath4 and their respective DiyAudio threads), analog crossovers, or acoustically treating a room to reduce reverb.

Building speakers and experimenting with bracing and lining/damping have been rewarding for me as determining wether I prefer A or B really requires me to _listen_ in a different way from say, listening to a conversation (or even to music!). It feels very grounding and meditative in a way, and at least in my case, indirectly trains one to notice and appreciate more sounds in everyday life.

A big bonus is that it becomes really easy to throw outdoor parties out in the woods when one doesn't have to rent gear. Loudspeakers and bringing people together is a damn good and rewarding combo.

I've been playing exclusively CRPGs for the last 12 months or so, which was kinda a niche genre before the success of BG3. There are tons of way to beat those games and optimizing how you build your party and characters (what players call "min-maxing") while following a highly narrative story is a lot of fun. Most of them are quite old and often on sales for like 5 bucks on Steam, for which you get hundreds of hours of gameplay. A few recommendations: Obsidian's Pillars of Eternity 1 & 2, Owlcat's Pathfinders & W40K Rogue Trader, Larian's Divinity 1, 2 & BG3, Bioware's BG1 & BG2, etc…

I always meant to go back to Wizardry 7 I think it is. (Or 5, I forget)

I was convinced that a party of all Ninjas and Samurai would be unstoppable, but I never could make it work. I recall leveling up to a point where a high enough character would get 3 attacks per turn, and then when hit counterattack twice. Multiply this by the whole party.

But realistically, at some point this flurry of attacks every round just fell over because you need better magic users for enemies with certain weaknesses. My memory is fuzzy, but it also may have related to the increasingly large hordes of enemies which would dilute the effects of so many attacks.

These are a blast. I went through a phase in highschool where I exclusively played 90's CRPGs. There are some real gems that find a unique playstyle with tons of freedom due to how low fidelity the games are, while still being visually engaging and beautiful. Definitely check out fallout 2 if you haven't tried it yet, it's one of my favorites!

by g00z

4/8/2026 at 6:27:28 PM

Nice to see people discovering these games. I wouldn't really say it was niche until BG3 though, there were plenty of highly acclaimed games long before that.

I’m obsessed with powerlifting. Not only because big numbers get bigger but also the physical changes that occur with a healthy dose of lifting each week. It’s also easy to track lifting stats and there are tons of analysis tools out there if data analysis is something you enjoy.

Also, I’m trying to learn guitar - right now following the Justinguitar.com lessons

by Ancalagon

4/8/2026 at 5:35:11 PM

+1 on this - powerlifting is great due to 1) Rapid, specific initial progress, 2) Highly structured programming (e.g., RPE based), 3) Focus on strength vs. aesthetics is a great way to be more holistic about health & performance, 4) Forcing function on all downstream decisions (diet, sleep, alcohol). Adding +15 lbs on your deadlift can become strong motivation to drive discipline, 5) Drives the importance of recovery/rest on long term progress

by rahulgoel

4/8/2026 at 6:10:09 PM

I do powerlifting 3x a week but I don't otherwise view myself as obsessed with it. I don't have a coach, I don't enter competitions. I know my PRs in my head but I don't keep spreadsheets or stats or have any kind of real programming. I don't video my lifts, I don't post about it on social media. I'm just content with getting stronger.

I really don't get obsessed with anything, which might be a fault as that seems to be a trait of people who are really successful in what they do.

On the other hand, it's the one type of exercise I have actually been able to stick with for any length of time. Started about 5 years ago at age 55. So never too late to try it, even if exercise has never been appealing to you.

by SoftTalker

4/8/2026 at 5:42:50 PM

one of my favorite parts of powerlifting, opposed to hiit or other fitness lifting, is the lack in physical change. i feel like i look the same but can point to numbers that show im much stronger

by boogieknite

4/8/2026 at 5:49:33 PM

True - I guess I am more of a power-builder. Which for those that don't know is powerlifting but also incorporates a lot of bodybuilding-type rep work for aesthetics. You lose some specificity doing this arguably so you're expending energy that would be better spent powerlifting if that was your true goal but this trade off is worth it to me.

by Ancalagon

4/8/2026 at 6:22:50 PM

When I started stronglifts, I didn't tell anyone and people noticed just from my physique after like ~5 weeks of training. Noob gains are insane and definitely cause physical change.

I’m a paraglider pilot and powered paraglider recently. Totally recommended, you get to connect with nature in a meaningful way. Also people who practice this kind of sports are nice. From a tech perspective there are a lot of data generated on each flight you can create your own way to capture that data or use already existing apps.

by dr_robert

4/8/2026 at 6:02:38 PM

I got to do this a couple of years ago. It's super cool! Very much recommend it.

But I'll note that it's super...weird? in the sense that it's like halfway between being both relaxing and excitative, nature and machine. I went in expecting a thrill ride and it wasn't quite that, but it wasn't quite relaxing either (though I'd imagine the more you do it the more it feels like the letter!).

i've always been interested in para-motoring. how safe or unsafe is paragliding? do you think about that aspect before going out for a flight?

by Deanallen

4/8/2026 at 6:06:41 PM

I’ve been flying since 2012 and I always think about safety. Safety is relative but if you do the things the right way you will be ok. A good common sense is super important, and then keep on your progression, there’s no need to skip steps. Knowing the air is a lifetime journey so there is no rush. Also I feel paramotor is kind of safer because you get to fly with light wind or not wind at all, mostly early in the morning or near sunset. In my personal experience this sport change my life.

by dr_robert

4/8/2026 at 7:40:23 PM

I've known 3 people that were into paragliding. 2 of them had near misses from chute collapses and the other flew into a stationery car (he was saved from more serious injury by wearing a full face helmet). So definitely not risk free, based on that sample.

I would recommend finding a local non-profit you're interested in helping, and start volunteering. Don't go in guns blazing "I'm here from Hackernews to save you" but get to know the people and what they do, and then how to help will become apparent.

By local I would recommend truly local and not a "division" of a national non-profit; those are an entirely different beast.

How niche is retrocomputing?

I absolutely love my ancient machines, and I use them to explore period applications, much more than games.

I also love to restore and preserve them. There’s something magical about a Sun workstation Solaris 2 a Frog Design Trinitron monitor. or a Microvax running VMS and DECWindows. Or a multi-user Altair Z80. I think it’s sad a lot of software was lost and some platforms were denied the documentation that’d enable their preservation (looking at you, IBM - document the AS/400 and release old OS to hobbyists).

Railway preservation (full size, not model). It looks crowded when a steam train is running and the moths gather around. The reality, when the trains are not running, is typically quite different, with a small dedicated group. If a place looks too crowded, pick a smaller museum.

Think of all the jobs that have to be done to run a railway and you will be able to find a museum that does it: heavy maintenance, boiler work, fitting and turning, blacksmithing, woodwork, upholstering, painting, catering, engine driving, fireman, signalling, customer service, ...

It's a great way to meet people, learn new skills and work with physical things.

by femto

I don't think chess engines are a solved problem for some use cases. Yes you can make something strong, maybe even the strongest, but can you create a chess engine perfectly tuned to actually teaching a player? Instead of superhuman perfect lines and inscrutable long-horizon strategy, can you teach nearly optimal human play in a way that's actionable, modular and memorable? Can you improve on tournament prep for players against particular opponents or within a particular metagame?

Also, obviously it's your life, and we're here on Earth to fart around, but I have spent a good portion of my life dipping into one hobby after another, as my dad did before me, so I'm half speaking to myself when I ask this: why do you think you can't meaningfully contribute to any of these realms, even now? To me that sounds like some deep seated fear or doubt, some aversion to competition, some overriding bitterness. I'm slightly worried you'll just be back here in another couple of years trying to find another new hobby, unsullied by the efforts and achievements of others. You won't find that! I would actually suggest a particularly expensive hobby: going to therapy. Try that, and learn that you're already enough, and if your contributions are meaningful to you, that's all that matters. Happy to be way off the mark here though.

by thom

4/8/2026 at 5:18:57 PM

This. For those more into reading instead of straight to therapy, Barbara Sher's "Refuse to Choose!" book about living with a multitude of interests can be a good starting point.

Also, making (or maybe tuning) a chess engine to teaching sounds like an interesting challenge, actually.

I've been doing photography for a long time but over the last few years had phases where I got bored of it and tried something new.

I had a long time when I was bored and carried the camera in my pack but never took any pictures, then one day I looked out at the sports center out my window and decided to start shooting sports.

Posting photos to socials I found flower photographs were popular so I take a lot of them and find ways to not get bored. (Maybe I will start focus stacking one of these days)

Since the beginning of the year I have been "going out" as a character who is a bit like a Disney cast member who gets photos like

https://mastodon.social/@UP8/116326541009492328

from people who recognize my character. Like the Disney cast member it works better when people have seen the movie so i hand out these tokens

https://mastodon.social/@UP8/116086491667959840

which spread virally around a university campus, particularly among Chinese students who recognize the huli jing and all the time I have experiences "that could only happen in a manga" when, for instance, somebody who's heard the rumors is waiting at the bus stop for me. Laugh but all my marketing KPIs have an extra zero on the right!

Insect macro photography is an interesting and challenging niche within photography. Trying to find insects and then get a sharp photo, when you have less than 1mm depth of field, is quite a challenge! It also opens up a whole world that you wouldn't normally see.

by hermitcrab

4/8/2026 at 6:00:00 PM

Same, but not the same. I've also been doing photography for a long time and when I had kids I added some gear & skills to shoot them playing sports. After a few years of this I realized since I was already there I might as well shoot the whole team, or both/all teams, since everyone's families would value the photos.

When I was laid off at the end of last year I decided to formalize this and now have a side gig (real, insured business) where I shoot local youth & high school sports for free, but make a few bucks (to cover my equipment costs plus spending money) doing portraits, headshots and team media days. It's proven fulfilling, mostly because since I do the events for free I tend to receive a lot of goodwill and word-of-mouth referrals. Far more than I can handle given my day job.

by eitally

4/8/2026 at 7:30:45 PM

That gig is something I tried to do w/ my daughter's sports for the past 5-ish years. I loved shooting her games and distributing the photos both teams. It was so much fun.

I had a nasty altercation with a parent last fall and now I can't pick up the camera w/o getting PTSD-like symptoms. I'd love to know how "pros" handle dealing with that kind of thing. I had a similar situation years ago w/ a guy who got in my face for shooting on the street at a festival. My solution there was to just stop doing it.

Recreational mapmaking.

Every couple of months the family and I will book out some long weekend to just go to an Airbnb in some random town with some copy paper and just go around trying to draw what we think is around us. Inevitably the lines collide and we have to ask some local passerby for help, and if they know any interesting places nearby, and before you know it they're following along with a colored pencil and some copy paper against a hardcover book too.

My strange hobby was going on what I called "leak walks".

I lived in a town where on any sunny day I could go for a walk and be almost guaranteed to spot a water mains leak I hadn't seen before, which I'd then report and see how long it would be before it was fixed.

The record was over a year for one of them.

( Yes, it was a Thames Water area. )

by xnorswap

If it is a Thames Water area, you are lucky if the leak is only water...

by hermitcrab

4/8/2026 at 7:56:41 PM

There was one I thought was maybe a waste-water leak from the smell, but generally wastewater leaks are much harder to spot, and it's generally CSOs (Combined Sewer Overflows) that are the main problem there, which happen in heavy rainfall and not so much in residential areas.

Mains-water leaks however are easy to spot, because they're damp patches (or flowing/trickling water) in otherwise good weather.

FDM 3d printing is still a wild-west and there are plenty of avenues to explore. Not sure what else to say about that other than as someone with daily and close personal proximity to the 'industry' that cropped up I am well aware that there is plenty of work to be done by enthusiasts and niche-people.

Engineering and machinery is still a place full of exploration if you have the chops. If you don't have them yet then there is plenty of topics within that domain to explore; you'll never run out of things to learn there.

My 0.02c : learn to disregard the crowds and focus on your own work. Just because people are doing something you used to do doesn't mean they have anywhere near the depth of understanding and 'freedom of movement' as you do as a 'resident expert'.

also : the fact that no one is doing something may be a signal; crowds form for a reason. Very few hobbyist bomb-squad folk and rabid-racoon-caregivers, get what I mean?

the GPT3 models didn't keep you from learning about ML. The industry didn't push you from keyboard and printers. You did these things.

If you're trying to lead an entirely one-off human life with total uniqueness from other people then all I could suggest is hallucinogens , but personally I think that the goal of just being unique for the sake of being unique is ludicrous.

Just find enjoyment, that's the goal for me at least.

I knew a guy who found an interesting 3d printing niche: 2 way radios for professionals (mainly SAR crews) are always getting fetched up on clothing, and you're often finding the radio turned off because the knobs got moved. Dumb problem, should have been solved by fundamental engineering years ago - but whatever. He built a 3d printed shroud for a variety of popular radios, and now makes a living selling these.

He's a tech guy, but no engineer. He saw the need (he works on a SAR team), saw the solution and made it happen. Inspiring, really.

I do a bit of 3d printing stuff myself. Personally, I'm attracted that it's getting more professional. I can use it as the impetus to learn real engineering/CAD, etc. Not in an "I'm an engineer" way, but still using real principles to make better things. You don't have to be intimidated if you keep your identity small and let it inspire you instead.

A group of us in our community broadcast many of the local high school sports. Our original setup had a scoreboard that was really clunky to manage and was hard to learn, so I built a web-based version that pretty much any 12 year old with an iPad could use.

I have worked with the logs extensively over time to convert the simple data inputs from the scoreboard controls into charts & graphs that update in real time on the screen to “tell the story” of the game, and generate “talking points” from the data. It allows us to plug in students as commentators and they can talk about the game much more confidently because they can visually see the game's storyline that is based on actual data. “The Trojans are on a 14-4 streak starting late in the 3rd quarter, and that has flipped the lead in their favor” is a lot more fun than “the Trojans are doing well the last little bit”.

It’s been fun (and challenging) to develop the right UI to display the game’s story in a way that is rich yet easy to read at a glance. And it has been cool to see the students increase in how professional they sound on the live broadcast.

by davidgh

4/8/2026 at 7:42:57 PM

I'm very much into niche hobbies: they usually have nice tight & friendly communities.

Below are some of my favorite I'd love to share:

- FPV drone flying: once you've spent 5-10 hours to get initial reflexes for the controls in the simulator, the first flight on a real machine outside feels magical.

- Electric unicycles: the "mind-controlled" PEV, and arguably the best way to get around in San Francisco.

- Foiling: the closest feeling to riding a hoverboard. You can kite-foil, pump-foil, sup-foil etc, but wing foiling is the easiest to get started.

- Knots: tying laces properly just makes life easier, and tying tucker's / voodoo hitches for the first few times feels like a magic trick.

- Cardistry: learning to do a proper riffle shuffle and a few artistic cuts adds some fun to the most boring part of any card game.

I've been using Codex to build a repo that pulls down astronomical datasets and runs simulation to try to find explanation for the hubble tension. Having an agent to do the tedious bits and also having an LLM to bounce ideas has tough me so much about astronomy. I don't have serious hopes of finding anything new and novel but it's still a lot of fun.

Synthesizers! I like it because it's tactile and immediate, and you're not glued to a screen, but can create fun-sounding beats.

Nowadays there are nice, cheapish groove boxes that are perfect for noodling on the couch. I started with the Novation Circuit Tracks, and also really enjoy the Teenage Engineering EP-133. Not to say that I am any good at this, but it's an enjoyable hobby! Bonus if you are friends who are also into it and you can jam together :)

I've also gone down the synthesizer rabbit hole: prophet-6, full modular setup (rip bank account), subsequent 37. It's great fun!

Go to modular meets, music instrument expos like Superbooth, dj sets and live concerts. I met all my best friends this way, everybody is a record collector, beat maker or techno producer. Record conventions are also fun, after couple of occasions you will realize how small the scene is.

Deep in the Eurorack rabbit hole myself. Trying to avoid anything that has a screen and anything that requires a computer to interact with. Patching cables and twiddling knobs is great fun. Sometimes it even sounds good xD

another eurorack rabbit hole is patch.init() - prototyping module. I have 4 and have built:

- an amazing crazy chorus module based on one I built for vcvrack

- a pad synth using the PADSynth algorithm

- a pulsar module

- a fun pitch shifting heavy reverb

endless hours of fun!

I build weird experimental instruments and then play them at the local electronic music open mic nights.

My main instrument is the electroduochord, a stereo two-stringed instrument played with a drone motor rotary magnetic bow. https://youtu.be/G1ftvw-Y6pk

I've also hooked up audio jacks to small solar panels to convert vibrations in light into sound. https://youtu.be/ZF2Rn5YfBC8

Now I'm working on cybernetic drumming and rhythm synthesis. https://youtu.be/oJZeP4Naqxo https://youtu.be/NwNrJLvHuAE

Despite AI starting to crowd this space, I've been spending all of my free time learning music production (doing it the old fashion way without AI). It's a great mix of technical and creative problem solving. Mostly focusing on dark ambient/cinematic composition, playing around hardware synths (Prophet 6, Subsequent 37, modular / eurorack, Digitone II).

If anyone is curious, I put out a single recently (remaster from last year): https://soundcloud.com/vectordust/ion-dunes-1

My main personal goal right now is to release a full length album this year.

by vectordust

4/8/2026 at 6:53:32 PM

you know the OP has "ion" and "dust" in the middle so this was hard to find.

I normally can't stand ambient, but you went a different direction in the middle there. You should put out an album, that probably no one will buy, but maybe eventually you get asked to do soundtracks for things.

anyhow, i used to write music. a lot. sometimes you just have to get it out of your skull... https://soundcloud.com/djoutcold/valley-boulevard-0237

Not sure if you were looking only for indoor hobbies, but I picked up Kiteboarding recently, and it is the most outrageously fun thing I've ever done.

It's like being a kid and jumping off the house with a bedsheet, except it works. Most mistakes are laughed off by splashing in the water. I'm 3 years in and I can jump 7-10m then fly like a bird for 5-10 seconds without consequences.

Even as a beginner, sailing around or just feeling a kite pull you around is such a blast. Keep in mind it's really difficult and pretty much requires 10-20 hours of private lessons.

by embwbam

4/8/2026 at 6:27:20 PM

Really fun! I used to do it too, and I miss it.

How do you combine it with work? Where I live in NL, there are few days where I’m able to go kiteboarding and I probably won’t know until the day off if it’s possible or not.

Very hard to schedule!

by JimBlackwood

4/8/2026 at 7:09:34 PM

I work remotely, and my schedule is flexible. I live in Squamish BC all summer which is great for wind. In the winter we are in UT but my friends take lots of kiting destination vacations.

I’m fairly late in my career though (44yo), so I’ve opted for a lower salary, low stress and flexible job.

I don't know if it's niche, but I like making granola for my friends and family. I give them a big jar and tell them free refills are included ("just bring me the empty jar"). I get pretty good nuts and tend to make largish batches (around 2 kg), and, because of the refills, I get a good sense of who appreciates it — always happy to make more for them. My recipe is here: https://alejo.ch/365

I'm big into anti tech/work related activities. It reminds me that no matter how much I know, or think I know, that I have so much more to learn.

I got into scuba diving while living in NC, and it just happens that there's a lot of it off the coast! The other problem is that it's deep. Diving down to 130 feet sounds cool until you experience hours on a boat only to get a few minutes at the bottom. Eventually I got bothered to learn more about diving.

I headed down to northern Florida to dive with GUE. My instructor was a person who regularly got hit up to dive to exotic places all over the world. Missions like collecting/deploying samples, archaeology, recovery. Here were people meaningfully impacting the environment, science, and keeping technical know-how alive.

I don't know how to convey a the wonder I feel in text. Check it out maybe.

I’ve recently started making bread, at the moment still with fresh or bakers yeast and planning to grow my own sourdough.

It’s not very niche, but as a hobby it’s pretty fulfilling. It allows for a lot of play, and you end with something tasty. Also, makes for a great small gift for friends and family.

by edu

4/8/2026 at 7:22:57 PM

I make most of my bread with sourdough. It is really easy, it takes a bit longer, but there are less steps - just mix some more flour/water (sometimes salt, but I've not had a problem when I forget though others say it helps the taste to add salt - YMMV) into your starter and wait. Yeast is faster by a lot, but it is a lot more complex and so I don't find it worth it.

Animal tracking. I picked it up in college and it has been a real source of joy and a true challenge. It's also something you can do almost anywhere: urban, suburban, rural, out in "the wild."

A lot of people think of it as looking for paw/hoof marks in the mud, but tracking can actually be quite involved, requiring you to understand the environment and ecology as a whole.

For example, tracking birds is outrageously difficult and when I first started out I didn't think it was possible. But the more I learned about birds, their habits (per species), their environment, I started to see signs everywhere. It really got my eyes open and I started seeing the same old places in completely new ways!

And in terms of contributing something, there are all sorts of apps/organization that can help you identify different species and in turn you give them data in the form of pictures, location, etc. I use iNaturalist myself, but there are others.

by davenporten

4/8/2026 at 6:29:53 PM

Sounds fun! Do you have resources to get started?

I do gundog work, it would be fun to do the tracking together with the dog. (I don’t hunt, it would just be to make some walks more interesting)

by JimBlackwood

4/8/2026 at 5:42:54 PM

Not sure if this is an established hobby or something I've just come up with myself, but I've been "dashboarding." Essentially I have a Blazor webapp that integrates lots of data sources (some manual, some automatic) from areas of my life and I use that to visualize and analyze goals and habits. The main page consists of rolling-weekly stats that deliver "integration scores." Each score contributes to an overall score that gives me a general idea of how I'm doing on all my habits and goals.

So for instance, I use YNAB for our family budgeting, and I have it setup so that if I go a whole week without performing reconciliations, I get dinged -1. Otherwise this sits at 1.0. Then I have a score for journaling - my goal is to journal 4-5 times per week, so each time I journal it resets the score to 1, and then slowly ticks down to 0 over time. Then I have a number of Apple health scores that get imported automatically via REST API. This part compiles all the data on calories, relevant macronutrients (I mostly track protein and fiber currently), steps, workouts, etc. and builds a nice visualization. I consider a total integration score of 0.8 to be pretty good - keeping at that level is actually better than seeking for a perfect 1.0 all the time as my theory is that it will prevent burnout and allow for some forgiveness, because I can't be perfect.

It's been a fun project, and one that I generally try to avoid any AI use. Fun to just build and because the stakes are so low I just chip away at one feature at a time, carving out 15 minutes here or there.

by evklein

4/8/2026 at 5:48:38 PM

Do you have more details on this project anywhere? I've been working on habit-building and tracking in my journal for the past year and a half or so, but I'm looking to amp it up a bit more. Your project appeals to my software developer and hobby collector mindset and would love to learn more about it.

by THansenite

4/8/2026 at 6:03:12 PM

Not really, but I'm happy to share more here :)

In all honesty, under the hood it's a bit of a mess. I may have eschewed some of the software engineering best practices in lieu of building something quickly that I wanted. I'll get around to going back through and retrofitting the app with some cleaner code, but for now I couldn't even open-source it without a self-perceived hit to my portfolio.

The project largely started out as something else. I initially wanted a combined TO-DO list and journal. Rather than checking things off I would run the journal content through a local LLM and have it check things off for me based on what I wrote each day. That's yet to be implemented. Then I moved on to an "ordering" system - I was inspired by the way that medical practitioners put in orders once they determined a course of treatment, and thought that might be a useful model to help motivate me to get things on my list done more effectively. I built this, but have utilized it less than I thought. Since then it's mostly been focus on the integrations and scoring system. The whole thing is highly modular, so for each integration I grab a template for the visualization I want to build and then need to reason out how to get the data into the system, which usually involves an API integration, scraping from some online data source, and/or data engineering. It's very fun, because each integration module has its own challenges.

I built the app using a standard stack of .NET core, Blazor server, and the data is stored in SQL server and data operations are handled with EF core. I use the Radzen component library, which I like a lot from a developer perspective but it's challenging to retheme and I'm largely unhappy with the look/feel of the app. This is something I plan on getting to eventually.

Happy to answer any/all questions. It's such a personal, homebrewed app that I can't imagine anyone else would get as much use out of, but it's very powerful and I think the hobby aspect of it could translate to pretty much any other developer.

Fishing. But not just regular fishing, life listing. I catalogue and detail ever fish I catch; the conditions, the type of lure or bait, the rod etc. From there you can get into microfishing with tanago rods, surf fishing etc. It's can get quite deep and a good additional hobby for people who love to travel.

by ffsoftboiled

4/8/2026 at 5:44:17 PM

I also take notes when I fish. It's less about recording a life list, and more about trying to collate what is otherwise very thing spotty data enough to get better at fishing.

As someone who has learned a lot of skills and hobbies online and likes sharing info, fishing has been a really interesting different world. Because anglers are effectively competing for a scarce resource, specific information about good fishing spots is understandably not shared widely.

So you have to put in the time yourself to try spots and see what produces. But in order to catch fish, you need to be at the right place, at the right time of year, at the right time of day, with the right lure, and the right technique. Get any one of those wrong and the only signal you get is "no bites". That makes it really tough to learn and improve.

I've found that taking detailed notes helps me see patterns in what works that would otherwise be hard to see.

Echoing others, Chess engines certainly aren't a solved problem! In fact there are a lot of niches that are absolutely starving for effort. Ones I'm interested in are related to Chess variants and puzzles.

Fairy-Stockfish is a fork used by LiChess for the variants on the site, but it can now play a multitude of games from Xiangqi (Chinese Chess) to Shogi (Japanese Chess) to a crazy modern variants. There's a variety of tools to train new neural nets for these variants, generate opening books, puzzles, etc. You can play some of them on PyChess (pychess.org). These are projects basically run by a couple people with huge backlogs of bugs and feature requests. An enthusiastic developer can easily get involved! Or just enjoy playing different variants and getting involved with the player community.

by autocorr

Ohh about fairy stockfish, I had actually looked into it for something like spell-chess (which is an completely unsolved problem!)

I was playing chess with one of my friends and we played spell-chess which is an clash royale/clash of clans x chess thing where you get two spells of freeze and jump

Freeze allows you to select a tile and have a 3x3 square radius which freezes those pieces

Jump allows you to select any piece (opponent or yours) and it will effectively allow you to jump over that.

When me and my friends were playing, I kept trying to do something wonky to find the most optimal play. I had thoughts for a day or two to find/make fairy stockfish or atleast had the idea to do so but not the experience to do so but I certainly wished even from the end point perspective as to what/if the game was solved. I don't know but these things make me feel as if perhaps, just maybe, the game can be played a certain way where even in the best game, its not draw but rather a particular side wins (effectively solving it),

I felt like these spells were too overpowered so there was an possibility about it, you just made me remember a lot of things about these things that I had thought. It was these thoughts which randomly led me to discover fairy stockfish which is an really interesting project!

I'd suggest you try out something completely offline. My next candidate is flintknapping, but there are lots of really interesting historical crafts that are in need of preservation and are extremely interesting to learn and gain expertise at.

Woodworking, oil painting, pottery, analog synthesizers, animal husbandry, spinning and yarnmaking, knitting and weaving, sewing, pattern making, metalwork, welding, endurance running, rock climbing, beekeeping, brewing and distilling, the list goes on and on. Contrary to popular opinion they are all extremely technical and demanding fields, and getting to reconnect with the physical world and the people in it, as well as history, is extremely rewarding.

by jaggederest

All primitive skills are great fun to learn. A logical followup to flint knapping is arrow making and bowery. There is something magical in making lethal ranged weapons with sticks, rocks, and string.

There's a lot of legacy / retro coding out there that despite the output being used by anywhere from hundreds, to thousands to even millions of end-users, it still involves small tight night communities per project, sometimes they overlap somewhat. I've mentioned it before, if you follow people reverse engineering Shockwave, you will note that they are all on the same communities to capture as much wisdom from others as possible. In niche reverse engineering communities, the smallest thing can be a life changer.

I have been spending an inordinate amount of time trying to find the owners of the old Digital Research "Concurrent DOS" operating system. There's a lot of interesting turns in the search and it's been fun to document.

I've written a blog post about it [1] though there have been a few updates since I've written that.

I honestly think it might be a fun thing for me to keep doing, whether or not I'm successful with my search. I think there is a lot of old software that is just sitting on old hard drives that is waiting to be preserved.

Hnefatafl, a simple board game that was played by the vikings and others who had frequent contact with them. Or rather, what we play today is an approximation of what they played back then as we don't really know the exact rules they used. It's interesting in that unlike chess and others, it is asymmetrical, and there are a number of different variants each with their own challenges and different balances between attacker and defender.
