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.

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?

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…

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".

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.

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?

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.

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…

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!

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)

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 a…

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.

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 fi…

How did you start out? Was it through local classes?

I’ve been learning Gregg Shorthand (Anniversary) since the start of the year. It’s a fun challenge even if it feels fantastically obsolete at this point with transcription models getting better and better every day. I’ve always liked paper-and-pen notes, so the idea of basically learning analog Vim was appealing :)

I've been making a seabed simulation of the seabed for interacting with polymetallic nodules. The idea is these nodules contain a lot of cobalt, but due to their location on the seafloor they're had to access, making mining difficult.

It took me a while but I finally got my hands on some polymetallic nodules (basically the rocks you find on the seabed that contain cobalt) which I'm scanning and will hopefully have uploaded soon. Tragically the nodules were damaged through shipping but it's all I have, especially since the first shipment was stolen off my porch lol. It's build with Project Chrono using C++ https://github.com/thansen0/seabed-sim-chrono
