Mine is mapping. I am a big OpenStreetMap contributor and I have mapped many towns near me that were previously completely unmapped.

    What is involved with town mapping - do you have some kind of Google type camera rig on your car or a GPS device that automates the process and just drive through street, or what?

      You use aerial imagery and trace the buildings, roads, and other features using points on a grid.

        Is that your own imagery, from drone footage for example, or are you basically copying Google Earth?

          It’s from Bing and Esri. It’s not copying anything, as aerial imagery is a different thing than a map. Also Bing and Esri imagery is specifically allowed to be used for OpenStreetMap purposes, likely because companies benefit from OSM data.

        I watched the video you linked. So it’s enhancing existing maps - I was thinking it was building the maps themselves from scratch. A long time ago I worked with a small company that created digital street maps for cities to use for utility work etc.

          It can be making maps from scratch. There are a lot of places where the map has no features, mostly rural areas.

    Philosophy and some sciences, but I’m not very knowledgeable. I know people say you don’t need to be an expert in order to enjoy things, and I agree, but then those aren’t special interests either, right? I love my music, but I know few bands. I love singing, but I lack technique. I like horror stuff, but I’m pretty picky. I’d like to be fit and practice sports, but my health is an issue. I like some beauty topics, but I’m not interested in applying them. I enjoy eating, simple food though. Some games are fun, but I mostly repeat the same ones. I like mountains and forests, but just for a day or two. I’d like to read more…

    I’m really a master of none.

      Yeah, I truly cannot understand how people really get into things. I don’t play poker with my friends because after an hour I’d rather do something else. I have never finished a video game. My interest in things always just seems to fizzle out. I do a bunch of stuff well enough, but I’m not even sure I want to do them.

    Does raising and training ducks count? I’m really good at it. I have care down to a science and I’ve done quite a bit medically because there aren’t any vets that treat ducks around me. I’ve rehabilitated crazy injuries, performed minor surgery, treated severe malnutrition and vitamin deficiencies.

    I have trained all of my birds to listen to basic commands and they know their names and respond to them.

        I got into chickens when my sister started 4H, and when our chickens died suddenly, my grandma got us 3 ducklings as a gift without consulting anyone. They imprinted on me immediately and I was like, “I guess this is my new obsession because I’m a mother now.”

        That was 8 years ago. I started off with a Muscovy male, a muscovy female, and a mallard female. We rescued a second Muscovy female a couple years in. I moved to my own place in 2022 and brought the remaining birds with me, which were the Muscovy male and mallard female.

        I ordered some more ducklings and rescued a couple birds over the course of 2022 and 2023. Right now I have:

        2 female muscovies: Mama Duck and Lady. Mama Duck fights me over eggs, so I have to pull a Skyrim move and put a bucket on her head so I can take her eggs without her attacking me. Lady is very sweet and shows me her eggs and acts all happy when I compliment her best and thank her for the eggs.

        A tiny male mallard and his mate who is a female mallard that looks like a male but has laid eggs. Little guy is Sonic (because he runs SO FAST) and his mate is Amy. Amy went through duck menopause about 6 months after I got her, so that’s why she looks like a male in terms of feathers. Without her ovaries producing female hormones, her feathers defaulted back to mostly male. She and Sonic were rescued from a local family who couldn’t care for them anymore.

        A male Pekin that doesn’t have male traits but I’ve seen his dick a few times. His name is Salt. He is a lil chonky.

        A male khaki Campbell named Pepper. He was purchased with Salt as a baby. They were on sale for 25% off and were 100000% an impulse buy. They’re besties and don’t leave each other’s sides.

        A female khaki Campbell named Capri-Sun who yells a lot

        A female Pekin named Judy. She’s named after judge Judy because she’s always squinting at me in a judgmental way and interrupts me with sassy quacks any time I talk to her. She’s done this since she was literally only a day old. She has a distinct quack that has a squeak to it.

        A female golden layer named Cayenne who is hella chill.

        A female Cayuga named Fashionista who is slowly turning from black to white with each molt of her feathers (that’s normal)

          Wow! That is so awesome and I’m super jealous! I discovered a park semi-close to me last spring that has a bit of a Mallard population, and apparently seasonal Gadwalls. As you might imagine, they’re not super interested in most humans, but still super fun to watch.

    Hedge laying. It’s a technique where you almost cut through the stems of the plants in a hedgerow in order to bend them down. This promotes the growth of new shoots and results in a very dense hedge, which historically was done to make sure animals didn’t escape or enter pastures and fields.

      Is a hedgerow more economically feasible than, say, a chain-link fence or any other kind of fence, really (fences are expensive)? About the same? More expensive? What about comparative difficulty? Is it the kind of thing that takes years to grow out?

        I’m not exactly sure. A chain link fence is a one time expense as opposed to a hedge which is a living, growing thing and so needs continuing upkeep. And yes, it can take a couple of years before the hedge is ready to be laid… There’s also the used space to consider, as a hedge is a lot wider than a fence.

        I guess it really depends on your specific situation.

          My dad built a house out in the sticks. He initially built a fence out of pallets, but it didn’t stand the test of time. Upon looking into various fence options, he realized that even the cheap ones aren’t cheap. I don’t think he’s ever considered a hedgerow, so I wondered if it might be an option. Aside from the cost, I doubt he’d have the patience for it, from the sound of it.

    iNaturalist

    i upload photos i take of plants, birds, mammals, reptiles, fungi, and bugs. The observations (photos + location + annotation) are uploaded to a public database accessible to researchers and universities.

    I’ve been involved in multiple species range expansions, and i’ve documented both endangered and invasive species. Pretty fun!

    The Android app is very good. The iOS app is good for uploads, but lacks a lot of browsing features like search filters and phylogenetic trees. If you are on iOS i suggest using it in a browser except for observation uploads

    You can also upload audio recordings for bird and bug sounds. It’s amazing what you can learn about your local ecosystem!

      I love iNaturalist. I lived out in the woods for several years and would see so many different bugs that I didn’t recognize. So when I discovered it about 2 years ago, I started taking pictures of every bug I saw and uploading them to the app to learn what they were. And then in August last year there was an unusual explosion of mushroom varieties in our yard. That’s the one area where iNaturalist is a little weak as it really struggled to give me good ID’s for a lot of them. But it should only get better with time.
      I’ll see if I can find some mushroom photos to share here.

      Edit: one of my favorite mushroom pics I got during the mycological explosion:

        With mushrooms i often rely on other citizen scientists rather than the ID robot. There are some very friendly and active mycologists who can be a big help figuring out an ID or telling you what to photograph next time to get better data

    I know more about the Doom engine than I do interpersonal relations. Did you know you can completely destroy collision physics via writing over memory addresses if you shoot a bullet weapon at a stack of corpses?

    Edit to explain: Decino has a great video explaining it in detail. Link is above, tho I’m at work and can’t watch it to double check. Poorly explained from my memory:

    When you fire a hitscan attack (press button, gun shoots a bullet that instantly hits with no travel time), the engine does a number of checks for collision, range, etc. If you have a stack of actors (decorations, monsters, ammo, etc) and you fire a hitscan attack in the direction of the stack, it makes a call to check collision for each individual actor in that stack. The actors don’t have to be all on top of each other, it just matters that the hitscan line crosses over those actors.

    If you have a stack of 129 or more actors and fire a hitscan weapon, the game will essentially overwrite parts of the memory address. I don’t understand a lick of that stuff myself, admittedly, I’m no programmer. If you have something around ~140ish actors in the line of fire of a hitscan attack, the Blockmap system for checking collision effectively gets erased. Projectiles pass through everything, bullets and melee do no damage, players and monsters walk through walls, and you can’t interact with things like switches. You can fix it by saving and loading, though if you’re recording demos you can’t save.

    Game preservation. I got into it last fall when I learned about OpenGOAL for the Jak and Daxter games. I grew up with those games and were some of my favorites from that generation.
    I then learned how easy it was to rip PS1 through 3 games and how simple it is to set up the emulators for each console. I have a sizable collection of games for those generations, so I started ripping.

    I then remembered watching LTT’s video about how to jailbreak the Switch. I bought a used Switch from a friend pre-pandemic, but never played the games because I never cared for playing on the Switch itself. So I checked if mine was old enough to jailbreak (Nintendo patched the exploit out of the Switch about a year after it released) and, lo and behold, it was.
    It wasn’t easy jailbreaking it. It took several hours over 3 days to do it; I would make some progress, then hit a roadblock I couldn’t figure out, so I’d stop and come back the next day. I’d get a little further, hit another roadblock, and repeat. Once I managed that, I ripped my (small) collection of Switch games and played them on Ryujinx. Now that I could finally play them on my laptop whenever I wanted, I actually had a desire to play them and managed to get through BotW in January.

    Then I figured out how to jailbreak my Wii (which is pretty easy, I recommend everyone do it to theirs), so I could rip those games. It can also rip GC games, so I didn’t need to find and jailbreak one of those to do it.

    When I learned of shadPS4 this summer and the progress it was making toward playing Bloodborne, I spent $400 on ebay to get a gold PS4 with firmware 9.0 so I could jailbreak it and start dumping PS4 games.

    At that point I saw how much space all of the games I ripped took up on my laptop, so I bought a NAS from a friend who was upgrading theirs and set it up with two 8TB hard drives in RAID 1 and stored all my games on there. It’s currently about 60%+ full.

    Over Halloween I went to a used game store and saw they were selling a Wii U for $160. I bought it and jailbroke that as well and started ripping those games.

    I bought an OG Xbox to jailbreak, but I need to open it up to replace the clock capacitor first. Otherwise it could leak and my effort would be for nothing. I just haven’t got around to it yet.

    I realized this was a passion of mine when I accidentally borked my PS4 and it would only boot into safe mode. I was 100% willing to completely wipe it and start the jailbreak from scratch so I could keep doing it.

    All told, I’ve ripped about 400+ nearly 600 games (I finally counted) in the past 15 months, spent dozens of hours ripping them, and have zero intention of stopping. I only think about how I can keep expanding my collection. Right now my next consoles will be the 360, PSP, and Vita.

    Edit: rephrasing and adding a little more info

        I’m sorry :/ There’s gotta be a way to get those screws out. It’s 100% worth jailbreaking your Switch. Being able to play BotW and TotK on your 27" 1440p monitor significantly improves the experience.
