  • No problem! Embed just means the picture lives on a different computer, and you get it from there.

    I haven't used the website much since I came from the Reddit blackout, but that issue sounds like an issue with the website. I think the apps are a better experience than the website. They let you save comment drafts, use volume keys to go up and down in the comments section, and get back to where you were before opening a post rather then back to the top.

  • Lemmy mentioned on /r/europe
  • Welcome! No, communities are our version of r/. Instances are like the server your account or community lives on. Yours is .world, mine is sh.itjust.works. Look after the user name. .world that's a pretty good one.

    The instance admins can ultimately decide what sorts of things they want on their instance. Some will allow uploading large files but others won't because it's storage intensive. But you can embed from other sites too, so it's not a big deal.

    Most all the instances talk with each other, so once your set up, there isn't much of a difference. Just make sure your using the 'all' (all instances) instead of the 'local' (only .world) tab.

    Btw, you on mobile or desktop? Lemmy has a lot of good apps, I'm using boost right now.

  • MIT builds swarms of tiny robotic insect drones that can fly 100 times longer than previous designs
  • Looks like they hovered for 1000 seconds. It was previously stress limited such that the joints would break after just a few seconds. I think they might still be tethered for a power source, I haven't seen any of these micro flapping bots include a battery yet, and they didn't mention that they did.

  • TIL about this picture of horseshoe curve taken at midnight with 6500 flashbulbs

    For the 100th anniversary in 1954, Sylvania set this picture up with thousands of flash bulbs.

    Apparently the fireworks were added in post.

    Is green hydrogen a bubble?

    What do you think? Can the low efficiency be overcome cost effectively?

    Triangles are all the rage!

    So many Doritos to choose from.

    Interesting plane spotted over Chengdu, looks like a side by side seated trijet.

    Mechanical Hand Testing

    Ian Davis has been working since he lost his fingers to design and build a mechanical hand. He's now looking for other amputees to help him test the design. It's a really cool project, I love following his progress!

    Changing Models of Villagers on Bedrock

    Is there a way to get villagers with separated arms on bedrock? Would I need to write my own addon? I don't see anything built for that currently.

    My end goal would be to get villagers to look like dwarfs, like this resource pack.

    TIL computers can sometimes grow crystals

    Tin in solder or some other meals can form spiky crystals when under stress. These whiskers can form short circuits if not properly insulated or not alloyed with other metals.

    Training reactor that you can see though is pretty neat!

    Apparently reddits nuclear subs are anti nuclear now, as they won't let this video be posted.

    Livestream with more info about Kyle Hill videos beginning banned from nuclear subreddits. Discussion starts at about 17min in. https://www.youtube.com/live/LF-AMZYrLYs

    Tianlong 3 booster static fire test lifts off instead

    Scott Manley video, looks like the hold down claps may have ripped the bottom off the booster, allowing it to take off.

    Solstice - 5

    Stunning short film. Seems scarily plausible, we won't lose control of AI, the people in change just won't care enough to control it.

    [Question] Digital additive sine wave synthesis from equations

    Anyone have tips on digital additive synthesis? I'm looking to define a curve for the overtone series to follow and generate and combine sign waves from that. Looks like there is a way in Python?

    https://medium.com/@noahhradek/sound-synthesis-in-python-4e60614010da

    Anyone have thoughts or experience with generating sounds in Python? Are there any artifacts I should watch out for? Is there an easier way to generate tones from equations for their overtone series? Thanks!

    We are still flying half a ship!

    Another happy landing. I can't believe starship managed to land gently after burning half the flap off!

    Walking stick for your hike!

    Just make sure to return them when you're done! Maybe even add a new one if you find one.

    The one I used was very nice. Has a nice heft all the way down, and was very straight.

    Disable tracking on Chevy Bolt 2019

    OnStar reports location and speed data to the car manufacturer. Sometimes they will sell this data to insurance companies to raise your premium, as several news stores pointed out a few weeks ago. I couldn't really find an advantage to OnStar, (I have my phone to call emergency services) so I disabled it by pulling it's fuse.

    For my 2019 bolt, it's f31 in the instrument panel fuse box, just down and to the left of the steering wheel. The fuse box cover comes off when you pull it hard from the bottom.

    I was able to find which fuse went to OnStar in the owners manual and labeled on the inside of the fuse box cover. You should be able to find it for your model car there too if it uses OnStar.

    I did have the casualty of my speaker for calls and texts. I'm not able to use it right now. I'll see if I can dig in and reconnect it somehow, but we'll see.

    Who knows that other into they're snitching back to GM, or what they could do in the future, so I recommend disconnecting it. Good luck!

    Reentry looked so cool!

    Amazing views, especially for live! I don't think we've ever seen reentry plasma on a live stream before.

    PS, does anyone know how to get a direct link to a twitter video? I used to be able to through nitter, but that shut down. I can't figure out how to get twitter videos on lemmy directly now.

    POSITRON JourneyMaker, upside Down Portable 3D Printer

    Folds down to fit inside a 1kg filament box. Upsidedown let's the complicated moving bits be in the base where there's less vibration. Krylan3D originally designed this to easily take in a backpack back and forth from college, but is now hired and working on designing other 3d printers. So the community has made improvements and made it easier to make yourself. Parts cost about $550.
