Anyone remember this?

I vaguely remember a video about history of weapons that goes like "rock, fast rock, pointy rock, (...) spicy rock dropped from big metal bird" (nuke) but I can't find it again. Does it ring a bell for anyone here?

Even though they're bigger, Generation 2 Starlinks are fainter than Gen1
  • SpaceX wants new regulations regarding satellite brightness.

    Their own satellites (at least the second generation ones) fulfill the requirements set by the astronomers at the Rubin Observatory, +7 mag (10x darker than the original ones). Meanwhile the satellites of the competitors OneWeb and Amazon can't fulfill them without major design changes, because the altitude the satellites orbit at makes a significant difference.

    If the recommendations of the Rubin Observatory report were turned into regulations now, Starlink would barely be affected (they'd just have to stop the gen1 sat production a little early) while the competition would be set back several years.

    Solving community fragmentation

    One issue with the fediverse right now is that there are many redundant communities. Like !technology@beehaw.org, !technology@lemmy.ml, !technology@lemmy.world, etc all having essentially the same topic.

    I think the easiest solution to this is to take reddit's multireddit feature, allowing users to create their own "technology" multi-community that includes all the popular technology communities from all the instances. Thanks to federation, the user could interact with this multi as if it was one big community. Perhaps a way to share the multi with others so that all the component communities get federate-mirrored to the new user's instance would be needed too.

  • If per-user instance filters are implemented, perhaps instances could have "default blacklists" for new users for stuff like exploding-heads or lemmygrad that most people don't want to see, with the option to manually un-block them if someone does want to see that.

  • Testing if the video player works...
  • Nope, linking the video file directly creates a download link. It doesn't display a video and clicking the link downloads the mp4. Adding onlineplayer.com makes it try (but fails) to display a video inside lemmy, but clicking the link plays it.

    Trans women have no advantage in elite sport, new report finds
  • Emphasis on medically transitioned.

    Some people seem to think that lgbt activists want to make it so that any male athlete could just put on a wig, say "I'm trans now", steal medals from women and then detransition the next day. (As depicted in that Futurama episode.)

    Letting trans people who have medically transitioned for several years compete is a very different beast from letting anyone who claims to be trans compete.

  • Trans women have no advantage in elite sport, new report finds
  • Key detail being "after transitioning".

    Someone who says that they identify as trans but doesn't medically transition at all could still wreck competition. So sports competitions can't just allow all trans people, but only those who have medically transitioned. Then they need to figure out how to draw the line when it comes to different hormone dosages, surgeries, etc...

  • Satellites keep photobombing space images. Astronomers need a fix
  • The bright line is Starlink satellites immediately after deployment.

    Starlink satellites do have stealth features to make them less bright, but those are only active in normal operational mode. Immediately after deployment and while dodging space debris, they are more visible.

  • Satellites Keep Photobombing Space Images. Astronomers Need a Fix
  • Because SpaceX satellites are coated in special reflective materials to reduce brightness. That requires the satellite to be oriented the right way to reflect the light from the sun away from the planet, so it only reduces brightness of the satellites in the operational orbit. Satellites immediately after deployment are far more visible.

    Subscribed communities copyer

    I made a little thing to more easily move to another instance:

    A way to quickly grab a list of your subscribed communities.

    Go to your list of subscribed communities, <yourinstance>/communities/listing_type/Subscribed/page/1 and create a bookmark with the following code as link:

    code

    ``` javascript:(function() { const currentHostname = window.location.hostname; const table = document.getElementById('community_table'); const anchorTags = table.getElementsByTagName('a'); const communityUrls = [];

    for (let i = 0; i < anchorTags.length; i++) { const title = anchorTags[i].title.substring(1); const parts = title.split('@'); const community = parts[0].trim(); const domain = parts[1] ? parts[1].trim() : currentHostname; const communityUrl = https://${domain}/c/${community}; communityUrls.push(communityUrl); }

    const urlsText = communityUrls.join('\n');

    navigator.clipboard.writeText(urlsText) .then(() => { alert('Community URLs copied to clipboard!'); }) .catch((error) => { alert('Failed to copy Community URLs to clipboard:', error); }); })();

    Clicking this bookmark will automatically copy a list of all your subscribed communities and format the links so that you can pop them in the search bar of another instance to subscribe to them from another account.

    It can only scrape what's on screen, so if your subscribed communities list is several pages long just click the bookmark for each page.
