  • Okay, just back of the envelope math. Assuming the car is truly 550nm, so the blue car is 400nm, and the red car is 700nm... How fast is the car going?

    Napkin math says 0.27c.

    Δλ=λ(V/c)

    Now someone else can figure out the kinetic energy of the car and why the whole continent just exploded...

  • You have the technology!

  • Yes! I have so much anime softcore blocked in my feed haha.

    (12) A great way to find new communities: when you see a user who posted something interesting, click on them and see which communities they're in. Then subscribe to those :)

  • A couple of notes and unsolicited advice as someone who is almost an old hand already...

    (1) Your front-page will be more interesting as you subscribe to more things. You can subscribe to things from other Lemmy servers and they will be pulled into your feed here.

    (2) Communities that are hosted on this server will show up under "Local".

    (3) "All" shows all of the local content from (2), but also any content that this server had to fetch from other servers for others. Basically, when you subscribe to stuff, it'll end up in All for everyone else on this server as well. If no one on the server has subscribed to specific content from another server, it won't show up in All. As a result, All is sort of a cross section of our users' interests.

    (4) If you were to sign up for another server -- say lemm.ee -- you would get a different Local and All. But you should be able to subscribe to the same things regardless of the server you chose.

    (5) Some servers are not connected to others, for reasons. This is called defederation. It's basically a means to block an entire server who has a community not behaving in a way that doesn't jive well on your local server. Lemmygrad.ml is blocked from this server, for example. You probably won't notice, but on rare occasions you can't subscribe to a community on a blocked server.

    (6) You can help the quieter communities grow by shitposting. Throw your backlog of old saved memes into them. There isn't as much traffic here as reddit, and the niche communities often don't exist (or are silent).

    (7) Find a larger community to post to for engagement. For example, on Reddit I would subscribe to the WinnipegJets team sub, but on Lemmy it is too quiet. So instead I post my Jets content to the more general Hockey community so we can have some discussion. This will change over time.

    (8) A good place to find communities to subscribe to is: https://lemmyverse.net/communities -- copy and paste the community name -- eg: !technology@lemmy.world -- into the search bar and then subscribe.

    (9) Meow

    (10) Try different sort options. New or Scales are my favourites.

  • I use old.reddit in desktop mode still, on occasion. Today I clicked on a screenshot of a game cause I wanted more detail. I was directed to the new Reddit interface. I right clicked on the image and chose "open image in new tab" and got the new Reddit interface. I tried CTRL-scroll to zoom in the image, and it made the UI elements larger and in the process shrunk the image. I left the site.

  • The most ridiculous thing here is the assumption that Canadians would ever be more than Puerto Ricans in this scenario.

    (1) We'd only ever join under duress

    (2) If democracy still exists in the US, we wouldn't be given the vote, because we'd vote against them

    (3) If democracy doesn't exist anymore, then whether we are called a state or not is irrelevant

    (4) Canada gets turned into a strip mine with everyone conscripted to go fight against Mexico or whatever Roman Empire-style nonsense follows so that we can't organize resistance

  • Fascism requires enemies, both internal and external. These enemies need to be painted as simultaneously: weak and can be crushed; but also so dangerous that they are destroying the country. Once the population accepts this rhetoric, the government can literally do anything.

  • Did they think they could drive faster than the radar who catch them or something?

  • Or, hear me out, they went public and now they are making their product worse as enshittification takes its toll.

  • Mercury feeling excluded

  • Mine does this too. The combo of the noise of the coffee maker and the smell probably reinforces the routine.

  • This seems to be mostly a problem for publicly traded companies. There are exceptions. But if you look at airlines, the pattern is there.

    They should be considered infrastructure. Infrastructure can pay a dividend to shareholders, but you shouldn't be able to speculate on shares.

  • We could stack export tariffs on there. Bureaucratically difficult since we currently don't really do export tariffs. But it would be an interesting political response.

  • Canada wouldn't be allowed to vote, presuming elections still existed. It's just expansionism at the end of the Republic.

  • I was trying to keep my comment short(ish), but you're not wrong. There are other complications :)

  • What's the weirdest one you've tried? Most challenging? Have you found any really cool defining features in any distro?

    For example GoboLinux and NixOS eschew the Linux file hierarchy standard (FHS), and that becomes their defining feature. But many other distros have some other defining feature. Slackware uses tarballs as package management and oldschool init. LFS has you build from nothing. Etc.

    I use Kate -- part of the KDE project ecosystem (for anyone else wondering) -- on all platforms, including Windows. So worth it.
