    From the article …

    This effectively means that, if you get banned by the Bluesky company, you’re out. Sure, you could still host your own Personal Data Server, wait for a non-existent independent Relay to fetch your data and interact with users of third-party Bluesky applications. But you won’t: you’re effectively at the mercy of the Bluesky company.

    Point two, and more importantly: this approach provides an “exit strategy” in the event that Bluesky “goes evil”. Right now, that’s false: parts of the social network are still centralized and it’s impossible to avoid that. But even if we limit ourselves to PDSs and Relay, the current situation is that federation is only achievable in theory and no one has done it in practice yet.

    It’s in the post: https://explainxkcd.com/3064/

    Thanks, I missed that the link was in the post.

    And it’s quite funny if you happen to have some programming background. If not, you tell me.

    I am a software developer, and I just didn’t get the joke at all, even after reading the explanation…

    The comic relates this to a common issue when editing documents or coding, where the author accidentally makes changes to two separately created versions of documents, when they meant to only edit one, which can result in changes to both (or all) resulting documents functionally essential parts of the completed project

    Honestly not trying to be pedantic, joke just flew over my head I guess. 🤷‍♂️

    So if you put earth into the Oort Cloud it would still be a planet, because we know that earth has the potential to clean it’s neighborhood.

    Would it be a non-planet for the millions of years it would take to clear its orbit?

    Does Earth’s body/features magically change somehow for the duration of the clearing process, so that it doesn’t resemble a planet?

    The point is that using external criteria to identify what an internal thing is is not logical, or scientific.

    The theoretical object in the Oort Cloud would relative fast clear the space around himself if it had the size to have a stable and long living internal heat source.

    You don’t know that, especially with the size of the Oort Cloud, and the size of the orbit to clear. And the rules for how much clearance has to be done is very arbitrary.

    Also bodies can be small and have a decaying heat source that’ll last many millions of years, or renewing heat source via tidal interactions. It’s not necessarily a size thing.

    Ceres does appear to be active in some form with cryovolcanoes, based on the 2015 Dawn mission.

    Then It’s say that it was a planet, though IANAPG.

    I think focus ought to be more on what the qualifications are for the minor label. What does it mean to be minor?

    There shouldn’t be a ‘minor’ nomenclature, it’s a contrivance. It’s a planet, or not

    Also, to reiterate, the issue being discussed is one of disqualification, and not what qualifies. Identifying a body as a planet or not should not be done based on the criteria of the crowded or not nature of the space around it.

    For some reason this subject always hits a nerve

    Always bothers the hell out of me because of the politics that went into defining an arbitrary rule that makes no sense for identifying something that the rest of humanity has to obey, as well as that planetary scientists did not make the decision astronomers did, as well as that just a small subset of the international governing body voted the rule in, and not most/all of them.

    Scientists should know better. They should not ‘just call it a day’ then make money by arrogantly selling books on the subject.

    It’s bad Science.

    They should have used the term “dynamical dominance”, implying whether or not a body is the primary object left in its orbital area after formation. And this has its own issues, as solar systems change over time.

    What does the environment around a body have anything to do with classifying the body itself? How would the body magically change if the area around it became crowded? It’s a nonsensical criteria.

    Things can get defined separately from themselves. And they can be defined to be several things. I’m a Norwegian and a German because of my parents.

    Your political nationality doesn’t stop classifying you as a human being.

    Being a world is different from being a planet.

    You completely avoided the point I was making, that a body doesn’t stop being a planet because it’s neighborhood/orbit is crowded.

    If the Moon got too close to Earth so that it broke up (Roche limit), so that now Earth has not cleared the space around it, it would stop being a planet for a million years or more until it “cleared out” it’s local space/ orbit, based on the rule that disqualifies a Pluto from being a planet.

    If you pick a random Earth-sized lump of the Sun as a potential planet, and swap its place with Earth, Earth would quickly get mixed in with the rest of the Sun and stop being a distinct entity, so be very silly to still call a planet,

    Why? Everything about Earth is still the same, skies, oceans, etc. Only difference is that it’s crowded in by other bodies now.

    Trying to scientifically judge if a body is a planet by something external to it, if it’s being crowded in our not, it’s not logical, and doesn’t change the body itself.

    What does a body clearing is orbit or not have anything to do with the body itself?

    Location makes some difference to whether or not something’s a planet.

    Only because a very few human beings astronomers illogically/arbitrarily decided that’s so. The reality on the ground for the body is that its still Earth, the planet we live on.

    Planetary Scientists should be deciding the rules, and not solely Astronomers.

    I realize the comic is good natured, but I feel the need to be serious for a moment, and say something…

    Any rule that would disqualify Earth as a planet, if Earth and the other planet switched places, it’s a bad rule, and should not be used.

    Humans don’t stop being humans, if they are standing alone one day, and are surrounded/crowded by other people the next day.

    Also, having a single handful of people decide for the species what the definition of a planet is, and then some of them sell books about it, it’s not good science.

    Planetary Scientists really need to step up, and decide this.

  • Was quick browsing for openwrt and found the banana pi r3.

    One thing that surprised me when I was looking to upgrade my old router ith OpenWRT is if a firmware for your router supports ALL of the features/hardware of that router. In my case, Wifi support was not supported, so I had to disregard using OpenWRT as a choice.

    So be sure to look carefully at the firmware that you find. I personally had just thought that if a firmware exists for your hardware that all of the major (but maybe not minor) features would be supported, and that is not always the case.
