  • A lot of folks think their decentralized internet forum of choice should be a free for all, but that’s not realistic.

    Moderation and censorship are easy to get confused. Moderation includes reviewing content and sources for quality and safety, while censorship aims to control or manipulate a narrative. (general words taken from this page)

    A PieFed instance defederating from a historically nasty fediverse server or 12 is just a form of moderation, and is up to whoever runs the server. The reason for blocking hexbear/lemmy.ml/lemmygrad could just be to cut down on the amount of manual moderation that’s required by having their stuff federate to your server – not trying to control a narrative or suppress any opinions – just historically lots of wrong, inaccurate, inflammatory stuff that adds to a moderator’s workload. Easier to avoid it.

    Lemmy.ml removing comments and banning people for having opinions that differ from theirs is censorship, because 1) they are very consistent about it and 2) it drives their narrative.












  • This sounds pretty fancy.

    Commercial aircraft get their location from multiple places including GPS, ground based facilities (VOR’s), IRS, etc. IRS is what I’m used to calling it, but it’s the same as INS, which is what this article is talking about.

    It determines location by keeping track of rotation, acceleration, etc. It’s often called “dead reckoning” because it just gives the best guess, and you don’t know how accurate it is. There are multiple of these devices on each aircraft, and they compare their locations to the other sources and if one is drifting way further than the rest, it gets ignored. That’s a very basic explanation because how it really works is way above my knowledge level.

    It’s very cool how these devices find their location, though. When you first boot the system up, it spends about 5 minutes measuring the rotation of the Earth. For this reason, you can’t reset it when in motion. Based on what it feels it can determine your exact location on the surface of the earth.
