  • Their reasoning seems valid - common sense says the less you do something the more your skill atrophies - but this study doesn’t seem to have measured people’s critical thinking skills. It measured how the subjects felt about their skills. People who feel like they’re good at a job might not feel as adequate when their job changes to evaluating someone else’s work. The study said the subjects felt that they used their analytical skills less when they had confidence in the AI. The same thing happens when you get a human assistant - as your confidence in their work grows you scrutinize it less. But that doesn’t mean you yourself become less skillful. The title saying use of AI “kills” critical thinking skill isn’t justified, and is very clickbaity IMO.


  • I think you pretty much just now wrote a landing page, you just need to turn those into links and host that page somewhere.

    Sure, you could create a database or JSON file with attributes of each thing and use React or Node.js to generate the UI, but that doesn’t seem necessary for a need on this scale - when things change just edit the landing page. I’ve been keeping links to my soft copies of D&D books and stuff with a simple HTML page for years, and I’m a web dev. No need to do work the requirements don’t demand.



  • You don’t need to research and choose a server, unless you have personal issues. I get the impression that some people are so polarized they feel like logging into the wrong server would put them on the Wrong Side and make them evil. Some also can’t let go of the corporate media mindset that says domination is necessary for survival, or even that a contest is necessary. I just enjoy the content and ignore the complaints about numbers. The concept of multiple servers might keep some people away if they think they need to understand it, but they really don’t.









  • The punching-through should start at the point of impact, since that end of the pole and that spot on the wall pole both know about the collision at that moment, and then the information travels back through the pole. So I think the front end of the pole would start breaking through the wall immediately, while the information about the impact is still traveling back through the pole. For that reason I think the front end of the pole might end up sticking farther out of the barn than the back end, because it has more time to so it. Would be interesting math, which I’ve never tried to figure out.

    There can’t be infinite deceleration, for the same reason that the back end of the pole can’t instantly know the front end has run into the wall. Deceleration travels back through the length of the pole as its atoms squish up against the atoms in front of them and slow down.

    Interesting for sure!

    There’s a thought experiment about this in most intro classes on relativity, talking about “length compression”. To a stationary observer a fast-moving object appears shorter in its direction of travel. For example, at about 87% of the speed of light, length compression is about 50%. If you are interested in the formula look up Relativistic Length Compression. Anyway, if you are carrying a pole 20 meters long and you run past someone at that speed, to them the pole will only look 10 meters long.

    In the thought experiment you run with this pole into a barn that’s only 10 meters long. What happens?

    The observer, seeing you bringing a 10-meter pole into a 10-meter barn, shuts the door behind you, closing it exactly at the point where you’re entirely in the barn. What happens when you stop, and how does a 20-meter pole fit in a 10-meter barn in the first place?

    First, when the pole gets in the barn and the door closes, the pole is no longer moving, so now to the observer it looks 20 meters long. As its speed drops to zero the pole appears to get longer, becoming 20 meters again. It either punches holes in the barn and sticks out, or it shatters if the barn is stronger.

    Looking at the situation from the runner’s point of view, since motion is relative you could say you’re stationary and the barn is moving toward you at 87% of the speed of light. So to you the 10-meter barn only looks 5 meters long. So how does a 20-meter pole fit in?

    The answer to both questions is compression - or saying it another way, information doesn’t travel instantly. When the front end of the pole hits the inside of the barn and stops, it takes some time for that information to travel through the pole to the other end. Meanwhile, the rest of the pole keeps moving. By the time the back end knows it’s supposed to stop, from the runner’s point of view the 20-ft pole has been compressed down to 5 meters. From the runner’s point of view the barn then stops moving, so it’s length returns to 10 meters, but since the pole still won’t fit it either punches holes in the barn or shatters.

    One of my physics profs had double-majored in theatre, and loved to perform this demo with a telescoping pole and a cardboard barn.
