Your legs are moving but your head / vestibular system isn’t experiencing acceleration that it expects with those leg movements. Think of it this way, if you are holding a pendulum and take a normal step forward, the pendulum will start to swing. If you take a step forward on the magic floor tiles, your legs move normally but since your body stays in the same place, the pendulum is motionless.


> Your legs are moving but your head / vestibular system isn’t experiencing acceleration that it expects with those leg movements

That's also true on a treadmill. I think the bigger problem would be that the world appears to be moving (unlike a treadmill) and you don't feel any acceleration.


So can I use the Disney system to simulate running on a treadmill?


You don't get motion sick on a treadmill because you're not wearing a VR headset. There's no forward motion of your head captured with your eyes to mismatch what your vestibular system is feeling.


To add to your point, there is a somewhat unpleasant sensation once you get off the treadmill, i.e., even if you are standing in place, it feels like you are moving forward.


This reminds me of the similar weird sensation of phantom movement after jumping on a trampoline.


I actually do get a bit of motion sickness when I get off a treadmill. It takes me a couple minutes to get my bearings after stopping.


This is incorrect. You don’t get motion sick on a treadmill because the small accelerations and decelerations match what your eyes are seeing. There is motion.


I agree there's motion, I'm saying there isn't a mismatch with what your eyes are seeing, which is what causes the motion sickness


But on a threadmill you're going in a straight line and usually at constant speed. A constant speed, you don't have acceleration.


Exactly, you don't have acceleration, and the world around you isn't moving relative to you, so there's no mismatch.

The treadmill shows that performing the walking movements without acceleration doesn't generally cause motion sickness.


> you don't have acceleration

If you actually use a treadmill, or watch motion capture, you’ll see that this isn’t the case. It’s a lot of slight accelerations and decelerations. The variation change from person to person, and more experienced runners are able to minimize them, but they’re still present.

> It’s a lot of slight accelerations and decelerations

Isn't that always true? If I pay attention to it, I notice a lot of tiny movements of my head, as I just sit here typing.

"You don't have acceleration" is just talking about the big accelerations from 0 mph to roughly 3 mph to 0 mph, not implying that you're completely motionless as if frozen in ice.


Acceleration is change in velocity and change in time, either can effect the apparent amount of acceleration. The velocity you accelerate to or from is just an implementation detail.


The article says its SSMB which is a hybrid of synchrotron and a linear free electron laser. https://www.quora.com/What-is-a-Synchrotron-SSMB-generated-E...


A self replicating supply chain is obviously the basis for success and scalability of the ‘replicator program’.


I've been working on a little project that uses D1 and have been hoping that is how D1 will evolve. A db per customer in my case. Is the colocation in a durable object so 'business logic' and sqlite can live in the same isolate for performance and security? Would that be a post 'out of beta' feature? Ive been building as a monolith thinking that the number of databases in the alpha was indicative of the future.


I grew up in Oxford, MS. circa 1980. Kudzu didn’t blanket the roadside landscape at that time. It does now. Every time I go back, it is the blanket over everything. I love the flowery language of the article (takes me back a bit), but it really has overtaken the landscape. If you grew up there, you know.


Unrecorded phrases from the approval meeting.

It looks 'sturdy'.

I didn't know they made LEGOs at this scale.

I knew ChatGPT would affect a lot of professions but I didn't think it would be this fast.

Future proof, It blends in seamlessly to the Bladerunneresque environment we imagine the future will look like.

We already removed all the 'slack' from the project.


They have a business plan that is predicated on people signing up for a service that they want to use but don’t and fail to unsubscribe because it’s like giving up on reaching their perceived potential best selves. It’s simple.


The gyms could still offer online cancellation and continue to make bank from this behavior if they sold you a contract with a minimum term, and heavy cancellation fees if you try to cancel early.


Daleks!


My team is 100% remote and we work with other teams that aren't. We use Google's Jamboard. All members of my team have iPads and 'pencils' and there is a dedicated app, and our conference rooms have special Jamboard devices mounted on our walls. It can be used from a browser too. They all work pretty seamlessly together. I don't work for google but I like Jamboard.


Sounds like a lot of hardware expense for something that could very well disappear.


You don’t need Jamboard hardware to use the web app version: jamboard.google.com


Shrug? I can’t remember the last time I needed source forge. What is there and why is it important to preserve that business model? I’m genuinely curious.
