That's not how it works. You're correct when you say that from your point of view it's Earth's clock going half speed and from Earth's point of view it's your clock going half speed while you're traveling away from Earth (or Earth is traveling away from you, both are equally valid), but that's only true as long as the distance between you and Earth continues to increase at 86% of the speed of light. As you decelerate at your destination your reference frame continuously changes until you're back in the same frame as Earth (or nearly so, we can assume the two stars aren't exactly maintaining their relative positions). While you're decelerating, from your perspective Earth's clock speeds up and goes faster than yours, how much is determined by your rate of change in relative velocity. Earth's reference frame isn't changing (ignoring movement around the sun, galactic center, the great attractor, etc.), so the Earth's perspective on your clock doesn't change, the Earth sees your clock gradually speed up as you "slow down" until it's going the same rate, but never faster. So once you're back in the Earth's reference frame both you and the Earth will agree that your clock advanced 5 years while Earth's clock (and your destination's clock, adjusted for any relative movement between it and Earth) advanced 10 years. This assumes a constant 86% light speed and ignores the time accelerating at departure and arrival so let's assume very fast acceleration so it doesn't change more than a couple days.

Edit: this is all completely ignoring gravity based time dilation from the spaceship climbing out of Sol's well and going down the destination's well and only considers velocity based time dilation. It would be more correct if you only considered two spaceships in a void where one accelerates to relativistic speeds and then accelerates back into the reference frame of the other.

Let him build it.

Let the chauffered car thing fail.

Eminent domain the tunnel.

Stick a fucking train in it.

I have a question about this I haven't been able to answer.

Is the problem the "flushness" or the lack of mechanical linkage to the door latch?

I've been in several Teslas, every model but the Cybertruck, and you push on the fat part and the skinny part comes up, which you pull to open. But as I understand it, that just activates an electrical servo or something that unlatches and partially opens the door, and that's the problem because without power pulling the handle does nothing.

I had a Jaguar F-Type R (I think Range Rovers have the same handles) and it had flush handles that you could set to pop open when you approached, or you could hit a little button on the forward end to pop open the rear end or, like the Tesla, you could push on the forward end to manually raise the rear end and when you pulled on the handle you were mechanically unlatching and opening the door, unlike the Tesla. You could disconnect the battery and still open the door, which as I understand it, you cannot do with a Tesla. Would this be ok?

If it seems far fetched that every news organization keeps talking about flushness when that's not the problem, I'm willing to entertain it because that's what happens every time my area of expertise ends up in international news. Whenever my profession, or a related one, is in the news they almost always get it at least a little wrong, and sometimes ridiculously wrong. And they say the same wrong things across all news sources all over the world. I, and others in my group of professions, can see why this happens. They get some basic information but lack context so they interpret it wrong and what comes out is complete nonsense, or at least a little misleading.

I thought I was a "customize everything" Nova launcher kind of guy, but when I heard the original developer had quit the company that bought it I switched to Niagara. I thought I'd just try it out for a few days, immediately got hooked. Just a few things to set up then your done and getting to everything is so much faster and easier, one handed.

Not just anyone, but it's not too hard. They expect to be able to get you into shape. There are also waivers available for disabilities, if you score high in the ASVAB you're more likely to get one. OP didn't mention any disability so it shouldn't be a problem.

And different branches have different requirements. A buddy from high school with a horrible home life and no prospects was too heavy for the Marines but the army took him. Got a specialty with transferable skills in the real world and has a great life now. In and out before 9/11 though.

20-30 years ago they were awesome. Used to be around the speed and price of five guys but way better. They've been on a steady decline for a long time now. All of them near me have been shut down for a while, I'm kind of surprised they're still around in any significant numbers.

Say you lost your driver's licence/ID and need your birth certificate and SS card to get a new one, a new passport is easy enough if you have those basic documents.

I'm going to get burned like crazy for saying this but if leaving right this second, like NOW, really means homelessness for you; go join the air force. Sign the papers, pack up what they let you bring and forget about everything else. If your family gets wise to what is going on and tries to stop you, they will come looking for you and your family will be in deep shit. Maybe even mention to your recruiter that if you don't show up at the appointed time, you're probably being held against your will, might speed things up.

There's another catch if you're not using a card with rewards. (As I understand it this is mostly a U.S. thing, other countries don't do this.)

Every year when I take my big vacation my wife and I get 1-1.5 of our international business class tickets paid for by rewards on one card and about half of our hotel suites (about 10-11 nights) paid for by rewards on another card. If you're paying cash or using a card without rewards, you're paying for my vacation.

Places with different prices for cash and cards are vanishingly rare. Mostly because card processing companies try to penalize places that do this. So everyone pays higher prices to pay for the higher processing fees for reward cards. If you aren't getting something back you're just paying for people that are.

I just scrolled past three depressing posts because I didn't want to deal with it this early and clicked a comic instead, only to have it be this comic.

That's funny, I had the opposite experience.

I used to count on my front page of Lemmy to give me links to stories about Gaza that I wasn't getting from the major news outlets. Every page had multiple posts about Gaza with stories and context I sure wasn't getting from Reuters.

After the election they quickly became few and far in between. With most of them things I have heard about elsewhere, the Lemmy post only being good for discussion.

The problem with GMOs isn't the GMOs themselves, it's why they've been GM'd. If they've been modified to be "roundup resistant" so they can dump a truckload of glyphosate on them, or something similar to that, that might be a problem.

If I'm buying fresh produce it's not a problem, I can can make double sure to wash it properly. But if it's processed food, I definitely do not trust food manufacturers to get all that shit off the vegetables.

Looking for GMO free canned fruit/vegetables, frozen fruit/vegetables, or anything with fruit/vegetables in it is, in my opinion, a good idea. But a fresh cucumber? Just wash it.

I'm disappointed those links aren't real.

 

I apologize in advance of this is too basic a question for this community.

I just learned about lexisnexis and went to their website to request my report, opt out of everything I could, and request my information be deleted.

Are there any other companies like this I should be aware of so I can make the same requests there?

If it matters, I'm in California and it's my understanding that I have a few more rights concerning this sort of thing than some others do.
