Where in the fuck do they force cashiers to stand? Is this some kind of American bullshit? Why would they do that.

Pi Hole couldn't block YouTube ads last time I tried it, which is one of the main things I want to have adblock for. So I went back to ublock origin.

So, yeah, bottom line: you only need a delta-V of about 12 km/s to get out of the solar system, but a delta-V of 30 km/s to get to the sun without going into orbit.

This is true, but the possibility of gravity assists mostly nullifies the difference. If you can get out to Jupiter you can basically choose: either let it sling you out of the system, or let it cancel out all your orbital velocity so you fall into the sun.

These are all technically correct but fairly inconsequential. Even just to graze the sun you need to lose 90% of your orbital velocity. And although everything orbiting the sun will eventually fall in, the friction is really low. It will take billions of years to lose enough velocity to fall in.

The problem isn't even the hard drives, it's how they are managing them. There's not many digital data storage solutions around that you can dump into a closet for a few decades and then still read.

You have to regularly test your hard drives, so that when one fails you can take your other copy of the data and put it on a new drive.

Efficiency records involving perovskites are generally not that interesting without any longevity data. As far as I'm aware, the lifetime of current SotA perovskite solar cells is measured in weeks or months. That's not commercially viable.

Not that efficiency research is completely useless, but the longevity is the real challenge that's holding this up.

I'm confused now, because espresso is also coffee? Like, it's all made from coffee beans. I agree that Americano is espresso with water, but to me that is absolutely a kind of coffee.

I guess I've never really thought of "black" as a type of coffee. Where I live black usually just means you don't want any milk in whatever type of coffee you ordered.

an Americano is not a black coffee.

It is however, coffee that is black,

Hold on now, I'm not getting this. What meaning could "black coffee" possibly have other than a coffee that is black?

So that's hot water that went through pressed coffee powder.

The "pressed" doesn't refer to the coffee powder but to the water: the water is pressed through the coffee grounds using high pressure (around 9 bars or so).

Nah, that's mostly stock options, so it doesn't come out of the revenue. His cash salary was only a couple hundred thousand.

It's probably better from a tax point of view. Plus he's planning to cash out big on his own IPO, so he prefers the stock.
