So what exactly are 3rd party cookies?
I’m on a.com, that is what’s shown in the address bar.
The page includes a resource a.com/image.png. A request the server will include cookies from a.com. That’s a 1st party cookie. Correct?
The page includes a resource b.com/image.png. The request will not include cookies from a.com; this was always the case. b.com can however set their own cookies. Since we are on a.com, cookies from b.com are ‘third party’. Correct?
It gets interesting when we navigate to c.com and c.com includes b.com/image.png, a tracking pixel we have seen before on a.com.
Without 3rd party cookie protection, b.com sees the cookie they set previously while on a.com. This will now be blocked. Correct?
Now explain this in a Javascript world.
It’s also a way for people who regularly travel less than 20 miles (if this number is correct).
Most device consume more power than you can realiable get from solar on the device. You can’t power a cellphone from a back-mounted solar cell nor run a car from a solar roof alone.
But don’t make the mistake to assume that everyone has (cheap) power at home or that everyone has a (suburban) home. Photovoltaic is cheap and reliable. And you need space, so it makes sense to put solar everywhere.
