my dumbass: actually, did you know that the sun outputs 3.83×1026 W? that's so much that the energy output by the Sun in just one hour could power the Earth for about 56.1 trillion years at the current global consumption rate. Or, if you ....blah blah blah something something Kardashev scale....
it's not a logistics nightmare, we used to do that until plastic gave us the idea of single use containers, many restaurants still do it with larger 1L bottles
also, while yes glass does have a really high melting point, most plastics never get recycled and instead get burnt, releasing a lot of toxic chemicals in the air (and even if they weren't, you can only recycle some types of plastics, and even if you did, new objects can be made only by some percentage of recycled plastic, and never 100%)
FYI cans have a plastic liner to prevent acidic foods from dissolving the aluminium, so there's still some plastic in it (much less then fully plastic bottles tho)
right, you fan disabile them using their unique software which you have to install for every component, signing away your life (cough cough Disney) in the process
TL:DR cloudflare made a new recaptcha which does some complex math and other stuff on your browser, which done once has no noticable effect but if someone were to scrape websites at an absurd speed it slows everything down significantly.
this is not only cool because you don't have to manually solve the captcha, but also because it allows for low-speed scraping to be feasible, with tools like flaresolverr
and you'd be right. If you are sure about it, and you know how it works, just make it yourself, so that you don't need to put anyone else in danger of getting sued.
The reason hardware stores don't sell them is that people WILL use them in a dangerous way, and they don't want to be held responsible.
in AC, which is what home electricity uses, the polarity is constantly switching, from + , then - , then + , and so on, 50 or 60 times a second depending on where you live. This means that, unlike batteries, it's symmetrical, and you can just splice the cables and attach two male plugs together and they will work regardless, even if you somehow attach the neutral to live and live to neutral, in fact in many countries you can actually buy just the plug without the cable and then you can assemble it yourself in whatever way you please.
of course tho, this should be done only if you have a decent understanding of electricity, and it should not be attempted by someone who lacks those competences, hence why hardware stores "gatekeep" male to male plugs. If you really need one and are sure you understand how they work, you can probably make one yourself.
could also check for urea content, or proteins, but sure why not drink it
