There's also https://sendfiles.dev/ for browser to browser transfers. You could also self-host an FTP server (or something more modern like NextCloud) and open a port on your router to let users download (and take it a step further with a dynamic DNS provider in case your IP changes). I agree that it shouldn't be this hard just to transfer a file.
Serious question for you. Have you read any recent papers? Some quantum computing applications have outperformed classical computers already[0] and will get better with more qubits and less noise. This stuff is in its infancy and making small baby steps. The phone in your pocket didn't get here without punch card programming or computers the size of rooms. This is that and you're around to witness it. Have some patience!
Searching Twitter for examples of people decrying "Chinese virus" can come across as confirmation bias. It's also not an accurate measure of how many people truly disapprove of the name. The point is that the argument for or against it is frivolous. As for speaking in codes, you could just call the virus by its actual name, SARS-CoV-2 and the variant G614[0].
Honestly, I think it's a deflection from calling it the UK variant. Calling it the Chinese virus or the South African virus can be perceived as having racist overtones and could also imply that the disease was caused by being simply being Chinese or South African. This could offend someone of said origin, offend someone on behalf of people of those origins, or not offend someone at all. Your next question is probably, "Why was it okay to call the 1918 pandemic the Spanish Flu?" I imagine that in the present day, it wouldn't be okay. We now live in the age of social media, where the opinions and feelings of a small vociferous population can be misconstrued as those of the majority. A no-win scenario then ensues i.e. a culture war. Those who are offended will undoubtedly express their opinions and attempt to publicly shame those who insist on using the name. Those who believe their free speech is threatened or simply wish to agitate the opposition will spitefully continue to use the disputed name. These arguments distract from the real problem at hand: a pandemic.
Anecdotal, but the same happened to me. I later fixed it by running for 30 minutes 3x per week, and continue do to so to this day. LDL, HDL, Triglycerides, and blood pressure are all in the healthy ranges. 5.5 years and counting, with no "cheat" days either.
How is it different from a Newton-Raphson approach, which requires you to make an initial guess as it iterates through several derivatives to get to the root?
