The idea that writing in assembler results in faster code than compilers is a fallacy. The compilers are generally better at writing in assembler than you are, and know more tricks regarding moving data to word boundaries and stuff like that.

You are just foolish. Scientific computing does not require the fastest CPU or largest computer. And in addition to computing stuff many like to use visualization tools to analyze them. The mac is convenient for both applications. I generally use a Ryzen CPU with nvidia graphics but lots of people use mac for the same functions. Using the exact same programs I use on Linux.

And the function of an os is indeed to manage running programs and organize files.

The CPU is great for scientific calculation. The os is just a thing that manages running your programs, it isn't a religion.

The filings list many possible risks to avoid future lawsuits. They generally include stuff like "customers may cease to buy our products" and "competitors may be more successful" among others.

I always turn mine off in Firefox, and never notice a performance difference. Is there an analysis of how much caching affects performance? Sometimes I think it is only there to enable LEO to analyze what you have been browsing.

Yes. And I didn't read that anyone is deleting the originals so why are they whining about this.

In the olden days all we wanted the operating system to do was run our programs. Why does it need to be all the programs as well? Seriously, do OS's really need more features than they already have?

Isn't the point of the first amendment to protect expression of ideas that the government doesn't approve of? Facebook itself makes very few statements. It is 'the people' who are using Facebook to express themselves.

"but if schools require kids to have Facebook"

"if" - I haven't heard of schools requiring social media "to stay informed" where is this happening?
They should stick with requiring the National Inquirer.

The FDA and Dept of HHS uses naval rank structures and are not involved in warmaking. Lay off the coffee.

Even electric cars require significant oil for lubrication. Not in the scale of fuels but still required.

Just generate a random uuid and change a few digits.

This is a one time thing, not a sequence. It is unlikely one could use any information on your computer and it's environment at the moment you made the key to find out what our was. And even if that were the case you can foil it by changing a few characters after generation. Just Genesee

The Apple legal staff apparently needs to generate more billable hours during this COVID time.

There is no shame in using robust technology that meets all requirements of the specification.
Advantages:

Floppy technology/versions is now static. No need to worry about the "new version" breaking the system.
Software can assume the storage capacity of the device, because it is fixed.
System is fully tested with this technology over the past 20 years, all behaviours and failure points are known by now

There is no point in changing unless the requirements change. For example if the data size cannot fit on the disks or the time requirements for loading speed or something is changed. The IBM AP101 works great on space shuttles, missiles and all kinds of things. Not the fastest, but has been proven to work in those environments.
