I'm guessing that some manufacturers just don't want to bother with the setup of their own PoS system, or they find Amazon lands them so many more sales that the alternative upkeep isn't really worth it.
I never said that I know everything and wasn't even thinking about the market at all; I was just concerned about a paycheck-to-paycheck life, especially if you happened to be living alone, but never mind.
If the files are exact copies, then MD5 checks will catch them; tweaking so many files just to bypass this could prove to be too tedious of a process for people to bother exploiting it.
However, people could create scripts for others to mass-download, -edit, and -upload their files accordingly to reduce this tedium.
We all have bills, though. How much do you spend on fast food or other luxuries? What is your monthly income and how much are the hard bills (like utilities)? If you don't mind sharing since we're all anonymous on here anyway, maybe we can figure this out.
You're supposed to rotate mattresses every 3-to-6 months to even out their wear. Alternatively, you can just move the pillow to the other side to not deal with rotation. But given the age of that mattress, it'd almost certainly be healthier to sleep on your back on the floor. Can you get an air mattress? Even that'd be better than nothing.
Likewise (well, I don't know about "hundreds," haha, but dozens, certainly). Ever since tab-searching became a thing (% in the omnibar of Firefox or Ctrl+Shift+A in Chromium), tab count or location in the tab strip doesn't matter; just jump to whatever you need. This has been tremendously game-changing at my work which also calls for dozens of spreadsheets to be accessible at a moment's notice based on the task at hand.
Interesting. Does it take you back to resume if you closed it halfway through a video?
