Generally speaking, if Ubuntu works, LMDE will work as well. Unless you have something that is brand brand new with drivers only located in a bleeding edge kernel, you shouldn’t have any issues.
I have LMDE on an old XPS17 and it actually worked with less fuss than standard Ubuntu, mainly because of compatibility with a truly ancient wireless chipset.
I run calibre off my desktop. You can enable the Calibre content server and it can serve up your books for download (or provide a web reader).
If you have an Android device, you can use something like Moon Reader (or any other reading app that supports epub or Pdf) to download content from the Calibre content server.
With respect to covers and metadata, Calibre can tag and fill in this info as well - out of the box it will scrape information from Amazon.
Mr. Clean Magic Erasers.
The “generic” name is melamine sponge. These work exactly the same and cost a fraction of the brand name.
Technically no. The tolerances should be more or less the same (generally 90%-110% label claim for the active ingredient) . Manufacturers aim for 100% and generally hit that target (or get very close to it).
The bioavailability could be different though - if you are doing a bioequivalence trial for generic VS brand, the generic would have to be between 80% - 120%. This difference is generally a result of the starches, fillers, and other stuff that may be in a generic formulation.
Same net effect as your comment (wider tolerances), but there is a bit more nuance.
This 100%. I only figured this out 15 years after having started driving.
To add to this I tilt my rear view mirror (the one connected to the windshield) a little bit upwards to force me to sit a bit straighter and taller when I look at it. You slouch less so for long car trips your back ends up feeling a bit better.
