From 14 to 31 is still pretty rare. (I checked, population is ~6mil).
And at such a low rate relative to the population, if you're assuming most cases don't report it, the difference in reporting could pretty easily be increased awareness that reporting it was an option or some other similar cause unrelated to an actual increased failure rate.
Just FYI, this is only the additional "live books" thing.
The actual books are all there as normal downloads.
You shouldn't be taking ownership of files and then deleting them without communication a hell of a lot better than that.
I understand what happened. I'm saying that if you're going to delete stuff that was there before the software was, your flow to adding a project should include suggesting a base level commit of everything that's there already.
I wouldn't assume "discard changes" means "delete files that existed before the editor did".
But you can get an Android device with a reader that's actually functional. Navigating a file system doesn't even vaguely resemble functional.
I'm not advocating stock Kobo. I'm saying the absolute bare minimum for me to consider a reader usable at all is the ability to navigate/search/filter my library by all of author, publisher, tags, series, and any other metadata. Folders are an extremely poor substitute for actual organization tools.
Oh I know you weren't bashing him. I was agreeing with your point that he's super talented.
For the whole planet? More than your computer can hold, most likely.
It's 80GB/hour at high quality and that's a very small area of the planet.
Apparently some people hate them just for him, but I really enjoyed his narration of Ready Player One and John Scalzi's Interdependency series.
I used to read the Hardy Boys, Nancy Drew, Chronicles of Narnia, Artemis Fowl (earlier boxcar children).
I never really got into them, but Terry Pratchett's Discworld books are really popular. My friends around then liked Animorphs.
(It's hard for me to judge reading level super well because I was always pretty ahead of my age group, so take it with a grain of salt.)
Another suggestion is find a local library and just wander the kids section with them. They should have stuff managed by approximate age level and you should be able to find stuff that way.
I'm genuinely baffled every time I see people suggest KOReader.
It has the worst library navigation I've ever seen.
The hard math is figuring out the path (because small imprecision in the guessed location of the object over time can pretty easily cause meaningful errors. If you control the engine and know the real vectors, projecting their path out isn't super complicated.
But I'm all for the idea that knowing a variety of math allows you to solve a lot more problems.
