I dare fear that you may be the exception rather than the rule.
Most people probably just frame their picture based on the screen.

How many people actually use any significant amount of (ditigal) cropping?

16MP images scale down much nicer to 300x400 pixel facebook pictures than 13MP images.

Even with an amazingly good lens very few people actually need 16MP on a phone (or can even visually distinguish it from a ~4MP cam).

I don't know about the US education system, but in the Netherlands, grades are only valid for a limited number of years.
"Completing the degree" would mean having to do every single cource anew. "Missing parts of the degree" would be every single part of the degree.

I thought Zuckerberg only dropped out of school AFTER it became clear Facebook was going to be succesful.

A push does not remove anything from history, nor does reverting a change or removing files.
Git has no "official" way of completely removing something from a repository.
Once something has happened to a repo, it can always be traced back.

The subtle difference is that serial killer victims aren't actively involved.
Hula-hooping women have a choice to stop hula-hooping.

Also, I'm pretty sure if some attractive, half-naked guy was hula-hooping, women would stare as well.

In the end, Git is just a large amounts if bits.
So "yes", it can be manipulated.
It's not some easy database though; removing something from a Git repositiory without leaving a trace is very, very hard.
Git is also distributed, so it seems quite likely that there are many copies of the repository everywhere, including in her posession.
Each would have to be changed very meticulously in order to not look suspicious upon investigation.
It's not impossible, just something completely out of scope of anybody except the few people who fully understand the inner workings of Git.

OTOH, she only started badmouthing after she was being publically badmouthed.

Having a strong believe implies involvement with religious activities.
I can understand why GP interpreted it as such.

The two don't need to exclude each other.

Create a user interface that can do everything without javascript and without any flashy graphics, then add some CSS stylesheet to make it look nicer and flashier and add javascript to add more convenient ways of doing what you could already do without.

For example, take a classic list ordering GUI with up/down buttons. Works fine without javascript. Add javascript to make it also do drag&drop. It works better with javascript, but still works just fine without.

Web interfaces can gracefully degrade down to a very low level.

"I'll update the documentation to match the implementation".

I will celebrate this fact by eating a very slighly inaccurate pie this year.
Next year though... it's gonna be perfect!

Make it a hybrid.
On it's normal trips (like 99.9999% of all trips) it could run 100% electric.
Whenever there's a shooting, switch to internal combustion.

Their current device is basically a ruggedized Android tablet; there are plenty of those available in toystores for less.
With regards to hardware and OS, they've gone as far as they can and the market has taken over.
They should focus on distribution to poor countries and the application side of things (which seems to be exactly what they're doing).
