Yes. Usually you have a brightness and sometimes also a proximity sensor. Proximity is usually used for phones so they can deactivate the screen if you hold the phone like an actual phone against your ear.
Is SQL an API contract using JSON? I hardly think so.
Java does not distinguish between null and non-existence within an API contract. Neither does Python. JS is the weird one here for having two different identifiers.
Why are you so hellbent on proving something universal that doesn't apply for the case specified above? Seriously, you're the "well, ackshually" meme in person. You are unable or unwilling to distinguish between abstract and concrete. And that makes you pretty bad engineers.
If there's a clear definition that there can be something, implicit and explicit omission are equivalent. And that's exactly the case we're talking about here.
I find it really weird that something as simple as the basic functionality of nextcloud seemingly can't be implemented in a stable and lightweight manner.
Nextcloud always seems one update away from self destruction and it prepares for that by hoarding all the resources it can get. It never feels fast or responsive. I just want a way to share files between my machines.
There are other solutions, I know, but they're all terrible in their own way.
That's exactly not the thing, because nobody broke the contract, they simply interpret it differently in details.
Having a null reference is perfectly valid json, as long as it's not explicitly prohibited. Null just says "nothing in here" and that's exactly what an omission also communicates.
The difference is just whether you treat implicit and explicit non-existence differently. And neither interpretation is wrong per contract.
Well, I ditched my old phone because the battery is practically dead.
And my point is not, that I don't have a mitigation at hand, but it's stupid that I even need that mitigation. Essentially, the security providers offloaded their incompetence and/or unwillingness to pay insurances onto all of their users.
These "jobs" are just a way to acquire talent. A larger company can almost always need a few more "good workers". So if a really good candidate comes along, they'll snatch that person, if the candidate is just okayish, they tell them someone else got the job.
Interoperability is only required, if you have a significant market share. Apple does not have this in the EU. iMessage specifically doesn't fall under this regulation, since hardly anyone uses it.
And since Apple plans to publish an SDK for their intelligence anyway, you can't really regulate them for being too closed.
So either that's a purely political retaliation, or their "super privacy friendly" services aren't as privacy friendly as they claim.
We had something like this too. The header had our company's logo as just a rectangular white picture. It looked like someone just copy/pasted the first result on Google images.
That's software development for you. Why is that weird value there? Because some guy, at some point, had checked for that and somehow it's still relevant.
I know of a system that churns through literally millions of transactions representing millions of Euros every day, and their interface has load bearing typos (because Germans in the 90s were really bad at the Englishs).
If you actually want to learn maths (that is, if you're not just venting), you could try to ask for help in dedicated math or teaching communities.
The problem with teaching stuff you know, is to put yourself in a position of actually not knowing anything. I'm a software developer and had to teach some apprentices a few years ago, and it was really eye opening to me to see how much assumptions about the apprentice's knowledge I made even though I thought I made my explanation "basic".
It's quite possible that all the tutorials you've read are either for literal children, so they just don't work for your adult brain, or they're intended for adults and assume too much.
On a personal note: how did you get into that situation? Were you home schooled?
Yes. Usually you have a brightness and sometimes also a proximity sensor. Proximity is usually used for phones so they can deactivate the screen if you hold the phone like an actual phone against your ear.
