Because motion along the x-axis (left-right) is a body rotation about the gravity vector. y-axis motion is not.
We are upright beings in a gravitational field, so if we see a berry to the left of our visual field, we turn our whole body to face it. Then we walk towards it. We do this from a first person vantage only. We don't see our own backs - just the world itself.
But if a berry is above our visual field, we can't rotate our body that way. That would make us fall over. We instead remain vertical to gravity and rotate a third-person thing. We tilt something else like an arm or stick in the direction. We see this from a third-person vantage only. We see the back of the arm, or back of the stick. If the berry is up high, the part of the stick closer to us is down low. We see the inverted end moving, so it becomes intuitive. Of course, you can focus on the far end of the stick and get a non-inverted intuition too. But this is only possible from a third-person view which we don't often get when our bodies so easily rotate about the gravity vector.
I feel that Rust increases security by avoiding a whole class of bugs (thanks to memory safety), but decreases security by making supply chain attacks easier (due to the large number of transitive dependencies required even for simple projects).
On Android, in Settings, Network & internet, Private DNS, you can only provide one in "Private DNS provider hostname" (AFAIK).
Btw, I really don't understand why it does not accept an IP (1.1.1.1), so you have to give an address (one.one.one.one). It would be more sensible to configure a DNS server from an IP rather than from an address to be resolved by a DNS server :/
> So if you want to use DNS over HTTPS on Android, it is not possible to provide a fallback.
Not true. If the (DoH) host has multiple A/AAAA records (multiple IPs), any decent DoH client would retry its requests over multiple or all of those IPs.
Does Cloudflare offer any hostname that also resolves to a different organization’s resolver (which must also have a TLS certificate for the Cloudflare hostname or DoH clients won’t be able to connect)?
DoH hosts can resolve to multiple IPs (and even different IPs for different clients)?
Also see TFA
It's worth noting that DoH (DNS-over-HTTPS) traffic remained relatively stable as most DoH users use the domain cloudflare-dns.com, configured manually or through their browser, to access the public DNS resolver, rather than by IP address. DoH remained available and traffic was mostly unaffected as cloudflare-dns.com uses a different set of IP addresses.
> A cross-organizational fallback is not possible with DoH in many clients, but it is with plain old DNS.
That's client implementation lacking, not some issue inherent to DoH?
The DoH client is configured with a URI Template, which describes how to construct the URL to use for resolution. Configuration, discovery, and updating of the URI Template is done out of band from this protocol.
Note that configuration might be manual (such as a user typing URI Templates in a user interface for "options") or automatic (such as URI Templates being supplied in responses from DHCP or similar protocols). DoH servers MAY support more than one URI Template. This allows the different endpoints to have different properties, such as different authentication requirements or service-level guarantees.
Yes, but this restriction of only a single DoH URL seems to be the norm for many popular implementations. The protocol theoretically allowing better behavior doesn't really help people using these.

By making the Back button larger and more prominent instead, participants would be able to spot the button four times faster. I suggest to reduce the size of the Send button.
As a non-native Ensligh speaker, I asked ChatGPT what the ER acronym means: Emergency Room (I guessed E was for "Emergency" after reading your story, but I didn't know about the 'R').
AI is also helpful to parse the story about how AI is helpful.
I'm French too, and when I was young, I learnt the Basic language before learning English (by reading Basic programs already available on our computer).
So I was able to write FOR … THEN … ELSE blocks without even knowing what the keywords meant (I just know what they did to the program). One day, I explained to my father what I was writing, and I read out loud FOR … "TEN" … "ELCE" (with a strong French accent), and he corrected me by pronouncing the words correctly ("FOR … THEN … ELSE"). I was shocked: "how do you know?" (he knew nothing about Basic or even programming).
I learnt that day that "for", "then" and "else" were not just keywords in the Basic language, but they were actually real words in English.
