It's gotten to the point that the moment I see "Rust" and "TUI" together, I immediately assume it's vibe coded. The combination just seems to be vibe coders' favorite, for some reason.

The myth of DNS “propagation” needs to die. Changed DNS entries do not “propagate”. The old cached DNS entries in DNS resolvers simply expire, in an arbitrary order.

There is no such myth that I'd be aware of, and I seriously doubt the author behind this would be operating under such a misunderstanding either. Maybe you used to at some point, but then that's a separate issue.

Propagation is just an incremental spread across a topology. Doesn't need to be a physical topology whatsoever.

It may seem like this program suggests a physical propagation as far as its elevator pitch goes, but one glance at the readme clears it up pretty quickly that that's not actually the case.

Changes do propagate, and seeing funny blinking lights on a world map is cool. Doesn't mean there'd be an intent to convey the process as a geographical spread.

Quite mixed on this one given that the author has experience with Rust before coding agents and this is just his toy project.

There is going to be a time where these vibe coded projects have silent bugs, vulnerabilities or unnecessary performance issues and the AI coding agent just lies to the user that it has none.

The AI agent will be the one to introduce new issues in the codebase regardless of "tests". The new issue is now the non-technical human vibe-coding is none the wiser.

We have already seen this in Codex itself. Imagine this propagated in many other code-bases.

What's the actual issue? Are you being frustrated by people laboring under the assumption that DNS records are being sent by carrier pidgeon or something?

DNS censorship will presumably be based on geopolitical boundaries, which in turn are bound by geography. And I wouldn't be entirely suprised if poor network connections - including those potentially geographically bound (poor weather / flooding / tornados severing or degrading links or power) had some (minor, infrequent) impact on the rate stale cache entries are evicted in favor of fresh ones.

Granted, none of that means a DNS resolver halfway across the globe from the authoritative servers can't typically get updated results to me beyond farming that hacker vibe aura.

But I imagine there's at least one or two dudes out there that'll see a red dot in, say, Australia - and that'll save them a few minutes, by giving them a shortcut to determining the root cause of some issue reported in Australia by letting them correctly guess/blame stale DNS records.

a) different DNS systems get the change out to all the authoritatives different ways. Some of them with much delay. Delays are hopefully minimal on modern systems, but I've worked with bad systems where you change dns in the api and it takes minutes and sometimes hours for the authoritatives to start returning new results; traditional notify/axfr based systems often have a queue of several seconds at least. b) as res…

Percolate?

Nothing wrong with vibecoding a toy project.
