As a moderator of a decent-sized subreddit, the number of people who complain they weren't aware of our rules because they use a mobile client (that makes it impossible to view the sidebar, where the rules are mentioned) suggests to me there's a ton of mobile users you're discounting.

Daring Fireball has experimented with this over the years.

Currently it uses a sponsor system.

You don't need root, and you don't need physical access. For Meltdown, you only need the ability to run your own code on the target machine.

Where that gets tricky is when everyone's using cloud hosting solutions where the physical machines are abstracted away, and a given physical server may be running multiple virtual servers for different customers.

Think of it like this:

* Somewhere in a data center at a cloud provider is a physical server, wired up in a rack..

* That server runs virtualization software, allowing it to host Virtual Server 1, Virtual Server 2, and Virtual Server 3.

* Virtual Server 1 belongs to Customer A. Virtual Servers 2 and 3 belong to Customer B.

* Normally, Virtual Server 1 can't access any memory allocated to Virtual Servers 2 and 3.

* BUT: Customer A can now use Meltdown to read the entire memory of the physical server. Which includes all the memory space of Virtual Servers 2 and 3, exposing Customer B's data to Customer A.

That's the threat here.

There's some historical baggage here.

Consider a man being helped along the street by his friends. He's stumbling, often falling over, unable to keep going in a straight line. A police officer walks up and asks them what's wrong.

Scenario 1: his friends say "He's drunk off his ass."

Scenario 2: his friends say "He has imbibed intoxicating beverages to excess."

To many native English speakers, if you presented those two as skits, they'd find the second one much funnier. And the reason would be the use of "high-class" vocabulary in a decidedly low-class situation (a drunk stumbling along the street).

Now consider the English word hydrogen. And then consider the German word Wasserstoff. Native English speakers sometimes find the German word funny -- it sounds just like "water stuff"! But they don't reflect on the fact that "hydrogen" means essentially the same thing when you look at the Greek roots.

This happens because words with Germanic roots are often "low-class" in modern English, while words with obvious Greek and Latin roots are high-class. And that... is because modern English developed after the (Romance-language-speaking) Normans took over England from the (Germanic-language-speaking) Anglo-Saxons. The vocabulary of the Normans, since they were the ruling class, is prestigious in modern English, while the vocabulary of their Anglo-Saxon subjects isn't.

And guess what language family Icelandic is in?

Wait.

You mean the Pope -- the leader of the Roman Catholic church -- believes in the Catholic interpretation of the doctrines of grace and of original sin, and bases his world view on them?

I am shocked, literally SHOCKED, to learn this, anonymous internet person who is playing at not understanding the source of the quote in order to launch nit-picky off-topic jabs about religion.
