What is the reference to Plan9 here?

!x has been a shell history expansion since at least csh (1978?).

OVH operates three hosting brands:

OVH, SYS (So You Start), and KimSufi. It's a bit confusing!

IIRC they bring the newest hardware into OVH and push it down the line to SYS and KS as it ages.

That's funny as a human, amazing as a developer, and terrifying as a data processor. All at the same time.

I'll bet that pair has stories to tell.

Voting errors and fraud are reversible. Instances of errors are reversed in every election. Instances of fraud are very very rare, but also reversed.

This happens before the winners are certified, and before they're given the ability to drop bombs.

I don't understand your confusion.

In the US, ACH transactions are reversible and trusted throughout the nation. Bitcoin transactions are not, and are not. This seems parallel to me.

If you were the government, and the legal structure gave you an obligation to do X, you would do X.

Your implied comparison of "promotion" vs "monitoring" makes zero sense though.
