Brutal.

When Microsoft acquired GitHub.

@futurebird there are multiple YouTubers who specialize in Stardew valley challenge runs, I believe some of them have managed to do this.
Quantum computers need vastly fewer resources than thought to break vital encryption

No, the sky isn't falling, but Q Day is coming, and it won't be as expensive as thought.

@emc2 @targetdrone yeah. In fact I'm worried that in some sense slower and less accessible CRQC paradoxically pose a greater risk to the common people: if, at the extreme but imaginable end, it takes two months to break a key, and you only have one quantum computer, exploiting SNDL for random cables very quickly becomes unsatisfying. And breaking fairly few supply chain keys (CA, CT logs, identity providers, software signing etc) becomes very tempting, even if it risks giving away that you have a CRQC at your disposal. And those supply chain risks in turn put everyone at risk, not just some limited spy games between embassies.

Signal chat out of context.

@paulehoffman

@targetdrone @emc2 yeah, CAs and CT logs are the keys you want.
@sophieschmieg When people question the aggressive quantum readiness timelines given that 100 qubit computers are all we have today, I have to explain that it's not just a matter of building a computer with a million qubits, but that researchers are still publishing optimizations that may cut that by a factor of 10, or 100, or more. And we simply don't know if or when they'll figure out something better.
@soatok @tiefling @hazelnoot @defcon I hazard the guess that Las Vegas, of all places, has a very healthy supply of HIV testing, condoms, and similar.
@tomgag these are not the only quantum physicists that have said that recently.
@ar1 the timeline got moved in substantially. Of course things can go wrong for the physicists, but 3 years seems feasible now.
