I overlaid some of @trvrb group's analysis of effective Reproductive Number over time since a variant first starts spreading.
XBB.1.5 appears faster and more sustained than ANY of the variants since Omicron's first wave last January.
Current Rt 1.6-1.8

A lot of the recent policy debates around surveillance/encryption start from the frame of police *losing capability* but nobody ever talks about how quickly their capabilities have grown. Did we have a democratic debate about ubiquitous location surveillance?

It's easy for people to issue security warnings _after_ systems are broken. What takes much more work is _proactively_ analyzing risks deeply enough to issue meaningful warnings _before_ systems are broken. Here's a 2021 example, disputing the "case for SIKE" security analysis.
Agreeing with main points in 3, 4, 6, 10 in eprint.iacr.org/2021/543. More objections to 2, 5, 7, 9. Most important dispute is regarding risk management, 1+8. Recent advances in torsion-point attacks have killed a huge part of the SIKE parameter space, far worse than MOV vs ECDLP.

We found a way to leak data on Apple Silicon processors that is "at rest": that is, data the core never reads speculatively or non-speculatively.
This will be an odd one, so stick around for the 🧵 and see prefetchers.info

COWORKER: we need to find the root cause asap
ME: *takes long drag* the root cause is that our processes are not robust enough to prevent a person from making this mistake
COWORKER: amy please not right now
