Arenas in Rust
There’s been some discussion about arenas in Rust recently, and I thought I’d write about them. Arenas aren’t something you would typically reach for in Rust so fewer people know about them; you only ...

FHE is really cool, Laurie's thread has great pointers, check it out!
However, FHE isn't the only answer to "encryption-in-use". Other solutions exist that are efficient, employ well-established cryptography, and are deployable today!
Naturally, there's a catch:

Naturally, there's a catch:
Encryption is kind of a lie.
Data can be encrypted at rest, and even in transit…but not “in use”.
Fundamentally, CPUs execute arithmetic instructions on decrypted plaintext; even with secure enclaves.
But what if we got *really* clever:

Rewatched Jaws. Spielberg is so effortless with his storytelling it's stupid. The car ferry oner is a masterclass of blocking,* and it's not even close to top 5 shots in this movie.

There is a lot of demand for digital privacy and security advice out there right now and lots of people are giving advice and writing guides. I beg them to do a few things:
1. Be explicit about the threat model your advice is meant for.
