TECH WORKERS: There’s a petition calling on our leaders to get ICE out of our cities, and to cancel all contracts with the agency. Sign and share the petition at https://iceout.tech/, and then look for ways to get organized at work.

@rk My dog has gotten accustomed to having his paws wiped and handles it pretty cooperatively. He'll calmly let me lift and wipe off each one in sequence as he stands there, but for some reason always seems to think we're done after three; the fourth is somehow a surprise to him each time.

@cks Seems a bit of an odd exercise -- using FDE in the first place would seem to imply a threat model that includes a local attacker with physical access to your hardware; given that, wouldn't it be fairly simple for such an adversary to extract the (unencrypted) SSH host key from the initramfs and use it to steal the LUKS passphrase via MitM?

Glancing through @paulmckrcu's perfbook, it occurs to me that the strength/weakness of a CPU architecture's memory model is in most cases reasonably approximated lexically.

How does SPARC compare to Itanium? Well, I comes before S, so ia64 is the weaker of the two.

@rk @cks @mothcompute I believe AFS has a similar mechanism wherein a symlink named @foo resolves to the output of runing foo as a command -- primarily used in the form of @sys, which would point to e.g. linux-i386 or sunos-sparc or whatnot for bin directories and such in the days of more heterogeneous networks.

(Granted, I wonder if it was really just that support for that particular pattern was special-cased, given what a nightmare it would be implementation-wise and performance-wise to actually execute arbitrary commands in the middle of namei() or the like...)

This MacOS (APFS?) quirk was mentioned at the pub last night, and I still cannot believe this actually works when I tried it myself
