Surely Windows keeps the FVEK in RAM regardless of whether the TPM requires a PIN to initially obtain it. Otherwise, wouldn't you need to enter your PIN every time a block from the disk needs decrypting? Not to mention the performance impact of calling the TPM on every disk operation.

This attack reads the key from RAM, so I don't see how a TPM PIN would mitigate it.

derekerdmann · 8 months ago

Correct, unless you're using a self-encrypting drive the FVEK sits in RAM once it's been released by the TPM during boot. The TPM is only a root of trust; for fast crypto operations without keeping the key in kernel memory you would need something like Intel SGX or ARM TrustZone.

Somewhat unrelated: I’m looking for a comprehensive overview of why the CAGED system works on guitar. I see lots of mechanical explanations of how to use it to play various chords down the neck, but nothing explaining the theory behind it.

Take a look at Fretboard Theory by Desi Serna - it spends a lot of time on how different scales are constructed and relating different patterns and chord forms back to the underlying concepts.

Decades ago I read about NASA's silent room, with the big wood spikes on the walls. All you can hear is your heartbeat and this high pitched whine. NASA figured out the high pitched whine was the nervous system (like, your brain).

I've got some mild tinnitus. I always wonder if it's my brain listening to itself. That little recursive loop is enough to distract me, even if it's not true.

Yeah, no. They're different things. Formal methods, including static analyzers, can prove the absence of issues in all possible conditions under some assumptions. Tests verify that implementation, under the tested conditions, once.

You can't replace testing with formal methods, but formal methods are more powerful when they work. That sqlite hasn't found them useful is just a reflection of how absurdly far out they are on the testing spectrum and how complicated the problem domain they're operating in is (very).

derekerdmann · 2 years ago

Static analyzers are NOT formal methods. Reporting no issues just means your tool didn’t find anything, not that your program is correct.

can somebody with more server/home server experience explain to me the benefit of going with a rackmount setup vs let's say, just building a second PC to use as a home server? I recently bought a house and am excited to get into home networking/home server work, but don't know anything about rack mount. Is rackmount equipment cheaper than regular consumer PC hardware?

Never

> 1. Packet captures don’t use the correct channel

I've also seen this on a 2020 Intel MacBook Air. I assumed it was a Big Sur issue but had never tried it on Catalina.

Sniffing from the command line did pick up the correct channel: https://unix.stackexchange.com/a/49317/36875

Upstate NY is not Yankeedom. It is Greater Appalachia.

Also, many of the Midwest states are less Yankeedom and more Heartland.

Also, Dallas is Greater Appalachia and not Deep South yet Houston is Deep South and not New France?

Also, LA is El Norte and not the Left Coast?

Was this map based on 200 year old data?

derekerdmann · 6 years ago

Greater Appalachia definitely extends through PA in a T shape across the center of the state and the northern border (sometimes called Pennsyltucky) and covers at least the Southern Tier in New York.
