Seeding PRNGs with sufficiently unpredictable data was a real security concern for a while. New cloud instances have a small entropy pool space for attackers to enumerate due to lack of a real source of randomness. (See the Debian/OpenSSL issue for what can happen when your entropy pool is too small/predictable)

One fun fact about XOR is that anything XOR'd with a uniform random distribution results in a uniform random distribution, so there isn't any harm in mixing additional non-attacker-controlled entropy sources in as long as at least one of them is sufficiently unpredictable. The lava lamps provide a potentially hard-to-predict source of entropy for this, but if it's not available then it certainly doesn't "take down the internet". They'll still use packet arrival timing, interrupt timing, etc to seed their CSPRNGs.

Not sure if Double's underlying brokerage is reporting everything necessary for this to be the case though, as I believe some brokerages don't.

It gets 35mpg city and highway, 1mpg less than the front wheel drive Sienna (which, to be fair, is also a hybrid)

Things like my printer and wifi-connected grill live on a much more restrictive VLAN. (with some firewall rules to allow devices on the trusted network to still print to my printer's hard-coded IP address)

>While it is true that Nvidia cards are generally preferred by miners due to better price-to-performance, AMD GPUs such as the Radeon RX 6600 XT could still be mined on profitably until recently. […] So yes, carefully consider the condition of all used graphics cards—Nvidia or AMD.

Nvidia has been working hard(er than their competition) on the software side for almost 2 decades to be in the position they find themselves today. 16 years ago, they released CUDA for general-purpose computing on GPUs, and then 9 years ago they followed that up with cuDNN. They have a consistent pattern of making a intentional, long-term bets to diversify their market exposure and unlock new product areas while building a software ecosystem moat.

Yes, they obviously got super lucky with the cryptocurrency frenzy, but there's a reason all the miners were mostly buying Nvidia cards instead of AMD cards.

Also, many postpaid plans (like my home ISP) require SSN because they are providing you service on credit. Postpaid cell paone plans have been the "default" in the US for a long time, though prepaid seems to be gaining market share.

Are you making a rate limiting/ddos argument about "turning them all on at the same time"?

IIRC some of the information about their approach is considered sensitive so I won't elaborate further.
