The population of Russia is ~146.7M [0]

The population of China is ~1,403M (~1.4B) [1]

This makes China ~9.6 times larger than Russia.

The US is ~327M [2], which makes China about ~4.3 times as large.

It's a big difference, but not as large as 77x.

Terms:

ICANN: The organization responsible for coordinating the maintenance of the domain name system (among other things).

Registrar: A company authorized to update ICANN database on behalf of registrants. Google, GoDadddy, Enom, etc are registrars

Registrants: An entity that wants to register a domain name. In this case, Zoho is a registrant, but it could also be an individual. This is your role if you 'own' a domain.

Authoritative Name Server: A domain name server that is considered authoritative for a specific domain.

Stuff registrars can do (among other things):

1.) They can update the ICANN database to disable a domain completely[1]

2.) They can replace your authoritative name servers with their own or someone else's (ex: botnet domains being reassigned to a security company for dismantling via court order)[2]

3.) If the authoritative name servers for a domain are owned by the registrar, then the registrar can merely change the DNS entries themselves to point to something other than the domain owner's wishes.

"GetItem provides an eventually consistent read by default."

This seems to meet the definition of "DynamoDB's default settings"

It's not an assumption. It's directly in the documentation.

"If the same seed is used for separate Random objects, they will generate the same series of random numbers."[0]

Hydrogen storage is "Approx. 5.0 kg"

122.4L of volume (60L front, 62.4L rear)

pressure is between 70 MPa and 87.5MPa

Doing the math shows:

density of hydrogen at 70MPa equals 36.69 g/L [1]

122.4L at 36.69 g/L equals 4.49kg [2]

density of hydrogen at 87.5MPa equals 45.96 g/L [3]

122.4L at 45.96 g/L equals equals 5.63kg [4]

So the amount is somewhere between 4.5kg and 5.63kg, depending upon the final pressure after filling. Which seems to line up squarely with "Approx. 5.0kg".

Here is the source for information on the attack that only requires a single EAPOL frame[0].

"This attack was discovered accidentally while looking for new ways to attack the new WPA3 security standard. WPA3 will be much harder to attack because of its modern key establishment protocol called "Simultaneous Authentication of Equals" (SAE).

The main difference from existing attacks is that in this attack, capture of a full EAPOL 4-way handshake is not required. The new attack is performed on the RSN IE (Robust Security Network Information Element) of a single EAPOL frame.

At this time, we do not know for which vendors or for how many routers this technique will work, but we think it will work against all 802.11i/p/q/r networks with roaming functions enabled (most modern routers).

The main advantages of this attack are as follow: No more regular users required - because the attacker directly communicates with the AP (aka "client-less" attack) No more waiting for a complete 4-way handshake between the regular user and the AP No more eventual retransmissions of EAPOL frames (which can lead to uncrackable results) No more eventual invalid passwords sent by the regular user No more lost EAPOL frames when the regular user or the AP is too far away from the attacker No more fixing of nonce and replaycounter values required (resulting in slightly higher speeds)" [0]
