  • I think -k 1048576 means $1048576 \times 1024 = 1073741824$ bytes.
  • I think BlaMka (modified Blake2b) has a block size of $512$ bytes in Argon2.
  • I think -t 20 means repeat the work on the entire $1073741824$ bytes memory pad for $20$ times.

So, I think, the total number of times BlaMka is called is:

$$ 20\frac{1073741824}{512} = 41,943,040 $$

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
