I picked up an old library copy of the illustrated Scribner's edition Robert Heinlein's Space Cadet and am having fun reading it and pondering the seemingly artless and unresolved juxtaposition of the 1940's-sexist first section of the book with the final section involving the matriarchal Venerian society. But I have a much simpler sci-fi trivia question to ask here.



What is the meaning of the name of the ship that is called P.R.S. Aes Triplex? I checked with my medievalist wife, and she told me "aes" was pronounced like English "ace," then looked up the word and found that it meant "bronze," or some related meaning involving bronze coins or payments. So "triple bronze?" Huh? I'm guessing that "triplex" somehow relates to the three planets with native intelligent life: Venus, Earth, and Mars.

This is a reference to Horace, Ode 1.3:




Illi robur et aes triplex circa pectus erat
qui fragilem truci commisit pelago ratem primus




My Latin is rusty, but basically "the first man to sail fragile ships in the deep ocean wore armor of oak and three layers of bronze around his chest.



The term "aes triplex" becomes from this a metaphor for courage, especially relevant to the Space Patrol.

How many registers does an x86_64 CPU actually have?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this
