问题 I'm relatively new to x64 assembly and im using it in conjunction with VS2010. I'm struggling to get a handle on the return values from a proc and I can't really find quality documentation for beginners. .data MyByte db 10 .code GetValueFromASM proc mov rax, 28 mov rbx , 19 lea rax, MyByte mov rax, 10 mov eax, 11 mov ecx, 100 ret GetValueFromASM endp end The Ret instruction is printing out the value of eax in my c++ front end, is there some sort of default return register or can you specify

Should using MOV instruction to set SS to 0x0000 cause fault #GP(0) in 64-bit mode?

问题 This question is inspired by a Reddit question in r/osdev except that this question focuses on the SS register. One may say RTFM (ISA entry for MOV), but when this question comes up it can get varying answers even among OS developers. Question : Should using the MOV instruction to set SS to 0x0000 cause a general protection fault #GP(0) in 64-bit mode? For example: If I am in 64-bit mode with a Current Privilege level (CPL) of 0, should I expect to see a #GP(0) with this code snippet: NULL

问题 What is MongoDB's storage size limit on 64bit platforms? Can MongoDB store 500-900 Gb of data within one instance (node)? What was the largest amount of data you've stored in MongoDB, and what was your experience? 回答1: The "production deployments" page on MongoDB's site may be of interest to you. Lots of presentations listed with infrastructure information. For example: http://blog.wordnik.com/12-months-with-mongodb says they're storing 3 TB per node. 回答2: The MongoDB's storage limit on
