$ cat bork.asm

section .data
fuck: dd 0xDEADBEEF

section .text
global _start
_start:
mov dword [fuck],0xABADC0DA

mov eax,1
mov ebx,0
int 0x80


Why doesn't writing to the .data segment segfault? Shouldn't Linux map it to a read-only page?

$ nasm -f elf bork.asm
$ gold -s -o bork-gold bork.asm
$ ld -s -melf_i386 -o bork-ld bork.o
$ du -bh *
432 bork-gold
132 bork.asm
340 bork-ld
608 bork.o


How does such a minimal binary take up 300+ bytes?

Machine learning is a victim to the curse of dimensionality
http://en.wikipedia.org/wiki/Curse_of_dimensionality

A game, like Diablo 3, has a lot of instances of some CObject class, which has a some (many) of dimensions on it's own (like monster's health and damage, which itself correlates with weapon's damage and monster's strength). Software pirates can't just simply record statistics from the server and curve-fit observations into the alternative server implementation. Moreover, pirates are usually college dropouts, while analyzing statistics requires a lot of math skills.
