Howdy Hackers.

Lets have a heart-to-heart.

I love Noisebridge.

I really do love Noisebridge.

To say that my motivations for moving 3,000 miles from Akron, Ohio to put down roots on the west coast did not include Noisebridge would be a lie.

Codius Sandbox Eventing

At some point, a sandboxed process will try to run a syscall that interacts with IO, such as:

open(const char* path, int mode)

Within our sandbox, the following events happen:

1. The process calls libc's open call
2. Libc translates this to system(SYS_open, path, mode) using the constants in /usr/include/asm/unistd_64.h
