Executables deciphered

What's inside a compiled Hello, World program? Julia Evans is on that. How to read an executable:

Executable file formats are regular file formats that you can understand. I’ll explain some simple tools to start! We’ll working on Linux, with ELF binaries. (binaries are kind of the definition of platform-specific, so this is all platform-specific.)

I thought I had a rough grasp of how executables worked, and I still learned things. I love this format too. Julia Evans writes these fearless, curious posts about the deeply mysterious underpinnings of our computers and I learn a lot every time. More like this, please!
