Understanding the ELF

I wrote an ELF binary which, when run, prints itself on standard output. It doesn’t “cheat” by reading its own file. Instead, it uses how ELF binary files are loaded into memory. To explain how the program works, I’ll show you it byte-by-byte. Along the way, we’ll learn about files, programs, the ELF format, and tools for working with these things.

I just released Vidrio, a free app for macOS and Windows to make your screen-sharing awesomely holographic. Vidrio shows your webcam video on your screen, just like a mirror. Then you just share or record your screen with Zoom, QuickTime, or any other app. Vidrio makes your presentations effortlessly engaging, showing your gestures, gazes, and expressions. #1 on Product Hunt. Available for macOS and Windows.
