What’s in the Golang syscall package? No, wait. . .back up a bit. What’s a syscall? And what do people mean when they talk about the kernel or glibc?
Syscalls provide the interface between your code and the operating system. Liz Rice started playing with Linux syscalls to understand more about how containers work, which made her wonder what’s happening under the hood when you make a system call and what else you can do with them. Liz offers an overview of syscalls, exploring the different layers of how everything fits together and what happens when you make a higher-level call in your code. Along the way, Liz does some live-coding to demonstrate some interesting features.
Join in to gain insight into what’s going on at a system level when you run your code. As a developer, you probably don’t need to know these details day to day, but it’s always good to know how things work.
Liz Rice is the technology evangelist at container security specialists Aqua Security. She has a wealth of software development, team, and product management experience from her years spent working on network protocols and distributed systems and in digital technology sectors such as VOD, music, and VoIP. When not building startups and writing code, Liz loves riding bikes in places with better weather than her native London or racing in virtual reality on Zwift.
