GopherCon 2017: Liz Rice - A Go Programmer's Guide to Syscalls

Even if you've never used Go's syscall package - in fact even if you've only ever written "Hello, world" - you have definitely used syscalls. They provide the interface between your code and the operating system. In this talk we'll go under the hood to explore what syscalls are, how they work, and how some common Go code makes of use of them. We'll cover what people mean when they talk about libc / glibc, and look at what syscalls have to do with privileges and permissions, with plenty of demos to illustrate what's happening.

Excellent talk. The reason wait4 is so named is very prosaic. It's simply because it takes four arguments, though there is indeed a history (if you go back far enough, there was only wait() which took a single argument, the address of the status).

Amazing presentation! Really inspiring. I learnt a lot!

[@pm71241]

It always gets emotional when you use TeX to demonstrate syscalls ;-)

[@rewanthtammana]

I cannot stand that tsk thing she does

[@chirag.photos]

This is how sages / rishi-munis shared knowledge of Vedas to their students .. She's no less ✌🏽💥

[@edgeeffect]

Of the "new languages" I'm far more interested in Rust than Go.... but Liz is a really really good speaker.... I wish we had someone of this calibre "on our side"....

rax registers are in x64, not x86

[@kalekold]

@@RubberGopher Yes but she mentioned x86 which is 32bit. x86_64 is what she should have used.
