Linux Memory "Manglement" using Raku
by Steven Lembark

Steven Lembark will tell us how memory in Linux is “mangled”..... er, ah “managed” by looking at various system calls and data structures.

We are going to get into the deep weeds. Lets look at the data structures in a running process!

There are process performance & memory data structures that have been defined in the original AT&T UNIX, Posix, & now Linux. While commands like “top” will show you info on many of the process running on your computer, its possible to look within the process itself to get details that can be used “real time”.

He’ll use Raku language which is the follow-on language to Perl but it is similar to C. We’ll be able to follow even if you don’t know Perl or Raku. (Perl was originally intended to be THE LONG AWAITED PERL 6 but was so different they gave it the new name Raku.)

ONLINE MTNGS ONLY until further notice. ONLINE mtngs will use remote video sftwr.
