The world continues to embraces Rust for its safety properties. While writing utilities in Rust, we are going to have to work with existing code to perform common tasks. I recently needed to list the set of Linux groups registered on a system, and get access to the users assigned to each. Here’s my notes of what I learned.
Continue readingI’m writing a simple utility for manage the /etc/hosts file. I want it in a native language so I can make it SUID, or even better, to lock it down via capabilities. I want to remember how to code in rust. Once I get a simple bit working, I want to refactor. Here’s what I did.

Continue readingPython is a great language, but sometimes I miss type safety. While I was always comfortable with C++, I know that the lanugague has it’s warts. Lately, I’ve been taking an interest in Rust, which seems to be set to address many of the shortcomiings of C++. What better way to learn it than to try and use on problems I already know well; OpenStack and Keystone? So, I wrote my first non-trivial program, which gets a Keystone token.
