Welcome to rozmichelle.com!
On this site, you will find all kinds of creative outlets, with topics including poetry, travel, design, and development. I like to think of my site as a diverse representation of me as I strive to master self-understanding. I started this website in 2005 and it continues to be a source of expression for me as I design, write, cook, and code my way through life. I hope you enjoy the journey!
Thank you so much for being here, and please sign my guestbook or send me a message if you are inspired by this site in any way.
Writing an operating system is no easy feat, but it is extremely rewarding and helps polish the skills of even the most accomplished programmer. Operating systems are beautiful and complex, and understanding them is merely the first step to implementing them. In this class, we learned how to write an operating from scratch on the popular handheld computer Raspberry Pi. Previous courses at Stanford like CS107 and CS110 teach topics like processes, memory, and file systems, but this class delves deeper by teaching you how to implement these features from the ground up. In addition, this class does this using the Rust programming language. A major goal of this class is to understand the inner workings of an operating system: to not only know which gears it contains but to also understand how to turn those gears. Let’s take a closer look at the mechanics of the operating system we built in this class. Continue reading →
I'm currently enrolled in a systems programming class at Stanford (CS110: Principles of Computer Systems). It is the second systems class I've taken (the first was CS107 which teaches C and focuses on understanding pointers and memory management). This class focuses mainly on the inner workings of the operating system, using C and C++ to teach us concepts like process management, program execution, and handling data. While I enjoyed and quickly grasped the concepts taught in CS107, I've had a harder time understanding the material in CS110. The class itself is extremely interesting and well-taught, but my main pain point has been understanding the way processes share data and how input and output work across commands entered in the terminal. In the last few days, however, I finally found clarity when I started creating diagrams to model process behavior and the path that data takes as it travels from one command to another. I'd like to share what I've learned with you. In this post, we'll go over how Unix commands pass data to each other via pipes and input/output redirection and I'll illustrate what actually happens to the flow of data when a command is executed.

I see you through rose-colored glasses
But you wear dark shades
You’re hiding from my sunlight
While I bathe in your rain
My love is never-ending
But I have such limited time
With me, there’s no storm coming
Only blue skies and infinite shine Continue reading →
