I am excited to offer evening and weekend Computer Science tutoring at Harvard University, MIT, Northeastern University, Boston College, and Boston University. I offer in-person sessions one or two days per week at each university, and remote sessions are available 7 days a week to all university students enrolled in Computer Science classes.

About Me

Hi! My name is Ryan Torok, and I work for zeroRISC, a startup company in Boston developing a cloud security service for the OpenTitan project. I hold a Master's degree in Computer Science from Princeton University and a Bachelor's degree in Computer Science from the University of Texas. I am interested in all things related to computer security and systems. In 2023, I gave this talk at IEEE Security Conference about my research paper I authored with Amit Levy at Princeton about a novel defense against privacy attacks in web browsers. When I'm not working on CS-related business, I enjoy playing the cello, composing music, running, and hiking.

You can learn more about me at my homepage.

What do I teach?

My specialty is in Computer Security and Computer Systems, including Operating Systems, Distributed Systems, and Networking. However, I have ample proficiency to teach in nearly all areas of Computer Science, including:

Introductory Programming Data Structures and Algorithms
Discrete Mathematics Differential and Integral Calculus
Matrices and Linear Algebra Probability and Statistics
Systems Programming in Unix Computer Architecture
Databases and Storage Technologies Operating Systems
Theoretical Algorithms Computer and Wireless Networking
Distributed Systems Computer and Network Security
Introductory Machine Learning Blockchains and Decentralization

What is my teaching philosophy?

Coding is intimidating. College is intimidating. Life is intimidating. Asking for help shouldn't be.

As a self-proclaimed veteran of five TA roles at Princeton University and the University of Texas, I have always found my students have learned best when they felt the freedom to ask questions, get stuck, ask me to discuss their ideas about how to get un-stuck, and then use the process through which we come up with a solution as a learning tool to solve future problems.

I seldom view finishing an assignment or passing an exam as an end goal for my students. When I walk a student through the solution to a problem, I use the problem as a tool demonstrate the why behind the solution. Why does a particular algorithm work? Why does a block of code behave the way it does? Why did a particular issue with a piece of code break the solution? By discussing these types of questions during one-on-one sessions, I observe that students are much less likely to repeat mistakes, and much more likely to be able to reproduce the solutions to problems, apply them to other problems, and explain them to other students in simple words.

Rates

Individuals: $35 per 60 minute session

About this website

I wrote this website entirely myself, using HTML, CSS, and JavaScript for the frontend browser application, and Rust for the backend server, using the Rocket and Diesel libraries and PostgreSQL for the database.

Yes, I could have used an existing online scheduling app like Calendly or Doodle, but I had several reasons for not doing so. First, these services use a freemium model that offers limited functionality in the base version and requires upgrading to a commercial licence to use the full version. By writing the server myself, I can ensure that I implement all the functionality I need, and if I ever outgrow it, I can upgrade whenever and however I want.

A second reason is to set a good example when it comes to privacy. An alarming number of websites include invisible HTML tags served by Google, Meta, and other companies that allow them to track the pages you visit. You can verify this yourself by installing the NoScript extension in Firefox (which I highly recommend, by the way). You'll find nothing of the sort running on my website. Web tracking aside, I decided early on that using a spreadsheet on Office 365 or Google Sheets was not a viable method for scheduling, because your name and contact information would be visible to the public internet. When and whether you schedule tutoring sessions should be no one's business but yours and mine, and my server implementation allows me to uphold confidentiality.

The third, and perhaps most important reason, was to learn. Though I have been proficient in Rust for several years, I had not used either Rocket or Diesel before creating this website, and I decided the best way to familiarize myself with both libraries was to write a server with them. Often, the best way to learn a programming language, framework, or library is to use it.
