 I enjoy making educational YouTube videos such as _The Just One More Paradox_ (see below).
 I made this video before I had any formal education in probability, so the explanations aren't very rigorous, but all the concepts still hold.

 - **Machine Learning** - Here I used PyTorch and Numpy to implement algorithms such as LASSO regression, stochastic gradient descent, and backpropagation.
 
+- **Operating Systems** - In this course I took an experimental kernel which runs directly in QEMU, and implemented system calls like `fork()`, `wait()`, `sbrk()`, `open()`, `write()`, and more. I implemented filesystem journaling, page table management, and page fault handling.
+
+- **Computer Security** - Computers are everywhere: cars, pacemakers, phones, airplanes, printers, etc. How can we prevent an attacker from shutting them down or extracting secrets? That was my guiding question as I learned about buffer overflows, cross-site scripting, SQL injections, double-free errors, and more.
+
+- **Introduction to Computer Communication Networks** - In this course I took a deep dive learning about network protocols including IEEE 802.11, ethernet, ARP, DHCP, IP, DNS, UDP, TCP, HTTP, and HTTPS.
+
 - **Introduction to Digital Design** - Here I wrote a snake game in SystemVerilog. SystemVerilog is a language that compiles into logic gates and can be run on FPGAs (field programmable gate arrays).
