Our entire world runs on computers, but few understand how they work at the lowest level. Everything, from your phone and laptop to the flight controllers on an airliner, has at least one computer chip in it called the CPU, which tells it what to do.
In this video, we make massive improvements to stdlib, add memset and memcpy, and most importantly, allow ourselves to get out of VGA (graphics) mode once we enter it.

So long, old friend
In this video, we set up unit testing for our C code using Gtest, generate coverage data with gcov and LCOV, and finally generate a nice HTML coverage report for us to browse with genhtml.
In this video, we implement a simple integration test in GitLab CI/CD to automate our input to QEMU using pytest and Python's subprocess package.
Our OS just got a lot more colorful. In this post, we figure out how to draw on the screen by switching to VGA mode and manually editing the video memory.
In this video, we reorganize the entire project, taking it from cluttered to modular in less than 10 minutes.
This video shows off our shiny new Docker development environment, and this new PageKey Solutions website!
In this video, we learn about interrupts and write our own basic keyboard driver!
