Where is the code?

The code for each post lives in a separate git branch. This makes it possible to see the intermediate state after each post.

The code for the latest post is available here.

You can find the branch for each post by following the (source code) link in the post list below. The branches are named post-XX where XX is the post number, for example post-03 for the VGA Text Mode post or post-07 for the Hardware Interrupts post. For build instructions, see the Readme of the respective branch.

You can check out a branch in a subdirectory using git worktree:

git worktree add code post-10

The above command creates a subdirectory named code that contains the code for the 10th post ("Heap Allocation").
