<p>This blog series creates a small operating system in the <a href="https://www.rust-lang.org/">Rust programming language</a>.
We start from scratch and build it in small steps. Each post is a
tutorial and includes all needed code, so you can follow along if you
like. The source code is also available in the corresponding <a href="https://github.com/phil-opp/blog_os">Github
repository</a>.</p>
<p>First, we create a minimal 64-bit kernel and do the initial Rust setup.
Then we explore virtual and physical <a href="#memory-management">memory management</a>.
The latest post is: {% for post in site.posts limit:1 %}
  <strong><a href="#{{ post.id }}" onclick="
    post = document.getElementById('{{ post.id }}');
    post.className = post.className.replace(/\b updated\b/, '');
    post.offsetWidth = post.offsetWidth; // trigger reflow -> works on 2nd click, too
    post.className += ' updated';
  ">{{post.title}}</a></strong>
{% endfor %}</p>
