            I started writing two operating systems from scratch.
        </p>
        <p>
            <a href="https://lukas-eisenhauer.de/git/lukas/tree-os">Tree OS</a> was the first iteration which is able even read files from an attached SATA disk. However, the design unintentionally turned into a huge monolithic kernel.
        </p>
        <p>
            <a href="https://lukas-eisenhauer.de/git/lukas/honey-os">Honey OS</a> is the new one where I actually went trough the effort to correctly implement multiple program environments. Therefore, multiasking is made possible and there are a number of different system
            calls implemented. Furthermore, each process has its own memory space as in any other modern operating system to avoid interference between processes.
        </p>
        <p>
            Even though the project will probably never have any real use, learning about the x86 architecture was really beneficial.

            For school, I have to write a scientific article about a topic related to "everyday physics". I am focusing on the design of urban junctions and need a simulation for cars traversing different designs. You can find the current code

        <h2>Websites</h2>
        <p>
            I personally created this website you are currently looking at using
            <a href="https://angular.io">Angular</a> and the
            <a href="https://material.io/design">Material design theme</a>. Additionally, I also created
            <a href="https://www.mpe.mpg.de/~eisenhau/">Frank Eisenhauer's webpage</a> and host an instance of
            <a href="https://lukas-eisenhauer.de/git">gitBucket</a>.
        </p>
        <p>
            The backend was made using <a href="https://rubyonrails.org/">Ruby on rails</a> and is responsible for the quotes you can see at the bottom of the page.

            For the open source Minecraft client <a href="https://gitlab.bixilon.de/bixilon/minosoft">
                Minosoft</a>, I developed the voxel-rendering engine and implemented major parts of the physics as well. Additionally, I started development on a new GUI rendering system which wasn't merged.
