        <h2>OS development</h2>
        <img src="https://lukas-eisenhauer.de/git/lukas/honey-os/blob/master/honey-os.png?raw=true">
        <p>
            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
            to read files from an attached SATA disk. However, the design unintentionally turned into a huge
            monolithic kernel, making further expansion very difficult.
        </p>
        <p>
            <a href="https://lukas-eisenhauer.de/git/lukas/honey-os">Honey OS</a> is the new one where I actually
            went through the effort to correctly implement paging. Therefore, multiasking is made possible and there are
            a number of different system calls implemented. Furthermore, each process has its own memory space to avoid
            interference between processes.
        </p>
        <p>
            Even though the project will probably never see any real world use, learning about the x86 architecture is
            really beneficial.

        <p>
            For school, I wrote a scientific article about a topic related to "everyday physics". I focused on the
            design of urban intersections.
            For this, I needed a simulation for cars traversing different designs. You can find the souce code
            <a href="https://lukas-eisenhauer.de/git/lukas/Traffic-Simulator">here</a>.

            I developed an Android application to dynamically synthesize music. Behind the android and kotlin frontend,
            some c++ code for the sound synthesis is running in the background.

        <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.

        <h2>Schrodinger equation</h2>
        <img src="assets/schrodinger.png">
        <p> I created a presentation discussing the Schrodinger equation for school. You can have a look at it <a
                href="https://lukas-eisenhauer.de/schrodinger/presentation_main_German.html">here</a>. It is created
            using the reveal.js presentation framework. The source code including a custom multilingual markdown parser
            can be found <a href="https://lukas-eisenhauer.de/git/lukas/schrodinger">on my gitbucket</a>.

            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.
