I am interested in testing macroevolutionary hypotheses, developing methods and writing software. This includes, amongst others, phylogenetic models of species diversification (birth death models), models of continuous  trait adaptation, and models of discrete character evolution. My favorite groups are  even-toed ungulates and bryozoans!</subtitle><entry><title type="html">Welcome to Jekyll!</title><link href="/jekyll/update/2026/04/24/welcome-to-jekyll.html" rel="alternate" type="text/html" title="Welcome to Jekyll!" /><published>2026-04-24T09:21:17+00:00</published><updated>2026-04-24T09:21:17+00:00</updated><id>/jekyll/update/2026/04/24/welcome-to-jekyll</id><content type="html" xml:base="/jekyll/update/2026/04/24/welcome-to-jekyll.html"><![CDATA[<p>You’ll find this post in your <code class="language-plaintext highlighter-rouge">_posts</code> directory. Go ahead and edit it and re-build the site to see your changes. You can rebuild the site in many different ways, but the most common way is to run <code class="language-plaintext highlighter-rouge">jekyll serve</code>, which launches a web server and auto-regenerates your site when a file is updated.</p>

<p>Jekyll requires blog post files to be named according to the following format:</p>

<p><code class="language-plaintext highlighter-rouge">YEAR-MONTH-DAY-title.MARKUP</code></p>

<p>Where <code class="language-plaintext highlighter-rouge">YEAR</code> is a four-digit number, <code class="language-plaintext highlighter-rouge">MONTH</code> and <code class="language-plaintext highlighter-rouge">DAY</code> are both two-digit numbers, and <code class="language-plaintext highlighter-rouge">MARKUP</code> is the file extension representing the format used in the file. After that, include the necessary front matter. Take a look at the source for this post to get an idea about how it works.</p>

<p>Jekyll also offers powerful support for code snippets:</p>

<figure class="highlight"><pre><code class="language-ruby" data-lang="ruby"><span class="k">def</span> <span class="nf">print_hi</span><span class="p">(</span><span class="nb">name</span><span class="p">)</span>
  <span class="nb">puts</span> <span class="s2">"Hi, </span><span class="si">#{</span><span class="nb">name</span><span class="si">}</span><span class="s2">"</span>
<span class="k">end</span>
<span class="n">print_hi</span><span class="p">(</span><span class="s1">'Tom'</span><span class="p">)</span>
<span class="c1">#=&gt; prints 'Hi, Tom' to STDOUT.</span></code></pre></figure>
