> Felix Ulmanu is our [Washington D.C.](/meetups/dc) meetup host. You may reach the author at felix@handmadecities.com

<p>Join us this Saturday, 24 January 2026, from 1:45pm to 2:45pm, to discuss API design and single-header libraries. How should we structure and program libraries to impose as few usage constraints as possible? We&rsquo;ll look at <a href="https://github.com/nothings/stb">the STB libraries</a> and other examples as case studies.</p>  <p><strong>Please note the slightly different time than usual</strong> (though after 2:45pm, we may continue chatting over lunch nearby). We&rsquo;re still at the <strong>West End Library</strong>, 2301 L St NW, Washington, DC 20037, in <strong>Meeting Room 2</strong>. See you soon!</p>  <h2>Contact</h2>  <ul> <li><code>_felixu_</code> on Discord, or reply to this email</li> </ul>  <p>Note that it appears Gmail may send this announcement to &ldquo;Promotions&rdquo;.
