Thanks to Hrvoje for reminding me that I need to publish a new update on my game engine <a href="https://github.com/jan-kelemen/niku">jan-kelemen/niku</a>.</p> <div style="position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden;"> <iframe allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share; fullscreen" loading="eager" referrerpolicy="strict-origin-when-cross-origin" src="https://www.youtube.com/embed/6sTx6-KbQ7Y?autoplay=0&amp;controls=1&amp;end=0&amp;loop=0&amp;mute=0&amp;start=0" style="position: absolute; top: 0; left: 0; width: 100%; height: 100%; border:0;" title="YouTube video"></iframe> </div> <p>Video quality has been massacred by YouTube&rsquo;s compression algorithm.</p> <h1 id="winter-is-coming">Winter is coming</h1> <p>Heating bills are expensive, but thankfully, I have a 220W space heater in my PC. I&rsquo;ve decided it&rsquo;s time to add ray tracing support to the rendering engine. For this purpose, I&rsquo;ve created a new demo <code>heatx</code>. I&rsquo;ll admit, I&rsquo;ve spent way too much time playing Factorio in the meantime. The demo name is a reference to <a href="https://wiki.factorio.com/Heat_exchanger">Heat exchanger</a>.</p>
