Puffy is of course also the name of the mascot, a <a href="https://en.wikipedia.org/wiki/Tetraodontidae">blowfish</a>, of the absolutely amazing <a href="https://www.openbsd.org/">OpenBSD</a> project.</p> <div id="outline-container-headline-1" class="outline-2"> <h2 id="headline-1"> TL;DR </h2> <div id="outline-text-headline-1" class="outline-text-2"> <p>The VPS provider is TierHive, the VPS has 1 vCPU with <del>512</del> 384 MB of RAM and 6GB of NVME disk space. This configuration costs about <del>$5.64</del> $4.56 per <strong>year</strong>. The operating system is OpenBSD, because for quite some time, I was curious about <a href="https://man.openbsd.org/httpd.8">httpd(8)</a>, which is one of the main reasons this VPS exists.</p>
