Chasing why pulled me through three layers of misconfiguration: a rotated server certificate, a deprecated authentication method, and a hash protocol that&rsquo;s been on borrowed time for a decade. Permissive software would have kept me online without ever telling me any of this had happened.</p> <p>In a hostel with dense access-point coverage, roaming gets noisy. As you walk between buildings, the <em>supplicant</em> program on your device scans for the strongest signal and decides when to switch. Standing between several nodes all broadcasting <code>iitk-sec</code>, a supplicant like <a href="https://wiki.archlinux.org/title/Wpa_supplicant"><code>wpa_supplicant</code></a> will oscillate between them on marginal signal differences and degrade your connection. I had migrated my machine to <a href="https://wiki.archlinux.org/title/Iwd"><code>iwd</code></a> (iNet Wireless Daemon) to avoid exactly this, its <a href="https://www.youtube.com/watch?v=QIqT2obSPDk">newer roaming algorithm</a> is less twitchy.</p>http://epestr.com/blog/why-this-site-exists/Sun, 10 May 2026 00:00:00 +0000http://epestr.com/blog/why-this-site-exists/<p>This is the new site. It&rsquo;s two pages of content for book keeping, (<a href="http://epestr.com/">the long page</a> and <a href="http://epestr.com/resume/">the resume</a>) plus this place, which is where I&rsquo;ll write things down properly when I have something worth writing down.</p> <p>If you want to be told when one of those goes up, there is the <a href="../index.xml">RSS feed</a> being maintained.</p>
