    &amp;quot;It&amp;#39;s a Superpower??&amp;quot; debuted today, and it&amp;#39;s very, very good. I laughed out loud so much, in ways nothing has really prompted me to do in ages. It&amp;#39;s good. Go in cold. Trust me. https://allmylinks.com/itsasuperpower

    I&amp;#39;m looking at https://dns-aid.org/ and https://datatracker.ietf.org/doc/draft-mozleywilliams-dnsop-dnsaid/ and not understanding why it doesn&amp;#39;t make proper use of conventional DNS-SD SRV records, insisting on inventing their own, AI-agent-specific thing.

    RE: https://hails.org/@hailey/116657391001259044 I&amp;#39;ve had a look at this, and I think this is the wrong way to look at things. rsync is load-bearing, mature, valuable software. It&amp;#39;s featureful, it&amp;#39;s complicated, it&amp;#39;s useful, and it&amp;#39;s everywhere. And it&amp;#39;s written in C.
