Shownotes
Social media services have largely become a marketplace designed to capture and hold your attention, rather than places where people share information and talk to one another. A large part of this is because they are hosted on large-scale platforms that must be paid for by large, centralized companies. NOSTR is taking a different direction, creating a protocol and system that can be hosted by anyone, anywhere, to build a social network. Wouter Constant joins Tom and Russ to explain what NOSTR is, and how it’s different.
You can learn more about NOSTR here.

Deploying AI for AI Ops, or even just for general use in your network, is very simple–but we often forget that these kinds of new technologies need to be governed. From privacy through cost, operators need to decide how to govern their AI deployments to control costs, ensure accuracy, measure productivity, and make certain these systems are being used effectively. Colin Cosgrove joins Russ and Tom to look at AI governance.

Most designers and operators default to carrying all traffic–including network management traffic–across the same paths as application data, or in band. Is this the right choice, or should operators seriously consider creating an out-of-band network just for network management? If you decide to build an out-of-band network, what are some of the considerations and lessons learned? Daryll Swer joins Tom and Russ to discuss.

We are often told that if engineers who don’t go “all in” on AI will be left behind. While there are a few voices who argue that AI can be a dangerous tool, impacting not only the quality of our work, but the very quality of our thinking skills. Doug Smith, a critic of using AI for engineering, joins this episode of the Hedge to argue the contrary view of AI.
What are the dangers of relying on AI?

As DNS is more widely used to distribute certificate information, proving ownership of a resource becomes more critical. The constant challenges required to prove resource ownership, however, increase delay in connecting or using a resource. DNS persists–as the name implies–creates a persistent connection between a resource and a certificate authority. Henry Birge-Lee, Michael Slaughter, and Shiloh Heurich join Russ and Tom to explain how this new record type works and it’s importance to DNS.

Synchronizing information across the Internet, at an initial glance, looks like a fairly simple problem to solve. Just copy a file to a host and create a magic protocol, right? Not really. Each kind of data has a fairly unique set of requirements–and RPKI data, used to provide security information for BGP, is no different. Job Snijders joins Tom and Russ to talk about ERIK, a protocol developed to synchronize RPKI records.
