(And yes, sharp-eyed readers will notice a family name shared by Alexis and Melina). After interviewing many guests about their tech journeys, our hosts share their own personal... Read more »

Vibe coding: give AI a description of what you want, the model writes the code, you ship it, and then you hope for the best. It works great for side projects, but it can fall apart the moment you point an AI agent at production infrastructure. Today, William and Eyvonne sit down with John Capobianco,... Read more »

Eric Chou is joined by Matt Campbell, a seasoned network engineer whose career has taken him into some of the most demanding and high-stakes environments around. Together they’ll explore how Matt’s automation philosophy, lessons learned, and best practices adapt when the margin of error is razor thin. Whether you’re automating basic configs or tackling brownfield... Read more »

The best strategy in the world won’t succeed if a team falters operationally. But what is operational excellence, and what does it take to acquire it? Cal Poly faculty member (and former Intel strategist) John Miranda shares his thinking with our Heavy Strategy listeners.

In the cybercrime industry, initial access brokers specialize in break-ins. They pick digital locks and slide open electronic windows, and then sell that access to other threat actors who specialize in ransomware, exfiltration, and other crimes. SocGholish is a widely used tool in the access broker toolkit. Typically disguised as a legitimate software update, SocGholish... Read more »

Today our hosts discuss the essential role of Stateless Address Autoconfiguration (SLAAC) in successfully deploying an IPv6-mostly network. SLAAC is required to assign a unique IPv6 address to the Customer-side Translator (CLAT), which allows devices to operate on IPv6. However, enterprise operators might prefer using DHCPv6 for network tracking and accountability, potentially trapping them in... Read more »

Lenny Giuliano, Sr. Distinguished Systems Engineer at HPE Juniper Networks, joins Holly and Ethan for another round of multicast. Part two helps fill in details not covered in episode 50. They cover how multicast traffic also affects Ethernet frame addressing, and the key differences between IPv4 and IPv6 multicast. They also explain new hybrid multicast... Read more »

Ned and Kyler discuss the state of platform engineering, DevEx, and how AI is affecting choices in those domains with guest Annem Shah. They discuss how AI can help bridge the gap between initial setup and continuous operations by providing feedback and interpreting complex error messages. They also break down how AI can assist in...
