Human Infrastructure 458: Wi-Fi Design Evolution, IETF in Space, and More

THIS WEEK’S MUST-READ BLOGS 🤓

John Howard got a GPG error after a macOS upgrade. This post is his dive down the rabbit hole to figure out what went wrong and how to fix it. - Drew  

From device offsets to channel contention, Eva digs into three design changes in the Wi-Fi space that have caused her to adjust her default thinking when it comes to Wi-Fi design work. - Drew 

Job hunting has never been easy, and despite the utility of LinkedIn and the profusion of online job search sites, it’s probably harder than ever. Leon Adato weighs in with some thoughts to help frustrated IT job hunters retain a shred of their sanity. - Drew 

Geoff Huston offers a detailed overview of space-networking related sessions at IETF 126, including updates on the Delay-Tolerant Networking Group and the Bundle protocol, an initiative called “Taking IP To Other Planets (TIPTOP), a census of current and planned low- and medium-orbit satellites for broadband and other purposes, and more. BTW, Heavy Networking dedicated an episode to the Bundle protocol, which digs into the challenges of getting packets to and from objects in space. Listen here. - Drew

TECH NEWS 📣

Technology always moves faster than the law, and that seems to be the case with multiple instances of AI models escaping “containment” (such as it was) and breaking into third-party computer systems. As a non-lawyer, it seems clear to me that laws were broken and that the organizations that built and operated these AI models were negligent and thus responsible. However, this Tech Crunch article interviews actual lawyers and legal experts, and it turns out there’s more gray area than I thought. - Drew 

Industrial control systems manage critical infrastructure, such as public water and power systems, which makes them likely targets for malicious actors. While you may have heard of recent attacks against water and wastewater treatment facilities in Michigan, this article says six other US states reported incidents to the FBI in recent weeks. This article provides a good overview of the challenges of protecting local utility systems, how the Iran war increases the threat of attack against these systems, and how US political conflicts complicate possible solutions. - Drew 

In a related story to the one above, this article checks in on the DEF CON Franklin project, a volunteer effort to help provide technical information and resources to local water utilities. So far, the project has made a very modest impact. Given current events, perhaps that might change. - Drew
