Weekly summary of the Discursive Podcast
Some of you already know I’ve been experimenting with podcasting this week — trying to see if it’s something worth doing. I’ve recorded seven episodes so far, and I’d love to hear what you think. Leave a comment here or reach out on LinkedIn; I genuinely welcome feedback. I’ve put together a summary of this week’s episodes, along with my daily news segment — where each day I cover one security story, one programming story, and one from what I call the “weird” bucket. It’s been fun getting back into this rhythm, revisiting a medium I’ve worked in before, and finding a groove that feels like home again. My goal is simple: to make something worth listening to — a podcast that talks about technology like adults do. Not pop science, not surface-level hype, but honest discussions about how technology shapes us and how.
If you listen and have thoughts, please share them. This project will stay technical — it might overwhelm some listeners who aren’t deep in the space — but I’m working to slow down and explain more as I go. Let me know what topics you’d like to hear next.
TORCHLIGHT, a research tool presented at USENIX Security 2025, discovered 29 zero-day exploits affecting 12.71 million IoT devices hidden on the Tor network by analyzing 26 terabytes of traffic over twelve months. These aren’t just smart fridges—they’re industrial controllers, security cameras, and network equipment that control critical infrastructure, now potentially compromised by untraceable attackers. The programming language Frink treats units of measurement as first-class citizens in its type system, preventing the kind of unit conversion error that destroyed NASA’s Mars Climate Orbiter in 1999. Created by Alan Eliasen in 2001, it’s been quietly used by engineers for over 20 years when precise unit tracking is critical. The Vera C. Rubin Observatory in Chile activated the world’s largest digital camera (3,200 megapixels), discovering over 2,000 new asteroids in just its first 10 hours of operation — representing only 0.05% of its goal to map 20 billion galaxies.
This week’s episodes covered substantial ground in technical territory. We explored how open source evolved through distinct decades, culminating in the argument that Git fundamentally changed power dynamics by making forking trivial. We examined the legal complexity developers face with generative AI tools, including the gray areas around feeding output from one model into another. The passionate defense of code longevity challenged “rewrite culture,” using examples of 1970s Fortran code still running today because it was validated and works. Dijkstra’s 1972 Turing Award lecture proved eerily prescient about 2025 AI anxiety, predicting that better tools just let us tackle more complex problems. The FinOps deep dive explained why utilization reports without context are useless — sometimes, low utilization is a feature, not a bug. And the week ended with a nuanced take on DHH’s cloud exodus, defending his decision while outlining the crucial complications most teams must consider.
Additional stories include Apple being found guilty of App Store dominance abuse in the UK, Myanmar’s military shutting down a massive online scam operation seizing Starlink terminals, and California State University partnering with Amazon, OpenAI, and Nvidia to become America’s “first AI-empowered university.” The common thread throughout the week: technology decisions rarely have simple answers.
