I wanted a PCB badge for @defcon.bsky.social just for the heck of it. I’ve done this before @kicad.org, but this time I wanted to give LLMs a go. I went through this with an open mind: I wanted to see what LLMs were capable of, while having a little fun. trustial.substack.com/p/i-let-gpt-...

I let GPT + Opus build a wearable PCB badge from a paper sketch
LLMs successfully designed hardware and firmware entirely, with human guidance, although they failed at detecting a loop between nets.

Dear paper authors, defining the formulas of TP, FP, F1-score and showing the CLI to call the Python script to run the experiment is a big, big turn off. Please, don’t do this in your papers. And if you really need to, use an appendix. 😕

The folks at @siderolabs.com made it a ONE line to secure booting a Talos Linux based Kubernetes node via PXE. No need to mess around with USB keys, even for small home setups it’s a breeze! Zero excuses for not enabling secure boot. ➡️ Start here factory.talos.dev

I just made my myself a little less necessary this year. I open-sourced an AI coaching skill that guides you (as I would do) during a 2-months speaker coaching session. Works with ChatGPT, Claude, Gemini, or any LLM — just load the prompt and start preparing. [1/2] ⬇️

Zotero just beats all bookmarking apps/services on customizability, storage, data control, price. $120/year for unlimited storage, when you save resources (e.g., websites, PDF), you get a local and remote self-contained snapshot on an actual file, and you can full-text search

I'm thinking of a good classification system. I prompted GPT 5.2 (w/ deep thinking) with the famous timeline by @xenokovah.bsky.social and a hint of some must-have labels, and it proposed an extension, which I like. Happy to hear any feedback.

Cybersecurity doesn’t just need brilliant minds. It needs supercommunicators—people who can turn complex ideas into clarity, urgency, and action. Here’s what I tell the speakers I coach for Black Hat 🧵 trustial.org/blog/cyberse...
trustial.org
Cybersecurity Needs Supercommunicators
The skills cybersecurity needs most? Deep experts who can clearly explain the balance between security risk and business priorities.

Today we’re studying variables with Python. Using containers to hold paper notes with values scribbled on them. Ideally operands should be of a different color, but I ran out of post-its 🙂‍↕️ Highly recommending “Python for Kids” by Jason Briggs. nostarch.com/python-kids-...

I am convinced 99% of websites should use magic links + passkeys. It bypasses all (debatable) portability objections to passkeys, it’s at least as secure as email-based recovery, as fast as a password manager, it’s available to all users… and importantly, no passwords!

Over the past 2 years I got used to Amazon Chime's auto-call functionality, which **calls** everyone 2 minutes before every meeting. To the point that I consistently miss all other meetings (e.g., Google Meet) that don't call me. Yes, I receive calendar notifications (multiple ones) but I miss them.
