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

Pi + DeepSeekV4 is next-level stuff folks.

"NVD is deprioritizing, EUVD is nascent but may go the same way, and other CVE programs, such as MITRE, have had funding scares." "That era is officially over." - way to go @nistcybersecurity.bsky.social www.aikido.dev/blog/nist-nv... by @campuscodi.risky.biz news.risky.biz/risky-bullet...

NIST will no longer enrich most CVEs. Here's what changes, what breaks, and what comes next.

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] ⬇️

Part 2 dropped. 🧵[1/2] tl;dr: your slides are not your talk. skip the template skip the agenda (no spoilers) skip the "about me" ego slide 💣 start from the LAST slide: your 280-char core message 😱 then work backward. Full framework + slides ...

Let's see how much this will cost...

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.

Moved to claude-haiku-4-5-20251001 as my local GPU was suffering. Result isn't bad at all. Will have to tweak the prompt to get it to spit out: - 1 TL;DR topic sentence - 3 keywords - 3 top topics

I’ve had to fight with the ego of the author for the first 20% of the book. I’ve thought about dropping it a few times, but I’m glad I didn’t. The second half of the book is really inspiring.

I’ve been teaching my daughter how to solder and after we’re done with this last week, my wife reported that my daughter had a boost in her math scores. The stolen calculator is now back among the other assembled soldering kits.

Dedicated to all the folks at the defcon.run club. Next year we should bring defcon.run at @nohatcon.bsky.social strava.app.link/42XOKaJCyXb

🖥 No Hat 2025 lands in 📍 Bergamo, Italy - Oct 18! 1 day, 17 talks & workshops on Cybersecurity, AI, Cloud Security & Hacking. 🎤 Keynotes: @k8em0.bsky.social & @phretor.bsky.social 🔗 Full program nohat.it/agenda

Hey, you guys, look at this. Hey, you guys ever heard of this guy? Okay it says, "Chester Copperpot: Missing while in pursuit of local legend. Reclusive scavenger claims, 'I have the key to One-eyed Willy'." Whoa, do you guys realize what we could do?

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...

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-...
