I let GPT + Opus build a wearable toy product from a paper sketch

I wanted to build a personalized PCB badge for DEF CON, just for the heck of it. I’ve built wearable PCBs before, but this time I wanted to give LLMs a go. LLMs successfully designed hardware and firmware entirely, with human guidance, although they failed at detecting a loop between nets.

My Takeaways from The Real World AI Security Conference at Stanford

Ai security

The security industry is catching up fast to AI agents. Most current work focuses on securing agents rather than using AI for security. Here are my takeaways from the first Real World AI Security conference at Stanford.

Become a Cybersecurity Supercommunicator

Communication , Security

This is the second post in a series on how to design, debug, reverse engineer, and deliver talks that land with impact in the high-stakes world of cybersecurity.

Cybersecurity Needs Supercommunicators

Communication , Security

This is the first post in a series on how to design, debug, reverse engineer, and deliver talks that land with impact in the high-stakes world of cybersecurity. At the end of each post, you’ll find a ‘How to Coach for This?’ section.

CPU Silicon Security Research and Fuzzing (RISC-V)

Hardware , Silicon , Security

I’ve embarked on a brief journey to learn RISC-V and I ended up finding a niche of interesting material on security research on fuzzing, so I pivoted my attention to that. Here’s a brief summary of what I found.

Steam , Arduino , Maker

My son was asked to build a compound machine as science project. The machine is expected to dispense cards as a way to celebrate Valentine’s Day with classmates. I decided to “STEM+ the heck out of this project” and involve my son to let him practice with logic and fine manipulation skills.

Intel Alder Lake Leak Checker

Firmware , Platform , Security

Yesterday, the news broke that firmware code leaked from Lenovo, which included Intel Alder Lake reference code. While I leave you to this great post by Binarly.io’s REsearch team for the details, I want to focus on how to check if firmware images are affected.

Information and Cyber Security News Feeds

Communication , Security

I want to release my very personal and opinionatedly organized infosec/cybersec sources in one OPML file. I don’t know to what extent I’ll be able to curate it, but for now I wanted to get it out.

Scalable, Hand-curated Newsletters: A Data-centric, Automatic Workflow

Communication , Content curation

I guess it’s not unique to the cyber-security world, but research and media move pretty fast here, so it’s easy to end up with hundreds of seemingly interestingly articles or blog posts to read every day. Of course, that’s not humanly possible. Let me tell you how I deal with this.

Masked Emotions

Psychology

Despite this little beast known as COVID-19 pandemic is about to turn 1 year old, many people still feel strange when wearing masks. While wearing a face mask we can’t speak properly and we can’t see others’ mouth, so our experience of a conversation can change, especially if speaking is central in our lives (think of any public figure). Wearing a face mask impacts how we perceive others’ emotions as well as our emotions (how we feel). Because our own understanding of our emotions can also influence such emotions in a continuous feedback loop, the effect can go beyond how we feel in that particular moment.
