Thanks so much to Julieta Arancio, PhD from the #OpenResearchCommunityAccelerator (ORCA) for the fascinating @curioss Deep Dive on #OpenHardware.

This led to a great discussion on #MakerSpaces, #licensing for Open Hardware, building engagement and signposting to the communities who need these innovations the most.

"Yesterday, the software that powers Pebble watches was around 95% open source. As of today, it’s now 100%. This means that if Core Devices were to disappear into a black hole, you have all the source code you need to build, run and improve the software behind your Pebble."

"We’ve also published electrical and mechanical design files for Pebble 2 Duo. Yes, you can download the schematic (includes KiCad project files) ..."

AI initiatives often appear like the CIA's Simple Sabotage Field Manual.

Just gum up the works
Work slowly.
Throw sand in the wheels of progress.
Make it complicated.
Flood the zone
Firehosing & disinformation.
Interrupt constantly.

When possible, refer all matters to committees for “further study and consideration"

Contrive as many interruptions to your work as you can

Do your work poorly & blame it on others

A Spy’s Guide To Making Bad Decisions

How did the father of the CIA, William J. Donovan, recommend degrading an enemy institution's productivity? It’s simple – facilitate lousy decision-making.

Oooh, it's my time to leap into cybersecurity.

"Adversarial Poetry as a Universal Single-Turn Jailbreak Mechanism in Large Language Models"

"...Abstract

We present evidence that adversarial poetry functions as a universal single-turn jailbreak technique for large language models (LLMs). Across 25 frontier proprietary and open-weight models, curated poetic prompts yielded high attack-success rates (ASR), with some providers exceeding 90%. Mapping prompts to MLCommons and EU CoP risk taxonomies shows that poetic attacks transfer across CBRN, manipulation, cyber-offence, and loss-of-control domains. Converting 1,200 MLCommons harmful prompts into verse via a standardized meta-prompt produced ASRs up to 18 times higher than their prose baselines. ..."

What are your favorite books on repairing things? What about books on making things?

As the internet gets filled with AI slop I've been putting together a personal library for friends and neighbors.

I have a book on bike repair, two books related to making, altering, and mending clothes, a book on home repairs, a book about electronics, and the book I used to study for my Ham radio exam.

A great many interesting talks on open hardware and free silicon have been published.

NGI0 partner @fsi has published the video of the Free Silicon Conference 2025 talks.

The talks average between 15 to 20 minutes, providing a nice way to get up to date with the state of the art of free silicon.
