- Discussion of Chris Tarnovsky’s Xbox 360 security-bypass attack using an ion-beam workstation and a mechanical probe station to position nanoscale needles on individual chip wires, illustrating the intersection of semiconductor reverse-engineering and open-hardware hacking.  
- Clarification that “nodes” in probe-station terminology refer to any XY point of interest—typically metal interconnects rather than single transistors—highlighting practical micro-probing techniques for security research.  
- Link to a 2018 AMA Journal of Ethics article on “Justice in CRISPR-Cas9” that critiques under-representation of minorities in genomic databases and warns of inequitable access to future somatic gene therapies, prompting debate about ethics versus therapy development priorities.  
- Sharing of four key speculative-execution attack papers: SgxSpectre (exfiltrating Intel SGX secrets), ExSpectre (hiding malware inside speculative paths), NetSpectre (reading memory over the network), and a systematic survey of transient-execution attacks and defenses.  
- Posting of MinimalFab (https://www.minimalfab.com/en/), a low-cost semiconductor prototyping platform demonstrated in an accompanying YouTube video, as a potential open-source route to small-scale IC fabrication.  
- Addition to the diyhpluswiki of a transcript comparing hardware cryptocurrency wallets from the Austin Bitcoin Developers meetup, expanding open-source secure-hardware resources.
