- KrakenSDR’s open-source passive-radar code was abruptly removed after an IEEE Spectrum article drew ITAR scrutiny; the community immediately advised “git clone while you can” and pointed to existing forks.  
- Two open Python libraries for passive radar were shared: APRiL (Amalinda/APRiL) and the KrakenSDR-specific krakensdr_pr repository, both still mirrored on GitHub.  
- Participants noted that bistatic passive radar can be built with only two inexpensive RTL-SDR dongles synchronized by sharing a single 28.8 MHz clock (one crystal removed, a wire jumper added), eliminating the need for multi-channel boards.  
- A practical tutorial and code for dual-RTL passive radar are hosted at dopplerfish.com/passive-radar, with additional examples from the KAIRA project using 16 dual-coherent RTL-SDRs.  
- Beyond GNU Radio, SoapySDR was highlighted as the other major SDR framework; recent maintenance was observed to be by the son of the former GNU Radio lead.  
- A supply-chain warning circulated about malicious PyPI packages named “ipyhton” (misspelled) that inject JavaScript to hijack cryptocurrency addresses copied in the browser.  
- Dana Sibera’s fictional retro-tech hardware art was spotlighted via a Hackaday profile, illustrating imaginative devices that never existed but inspire open-hardware thinking.
