- Google and CWI Amsterdam announced the first practical SHA-1 collision (shattered.io); the channel discussed immediate implications for Git, Bitcoin, and general software supply-chain integrity.  
- Peter Todd’s SHA-1 “pinata” bounty was claimed, and kanzure circulated mitigation proposals such as dual-hash Git commits (SHA-1 + SHA-256) and opentimestamps for commit-level timestamping.  
- adlai highlighted a Nature Nanotechnology paper reporting the first synthesis of triangulene, a non-Kekulé hydrocarbon with an open-shell π-system that could serve as a spintronic trit (three-state spin qubit).  
- nmz787_w1 explored interferometric microfluidic velocimetry, describing plans to adapt a Fizeau interferometer for non-contact measurement of fluid speed—potentially valuable for medical infusion-rate monitoring.  
- maaku argued that academic papers should not count until independently replicated, and suggested university “core facilities” monetize idle equipment by offering cloud-lab services modeled on Transcriptic.  
- kanzure linked Vium’s standardized, sensor-rich mouse-cage platform as an example of automated in-vivo phenotyping that could be replicated by university vivaria.  
- A brief exchange on superconducting resonators noted that superconductors still exhibit capacitance, with references to RC time-constant discussions on Physics Stack Exchange.  
- Cloudflare’s memory-leak incident (“Cloudbleed”) was flagged as a cautionary tale for services handling sensitive bio-data or cryptocurrency keys.
