- A new Linux kernel zero-day vulnerability affecting all 2.4/2.6 versions since May 2001 was disclosed; a patch was committed by Linus on 13 Aug 2009 (archived at http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=e694958388c50148389b0e9b9e9e8945cf0f1b98).  
- Rowan University’s follow-up paper on “cold fusion / LENR” was linked on NextBigFuture, prompting surprise and skepticism in the channel.  
- Intranasal stem-cell delivery research was discussed: low-intensity polarized light plus hyaluronidase tripled migration of ~300 k stem cells to rodent olfactory bulbs; full paper mirrored at http://adl.serveftp.org/papers/Intranasal%20delivery%20of%20cells%20to%20the%20brain.pdf.  
- SKDB (open-source hardware package manager) received multiple commits: fixes for Lego interface definitions, YAML parsing, screw-container metadata, and restored unit-test functionality.  
- DIYbio FAQ section on “open” science was criticized as poorly written, highlighting ongoing tension over community documentation quality.  
- Wake-on-LAN and remote-access security were debated: WoL only works over wired Ethernet, VNC encryption is “a joke,” and SSH port-forwarding recommended instead.  
- Practical fabrication links shared: MIT’s web-based Git design tools (http://fab.cba.mit.edu/content/tools/design/web/git.html), Lego bulldozer CAD tarball (http://adl.serveftp.org/lab/legos/bulldozer.tar), and Peeron Lego inventory (http://www.peeron.com/inv/sets/951-1).  
- Discussion of monetizing open biotech: QuantumG suggested offering wet-lab protocol services or kits to those lacking lab access, while kanzure sought concrete employment or revenue models.  
- Journal of Source Code for Biology and Medicine (http://www.scfbm.org/) was noted as a venue for publishing reproducible bio-scripts.  
- katsmeow prototyped a DIY positive-pressure respirator using Tyvek hood, aerosol cartridges, and battery fans for smoke-filled environments.
