- The channel discussed the Aaron Swartz indictment for downloading JSTOR articles; participants noted JSTOR’s public statement that it “claims no interest in pursuing a legal case,” and linked to the Pirate Bay torrent (6554331) seeded by Archive Team to redistribute the JSTOR data set.  
- A quick Fermi estimate concluded that the entire corpus of “accessible” scientific papers (~100 million documents at 0.5 MB each) would fit into roughly 50 TB, with biotech papers averaging closer to 1.2 MB because of scanned figures.  
- Participants compared two independently downloaded IEEE PDFs to test for per-user watermarks; the files were bit-for-bit identical, suggesting IEEE no longer embeds such marks, and they outlined a protocol (different accounts, locations, times) for future watermark-detection experiments.  
- Discussion turned to automated removal of obvious “DOWNLOADED BY IP …” margin text and XML metadata fingerprints; kanzure mentioned existing scripts and the need for steganography expertise to check for subtler hidden identifiers.  
- A new Science paper (DOI 10.1126/science.1202529) was highlighted showing that microglia actively prune synapses during normal brain development, challenging the older view that pruning is purely an intrinsic neuronal process.  
- kanzure released a minimal Android-debug-bridge (adb) script named droid2png.sh on GitHub Gist (https://gist.github.com/1105435) for capturing screenshots from Android devices.
