- A new high-resolution imaging paper on dendritic spines was shared: http://biorxiv.org/content/biorxiv/early/2015/03/11/016329.full.pdf.  
- Nick Johnson previewed an upcoming Kickstarter for an Arduino-compatible DDS signal-generator/frequency-counter board built around the low-cost AD9838 instead of the more expensive AD5932, using a TCXO for stability.  
- Discussion of frequency references compared TCXOs, OCXOs, and rubidium modules; rubidium units were noted to be “dead cheap” and glow purple when opened.  
- Google announced the shutdown of Google Code; participants worried about link-rot, loss of abandoned projects, and the risk of GitHub becoming the next centralized point of failure.  
- GitLab was criticized for paying to shut down the AGPL-licensed Gitorious and for offering a crippled “community edition,” prompting calls for decentralized or self-hosted alternatives.  
- Georgia Tech, Udacity, and AT&T launched an accredited $7 k online-only M.S. in Computer Science delivered via MOOCs: http://www.omscs.gatech.edu/.  
- Burke Labs’ automated small-molecule synthesizer using MIDA-boronate handles was highlighted (Science 347:1221), with Popular Mechanics framing it as a “chemistry 3-D printer.”  
- NASA data loss was cited: large portions of the NASA Technical Reports Server disappeared in 2013, illustrating the fragility of even government-hosted archives.  
- Participants lamented the absence of a universal, hash-addressed archive for all git objects, noting that every commit hash should be retrievable like a torrent magnet link.
