Everything You Wanted to Know About Synchronization But Were Too Afraid to Ask (PDF) — This paper presents the most exhaustive study of synchronization to date. We span multiple layers, from hardware cache-coherence protocols up to high-level concurrent software. We do so on different types of architectures, from single-socket — uniform and non- uniform — to multi-socket — directory and broadcast-based many-cores. We draw a set of observations that, roughly speaking, imply that scalability of synchronization is mainly a property of the hardware.
Raspberry Pi as Low-Cost Security Camera (Instructables) — $120 HD motion-sensing web-viewable security camera.
Inside YouTube’s Fame Factory (FastCompany) — great article about the tipping point where peer-to-peer fame becomes stage-managed corporate fame, as Vidcon grows. See also Variety: If YouTube stars are swallowed by Hollywood, they are in danger of becoming less authentic versions of themselves, and teenagers will be able to pick up on that,” Sehdev says. “That could take away the one thing that makes YouTube stars so appealing.”
Sherlog.js (Github) — Javascript error and event tracker application. Honestly, I have no idea if this is any good but the name is golden. I’m such a sucker.
