Four short links: 9 June 2011

MongoDB Subpessimalization, Anti-Intellectualism, Teen Internet Use, Android Internals

  1. Optimizing MongoDB — shorter field names, barely hundreds of ops/s when not in RAM, updates hold a lock while they fetch the original from disk … it’s a pretty grim story. (via Artur Bergman)
  2. Is There a New Geek Anti-Intellectualism?focus is absolutely necessary if we are to gain knowledge. We will be ignoramuses indeed, if we merely flow along with the digital current and do not take the time to read extended, difficult texts. (via Sacha Judd)
  3. Trend Data for Teens (Pew Internet and American Life Project) — one in six American teens have used the Internet to look for information online about a health topic that’s hard to talk about, like drug use, sexual health, or depression.
  4. The Guts of Android (Linux Weekly News) — technical but high-level explanation of the components of an Android system and how they compare to those of a typical Linux system.
