Instagram's Architecture, New ssh, Android Economics, and Design Principles

  1. The Instagram Architecture (High Scalability) — great summary of the Instagram team’s post about the technology that runs Instagram. Lots of Python goodness in here.
  2. Mosh — ssh that lets you roam and stay connected. UTF-8 native.
  3. Android Economics — working back from Google’s declared valuation of Android royalties to figure out how much they have and how it’s growing. Error bars for Africa here, but can’t argue with the conclusion: Whereas Android generates $1.70/device/year and thus an Android device with a two year life generates about $3.5 to Google over its life, Apple obtained $576.3 for each iOS device it sold in 2011.
  4. UK Govt Digital Service’s Design Principles — if only everything in government followed Principle 1: Start with Needs (User Needs not Government Needs).
