Four short links: 21 Jan 2009

In today’s edition: the spread of fake news, keeping track of your real power use, a Javascript library
and a less-than-impressed take on mobile location apps.

  1. Echo Chamber – the British tabloid The Sun posted a story that turned out to be fabricated. This site tracked that story’s spread and uncritical acceptance by other news outlets and web sites.
  2. Real Time Web-Based Power Charting – build the software and hardware to get a live chart in a web page that updates every 10 seconds with the instantaneous power usage for your entire house.
  3. ActiveRecordJS – just what it sounds like, ActiveRecord for Javascript. AR is a complex subsystem of Rails, and it’s interesting to see the functionality ported to Javascript.
  4. I Am Here: One Man’s Experiment with the Location-Aware Lifestyle – a reporter tries all the location apps, and discovers the future isn’t all here yet. Interesting: only three paragraphs of this long story are about the good bits of location services, the rest question its implementation, privacy, and utility.

DIY Appliances on the Web?

Or, My Enterprise is Appliancized, Why Isn't Your Web? I wrote a couple of posts a while back that covered task-optimized hardware. This one was about a system that combined Field Programmable Gate Arrays (FPGA's) with a commodity CPU platform to provide the sheer number crunching performance needed to break GSM encryption. This one looked at using task-appropriate efficient processors…

Africa's Energy Deficit: Energy Hacks Can Make A Difference

About six weeks ago I came across this quote from a Wall Street Journal article and I have been pondering it ever since: Africa has the capacity to generate about 63 gigawatts of power for roughly 770 million people — about what Spain produces for its population of 40 million. For most African countries, the World Bank estimates that universal…
