Four short links: 30 December 2011

  1. Hadoop Hits 1.0 -- open source distributed computation engine, heavily used in big data analysis, hits 1.0.
  2. Sparse and Low-Rank Approximation Wiki -- interesting technique: instead of sampling at 2x the rate you need to discriminate then compressing to trade noise for space, use these sampling algorithms to (intelligently) noisily sample at the lower bit rate to begin with. Promises interesting applications particularly in for sensors (e.g., the Rice single pixel camera). (via siah)
  3. Rise of Printer Malware -- firmware attacks embedded in printed documents. Another reminder that not only is it hard to write safe software, your mistakes can be epically bad. (via Cory Doctorow)
  4. Electric Circuits and Transistors Made From Cotton -- To make it conductive, the researchers coated cotton threads in a variety of other materials. To make conductive “wires,” the team coated the threads with gold nanoparticles, and then a conductive polymer. To turn a cotton wire into a semiconductor, it was dipped in another polymer, and then a further glycol coating to make it waterproof. Neat materials hack that might lend a new twist to wearables.

Top Stories: September 26-30, 2011

Here's a look at the top stories published across O'Reilly sites this week.

From crowdsourcing to crime-sourcing: The rise of distributed criminality
Crowdsourcing began as a way to tap the wisdom of crowds for the betterment of business and science. Crime groups have now repurposed the same tools and techniques for their own variation: "crime-sourcing."

Wearing Android on your sleeve
WIMM Labs believes that wearable technology and at-a-glance moments — things like looking at a thermometer and checking the clock — can create powerful combinations.

Fighting the next mobile war
While you'll likely interact with your smartphone tomorrow in much the same way you interacted with it today, it's quite possible that your smartphone will interact with the world in a very different way. The next mobile war has already begun.


Spoiler alert: The mouse dies. Touch and gesture take center stage
As touch and gesture evolve from novelty to default, we must rethink how we build software, implement hardware, and design interfaces.


Amazon's "Prime" challenger to the iPad
While conventional wisdom says that to compete with the iPad you must emulate Apple's best practices, Mark Sigal argues that Amazon can do just fine by blazing its own trail.
