  • Measuring money—the beer standard
  • "a beer standard is no more nor less arbitrary than a gold standard." Indeed, any number of different forms of commodity money have been used throughout history, including (according to Wikipedia) gold, silver, copper, salt, peppercorns, large stones, decorated belts, shells, alcohol, cigarettes, cannabis, candy, cocoa beans and barley, to name a few. http://en.wikipedia.org/wiki/Commodity_money

  • Don't send a man to do a meter's job
  • There is a bug in our commenting system that can cause comments to not appear if they include special characters (like smart quotes and apostrophes or other high-ascii characters). If you were trying to post a comment, please feel free to send the comment text to me (at rich.pell@ubm.com) and I will try determine the problem. Thanks.

  • Don't send a man to do a meter's job
  • Speaking of Soviet music synthesizers, there is a software simulator of the ANS ("Alexandr Nicolaevitch Skryabin") photoelectronic synthesizer ( http://www.ruskeys.net/eng/base/ans.php ), which can convert sound to images and vice versa: Virtual ANS: http://www.warmplace.ru/soft/ans/ It is available on most platforms, including iOS and Android.

  • Nanotech battery charges smartphone in 30 seconds
  • A quote from another article on the battery ( http://www.eetimes.com/document.asp?doc_id=1321873& ) suggests lithium-like discharge performance: "The battery's electrodes are based on multifunctional "nanodots" derived from bio-organic material, enabling both very fast supercapacitor-like charging on one side and slow discharge -- like a lithium electrode -- on the other."
