5-digit year usage minimizes the 10K-years problem. We had a 2-digit year problem when we went from year 1999 to year 2000. 5-digit year usage handles year 9999 to year 10000 problem.

Learning About Bitcoins open source P2P digital currency

Bruce Schneier on 9 April 2013.

   "I'm often asked what I think about bitcoins. I haven't analyzed 
    the security, but what I have seen looks good. The real issues 
    are economic and political, and I don't have the expertise to 
    have an opinion on that." -- Bruce Schneier

(1) Schneier saying security "looks good" is good for bitcoins.
(2) Who are the experts when it comes to the "real issues" of bitcoins?

I'm taking a break from Bitcoins now that Paul Krugman was written about them at the New York Times. {[14 Apr 2013] Antisocial Network} Note: I'm not a Paul Krugman fan, nor do I give a foo about the New York Times.

3-D Printing

From President Barack Obama's 2013 State of the Union address given on 12 February 2013.
   "There are things we can do, right now, to accelerate this trend.  
    Last year, we created our first manufacturing innovation institute 
    in Youngstown, Ohio.  A once-shuttered warehouse is now a state-of-the 
    art lab where new workers are mastering the 3D printing that has the 
    potential to revolutionize the way we make almost everything. There's 
    no reason this can't happen in other towns.  So tonight, I'm announcing 
    the launch of three more of these manufacturing hubs, where businesses 
    will partner with the Departments of Defense and Energy to turn regions 
    left behind by globalization into global centers of high-tech jobs. And 
    I ask this Congress to help create a network of fifteen of these hubs 
    and guarantee that the next revolution in manufacturing is Made in 
    America." 3D Printing Overrated? Not at All, Says GE's Jeffrey Immelt

   "3-D Printing helps you make the product from the core up so you 
    have less waste. The tool is cheaper, the time is faster. If all 
    I thought 3-D Printing could do was shoes, I wouldn't be talking 
    about it."--Jeffrey Immelt #AdditiveManufacturing Printing On the Micrometer Scale

   "With this printer, smallest three-dimensional objects, often smaller 
    than the diameter of a human hair, can be manufactured with minimum 
    time consumption and maximum resolution." #Nanoscribe Printing with metal: The final frontier of additive manufacturing 3-D Print With Human Embryonic Stem Cells

   "Technology: 3D printing and tissue engineering now allow bioprinting: 
    the design and fabrication of three-dimesional tissues. The meat created 
    in this process could be carefully designed to have the same mouth feel, 
    texture and flavor as traditional meat." #BioPrinting printing and tissue engineering

   "[...] the two-year-old who once could not lift her arms is now 
    able to play, color and feed herself. Printing the parts also 
    solves another major issue -- Emma is growing... quickly. The 
    adorable tot has already outgrown her first vest, but her mother 
    just calls the Nemours/Alfred I. duPont Hospital for Children and 
    has a new one made. The same goes for replacement parts. Should a 
    hinge or brace break, it need only be a matter of hours (not days 
    or weeks) before a new one is delivered." -- printed 'Magic Arms' give a little girl use of her limbs

   "I always wondered what it would be like to have custom shoes,"
    says Bolas. "They gave me a much more natural feel, with a perfect 
    balance between the flex of the sole and still the responsiveness 
    of a stiffer plate." --
Update::2013.03.07 Printed Keyboard with Working Keys!

   "A functional keyboard prototype featuring keys that depress 
    in a similar fashion to a real keyboard. This entire keyboard 
    was 3D printing in a single print job - with no assembly of 
    the keys into the board required."

   "3-D Printing (also know as Additive Manufacturing) is where a
    physical object is created from a virtual 3D model by laying
    down successive layers of materials." --

21 January 02013

This is the 47th edition of the MOTD. The Fall 2012 MOTD has been added to the MOTD archive.

The MOTD blog was named after the /etc/motd file used on Unix systems. Unix systems are multi-user systems and SysAdmins use the /etc/motd file to communicate messages to users upon log in.

I should let the MOTD die, but I can't. This 15-year-old blog could be deleted using one command-line: rm -rf $motd

The MOTD suffers from a severe case of linkrot (i.e. broken hyperlinks), but from day one the MOTD was considered a WORM (Write Once Read Many) resource. What you read on the MOTD is what I posted and the linkrot provides a picture of just how much the WWW has changed over the last 15+ years.
