   Explanations for some books, movies and other mysteries of popular
   culture -- according to Wired.

   2. "Beethoven's Ninth Symphony of greater importance than technology",
      or, "Why CDs were originally limited to 74 minutes"
     <http://www.marantzphilips.nl/The_cd_laser/>
   "Philips engineers had always based their work on a playing time of an
   hour, a few minutes longer than a double-sided LP...  However, Sony
   vice-president Norio Ohga, who was responsible for the project, did not
   agree. 'Let us take the music as the basis,' ... Ohga had fond memories
   of Beethoven's Ninth Symphony. That had to fit on the CD... The longest
   known performance lasted 74 minutes."

   However, Snopes isn't convinced, giving the explanation the status of
   'Undetermined'":

   "Alone in a room in his home in Bonn, Germany, Friedhelm Hillebrand sat
   at his typewriter, tapping out random sentences and questions on a
   sheet of paper.  As he went along, Hillebrand counted the number of
   letters, numbers, punctuation marks and spaces on the page. Each blurb
   ran on for a line or two and nearly always clocked in under 160
   characters."

Getting Things Done + A Perfect Mess

   Recently, I read a couple of books that look at the idea of order and
   lack of it from opposing angles.  My struggle to do all the things
   that I wanted and/or needed to do prompted me to read the first,
   "Getting Things Done".  The second book, "A Perfect Mess", was a timely
   reminder that there's nothing wrong with a little disorder.  In fact,
   as long as your ability to work is not impaired, a bit of mess can
   actually be beneficial.

   1. "Getting Things Done: The Art of Stress-Free Productivity"
      by David Allen
     <http://www.amazon.com/Getting-Things-Done/dp/0142000280>

   "Getting Things Done", or GTD for short, is a an approach to task
   management.  According to the author, one of the obstacles to doing
   stuff is the knowledge of having a lot of other tasks to do.  So the
   idea is to move these "open loops" out of your mind and onto a list
   (actually several lists).  This allows you to concentrate fully on the
   task at hand, knowing that the other tasks have been safely captured
   elsewhere.

   Some basic principles underlie GTD: collection, processing, organising,
   reviewing and doing.  More detailed information about GTD is
   available on Wikipedia:
     <http://en.wikipedia.org/wiki/Getting_Things_Done>
   Also, a chapter-by-chapter summary is at:
     <http://www.wikisummaries.org/Getting_things_done>

   As I mentioned, there are usually many lists: "today", projects, next
   actions (for each project), "some day", etc.  Your tasks gather in an
   "inbox", which you check through regularly.  If it's a two-minute job,
   you might decide to do it right now (e.g. arrange an appointment).  Or
   you could delegate it to someone else.  All other tasks get added to the
   appropriate list to be done later.

   There's a lot of common-sense advice in GTD.  Many people keep lists to
   track their tasks.  I have in the past, but not to the extent proposed
   in the book.  The two-minute rule can help you deal with a lot of
   incoming request.  And the act of ticking or crossing off a completed
   task gives you a sense of accomplishment.

   But there's also a risk of obsessing too much about getting your life
   tightly organised.  If you plan each minute of the day, for example, you
   will not only spend a lot of time organising rather than doing, you can
   also pack your day with so many "tasks" that there's little room for
   spontaneity.  It's a bit like having such a busy itinerary on a holiday
   that you can't actually relax and enjoy yourself.

   GTD has its critics.  Some say it's too paper-centric with its lists,
   folders and filing cabinets.  Others say "GTD is more focused on doing
   whatever comes at you rather than doing what you should be doing -- the
   important stuff".  Some critics go so far as to suggest that it has the
   characteristics of a "cult".  You can read about these and other
   criticisms in: "What Is Wrong with GTD?":
     <http://www.whakate.com/lead-articles/what-is-wrong-with-gtd/>

   Overall, I've found many of the basic ideas of GTD useful.  However, I'm
   not a busy executive, so I found the full GTD approach a bit over the
   top.  Where applicable, I've tried to apply some of the techniques to my
   situation.  "Just enough" or pragmatic GTD has helped me organise the
   drudgery of my mundane tasks, freeing up time to concentrate on the
   things I'd rather be doing.  As long as I regularly check and prioritise
   my handful of lists, I won't get any nasty surprises when things
   suddenly fall due.


   2. "A Perfect Mess: The Hidden Benefits of Disorder"
      by Eric Abrahamson and David H. Freedman
     <http://www.amazon.com/Perfect-Mess/dp/0316013994>

   In some ways, this book is an antidote to the obsession with
   organisation and neatness that systems like GTD risk promoting.  The
   authors argue that far from being a problem, a "mess" can provide many
   benefits.

   The mere fact that I even found this book is the result of a bit of
   messiness.  While in the library looking through the shelves for
   something else, I noticed the book sticking out.  Had it been neatly
   arranged in it's proper place, I probably wouldn't even have noticed it!

   The immediate benefits of accepting mess in our lives are the time and
   effort saved not making everything neat and tidy.  But the authors go
   further, suggesting other, less obvious benefits.  For example, a little
   bit of desk clutter can lead to chance associations.  Serendipity and
   creativity can result when two or more seemingly unrelated items in a
   pile come to hand.  In the home, a little mess can provide warmth and a
   lived-in feel.

   The authors provide other specific examples to back up their case.
   Apparently, penicillin was discovered thanks to a messy laboratory.
   Alexander Fleming had left some old, contaminated specimens lying around
   which later lead to the discovery that mould could act as an antibiotic.
   Then there's a quip attributed to Albert Einstein: in response to the
   criticism that "a cluttered desk is a sign of a cluttered mind", he's
   reported to have said: "then what are we to think of an empty desk?".

   But the authors do not advocate total chaos.  If things are so
   disorganised that you can't even move around or use your desk, then
   you've got a problem.  Rather, they argue that everyone has an "optimal"
   level of mess.  They suggest a stepwise approach to finding the "right"
   level of mess: try introducing a little mess (or tidiness) to see if it
   improves your situation.  If it does, try a little more.  Stop when no
   further improvements can be made.

   Overall, I enjoyed reading this sometimes tongue-in-cheek book.  The
   only major criticism I have is that the references section is not as
   comprehensive as it could be to back up the arguments.
