  • Excellent investment advice.  Keep it simple...

    • There are 2 simple questions you must first answer:

      1. What is the time-frame in which you need access to your money? (next week? next year? 10 years? retirement?)

      2. How much risk and volatility are you comfortable with?

    • The Answer:
      Asset Allocation... not fundamental analysis, not technical analysis, not market
      trending, not tips from brokers and analysts ... but straight up asset
      allocation.

  • World Beta shares some links covering the endowment investing side of things...
    • A link to Frontier Capital Management - check out their knowledge section for more great papers similar to the ones Faber links to.
    • Faber mentions a great upcoming book covering the twelve top endowment CIO's .
    • from Alpha Magazine...Highbridge Capital Managment shares its office organization - putting traders and developers together.  I've always thought this would be a great idea in any shop.  By putting users and developers together - manual taks can be seen and automation can happen.

  • Online code review that works like a blog/wiki.  I wonder...is it possible to create a code review system similar to Mondrian within a source management toolset such as subversion?  Seems like most of the backend is there already...would only need to add some front end tools to display the changes being committed and allow comments on those changes.

  • Now, suppose that the array is of length n and only contains positive integers less than n. We can be sure (by the pigeonhole principle) that there is at least one duplicate.
  • So, how do we find the beginning of the cycle? The easiest approach is to use Floyd's cycle-finding algorithm. It works roughly like this: Start at the beginning of the sequence. Keep track of two values (call them ai and aj). At each step of the algorithm, move ai one step along the sequence, but move aj two steps. Stop when ai = aj.
