一花一世界

如果你是文科，你应该看看理科的思维。如果你是理科，你更应该看看Internet RFC1925 (The Twelve Networking Truths):

http://www.faqs.org/rfcs/rfc1925.html

摘录如下，我喜欢的地方都标粗了:

1. Introduction

   This Request for Comments (RFC) provides information about the fundamental truths underlying all networking. These truths apply to networking in general, and are not limited to TCP/IP, the Internet, or any other subset of the networking community.

2. The Fundamental Truths

   (1)  It Has To Work.

   (2)  No matter how hard you push and no matter what the priority, you can't increase the speed of light.

        (2a) (corollary). No matter how hard you try, you can't make a baby in much less than 9 months. Trying to speed this up *might* make it slower, but it won't make it happen any quicker.

   (3)  With sufficient thrust, pigs fly just fine. However, this is not necessarily a good idea. It is hard to be sure where they are going to land, and it could be dangerous sitting under them as they fly overhead.

   (4)  Some things in life can never be fully appreciated nor understood unless experienced firsthand. Some things in networking can never be fully understood by someone who neither builds commercial networking equipment nor runs an operational network.

   (5)  It is always possible to aglutenate multiple separate problems into a single complex interdependent solution. In most cases this is a bad idea.

   (6)  It is easier to move a problem around (for example, by movi

ng the problem to a different part of the overall network architecture) than it is to solve it.

        (6a) (corollary). It is always possible to add another level of indirection.

   (7)  It is always something

        (7a) (corollary). Good, Fast, Cheap: Pick any two (you can't have all three).

   (8)  It is more complicated than you think.

   (9)  For all resources, whatever it is, you need more.

       (9a) (corollary) Every networking problem always takes longer to solve than it seems like it should.

   (10) One size never fits all.

   (11) Every old idea will be proposed again with a different name and a different presentation, regardless of whether it works.

        (11a) (corollary). See rule 6a.

   (12) In protocol design, perfection has been reached not when there is nothing left to add, but when there is nothing left to take away.

其实，这些都是放之四海而皆准的真理。强调的是平衡，取舍，双赢。文科跟理科，殊途同归。

滴水含沧海，一叶知春秋
