• What does this Eclipse icon mean in a Merge Results view?

  I just did an svn merge from a branch to a trunk in my Eclipse IDE, and in the Merge Results view, there is this following icon: I am dying to know what it means.

• Why did Matz choose to make Strings mutable by default in Ruby?

  - by Seth Tisue

  It's the reverse of this question: http://stackoverflow.com/questions/93091/why-cant-strings-be-mutable-in-java-and-net Was this choice made in Ruby only because operations (appends and such) are efficient on mutable strings, or was there some other reason? (If it's only efficiency, that would seem peculiar, since the design of Ruby seems otherwise to not put a high premium on faciliating efficient implementation.)
