• How long is a CS degree good for?

  - by Recursion

  I came upon a comment on another forum today and one user responding to another suggested that a CS degree is really only good for one through two years at the most, and after that its as if you never had it. Is this really true? is this what employers think? When I did CS I never learned anything new, we learned fundamentals like data structures, algorithms, time complexity, OS fundamentals, language characteristics. Most of this stuff has been around for the past 20 years or so.

• Globbing in `git checkout`

  - by yar

  Is there any way to implement globbing in git checkout? It would be great to be able to use git checkout re* or even to have tab completion in the shell. I'm using zsh, but an answer that is shell independent would be great. Note: I realize that this is kind of a pipe dream, so... if I needed to implement this myself, must it be done in the shell language itself, or could it be done in, say, Ruby?

• _REQUIREDNAME always nil

  - by Nali4Freedom

  I'm trying to use the method for naming a lua package after the filename mentioned here, however _REQUIREDNAME is never defined. For example I have these two files samplePackage.lua: print("_REQUIREDNAME: ", _REQUIREDNAME) return nil; packageTest.lua: require "samplePackage" And when I run packageTest.lua it outputs > _REQUIREDNAME: nil I also couldn't find any mention of _REQUIREDNAME in the Lua 5.1 Refrence manual, so was this removed from the language, or am I missing something?
