Random Thoughts Involving Computers

This is the output from a cool command I found on ones zeros majors and minors

history 1000 | awk '{a[$2]++}END{for(i in a){print a[i] " " i}}' \
| sort -rn | head
124 rake
106 svn
84 ss
36 cd
30 git
26 rm
26 ls
16 sc
10 mate
5 psql

How about you?

And, again from ozmm is the try command. I think I’m going to start adding this to my projects, seems really simple and helpful.

class Object
  ##
  #   @person ? @person.name : nil
  # vs
  #   @person.try(:name)
  def try(method)
    send method if respond_to? method
  end
end
