`mkdir` and `cd` at once

I am sick of mkdir dir_name; cd dir_name;
The solution (put this function in “.bashrc” or whatever shell config file you use):

_mkcd () {
       mkdir -p $1
       cd $1
}
# usage: _mkcd /tmp/dir_1/dir_2
# pwd will show: /tmp/dir_1/dir_2

Why Assembla free plan:

  • Subversion Hosting with Integrated Tickets
  • Trac and Subversion Hosting
  • Team Collaboration
  • Subversion Repository
  • Git with Integrated Tickets

P.S. If you are like me - spitting on GIT on a daily basis - Mercurial is included in the other plans.

the actual meaning of “Merry Christmas”

Comment 
import re
 
greeting = "Merry Christmas"
 
greeting_list = map(chr, [ord(i) - len(greeting) - 1 for i in greeting])
greeting_list = filter(lambda x: re.match('[a-z]|[A-Z]', x), greeting_list)
 
# greeting_list is set(['c', 'b', 'd', 'i', 'Q', 'U', 'Y', 'X'])
# the 1st 3 elements are not clear to me: c,b,d
# 'i' means 'I', 'Q' means 'question', 'U' means 'you', 'Y' means 'why', 'X' means 'Christmas'
# which makes the compound: 'I question you - why Christmas?'

Right?
