How to have local versions of tracked config files in git

This is a fairly common question, and there isn't a One True Answer.

These are the most common techniques:

If you can modify your application

muxcmux

def valid? version
  pattern = /^\d+\.\d+\.\d+(\-(dev|beta|rc\d+))?$/
  raise "Tried to set invalid version: #{version}".red unless version =~ pattern
end

def correct_version version
  ver, flag = version.split '-'
  v = ver.split '.'
  (0..2).each do |n|
    v[n] = v[n].to_i

Move your stashes from one repo to another

---

This was useful for me when we created a new branch for a new major release, but were still working on our current version as well. I cloned our repo again and kept the new project on our new branch, but also wanted to get my stashes there.

Download your stashes

git stash show -p > patch

You'll have to specify your stash and name your file whatevery you want. Do this for as all your stashes, and you'll have patch files in your pwd.

# As of Nginx 1.7.5, add_header supports an "always" parameter which

# Question:

  # Suppose you have an array of 99 numbers. 
  # The array contains the digits 1 to 100 with one digit missing. 
  # Write four different algorithms to compute the missing number. 
  # Two of these should optimize for low storage and two of these should optimize for fast processing.
  # (Keep in mind, there are no duplicates and the array is not already sorted.)
