github recently switched to an https scheme as the default for cloning repos. as a side effect you may suddenly be prompted for a 'Username' and 'Password' when you push where, previously, you were able to do so without typing in credentials. the solution is to cause git to cache https credentials which is easy, since git uses curl under the covers

in your home directory create a file called '.netrc', for example

/Users/ahoward/.netrc

in it put these contents

#! /usr/bin/env ruby

  name 'gist'

  description <<-__

web apps nearly always end up needing a plethora of little javascript helper methods: you know, auto-complete forms, populating defaults, validations, etc.  these aren't API calls properly, just little tidbits of functionality needed to make the views work.

there is always a question of which controller to hang these methods off of.  do you make a global helper controller for all this stuff?  do you hang them off the controller in question?  how to do share the backend of javascript helper methods across controllers?

# fixes "# mesg: ttyname failed: Inappropriate ioctl for device" warnings when building docker
#
  echo '#! /bin/sh' > /usr/bin/mesg
  chmod 755 /usr/bin/mesg
  
 # all this does is replace the 'mesg' command with a no-op that always succeeds.
 # do this *early* in your Dockerfile somewhere.
 # from a security persprective this is also fine because it relates to multi-user unix systems,
 # not single user/contrained docker images.
