I am the owner of lvh.me. And I'm glad to hear it's helpful. In truth, it's just a fancy DNS trick. lhv.me  and all of it's sub-domains just point back to your computer (127.0.0.1).  That means running ssl is as simple (or difficult) as running ssl on your computer.

I'm not sure how comfortable you are with the command line, but here's my how I setup my development environment. (rvm, passenger, nginx w/ SSL, etc).


# Install rvm (no sudo!)
# ------------------------------------------------------
bash < <( curl http://rvm.beginrescueend.com/releases/rvm-install-head )
source ~/.rvm/scripts/rvm
rvm install ree-1.8.7-2010.02

    // this return the url that redirects to the according user image/avatar/profile picture
    // implemented services: google profiles, facebook, gravatar, twitter, tumblr, default fallback
    // for google   use get_avatar_from_service('google', profile-name or user-id , size-in-px )

    // for tumblr   use get_avatar_from_service('tumblr', blog-url, size-in-px )
    // everything else will go to the fallback
    // google and gravatar scale the avatar to any site, others will guided to the next best version

To change a field name in django 1.7+

1.  Edit the field name in the model (but remember the old field name: you need it for step 3!)
2.  Create an empty migration
$ python manage.py makemigrations --empty myApp
3.  Edit the empty migration (it's in the migrations folder in your app folder, and will be the most recent migration) by adding

migrations.RenameField('MyModel', 'old_field_name', 'new_field_name'),

to the operations list.

How to make a globally available executable script in the scripting language of your choice

    which ruby
  

• Add that path as an interpreter directive (using #!) on the first line of your script. For example if you want to write a node script and which node returned /usr/local/bin/node, the first line of your script should be:
