# 30 minutes Lisp in Ruby
# Hong Minhee <http://dahlia.kr/>
#
# This Lisp implementation does not provide a s-expression reader.
# Instead, it uses Ruby syntax like following code:
#
#     [:def, :factorial,
#       [:lambda, [:n],
#         [:if, [:"=", :n, 1],
#               1,

Git Workflow

Basic workflow I've been following, inspired by the RailsTutorial website.

Branch -> Edit -> Commit -> Merge -> Push

git init        => Create a new repository in the current directory

git add         => Add file to current changeset.

Mercurial Workflow

Clone -> Edit -> Commit -> Push -> Update

hg clone http://bitbucket.org/repo        => Clone a remote repo

hg clone project_dir new_changes_dir      => Clone a local repo

hg commit -m "Message"                    => Commit locally changed files.

Programming Achievements: How to Level Up as a Developer

1. Select a particular experience to pursue.
2. Pursue that experience to completion. (Achievement unlocked!)
3. Reflect on that experience. Really soak it in. Maybe a blog post would be in order?
4. Return to Step 1, this time selecting a new experience.

This gist is a fork of the gist from this blog post.
