7. What is Programming?
Definition courtesy of Wikipedia:
Computer programming (often shortened to programming) is the comprehensive process that leads from an original
formulation of a computing problem to executable programs. It involves activities such as analysis, understanding, and
generically solving such problems resulting in an algorithm, verification of requirements of the algorithm including its
correctness and its resource consumption, implementation (or coding) of the algorithm in a target programming language,
testing, debugging, and maintaining thesource code, implementation of the build system and management of derived
artefacts such as machine code of computer programs. The algorithm is often only represented in human-parseable form
and reasoned about using logic.
Programming is:
Analyzing a problem, determining a solution
Translating the problem and solution into a computer language
Finding and fixing errors that come up translating the problem and solution

8. What is Development?
Definition courtesy of Wikipedia:
Software development (also known as application development, software design, designing software, software application
development, enterprise application development, or platform development) is the development of a software product. The
term "software development" may be used to refer to the activity of computer programming, which is the process of
writing and maintaining the source code, but in a broader sense of the term it includes all that is involved between the
conception of the desired software through to the final manifestation of the software, ideally in a planned and structured
process. Therefore, software development may include research, new development, prototyping, modification, reuse, re-
engineering, maintenance, or any other activities that result in software products.
Software Development is:
Computer programming plus all other activities that go into producing a
fully functional software system
This is not what we are doing in this class

9. What is Source Control?
Data is recorded on who did what and when with a project
Comments are also set to notate changes that were made
Project files can be compared, restored or merged from any point
Multiple collaborators can work simultaneously and tracks
Friday, August 30, 13
10. Github
Find, follow, contribute, pull and fork projects that you find
interesting or that are useful to you
Publish projects that others might find interesting or useful
Collaborate in a group on projects with simple notation
Keep backups of work in a safe place

13. Creating Your Accounts
Github Account:
Open https://github.com/signup/free
Use your Valencia email address, but others can be added
Find and follow the Github organization for this class
Cloud9 Account:
Open https://c9.io/site/sign-up-for-free/
Use your Github account to create your Cloud9 account
Create a new Workspace and call it “sandbox”
Friday, August 30, 13
14. Set Up Your Workspace
Create a new Repository in Github called “assignments”
Create a Workspace in Cloud9 from this new repo
Open your Workspace and create a file named “README.md”
Enter the following in that file, then save:
name: Your Name
class: DIG1108C, Fall 2013
Use the console to “git add” and “git commit” your file
Use “git push origin master” to send the file to Github
Friday, August 30, 13
16. Exploring Your Tools
Part 1:
Find the Github account for this class (vc-dig1108-fall-2013)
Find the repository for the syllabus
Sign up for change notifications by “watching” the repo
Part 2:
Find an interesting project on Github, preferably small
Research the project and prepare to explain it in Class Two
Copy (“fork”) the repo into your own Github account
Create a workspace in Cloud9 for this new repository
