5. Terms / definitions for today
- git – command line version control system
we’ll experience this the most today
- FOSS – Free, Open Source Software
Free is important since things could be
open source yet not actually be free use
- Markdown / MD – text annotation /
enhancement via simple character
association surrounding text
- SaaS – Software as a Service, a platform
offering methodology where users get
access to software and pay in a service
oriented manner

6. Who’s using Git / Alternatives
- Not everyone.. But basically everyone
- Subversion / SVN is an alternative
version control system
- Github’s ease of use + Linux using git
really caused it to take off
- Replication / stability in large networks
or decentralization of approaches also
benefits git

8. Who uses git in their day to day
- DevOps / sys admins – for configuration
or automation files
- System programmers – per change or per

- Front end – JavaScript / HTML files
- Designer – CSS / images / graphics
- Managers – Typically just via code
management platforms like github / gitlab

9. Gitlab
- Github is NOT open source itself
- Github SaaS USED for FOSS hosting
- GitLab Open source alternative + SaaS
- Gitlab provides similar capabilities and
ripped off many of its features as open
- Github advantage
- free service, can pay for more features
- private repos / unified dev
- owned by Microsoft (as of 2018)
- Gitlab advantages
- can run internal to organization
- advanced CI workflow capabilities
- Organizational logins (PSU uses this)

11. Why Github “won” for most FOSS projects
- https://desktop.github.com/
- Desktop apps for all platforms to make
git visual / approachable
- github repos themselves are very clean
- easy to “see” where you are in code
- Many languages visualized / color coded
in browser
- Able to click “edit” on any file and
modify it in browser and make “commit”
- Issues / Pull Requests / Releases
- Organizes process of code organization
- ”PR” / “Fork” workflow is amazing
- Release management / “tag” easy to view

17. Project Health
As part of an “Incubation process” with
Apereo Foundation I had to add several
things required for a healthy software
project.
Let’s look quickly at some of those as they
can be relevant to any project on github.
