2. Abstract
   Russ Cox said “Software engineering is what happens to
   programming when you add time and other programmers”.
   André Gomes in his presentation will show you how GitLab
   CI/CD can help you to advance from programmer to software
   engineer by integrating and delivering software, including, but
   not limited to Python packages.

6. Programming, Time and People
   Being agile and releasing often matters.
   Testing matters.
   Code readability matters.
   Software development is a social effort that needs to me managed
   over time.

8. Less jargon, please!
   CI/CD can be thought of as Happy CommIting!
   Pushing changes to a remote repository triggers safety belts, such
   as:
   does it pass the tests?
   does it compile?
   is the code properly formatted?
   . . .

9. Cool, but how to. . . ?
   Today we will be looking at GitLab CI/CD.
   "Safety belts" are stages.
   A set of stages is a pipeline.

10. Demo
    Let’s start simple and fast forward boring steps.
    Here’s the source code of a Hello World program (Python).
    Here’s the yaml file.
    Here are the pipelines.

11. Conclusions
    Managing time and the social side of software development is key!
    A CI/CD mindset sets you apart from being just a programmer.
    Start integrating and deploying those python packages!
