Outline

  • Who am I?
  • Purpose: Focus on ambitious projects, and leave nitty-gritty to automation and tools
  • Open Source.
    • How many of you have used open source software before?
    • How many of you have created or contributed to an open source application?
    • How many of you are thinking of making their project open source? Why not?
    • Advantages of Open Sourcing final year projects
      • It's a resume. Your work speaks for you.
      • Collaborating with your partners and others is easy
      • You get to use state-of-the-art tooling for free
  • Programming is like writing
    • Programming is writing detailed instructions for a computer to follow.
    • Most people focus on languages, tools, and frameworks instead of patterns and processes
    • Knowing English, how to type, and how to use MS Word is necessary to be a good writer, not sufficient.
    • What else is important?
      • Understanding of the problem at hand - Know what you are solving.
      • Communication - working on a team requires communicating your ideas and understanding other people's ideas
      • Design patterns - Many smart people before us have worked out efficient ways to solve certain problems. Why reinvent the wheel? "Those who do not learn history are doomed to repeat it".

### Principles of a good Web Application

#### 12 Factors ([https://12factor.net/](https://12factor.net/))

* Revision Control
* Explicit Dependencies
* Configuration in Environment
* Backing services are external
* Separate Build, Release, and Run stages
* Make application process stateless
* Export service endpoints via port binding
* Scale out by multiplying stateless processes
* Fast startup, and graceful shutdown
* All deployment environments should be as similar as possible
* Export logs to stdout/stderr
* Run admin tasks as one-off processes
