The subject matter of the class
Chat with the person next to you and come up with about three items for each of the following.
Software design principles - What are principles that help you build good software? Software design practices - Primarily agile.
- Agile - Pair, refactoring, short sprints, client-focused, …
- DRY - A way of thinking about your code. (More generally, smells and ways to address them.)
- Patterns, particularly MVC, as a way of thinking about the architecture of programs.
- BDD and TDD - Approaching software development by thinking about capabilities.
- Testing - Why - Good software, understand legacy software, think about your goals in detail, free you to make changes.
- Acronyms: SOLID, SOFA, …
- User stories
Tools, particularly Ruby and Rails.
- Rspec for testing
- Cucumber for user stories
- Heroku as a place for deployment
- C9: Developing in the cloud rather than on your own laptop (or on a MathLAN workstation)
- Git - deeper understanding of workflow and such
- SQL, at least a bit
Bigger picture issues
- “I can learn stuff without a textbook or teacher providing all the information.”
- Feedback from your team and from the software is helpful. Work in systems in which you can get feedback.
- Learn a bit about new technologies quickly.
- Sometimes you have to work at a high enough level that you just trust that things underneath work without understanding them.
- Too large.
- Sam took on too much teaching responsibility.
- Wrong format.
- Switch back to the textbook.
You know the drill.
Quick Debrief: Class
- Would it work to have 321 + 322 + 322 in one semester? Need is unclear.
- Should I go back to Hartl? Probably. There’s not really enough material
to support the Rotten Potatoes stuff. The Rotten potatoes stuff needs
- Why Cucumber? It’s probably a bad idea. Let’s switch to RSpec or whatever.
- Something in between would be nice.
- Three hours straight on Tuesday/Thursday morning (bad idea). Two hour chunks would be better.
- Notify us in advance that there’s an electronic version of the SaaSbook and that the electronic version is preferred.
- Use the SaaSbook only for software design, and probably look for another textbook.
Debrief on Alumni Visits
- Useful advice: Use popular gems - Confidence that they work as intended, don’t have security flaws, and likely have good documentation and a support community.
- Useful advice: Use gems, rather than building stuff yourself.
- Useful advice: Look at how recently things have been updated (programs, documentation)
- Stable is often better than cutting edge
- Beyond coding: Your first job is not your career, you will probably move.
- Beyond CS: Grinnell remains your home
- Tools to use: RSpec or Minitest, rather than Cucumber
- They are an exciting, good, resource.
