3. Topics • Why? • Software Architecture • Software Development • Testing • Deployment • Tools
4. Why? • Maintainability • Dependability • Efficiency • Scalability • Usability
5. Why? “How does a project get to be a year late?... One day at a time. ” -- Fred Brooks Brooks Law: "Adding manpower to a late software project makes it later!“ “No matter what the problem is, it's always a people problem.” --Gerald M. Weinberg
7. Design Patterns • Observer Pattern • Strategy Pattern • Adapter Pattern • Builder Pattern • Singleton Pattern • Factory Pattern • Decorator Pattern
8. Architectures • Layered (n-tier) architecture • Event-driven architecture • Microkernel architecture • Microservices architecture • Command and Query Responsibility Segregation • Event Sourcing
9. Inversion of Control & Dependency Injection • Clarity • Modularity • Testability • Different Implementations
10. Cohesion • Functional • Sequential • Communicational • Temporal • Logical • Coincidental
11. Coupling • Content • Common (global) • External • Control • Stamp • Data • Uncoupled
12. Software Development “ If debugging is the process of removing software bugs, then programming must be the process of putting them in. ” - Edsger Dijkstra
13. Source Control • Version Control System - (SVN/TFS/GIT) • Branching / Merging Standards • Feature Flags • Commit Message Standards • Check-in Policy • Continuous Integration
14. Branching Strategies Branch per Release Branch per Component
15. Coding
16. Coding Standards • Spaces vs Tabs • EditorConfig • Naming Conventions • New Lines / Braces / Commas • Indenting • Comments • Magic Numbers
17. Code Reviews Does the code build? Does it run without errors? Does it follow coding standards? Does it follow naming standards?
18. Testing • Frameworks • Mocks and Fakes • Unit Testing • Integration Testing • Regression Testing • Automated UI Testing • Integration with Source Control
19. Continuous Integration • Automated Builds • Parameterized builds • Automated Deploys • Repeatable deployments
20. Monitoring • Application Insights • Splunk • New Relic • Retrace
21. Tools • Visual Studio / Eclipse / IdeaJ / Sublime • Resharper • Linqpad / Notepad • Command Line – NodeJs / Grunt / Gulp • Browsers – Modern.IE (Microsoft VMs) • Developer Tools / Page Speed
22. Continuing Education • Blogs • RSS Feeds • Meetups • Books • Articles • Training Sessions • Code Camps • Coding at home
