A "Simple" Change to a Web App
Imagine a basic web app (SPA, REST API, Sql database) with a new-user registration form. The form collects a first and last name of a new user. It is decided that the middle name needs to be collected on the form as well.
Rules of Thumb for Software Developers
Fetching Data
- Remember Performance issues go unnoticed during development because the data set is too small - Vlad Mihalcea
- A transaction should fetch only as much data as required by the current executing business logic - Vlad Mihalcea
Optimization
- Premature optimization is the root of all evil - Donald E. Knuth
- Measure performance before and after each attempted optimization. J Bloch
- Programs spend 90 percent of their time in 10 percent of the code.
Design
- The components of design that are most difficult to change after the fact are those specifying interactions between components and with the outside world. Cheif among these design components are APIs, wire-level protocols, and persistent data formats. Bloch
- Strive to write good programs rather than fast ones. J Block
