Notes on Sane Development

Sane development?

• Aim: increase efficiency, productivity, and overall happiness
• Mileage may vary depending on workplace culture, individual preference, etc
  • mediation between personal goals and workplace goals

Aspects

• Technologies and tools
• Culture
• Personal development

Notes on Git

Why git?

• you have a distributed workflow
• you need to version files even when you’re offline
• you have a central “master” repo, but you still want git’s benefits
  • speed, smaller repo size, ease of branching/tagging, etc

Workflows

• many different branching models exist; use what works
  • depends on: team size, collaboration model, release schedules and characteristics, etc

function Node(value) {
  this.bottom = null;
  this.value = value;
}

function Stack() {
  this.top = null;

Notes on the Development Life Cycle

Prioritizing

• avoid changing the list of items to work on mid-sprint
  • be firm with clients – prevent them from sneaking in new items/making changes to their requested features mid-sprint
  • item priorities may change mid-sprint, but keep in mind that changes like these are disruptive
• points or man-days: YMMV
  • whichever you choose, be consistent (this is a team decision)
  • make sure everyone agrees on what each unit of effort stands for
  • estimates are not absolute

Notes on Vim and Emacs

Why Vim?

• Vim is the descendant of vi, designed to be (mostly) backwards-compatible
  • learning vi is useful when you need to edit a file over ssh, since vi is usually installed in any UNIX/UNIX-based system by default
• Vim’s shortcuts and design, once you learn them, help you search/create/edit/etc files quicker
  • these shortcuts are also used in UNIX-based terminals, such as the man page viewer
• Vim offers flexible window management (splitting, etc) and works well with tmux, a popular terminal multiplexer
• Vim’s plugin ecosystem is thriving and full of useful tools for development in most (if not all) languages
• you can extend Vim yourself using Vimscript

Why Emacs?
