Open source

Open source

Open source is traditionally global
Out of necessity, everything is open: images, source code, tests, documentation
At your business, this is often not the case
One piece of a bigger puzzle
Wildly different priorities

Think locally

Think globally, act locally (ok, think locally too)
Information made available to all (schemas, functions, application designs)

Same team?

In theory, everyone is on the same team

Same team>?

In reality...
Groups, department, section, sub-sections, teams, etc
Politics, budgets, people skills, technical skills

Apply to your own code, your own team, your own business.

Be open to criticism
Make it available for scrutiny
Beyond code review
You code better when you don't know who is going to look at it

Broken windows

The broken window theory
Open source is one cure
Others:: extreme programming, refactoring

Getting a big picture

Can an outsider come in and understand everything?
Forget an outsider, can an insider? Can QA?
Where is the data? Where is the database?
How often is it backed up? How does the user get to it? What do they typically do?

Job security vs. open source

The job security myth
(job) Security through (code) obscurity
Be known for good documentation, not known for being mysterious

Who does it not apply to?

Widely dispersed teams.
Training.
Very large projects.
Security.
