4. Don't live with broken windows
5. Be a catalyst for change
6. Remember the big picture
7. Make quality a requirements issue
8. Invest regularly in your knowledge
9. Critically analyze what you read and hear
10. It's both what you say and how you say it

Thinking
    What
    Interest
    Sophistication
    Detail

    Motivation

• Know what you want to say
• Know your audience
• Choose your moment
• Choose a style
• Make it look good
• Involve the audience
• Be a listener
• Respond

Tackling

1. DRY - Don't Repeat Yourself
2. Make it easy to reuse
3. Eliminate effects between unrelated objects
4. There are no final decisions
5. Use tracer bullets to find the target
6. Prototype to learn
7. Program close to the problem domain
8. Estimate to avoid surprises
9. Iterate the schedule with the code

Tools

1. Keep knowledge in plain text
2. Use command shells
3. Use a single editor well
4. Always use source control management software
5. Fix the problem not the blame
6. Don't panic
7. Take the signs for what they are
8. Don't assume it - Prove it
9. Learn a text manipulation language

• Debugging steps

1. Are you seeing a symptom, or the root cause?
2. Write down the problem as in an email to a co-worker
3. If we see problems and the tests are passing, then are the tests complete?
4. Where else does this problem exist, or need to be checked?

__fix__
The QMainWindow exists in the QtWidgets directory, so add the following to the Makefile (perhaps there's a way to add this to the .pro file):
-I/opt/Qt5/5.2.0/gcc/include/QtWidgets
