Hot and Cold Streaks Can Influence Programming Language Design• Call to Action

• Build programming languages conducive to hot streaks• Have concrete metrics

• Result• Utilize programming aces more effectively

Metrics For Measuring Performance• Defining a “hot” or “cold” streak for a software engineer• Often performance measured by “tests passed”

• But does this constitute any sort of hot or cold rhythm?• Needs to be done in the background

• Limited interruptions

Measurable Tasks• Within the source code (the software project)

• Unit Tests Passed• Assertions Passed• Contracts Passed• Lines of Code Written that stay in final product

• Outside of the source code (the physical programmer)• Hours of sleep• Hours worked straight• Expertise with subject matter• Cups of Coffee

Existing Tools For Maintaining Hot Streaks

Problem ToolSpeed of Compilation Incremental CompilationSpeed of expressing ideas with code

Intelli-sense, code completion

Confirmation of idea (debugging)

Step Debugging, ‘goto line’

Building confidence (testing) Automated Tests

Working out of a Cold Streak• Documentation

• Force programmer to slow down• Refactoring Code

• Encourage critical thinking• Other Productive Tasks that give you a rhythm

• Can helpful tools dynamically be given to struggling programmers?

So Take Some Time to Reflect• Perhaps you’re skeptical• Have you been on a hot or cold programming streak?• What were the circumstances?• What can we do about it?
