Study Notes

Collaboration and Crowdsourcing

  • Users can provide feedback to inform program design and development, understanding diverse perspectives.
  • Group work can suffer from communication issues if members are isolated.
  • Testing is essential, even with effective collaborators, ensuring expected outcomes.
  • Crowdsourcing gathers input from many people online, improving applications.
  • User contributions can provide real-time traffic updates (e.g., accidents, closures).

Collaboration Example

  • Scenario: Students collaborated on a presentation using Google Docs.
  • Activities: Real-time writing, feedback comments, tracking contributions.
  • Benefits: Easy collaboration across locations, improved alignment, reduced errors.

Crowdsourcing Example

  • Scenario: Waze uses crowdsourced traffic updates.
  • User contributions: Accident reporting, road closure details, speed trap warnings.
  • Benefits: Real-time map, detailed traffic information, improvements through community input.
  • Creative Commons: Using someone else's material ethically and legally requires permission, even under licenses.
  • Privacy Concerns: Unauthorized use of personal data can have legal and ethical repercussions.
  • Examples: Facial recognition technology raise concerns about user privacy, consent, and surveillance.

Bias and Inclusivity

  • Avoiding Bias: Using representative data samples to reduce bias and ensure inclusivity.
  • Addressing Bias: Recognizing representation differences across communities, incorporating diverse perspectives when designing products.
  • Inclusivity Solutions: Examples of inclusive design in video games (character choices, accessibility features) addressing inclusivity issues.

Variables and Programming Logic

  • Data Types: Numeric variables represent numbers, Booleans represent true/false, strings represent text.
  • Meaningful Variable Names: Using descriptive names for clarity and maintainability.
  • Example Problem (with variables): Calculating values, variables.

Compression

  • Lossless Compression: Preserves data, offers exact reconstruction.
  • Lossy Compression: Reduces file size but permanently discards some data.

Data Representation

  • Binary Numbers: Data represented in 0s and 1s, with each bit having a specific power of 2.
  • Overflow: Erroneous output when the range of numbers in binary form is exceeded.
  • Analog Data: Smoothly changing data.
  • Digital Data: Discrete values, measured at specific intervals.
