• Thanks for all of the kind feedback.
• Thanks for the feedback from Skepticality.
• Errata…Same Birthday, Three cards in three cuts
• Passwords
  • Promise you won't write it down
  • Promise you will maintain anti-virus software
  • Change passwords every 60 days
• The Law and Jury trails…Applied science?
  • What is "Beyond a reasonable doubt"
  • The probability that the evidence is accurate
    • Eye witness testimony
      • Unknown person
      • Known person
    • DNA evidence
    • Video evidence
    • Photographic evidence
    • Expert testimony
  • Study shows that "Beyond a reasonable doubt" is between 70% and 74% probable.
  • "Probable Cause" is 30% in some states, 40% and 51% in others.
  • "Preponderance of the evidence"…50% in civil trials.
  • Would you rather release a few criminals rather than lock up one innocent person.
  • I hold the government to a higher standard than criminals
• Backing up your work
  • Hardware failure vs. a house fire or theft
  • Archive vs Quick recovery
  • Carbonite

    • Quality vs. Value
    • Eyes vs. Numbers
  • Are the Eyes vs. Numbers = Audio quality hear vs. specifications. Tubes vs. Transistors
  • Audio
    • Comparing Apples to Oranges
    • Tubes are high impedance voltage operated devices
    • Transistors are low impedance current operated devices
    • The circuits that are used are different
    • Even and Odd harmonics are handled differently when either is driven into overload.
    • It is possible to model and emulate tubes using DSP chips and the right amplifiers.
  • Digital Cameras
    • DxO mark
      • Color Depth
      • Dynamic Range
      • Low-Light ISO
    • Some DSLR's score better than the medium format digital backs.
    • DxO does not consider megapixels
    • DxO does not make the measurements from large prints
    • RAW data is not equal
      • Medium format cameras have no anti-aliasing filters
      • DSLR's do have anti-aliasing filters
      • Medium format cameras output true RAW data
      • DSLR's process the data to reduce noise.
