20. Digital Analog Duplication of data without loss of quality Wear of tapes, Bleed through, Generation Loss Cheaper, more portable devices Larger, heavier, more expensive devices Distortion and Drop Out No Drop Out, Peaks can be controlled Sampling (makes a circle or wave into a square) Continuous copy (preserves circle/wave) Compressed information easy to share/transport Requires original tape and equipment
34. Shutter For video, think of the shutter as a rotating half disc placed in front of the aperture. - every pass interrupts the flow of light - every interruption marks a new frame Shutter speed = How many times does the shutter rotate per second?
35. Shutter For video, think of the shutter as a rotating half disc placed in front of the aperture. - every pass interrupts the flow of light - every interruption marks a new frame Shutter speed = How many times does the shutter rotate per second? - Video = 30 frames per second - the Disc needs to rotate twice for each frame of video, so the standard shutter speed for 30fps video is 60.
36. Controlling Light Add Light (interior / dark situation) Reduce Light (sunlight, exteriors, very bright situation) Open iris = lower F-stop Close iris = raise F-stop Increase the Gain - adds white noise (+dB) Lower Gain/Add Filter adds black noise (-dB) Reduce shutter speed Increase shutter speed
The paper focuses on an approach to scale which treats its production as observable. I focus on the meetings in an infrastructure building project called GEON. It is their everyday concern of participants: you hear of scaling, scaling up, or scaleability. My interest then are the methods for knowing the size of geon, and how participants act on its scale.

n 1827, Sir Charles Wheatstone was the first person to coin the phrase "microphone."In 1876, Emile Berliner invented the first microphone used as a telephone voice transmitter. At the U.S. Centennial Exposition, Emile Berliner had seen a Bell Company telephone demonstrated and was inspired to find ways to improve the newly invented telephone. The Bell Telephone Company was impressed with what the inventor came up with and bought Berliner's microphone patent for $50,000.

"Revolution in the Valley" writtened by Andy Hertzfeld: The Lisa team decided to optimize their display for horizontal resolution, in order to be able to display 80 columns of text in an attractive font. The vertical resolution wasn't as important, because vertical scrolling works much better for text than horizontal scrolling. The designers decided to endow Lisa with twice as much horizontal resolution as vertical, using a 720 by 360 pixel display, with pixels that were twice as high as they were wide. This was great for text oriented applications like the word processor, but it made things somewhat awkward for the more graphical applications. When Burrell redesigned the Macintosh in December 1980 to use the same microprocessor as Lisa, the Motorola 68000, it set off shock waves within Apple. Not only was Burrell's new design much simpler than Lisa, with less than half the chip count, but it also ran almost twice as fast, using an 8 megahertz clock instead of a 5 megahertz clock. Among other advantages was the fact that the Mac's 384 by 256 pixel display had the identical horizontal and vertical resolution, a feature that we called "square dots". Square dots made it easier to write graphical applications, since you didn't have to worry about the resolution disparity.
