OPENING QUESTION:

We're going to change gears a bit today, and visit aspects of Computer Science that interact with Society (Note the capital "S").

Before we do that, go to Code.Org and refresh yourself with both the black and white and color widget and be prepare to answer rapid-fire questions about pixels, resolution and color depth.

LEARNING OBJECTIVE:  

During today's class I will:

• make a coherent argument as to weather current copyright laws are helping or harming society using evidence from an article.

• explain how copyright and Creative Commons Licenses can be applied to digital works of creativity

CALENDAR:

I'm thinking Unit Test on Friday (10/4/2024)

WORDS FOR TODAY:

I

• innovation: "A new or improved idea, device, product, etc, or the development thereof
• prototype: "A proof of concept"
• CPU: Central Processing Unit
• Binary: 0's & 1's - Base₂
• Hexadecimal Base₁₆ - 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F
• Byte: one binary 'word'
• Bit: one binary 'letter' - either a 0 or 1
• Abstraction: "The difference between the user layer and the software/hardware layer"
• compression -​ to decrease the number of bits used to represent a piece of information

heuristic - a problem solving approach (algorithm) to find a satisfactory solution where finding an optimal or exact solution is impractical or impossible.

lossless compression - a data compression algorithm that allows the original data to be perfectly reconstructed from the compressed data.

lossy compression - a data compression algorithm that sacrifices some amount of the original data to decrease file size

image - A type of data used for graphics or pictures.

metadata - is data that describes other data. For example, a digital image may include metadata that describe the size of the image, number of colors, or resolution.

pixel - short for "picture element", the fundamental unit of a digital image, typically a tiny square or dot that contains a single point of color of a larger image.

Image - A type of data used for graphics or pictures.

metadata - is data that describes other data. For example, a digital image may include metadata that describe the size of the image, number of colors, or resolution

buffering - The process of storing streaming bytes in a reservoir in preparation for playing by an electronic device.

bandwidth - The rate at which data is transmitted across the interweb measure in BITS/second NOT bytes/second.

streaming - the process of sending bits data directly to consumers as a stream of bits and not by file

intellectual property - ? (Please research)

WORK O' THE DAY: 

Today's lesson is taken from Code.Org Digital Information #11

Let us take a gander at THIS (which is to say please read for content) I have written copies as well.

This article brings up issues around copyright. Based on what you’ve read and your own experiences, what questions do you have about copyright?

Your task:

Be prepared to make an argument that addresses the following based on that article:

Are our current copyright policies helping society or hurting society?

The following videos may prove illustrative:

•  Video #1: Copyright Overview (2 minutes)
•  Video #2: Copyright in Practice (4 minutes)
•  Video #3: Creative Commons Copyright (3 minutes)

 

Answering/addressing the following questions may assist you in formalizing/finalizing your thoughts:

• What was digitized?
• What was the goal or purpose of digitizing this thing?
• Is someone benefiting from this situation? If so, who?
• Is someone being harmed in this situation? If so, who?
• Are these impacts intended or unintended? How do you know?

 

Now please re-read that article. Code.org recommends that you add annotations similar to these:

• Add a + next to sentences that show benefit
• Add a - next to sentences that show harm
• Add a face next to sentences that show impact

If time permits, please find one (just one please) source that clearly supports your claim.
