Reflection from Day 2 Protocol (Homework- 9/28/17)

  1. Blown to Bits (www.bitsbook.com), Chapter 3 Ghosts in the Machine, pp. 73-80 (What You See Is Not What the Computer Knows), then answer the following questions:
    1. Give an example of your own when just knowing what a computer did wasn’t sufficient - you really needed to know how and why it was doing what it was doing as well.
    2. Talk about file metadata and how it “fingerprints” a file. Include a discussion of file metadata benefits and challenges.

Reflection from Day 2 Protocol:
  1. An example of a computer’s work is not sufficient enough is when a computer cover parts of text that the user chooses to be hidden in front of other viewers. Even though it can hide the words, the document can be run through and bring up an exact copy with the words no longer covered.
  2. Metadata is a set of data that gives information about another type of data which can “fingerprint” a file. Metadata can support or refute a claim in any situation. The benefits of metadata is that it can back up another one’s story if their metadata checks everything out. However, the main challenge with metadata is that it can be forged to make it look like the information is correct. Many people need to be wary when the metadata looks suspicious. With metadata altered, this is considered as false evidence.

Reflections from Blown to Bits Ch. 3 (Homework- 9/28/17)

Read Blown to Bits (www.bitsbook.com), Chapter 3 , Ghosts in the Machine, pp. 80-88 (Representation, Reality, and Illusion), then answer the following questions: You can find this under forms and docs/Blown to Bits How does highlighting in a PDF doc work? What are the computational ideas utilized? Continue the exploration of HTML by determining how you would complete today’s activity in HTML. Further compare your own protocol with HTML. Reflections from Blown to Bits Chapter 3: Highlighting in a PDF docs works by using a Highlight tool that will send bits over to the letters and alter the binary. The binary is changed so that when the bits processes through, the letters will be the same but highlighted in a color instead. Between my own protocol and today’s activity, they look pretty similar since they are in the same HTML format. My own protocol was a little less precise about fully doing it in HTML due to being new at the protocol.

Blown to Bits Appendix/Ch.3 Reflection (Homework- 10/11/17)

Day 3: Packets and redundancy Homework due Wednesday, Oct 11: Blown to Bits (www.bitsbook.com), Appendix - The Internet as System and Spirit, pp. 301-309, “The Internet as a Communication System,” then answer the following question: It is interesting to think about the foresight (or luck?) that caused initial Internet designers to choose a packet-switched network as the basis for the Internet. What do you think, foresight or luck? Blown to Bits (www.bitsbook.com), Chapter 3 - Ghosts in the Machine, pp. 91-92, “Data Formats as Public Property,” then answer the following question: What do you think the Internet would be like today if different companies’ network protocols were still competing for adoption for the Internet, instead of TCP being the de facto standard? Blown to Bits Ch.3 Reflection- (by Josh Lim) I believe it is foresight because they were not fully aware on their issues at the time. The designers from the experiments would have trouble understan...
