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...
