Quotable


Psychologist Eric Byrne lays out a series of painful relationship games in his seminal  book, “Games People Play.”  Let’s You and Him Fight is among the more famous.  A character who wants to start a fight says to one potential “dance” partner, “Are you gonna take that from him?”  Then says something similarly meddlesome to the other party.  Then sits back and admires the chaos he or she has started. You probably have a friend like this.
The technique sounds charming in that form — which Byrne points out is copied over and over in the world of fiction. But it’s also used by dictatorial regimes to suppress speech.  Want to crack down on a peaceful demonstration? Hire a few thugs to make their way into the middle and start pushing people around.  It never fails.  Someone overreacts. Then someone over-over-reacts.  Then a big brawl brakes out and “peacekeepers” seem justified in the use of tear gas. Or, hatred is stoked on both sides, creating social chaos that wears down the enemy.

They’ve won many of the early battles in this war. They started small, tricking you by changing half-gallon boxes of ice cream into 56 ounce boxes. But that was child’s play. Now, they track your every computer click and notice you often fly to Florida in winter, so they charge you more for your plane ticket. They send you important notices in letters designed to be misplaced and discarded; they send email bills in the middle of the night so you miss them and they can charge a late fee. They know which colors make you buy, they know what music makes you leave, they recognize your cellphone when you walk by their stores.

Advertising news
"Nearly all the shows on the fall schedule will attract a disproportionate number of viewers too old for the demographics that advertisers covet. The median age of the audience that tuned in to last season's highest-rated freshman drama, 'The Good Doctor,' was 60.8 years old, or nearly 12 years beyond the upper limit of ABC's target demo."

1.12 Need for DNS
Security
What is one vulnerability of DNS and how is that vulnerability attacked?
What are the implications of an attack on a DNS server (or servers) - how does this affect your life?
  • Assessment

  • Code Studio: Assessment questions are available on the Code Studio

  • Extended Learning
Due Friday by 8pm est - no late assignments will be accepted - send to murphyk2@gcsnc.com:
Dive Deeper on DNS: Check out this article. It provides a deeper look into the DNS and what one sees when communicating with the DNS from the command prompt or terminal.  Give me you impressions, your fears, your actions on what you will now do with this information. 1 well written paragraph will be enough.  Leave no doubt you read the article

1.13: HTTP and Abstraction on the Internet

Objectives

Explain how layers of protocols allow the Internet to function.
Use developer tools in a modern browser to explore the HTTP traffic associated with visiting common websites.
Identify abstractions used in the development of Internet protocols.
Describe how a protocol or layer of the internet acts as an "abstraction" for other layers.

Vocabulary

DNS - The service that translates URLs to IP addresses.
HTTP - HyperText Transfer Protocol - the protocol used for transmitting web pages over the Internet
IP Address - A number assigned to any item that is connected to the Internet.
TCP - Transmission Control Protocol - provides reliable, ordered, and error-checked delivery of a stream of packets on the internet. TCP is tightly linked with IP and usually seen as TCP/IP in writing.
URL - An easy-to-remember address for calling a web page (like www.code.org).
-----
  • Getting Started (15 mins)
The Internet Protocol Stack
-We want to think of the protocols as working in "layers".
-This picture here (also on first 2 pages of HTTP and Abstraction on the Internet - Resource) is a simplified version of what's known as the "Internet Protocol Stack." We've studied each layer separately but now you can begin to see how they work together.
  • Activity (25 mins)

  • -HTTP is an ASCII text based protocol.
  • -It's somewhat remarkable to note that many "high level" protocols, like HTTP, are just computers sending ASCII text messages back and forth. Each protocol simply defines the rules of the "conversation" between two machines.
  • -In the case of HTTP it is the protocol used for sending and receiving web pages and other web content.
  • -Today we'll look under the hood and see HTTP in action.
Show Video: "The Internet: HTML and HTTP."
The Internet: HTTP and HTML - Really pay attention to the HTTP portions
Investigate HTTP traffic on your computer
Worksheet - HTTP in Action
5 blank windows
3 dots ->More tools -> developer tools
Network tab (ALL)
Type in the name of the site as directed on the handout
Gleefully sit back and watch the action
compare
During the activity, students will:
-Access the developer tools of their browser.
-Monitor the HTTP traffic generated by visiting a variety of websites.
-Record their findings, using the resource as a guide.
  • Wrap-up (10 mins)
-What surprised you about the HTTP traffic you observed?
-What does it mean to say that high-level layers of the Internet use low-level layers “abstractly”?
-What other examples of abstraction have we seen in this course? Hint: Unit 1 is basically all about abstraction.
  • Assessment
Code Studio: Assessment questions are available on the Code Studio.
  • Extended Learning
-Research SMTP, a high-level protocol for formatting email messages.
-An excellent resource for explaining the many layers of protocols that make up the Internet: Internet Techniques and Web Formats.
HW -
Blown to Bits - pp 309-316 (The Internet Spirit)
The layers of protocols used in network communication is an example of abstraction. Can you give other examples of abstraction in everyday life?
When you browse to a web page, maybe with some animated advertisements embedded on it, describe in detail what happens behind the scenes to display that page on your browser.
Blown to Bits - pp 73 - 77
Discuss how not knowing some basics of how a software tool or computer works, and the abstractions they use, could lead to bad outcomes.

 Due Tuesday, Sept 25, 5pm - email to murphyk2@gcsnc.com
