12/6/19 - Ethical Data Collecting

In your response state why you believe the issue you chose is the most important consideration when it comes to ethical data collection:
     Consent is the most important consideration when it comes to ethical data collection because if everyone gave their consent, there would be no issue in the first place. In other words, the other four ethical data collection issues (Privacy and Confidentiality, Ownership and Authorship, Governance and Custodianship, and Data Sharing) wouldn't be issues if everyone was fine with their information being shared across the world.
Then give a ONE paragraph summary of the second related news resource you chose and include a link:
     https://hitconsultant.net/2019/11/14/a-delicate-balance-ai-and-data-privacy/#.Xepv6yLYrnE
     This article discusses consent in the medical field and the rules regarding patient consent. The main set of rules regarding patient consent is the NHS code of conduct, which allows medical professionals to obtain patient consent as a part of a clinical trial. The companies performing these trials are legally able to use patient's data without any ethical issues arising. Additionally, the NHS is expected to alter the code of conduct to hopefully convince more patients to share their data. By generating a greater awareness of Artificial Intelligence technology, the NHS believes they can accomplish their goal. They hope to get rid of the idea that companies are using their data to get more money, and replacing it with the idea that companies are using their data to further medical technology and hopefully save lives. By mentioning many pros and cons, the article is effective at being relatively unbiased, despite the author being heavily involved with AI.

12/6/19 - Explore Task

Yesterday I decided on my topic (PhotoMath), created a slideshow to put my information in, gathered all of my sources (including two recent) and labeled them according to the topic they corresponded with. I labeled every slide with a different section of the written portion (2a, 2b, etc.) so I can easily change the bullet points into sentences on a doc later.

Today, I will talk to Ms. Kelly about my last explore practice and what I should think about regarding the upcoming one, and then I will start writing my 2a based off the sources I found

12/4/19 - Submarine Cables

1. Is it true that sharks biting the cables is a problem?
     In the past, sharks have been attracted to the electromagnetic signals emitted by the cables, causing them to bite and damage the cables. However, this has not been as much of an issue nowadays, and it should be less of a problem in the future because Google is trying to develop a way to prevent cables from being damaged.
2. Cables can break just by wearing out - but what are some other things that cause them to break?
     Cables can break from fishing vessels unintentionally hitting them, ships dragging anchors over the cables, earthquakes can harm them, and underwater damage, although uncommon, is a possibility.3. Who uses submarine cables?
     Everyone who owns an electronic device uses the submarine cables to send data around the world or to an electronic device in the next room over. 4. How thick is a cable?
     They are usually an inch wide, or about as wide as a garden hose, however, the filaments inside it are very very thin (about the size of a strand of hair). 5. How does fiber-optic technology work with the cables?
     Light travels at incredible speeds with the light bouncing off the cable walls the entire way down the cable. The photons reflect off the pipe while the light beam goes down the core of the cable.6. What did you find most interesting about the cables?
     I found the distances they travel to be the most interesting. It's incredible how light can travel thousands of miles in a cable on the ocean floor so you can do anything on the internet. I also found it interesting that sharks and other sea creatures are attracted to the cables because I never really thought about the impact of the cables on the environment.

11/26/19 - IP Addresses and DNS

  1. What is a protocol?
    1. A protocol is a set of "rules" for transmitting data between electronic devices such as phones, computers, tablets, laptops, etc.
  2. What is an Internet Protocol (IP) address?
    1. An IP address is a list of numbers that is assigned to a specific device that is connected to the internet in order to identify and address a device.
  3. How is it organized hierarchically?
    1. The first numbers are the country/network, the next numbers are the region/network, followed by the sub-networks, and finally the specific device.
  4. How many bits are in an IPv4 address?
    1. IPv4 addresses are 32 bits long.
  5. How many IPv4 addresses does that mean there are?  
    1. That measn there are 4 billion unique addresses.
  6. What is the difference between IPv6 and IPv4.  
    1. IPv6 uses 128 bits per address instead of 32 bits per address, which allows for 340 undecillion IP addresses instead of 4 billion.
  7. Why do we need IPv6?
    1. More and more people are getting devices that need to be assigned an IP address, which means that soon, there will be more than 4 billion devices in use, and therefore they need more IP addresses to assign to new devices.
  8. What is an IP packet?
    1. An IP packet is the basic unit of information in network transmission.
  9. What is the difference between an IP address and an IP Packet?
    1. An IP packet contains data unlike an IP address.
  10. What is the purpose of the Domain Name System (DNS)
    1. The internet contains a directory of domain names, of sorts, and uses that to translate them into IP addresses. This makes it easy for people, who understand domain names more than IP addresses, and computers, who translate the domain names into a string of numbers they understand.

11/22/19 - Blown to Bits

Koan 2: I chose Koan #2 because I enjoyed reading about the "then v.s. now" of literature, pictures, email, and "perfect copies." Simply put, this truth stated that the "perfect" pictures, books, videos, etc. on the internet will only work if the internet does. For example, if the power went out and people couldn't access the internet, the "perfect copies" wouldn't have any use anymore. Additionally, if an error was made in pictures and other electronic copies, the error detection and correction mechanics are almost guaranteed to catch them. The final statement, "Once I release them, everybody has them. And if I give you my bits, I don’t have any fewer," struck me because of the original v.s. copy debate and how it has changed over the years.

Koan 3: I chose Koan #3 because it discusses the benefits and disadvantages of records being on computers v.s. on paper. While having the records on the computer is easy, the transition period from paper to computer left some records lost. For example, a doctor and a patient tried to figure out if the patient had ever had a stress test done. Recalling on vague memories, the patient remembered having one, but there was no record online. The stress test results were on paper, while the rest of his results were on the computer. The division between paper and computer is huge, and only continues to grow as the internet does. The author also points out how humans have become "lazy" in a way because if the results don't pop up immediately on a search engine, we assume it doesn't exist, which is not always true.

11/4/19 - Marconi Field Trip

 This exhibit showed how researchers use wireless communication to tag sharks, using three different methods. The three types are the PSAT Tag, the Spot Tag (the most common), and the Acoustic Tag. The computer screen below allowed visitors to explore the various methods of tagging/tracking sharks as well as view photos and videos of sharks during the process. I chose this because growing up on Cape Cod has made me curious about the marine wildlife surrounding my home. Also, it shows how wireless communication is involved in everything because of the connection between marine biology and wireless communication. This is significant in wireless communication because it helps marine biologists everyday in their jobs, it took years of development to reach this point (allowing it to be waterproof, developing how to attach it to the sharks without harming them, etc.), and it will lead to the development of higher technologies in this area.
 This was a part of the wireless communications throughout history exhibit. As seen in the corner of the photo, this particular machine is from the 1950s. I chose this because it was interesting to see exactly how it developed, especially 70 years ago. This is significant to wireless communication because it shows how it developed from what you see in the picture to what we use today (smartphones and other smart technology, to name a couple). 
 This is a simulation of the listening positions of radiomen during WWII. These people would listen for Morse code over the headsets and type it up on the "mill," where they were hand-delivered to Washington D.C. I chose this because I have always been interested in WWII, as it is such an important time in history, and because I studied Morse code for the project we completed in class. This is important in wireless communication because it marks a period in history when humans had to transfer data instead of the machine doing it.
 This is an exhibit showing every separate machine in a certain time period in history that, now, is in one device: the smartphone. I chose this exhibit because it was interesting to think about how people performed everyday tasks without a smartphone. Though I was born before the first smartphone came out, I can only remember times with it. This is significant in wireless communication because everything from phone calls to GPS to music apps are contained in one device, which was once thought impossible. To do a simple task on a smartphone that most people don't think twice about might've taken longer (in certain situations) without it.
 This exhibit is the radio transmitter used during the early 1900s in Chatham to communicate with boats across the Atlantic ocean; most notably, the Titanic. I chose this because it was interesting to hear about the radio transmitter in the movie (also shown at Marconi) and then to see it in person. I also liked how authentic it is, with many of the components being original and the flickering of the lights, for example. This is significant in wireless communication because it is connected to a major moment in U.S. history: the sinking of the Titanic. As we heard about in the movie, wireless communication was a major factor in helping people survive the sinking.
This radio receiver, named the Atlanta, was used in Marconi at the WCC throughout the 1900s. I chose this exhibit because in one of my previous photos, I discussed the radio transmitter, and I wanted to see another aspect of wireless communication. This radio receiver is important in wireless communication because it was one of the first types of wireless radio receivers, and was in use for a few decades.

10/27/19 - Coding in the Wild

I chose to read about coding in healthcare because I want to major in Kinesiology/Exercise Science in college, and later become a Physical Therapist. The writer explained how he began his career by "being an extra set of hands" working in a lab and later turned into a research engineer at the same lab. He learned beginner coding languages like "python" and "R" in order to work his way up into more advanced coding languages, and eventually begin his masters in Bioinformatics, where he used coding daily to further advance health studies. Overall, he stressed the importance of the use of coding in hospitals and labs to help patients with various illnesses across the world.
