Written Response

1. The data was originally collected by my teacher. He sent each student a link to a Google Forms survey to fill out every morning from November 9th 2016, through November 22nd 2016. There were six questions for the students to answer. One of them was, “how many hours did you sleep last night?”,  another was “how do you feel today?”.  After the survey ended, the class had access to the all the responses in the survey.
2. To clean the data that was collected, I removed the words from the questions that only required numbers. When the response exceeded 24, the possible number of hours in a day, I deleted the value. After the data had been cleaned to my satisfaction, I made a pivot table (summary table) to find the average number of hour slept and the next day feelings. To create a visualization, I used a bar graph. The computing tools used for the artifact was Google Sheets.

3. 
   
1. A pattern visible in my chart, is the lack of accurate correlation between the number of sleep and the next day feelings. In a normal circumstance, having the most hours of sleep recommended would result in a great feeling, however, in the data collected, the greatest average of numbers 6.1 and this was for those who felt good but not great. This trend is shown by comparing the average number of hours slept and the next day feelings on the bar graph.

2. This unexpected result might be due to people spending more time relaxing rather than actually sleeping. This can predict how our essentials needs are changing. Many people are going sleep deprived,  their body becomes may become accustomed to it and it prefers the less hours instead of the recommended eight hours. Also, the question were open-ended which allows the student to interpret the question differently than their other peers. Perhaps, the students were not being honest with their responses. This is evident because, the data I deleted were quite erroneous.

4. 
   
1. I am making the recommendation for the National Sleep Foundation. Instead of just studying the hours people spend sleeping,  they can conduct further research to find the correlation between the hours a person spends relaxing and their alertness and feelings the next day.

2.  The recommendation can lead to discovering the benefits of relaxing more than sleeping. Scientist mainly associate alertness to the sleep a person gets the day before but perhaps the activity done while relaxing and the pleasure from it determines an individual’s feeling the next day.

3. My recommendation is supported because the average number of hours slept by the students who felt great was only .17 greater than those who felt terrible.  In order to make a stronger recommendation I would need to make a bar graph comparing the feelings and the hours spent relaxing and possibly the activity done while relaxing in order to make a stronger recommendation.

Encoding an Experience

Detailed encoding for Play Five Repertoire

COMPONENT	TYPE	NUMBER OF BITS/RANGE	Description /Comments
Emotion	ASCII	(0-50 characters) 400 bits	The emotion of the repertoire for example, can be “happy”, or “sad”. This can be expressed in a short one or two-word description. It will take about 10 characters to describe each repertoire and each character is 8bits.
Volume	Number	7 bits (0-100dB)	Throughout the repertoire the band is performing at a range of ppp (whispering, very soft, 0dB) and at fff (extremely loud, 100dB)
Articulation	ASCII	(0-210 characters) 1680 bits	In a repertoire, there are various types of articulations including legato, staccato, accent, slur, sforzando, and phrase mark.  Each music can contain up to 6 articulations, each about 7 characters.
Tone	ASCII	(0-25 characters) 200 bits	The tone of the music can be described in a short one to two word such as “light” or “heavy”. The tone of each repertoire can be describe in a five characters. Each character takes 8bits.
Tempo	Number	8 Bits (0-200)	Depending on the music the tempo can range from grave (15), a slow speed to prestissimo (200). It is best to represent the tempo in numbers.
Time	Number	13 bits (0-8191 secs) (0-2 hours)	The time of the repertoire can be measured in seconds since the opening of the concert to the end of the concert. 2 bits provides (0-8191) seconds for a little over two hours. This is important for knowing the order of repertoire.

Reflection:

                                                   From doing this project, I realized that not every single component that goes into performing a band concert can be encoded. This is an example of abstraction-removing irrelevant detail to focus on the valuable characteristics. Not every component of performing a band concert is important. For example, the color of the seats in the auditorium is not as important as the tempo of each repertoire.  When only the important components are mentioned, the whole experience takes less bits to encode.  However, since many things will be left out, there are drawbacks. The exact experience cannot be replicated.  This means it is lossy. Also, the exact experience cannot be duplicated because the number of bits for each component is only a rough estimation, not precise and can be inaccurate.

My favicon is a bass clef with the Nigerian flag in the background.. I chose this to express myself because I was born and raised in Ibadan, Nigeria. Although I live in the United States, my culture is something that I treasure and do not want to lose.  From an earlier age, I had a strong interest in music. I love singing and playing different instruments. I currently play the clarinet and piano but I have played other instruments in the past such as the recorder and guitar. I wanted to draw just a treble clef because that is more of my vocal range and the clef of the Bb clarinet. I choose the bass clef instead because of the limited amount of pixels I could use and because I love the bass line of music. 

Flash Talk Script

Internet censorship is a controversial topic in the world. Internet censorship is the control or suppression of what can be accessed, published, or viewed on the internet.  For my flash talk, I have narrowed my focus on internet censorship in schools.

There are many strong arguments for the disadvantages and advantages of having internet censorship in schools. Disadvantages include: student’s access to educational tools are limited, deprives students from learning. There are advantages. Helps the school manage what the student can access. It protects children from inappropriate content, parent cannot always monitor their children so having censorship in school puts them at ease, it will keep students from being victims of sex trafficking and pornography.  

A different approach to internet censorship includes IP address blocking, DNS filtering and redirection, termination of TCP packet transmissions, scanning URL for target keywords, network disconnection, portal censorship and search result remover.

Internet censorship has a positive impact on society, culture, and economy. Many organizations use censorship as a defense strategy for preventing malware, and the reputation of their companies, it prevents copyright piracy, it can control illegal and criminal activities, it protects children from illegal content, strengthens national security, parents can monitor their children, and it guards against spam.

Internet censorship has a negative impact. The government can use it to keep information secret from its citizens, more power to the government, added expense to the government, can harm businesses, and above all, it violates internet privacy.

My stance is, absolute internet privacy should not be permitted and certainly not in the schools. There is the need for both freedom and censorship. There has to be a regulation although it sometimes hinders students from accomplishing school work. In this case, the student can request access from the teacher if  school appropriate.

This year, I am opportune to be among the first students taking the Advanced Placement Computer Science Principles course at my high school using code.org. Thus far, we have completed chapter one which consists of stages one through seven. Throughout chapter one, I have learned topics varying from binary, number systems, encoding and sending formatted text.

One lesson from chapter one is stage three--sending binary messages with the internet simulator. I learned how information is transmitted on the internet by binary. My favorite part of this lesson was the information I learned. My least favorite part of the lesson was the internet simulator itself.  Although my partner and I created a protocol, having a one-way messenger made it difficult to get the message.

Another lesson in this chapter was stage six--sending and encoding formatted. My favorite part of this lesson was developing a protocol with my partner to draw shapes in the simulator. The other thing I liked was the two-way system in the message. We can send simultaneously and still be able to receive each other's messages. Everything was going well until the teacher gave my partner a cube to draw. We had planned out to use coordinates but we did not account for the lines that connected the points of the cube. This poked holes in our protocol. This mirrors what happen in reality. After an engineers built an application, profession hackers try to find its faults and things that could be improved in order for it to function more smoothly.
