CSP Unit 2 Stage 1 - Question #3

Shakespeare’s complete works have approximately 3.5 million characters. Which is bigger in file size: Shakespeare’s complete works stored in plain ASCII text or a 4 minute song on mp3? How much bigger?

- It depends on the MP3 quality, the rule of thumb for MP3 audio is that 1 minute of audio takes up about 1 megabyte. Therefore, it would be around 4 MB instead of 7.68 MB and the 3.5 MB of Shakespeare's work would still be a smaller file size by 0.5 MB less. A high-quality 4-minute MP3 will have about 7.68 MB, vs the 3.5 MB for Shakespeare's text. At minimal music quality, the MP3 is only slightly larger than Shakespeare, at 3.84 MB. Much higher MP3 compressions are possible, but not commonly used for music.

Flash Talk  

The internet today is a widespread information infrastructure. Its history is complex and involves many aspects - technological, organizational, and community. And its influence reaches not only to the technical fields of computer communications but throughout society as we move toward increasing use of online tools to accomplish electronic commerce, information acquisition, and community operations. Although, a couple of situations arise due to the influential upcoming.  

Internet censorship for one, is an issue facing society concluding into many positions and views. It occurs in many forms carried out by governments or by private organizations or by individuals. This may be done through physical means or software on the TCP/IP level in 4 ways: internet backbone(usually on international gateways), ISP (governmental filtering that is mandated), institutions(self-induced filtering or technical), individual computers (downloaded software filters). IP blocking, DNS Tampering, and URL Blocking use a proxy to block web-pages, domains, or IP addresses.  Keyword blocking censors information based on words in the URL or from searches by HTTP protocol manipulation. Denial of Service attacks on DNS are also used to prevent service from certain websites.  

Internet censorship has a variety of societal impacts. It may be used to protect safe environments such as libraries and workplaces from hate speech forums, sexually explicit material, and gambling sites. However, numerous suppliers and legislative branches mishandle this separating framework to confine the data that can be passed onto the general population. While this might be contended as a technique to keep up social and religious congruity, this xenophobic conduct does not excuse the carefully chose information just that the general population see. In the event that a country, for example, China, Vietnam, Iran channels what it considers fitting to keep monetary exchanges strong and forestall dissidence, then this blocked data must be sufficiently critical to be a resistance to the delicate consistency of devotees. This restriction might be found in China's Great Firewall of China, used to effectively cut associations continuously, representing a danger against free data and the prosperity of the country's kin. 

Through watchful investigation, plainly while web control shields minors and the delicate from undermining content, web oversight is a devastating force that can't be used by any individual without spreading to a bigger scale. In this way, Internet Censorship must stop at where it at present is, and be removed for truth and free space.

Reflection for WBL Course #2 in Library

  On November 14, 2016, the web academy had a WBL course to attend at the CCEC, formerly known as the library. It was unexpected but we went upstairs as a group. We came into the library and were handed a really thick packet of papers. The course was based on learning about various methods in order to find our strengths. Finding our strengths is the beginning of the pathway onto pursuing the career we want. I found this course to be educative, since you learn a little more about yourself and the things you can be good at. But to me, in my opinion, I feel like the activities we took and talked about, as well reviewed, didn't mean much. The activities were taking quick quiz's based on what we preferred, from one thing to another. I went through them in a breeze, and I felt like it confused me a little. It wasn't like I was confused on what my results meant, but on the actual results. Since I already know what I want to be in the future and what I'm skilled at, the results somewhat opposed but yet agreed with my choices. I want to be an accountant as my major and have minors in technology based careers or have a minor in real estate.
  Overall, the course gave me a different insight on my skills and likes but I had already taken similar activities in order to be sure of my career choices. I feel confident in myself in order to fullfill my dreams and stay on task with my studies. The course made me feel a little more motivated knowing I can be successful in life and have a bright future, not having to struggle financially. If I stay focused throughout my high school years as well as my college years, I will definitely be at the place I dream of now. The college I plan to attend is somewhat high quality as well, so I have to keep trying hard and putting my best effort. This course made me feel that way, to keep getting skilled in my area but as well build up on my weaknesses.
  My results were towards Enterprising, Conventional and Social. This are my strengths and I knew this even before taking this quiz's/activities.

Intro to CSS

Today in Class, we had a couple of assignments. Our very first assignment was to finish whatever we didn't finish on studio.code.org from the previous lesson. After that, we were given a worksheet by the sub based on a video about IP Addresses and DNS. The questions on the worksheet were pretty easy since the video gave away most of the answers; for some questions though, I had to look it up. After the worksheet, we went onto w3schools.com for a quick intro to what CSS was. Some of us knew already, some of us didn't or some of us had a clue of what it was. I somewhat knew what it was so it was quick for me to get the hang of it on the Exercises. The exercises were simple and straight forward, I got all of them correct. I like working with CSS, makes coding and life easier for now. I took notes on the CSS Syntax and Selectors.
