Data Visualizations Unit 2 Lesson 10

What are the benefits of visualizing data? -The information you are trying to convey can be shown to your target audience easier, and in a way that is more aesthetically pleasing. Can we characterize common mistakes in visualizations to which we gave low ratings? -Yes. Most visualizations that got low ratings are either cluttered, with too much information, or don't have enough information, so that the visualization is difficult to understand Can we characterize common strengths in effective visualizations? -Yes. Most visualization that got high ratings were easy to understand, and effective in conveying a message to the audience easily. They were also aesthetically pleasing. Not all visualizations were charts; what other types are there? -There were also pie graphs, and many other various types of graphs. Information was represented differently amongst different charts. As you embark on making your own visualization, what do you want to keep in mind so that you can avo...

Reflection on Flash Talk

Net Neutrality is an important part of our experience on the internet. Net Neutrality is a protocol for the internet that limits the power of big corporations and ISPs, and keeps the internet free and open for all who use it. Thanks to Net Neutrality, ISPs are unable to intentionally block, slow down, or charge money for specific websites and online content. The term “Net Neutrality” was coined in 2003 by professor Tim Wu. He saw, along with others, that as the internet continued to expand, it was getting so big that there needed to be a set of rules that would help govern it, prevent big corporations from taking over the internet and charging lots of money for its use. This is what the original creators of the internet intended, to have a free and open system, and Net Neutrality is what helps keep the internet that way. However, despite all these innovations, there are still ever-present threats to Net Neutrality. Ajit Pai, chairman of the FCC, wants to destroy Net Neutralit...

The 2038 Problem

The Year 2038 problem is an issue for computing and data storage situations in which time values are stored or calculated as a signed 32-bit integer, and this number is interpreted as the number of seconds since 00:00:00 UTC on 1 January 1970 (the epoch). Such implementations cannot encode times after 03:14:07 UTC on 19 January 2038, a problem similar to but not entirely analogous to the Y2K problem, in which 2-digit values representing the number of years since 1900 could not encode the year 2000 or later. Most 32-bit Unix-like systems store and manipulate time in this Unix time format, so the year 2038 problem is sometimes referred to as the Unix Millennium Bug by association. In May 2006, reports surfaced of an early manifestation of the Y2038 problem in the AOL server software. The software was designed with a kludge to handle a database request that should "never" time out. Rather than specifically handling this special case, the initial design simply specified an arbitr...

Encoding an Experience Reflection Questions

Quick personal reflections on your encoding an experience: Post in your blog the following questions and your answers to the questions: Was your experience is a good choice? Why or why not? -I do not think that my experience was the best choice for a project like this, because there is not that much to break down into categories. It is a rather straight forward process that I chose, and there is not that much that I could have broken down. Did you identify the basic elements correctly? Did you miss any? -Yes, I did identify the basic elements correctly. Do you think anyone will be able to encode this data? What challenges do you think someone will have? -I think that someone will have a challenge with encoding my process when they reach the left side of my graph, as the chart is cluttered on that side with excess bits. Did you get good suggestions for the next steps from a classmate? -Yes, I did. Amir gave me good advice on how to break down my steps m...

Component Type Number of Bits/Range Description/Comments Number of Players number 2 bits (0-8 characters) The maximum number of players to one group in golf is 4, so 2 bits is enough to encode the number of players in the tee time. Time number 2 bits (0-8 characters) The time I set the tee time to be would probably be early in the morning, say from 7:15-9:45. With 3 characters, that is enough to record the time. Course ASCII 128 bits (0-16 characters) The course’s title (“The Country Club”) in this case is exactly 16 characters. Course titles are usually less, so 128 bits is enough to encode the course name. How I did it ASCII 4,000 bits (0-500 characters) How I did it would include an explanation of how I created the tee time, online or over the phone, what course I created it at, what method I used to create it, and other details. In any case, 500 characters would be sufficient to create this account. Write no more than 300 words ...
