CURRENT SUMMER 2024 COMPOSITE SCHEDULE This is a very, very, very tentative, version of the SSII 2024 schedule, combining regular and potential "second" or "lab" meetings, JIT/MINI deadlines, and Individual and Team HOMEWORK deadlines at this point. Other events may be added as we progress. Keep in mind this schedule could change at any time. Such changes will first be announced clearly in class. [LAST REVISED: Monday, July 15, 2024]

  • CAT 6 scores, preferred answers, and audio discussion posted. CAT 6 scores are posted on Canvas and the solution is on the Homework Page. There is also an audio discussion in the Media Gallery. You need to scroll all the way to the bottom of the Gallery to find it. Some of you showed improvement over the first CAT in the quiz format and some fell off a bit. This shows that this went about average for the class, even though it is still the case that a score below 11/16 suggests you are not retaining many of the truly fundamental concepts in the course.

  • OFFICIAL TEAM Homework 4 EDITABLE SELF and TEAMMATE ASSESSMENT FORM posted. This is the OFFICIAL version and it is a Microsoft Word *.docx file that you will need to make multiple copies of. It is in the "Homework" section, immediately after the link to TEAM Homework 4 itself (at the bottom of the page). You will find EXTENSIVE, additional, detailed instructions directly below that link on the Homework Page. BE SURE you are very clear about all these guidelines. Failure to follow any of them could result in an assessment score of 0 and the resulting consequences for your final grade. We will discuss this again today in the New Introduction to Meeting 20, 7/17/24.

    You will prepare a separate file for YOURSELF and EACH and EVERY TEAMMATE. These files will be due to your Canvas "TEAM-based Homework Assignment 4 Self and Teammate Assessments" assignment in the "Individual and TEAM-based Homework Assignments" group BETWEEN 12:00PM (noon) on Saturday, July 20, 2024 and 11:59:00.00PM (SHARP) on Saturday, July 20, 2024. EARLY and LATE submissions will not be accepted as Canvas will not permit submission outside this time "window." BE SURE to properly name each file you submit AND submit all these files to your Canvas "TEAM Homework 4 Self and Teammate Assessments" assignment that is in the "Individual and TEAM-based Homework Assignments" group. Again, I am explicitly requiring a separate, properly named, file submission for each teammate, including yourself. Please "download" and look over this file at your earliest convenience and notify me as soon as possible if you have questions or concerns. ALSO NOTE: To avoid confusion, the link to the previously posted SAMPLE file in PDF format has been removed.

  • CAT 7 coming Thursday (7/18/24). CAT 7 will be coming tomorrow, Thursday. Please note these important details that are the same as for all previous CATs and will be used for all future CAT exercises unless stated otherwise.

    First, this is normally a timed, closed resource exercise in class lasting no more than 15 minutes. I would normally be giving you the full 75-minute class time to complete it. However, given the varied schedules people have, I will be given you a 12-hour time slot to complete it. This CAT is a "closed resource" exercise, and as for all CATs, I am counting on you to accept "the honor system" and use no external resources.

    The process in more detail is as follows: CAT 7 file, named CAT7_SS24.docx will be available beginning at 9:00am EDT on Thursday, July 18, 2024 in the "In-Class CAT Solutions" section of the Homework Assignments page. The file will remain available until 3:00pm EDT on Thursday, July 18. The CAT 6 assignment on CANVAS will become available at 9:00am EDT on Thursday, July 18 and it will lock promptly at 9:00pm EDT on 7/18/24. Only modified versions of the CAT 7 MS Word file submitted to this assignment during this time will be eligible for credit. Again, now and for the future, I will expect you to treat all CAT exercises as closed resource work. While we will be using the "honor system," if I find reason to believe that you have decided not to cooperate, I reserve the right to assign a score of zero (0).

  • Make your project SMART, and Be A Lead files posted. The Make your project SMART and Be A Lead documents we shared and worked on together via Zoom on Monday, 7/15/24, are now available in the "Final Team Project Resources" section of the Homework Assignments page since they are both relevant to the Team Organizational Report component of the Final Project.

  • JIT 7 and MINI 7 are Posted: JIT 7 and MINI 7 are both available on the Homework Assignments Page. JIT 7 is due by 10PM on Thurday, July 18, 2024 to Jeff (jwhitmer@indiana.edu) via plain text direct email and MINI 7 is due by 10PM SHARP on Thursday, July 18, 2024 to your Canvas "MINI 7" assignment in the "MINIs and JITs" group. Both links point to the same file. As previously announced, this will be the final MINI/JIT for this semester. Please note this due date is modified from the composite schedule. I have posted this a bit further in advance as seemed appropriate to give you maximum flexibility in working this into your busy schedule for this course.

  • TEAM-BASED HOMEWORK ASSIGNMENT 4 is now available via the Homework page. It is due to EVERY TEAM MEMBER'S Canvas "TEAM-based Homework Assignment 4" assignment in the "Individual and TEAM-based Homework Assignments" group on Friday, July 19, 2024 BY 11:59:00.00PM [SHARP]. The Self and Teammate Assessments will be due BETWEEN 12:00pm (noon) on Saturday, July 20 and 11:59:00.00pm [SHARP] on Saturday, July 20, 2024. BE SURE to properly name the TEAM Homework 4 file you submit and follow all the other guidelines provided in the TEAM Homework Assignment 4 description. You are strongly encouraged to read over it at your earliest convenience at notify me as soon as possible if you have questions or concerns. Every member must submit exactly the same, word-identical, file and the TEAM Homework Assignment 4 submission is expected to be a substantial improvement in depth and detail over any Individual Homework Assignment 3 submission. You are very strongly encouraged to begin contacting your teammates immediately to setup a schedule for working on TEAM Homework Assignment 4. I will publish a sample Assessment Form and offer an extended discussion of the process next week. We plan to have your HW3 papers ready to return to you Sunday (tomorrow), 7/14/24, as previously announced.

  • FINAL Version of Final Project Description posted. The "FINAL Version" of the Final Project description is now available in the "Final Team Project Resources" Section at the top of the Homework Page of the website. Because it includes all the things that were in the "Introduction" version, I have removed that link to avoid confusion. This is as early as I have posted this, so we will see if it makes a difference. Notice there are several deadlines for various components. While some of those may not make any sense now, they will before you are required to complete them. Read this carefully, when you have the time, and let me know if you find any typos or other things you believe to be "errors." We will discuss topics directly related to one of these intermediate submissions in our Monday Zoom 7 meeting on 7/15/24, and other topics in greater detail in later meetings.

  • NOTE in response to a question I often get regarding Individual Homework Assignment 3: I have received some version of the following question several times in the past regarding Individual Homework 3 and I wanted to share my basic answer with everyone whether it has been asked yet or not.

    Question: "I was wondering if Homework 3 is to be seen as a continuation of Homework 1 and/or 2. By this, I mean should we assume that we have already introduced the first two layers of the OSI model and that our reader is familiar with network terminology such as MAC addresses and frames. Or do the "underlying concepts" mentioned in HW3 mean topics such as these should be introduced again as if explained to a new client unfamiliar with any aspect of a network?".

    Answer: The answer is both "yes" and "no." NO, you do not have to repeat the entire contents of Individual Homework 1/TEAM Homework 2. Since the "Network Layer" is independently operable from the "Physical Layer" and the "Data-link Layer," you should be able to discuss MOST issues on their own. YES, you need to discuss and explain anything from the "Physical Layer" or the "Data-link Layer" that your explanations or discussions of the "Network Layer" rely on. If you need to use "MAC addresses" to explain something in Individual Homework 3, then you need to explain MAC addresses with sufficient clarity and detail that their relevance or importance can be clearly understood by your reader without any prior knowledge or experience. Also keep in mind my advice that "you do not want to avoid a crucial topic or concept because you don't want to explain it in detail."

    I hope this helps as you work on HW3.

  • Luddy Hall, Lindley Hall, and AFA images posted. As promised, there is a link after the Meeting 11 outline on the Meeting Outlines page to a set of images from Luddy Hall, Lindley Hall, and the United Stated Air Force Academy, showing different deployments and different generations of the things we looked at on our first tour today (Monday).

    The Zoom meeting from 7/1/24 is now available in the Media Gallery as well.

    The Individual Homework Assignment 1 Canvas assignment is also available.

  • Notes on Individual Homework Assignment 1. I wanted to share some quick notes based on some very relevant general questions I have received.

    1. All course materials, both outlines and recorded sessions, can be used without citation, unless citing them makes you more comfortable.
    2. REMEMBER your "Sources" page at the end and how to properly give credit for using any of those sources in the body of your paper.
    3. No appendices please. All relevant content should be incorporated into the body of the document. The submitted file should be the "body" of your paper with the last page being your "Sources" as previously mentioned.
    4. Be careful with vocabulary. Remember to avoid the "p" word, the "h" word and other ambiguous terms or phrases and use the precise unambiguous vocabulary as used in the course materials.

    I hope this information is both timely and useful.

  • IEEE article, ACM article, and "sample" outline and recording of Zoom WTS Workshop on 6/26/24 posted There is now a link on the Homework Page right after the link to the JIT Questions to the IEEE journal article about wireless on airplanes I mentioned on Friday. Keep in mind this is a referred article in a professional journal, so the authors have assumed a good deal of background knowledge of their target group of professional readers. You cannot make that assumption for the "lay reader" your Homework Assignment 1 paper is intended for. You could already have enough knowledge to make sense of some of this material, but by the middle or end of next week, you should be even better prepared to read and understand substantial parts of it. Notice how the authors actually provide an outline of their journal article on the 5th page. Also notice the "Introduction" to this paper is nearly 4 pages long. Keep in mind, this is an example to let you gain experience on what a professional, referred journal article presents to its readers and how it is organized. To further reinforce these strategies, I have linked a second article from the Communications of the ACM on High Performance Computing. While this is somewhat less technical (which is why I'm sharing it), you could recognize more or all of the strategies that we discussed in our workshop.

    Just remember, you have different goals for your first paper, but you can gain a good deal by looking at both articles and seeing how things are organized at the level of the article as a whole, at the level of the sections, at the level of the sub-sections, and even at the level of the paragraphs. I have also published the "sample" outline I displayed and briefly discussed at the end of today's workshop.

    The recording of today's Zoom meeting is in the Media Gallery.

    I hope you find them useful.
