Important Updates for All Students
enrolled in Spring Semester 2022


[LAST UPDATED: 1/19/2022]


  • MINI 1 and JIT 1 scores posted. Emails on the way. JIT 1 compiled questions also posted. MINI 1 scores are posted on Canvas and each of you should receive an email with details on your individual submission by the end of the day. Overall, this was a very good set of submissions, especially for MINI 1. Almost all were well organized and well written.. NOTE: Be sure to watch your use of "quoted" passages. Your goal is 0% in the precis and the summary. With or without "quotes" simply copying and pasting the work of others is not acceptable as it does not reflect what you have learned. Also remember, we continue to "up" our expectations, as early as MINI 2, so I hope everyone can keep up the good work. The challenge is to provide both precis and summaries that are more thorough and detailed while at the same time realizing that it is not merely a matter of how many words you write, but the words you use to convey your information.

    The overall average for A338/A538 combined was 79.39% or 11.91/15. Scores ranged from 5/15 to 15/15. It appears some of you may have run out of time and had to submit only partially completed assignments. For the future, the place for everyone to strive for improvement will be a greater level of thoroughness and detail in your precis, proper use of technical vocabulary (which we will be constantly working on together) and making sure you use only your own words in what you write and submit.

    If you have questions about your score, start by responding to the feedback email you receive. Again, MINI 1 was worth 15 points. JIT 1 was worth 3 points.

    JIT 1 compiled questions posted. If you scored 0 on JIT 2 it means either you did not submit, you missed the deadline, or you failed to submit in precise accordance with the submissions instructions. The compiled JIT 1 questions for the class are posted near the top of the Homework Assignments page. There are some excellent questions here and I would encourage you to have a look.

  • A338/A538 TEAMS have been posted along with Final Project Introductory Desription with topics: There is now a link on the Homework Page in the Final Team Project Resources section (near the top) showing all the team membership assignment. As already noted, everyone enrolled in A338/A538 is a member of either Team 1 or Team 2. You are strongly encouraged to make contact with your teammates as promptly as possible, and begin to sit as group in class on Tuesday, January 18. I will ask you to figure out what communication method (Slack, Discord, Skype, Zoom, Duo, ??) works best for your team.

    I have also posted, in the same section of the Homework Page, the introductory version of the Team Final Project that includes, at the end, all the topics we brain-stormed together in class on Friday, January 14 along with a few additional topics I have added at the end and that appear as bold text.

  • Just-In-Time (JIT) JIT Assignment 2 and MINI Assignment 2, along with MINI 1 examples, are Posted: JIT 2 and MINI 2 are both available on the Homework Assignments Page. JIT 2 is due by 10PM EDT on Sunday, Jnuary 23, 2022 to Jeff (jwhitmer@cs.indiana.edu) via plain text direct email and MINI 2 is due by 10PM SHARP on Sunday, January 23, 2022 to your Canvas "MINI 2" assignment. Both links point to the same file, just as with MINI 1 and JIT 1. Keep in mind it will be reasonable for us to expect more thorough and detailed submissions to earn full scores for MINI 2/ JIT 2 than for previous submissions. We plan to have the MINI 1 scores posted and emails to you with feedback by the end of the day Wednesday, January 19, so you will have time to benefit from that feedback before MINI 2 is due.

    I have also placed two links after the MINI 1 link on the Homework page. The first is a set of answers for just #1 on MINI 1, showing an unsatisfactory submission, a satisfactory submission, and an exemplary submission (which should be everyone's goal.) The second link is a set of "full credit" MINI 1 submissions from a single student from a previous semester. I did it this way so you can both see what we are striving for versus what is not up to our expectations, as well as focus on the writing, the detail, and the organization of these submissions within the work of one student. I hope it is useful.

  • Important Reminders for the start of Spring Semester 2022

    Indiana University asks that you keep the following in mind as classes begin:

    1. Please remember a properly fitted mask must be worn at all times while inside any Indiana University building.
    2. Please refrain from any eating or drinking while in class.

    Your cooperation helps protect everyone.

    Thank you.

  • Welcome to A338/A538: Network Technologies and System Administration.

    Important Notes for Spring Semester 2022.

    ALL of the primary A338/A538 Web pages are now available. You will have to have a valid IU NetworkID AND be officially enrolled in A338 or A538 in order to gain access to detailed course resources like Meeting Outlines, Homework Assignments, and other such resources. If you are officially enrolled in A338 or A538 as of Tuesday, January 11, 2022, you should be able to access these restricted resources WHEN they become available. For Example, the JIT 0 assignment will be available via the "Homework Assignments" page of the course website before classtime on Tuesday, August 11, 2022. Students officially in the course should be able to access it at that time. Likewise, the "Meeting 1" outline will be available before class on 1/11/22 via the "Meeting Outlines" page. The "General Course Information" and all other links are "live" and provide some additional details and should answer some of your questions.

    If you follow a link and get the "Forbidden" message, it means I have not yet unlocked that resource. HOWEVER, if you get "permission denied" or "authorization required" it means you are not officially enrolled, or not on my access list. If you believe you are officially enrolled and cannot access these resources on or after 1/11/2022, please contact me.
