Notes:

(5/12) This might be the best set of LAN projects I've seen, is also the first time I've assigned the 'simple floorplan' as a separate project and focused on the points that are often missed. Thanks for that! More HOL projects used the sample code to good advantage than usual, but given the way this semester went, I'm happy to see the samples tweaked at to get the Hands on Linux experience. Thanks for that, too!

(5/12) Final Grades are posted with eServices. There was a steady stream of email about projects and there wasn't a chance to post grades for review before they went to eServices at the deadline this noon. If there are errors or ommissions please let me know and if they affect your grade they'll go on a change of grade form.

(4/27, 5/3) End of semester: The websites for the HOL project are due Friday May 8th, will be checked in Saturday morning.

Quiz #3 was or will be at the Exam Time for your class:

An optional exam worth 40 points, covering topics from Quizzes 1 and 2, will be available after Quiz #3. If taken, it will replace the points earned on Quizzes 1 and 2. Or, Quiz 1 or Quiz 2 may be repeated and the points earned on the retake will replace the earlier score.

(4/29) Command Line Testimonial I get lots of these, along with lots of regrets from Seniors who can't get the job they want because they blew off the command line and vi exercises in my classes:

I am currently working as a Cyber Security Consultant with Deloitte in D.C. Once again I thank you for teaching us the Linux command line in class. I would have not been able to work where I am without it, as I'm working in a very heavy command line environment. Currently navigating logs, standing up boxes and automaticing communication, and building out a Cloud Security Service Provider.

(4/28) Final Topics: Quiz #3 will cover the Data Representation and Storage Topics, plus questions about the HOL project.

Video Lectures for the Storage Topic have been posted.

Please read the Security and Professional Standards topic on your own. It won't be on a quiz, but has good links to the professional standards for IT. COBIT, GIS, ACID, PCI, CIA & CIAAN, SOX, ITIL and others are good to know about for any kind of interview for IS positions, and can help keep you out of trouble after you're hired.

(4/23) A video about Part 2 of the HOL project, Outlines/Brief1, has been added to the HOL lectures. Please check it out and get any questions answered: HOL Project Lectures.

(4/23) The video lectures are up for the Data Representation topic. This is an important topic and would get lectures for two regular class meetings. They're here in 4 shorter videos: Video Lectures about Data Representation. There's also a link on the card for the Data Representation topic. Plase read the topic, watch the videos, and ask any questions about it...

(4/21) The Data Representation topic has been edited for this semester to supply details that are usually given on the board in lecture. A few videos will be up soon with the lecture including googling on terms that would usually be in a lecture. Please get a start on the Topic. The remaining few sub-topics from the Storage and Professional Standards should be up by Thursday...

(4/17 Late) Response to yet another unacceptable LAN Project: Example of an Acceptable LAN Project. If you haven't already, get me a single pdf with the diagram and the rough bill of details. This is an example of an acceptable project and I wonder why you're days late and unable to make a professional result when most of the class got all the points? I do not grade unacceptable work, I give it a zero. I expect stuff to be delivered on time and not cause me grief or hassle.

(4/17) Part #1 of the HOL project was scored from these snapshots taken Friday morning:

The Topic in Place is due next, and it's not too early to put up your outlines.

(4/16) A sample quiz has been put in your home directory as a file starting with your userid at info300.net. Please check it out, get comfortable with vi, and be ready to take Quiz #2 with vi on Tuesday. Please pay attention to the advice about not letting vi time out in INSERT mode while you're not actively typing in INSERT mode. Use :w to save your work between questions.

(4/14) Due Dates for HOL:

The main points for the website are for the page layout and content to be marked up semantically. Other specs for consistent navigation, mobile-friendly, W3C validation are also important. Find an article or two that you can outline into several subtopics for the outline that's due on the 23rd. In the website, mark up your article with <h1 and <h2 tags, <h3 tags are optional but would go a long way towards convincing some technical interviewer that you understand how to use semantic markup.

Please make sure that your VCU email account has your first and last names showing. A first name only, or a name like 'VCU', doesn't help the recipient who's got to check stuff in...

(3/26, 4/12) Due Dates for LAN Project:

(4/12) Quiz #2 is tentatively set for Tuesday the 21st. It will cover the Networking and Data Centers topics and ask questions about the LAN and HOL projects. It will be 'open notes' with internet access, taken on-line using the vi editor. A smaple quiz will be posted into your home directory at info300.net later this week. Please make sure you can keep your video running for the quiz and be ready to show your VCU Id next to your face.

(4/12) Videos have been posted for the Data Centers topic: Data Center Lecture. Data Centers and Cloud Computing will be in the future for many of our majors working in and managing IS or IT. Knowing what's important about them helps get lots of them past their interviews and into a career...

(4/9) Here are the videos for HOL Part 1: HOL Part 1

(4/7) Thursday the 9th we'll be starting the HOL-Hands On Linux project. UserIds and temporary passwords will be assigned and the project will be introduced, and first deliverable will be demo'd. Please show up working on a notebook or desktop somewhere with bandwidth so you can get your hands on linux and start working at the command line and get comfortable with vi...

Data Representation

(4/21) Computers are Binary machines but they input, store, compute, and output all kinds of data. Numbers are represented more or less directly as Binary, Decimal, and Hex Integers, Float, and Decimal. Characters are represented as ASCII, EBCDIC, and UniCode. When data moves from one platform to another, there's usually some translation or conversion involved. (Video Lectures | Study Questions)
