IT Infrastructure & Security - Fall & Winter 2018

Notes:

(12/7) In response to a couple of emails Friday: The Deliverables for the HOL project and detailed Specs for HOL Part #3 are near the top of the Tech Market Brief & Hands On Linux page. It is expected that students read the entire page about the HOL project and will direct their questions to it. It is expected that students will work at the command line with the vi editor to author their website at info300.net using commands like mkdir web, cd web, and vi index.html.

(12/7) HOL Part #2 will be scored from these snapshots taken Friday afternoon:

There are lots of good-looking outlines here! Make sure to reflect your outline with the h tags on your web page with the brief. A portfolio that demonstrates good semantic markup and mobile friendly, responsive web work are valuable brand skills for a few career paths. If you can explain how semantic markup is almost 100% of SEO and accessibility, that can get you past the first interview...

Expect points to be updated Saturday afternoon with Part #2 and resubmitted LAN projects.

(12/6) Points are posted with Quiz #2 and HOL Part #1. Quiz #2 got a 'Joe Brain curve' of two points...

(12/6) Obscure link: Make sure to visit the link under the topic Seven Functions of Modern Operating Systems. It'll get demo'd in class on Thursday, will be worth a few points on Quiz #3.

(12/5) The essence of the Tech Market Brief and web work is to do enough research on some aspect of the technical marketplace, outline a brief document about the tech and its market, and use the command line and vi to author the document in html5 marked up semantically to reflect the outline in Outlines/Brief1. Take care to use semantic elements appropriately and avoid creating classes where a semantic element exists for the purpose. The printed copy of the tech brief is of little consequence, with the highlighted original references about the tech marketplace weighed heavily.

(11/29, 12/4) Please note that questions about the HOL project, Linux, HTML5, CSS3 will be on Quiz #3 along with earlier announced End of Term Topics: Platforms & Scalability; Range of Platforms from Embedded thru Super; CPUs & Modern CPU Architectures RISC vs. CISC; and Operating Systems. We lost three days of classes to weather and lame instructor, are leaving a few topics uncovered and recommended as good reading about topics important for managing IT Infrastructure.

(11/30) HOL Part #1 was scored from these snapshots taken Friday morning:

(11/27) Due dates for the HOL project have been announced in class and in Silma's emails, are freshly posted here. The parts are described at the bottom of your class' page at info300.net. Here are the due dates:

(11/14) As you research your topic for the tech brief keep in mind the requirement for printed copies of the pages with the facts used in the brief highlighted. These count more than the prose you weave from them.

You don't need a lot of references, this is a brief pitched at mobile devices. Good references will highlight the market facts: size of the market in dollars and/or units in the field, the major competitors in the market and their share.

(10/9) End of Term Exam: The exam period will be used for Quiz #3 and retakes of Quiz #1 or Quiz #2 or if a students want to repeat both earlier quizzes an optional exam covering material for both Quizzes #1 and #2 will be provided. The grade from the repeat will be posted, whether it's higher or lower than the earlier. Exams must be taken at the scheduled times, no exceptions.
