IT Infrastructure & Security - Winter/Spring 2018

Notes:

(4/22) HOL Part 2 is being scored from these snapshots: Morning | Afternoon.

There are also these more detailed snapshots, listed by the first digits of the V Number: Morning | Afternoon.

(4/17 Afternoon) Points & Critique are complete for all HOL Part 1 and timely LAN projects. Late project will be posted in a day or two...

(4/13, 17) The HOL Project is being was scored from these snapshots and log entries taken Friday morning: Morning | Afternoon

These snapshots were posted Tuesday for early Aces and feedback:Morning | Afternoon

(4/12) Bootstrappers and others using CSS frameworks: Learning and using Bootsstrap is valuable, helps make mobile-first, responsive sites that work the same way across devices and window sizes, and makes good-looking exhibits for your portfolio of technical stuff. Lots of our graduates start their careers with webwork, and frameworks are widely used for it.

Bootstrap CSS doesn't validate cleanly and that's OK with me. Bootstrap was an early adapter of dynamic CSS3 and HTML5 and has 'normalized' Bootstrap so it works the same for mobile-first, responsive websites. Some of the tricks for normalization don't validate at W3C CSS validator, but HTML should all be valid. Use vi for everything you can, avoid SFTP for all except moving images to the server...

(4/11) Quiz #2 will be Thursday the 19th. We'll be turboing through the remains of the Networks topic in the next two classes so please read ahead and get answers in class.

(4/3) The HOL-Hands On Linux & Tech Market Brief project is afoot. The Progress Pages are active at info300.net and classroom demos of working with the vi editor at the Linux command line start today. This project is all about working with vi at the command line so do not use any other editor to edit files and don't use GUI tools like FileZilla or WinSCP to make and navigate among your directories. Unix and Linux are the #1 Most Used OS in the world today and these exercises introduce the basic skills to work in the environment.

Find a vim/vi tutorial you like and learn to use the editor including copy/paste, search/replace, and get comfortable using vi. When making File1, File2, and File3 please edit polite, nicely formatted text with a max width of 75 characters. You can configure vi to do it, or you can set your terminal window at about 75 chars wide and do it by hand.

Check Ms Hossain's notes about the project, read the specs, get your questions answered, get to work...

First Three Topics:

Info Tech Infrastructure, in recent tradition, is in three major technologies: Computers, Networks, and Storage. The course starts with these major topics. For a few decades, we've seen these as separate boxes built by companies like IBM, Cisco, or Seagate. After 2015 or so, we've seen these technologies virtualized and hyperconverged a few ways, including an ARM64 SOC released in 2017 that does it all...
