(5/15) F I N A L Grades are posted as they will be submitted to eService before the noon deadline.

I apologize for late posting, have needed to ration close work more than usual while my eyes heal. There was a huge heap of re-takes and re-submits that I'd underestimated. The good news about it is that almost all the re-takes were Aces and some of the re-submits were, too, resulted in a letter-grade or two improvement at the last minute.

(5/4) Several students have asked about the extra credit for putting up your info300.net site on your own domain and virtual (or real) server. Get a domain, set up a linux server, firewall it, and host your info300 web pages there. Don't just put up a page at some hosting site. It should be a virtual server, like Digital Ocean or RackSpace, where you are root, own the domain, and are working at the linux command line. That's worth 5 bonus points. Getting an ssl certificate and making it able to get mail to my inbox at @vcu.edu with no warnings is worth another 5 points.

I did it in class, followed the steps in the Networking topic, a ways down the page, Setup and Secure a Centos 7 LAMP Stack. There are lots of on-line resources for setting up a virtual server, and it's a good start into a career in network management and security.

You're already working OK at the command line, this would give you something to do with it. It might be a little late to set to it, but I can wait until next weekend to post grades, is a skill I like to see, so the deadline is Friday evening.

Let me know ahead of time if you're working at this...

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...
