Week 0 beginning Mon Jan 8

Preliminaries & Comments

1. Classes start Mon Jan 8
2. Microsoft Teams: We won't use Teams for online class sessions but it is helpful for one-on-one (or one-on-a-few) meetings and office hours Q&A. So visit Participation with MS Teams and be sure you can use Teams on at least one device. It may help to include the computer you intend to use for this course to help with screen sharing and trouble-shooting via Teams.
3. Alert to Mac owners: Some of my videos are Windows media which on a Mac might get a blank / black screen; if so, visit the VideoLAN MacOS Page and download & install the correct player version for your Mac. After installation, if the videos don't play (at all or correctly) when you click a link, just drag the link down onto the VLAN icon and all should be well. This works on my Mac but let me know if you run into difficulties.
4. Alert to Mac owners: If the Mac you will use for AIST 3720 has an M1 or M2 chip (e.g., see How to check if your Mac has an M1 chip) then you will emulate VMs for this course using UTM rather than virtualizing using VMware Fusion; in further documentation any reference to a Mac M1 chip applies also to M2 chips. Nothing actionable this week but be sure you are following the correct guidance for your computer later in the course.
5. Alert to Windows PC owners: Please follow guidance at How to check if your CPU has Intel VT-x or AMD-V to verify that the PC you intend to use for class can support virtualization. If virtualization is disabled on your Windows PC you might look at How to enable vt-x (look for the section entitled Turn Intel VT-x On in Your BIOS or UEFI Firmware) to resolve the issue. Contact me immediately if you can't create VM's.
6. Note that the Operating System Concepts Essentials textbook has a Student Companion Site
7. Next Mon Jan 15 is MLK Holiday; no F2F classes

Read, Study, Execute

1. Visit AIST3720 in D2L, logging in with your @augusta.edu credentials. Note: Logging into D2L for this course is how first week attendance will be checked.
2. Read the Preface and Part 1. Overview from Operating System Concepts Essentials
3. View video Course Overview from Linux Administration Bootcamp Notes: (1) I had to set the volume up from zero to 'unmute' when I first started a new video; (2) I found I could speed this presentation up to 2x and still understand it well; (3) the video playback automatically goes to the next video in the course; you are welcome to continue watching but can stop when finished with the assigned module(s)
4. Read web article What is Windows Server Notes: (1) Ignore the ads
5. TechPrac00 due Sun Jan 14  Note quick due date

Content & Presentation

1. (Video) AIST3270 Kickoff
   1. Course processes, rules & regs
   2. Always complete the requirements in the TechPrac, not just what might be demonstrated in videos or guides
   3. If you run into questions or issues completing a TechPrac, reach out to me right away. Showing errors or typing explanations into D2L or deliverables is not a good way to get help or clarification.
   4. On screen caps: Try to capture the screen, not snap a picture with your phone ... much easier to read (usually). See, e.g., Take a screenshot on your Mac or 10 ways to take a screenshot on any Windows 10 device
   5. Be sure you can Access O'Reilly online texts
   6. Visit VMware on Brightspace for guidance on establishing a VMware subscription and downloading installs for VMware Workstation (for PCs) and VMware Fusion (for Intel Macs); if you have an M1 Mac (e.g., see How to check if your Mac has an M1 chip) the UTM emulator will be used instead (e.g., see Install UTM on an M1 Mac)
   7. Visit Azure Dev Tools for Teaching and Sign In with your @augusta.edu credentials; this gets you access to free-to-students software downloads and Azure resources. Once activated you can visit https://portal.azure.com and use your @augusta.edu credentials to get back to these assets
   8. Make sure you have 100 GB empty disk space on the computer you will use to hold your virtual machines (VMs) for class; consider purchasing a USB portable hard drive (not a thumb drive) if not -- this isn't a bad idea even if you have the disk space on your computer
   9. Time permitting a quick peek at a Simple 8-bit Assembler Simulator
2. (Video) Computer hardware basics (e.g., see TechPrac00 item I) Note: The video was from AIST2330, the precursor to this course, but the principle ideas still apply.
3. (Video) Introduction to machine / assembler lang & some OS concepts (e.g., see TechPrac00 item II) | Simple 8-bit Assembler Simulator | Assembler 101 Code | Dec-Bin-Hex-ASCII table | Easy Unit Converter

1. (Video) Week 1 Overview & Comments
   1. TechPrac00 grades to be posted soon
   2. Note Quiz01 in D2L is item I for TechPrac01 due Sun Sep 3
   3. OK to use VirtualBox or other VM hypervisor than VMware but I can help better with VMware; with an M1 Mac, UTM is the only solution that I know will work with the OS's we are virtualizing
   4. Make sure you have 100 GB empty disk space on the computer you will use to hold your virtual machines (VMs) for class; consider purchasing a USB portable hard drive (not a thumb drive) if not -- this isn't a bad idea even if you have the disk space on your computer
   5. Getting your materials together:
      1. Install your hypervisor by following guidance in whichever is appropriate:
         • Install VMware Workstation on a PC
         • Install VMware Fusion on an Intel Mac
         • Install UTM on an M1 Mac
      2. Get Ubuntu Desktop 22.04 LTS install .iso from Download Ubuntu Desktop saving this somewhere where you can find it later

      3. Windows Server 2022 Datacenter* install .iso + product key from Software in Microsoft Azure Education (use your @augusta.edu credentials for authentication).

         *The same install .iso works for both Standard and Datacenter versions of Windows Server but VMware may install Datacenter regardless of what version is chosen when building the VM. Maybe get keys for both versions while you are in Azure.

         Critical alert for Windows PC users: Do not double-click this downloaded .iso and then double-click setup.exe when this virtual drive is opened. This will start an install of Windows Server over your current operating system. See guidance below for using this .iso to create Windows Server virtual machines (VMs) using VMware Workstation.

Content & Presentation

1. Week 7 Overview & Comments

1. TechPrac04.II.A Errata: Adding Users

   When I recorded the video that accompanies this exercise -- (Video) Using basic authentication for web sites in IIS -- I happened to be on a computer that had Active Directory (AD) installed and when I add a user I used Active Directory Users and Groups. Our Windows servers don't have AD so continue to add users the way we have all term (e.g., see Adding Users scrolling down to the section Windows Server without Active Directory). Sorry for any confusion; Active Directory is not required for this task.

2. TechPrac04.III.B.7 MySQL Log Errata

   1. Sorry for any confusion but in reshuffling some assignment tasks I have TP04.III about logs before TP04.V about installing MySQL in Ubuntu. Task TP04.III.B.7 asks you to look at your MySQL log which won't be there unless you complete TP04.V first. Just something that slipped past me in prepping this term's work.

   2. Recent versions of MySQL changed default logging levels, so to get MySQL log to catch the bad login use the following from a Linux terminal to get into MySQL, change the logging level, exit MySQL and then try the bad login which should show up in the log.

      sudo mysql
      set global log_error_verbosity = 3;
      exit
      mysql # should be access denied
      sudo tail /var/log/mysql/error.log -n 1 # should show in log
