1.2 Assignments this weekIndex

Check the due date for each assignment and put a reminder in your agenda, calendar, and digital assistant.

• Read All The Words, Do, and then Submit via Blackboard:
  • Assignment #01 HTML – Multi-tasking and Schoolwork
  • Assignment #02 HTML – Course Linux Server simple commands
  • Really do Read All The Words. You don’t get a second chance to get it right.

1.3 Lab work this weekIndex

• This week in lecture we learn about the terminal, the shell, and using pathnames, especially relative pathnames.

• Last week, your instructor showed you how to log in to the Course Linux Server and use some simple commands.

• In the labs this week, we will do a File Transfer so that you can transfer files from the CLS to your laptop computer.

• Assignment #02 HTML will have you log in to the CLS, do some simple commands with output redirection, and change your CLS password.

• Finish the above assignments and start work on the first two worksheets.
  • The worksheets will be easier once you read File System and Pathnames.

1.4 Upcoming testsIndex

Read the Test Instructions (all the words) before your midterm tests.

1. First Midterm test: 45 minutes; in lecture class noon Friday in Week 5 (Feb 12)
2. Second Midterm test: 45 minutes; in lecture class noon Friday in Week 9 (Mar 18)

Tests take place in class in your one-hour lecture hour, not in your lab period.

2.1 Student errors in submitted assignment01.txtIndex

82 of 94 students submitted the first assignment. One person was late.

One person did not Read All The Words and uploaded Rich Text instead of Plain Text (probably a Macintosh user):

{\rtf1\ansi\ansicpg1252\cocoartf1265\cocoasubrtf210

One person did not Read All The Words and wrote text in the Write Submission box.

Seven people did not Read All The Words and uploaded the wrong file name:

Bad file name: assignment01.text
Bad file name: assignment01.txt.txt
Bad file name: Assignment01.txt
Bad file name: assigment01.txt
Bad file name: Assignment 1.txt
Bad file name: assignment01.text
Bad file name: tone0019.txt

15 people did not Read All The Words and used the wrong numbering:

( I - 2a )
(1-2a)
(I -2a)
(I-2C)
(I‐2a)                       # uses non-ASCII hyphen -- did not use Notepad
----------I-2a----------
2a)
I-2a
I-2a.

20 people did not Read All The Words and used a word processor instead of Notepad, resulting in non-ASCII characters such as Microsoft “Smart Quotes” instead of Plain Text:

<93>attempt<94>
teacher<92>s
don<92>t
i{226}{128}{153}m
don{226}{128}{153}t
(I{226}{128}{144}2a)
don{146}t

2.2 Locked out of CLS because of no userid in WinSCPIndex

From the log file last night on the CLS:

Jan 21 22:54:37 Failed password for invalid user  from 99.224.106.182
Jan 21 22:55:46 Failed password for invalid user  from 99.224.106.182
Jan 21 22:57:26 Invalid user  from 99.224.106.182
Jan 21 22:57:50 Failed password for invalid user  from 99.224.106.182
Jan 21 22:58:24 Failed password for invalid user  from 99.224.106.182
Jan 21 22:59:18 refused connect from cpe00fc8de345c3-cm00fc8de345c0.cpe.net.cable.rogers.com (99.224.106.182)

I told you the most common mistake you would make would be to forget to put in your userid when connecting with WinSCP. This student above did exactly that and got his IP address locked out of the server.

When you are locked out, follow the directions in the notes to get your IP address re-enabled.
