1.1 Assignments this weekIndexup to index

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

1.1.1 WorksheetsIndexup to index

The worksheets are available in four formats: Open Office (ODT), PDF, HTML, and Text. Only the Open Office format allows you “fill in the blanks” in the worksheet. The PDF format looks good but doesn’t allow you to type into the blanks in the worksheet. The HTML format is crude but useful for quick for viewing online.

Do NOT open the ODT files using any Microsoft products; they will mangle the format and mis-number the questions. Use the free Libre Office or Open Office programs to open these ODT documents. On campus, you can download Libre Office here.

4.3 Locked out of Course Linux Server #1Indexup to index

A student sends me email, knowing he has locked himself out of the CLS using WinSCP. He doesn’t understand why his password has stopped working. The student is not following the rules for asking good questions, which require you to tell me exactly what userid and host name you are using when you report a problem. I ask what userid and host name the student used in WinSCP. The student then tells me what his userid is. I say that I know what his userid is; he doesn’t need to tell me that. What he does need to tell me is actually what settings he used in WinSCP. Only then does the student check WinSCP and realize that he is using a blank userid:

Feb  9 21:21:13  Accepted password for XXXXXXXX from 99.241.61.183
Feb  9 22:03:27  Invalid user  from 99.241.61.183
Feb  9 22:03:37  Failed password for invalid user  from 99.241.61.183
Feb  9 22:03:45  Failed password for invalid user  from 99.241.61.183
Feb  9 22:04:09  Invalid user  from 99.241.61.183
Feb  9 22:04:21  Failed password for invalid user  from 99.241.61.183
Feb  9 22:04:29  Failed password for invalid user  from 99.241.61.183
Feb  9 22:04:49  Failed password for invalid user  from 99.241.61.183

Linux people! In Week 1 as part of using the CLS I told you How to ask good questions and report problems well. When you report a problem, don’t send me what you think you typed, send me what you really typed.

4.4 Locked out of Course Linux Server #2Indexup to index

Another student locked out at home (Rogers) by using a blank userid:

Feb  9 11:55:40 Accepted password for XXXXXXXX from 99.246.116.39
Feb 12 20:29:34 Invalid user  from 99.246.116.39
Feb 12 20:29:42 Failed password for invalid user  from 99.246.116.39
Feb 12 20:29:50 Failed password for invalid user  from 99.246.116.39
Feb 12 20:32:52 Invalid user  from 99.246.116.39
Feb 12 20:33:07 Failed password for invalid user  from 99.246.116.39
Feb 12 20:33:20 Failed password for invalid user  from 99.246.116.39
Feb 12 20:34:14 refused connect from cpebc1401e66f13-cmbc1401e66f10.cpe.net.cable.rogers.com (99.246.116.39)

Check your userid before you use WinSCP!

4.5 Locked out of Course Linux Server #3Indexup to index

Another student locked out at home (Rogers) by using first an invalid userid and then a blank userid:

Feb 22 23:49:24 Accepted password for XXXXXXXX from 99.245.232.208
Feb 23 22:40:22 Invalid user XXXXXXXX from 99.245.232.208
Feb 23 22:44:13 Invalid user  from 99.245.232.208
Feb 23 22:44:21 Failed password for invalid user  from 99.245.232.208
Feb 23 22:45:10 Failed password for invalid user  from 99.245.232.208
Feb 23 22:45:20 Invalid user  from 99.245.232.208
Feb 23 22:45:28 Failed password for invalid user  from 99.245.232.208
Feb 23 22:45:34 Failed password for invalid user  from 99.245.232.208
Feb 23 22:46:35 refused connect from cpe84948c505b11-cm84948c505b10.cpe.net.cable.rogers.com (99.245.232.208)

Check your typing, and make sure you have a userid before you use WinSCP!

4.6 Attacks on the Course Linux ServerIndexup to index

4.7 Reading text on paper to minimize distractionsIndexup to index

The case against E-readers (from Slashdot)

Michael Rosenwald writes in the WaPo that textbook makers, bookstore owners and college student surveys all say millennials still strongly prefer reading on paper for pleasure and learning. This bias surprises reading experts, given the same group’s proclivity to consume most other content digitally. “These are people who aren’t supposed to remember what it’s like to even smell books,” says Naomi S. Baron. “It’s quite astounding.” Earlier this month, Baron published Words Onscreen: The Fate of Reading in a Digital World, a book that examines university students’ preferences for print and explains the science of why dead-tree versions are often superior to digital (PDF).

Her conclusion: readers tend to skim on screens, distraction is inevitable and comprehension suffers. Researchers say readers remember the location of information simply by page and text layout — that, say, the key piece of dialogue was on that page early in the book with that one long paragraph and a smudge on the corner. Researchers think this plays a key role in comprehension — something that is more difficult on screens, primarily because the time we devote to reading online is usually spent scanning and skimming, with few places (or little time) for mental markers.

Another significant problem, especially for college students, is distraction. The lives of millennials are increasingly lived on screens. In her surveys, Baron was surprised by the results to the question of whether students were more likely to multitask in hard copy (1 percent) vs. reading on-screen (90 percent). “When a digital device has an Internet connection, it’s hard to resist the temptation to jump ship.”
