Lab 1: A Teaching Moment When you activate your web storage,
you might not see the disk usage listed right away
Why?
2012-03-28 Katherine Deibel, Fluency in Information Technology 8
Usage Data Missing—Why? Consider a wastebasket
We hire a person to check on it and empty it when it is full
How often do we have thatperson check its status?
2012-03-28 Katherine Deibel, Fluency in Information Technology 9
Usage Data Missing—Why? Option 1:
The employee stands by the basket constantly watching it
Option 2:The employee periodicallychecks the basket
2012-03-28 Katherine Deibel, Fluency in Information Technology 10
How often should they check? When should they check?
Storage Data Missing—Why? How many wastebaskets are there?
2012-03-28 Katherine Deibel, Fluency in Information Technology 11
Storage Data Missing—Why? UW hosts 1000s of web accounts
Each account’s usage changes infrequently
Monitoring the usage constantly would be a waste of resources

This is an example of what it means to be operationally attuned.
Operationally Attuned Think about how devices operate Observe what they tell us—feedback
Progress bars, spinning cursors, etc.
So, if you think you’re waiting for the computer but there is no feedback, it’s waiting for youOne of the most effective habits new users can adopt is to be operationally
attuned.2012-03-28 Katherine Deibel, Fluency in Information Technology 13
Icons Icons tell us a lot about software
functionality What do you think click on these
icons would do?

Paying Attention is Not Enough
Things can go wrong You may need to seek out help To do so requires knowing the right
terminology
2012-03-28 Katherine Deibel, Fluency in Information Technology 15
Le Mot Juste
Learning le mot juste, the right word for something, aids us in two ways: Helps learning ... our brains anchor
concepts to words & phrases Helps us get help ... asking “tech support”
for help requires us to describe the problem precisely
mot juste/MO zoost/ (Fr.) most appropriate word, expression

Back in the days of CRTs I’ve had a few CRT monitors go bad
One started only showing red One started only showing yellow
What do you think happened? Turn to your neighbors and hypothesize
some explanations?

Back in the days of CRTs I’ve had a few CRT monitors go bad
One started only showing red One started only showing yellow
What happened: The green/blue components died The blue component died

Colors We learned this as kids
Primary colors: Red Yellow Blue Secondary colors: Orange Purple Green
That’s for mixing pigments, not light Primary colors: Red Green Blue Secondary colors: Cyan Magenta Yellow

Mixing Light
2012-03-28 Katherine Deibel, Fluency in Information Technology 20
Cyan, Magenta, and Yellow? Sound familiar? Think printing. Color printers are CMYK printers They use four types of ink
Cyan Magenta Yellow blacK (actually Key)
2012-03-28 Katherine Deibel, Fluency in Information Technology 21
CMYK Printing Technically, CMYK printing is
mixing pigments, not light Cyan + Magenta = Blue Magenta + Yellow = Red Cyan + Yellow = Green C + M + Y = Black(ish)

Definitions Where can you find IT definitions?
Glossary in the back of the book Google query: define <new term> Online flash cards Wikipedia

Software/Hardware Hardware refers to physical devices Software refers to programs The main difference is:
Hardware cannot be changed Software can be modified
The same hardware (computer) runs different software (applications)
2012-03-28 Katherine Deibel, Fluency in Information Technology 24
Software/Hardware Separating the two is tricky A mouse is actually both
Hardware: the mouse itself Software: the mouse drivers
2012-03-28 Katherine Deibel, Fluency in Information Technology 25
It’s not just components Hardware & software make up a computer How the computer performs also needs to
be described Memory Speed Storage space
And you need to compare different performance levels!
2012-03-28 Katherine Deibel, Fluency in Information Technology 26
Speed of Change: Mile Runs How fast to run a mile?
First four minute mile was in 1954:Roger Bannister (3:59.40)
Current record was set in 1999:Hakim El Guerrouj (3:43.13)
Their speeds: Bannister’s rate = 15.04 mph El Guerrouj’s rate = 16.27 mph
45 years to get 7% faster!
Still holds the record
today!
2012-03-28 Katherine Deibel, Fluency in Information Technology 27
A Speed Comparison How fast can you run a mile?
Healthy people in their twenties run a mile in 7:30 (≈8 mph)
El Guerrouj is twice as fast as us He is about a factor-of-2 faster than
normal people
A factor-of-2 is a good rule for human strength
2012-03-28 Katherine Deibel, Fluency in Information Technology 28
One More Factor How fast do computers run?
Univac I ran 100,000 adds/sec in 1954 ASCI Red ran 2.1×1011 adds in 1999▪ A factor-of-21 Million improvement▪ This was a teraflop machine. We have since
built petaflop machines (1000x faster)
Can we comprehend such speeds or factors of improvement?
2012-03-28 Katherine Deibel, Fluency in Information Technology 29
Factors Precisely A factor of improvement is different than a
percent improvement … factor = new_rate/old_rate percent = 100 x (new_rate-old_rate)/old_rate
Expressing an improvement by its factor is easier, especially for large changes El Guerrouj’s 7% improvement over Bannister is
a 1.07 factor of improvement
Indy 500: 1911 Harroun 74.59 mph2002 Castroneves 166.5 mph
2012-03-28 Katherine Deibel, Fluency in Information Technology 30
Analytical Approach One reason to notice the factors of
improvement is to recognize scale The time for the mile run has improved Maximum adds per second has improved
But the difference in scale is dramatic A factor-of-1.07 for the mile run A factor-of-21,000,000 for additions
Getting information is easy with IT, but we need analysis to understand its significance.
2012-03-28 Katherine Deibel, Fluency in Information Technology 31
Summary of Chapter 1 Fluency involves
Knowing the correct vocabulary and concepts Paying attention to what the computer does Being able to make comparisons

GoPost Discussions Ten weekly discussions Goal is to engage in conversations
about IT and fluency Bring in our "barnyard" of diverse
viewpoints and backgrounds Talk in greater detail about what we
might not have time for in lecture/labs
2012-03-28
Discussion Topics Topics of discussions can include anything
we have been studying Asking questions about the material Interesting applications Your own thoughts
I will add additional topics in each week Example: Digital natives and immigrants
You are invited to suggest/post other topics
2012-03-28 Katherine Deibel, Fluency in Information Technology 35
GoPost Grading Your contributions to the weekly
discussion is graded on a 0-12 scale 0 pts: No posts 1 pts: Minimal contributions
(+1, this, I agree, etc.) Up to 6pts: Contributes a decent
post but mostly repeats previous posters and does not add to the conversation
2012-03-28 Katherine Deibel, Fluency in Information Technology 36
GoPost Grading Your contributions to the weekly
discussion is graded on a 0-12 scale 7 pts: Post contributes to discussion:
says something somewhat novel or replies to previous comments
8 pts: Post contributes a link or question but does not provide context
10 pts: Significant contributions: asking questions with stated reason; posting links and discussing them; etc.
2012-03-28 Katherine Deibel, Fluency in Information Technology 37
GoPost Grading Your contributions to the weekly
discussion is graded on a 0-12 scale 12 pts: Student makes exceptionally
strong contributions to the conversation(s)
Note that serious grammatical errors posting incorrect information, or unclear writing will lose points
2012-03-28 Katherine Deibel, Fluency in Information Technology 38
GoPost Grading 10 weekly discussions worth up to 12
points each Total possible points is 120 Your score will be out of 100 points
Ergo, you may earn up to 20 points of extra credit
2012-03-28 Katherine Deibel, Fluency in Information Technology 39
More about Weekly Discussions
Late postings not accepted You can post multiple times and is
probably a good idea if you want to have a conversation
Summarizing topics is an easy 6 pts, but it is only 6 pts
I will be contributing as well
