From the NYT.com:

That might help explain a shift in what college freshmen described as their primary personal objectives. In 1970, 79 percent said their goal was developing a meaningful philosophy of life. By 2005, 75 percent said their primary objective was to be financially very well off.

Three current events

Leave a comment here about your three technology article summaries if you didn't before.

Highest grade possible is a B.

Also leave your comment about Wikipedia here if you didn't do so. Here are the three questions:

1.) Who writes Wikipedia?

2.) How much does bias hurt wikipedia?

3.) Do you think Wikipedia is better for research than Google? Why or why not?

Before next Thursday!

Here is an extra credit opportunity.

ONLY USE THE FOLLOWING DISTROS IF YOU CAN INSTALL THE LINUX ON THE COMPUTER: You may download Ubuntu, Gentoo, Fedora, or Debian linux distribution and burn it to a CD. You will need a high speed connection for the download. Dial up is just too slow!



You need to keep a journal of the installation process.

Evaluate OpenOffice.org and write down your thoughts about five applications.

Compose your thoughts and print them out (minimum 400 words). Due next Thursday in class printed.

Three extra credit As!

compatibility program is now extra credit

If anyone wants to continue the "compatibility program" for extra credit, you can turn it in on Monday by yourself or with someone else.

We are focusing on the modules pretty seriously now. So we will put javascript specifically on the backburner for a bit. I hope you keep up your skills though...much of your midterm will be based on javascript! So if you were upset that I didn't give the quiz in class and you studied I hope you realize that those skills are very important to this class (and maybe your life).

Quiz Will Not be Tomorrow

Well I haven't posted the quiz review online because I will have a sub tomorrow.

So it'll be postponed until Wednesday.

I will leave the work for class on this blog tomorrow and you will work on your "Dating Program!"
SWBAT: design a "dating program." Divide the male names into A-F, G-K, L-Q, R-z (or any way you want) and divide the female names the same way. Obviously the real world is more complicated than this but we are doing a javascript based on nothing really. (If people take it seriously they really need some confidence.)

So after coming up with the 'compatible' partner for the person who entered the name, return both names in a prompt and whether they are compatible. You can add other variables.

Project due Friday at the beginning of class.

Here is the grading procedure:

Prompts 20 pts.
Comparison of two names 60 pts.
Output 20 pts.
Extra A in the gradebook for every variable you bring into the equation! This is a great opportunity for extra credit!

Nice summary of javascript

We'll read through this in class.

Second Homework:
Students are to create a program that asks users for the distance they are traveling and store it in a variable. Then you are to ask the user for the miles per gallon of their car. Store this in a variable also. Lastly ask the user how much gas they have and store this in a variable. With this information calculate whether or not they can make the journey with the amount of gas they have. If not suggest they fill up.

Create a MPG program:

  • Three variables: One for MPG, one for distance, and one for gas used.
  • Initialize the program first for the distance to Orlando and the amount of gas you believe would be used. Pretend the first vehicle is a Hummer.
  • Do calculation.
  • Display MPG to screen.
Once this is complete you need to prompt the user for the miles driven and the gallons of gas used. You will return the miles per gallon.

The Google Centered World?

It seems this is a good time to explicitly lay out my theory for this course and tie it in with what we've done so far.

This week we have been practicing with Microsoft's famous (or infamous) Office suite. We've designed simple spreadsheets to manipulate stock market data with Excel. We've designed databases with Access to keep track of students and their records. We used Publisher and Word to write pamphlets to explain the stock market to the uninformed (what a task!).

But there was a problem. We had to think of ways to publish the information. The information wasn't easily shared with others, without email! Historically Microsoft was surprised by the speed at which the Internet changed the PC and society. Today it seems Google is at the forefront in allowing people to quickly share their ideas quickly. For instance, Google bought Blogger, the site I'm now using, and runs it ad-free. So why did they purchase it? How does it benefit them if it costs nothing to sign up and no ads run on the blogs at first?

This course will not be an advertisement for Google's services (except for this one time: they are awesome). But it won't be an advertisement for Micrsoft either. I taught for a couple of years at a local college and I was dismayed at the way the courses were structured and especially displeased with the boring, Microsoft-centered textbooks. Professors were pretty much limited to Microsoft software. There was never any discussion of open source software. The courses seemed outdated and professors and students were not encouraged to venture far from the safety of Microsoft's shadow.

This course isn't about a software company in California or a software company in Washington. This course is about solving problems. Let's say you own a business, how can you use a spreadsheet to analyze decisions? How can you ensure that the data in a database isn't corrupted? How can a wiki benefit an organization?

This course isn't just about using computers for commerce either. There are social implications as well. Are people overwhelmed by a certain level of data? How will instant communication change relationships?

With all this said, I'm happy with the way the year started out. Keep in mind the pseudocode from the beginning of the year. Computers use algorithms to solve problems. Remember the way computers must be told every step. Loops and if statements are just ways of solving problems.

I'm happy with the interest in the stock market game. I'm planning on using the data in a few months for a project. I'm wondering if students who traded more do better than people who just leave the stocks (perhaps they just forgot their password?). Maybe we can draw a connection with the data. Maybe not. We'll see.

I sent out gmail invitations today but I got a lot of emails bounced back. Everyone will need a gmail account by next Monday. It's for a grade: A, you have an account- F if you don't. The if statement is simple. So is getting the account.

With all that said, today we'll be learning the basics of HTML in order to make "About Me" web pages...

IT 2020


First of all I'm excited about this course. IT is the cutting edge of technology.

The best way to learn is to stay current using reputable sources online. Textbooks may provide general knowledge, but for sheer speed they can not match the web obviously.

What sites am I referring to? First of all, www.slashdot.org provides a great message board for discussing current events in IT. The nytimes is another great site.

Here is a site that has many good free articles but many require login:
http://www.technologyreview.com/. Then there is the great aggregator of news: news.google.com.

Commenting on current events on your own blog (go to http://www.blogger.com and make one now. Write down the password and username- don't show anyone.) will be an important part of this class.

Next we are going to start with the basics of computer science. No, we are not going to focus on merely ONE language. My aim is to give you the framework to handle ANY language and ANY problem.

Let's start with the problem:


You will define the problem using pseudocode.

Let's pretend the first program is to make a sandwich.

What will you need first? What will you need to do?

Discussion followed by blog post.
