Computer + Math + Language

Happy New Year! Happy New Blogging!

This blog is now posted once a week. Each week will answer questions related to Computers, Mathematics, and Schools.

Who Wants To Be A Programmer?

So you want to be a computer programmer or software developer. You're thinking you could start with $60,000 a year salary after you graduate with a bachelor degree in Computer Science. But do you really want to study all that hard and spend the rest of your working life in front of the computer day and night? Didn't you wrote a school report for your teacher on what you want to be when you grow up? Then here are four answers that can help you decide your answer to the question.
A. I want to be a physician so I can heal sick people and be a wealthy doctor.
B. I want to be a politician so I can be president and rule the world.
C. I want to be a programmer so I can create the next Minecraft and be a millionaire.
D. I want to be a poet so schoolchildren will write of me in their school reports.
What is your final answer?

Who Is The Greatest Mathematician In The World?

There are many people who have brought our knowledge of mathematics to what it is today. Thanks to that person or persons who had the idea of using stones for counting sheeps so shepherds will know when to look for a lost sheep. Thanks to Euclid for Geometry so high schoolers will have some real challenging homeworks. Thanks to Boole for inventing binary algebra so Turing can be called the father of computer science and have everyone buy home computers. But if one is to choose the greatest mathematician of them all, he or she has to be one who has helped the most people understand and learn mathematics. That accolade goes to Rene Descartes who invented the Cartesian coordinate system, which makes understanding calculus, drawing on a screen monitor, plotting on a graph, and other things palatable.

What Should Be The Universal Language Of The Whole Wide World?

If everyone in the world know how to speak one common language, then one can go anywhere in the world and be able to speak to anyone in the world without sounding like a foreigner. But what should be that one common universal language for everybody to learn. Should it be the one that more than half of the world already know? Chinese, anyone? Should it be the one that is easiest to learn? This depends on what language you already know. Should it be the one that is easiest for computers to know, or rather, to write in? Most computers are written in computer languages adapted from the English language, using only a hundred or so English words, and using only 26 letter characters, more than enough to fill a keyboard. Actually, the default or de facto universal language is already English, thanks to Shakespeare, Hamlet, and Romeo and Juliet.

ENG 223 Horror

ENGLISH ENG 223: THEMES OF LITERATURE

English 223 is a college course that studies different topics in the themes of literature. One of these theme is horror fiction. There are actually people whose job it is to study old literature and write a book on it. It keeps classic literature alive in the hands of new college students who are either majoring in English or in another major.
 

Troll 2 is a good horror movie if you're a kid who doesn't go for the gory details but would rather see the oozy details of a horror movie. And this movie has a lot of liquid green slime oozing out from poor unfortunate souls. This movie would be good to watch with young kids rather than those rated R horror movies spreading entrails all over the place.

Here's a practice exam on ENGLISH ENG 223: THEMES OF LITERATURE.

Question 1, 2, 3. Name 3 poems by Edgar Allan Poe with death as the theme?

Question 4. Who wrote the novel Frankenstein?

Question 5. Name the nobleman that inspired the Dracula character by Bram Stoker?

Question 6. Are ghost real?

Question 7. What type of bats drink blood?

Question 8. Are werewolves real?

Question 9. Who is the ancient Greek story teller that makes wolves speak?

Question 10. Name the play where William Shakespeare wrote of fairies?

Happy Halloween!

TA 152 Theatre

THEATRE ARTS TA 152: ANALYSIS OF DRAMA AND THEATRE

Theatre Arts TA 152 is The Analysis of Drama and Theatre course. It has no prerequisite. I actually attended this course one day in CSULA as an elective course. Here is an analysis of the movie I saw yesterday.

I watched the movie "How to Succeed in Business Without Really Trying" on TV last Sunday, and I enjoyed it. The movie is about our hero starting his way up to the corporate ladder in the mailroom department. This plot makes this movie special to me because I also started my way up in the mailroom department when I was 16 years old.

Robert Morse, who has the leading role, is so much like Jerry Lewis that for the first 10 minutes of the movie, I thought it was Jerry Lewis. Not until the movie showed a larger face did I realized the face is not that of Jerry Lewis.

Our protagonist started as a mailroom clerk, same as I did, then was promoted to junior executive, then junior executive with his own office, then director of personnel department, then vice president of advertising, then chairman of the board, all within a month or so. What a career!

It should also be noted that the Frank Sinatra song "I Believe in You" with the notable lyrics of "cool clear eyes of a seeker of wisdom and truth" and "grin of impetuous youth" came from the Broadway musical of this movie.

Lastly, the movie "How to Succeed in Business Without Really Trying" was followed 2 decades later by another movie using almost the same plot and starting in the mailroom department, “The Secret To My Success.”

Here's a practice exam for Theatre Arts TA 152: Analysis of Drama and Theatre.

Question 1. Who is the actor in the leading role in the movie “The Secret to My Success”?

Question 2. What year was the movie “The Secret to My Success” released?

Question 3. What year was the movie "How to Succeed in Business Without Really Trying" released?

Question 4. What song was the character "Finch" singing to himself?

Question 5. Who was the leading female actor in the movie “The Secret To My Success”?

Question 6. How old is the movie industry, in centuries?

Question 7. What standard equipment did all the junior executives in the movie "How to Succeed in Business Without Really Trying"  have in their desks?

Question 8. What does WWW company stand for in the movie "How to Succeed in Business Without Really Trying"?

Question 9. When did Theater Arts began?

Question 10. Who were the first playwrights?

The show must go on.

CIT 211 Windows 8.1

COMPUTING AND INFORMATION TECHNOLOGY CIT 211: WINDOWS 8.1

CIT 211 is a course to prepare users for the Windows 8.1 workstation certification. A server certification is a different course.

Last Wednesday, the computer prompted me a message from the Taskbar with the string "Windows Defender needs to scan your computer". It was the first time I've heard of that request. I clicked it and the computer did some stuff.

Here's a summary of the events before and after this task:

Precondition: I had Windows Defender do a quick scan of the computer twice inside a 3-day period.

Post-condition: No threat was found.

Post-condition user action: Updated windows. Closed lid for 15 seconds. Screen stayed black for 30 seconds.

Post-condition prompted by computer an hour later: Update available. Click to install.

In the Update and Recovery - Windows Update window, the following are displayed:

Most recent check for updates: 10/14/2015

Updates were installed: 6/1/2015

From these dates, it looked like I have not been installing the updates, only downloading them. And so it seems.

Here's a practice exam for CIT 211: WINDOWS 8.1 CONFIGURATION 

Question 1-5. What are the steps to install the downloaded updates for Windows Defender?

Question 6-10. What are the steps to configure a Windows 8.1 computer to check for updates but to let the user decide whether to download the updates?

You learn as you go.

IS 115 RAPTOR

INFORMATION SYSTEMS IS 115: INTRODUCTION TO PROGRAMMING

IS 115 is Introduction to Programming. It is the first course in learning how to write computer programs. IS 115 uses the RAPTOR and Python programming languages to teach programming. RAPTOR is a graphical flowchart programming environment. Python is a text-based programming language.

Here’s a practice exam or homework for INFORMATION SYSTEMS IS 115: INTRODUCTION TO PROGRAMMING.

Write a program in ANY programming language that fulfills the following requirements (solution is shown in Raptor):

Requirement 1: Do not use loop. Ask user to enter the numerators and denominators of 2 fractions.

Requirement 2: Do not use loop. If user enters a number other than 2, 3, 5, and 7, end program abruptly, otherwise output the product and the quotient of the first and second fractions.

Requirement 3: Do not use loop. Do not reduce the resulting fractions. Show and have your program tested by the tutor.

EXAMPLE: THIS IS ONLY AN EXAMPLE:

Enter numerator n1: #

Enter denominator d1: #

Enter numerator n2: #

Enter denominator d2: #

n1/d1 * n2/d2 = #/# and n1/d1 / n2/d2 = #/#

Extra and optional program (no solution shown): Reduce the resulting fractions WITHOUT USING A LOOP.

Go with the flow.
