CS1315: Introduction to Media Computation

1. CS1315:Introduction to Media Computation Introduction to Course & Administrivia

2. Lecturer • Bill Leahy • email: bleahy@cc.gatech.edu • Office: CCB 113 • Office Hours • Monday/Friday: 10:00 - 11:00 • Tuesday/Thursday: 1:30 - 2:30 • and by appointment

3. History and Purpose of Course • Created in response to attitudes about CS1321, and CS1, nationally • Goal is to teach computation in terms relevant to non-CS and non-ECE majors • Inspired in part by ECE’s DSP First • Developed with an advisory board from across campus: LCC, Applied Physiology, Math, ECE, CETL

4. Caveats • This course is differently paced than CS1321 • The content is different: Less programming, more math, more general CS concepts (like networking) • However, you WILL still be asked to learn to program! • You will not have fulfilled the pre-requisite for CS1322 by taking this class • But CS1316 (Representations of Structure and Behavior) will be offered this Spring, and that fulfills the pre-req for CS1322

5. Course Objectives • Students will be able to read, understand, modify, and assemble from pieces programs that achieve useful communication tasks: Image manipulation, sound synthesis and editing, text (e.g., HTML) creation and manipulation, and digital video effects. • We will always give you examples to use when we ask you to program • Students will learn what computer science is about, especially data representations, algorithms, encodings, forms of programming. • Students will learn useful computing skills, including graphing and database concepts

6. def clearRed(picture): for pixel in getPixels(picture): setRed(pixel,0) def greyscale(picture): for p in getPixels(picture): redness=getRed(p) greenness=getGreen(p) blueness=getBlue(p) luminance=(redness+blueness+greenness)/3 setColor(p, makeColor(luminance,luminance,luminance)) def negative(picture): for px in getPixels(picture): red=getRed(px) green=getGreen(px) blue=getBlue(px) negColor=makeColor(255-red,255-green,255-blue) setColor(px,negColor)

7. def chromakey2(source,bg): • for p in getPixels(source): • if (getRed(p)+getGreen(p) < getBlue(p)): • setColor(p,getColor(getPixel(bg,getX(p),getY(p)))) • return source

8. How grades will be determined • Lablets - five (10%) • Pre-quizzes and quizzes - three (15%) • Pre-quizzes are worth 20 points, quizzes 80 • Pop-quizzes with PRS (5%) • Homework - six (20%) • Take-home exams - two (10%) • Two in-class midterm exams and one final (40%) • Two in-class midterms are 20% (10% each) • Final is worth 20% • OVERALL: Grades are straight scale: 90-100 A, 80-89 B, 70-79 C, 60-69 D, 59 or below F

9. Collaborative for Learning,Non-Collaborative for Assessment

10. Collaboration ≠ Copying

12. Lablets (called Labs on swiki) • How to use your computer to do useful things • Word, Excel, PowerPoint, HTML • On your own computer (not in a lab) • At the request of your major • Collaborative

13. Pre-quizzes and quizzes • Pre-quizzes are collaborative: Work on them with your friends to learn the material • Quizzes will be very similar in content, but in class (15-20 minutes), individual work

14. Homework • Programming assignments • Designed to take no more than a couple hours each • Collaborative • Use these assignments to learn!!! • No Late Assignments Accepted AT ALL (without prior notification) • Assignments due at 7:00 pm on due date

15. Take-home exams • Programming assignments, about the same level of difficulty as homework • NOT AT ALL COLLABORATIVE • You may not talk to anyone about it • You may not have another student write it for you • You may not work with anyone • You may not look at one another’s code • THIS IS AN EXAM!

16. Midterms and Final • Two midterms • Both all-class-period long • Final is worth more than the midterms

17. Class website • http://coweb.cc.gatech.edu/cs1315 • This is where you’ll find everything associated with the class—editable by you! • Syllabus • Homeworks/Projects/Labs • TA Information • Soapbox and Personals • Announcements (You are responsible for these! Check daily!!)

18. Text • Book from Pearson:“Introduction to Media Computation:A Multimedia Cookbook in Python” • SECOND EDITION • First edition has about 80% same content, but chapter and page numbers will be different • CD with software and media attached to book • JES (our programming environment) also on CoWeb

19. PRS • Everyone is required to purchase their own PRS transmitter (from the bookstore) • You can use one that you already own, if you do • We will have frequent questions (mini pop-quizzes) in lecture. • Sum of these will be worth 5% of your final grade.

20. No Cell Phones or Pagers Permitted • Emergencies happen • Let me know before class if you are expecting a phone or page and need to leave it on • But in any event, if you get a call or page, you are expected to LEAVE THE LECTURE.

21. COME TO CLASS! • Approach of the class is apprenticeship • I’ll demonstrate a lot of what you need to do • You will see me make mistakes. • You will also see how to fix them • If you’re not here, you will not see the demonstrations

22. Organization of the class • Mandatory lectures Monday and Friday in large lecture hall format • Save the Wednesday for tests and maybe help sessions. • Mandatory breakout sessionsbetween lectures • In smaller (~50 student) sections • Emphasis on demonstrations, Q&A, etc. • You are welcome to bring your laptop for hands-on help

23. START LAB 1! • It’s due Friday!

24. TALK TO Us! (Please!) • We really want to know if the class is working and how it doesn’t work • Comment areas on CoWeb • Anonymous areas on CoWeb • Office hours, recitations, etc.
