  1. CS 312: Introduction to Programming Vallath Nandakumar

  2. Agenda Introduction Administrative details Grades, Exams Discuss the scope of computer science, and what computer science professionals do Write a short Java program

  3. Who am I? Contact Office: GDC 6.314, 512-471-9288 vallathn@cs.utexas.edu www.cs.utexas.edu/~vallathn Education and work experience B.Tech, Indian Institute of Technology, Madras M.S., PhD (Electrical Engineering & Computer Science) University of California, Berkeley Tektronix Inc. Advanced Micro Devices Amrita University, India

  4. Course timings Lectures MWF – 10-11, 11-noon Discussion sections 12 sections, all on Friday Two sections conducted together (except for 10-noon timings) Led by two Teaching Assistants (Luis, Xiaolong) Three undergraduate Proctors for grading and assisting (Rebecca, Megan, Andrew)

  5. Startup Www.cs.utexas.edu/~vallathn/Fall2013/cs312/Startup.htm Request CS department account https://apps.cs.utexas.edu/udb/newaccount/ Read the syllabus and look over the schedule. Explore the class web page Sign up for the class discussion group on Piazza Register iClicker (not on Blackboard)

  6. Startup contd. Software, if working at home JDK, BlueJ (or other IDE) (optional) Practice-It account Excellent for practice. Do 10 or more per week. Get the textbook No need to get MyProgrammingLab 2nd edition has different exercises, but otherwise much the same. Might work for you.

  7. Graded course components Clicker participation 43 lectures with clicker, 1 point each: 43 points total Discussion section quizzes 11 quizzes, 10 points each: 110 points total Programming projects 12 projects, 1st 10 points, rest 20 points: 230 points total Two Midterms:150, 200 7 - 9 pm, Wednesday 10/2 and Wednesday 11/13 conflict? email me ASAP Final: 300 points, Day and Time TBD

  8. Graded course components contd... 43 + 110 + 230 + 150 + 200 + 300 = 1033 clicker, Quizzes, Programming Assignments capped at 350 points. 33 points of “slack” among those 3 components No points added! Grades based on 1000 points, not 1033 Grades posted to Grade Center on Blackboard Final grade determined by final point total and a 900 – 800 – 700 – 600 scale pluses and minuses if within 25 points of cutoff: 875 – 899: B+, 900 – 924: A- Some curving might be done at the end

  9. Assignments Start out easy but get harder Individual – do your own work Okay to share tests you write Programs checked automatically with plagiarism detection software Turn in the right thing - correct name, correct format or you will lose points / slip days Slip days 6 for term, max 2 per assignment don’t use frivolously

  10. Succeeding in the course Material builds on itself Failure to understand a concept leads to bigger problems down the road, so … do the readings start on assignments early get help from the teaching staff when you get stuck on an assignment attend lecture and discussion sections participate on the class discussion group do extra problems (Practice It! http://practiceit.cs.washington.edu/) study for tests using the old tests study for tests in groups ask questions and get help when needed

  11. Succeeding contd... Most important is to do lots of problems Only way to remember the concepts Reading and memorization of limited use Don't hesitate to explore, try out different ways of doing a problem Java has many features Don't hurry, unless it is a timed test Speed will come automatically Try to get program right the first time you compile and run it Focus on accuracy

  12. Common mistakes Not registering clicker at iClicker website Assuming final date and time already set Section number / unique id from UTDirect, not Blackboard Not turning in the correct thing on programming assignments Going to the wrong section

  13. Where to do programming (coding) can work in CS department microlab, 1st and 3rd floor of Gates, north wing (GDC) login via CS account name and password work on your own system if you wish Java Web page has details under Software. - JDK 7.0 Optional IDE. Recommended IDE is BlueJ or Eclipse, also free

  14. Residential Halls Study Groups Tutoring & group study for CNS majors: • Intro Chemistry • Including Organic • Intro Math (Pre-Calculus and Calculus) • Intro Biology • Including Genetics • Intro Computer Science Convenient Locations and Times: • Kinsolving & Jester West dorms • Sunday - Thursday nights: 7:30 - 10:30 PM • Questions? rhsg@cns.utexas.edu • Website: http://cns.utexas.edu/community/resident-hall-study-groups

  15. Are Programmers Geeks, or just Smart?(At least, we are not the pointy-haired manager!)From Dilbert, by Scott Adams

  16. First Clicker Question Your high school was In Texas Outside Texas

  17. What is Computer Science? Study how to manage and process information using computers, mostly digital computers

  18. Information processing Digital computers process information in discrete (countable units) Real world is 'analog', or continuous Height of a person, time taken to drive to work Computers like things to be well-defined Humans like fuzzy stuff I like you sort of, maybe, kinda ...

  19. Need to adapt human thinking “We will arrive in precisely 4.3829 hours, Captain” “You mean, like around lunchtime, Spock?”

  20. Programming a skill and tool that are applied to all other areas of computer science artificial intelligence, networks, cpu architecture, graphics, systems (programming languages, operating systems, compilers), security, and on and on … We will be using solving problems and implementing solutions in a programming language called Java problem solving and computational thinking are key

  21. Programming Language A method of communication where humans can tell computers what to do in language that humans can read, write, and understand, and computers can also read and understand

  22. Why are we teaching Java? Financial Sector: Top languages are Scala, Java, and C# Agency, Media, Advertising, and Design:   Top languages are Ruby, PHP, JavaScript, Java, and Objective-C Enterprise Applications and Operational Software: Top languages are Java and C# Research and Development, Scientific, and Academic: Top Languages are Scala, C++, Erlang and Python
