11. Policies You are expected to attend lecture, recitation and lab Students scheduled for lecture have priority for seating Must attend scheduled recitation and lab unless prior arrangements have been made. Courtesy No cell phones No beepers Be on time No whispering No alarms

12. CS 2130 Rules and Regulations 1. Academic misconduct is taken very seriously in this class. We will analyze what you turn in against other students submissions in the current semester as well as previous semesters. Unless otherwise instructed, you are required to do your own work without looking at other students code no matter what the source is. You are also expected and required to report any incidents of academic misconduct to the course instructor or to the Dean of Students responsible for Academic Misconduct. Failure to do so is in itself Academic Misconduct.

13. CS 2130 Rules and Regulations 2. You are responsible for turning in assignments on time. This includes allowing for unforseen circumstances. You are also responsible for insuring that what you turned in is what you meant to turn in. Jaws includes a getback feature: This allows you to retrieve exactly what you submitted and insure that it works. Take advantage of this feature. 3. In general, programming assignments should be turned in with a Makefile and all files needed to compile and run the program. The TA grading your submission should be able to make and run your program without adding files, repairing things etc.

14. CS 2130 Rules and Regulations 4. Tests and examinations must be taken at the scheduled date and time. Please do not ask for special treatment because you (or your parents) have purchased non-refundable airline tickets. The safe time to travel is at the end of or after finals week. The finals schedule published at the beginning of the semester is TENTATIVE. The official schedule gets published very late in the semester.

15. CS 2130 Rules and Regulations 5. If you need a certain grade in order to stay in school, maintain a scholarship, etc. the time to worry about this is right from the beginning of the course not during the week before finals. Grades are based on demonstrated performance not individual need based on factors external to the course. Please do not request special consideration based on this type of situation. 6. Final grades will be available from OSCAR normally sometime the week after finals. You may review your final and discuss your grades during the following semester in which you are attending Ga Tech. Grades will not be discussed over break.

16. CS 2130 Rules and Regulations 7. If you have any personal problems (family/illness/etc.) please go to the Dean of Student's (Gail DiSabatino) office located in the Student Services Building (Flag Building) next to the Student Center. She is equipped and authorized to verify the problems and she will issue a note to all your instructors making them aware of the problem and requesting whatever extension, etc. is necessary.

17. CS 2130 Rules and Regulations 8. The .announce newsgroup should be read every day. Official announcements about course matters will be posted there. The other course newsgroups are for posting technical questions about assignments, tests etc. Complaints, questions about your personal problems, etc. should be discussed with your instructor in person or via email.

18. CS 2130 Rules and Regulations 9. Out of consideration to your fellow students please turn off cell phones, beepers, writwatch alarms, etc. Also, make every effort to be on time for class. If you unavoidably late, please sit near the back and try to avoid as much disruption to the class as possible. 10. If you are graduating and need this course to do so please inform your instructor as soon as possible. 11. Complaints about any aspect of the course should be directed to the course instructor during office hours or via email.

19. CS2130 Submissions must Compile Not produce any warnings when compiled with gcc -Wall -O2 -ansi -pedantic Not produce any splint messages Note: Run splint against all files to be submitted Not core dump, seg fault, etc. Not produce spurious output Not leak memory

23. Evaluation Participation (PRS) 10% Homework (Collaboration) 10% Labs 20% Project 10% Tests (2 @ 15%) 30% Final 20% Total 100%

24. Participation Will be using PRS (Personal Response System) Allows multiple choice questions, surveys Grade based partly on answering questions partly on answering questions correctly Do not walk off with units Do not break units ($60) More later

29. Official Syllabus Available on the class web page

30. Languages & Translation Learn C Programming Language Portability Systems programming capable Widely used in Ga Tech CoC Gets close to machine Translation & Interpretation Heart of computer science Key concept Widely used

31. Getting Your Account If you have an active CoC account do nothing! Example: sk8r.boi@cc.gatech.edu If you already have a CoC account and it's inactive You need to go to CNS (CCB 140) and get it reactivated If you have never had a CoC account request one via the web: http://www.cc.gatech.edu/cns/forms/account_form.html

32. Programming Environment All programs written and tested in a "UNIX-like" programming environment UNIX written "by programmers, for programmers" Support for C programming Good software tools Crash-resistant

33. What flavors of UNIX? Officially supported platform (programs will be tested and graded here) Red Hat 9.0 Linux Available on helsinki, CoC labs, or install at home

34. What flavors of UNIX? Unofficially supported (may be used for some development work, but test it on an "official" platform before turning in!) Mac OS X Cygwin on Win 9x/NT/2000/XP Solaris 8 (lennon) Install at home

35. Installing Software Installing Solaris Intel version (x86) can be downloaded free http://www.sun.com/software/solaris/binaries/ Not recommended unless you enjoy pain Installing Redhat 9.0 Most accurately duplicates lab environment Requires separate disk drive or partition (back up your hard disk!) Free CDs available from Linux Users Group (LUG) http://www.lugatgt.org/ Or download from Georgia Tech Linux FTP site ftp://ftp-linux.cc.gatech.edu/pub/Linux/index.html

36. Installing Software (cont) Installing Mac OS X Easiest to install for Mac users (uses existing disk partition) If you are a Mac user, you will have to get it eventually anyway, so why not start now? Disadvantage: only one that's not free :-( Installing Cygwin Easiest to install for Windows users (uses existing disk partition) Two versions: Command Line http://sources.redhat.com/cygwin/ X Windows http://sources.redhat.com/cygwin/xfree You are running in a linux-like environment not linux!

37. Requirements for Assignments All programming assignments must compile cleanly (i.e. no warnings or errors) with gcc -Wall -O2 -ansi -pedantic splint cleanly exit gracefully produce useful output where applicable Capital crimes (== automatic 0) non-compiling or non-linting programs core dumps (or any ungraceful exit) infinite loops excessive spurious output

38. Course Philosophy Self-reliance CS 1/CS2 offer certain amount of hand-holding This is the first "real" CS/CmpE Course Preparation for real world Figure it out!

39. Chain of Command Textbook Online Manuals (RTMP...see man man) Web Search Engine Newsgroups TA/STA Head TA's Sect A (Noon) Jason Whitehurst (jasonmac@cc.gatech.edu) Sect B (6 pm) Geoff Meyers (jinx@cc.gatech.edu) Bill Leahy

40. Keys to Success Do all assigned readings and work Slackware is just a catchy name Form a study group Start early Use the resources EXPERIMENT!!! Remember: This is Computer Science not Rocket Science Debugging is 90% psychological

41. Questions?

42. The Rainfall Problem First used by Elliot Solloway at Yale Depressing results Situation hasn't changed much New head-on approach!

43. The Rainfall Problem Write a program that will read in rainfall values (decimal numbers) Ignore negative values Terminate on greater than 999.0 Print out average rainfall
