2. Welcome to COP3502: Introduction to Computer Science • Instructor: Yashas Shankar • Email: shankar@cs.fsu.edu • All e-mails must be from your CS account • All e-mails must start with “COP3502:” in the subject line • All e-mails must contain your full name • Office: TBA • Office hours: Tuesday,Thursday 11:00 AM - 12:30 PM

3. Acknowledgement • Parts of slides presentations used in this course are copied from slides presentations from previous instructors of this course • Mr. Daniel Chang • Dr. Sara Stoecklin

4. Syllabus & Class schedule • See handouts • Read syllabus & schedule carefully

5. Basic knowledge about computers • To utilize computers you need both hardware and software Hardware Desktop, laptop. Hardware Operating systems Windows XP, Vista, Unix, Linux, MaxOS Operating system Software Office, Photoshop Software

6. Hardware Central processing unit (CPU)  calculate, compute, etc. Random access memory (RAM)  store temporary data I/O device  input/output device

7. Software • Software  application that runs on a computer • Games • MS-word, excel, PowerPoint • Windows media player

8. Operating systems • Operating system  what makes applications run on a machine • Windows • Unix • Linux • MaxOS

9. Your first software for this course • SSH (Secure shell) • You will need this software to do your class material + homework • CS computer lab and ACNS computer lab have SSH • You can download SSH and install into your computer by visiting “system.cs.fsu.edu” • Click on “New user info” • Click on “SSH how to” • Read instructions and download the file • Install SSH • You will need SSH to create your CS account and you must have your CS account before Wednesday next week

10. How to use SSH • Click connect (should be the 4th icon on the top) • Hostname • garnet.acns.fsu.edu  everyone should already have this account • shell.cs.fsu.edu  have this CS account by next Wednesday • program.cs.fsu.edu • Use same account as shell.cs.fsu.edu • Use this server to do your programming homework • Click ‘connect’ • Enter password • Now you are in the remote host (garnet.acns.fsu.edu server, etc.)

11. How to use SSH (cont.) • Host • Garnet.acns.fsu.edu  your webpage • Shell.cs.fsu.edu  some of your homework • Program.cs.fsu.edu  your programming homework • Operating system  UNIX • You need to learn how to use UNIX • Unix example • ls – list files in the directory • cd – change directory • rm – delete files • mkdir – make directory

12. Your first homework • Install SSH into your computer • You can use SSH in computer lab, but I would recommend to install it on your computer since you will be doing a lot of homework this semester (don’t forget that homework count toward 50% of your grade) • Try SSH to garnet.acns.fsu.edu • We will start covering UNIX on Wednesday

13. Your first real homework • Get a CS account • You can start doing it this Friday (after the end of drop/add period, when the system group have the final roaster of CS students) • Send e-mail to me (shankar@cs.fsu.edu) with your CS account by 11:59pm next Thursday • This is all or nothing homework: you either get full score or zero • You may have around 20 homework's, so this will be approximately 2.5% of your final grade. Start working on it this Friday. • E-mail subject  COP3502: Assignment#1 submission • E-mail body  your full name

14. How to send e-mails • Obtain your CS account first • SSH to shell.cs.fsu.edu • Type ‘pine’ • Pine is an e-mailing program that you will be using throughout this course

15. How to use Pine • Send e-mails (compose) • At main menu type “c” • To  put e-mail address that you want to send to, e.g. shankar@cs.fsu.edu • Cc  when you want to put more than one address • I would recommend that you also send e-mail to yourself (put youid@cs.fsu.edu in the Cc field • Subject  subject of your e-mail • Always start with “COP3502:” e.g. “COP3502: questions regarding asg#1” or “COP3502: Assignment#3 submission” • CTRL-x  send

16. How to use Pine • Read e-mails • At main menu type “i” or select ‘folder list’ then ‘inbox’ • Select message to read, type “i” again to go back to inbox • Go to main menu • Type ‘m’ • Quit • Type ‘q’ • Attachment • In a compose message window, move your cursor to attachment, • CTRL-j  attachment • CTRL-t  to file (select files)

17. Before we leave today • What do I expect from you • Punctuality • Work hard • Honor • What else do I expect from you • Buy both textbooks • Write down lecture notes • Absolutely no cell phone use or ring in class • Always bring your textbook

18. Before we leave today • What can you expect in this course • You will have a lot of programming homework in the first half of the semester • Homework in the second half will be more ‘paper and pencil’ • There will be approximately 10 quizzes, many of them will not be announced in advance and many of them will be related to your homework • Many quizzes and (parts of)exams will be open-book • Again, always bring your text book • You cannot share textbook during a quiz/exam • You will have to print and hand-in many of your homeworks. Majors labs provide free prints for students that enroll in CS classes

19. Before we leave today • Late assignments are not accepted (you will get zero). There will also not be any make-up quizzes. • Extra credits • There are four extra credits. Two will replace two of your lowest homework scores. Another two will replace two of your lowest quiz scores. • One extra credit  write a 5 page summary of one chapter in Ethics for the information age textbook • Four extra credits  four chapters with 5 pages each • There will be no other extra credits • If you have less computer background than other students, you will have to work harder

20. Before we leave today • Try to be familiar with SSH before next class • We will cover basic UNIX commands in next class. If you have no idea what UNIX is, you should search it up from the internet before next class
