Syllabus & Class schedule See handouts Read syllabus & schedule carefully
Basic knowledge about computers To utilize computers you need both hardware
and software
Hardware
Operating system
Software
HardwareDesktop, laptop.
Operating systemsWindows XP, Vista,Unix, Linux,MaxOS
SoftwareOffice, Photoshop
Hardware
Central processing unit (CPU) calculate, compute, etc.Random access memory (RAM) store temporary dataI/O device input/output device
Software Software application that runs on a
computer Games MS-word, excel, PowerPoint Windows media player
Operating systems Operating system what makes applications
run on a machine Windows Unix Linux MaxOS
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
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.)
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
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
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 ([email protected]) 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
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
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.
[email protected] Cc when you want to put more than one address
I would recommend that you also send e-mail to yourself (put [email protected] 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
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)
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
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
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
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
