Introduction

• Tony White, Associate Professor– Office: Herzberg 5354– Tel: 520-2600 x2208– Fax: 520-4334– E-mail: arpwhite@scs.carleton.ca– Web: http://www.scs.carleton.ca/~arpwhite– Course: http://www.scs.carleton.ca/courses

Communication

• All course-related e-mail to have a subject line that contains the text “COMP 4101”

• All requests must be documented via e-mail, a verbal agreement is insufficient.

• Requests for extensions to an assignment or project deadline, changes in student lecture schedule must occur more than 24 hours prior to the deadline or lecture time. Failure to do this will result in the student being considered in default of the deadline.

• Notes for illness: I do require them.

Logistics• Lectures:

– Tuesday and Thursday 1:00pm-3:00pm, TB 236• Rescheduled classes:

– None yet …• Office Hours:

– Tuesday and Thursday 11:30am-1:00pm– By arrangement, with e-mail confirmation of professor’s

availability.• Assignments:

– Due by 11:55pm on date posted.– Late assignments will be not be accepted unless a deferral is

granted.– Submission is using Raven system

Course Expectations

• Final: 20%– Will consist of multi-choice, definitions, and programming

• Project: 35%– Objective: build a distributed application using course techniques– Teams of 3/4– Involves:

• Presentation (to class)• Written report, demonstration and group oral (with professor)

• Midterm: 20%– Will consist of multi-choice, definitions, and programming

• Assignments: 25%– 3 (or 4) assignments, submitted in teams of 2– Poor testing or inadequate documentation will be heavily penalized– 25% of assignment marks for testing and documentation

• Notes:– Assignments delivered using Raven system– JacORB Object Request Broker (ORB), JBoss, Eclipse available on epsilonXX

I provide:

• Lecture notes, study guides• Assignments• Assignment solutions• Course news

Plagiarism

Plagiarism n 1. A piece of writing that has been copied from

someone else and is presented as being your own work

2. The act of plagiarizing; taking someone's words or ideas as if they were your own

– If confirmed, student will be given zero marks for the piece of work and the incident will be reported to the Director.

• On a second offence:– If confirmed, the student will be given an “F”

grade for the course and asked to withdraw. The Director will be informed.
