59pm on Wed or Fri evening Electronic handins using Autolab no exceptions Makeup exams and assignments OK but must make PRIOR arrangements with Prof O Hallaron Appealing grades 6 Within 7 days of due date or exam date Labs Talk to the lead person on the assignment Exams Talk to Prof O Hallaron 15 213 F 06 Cheating What is cheating Sharing code either by copying retyping looking at or supplying a copy of a file Coaching helping your friend to write a lab line by line What is NOT cheating Helping others use systems or tools Helping others with high level design issues Helping others debug their code Penalty for cheating Removal from course with failing grade Detection of cheating 7 We do check and our tools for doing this are much better than you think 15 213 F 06 Policies Grading Exams 40 Two in class exams 10 each Final 20 All exams are open book open notes Labs 60 7 labs 6 12 each Grading Characteristics Lab scores tend to be high z Serious handicap if you don t hand a lab in z We offer generous redemption programs 8 Tests typically have a wider range of scores 15 213 F 06 Facilities Labs will use the Intel Computer Systems Cluster aka the fish machines 15 Pentium Xeon servers donated by Intel for CS 213 Dual 3 2 Ghz 64 bit EM64T Nocona Xeon processors 2 GB 400 MHz DDR2 SDRAM memory Rack mounted in the 3rd floor Wean Hall machine room Your accounts are ready Getting help

06 Lab Rationale Each lab should have a well defined goal such as solving a puzzle or winning a contest Doing a lab should result in new skills and concepts We try to use competition in a fun and healthy way 17 Set a reasonable threshhold for full credit Post intermediate results anonymized on Web page for glory 15 213 F 06 Autolab Web Service Labs are provided by the Autolab system Autograding handin system developed in 2003 by Dave O Hallaron Apache Web server Perl CGI programs Beta tested Fall 2003 very stable by now With Autolab you can use your Web browser to 18 Review lab notes clarifications Download the lab materials Stream autoresults to a class status Web page as you work Handin your code for autograding by the Autolab server View the complete history of your code
