• Using the 'submit' command
• Submit your source code, Makefile, README, screenshots, video capture, and other files necessary to compile your code.
• To submit your files, type:
• submit cmps160-jed.f07 lab4 files
• Making the video capture for your lab
• Go to the directory /afs/cats.ucsc.edu/courses/cmps160-jd. There you will find the 'Capture Me' application. (You can also download it from the website: http://www.versiontracker.com/dyn/moreinfo/macosx/15496)
• Click on the Capture Me icon to get a 'Capture Me' window. You can drag this over to the part of the screen you are trying to capture. You can also resize using the lower right corner of the window.
• Each time you click inside the window, it captures what is behind this window. In order to record a video clip, first we need to change the settings a bit....
• Use command (apple key) + Tab to go to the Capture Me application. Then go to 'Preferences.' Under the 'Recording' Tab, change the Frames Per Second to 30 and change the recording time to 60 seconds.
• Now to record, simply use command + 'R'. You are now recording! The recording will automatically stop after 60 seconds or you can end it by pushing the 'Stop' button. The movie clip is then created on your desktop. If you want to save screen shots and not videos to the desktop, use command + 'S'.
• In lab demo
• You will be required to attend the lab session you are enrolled in to demo your submitted code to the TA's.
