Java tip (based on a student post to course newsgroup in an earlier offering of the course):
To get code running with java 1.6 on stdsun you'll need to use the
'subscribe' command to subscribe to JDK6, but then you'll receive some
heap size errors. I emailed the cse help desk about it and got the
following response:
"You can adjust your heap size by invoking the settings
parameters. They are:
-Xms512k (memory heap start size 512 kilobytes)
-Xmx1024m (memory heap max size 1024 megabytes)
Both should be invoked at the same time and you may test
different heap sizes. Our recommendation is 16m to start and
256m to max."
What worked for me (I couldn't figure out a way to set this
permanently), was to use java calls as "java -Xms16m -Xmx256m somefile".
