1. lookup

As mentioned during the HTCLAGS talk, the lookup program does not work
on the FC3 machines yet. You can get a workaround by putting the
following in your shell initialization:

alias mylookup "ldapsearch -H ldap://ldap.srv.cs.cmu.edu -b \
dc=cs,dc=cmu,dc=edu \
-QLLL '(|(uid=\!*)(&(cn=*\!**)(!(cn=*-*))))' mailRoutingAddress cn"

Then, mylookup <user> does the right thing.

2. MATLAB

It was also mentioned that we don't have working MATLAB on the FC3 machines yet. You can get around that by running MATLAB as

env MATLAB_JAVA=/afs/cs/misc/jre/i386_rh80/1.4.2/libexec/j2re1.4.2 \
matlab -arch=glnx86

Thanks to Jeff Baird for suggesting these workarounds.
