Proper install guide I try to install psycopg2 (2.4.1 bcoz 2.4.2 does not work with django 1.3) on Ubuntu Natty today and got ImportError: can't import mx.DateTime module . Hmm... weird. I googled around and found a sequence of command to do a proper installation of psycopg2. $ sudo apt-get build-dep python-psycopg2 $ virtualenv ENV $ source ENV/bin/activate $ easy_install psycopg2 $ easy_install egenix-mx-base ref: http://www.saltycrane.com/blog/2009/07/using-psycopg2-virtualenv-ubuntu-jaunty/ Damn mx and psycopg2==2.4.1 The sequence of commands above did not fix my ImportError: can't import mx.DateTime module . I wasted a day searching until i found its defect on psycopg2 issue tracker . In sum, if you try $ ls /usr/include/python2.6/ | grep mx and you found that you have mx folder there, you're screwed. Psycopg2 will try to use this damn mx instead of default datetime package and that will prevent you from installing psycop...

Exit codes and kill-job signals The exit code from a batch job is a standard Unix termination status, the same sort of number you get in a shell script from checking the " $? " variable after executing a command. Typically, exit code 0 (zero) means successful completion. Codes 1-127 are typically generated by your job itself calling  exit()  with a non-zero value to terminate itself and indicate an error. In BaBar we don't make very much use of this. The most common such value you might see is 64, which is the value used by Framework to say that its event loop is being stopped before all the requested data have been read, typically because time ran out. In recent BaBar releases you might also see 125, which we use as a code for a generic "severe error"; the job log should contain a message stating what the error was. Exit codes in the range 129-255 represent jobs terminated by Unix " signals ". Each type of signal has a number, and what's r...
