I found problem on how to add text line in the middle of the hosts file. Just like below 127.0.0.1   localhost < i want to add text line here > xxxxxxxxxxxxxxx xxxxxxxxxxxxxxx and want to use 'sed', My friend, Sajal Kayan (God of Scripting) introduce me on ref#1, actually I quite not understand that. So he get me 2 approaches. #1   for each time i have to add text line, then do   >>> sed -i 's/127.0.0.1   localhost/127.0.0.1   localhost\n this is new line /' /etc/hosts   >>> sed -i 's/127.0.0.1   localhost/127.0.0.1   localhost\n this is new line 1/' /etc/hosts   >>> sed -i 's/127.0.0.1   localhost/127.0.0.1   localhost\n this is new line 2/' /etc/hosts   then we'll get   127.0.01   localhost   this is new line 2   this is new line 1   this is new line   this is good enough if we don't care about the order. But if you care , Sajal has 2nd approach #2   >>> sed -i 's/127.0.0.1

(Thank for http://permalink.gmane.org/gmane.comp.python.amqp.celery.user/1695) To create a queue? You know celery automatically declares queues right? You wouldn't 'create' a queue per se, you only declare them, in some context the queue is only actually created when a message is delivered to it. For some transports queues and exchanges *must* be declared by every process that uses them. If you use RabbitMQ then you can create a queue manually like this: from celery import current_app as celery from kombu import Queue, Exchange q = Queue("foo", Exchange("foo", type="direct"), routing_key="foo") with celery.broker_connection() as conn: with conn.channel() as channel: q(channel).declare()

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 psycopg2 in a virtualenv with --

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

The “sudo apt-get upgrade” isn’t necessary. It’s a different type of upgrade from “dist-upgrade” You either run one or the other. “apt-get upgrade” will only update your existing packages while “apt-get dist-upgrade” will update your existing packages, remove obsolete packages and install new available packages as well. You can get breakages either way since new packages might be required as dependencies for upgraded packages in the case of “sudo apt-get upgrade” so using “apt-get dist-upgrade” is still the best way so far. Note: This only applies to LMDE since LMDE is a true rolling release. For any other flavor of Mint you’d use MintUpdate levels 1, 2 and 3 all the way. Perhaps someday Clem and Co. will figure out how to tailor MintUpdate so it works properly in LMDE but considering the rolling aspect of LMDE, I’m at a loss as to how theyn would do that. ref http://b10gger.wordpress.com/2011/03/20/difference-between-apt-get-upgrade-and-apt-get-dist-upgrade/ (thank for this website)
