Just got dropbox installed on my Ubuntu workstation. Great way to share files with my Mac and other computers. Now I cant live without it. To install on Jaunty just edit /etc/apt/sources.list and add:
deb http://linux.getdropbox.com/ubuntu jaunty main
deb-src http://linux.getdropbox.com/ubuntu jaunty main
Then:
$ sudo apt-get update
$ sudo apt-get install nautilus-dropbox
That’s it!!!

BCC maps are handled in postfix by the following tags:
always_bcc = address
Deliver a copy of all mail to the specified address. In Postfix versions before 2.1, this feature is implemented by smtpd(8), qmqpd(8), or pickup(8).
sender_bcc_maps = type:table
Search the specified “type:table” lookup table with the envelope sender address for an automatic BCC address. This feature is available in Postfix 2.1 and later.
recipient_bcc_maps = type:table
Search the specified “type:table” lookup table with the envelope recipient address for an automatic BCC address. This feature is available in Postfix 2.1 and later.
So this is how I did it:
Added the following lines to /etc/postfix/main.cf:
sender_bcc_maps = hash:/etc/postfix/bcc_maps
recipient_bcc_maps = hash:/etc/postfix/bcc_maps
Edited the file /etc/postfix/bcc_maps :
monitorme@linuxzone.org admin@linuxzone.org
This way for all messages sent and received by monitorme@linuxzone.org, a copy will be sent to admin@linuxzone.org
Ran postmap /etc/postfix/bcc_maps
restarted postfix.

If you want mysql to have a different timezone than your server’s, here are the steps:
1) Run the following command to populate mysql’s timezone tables:
mysql_tzinfo_to_sql /usr/share/zoneinfo |mysql mysql
2) in the [mysqld] section of /etc/my.cnf, add the following line:
default-time-zone='US/Eastern'
(change US/Eastern with the desired timezone of course. It should match the format of /usr/share/zoneinfo)
3) Restart mysql
To check you mysql server’s time run the following query:
mysql> select now();
+---------------------+
| now() |
+---------------------+

This morning I read a twit about a blog post from xapbr.com (http://www.xaprb.com/blog/2009/03/25/mysql-command-line-tip-compare-result-sets/).
Pretty nifty tip on how to get a MD5 Checksum on a result set from a query. This can be very helpful when you are optimizing queries that return a very large set of results and you need to make sure they match.
mysql> pager md5sum -
PAGER set to 'md5sum -'
mysql> select * from test;

If you get this error when trying to access Log Manager, this happens because filemng which runs as psaadm user does not have permission to access the directory. You can get a similar error on the File Manager:
Error: Unable to change directory to /statistics: filemng failed: filemng: opendir failed: Permission denied
To fix this problem make sure psaadm is part of the psaserv group in /etc/group
