Talking about technology (mostly)

Today learned about the dpkg -s command, e.g.

# dpkg -s kde-baseapps

To get the element/tag name with jQuery:

 $( '.selector' ).get( 0 ).tagName

In vim to undo is ‘u’ and to redo (i.e. undo undo) is ‘Ctrl+R’…

Found this which said:

$('<div/>').text('This is fun & stuff').html();

My CSS height value wasn’t being applied. Found this. The problem was that I needed to specify heights for all of the ancestor elements. Bug fixed!

I edited /etc/courier/authdaemonrc and added:

DEBUG_LOGIN=1

Then I created a mail.debug log file:

# touch /var/log/mail.debug
# chown syslog:adm /var/log/mail.debug

Then I created a mail.conf file for rsyslog in /etc/rsyslog.d/mail.conf:

mail.debug /var/log/mail.debug

Then I restarted the rsyslog service:

# service rsyslog restart

Now I have debug logs for mail services!

…oh, no, wait… I only have LOGIN debugging enabled.

Found this, edited /etc/courier/imapd-ssl and added:

IMAPDEBUGFILE=courier.log

Then restarted courier imapd-ssl:

# sudo /etc/init.d/courier-imap-ssl restart

Now there is a courier.log file in: /var/pcmail/jj5@progclub.org

Today I had an interesting problem.

When I ran:

 # php test.php | less

The ‘less’ program entered input mode and the up and down arrow (and j, k keys) weren’t working.

Eventually I figured out a solution:

 # php test.php < /dev/null | less

The PHP CLI seems to be interfering with the terminal and piping in /dev/null to PHP CLI stdin fixes the problem!

Downloaded Roundcube 1.0.2 and installed it at ProgClub…
