I have a view of profile data that I want to sort by lastname. The name field currently has "firstname [middlename] lastname" in it. I looked around and found this example of using views php filter to sort based on a query.

Our aliases are spammed like any other account, but filtering on them would require making a real account. I wanted to be able to filter aliases without creating accounts for everything. My first solution was to create an account and filter on that one, then using $original_local_part I could forward to a filtered alias. This works but if someone discovers the filtered alias, they can bypass the filtering.

The leap second has had been a problem for Java apps (389-console for me) and apparently some ruby apps (seems like puppet ((can't prove it)) ). I found the common fix is to just set the date based on the current date as shown here.

Doing this on all the machines, a single line with func.

We are using gnarwl for vacation notification and I would like gnarwl to only reply if the current time is in the vacationStart vacationEnd window.

Here is the queryfilter to do that using the following information:

<br />
$recepient           - receiver of the message<br />
$time                - current time in seconds since the epoch

I often use dd to copy large files or make images from hard drives. It's annoying to watch something without any progress indicator, so I use the little known kill switch on dd.

From the man page:

Sending a USR1 signal to a running ‘dd’ process makes it print I/O statistics to standard error and then resume copying.

$ dd if=/dev/zero of=/dev/null& pid=$!

I wanted to monitor the ambient temperature in my computer room and decided to try using the built in sensors on my servers. ipmitool showed an ambient temperature, so I did some sed to get just the temperature.


[thomas@hotstuff: ~] $ sudo ipmitool sdr type "Temperature" |grep Ambient
Ambient Temp | 08h | ok | 7.1 | 22 degrees C

Update: I noticed that the syntax for vacationStart and vacationEnd do not permit integer comparisons. So I changed them from 1.3.6.1.4.1.1466.115.121.1.40 to 1.3.6.1.4.1.1466.115.121.1.15. This change allows you to make a gnarwl search string that uses the current time to check if a vacation is active.

This is just a case of RTFM but I thought I'd share...
