Regular Expression to find HTML links with title attributes
I recently needed to write a regular expression to find HTML and XHTML links with title attributes (<a href="http://www.gustavus.edu" title="Visit the Gustavus Adolphus College homepage">Gustavus</a>). Here it is: <a[[:print:]]*title=('|"")?(.*?(?=1))1?[[:print:]]*>([[:print:]]*)</a> Note that the [[:print:]] parts are applicable to ColdFusion regular expressions and would have to be changed to something else if you aren’t using ColdFusion. Additionally, […]

Heartbeat on Fedora Core 4
Here are the steps I took to get heartbeat ( from linux-ha ) to run on Fedora Core 4 (fc4). It is by no means a clean install, but it appears to work for us at the moment. First download the RPM’s from http://www.ultramonkey.org/download/heartbeat/. I am using version 2.0.2 today. Then I installed curl to […]
Friday Maintenance
For the past few weeks the load on our email servers, specifically the ones responsible for imap/pop/webmail, have been unable to keep up with the increasing demand. Thus causing access to imap/pop/webmail to be unavailable during times of peek usage. Delivery of email was not affected. To help alleviate the issue, we have spent the […]
Daylight Savings Time
Since the time change for the end of daylight savings last month, our iCalendar files on the college calendar have been using the wrong time. This was caused by our usage of a constant timezone modifier for adding to event start times and end times. As a result, whenever someone had added an event to […]
Friday’s Upgrades
Every day it seems like we are sending and recieving more and more email. That means every day our email system is more and more loaded. A couple of weeks ago we hit the limit as to how much email our disks could handle for everyone’s inboxes. We store all the users inboxes on a […]
Horde, IMP, and imapproxy
So it turns out that the cache in imapproxy that we turned on yesterday has a problem. First of all, it seemed to work great. I think webmail was more responsive and there was a reduced load on our mail disks. However not all was well. It seems like some times when you deleted a […]
Email performance
As many people have noticed, email performance during our peak usage time (9:50am-10:20am) has been extremely poor. The main reason we believe is that the disk drives our email inboxes are stored on are just not fast enough. Currently we are using a Sun T3 disk array with a 1Gig cache and 9 fibre-channel disk […]
