Update on server downtime 
Over the last couple of weeks my server hasn't been the most reliable (and I'm still having an issue with it when it has to boot back up, but since it is rarely turned off anyways, this isn't too big of a deal), but I've found the issues and had ...
Unexpected Downtime
So over the last couple of days the leifmadsen.com website, blog, and PBX have been down since it seems the server they run on has been locking up on me. I've since done some maintenance on the server, but I'm not entirely convinced I've actually fixed anything.
Currently it is up ...
Using DUNDi to precache results upstream
I will be sure to expand this out to a better document, but here is a response I gave on the Asterisk bug tracker after attempting to verify if there was an issue with precaching on Asterisk:
Aha!
This is a configuration issue. And the nuances are subtle because I got caught ...
Instructions for Building Asterisk 1.6 and trunk
These are instructions for building Asterisk trunk and it's dependencies for testing purposes.
Introduction
So I went through the process today of installing Asterisk trunk (which will pretty much apply without exception to any Asterisk 1.6.x release) on a CentOS 5.2 minimal install today. I ran into a couple of issues that ...
Importing new CA root certificate (RapidSSL) into Nokia E61i
So for the last year or so I've been stumped with trying to get my work email to sync on my Nokia E61i. At work they are using Zimbra as the email server, and I've had problems with the "This site has sent an untrusted certificate" message which causes me ...
Why Cluster? Video from AstriCon 2008
I recently spoke at AstriCon 2008 in Glendale, Arizona about Asterisk clustering, and it happened to be one of the presentations that was recorded. Apologies for the low quality and low volume, but hopefully I'll be getting a copy of the raw video in the near future. Additional apologies for ...
How to list which view’s you’ve created in MySQL
Here is a very handy post I found on a MySQL site. It allowed me to show how to list the views I had created, and how to describe how they were created from the MySQL console.
# list all views
SELECT TABLE_NAME
FROM INFORMATION_SCHEMA.VIEWS;
# describe view
# replace ? with view name
SELECT VIEW_DEFINITION
FROM ...

Ignoring files in subversion
I've seen the section in the subversion book about setting properties for directories so that I could ignore certain files. For some reason it never really clicked for me, and I never understood how to do it. But my friend Enrique told me simply how to ignore all the files ...
OpenVPN Client on DD-WRT
So I've been trying to get OpenVPN connected as a client to my work today, and now that I have it working I wanted to share with you how I did it. This is more of a note of how I did it so that I know how to make ...

2008/09/11 Leif Madsen Speaks at AstriCon 2008!
I will be speaking at AstriCon 2008 in Glendale, AZ on Wednesday, September 24, 2008 from 11:00am-11:45am in the Carrier/Large Scale track. The presentation will be an updated version of my Why Cluster? presentation. More information is available here and you can read my biography here.

2008/04/22 Leif Madsen spoke at IT360 (again!)
The last update I had was almost a year ago. Since then I've spoken at AstriCon in Carefree, Arizona and at IT360 again this year in Toronto where I had the opportunity
to deliver the same content for those who were unable to make it to AstriCon this past year. In addition, I did add some updated sides at the end, with the majority of the content still being quite relative. The presentation is available Why Cluster? An Introduction to Asterisk Clustering. I've finally gotten back to working on this website again, but most of my energy is dedicated to working on Asterisk related projects and
trying to find more time to write documentation.
