11/18/2008 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 ...
11/18/2008 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 ...

11/18/2008 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 ...
11/18/2008 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 ...
11/18/2008 Only writing complex dialplan statements once
So for a few years I've had this idea that was originally hashed out with Olle Johanson back in the day when we did Asterisk trainings together. We thought why not have a declared extension, reserved much like s, n, i, t, T, etc... extensions are reserved for special uses. ...
11/18/2008 Getting ready for testing
I have have found an issue on the Asterisk bug tracker that is marked ready for testing. There is a patch available, but I don't know how to get Asterisk running to test the issue. This is a quick guide for how to do it.

11/18/2008 Tattoo featured on O’Reilly :)
Last week I got an email from Laurel Rumo (production editor on the 2nd edition of Asterisk: The Future of Telephony) where she just saw my tattoo for the first time after following me on twitter. She asked if my tattoo was real, of which I replied that it was ...
11/18/2008 New Business Logo!

Now, just need ...
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. Also be sure to find me in the Code Zone! where I will be working on a lot of documentation and clustering solutions!
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.
