Hi! I’m Wolf Paulus. I’m a photographer, hiker, hacker, technologist, based in Ramona, California.
This is my journal, where I share quick thoughts and ideas on technology.

My photography portfolio can be found at https://wolfpaulus.photography


I’m appointed to the advisory committee at the University of California, Irvine, and occasionally speak at conferences and user groups on topics ranging from Embedded Technology to Emotional Prosody, and everything Voice and Conversational User Interface related.

Take a look at some slides from my most recent talks.


January 30-31, 2017 Conversational Interaction Conference


The CI Conference taking place at The Westin in San Jose, will discuss interaction with digital devices and applications by text or speech in natural language.
On January 30, I will be speaking at the conference on creating effective Conversational User Interfaces.

April 24-26, 2017 SpeechTEK


SpeechTEK 2017 is taking place in Washington DC and discussing “Speech as the Innovative Interface”. On April 24, I will be speaking at the conference on “The Conversational User Interface is a Minefield”


Many of the new concepts that I implementing, are communicated best through video clips or short films.

Take a look at some high quality short HD films that I have created over the last few months and years.


“Amateur Professionalism”, a concept used since 2004, describes an emerging sociological and economic trend of people pursuing amateur activities to professional standards. That pretty much describes how I look at my photography work today.

Installing Tomcat 8.5 on macOS 10.12 Sierra

The Servlet 4.0 specification is out and Tomcat 9.0.x will support it. However, at this point Tomcat 8.5.x is the best Tomcat version and it is supporting the 3.1 Servlet Spec.

Since OS X 10.7 Java is not (pre-)installed anymore, let’s fix that first.

The Conversational User Interface is a Minefield

The path to an acceptable Conversational User Interface is heavily mined and booby-trapped. Let’s not fall into the IVR trap, but create a humanized and personalized user experience. [IVR – Interactive voice response is a technology that allows a computer to interact with humans through the use of voice and DTMF tones input via keypad. – Think about calling your insurance company … ‘To file a claim, press 2’]

While they can benefit greatly from each other, there is no need to create a dependency between a Conversational User Interface (CUI) and Machine Learning (ML). It is not hard to imagine how a CUI can be put to good use with a currently existing service infrastructure. In fact, I think it is a good idea to apply the principal of “separation of concerns” and not merge the already difficult task of creating a CUI with new or untested ideas for services and solutions. read more…
