Raspberry C64 Pi Computer

Running A Raspberry Pi 4 in a C64 case with fully functional keyboard and USB hub.

I integrated a Raspberry Pi 4 into a Commodore C64 Maxi case. The Pi uses the integrated keyboard and the USB hub. An integrated power supply provides power to both, the Pi and the C64, which now run in parallel. The Raspberry Pi boots from an internal SSD drive, turning this machine into a full desktop computer that can also run Retro Pi for true retro gaming.

New Podcast Episode: The Rise And Fall of ATR

My new podcast episode is available.

My new podcast epidote of the Human-Robot Interaction Podcast is now available. The Rise And Fall Of ATR explores the history of The Advanced Telecommunications Institute International in Japan. I interview Takayuki KandaMichita Imai and Dylan F. Glas about their work at ATR and their lives afterwards.

New Episode of the HRI Podcast available.

New HRI Podcast episode about ATR is available.

The new HRI Podcast episode entitled “Humans and/or Robots at ATR” is now available. Here is the abstract:

The Advance Telecommunication Research Institute International in Japan is a major contributor to Human-Robot Interaction. I interview Takayuki KandaMichita Imai and Dylan F. Glas about their work on robots at ATR. How was Robovie developed and what is the goal of the Erika android? In two episodes we will have a closer look at the people working at ATR and the robots they created. We will also discuss what it means to work for a research lab like ATR in Japan.

The Design History of Robert M. Pirsig’s Books

I published my article on the history of Robert Pirsig’s books at the Humanities Commons.

I admire Rober Pirsig’s work on the Metaphysics of Quality as described in his two books Zen and the Art of Motorcycle Maintenance and Lila. Robert passed away in 2017 I started to collect all the English editions of his books. I wrote an article entitle “The Design History of Robert M. Pirsig’s Books” in which I analysed all these books and their covers. The book proposal for Zen was rejected by 122 publishers. My article was rejected by only nine journals but this was done sequentially, which took almost a year. It seems like Pirsig’s curse is upon this manuscript. Academic publishing remains difficult and I recently interviewed Anton Angelo about it.

It is time to take a new approach and hence I decided to publish the article in the Humanities Commons. Please enjoy the article. High resolution scans of all the book covers are available over at the Open Science Framework. I also published the scans of all the covers over at Flickr. Have a look at the Zen and Lila albums.

How religious is Christchurch?

While driving around Christchurch I noticed a church on almost every corner. The name of the city could have already given me that hint, but it is better to check the facts first before jumping to conclusions. Christchurch was named after the Christ Church College at Oxford University.

There does not seem to be any register for churches in New Zealand and hence I searched the Charities Register for charities that provide religious services. The results contain more than 7000 charities, but many of them are no longer registered and/or have stopped operation. After some cleaning of the data I was left with 5590 records for New Zealand. It is important to note that not every religious charity is a church and not all churches are registered as a charity. One charity could also operate several churches. But for what it is worth, this approach does seem like a good approximation. The various Anglican parishes, for example, are listed individually.

Mapping these religious charities on a map would be slightly misleading since bigger cities will naturally have a higher number of charities. To create a density map of the religious charities in New Zealand I had to take the population distribution into account.

InfoShare from StatsNZ allows you to download the download the Estimated Resident Population for Urban Areas. It contains population estimates for many of New Zealand’s cities. Unfortunately, this list does not contain all the small cities, such as Akaroa.

After cross referencing the charities with the population information I created this density map of religious charities in New Zealand. Christchurch has 517 registered religious charities and a population of 404,600 in 2018 which results in 0.0012 people per charity. This puts Christchurch in the lower half.
