I just discovered that in my neighborhood is a business called Well Beings Veterinary Homeopathy. People in the city do treat their pets like people, and belief in homeopathy is consistent with stereotypes of Californians, but what really tickled me was to see the “well” prefix (usually as in “well-woman” or “well-baby”) added to the somewhat Buddhist use of the word “being”. This name sounds like a parody created by someone mocking San Francisco.

(Homeopathy is an alternative medicine, which treats diseases with ultra-pure water.)

In digging deeper, I found this was not an aberration, that there are practitioners of veterinary homeopathy in many parts of North America. One disturbing thing I found was in a question-and-answer page on the web site of the person responsible for training many of these practitioners:

Q 12. If you are treating an animal with homeopathy and they need dentistry (perhaps teeth removed), or are thought to have Lyme disease, or develop an infection or abscess, would you then change over to using antibiotics and other allopathic treatments?

There are many veterinarians that offer homeopathy that do not really rely on it when “times get tough”, when there is what appears to be an infection or severe inflammatory condition. This, of course, is their professional opinion but going back and forth between homeopathy and the usual use of drugs does not really work well and is not the most skillful approach. You may not have choice in this regard but if you do, especially with animals having a chronic condition, try to find a veterinarian that firmly believes in and uses homeopathy even in what appears to be serious illness.

(The term “allopathic” is a term used by homeopathic proponents to describe standard medicine.)

For human beings, we might expect some benefit from homeopathy just because of the placebo effect. However for non-human beings, presumably homeopathy will have absolutely no effect because they will not have a placebo response.

I hope there are not too many animals that suffer unnecessarily as a result of being given pure water instead of real veterinary care.

Challenging Dogma, originally uploaded by andrewrosspoetry.

I somehow got sucked into a rather exhausting debate on evolution with creationist Andrew Ross in the comment section of one of his photographs on Flickr.

Thanks to all the beta testers of the 0.2 release for your testing and reviews.

A much improved 0.3 version is now ready for installation from the Palm application web page.

Changes in 0.3:

  1. Display the photo title, which is also a hyperlink to the Flick photo page.

  2. Improve algorithm for selecting photographs to include closeness as well as interestingness, and to automatically adjust the radius of search depending on the density of nearby photos.

  3. Display a status message when communicating with Flickr so when you have a slow network connection you can tell what is happening.

  4. Display some dummy photos in case you have no network connection or if there are no photos within 32 km.

  5. Use photos to which I have copyright (my own) as the example photos and dummy photos.

  6. Fixed some bugs encountered when flicking through photos.

  7. Fixed some bugs accessing Flickr.

Please add any comments or questions below.

(Update: There is now an later release)


Displays photographs that people on the Flickr have taken close to your current location. Flick left and right to browse through the photographs. Automatically updates as you move. (All photographs are copyright of their owners.)

You can install the beta release from the Palm application web page.

This is a personal open-source project. The code is on GitHub.

(Update: there is now a new improved release.)


The meme of Christianity was in decline on the Western fringe of Europe as the Germanic tribes of the Angles and Saxons and Franks swept aside the lingering Celtic-Roman society left behind by the Roman Empire. But, some carriers of the meme, personified in legend as St Patrick, made it to Ireland where it proved stronger than the pre-existing polytheistic Druidism, and from its Atlantic fastness it ultimately spread back East and Christianized the invading Germanics. I celebrate this today not so much because of the Christianity but because of the technology of Writing that accompanied it, setting Ireland on a literary course that ultimately lead to Yeats and Joyce and Becket and Heaney. Happy St. Patrick's Day!

I like the Pimsleur courses a lot. They allow you to get to a very basic speaking level in a language very quickly.

The courses are audio-only — in fact, they expressly discourage you from reading the language while you are listening to the course.

Nevertheless, now that I am finished the first eight lessons I feel the need to actually see what the written Chinese (both pinyin and characters) looks like. So here is the vocabulary from Pimseur Quick and Simple Chinese Mandarin, Lesson 1. I show both the standard pinyin and in my own phonetic impression of how the words sound.

The iText library is a great resource for generating and manipulating PDF files. However its API is very complex and there is a notable lack of good online tutorial material. So you often must resort to plowing through the Javadoc-generated API documentation trying to figure out how to use the library.

Doing that, you might be annoyed at the fact that the API available online does not just include the public and protected members, but also includes package-private and private members. While this would be useful to people working on the internals of iText, it is just a lot of useless clutter to most people who are just going to use the API.

So I regenerated the Javadoc from the 5.0.1 source, using the default settings which hides the private stuff. You can access this at:

I have seen several reverences to Airnergy device by RCA that claims to recharge a battery by harvesting WiFi signals from the air.

That sounded a bit fishy to me. Let's look at some numbers. First, how much power does a WiFi hotspot put out? According to moonblinkwifi.com a typical output is 200 mW.

Now say this device is 3 metres (10 feet) away from the hotspot. This 200 mW of power will be spread on the surface of a 3 metre-radius sphere with a surface area of about 110 square metres.

Now, this device looks to be about 10cm X 5cm which is about 1/22000 of the area of the sphere across which the 200 mW is spread. Which means the amount of power hitting the device is about 9.1 μW

Now according to the Wikipedia battery article a small AAA rechargeable battery stores about 6700 J of energy. How long would it take to recharge a AAA battery with our 9.1 μW of power, assuming you could miraculously capture 100% of the power?

The answer: 24 years.

OK, there are some approximations here. The WiFi antenna does not actually broadcast equally in all directions, and you might have the device closer to the antenna, and there might be multiple WiFi signals you could receive. On the other hand, you probably want to recharge a battery that has more capacity than a little AAA battery.

So I call bullshit. A battery charger that takes on the order of a decade to recharge a battery, is a useless device.

The sad thing is how many tech journalist sites reported uncritically on the Airnergy.
