CAM remedies can give you heavy metal poisoning

A comment over at Respectful Insolence led me to this post by Mike O’Risal and the Associated Press article that inspired it.

The AP article reports that:

Health departments around the country say traditional medicines used by many immigrants from Latin America, India and other parts of Asia are the second most common source of lead poisoning in the U.S. — surpassed only by lead paint — and may account for tens of thousands of such cases among children each year.

Dozens of adults and children have become gravely ill or died after taking lead-laden medicine over the past eight years, according to federal and local health officials.

Read the whole article for the details and remember, there are good reasons why the life expectancy of people is significantly higher in places that use modern, regulated, evidence based medicine.

Martin Luther King Day

Today we honor one of the greatest men of the 20th century, the Reverend Dr. Martin Luther King Jr. I feel the best way to celebrate this day is to read some of his writings and listen to some of his speeches. Visit The Martin Luther King, Jr., Research and Education Institute to read some papers or see my previous post with selected quotes from the King papers, MLK Jr., Science, Darwin & Intelligent Design. GrrlScientist has posted two excellent MLK videos in honor of this holiday.

Happy Birthday James Watt

James Watt was born on this day, January 19th, in 1736 at Greenock, Scotland. He was a mechanical engineer and inventor who’s steam engine was a key ingredient in the start of the Industrial Revolution. For this and his other contributions to science and technology the SI unit for power was named the watt in 1960. For more information check out the biographical reference links below. I think I’ll celebrate his birthday buy having a piece of PIE (sorry couldn’t resist the bad EE geek joke).

Embarrassing Engineers the next generation

This report in the Michigan Daily highlights one of the next generation of illogical and irrational engineers. The article starts out with this gem.

Engineering senior Israel Vicars didn’t think it was a coincidence when he walked by a drunken girl who had fallen over in a parking lot and desperately needed help.
Vicars attributes his ability to safely return the girl to her residence hall to the power of united prayer.

OK so did the praying levitate the girl and allow him to lightly push the girl back to her home. If that happened then there’s be a million dollar prize waiting for Israel Vicars if he can demonstrate the effect. Prayer sometimes has a good effect on the psychological state of some people whom practice it. However, no prayer has ever been shown to do anything in the physical world. Instead people like this guy use confirmation bias to claim that something wasn’t a coincidence or random chance it was their prayers that did it.

With sloppy thinking like this I shudder to think how this guy is going to handle real world engineering problems. I sincerely hope Israel Vicars doesn’t work on engineering projects that will waste my tax dollars or lead to safety problems due to his magical thinking.

Absolute Zero

I just finished watching part one of the NOVA episode “Absolute Zero” on PBS last week. Check your local listings to see if you can catch it on a re-broadcast or you can watch the program online. Part two will broadcast on most stations on Tuesday the 15th and will be online on the 16th.

Generally I found the program exceptionally good, it covers the history of scientific thinking about hot and cold very well as well as showing the commercial uses. I have only two criticisms and they are so small they are really nitpicking. The first is that the narrator as well as Professor Hasok Chang, author of “Inventing Temperature, Measurement and Scientific Progress”, both use the obsolete units name centigrade. It probably just bugs me because I can still remember losing grade points in Mrs. Wolfs’ chemistry class for using centigrade instead of Celsius. The other criticism is the lack of clarity when in the part on Clarence Birdseye the narrator says, “temperature forty degrees below freezing”. I had to pause the playback and think for a minute wether they meant Celsius or Fahrenheit. My first thought was that they meant -40°C which equals -40°F but then I remembered that household freezers are around 0°F so, I think they meant -8°F (-22°C).

I encourage everyone to watch this fine program and please support your local PBS station so, they can keep bringing us the best science show evah, NOVA.

Netscape Navigator is going away

According to the Netscape Blog, on February 1st support for Netscape Navigator ends. I switched my primary browser from Mosaic to Netscape in 1995 and used it almost exclusively up until Internet Explorer 5.0’s release in 1999. Although I have rarely used any of the Netscape versions since Phoenix (1st version of Firefox) came out in 2002, I still think it’s a bit sad that the Granddad of the Mozilla/Firefox/SeaMonkey lineage is gone.

FCC wants to make Do Not Call list permanent

Conformity Magazine pointed me to this December 4th notice from the FCC. The commission would like to eliminate the automatic expiration for the Do Not Call registry. I think every US citizen who is not employed in the telemarketing industry would like this rule change to go through.

The statement of Chairman Kevin J. Martin sums up the commission’s decision:

Today’s action tentatively concludes that telephone numbers registered in the National Do-Not- Call Registry will not expire after 5 years. The Commission continues to move forward to protect consumers who have registered their telephone numbers on the Do-Not-Call list. Consumers expect their telephone numbers to remain protected under the Do-Not-Call list until they have cancelled their registration or their telephone number is disconnected or reassigned.

Instant Media is dead, long live Miro

My regular reader 😉 may remember that I’ve recommended Instant Media (I’M) as an alternative to Joost in previous posts. Over the last 6 months or so I basically only used it for automatic downloading of DL.TV and Cranky Geeks (linked under Netcasts on the right). While I had noticed that the I’M guide wasn’t working back in September I hadn’t bothered to find out why. This week I looked around and found some information in these blog posts.

Instant Media Gone Bust? Feeling the Web Video Bubble Burst

Instant Media, Miro Competitor, Leaves The Net Without A Trace

Instant Media Grinds to a Halt

Those posts speculate on what happened and the last one linked above does have a fairly definitive answer from one the the former developers.

Scott Blum, the eccentric billionaire that was funding our company, decided to scuttle it mid-July

This was a little puzzling, why did the I’M web site stay online until September when the plug had been pulled in July. This blog post gives me an idea of why, the company tried to sue Microsoft and get a preliminary injunction over Microsoft’s use of their trademark, I’M. That seems like the reason to me, I’M had to stay up on the web until the court decided, once the courts ruled against I’M in the middle of August I’M had no further incentive to stay around.

Since I’M was gone I decided to look around for an alternative and I found a great one, Miro. This is an excellent program especially since it’s open source and cross platform. I installed it on my OpenSuse 10.3 PC and setup a Samba share so that my Media Center PC can play the videos. One feature I hope to make good use of once NerdTV starts season two is Miro’s support for Bittorrent. I like the idea of be able to easily to give some of my bandwidth to NerdTV to help defray the distribution costs (PBS doesn’t have very deep pockets).

Processing my digital photos part 1

Over the past month I’ve been revising the work flow for handling my digital photos. With the purchase of my first digital camera back in 2000 I soon realized the need to develop a methodology that kept my photos safe while being easy to find and backup. Keeping the flow simple was important to ensure that I would keep using it for years to come without needing major revisions.

Although I’ve been trying for forty years now, I have never become a really good photographer. The advent of digital photography and scanning of old film and slides to digital formats has been a lifesaver. I can, and usually need to, retouch my photos without spending hours per image in the darkroom. With the easy retouch capability of today it is all too tempting to simply fix the original photos and just save it. This is tempting for its simplicity but my experience has shown that with any original data I regret this choice later on. Once you have overwritten original data you can’t go back so, for all types of digital data I enforce a policy on myself of only modifying copies never the original.

The next consideration is the compression used in many digital image file formats. It is not uncommon for me to go through many retouch iterations before I am satisfied with the result. Being all too familiar with the way PC’s tend to crash at the worst possible time, I like to save my work frequently while working on images. To prevent the loss of image quality I prefer to use a loss-less file format for images while editing and then export to JPEG after I’m finished.

These considerations led me to setting up the first part of my workflow back in 2000. When I add images to my collection, I start by creating a subdirectory under my main image directory. This directory is named with the original date of the images using a year-month-day format of YYYY-MM-DD. I then create two subdirectories below the dated directory, one named Originals and the other named JPEG. The directory structure looks like this:

D:My Pictures
              2007-12-25
                          JPEG
                          Originals
              2008-01-08
                          JPEG
                          Originals

Now I copy the images to the Originals directory and set the files to read-only using normal file management tools. By setting the file attribute most programs will automatically prohibit overwriting the original image. The few programs I regularly use that will overwrite read-only files at least give a warning message when I attempt to overwrite the file.

That’s just about all I want to write up for part one of this series of posts. The final thing to cover is how I’ve automated the directory creation process. It only took a few weeks of using this procedure back in 2000 until I tired of manually creating directories. First I created a simple batch file but it was a messy solution so I whipped up a simple VB application. The app prompted for the date name with the current date preset but editable. Then simply clicking OK created the date named directory and the two subdirectories underneath it. I used that app for many years until I started using the open source, GPL licensed, AutoHotkey scripting language.

Here’s my current directory creating script:
