Daniel Janzen, Biologist

I have met very interesting people through Esther Dyson (on Wikipedia). The most recent such person is Dan Janzen as Esther encountered him at Science Foo Camp (on Wikipedia), hosted by O'Reilly and Google. Esther "captured" Dan in a most amazing photo.

Blog entries about Dr. Janzen
A group of Googlers (employees of Google) are studying how structured data can be used in a web search. In pursuit of this question, they spent some time with Dr. Janzen.

• Adam Sadovsky writes in his blog, Tmunot, about his travels with Dr. Janzen to the ACG in Costa Rica (includes photos).
• Alon Halevy writes about the trip in his blog entry, Bar Coding in Costa Rica. Alon also has 45 photos from this trip.
• In conjunction with this trip, there is a quick tour of the dormitory at the ACG (48 seconds) uploaded April 1, 2008. Googlers who went on the trip might want to see if they are in the video, "Controlled burn in the ACG" (1 minute, 44 seconds); the rest of us will be more interested in the description explaining why they were burning the field.

Keeping up with Technology News in Education

Twenty-five years ago, keeping up with technology news meant subscribing to the weekly InfoWorld. I have followed this magazine for that time period. I preferred it to more education oriented magazines.

I have added another magazine to my list to watch. It is electronically delivered and is called eSchool News out of Bethesda, Maryland. I really like the opening page where they have news stories categorized in a way that I can quickly check the news that I am really interested in.

I will add to this entry over the next few days.

Hanging pictures in my new apartment

As mentioned in a previous post, I moved in April. It is now the end of August and there are still pictures to hang. In general, I used nails or screws that were already in the wall to hang things, even when the location was not exactly what I would prefer. Except for the kitchen, the bathroom, and my office, the apartment has picture molding in the five other rooms. I was required to use clips to hang pictures on picture molding when I lived in the University of Houston dormitories some years ago. Remarkably, I still have two of those clips from college today. I have visited countless hardware stores in my area looking for similar picture hanging clips. There are generally two types of clips that the stores have had and neither work on my molding.

The Internet to the rescue! Since I spent a lot of time looking and reviewing, I have decided to make an entry here for my own reference. Perhaps others will also benefit. The picture molding is also referred to as picture rails, which is sometimes called Ogee or OG molding. What I have called clips are called picture hooks, picture molding hooks, picture rail hooks, and S-hooks. The rails and hooks were the preferred solution to decorating plaster and lath walls in the 1880's through the 1920's and into the 1930's. Yes, the house I now live in was probably built in the latter part of that time period.

In the realm of "how to" sites, the following are arranged from best to good:

• Picture Hang Solutions in North Carolina give the best instructions for picture rail hooks that I have found (scroll down to the bottom of the page for the instructions). The picture hanging hardware business is a spin off of their fine art gallery business. They recommend using stainless steel twisted cable instead of monofilament (fishing line), which stretches over time.
• Picture hanging instructions using picture rails shown in photos by The Swan Company featuring the backsides of frames so you can see how to attach cord or wire using various hardware. They also have an extensive photo gallery of ideas showing how their customers hung pictures.
• Martha Stewart on arranging pictures including the use of picture rails. She also shows an interesting way to hang multiple small pictures using a picture rail.
  
• Specialty Techniques for Historic Homes is a good place to "ask the expert," so I include it as a place to ask when all else fails. Here are a few existing Q&A's on picture rails: Picture rail molding with cornices, Using ribbons to hang pictures, Picture rail in 1920s homes, and Picture rail for curved walls.
• In Ask MetaFilter, the question was "How do I use picture rails?" This was the first such site I found and had good links. Here I found picture hooks exactly like the ones I have. For more discussion, here is an Ask MetaFilter search on picture rails.
  
• Historic Style has a period photo of pictures hung from picture rails and gives some historic information.

Here are the sites with noteworthy picture rail hooks (in random order):

• Wide Brass Picture Rail Hooks - 2 for $1.00. One and 5/8-inch long x 11/16-inch wide x 1/32-inch thick, which is the size I have. Scroll down to the bottom of the page for specifications and very detailed instructions for hanging pictures. [from Picture Hang Solutions in Hillsborough, NC]
  
• 1/2 inch Simple Rail Hooks - 10 for $2.50. See also their selection. My picture hooks from college are 11/16 inch wide. [from Rejuvenation in Portland, Oregon and Seattle, Washington]
  
• Moore Push Pin has zinc molding hooks with two holes in them so one might use a nail to reinforce the strength of the hook (scroll down about three-fourths of the way to see the item). I don't like that they are made of zinc, but the holes are intriguing. They come 3 on a card for $1.97 and are suitable for weight up to 15 pounds. I am keeping this item as it referenced the weight that can be supported (with nail holes!). [from Office1000.com in Oil City, PA]
  
• Secure brass-plated picture hooks - 2 for $1.50. These also have the holes for nails. They are one and 3/4 inch long by 1/2 inch wide x 1/32-inch thick. They also come in a nickel-plated version of the same size. The secure picture hooks are recommended in areas where there are earthquakes. [from Picture Hang Solutions in Hillsborough, NC]
  
• Molding hook by Hillman Fastner Corp. - 10 for $22.90; only sold in sets of 10. I include this link because many of the hardware stores I visited had other hooks by Hillman, but not this one. This hook has one nail hole in it. By the way, Hector's Hardware Store [Williamsville, NY] has the same item that must be purchased in sets of 10 for $19.90. Neither Do-It-Best [Fort Wayne, Indiana] nor Hector's give any additional information about the size of the hook.
• Victorian Picture Molding Hook - 1 for $6.72. It is 1.5-inch high x 1.75-inch wide, solid brass. I include this one because it is beautiful and vintage. [from Paxton Antique Cabinet & Lamp Hardware, LTD in Maryland]
  
• Antique Picture Molding Hook - 1 for $2.99; solid brass. One and 3/8-inch high x 1-3/8 inch wide by 1-3/8-inch deep. [from Antique Hardware & Home in South Dakota]
  
• Jane Austin Collection - they seem to be selling the cord that hangs the pictures on the picture molding hook. While other sources recommend hanging pictures using at least two hooks, this page shows a way to hang a picture using only one hook. I include it for its history. [from The Swan Company in Orland, CA]
  
• Picture Molding Hook in choice of 8 finishes - 1 for $.80; 1.75-inch tall x .5-inch wide x .04-inch thick. [from Golden's Antique Supply in Woodstock, GA]
  
• House of Antique Hardware's (Portland, Oregon) selection of picture molding hooks - prices range from $.59 to $2.99 each. House of Antique Hardware also has the hooks that look like mine (brass is the same size as mine) in plain styles in steel with 8 finishes ($.79 to $1.29; 1.75 inch tall by 1.5 inch wide by .04 inch thick) and in solid brass in 8 finishes ($1.99 to $2.09; 1.75 inch tall by 11/16 wide by .05 inch thick). They also offer a selection of picture hanging cord.
• Various Victorian molding hooks - prices range from $1.50 to $8.95 with cord in 4 colors ($1.30) and Victorian tassels ($19.00). [from Crown City Hardware in Pasadena, CA]

I was planning to use monofilament to hang my pictures, but will switch to wire or cord. The violinist I bought in Paris weighs between 12 and 13 pounds, so I could probably use a cream or gold colored cord as the picture lends itself to antiquity. It will go in my living room with one wall inspired by Maurice Sendak's Where the Wild Things Are (Google Books, Wikipedia, Amazon). In my searching for picture hooks, I discovered that someone else did a wall inspired by this book (OK, the site that led me here was the Adirondack Boys blog). I will add a photo of the violinist picture hanging in my livingroom as soon as I get it completed.
