Marking time on technology
Keeping up appearances
My old push bike has started to look daggy parked outside the polished granite foyers of city offices. It rides well, but the frame is rusty and the back tyre is balding. Time for a makeover and spoke-polishing.

Timber and iron in the smart colony
Yesterday I gave a talk at the Queensland Museum, part of a series called Queensland Connections series. In this series, speakers about cultural heritage subjects are teamed with Queensland Museum staffers who talk about natural environment subjects. The result is short talks and odd double-bills.

Researchers at Rochester Institute of Technology have been studying Georges Seurat’s A Sunday on La Grande Jatte - 1884. Their research paper describes their work — here’s the abstract:
George Seurat first employed his divisionist painting technique on A Sunday on L Grande Jatte - 1884 beginning in October 1885. Painting with pigments representing colors seen in the visible spectrum that were minimally mixed on the palette and using divided brushstrokes, he aimed to impart luminosity to the surface and to explore 19th century ideas of color theory, such as simultaneous contrast. Pigment analysis has disclosed that the brushwork containing zinc yellow has darkened significantly: Yellow, green-yellow, and orange brushstrokes have become brown, olive-green, and reddish brown, respectively. Additionally, the painting has further darkened due to the natural aging of the oil medium. By performing spectral reflectance measurements in-situ on darkened areas of the painting and on paint-outs of comparable unaltered colors, using Kubelka-Munk turbid media theory, imaging the painting with colormanaged digital photography, and image editing with Adobe® Photoshop®, a digital version of the original, more luminous appearance of La Grande Jatte was simulated.»more»

Discussion of the ingredients of cutler’s resin continued on the oldtools list today. Steven Longley has turned up an American supplier of pine resin, also called brewer’s pitch. You can buy it from Jas Townsend & Son, Inc.
Daniel E L Yurwit added this to the exchange:
FWIW, the Apache also made jugs woven from plant fiber (a “tuss”) to carry water, and coated them heavily with pine tar resin to waterproof them. Some still work effectively 100+ years later.»more»
Cutler’s resin
Pardon me, as I jot down a recipe. Cutler’s resin is 8 oz pine pitch, 1/4 cup carnauba wax and 4 oz of beeswax, melted together in a double boiler and used hot. Mark Marsay wrote on the oldtools mailing list:

From a mailing list message from an American soldier in Afghanistan:
Technology has changed the way we do business in the military. It does seem somewhat bizarre to have unfettered internet access in the middle of nowhere. I can sit in my tent with my ThinkPad and email, IM, and browse the internet the same as if I was sitting in my living room back in Georgia. Myself and 39 other buddies purchased a satellite system from an outfit out of India. The ISP is actually in Germany and we get just about T1 bandwidth which is split up 40 ways if everyone is one (which doesn’t occur due to different work shifts). We “beam” it out via Wi-Fi to the different tents. Even our aircraft (I’m in a CH-47 Chinook unit) are on an intranet of sorts. The system called Blue Force Tracker allows secure tracking of all the different aircraft (and ground elements) within the theater real time. We can email between aircraft and to our headquarters during flight…all with satellite technology. I’ve hardly sent a snail mail letter since I’ve been here.

The computer in front of me is my ninth. Its predecessors averaged less than two years on my desk. The superseded computers have trickled down to other people, then been sold or given away. When last seen, all of them worked well but couldn’t manage the latest software — practical proof of Parkinson’s law of data. Here’s the list of PCs and where I last saw them:

More online exhibitions: The Science Museum puts neat little exhiblets on its website. Like Blockmaking, eight pages about machines from the Royal Navy block factory, set up in 1805. The factory pioneered mechanised production of large numbers of identical widgets. Lots of blocks (which sailors never call pulleys) were needed on sailing ships — the exhiblet tells us that a seventy-four gun ship needs 922 of them. So the ship’s block was a good candidate for factory production.

Briarpress.org has a delicious online museum. Dozens of virtual printing presses are here, richly linked and organised, displayed with other tools of the trade. And there is an illustrated glossary of letterpress terms — handy if you don’t know your frisket from your tympan. I admire the clarity of words, pictures and navigation. My congratulations to Eric Nevin and the other authors.

The Morse Telegraph Club is a group of enthusiasts interested in any topic concerned with Morse code and telegraphy. Probably the biggest constituency in the club is retired landline Morse operators. Each year, the various chapters around the country meet on Professor Morse’s birthday to remember the good old days of landline telegraphy and the heyday of the railroads. In addition, keys and sounders are dusted off and telegraph circuits are established with other chapters around the country. Morse code is soon heard clicking from sounders and greetings are received from friends in other chapters.
