Yale makes available online 170,000 photographs from WWII period

History: Yale University had posted online 170,000 Library of Congress photographs taken in the United States from 1935 to 1945.

The photos come from all over the U.S., and can be accessed with this easy-to-use inactive map. They also used the original captions, thus avoiding any editing for politically correct reasons and allowing the viewer to get an honest feel for the time period.

Market Street, San Francisco, April 14, 1906

An evening pause: This film footage has been circulating about on the web for several years. I even think I posted it previously but can’t find that post now. Either way, it was shot mere days before the San Francisco earthquake, and provides us a window into the reality of life then. The sound effects add to the reality, though they are not original to the time. They were added later and were dubbed in with what I think was great care. See the notes here for more details.

For the first time a giant squid has been filmed in its natural habitat.

For the first time a giant squid has been filmed in its natural habitat.

In hopes of drawing the animals in, [Edith] Widder [of the Ocean Research and Conservation Association] used a different sort of light. Although very little sunlight penetrates to the deep sea, many deep dwellers produce a bioluminescent light. Past research by Widder suggests that the bioluminescence can act as a sort of burglar alarm, among other functions. The idea is that the bioluminescence produced by some prey when they are attacked may serve to attract larger predators — such a giant squid — that will then eat the attacker.

Widder and her colleagues therefore fitted Medusa with an electronic device that mimicked the bioluminescence that jellyfish produce when attacked to serve as a lure. It worked: Medusa first encountered a squid during its second deployment, igniting jubilation on the ship. “I just was blown away,” says Widder,” I couldn’t have been happier.”

Facebook’s Instagram has updated its terms and conditions so that it now claims “perpetual” ownership to all photographs posted by users.

Facebook’s Instagram has updated its terms and conditions in order to claim “perpetual” ownership to all photographs posted by users.

“You acknowledge that we may not always identify paid services, sponsored content, or commercial communications as such,” the new terms say. That may let advertisers use teenagers’ photos for marketing, raising privacy and security concerns, Jeffrey Chester, executive director for the Center for Digital Democracy, told Bloomberg.

And people wonder why I am not on Facebook.
