“The Spirit of Decentralization”

This is a very interesting read on the open web. One of the core ideas here is something that we think and talk about a lot, which is that social media and private networks are killing the open web that blogs played such a huge role in creating.

“Blogs gave form to that spirit of decentralization: They were windows into lives you’d rarely know much about; bridges that connected different lives to each other and thereby changed them. Blogs were cafes where people exchanged diverse ideas on any and every topic you could possibly be interested in.”

And this conclusion:

“New, different, and challenging ideas get suppressed by today’s social networks because their ranking strategies prioritize the popular and habitual.“

I’ve always believed that, given time, people will float back to the decentralized web.  Technology moves so quickly these days that I’m really not even convinced that internet providers, social networks, or congress can prevent the open sharing of information.

I gave up Facebook several months ago after reading a few studies about the negative impacts of Facebook on happiness.  I was concerned that my real friends would think I was shunning them or that I’d be out of the loop.  But none of those things have happened.  In the end, the only difference is that I’m spending those precious minutes online reading more blogs.  It’s inspiring and enriching and I’m grateful to have made the change.

Photographer Stephen Orlando Captures the Movement of Musicians Through Light Painting

by Kate Sierzputowski
Bach Cello Suite No. 1 Prelude

Bach Cello Suite No. 1 Prelude

Photographer Stephen Orlando (previously) captures the nearly imperceptible movement one makes when quickly sliding a bow along strings, the senses typically drawn to the sounds rather than appearance of the instrument being played. By using carefully placed LED lights and a long exposure Orlando can track these movements through space, following arms and bows with light trails that extend out from the body and instrument. These bright ghostly marks are captured through his photographic technique and not altered with Photoshop, making their distinct patterns all the more spectacular.

The Ontario-based artist was inspired by the lighting painter Gjon Mili, who also experimented with violins in 1952. Orlando explains:

A relative motion between the performer and camera must exist for the light trails to move through the frame. I found it easier to move the camera instead of the performer. The LEDs are programmed to change color to convey a sense of time. The progression of time is from left to right in the viola and violin photos and from top to bottom in the cello photos. Each photo is a single exposure and the light trails have not been manipulated in post processing.

You can see more of Orlando’s lit rainbow pieces on his Instagram and Facebook.

Palladium-Catalyzed Decarbonylative Dehydration for the Synthesis of α-Vinyl Carbonyl Compounds and Total Synthesis of (−)-Aspewentins A, B, and C

by Yiyang Liu, Scott C. Virgil, Robert H. Grubbs, Brian M. Stoltz

Abstract

The direct α-vinylation of carbonyl compounds to form a quaternary stereocenter is a challenging transformation. It was discovered that δ-oxocarboxylic acids can serve as masked vinyl compounds and be unveiled by palladium-catalyzed decarbonylative dehydration. The carboxylic acids are readily available through enantioselective acrylate addition or asymmetric allylic alkylation. A variety of α-vinyl quaternary carbonyl compounds are obtained in good yields, and an application in the first enantioselective total synthesis of (−)-aspewentins A, B, and C is demonstrated.

Vinyl unveiled: It is described that δ-oxocarboxylic acids can serve as masked vinyl compounds and be unveiled by Pd-catalyzed decarbonylative dehydration to enable the α-vinylation of carbonyl compounds to form a quaternary stereocenter. A variety of α-vinyl quaternary carbonyl compounds are obtained in good yields, and an application in the first enantioselective total synthesis of (−)-aspewentins A–C is demonstrated.

A 17th-Century Stanchi Painting Reveals the Rapid Change in Watermelons through Selective Breeding

watermelon-1

Old master work paintings are frequently cited for their depiction of historical events, documentation of culture, or portraiture of significant people, but there’s one lesser known use of some paintings for those with a keen eye: biology. One such instance is this Renaissance still life of various fruits on a table by Giovanni Stanchi painted sometime in the 1600s that shows a nearly unrecognizable watermelon before it was selectively bred for meatier red flesh.

Horticulture professor James Nienhuis at the University of Wisconsin tells Vox that he’s fascinated by old still life paintings that often contain the only documentation of various fruits and vegetables before we transformed them forever into something more desirable for human use. You can read a bit more about the science behind the changes in watermelons over the last 350 years here. (via Kottke)
