Mapping the Cloud in ‘Immaterials: Light Painting WiFi’

the article
: In this video, eerie long-exposure photographs reveal the
invisible wifi networks that permeate our urban environments, making the cloud
available everywhere. …In order to study the spatial and material qualities of
wireless networks, we built a WiFi measuring rod that visualises WiFi signal
strength as a bar of lights. When moved through space the rod displays changes
in the WiFi signal. Long-exposure photographs of the moving rod reveal cross
sections of a network’s signal strength.]

A Different Kind of Secret Code

the article
: Researchers have invented a new form of secret messaging using
bacteria that make glowing proteins only under certain conditions. In addition
to being useful to spies, the new technique could also allow companies to
encode secret identifiers into crops, seeds, or other living commodities. The
new glowing bacteria actually did grow out of a bit of cloak-and-dagger
thinking. Several years ago, the Defense Advanced Research Projects Agency
asked researchers to submit ideas for ways to encode secret messages without
the need for electronics. At the time David Walt, a chemist at Tufts University
in Medford, Massachusetts, teamed up with his former adviser George Whitesides,
a chemist at Harvard University. Together, they came up with a way to add a
variety of metal salts to a fuse that, when lit, would give off a sequence of
pulses of infrared light that encoded a message. That got them thinking about
other ways to accomplish the same thing. And so last year they decided to try
something else, using bacteria to encode their secrets.]

UC San Diego Gets Big Picture with ‘OptIPortable’ Video Walls

[From the article: “The new Vroom video wall has enabled our
researchers and their students to take their collaboration capability to a new
level and has challenged them to explore new areas of information technology
with a completely immersive mixed media environment,” said Thomas DeFanti,
director of visualization for Calit2.

which brings together technology research with a focus on applications, refers
to these wall-sized visualization facilities or clusters as
“OptIPortables.” First installed in March 2010 at UCSD using 32 NEC X462UN displays
and then elsewhere at its partner institutions around the world, the Institute
uses the video walls to allow simultaneous video conferencing and visualization
of large-sized data sets. …According to DeFanti, NEC displays have been used
because “they consistently offered the narrowest bezels we could purchase
at the time, a critical issue for viewing super-high-resolution imagery.”
Also, he added, NEC has displays in the sizes the Institute needs. More
recently, the display shopping list has added the requirements of LED
backlighting and 2D and 3D collaboration capabilities.]

Gets Big Picture with ‘OptIPortable’ Video Walls

The University of California,
San Diego (UCSD) has decided that more and bigger is better, especially for
immersive experiences. The university is building out its collection of virtual
rooms that use multiple large-screens for visualization.

Princeton bans academics from handing all copyright to journal publishers

bans academics from handing all copyright to journal publishers

Sunanda Creagh, The Conversation, September 28, 2011.


US academic institution Princeton University has banned researchers from giving
the copyright of scholarly articles to journal publishers, except in certain
cases where a waiver may be granted. The new rule is part of an Open Access
policy aimed at broadening the reach of their scholarly work and encouraging
publishers to adjust standard contracts that commonly require exclusive
copyright as a condition of publication.”
