"GNU SIP Witch can be used to build secure and intercept-free telephone systems that can operate over the public Internet."

The SIP Protocol

To make all that possible, GNU Free Call will use the Session Initiation Protocol (SIP), an Application Layer signaling protocol that's designed to be independent of the underlying transport layer.

Specifically, it will build upon the existing GNU SIP Witch VoIP server, which operates without introducing a central point through which communications can be intercepted or captured. GNU SIP Witch also requires minimal system resources, making it suitable even for low-end embedded routers.

GNU SIP Witch is already packaged in a number of popular Linux distributions, including Ubuntu and Fedora, but it can also be built on most BSD systems from source, and it supports compilation on Microsoft Windows as well, according to the GNU Free Call project.

"We will extend SIP Witch to become aware of peer nodes by supporting host caches, and then support publishing of routes to connected peers," the project explains. Host caches are a mechanism used in older P2P networks and are easy to implement, it adds.

Synthetic Biology Open Language

http://www.sbolstandard.org/docs/turtle-rdf-primer-for-sbol

Turtle is a text RDF representation, it’s based on N3. This form of RDF is easier for people to read and write than RDF/XML. This primer provides a guide as to how to write SBOL as RDF in Turtle syntax.

To: DIYbio <diybio@googlegroups.com>


Jonathan Eisen at UC Davis is heading a new project called the
"Microbiology of the Built Environment Network". Jonathan is a big
proponent of Open Access and citizen science, and he has been posting
some ideas for projects that would lend themselves very well to a
DIYBio approach, including sampling microbes from water heaters,
aquariums, etc. Check 'em out:

I'm trying to play matchmaker between Jonathan and our new BioCurious
lab in the Bay Area - it'd be great to do something together.

The Known Universe takes viewers from the Himalayas through our atmosphere and the inky black of space to the afterglow of the Big Bang.

The Known Universe takes viewers from the Himalayas through our atmosphere and the inky black of space to the afterglow of the Big Bang. Every star, planet, and quasar seen in the film is possible because of the world’s most complete four-dimensional map of the universe, the Digital Universe Atlas that is maintained and updated by astrophysicists at the American Museum of Natural History. The new film, created by the Museum, is part of an exhibition, Visions of the Cosmos: From the Milky Ocean to an Evolving Universe, at the Rubin Museum of Art in Manhattan through May 2010.

Packmol creates an initial point for molecular dynamics simulations by packing molecules in defined regions of space. The packing guarantees that short range repulsive interactions do not disrupt the simulations.

Packmol creates an initial point for molecular dynamics simulations by packing molecules in defined regions of space. The packing guarantees that short range repulsive interactions do not disrupt the simulations.

The great variety of types of spatial constraints that can be attributed to the molecules, or atoms within the molecules, makes it easy to create ordered systems, such as lamellar, spherical or tubular lipid layers.

The user must provide only the coordinates of one molecule of each type, the number of molecules of each type and the spatial constraints that each type of molecule must satisfy.

The package is compatible with input files of PDB, TINKER, XYZ and MOLDY formats.
