Linked Data. Alexandre Passant. About 2 years ago, we designed SMOB, a Semantic Microblogging client and server application, in order to demonstrate how Semantic Web and vocabularies like FOAF and SIOC could be used to provide a more open microblogging experience. While we did not improve is much since then, there have been a lot of work on it these last months (about 250 SVN commits since end of October, when we decided to revive it) and I’m happy to announce that SMOB v2.0 is now officilay out, after some internal beta-testing during the last weeks. Overall, it has been a complete code rewriting and architecture redesign since the previous release. While the initial version relied on clients and servers to respectively publish and aggregate data, this new version is based on the concept of distributed and independent hubs that communicate each other to exchange data, being microblog posts as well as followers / following lists.

We should have referred to John Snow as a doctor, not a professor. RDF. Web 3.0. Carbon nanotubes used to make batteries from fabrics. Ordinary cotton and polyester fabrics have been turned into batteries that retain their flexibility.
The demonstration is a boost to the nascent field of "wearable electronics" in which devices are integrated into clothing and textiles. The approach is based on dipping fabrics in an "ink" of tiny tubes of carbon, and was first demonstrated last year on plain copier paper. The new application to fabrics is reported in the journal Nano Letters. "Wearable electronics represent a developing new class of materials... which allow for many applications and designs previously impossible with traditional electronics technologies," the authors wrote.
A number of research efforts in recent years have shown the possibility of electronics that can be built on flexible and even transparent surfaces - leading to the often-touted "roll-up display".
