I think Tyger, but whether because of my name or the Blake poem I'm not sure! I must confess that, although cats have more flash, there is something eminently pragmatic about prehensile.

"xenomorphic tail grafting," eh? Let me guess: "Xeno" is "foreign" or "other" and "morphic" means it pertains to "forms" (in approximately the Platonic sense), so is "xenomorphic tail grafting" what you get when, say, you graft a dog's tail onto a monkey?

EFF: Mesh Networking, Good. Overbroad Patents, Bad.

by Eddan Katz

another legal aspect of the sudo-mesh project is patent busting prior art research. ... https://www.eff.org/deeplinks/2013/06/mesh-networking-good-overbroad-patent… > JUNE 21, 2013 | BY JULIE SAMUELS > Mesh Networking, Good. Overbroad Patents, Bad. Help Us Protect Mesh Networking. > Earlier this year, we announced that along with the Cyberlaw Clinic at Harvard’s Berkman Center for Internet and Society, we were challenging six patent applications that, if granted, could threaten the … [View More]development of 3D printing technology. We asked you—the community—for help, and your input was invaluable. We're still waiting to hear from the Patent Office on those applications, but our work is not done. We need your help again, this time to challenge dangerous patent applications that threaten mesh networking technology. > > Mesh networking allows users to form their own networks without a centralized infrastructure, making them inherently resistant to censorship, surveillance, and disruption. Given recent revelations showing widespread surveillance of the phone calls and online activities of innocent Americans and others around the globe, the development of mesh networks more important than ever. Governments and commercial actors have taken advantage of intermediaries as “weak links” in order to censor, surveil, and disrupt communications and social movements. Already in the United States, cell towers have been deactivated in response to planned protest, while activists in countries such as Egypt, Libya, and Syria have suffered massive blackouts that shut down all access from within the country to the wider Internet. Mesh networking technology can help activists fight back. > > Wireless Mesh Networks > > For more than a decade the open-source community has been developing networks that use multi-hop connectivity to bypass the current ISP-dominated model of Internet access. These Wireless Mesh Networks (WMNs) have tremendous potential for enabling the free flow of information without exposure to censorship and monitoring. Because they lack a central access point, mesh networks are also harder to take down, as the removal of one node won’t terminate the entire network. And WMNs, by not relying on infrastructure provided by ISPs, can provide connectivity in areas where that infrastructure is inaccessible, damaged, or prohibitively expensive. > > The open source community has developed innovative tools and applications of mesh networking technology including the B.A.T.M.A.N. routing protocol developed by Freifunk, a system for internet access in remote areas of Afghanistan and Kenya (FabFi), and community controlled telephone systems in Nigeria, Columbia, Puerto Rico, South Africa, East Timor, and Brazil (VillageTelco). Harvard Law Professor Jonathan Zittrain and former FCC chairman Julius Genachowski recently advocated for the use of mesh networks to provide phone access during times of crisis when mobile networks are overloaded. > > The Problem > > Wireless Mesh Networking is still in its nascent stages, and the innovations and experimentation of the open source community are playing a vital role in advancing the technology. However, there has also been significant proprietary and military interest in the technology, and companies are seeking patents in many areas of WMN already explored by the open source community. We unfortunately know what can happen when overbroad patents get granted—the rise of patent trolls, lawsuits that can threaten growing businesses, and threats that target entire areas of technology. We don't want to see that happen to mesh networking. > > This is where you come in! > > We have identified several patent applications that we believe particularly threaten the free development of mesh networking technology. There is a danger that these patents, if granted, will lock up the basic mesh network infrastructure and restrict advancement of and access to the technology. > > We have been using the Patent Office’s new Preissuance Submissions procedure, which gives third parties an opportunity to tell patent examiners when they think a patent application shouldn't be granted. The procedure requires those third parties to submit publications predating the application that prove the ideas in the patent were not novel. > > Which is why we need your help. We are again partnering with Ask Patents so you can help us identify the best prior art to reign in these applications. While prior art for issued patents must date back many years, these are recently filed applications for which relatively recent publications may be helpful.

Node map!

by Marc Juul

I set up a mapping application so we can start mapping out potential nodes. If you add a node, please put information about whether we'd have access to put a node node on the roof or mount it on the side of the building, or only inside the building, and put your name so we know who to talk to about each node. http://meshmap.sudoroom.org/

Name and logo discussion and brainstorm

by Marc Juul

Hi. I wanted to get the name and logo discussion off the ground. First a bit of history as i understand it: In 2009 Mark Burdett (and others) started an east bay community mesh networking project called 510pen. It had several nodes in Oakland (maybe 20+), and still has a few active nodes. The routers used were open-mesh.com routers, which come pre-configured for mesh. 510pen applied for some decent amount of funding (Mark can elaborate) but did not get it. Over time the project stagnated and … [View More]
