Strategyzer: Your Business Model Toolbox NSA-proof your e-mail in 2 hours You may be concerned that the NSA is reading your e-mail. Is there really anything you can do about it though? After all, you don’t really want to move off of GMail / Google Apps. And no place you would host is any better. Except, you know, hosting it yourself. Today we kill your excuses. Now fair warning: it took me about two days to figure the stuff out you’re going to see in this blogpost, starting from knowing basically nothing about modern e-mail servers. So bookmark this blog post, block off a Saturday next month, and get it done. Edit Some people are complaining that the NSA is pulling all the e-mail over the wire anyway, so encrypting your own server is stupid. In the next two hours, we’re going to fix this. You’re going to host your own mail.It’s going to be encrypted on the server, locked-on-boot, SSH on reboots to unlockWhile we’re at it, let’s fix some things that annoy me about GMail:Better SPAM detection. I’m going to assume: Hang on just a minute though. Let’s get started!
How To Build A Low-Cost “Wi-Fi Mesh Network” For Emergency Communication ⚙ Co.Labs ⚙ Code + Community When tropical storms hit New York City, internet connectivity is often the first thing to go down. The next time it happens in the low-lying coastal community of Red Hook, Brooklyn, it will be a group of teenagers running something called a Wi-Fi Mesh Network that will come to the rescue--providing a model for a low-cost, community-built solution to the so-called Last Mile gaps that the massive telcos can’t (or won’t) bridge. 1Reaction A year ago, a community organization called Red Hook Initiative (RHI) had just started a pilot program for a Red Hook Wi-Fi mesh. In the hurricane’s aftermath, RHI handed the reins of the Red Hook Wi-Fi mesh project to a new group calling themselves The Digital Stewards, comprised of eight 19- to 25-year-olds. As it turns out, RHI has lots of experience getting middle school and high school kids in its youth programs to stay on for leadership positions, but the Digital Stewards is a one-of-a-kind job training experience.

MockFlow - Online Wireframe Tool and Design Cloud Sovereign Peer-to-Peer Build Your Own Internet with Mobile Mesh Networking After an earthquake crippled Haiti in 2010, killing and injuring hundreds of thousands and destroying the country’s communication networks, Paul Gardner-Stephen found himself thinking about all the cell phones that had instantly become useless. With cell towers out of commission across the country, they would be unable to operate. “If the software on the phones was right,” he says, “they would keep working for at least localized communication, handset to handset.” Gardner-Stephen, a research fellow at Flinders University in Adelaide, Australia, now leads a project that enables Android phones to do just that. This approach, known as mesh networking, is not a new idea (see “Automatic Networks”). Some communities in Washington, Brooklyn, and Detroit already have Wi-Fi-based mesh networks built on Commotion’s technology. “You could have someone taking pictures and video at a protest and sharing them immediately to the mesh,” he says.
Debuts New Open Source Digital Storytelling Tool - BBG The Broadcasting Board of Governors launched KettleCorn today, a new digital tool that will allow journalists to enhance, remix and share interactive web videos by combining audio and video with live web content. KettleCorn is built on the open source popcorn.js framework, adapting the previously existing Mozilla Popcorn Maker for journalists’ needs. Leveraging open source technologies allows the BBG a cost-effective way to adapt existing technology by building in core features crucial to journalists working in a multilingual, fast-paced environment. “KettleCorn is a storytelling tool designed specifically for journalists, even those without a technical background” said Rob Bole, BBG’s Director of Innovation. “By using this tool with the enhancements we tailored for our industry, our journalists are able to create something in 20 minutes which would previously have taken several hours.”
Bittorrent in a P2P social network Kategorie:English – wiki.freifunk.net For Freifunk/Google Summer of Code, please check out our Ideas or documentation at GSoC. Freifunk (German for Free Radio) is an initiative to support the development of tools for free mesh networks. Besides that the initiative supports communities developing know-how to set up their own networks. The freifunk community is is part of a network of projects developing tools for mesh networks including the Freifunk Firmware and OpenWrt projects, routing protocols such as OLSR and B.A.T.M.A.N., tools like Maps for networks (e.g. freimap), scanning tools like the horst tool and many more. Recently people also started to develop Open Hardware like the Mesh Potato for villagetelco. With the freifunk firmware it is relatively easy to bring up new wireless mesh networks using ad-hoc WLAN communication layer 2 and layer 3 routing with OLSR, BATMAN and other protocols. FREIFUNK Firmware/OPENWRT The Freifunk Firmware is a modified version of OpenWrt Linux Version that is developed for router devices.
