Our goal here at GitHub is to break down the barriers that normally impede collaboration. One of the biggest challenges that we face as developers is keeping track of what other contributors have done. I’ve spent the last month working on GitHub’s answer to that problem and so we’re very pleased to announce the interactive GitHub Network Graph Visualizer!

We found that the bolts that one wants to use are called "Joint Connector Bolts" (seen here: href="http://www.stafast.com/products/screws.html ) -- sometimes shortened as "Connector Bolts" (but that can be somewhat ambiguous if you're asking the person at Lowes for help finding them). if you can find (and afford) the "BA" variety, I imagine that's better, but locally we were only able to find the "BB" type. Here is one place ( http://www.baltimorehardware.com/hardware.cfm/Category/Joint-Bolt-Connectors.html ) that stocks them in many forms, but all BB type. As to the length, you have to be exact in the length on these, or else the flat nuts (that look like the heads) won't fit on the ends of the bolts. If you're going to be joining 2x2's (actual dimensions 1.5"x1.5"), we found that the perfect length of bolt is 70mm.

K-Sketch will allow ordinary computer users to create informal animations from sketches. Current tools for creating animation are extremely complex. This makes it difficult for designers to prototype animations and nearly impossible for novices to create them at all. Simple animation systems exist but severely restrict the types of motion that can be represented. To guide the design K-Sketch, we have conducted field studies into the needs of professional and novice animators. These studies showed the wide variety of motions that users desire in informal animations and indicate how to prioritize these types of motion. Our design allows the most important types of motion to be defined with pen gestures, and gives visual feedback for coordination of events.

Create green jobs and increase energy independence by training people to insulate their own homes, and their neighbors' homes. Let the National Guard lead.
Jon Schull, Associate Professor, Rochester Institute of Technology, firstname.lastname@example.org
Increasing energy efficiency is the shortest path to reducing energy costs, energy dependence, increasing national security, and reducing climate change.
Buildings consume 40% of the US energy budget.
Increasing energy efficiency means lower energy bills for bill-payers, but home-owners must invest now to save energy and lower costs later. This is often psychologically difficult and, these days, economically untenable.
Insulating homes is not rocket science. With a relatively small amount of training, do-it-yourselfers can learn how to evaluate energy-saving opportunities and select and install appropriate materials. Then they can save money by insulating their own homes, and make money by insulating other people's homes and buildings.
So the US government and the National Guard should train people to insulate homes, subsidize material costs, and help create green jobs, reduce energy independence, and combat global warming.
The National Guard is uniquely positioned to lead this initiative:
It is already spearheading sustainability efforts domestically.
It is already in the business of training Guardsmen and women to support national security on the homefront.
The Guard's trainees could immediately apply Guard-delivered training to their own homes.
The Guard's trainees could go on to train others, thus creating a green-collar job creation program.
Optionally, the Guard could further reduce costs and facilitate conversions
by aggregating purchases
negotiating reduced materials costs
making capital investments in equipment (trucks, insulation blowers, etc.)
And who better to receive job retraining, green jobs that can't be sent abroad, tax credits, and home improvement loans than National Guardsmen and women who lost jobs and home improvement opportunities while serving the nation in Iraq and Afghanistan?
High energy prices demonstrably stimulate increases in energy efficiency (which is good) but they also slow down energy-addicted economies, and burden consumers with higher costs. The economic and ecological benefits of high energy costs can be maximized, and the drawbacks minimized by
enforcing a floor on energy costs
using revenues generated by that floor to kick-start a sustainable economy.
Thus, the National Guard is uniquely positioned to kickstart a sustainable economy, and a more stable and secure America.
"Investing in a home on your street could be more profitable than investing on Wall Street." -- http://hes.lbl.gov/hes/vh.shtml
in home energy retrofits might yield more national security and
stability benefits per dollar than anything else the National Guard
might undertake" –Jon Schull, Associate Professor, Rochester Institute

Jonathan Schull is an entrepreneur, inventor, and tenured Associate Professor of Information Technology at Rochester Institute of Technology (RIT) and an affiliate of RIT's new Golisano Institute of Sustainability. Now in his third career, Schull is the author of twelve patents, specializes in action-oriented technology and innovation, and is currently co-chair of the task force organizing RIT's new Center for Student Innovation.
Schull obtained a B.S. in psychology from Reed College in 1975 and a Ph.D. in biological psychology from University of Pennsylvania in 1980; he was a professor of Biological Psychology at Haverford College from 1980 until 1992. In 1992 Schull gave up tenure to start one of the first digital rights management companies. SoftLock.com eventually became a 75-person publicly traded company called DigitalGoods.com (NASDAQ:DIGS). After the collapse of the internet bubble in 2001, Schull joined RIT, where he teaches courses on Interaction Design and Innovation and Invention, and has organized and executed a number of technology-enabled social action projects. These include QuakeHelp.net, a social action website that organized the collection and transport of winter survival gear to earthquake victims in Pakistan; RochesterDigitalRipple.com, helping 20 inner city young people assemble and install a community wireless network in their troubled neightborhood; and helping General Motors assess opportunities for making the OnStar system more accessible to deaf and hard-of-hearing individuals.

By way of thanks, I sent him a few links to current trends (with notes on opportunities, you might want to explore...perhaps with some of our more entrepreneurial innovation students.)
- A New Zealand company that has brilliantly "consumerized" your business. I send them line drawings, they send me laser-cut objects. ( http://www.ponoko.com/ But they're shipping from New Zealand . I imagine they could use a North American fab-site.)
- Fabbing as popular (geek) culture. (or, why you are changing the world)
by Neil A Gershenfeld - 2005 - 289 pages
- http://www.fabbaloo.com/ a blog that tracks this stuff
- Google Sketchup. An extraordinary, and extraordinarily free, 3D modelling program.
Soon, someone will tie this right in to a laser cutting rig...

Why should I use this API over the other two Python Twitter APIs in PyPi?
- It's minimalist. Small. Simple. Don't you like simple?
- Its methods are directly bound to the Twitter API's URLs. For instance
twitter.statuses.friends_timeline()will always hit the URL
http://twitter.com/statuses/friends_timeline.json. Always. When Twitter decides to change them you won't have to update your version of the API (though you may have to update your code. Sorry, can't help that).
- The command line tool is pretty swell, I think.
- The Twitter IRC bot has no parallel (that I know of).

QR Codes are a popular type of two-dimensional barcode, which are also known as hardlinks or physical world hyperlinks. QR Codes store text, which can be a URL, contact information, telephone number, even whole verses of poems!
QR codes can be read by any device that has the appropriate software installed. Such devices range from dedicated QR code readers to mobile phones.
Specify a QR code with
