Tristan sez, "Open Source Ecology is a social enterprise based in Missouri. We develop open source machines that can be made for a fraction of commercial costs, and share our designs on the Internet for free.
We've just designed version 4.0 of our compressed earth brick press, the Liberator. With this machine, anyone can make solid, 'dirt cheap' structures from the earth beneath their feet.

4chan, the Internet's long-time dumping ground and butt of many a joke, is getting serious about software by making their biggest public-facing code change in nearly a decade, introducing an API and a bunch of new functionality.
Given its reputation, many commentators have already written this off with a shrug and a laugh. But 4chan is also one of the web's most popular and influential communities. It's the source of so many Internet-age cultural trends that even your grandma may be dimly aware that the clever picture she posted on her Facebook was trawled a thousand copies ago from the dark depths of /mlp/. Given that there's big money in all this, the API offers businesses a direct line to the heart of the machine.
As a professional software developer and long time 4chan user, I think this is a pretty interesting development. I talked yesterday afternoon to some of those who worked on 4chan's code over the years and know a little about why this is such an important development.
Here's an interesting, short memoir about science fiction in Africa, written by Jonathan Dotse, a science fiction writer in Accra, Ghana. Dotse describes how his early exposure to science fiction changed his outlook on life, and how he sees the field relating to the future of Africa.
Imagine a young African boy staring wide-eyed at the grainy images of an old television set tuned to a VHF channel; a child discovering for the first time the sights and sounds of a wonderfully weird world beyond city limits. This is one of my earliest memories; growing up during the mid-nineties in a tranquil compound house in Maamobi; an enclave of the Nima suburb, one of the most notorious slums in Accra. Besides the government-run Ghana Broadcasting Corporation, only two other television stations operated in the country at the time, and satellite television was way beyond my family’s means. Nevertheless, all kinds of interesting programming from around the world occasionally found its way onto those public broadcasts. This was how I first met science fiction; not from the tomes of great authors, but from distilled approximations of their grand visions.
This was at a time when cyberpunk was arguably at its peak, and concepts like robotics, virtual reality, and artificial intelligence were rife in mainstream media. Not only were these programs incredibly fun to watch, the ideas that they propagated left a lasting impression on my young mind for years to come. This early exposure to high technology sent me scavenging through piles of discarded mechanical parts in our backyard; searching for the most intriguing sculptures of steel from which I would dream up schematics for contraptions that would change the world as we knew it. With the television set for inspiration and the junkyard for experimentation, I spent my early childhood immersed in a discordant reality where dreams caked with rust and choked with weeds came alive in a not-so-distant future; my young mind well aware of the process of transformation occurring in the world around me; a world I was only just beginning to understand.
Developing World: Beyond the Frontiers of Science Fiction
CBC's long-form/big think radio program Ideas recently featured a lecture called "Feeding Ten Billion"
from Raj Patel
, an Africa development scholar formerly with the World Bank, and author of The Value of Nothing
. Patel's perspective on global agriculture and social justice is incisive and contrarian. I've never heard anyone talk about the demerits of the "Green Revolution" in agriculture like this, and it was an eye-opener. A perfect hour-long listen for the weekend's chores. MP3 link
You are invited to participate in a design competition for development of sustainable technologies and their components for printing on open source 3-D printers!
The goal of the contest (organized by Queen's University Applied Sustainability Lab and Michigan Technological University) is to facilitate an open exchange of 3-D sustainable technology designs that can be printed to meet various needs in the context of sustainable and self directed development.
3-D printers such as RepRap and open sourced innovation hold great promise for development of technologies to help millions of world's poorest communities reach a better standard of living. Designs will be judged on the technical printing viability, feasibility and functionality of the innovation, as well as ecological, economic and social sustainability.
Anyone can enter the competition however the contestants must post their digital designs on Thingiverse under an open license (e.g. CC-BY-SA). The contest is funded by the Queen's Applied Sustainability Group and the Natural Sciences and Engineering Research Council of Canada (NSERC). Competition closes February 1st 2012.
Top prize is CAD1,000, second is CAD500, and there will be three runners up who get a satisfied glow. All winners also get a copy of my novel Makers, which is pretty flattering, if I do say so myself!

PeePoo bags are alternatives to the "flying toilets" (plastic bags filled with human shit and then flung into the public street) used in Nairobi shantytowns. Created by the company PooPeople, they're lined with a thin gauze layer filled with urea powder, which neutralizes the bacteria in human feces. Once filled, the bags turn the poop into fertilizer, then biodegrade.
The Peepoo is in the form of a slim elongated bag measuring 14 x 38 centimeters.
Within the bag there is a thin gauze layer measuring 26 x 24 cm. The Peepoo is filled with urea powder. Without sacrificing ergonomic function, the bag’s design is adapted in every way so that it might be manufactured at as low a price as possible and sold to groups with the weakest purchasing power in the world.
The Peepoo is easy to carry and easy to use. It doesn't need any supporting structure, but, for convenience, a small bucket can help a lot.
