Pure Water for Haiti, Afghanistan: Just Add Bacteria

bacterial water cleaner

Pentagon-backed researchers have come up with a novel new way to purify water: Just add bacteria.

Scientists at Sam Houston State University (SHSU) have successfully designed portable, efficient, bacteria-based water treatment units. Two of the devices are on their way to Army bases in Afghanistan, and the research team is in talks with the Pentagon about sending a working prototype to help relief efforts in Haiti.

The systems, called “bio-reactors,” clean putrid water using the same bacteria you’d find in a handful of dirt. The bacteria filter the water, then eat up the sludge that’s a common byproduct of waste treatment. It’s all done in less than 24 hours, and from devices smaller than a standard shipping crate.

City Dwellers Drive Deforestation in 21st Century

deforestation

Globally, roughly 13 million hectares of forest fall to the blade or fire each year. Such deforestation has long been driven by farmers eking out a slash-and-burn living or loggers using new roads to cut inroads into pristine forest. But now new data appears to show that, at least for the first five years of the 21st century, big block clearings that reflect industrial deforestation have come to dominate, rather than smaller-scale efforts that leave behind long, narrow swaths of cleared land.

A 50-Watt Cellular Network

An Indian telecom company is deploying simple cell phone base stations that need as little as 50 watts of solar-provided power. It will soon announce plans to sell the equipment in Africa, expanding cell phone access to new ranks of rural villagers who live far from electricity supplies.

Characteristics of Open Source Warfare

MEND

Sean Gourle’s list of the characteristics that define open source warfare. These are some points I found particularly interesting:

7. Tall poppy: The strongest groups are the predominant targets for opposition forces Internal competition: There is direct competition amongst insurgent groups for both resources and media exposure. They are competing with each other in addition to fighting the stronger counterinsurgent forces.

8. Independent co-ordination: Autonomous groups act in a coordinated fashion as a result of the competition that exists between them.

9. Emergent structure: Attacks in both Iraq and Colombia become ‘less random’ and more coordinated over time

Zoroastrian Celebration Sadeh

Zoroastrian Celebration Sadeh

Sadeh is an ancient Iranian tradition celebrated 50 days before nowrouz (Persian New Year). Sadeh in Persian means “hundred” and refers to one hundred days and nights left to the beginning of the new year celebrated at the first day of spring on March 21 each year. Sadeh is a mid winter festival that was celebrated with grandeur and magnificence in ancient Iran. It was a festivity to honor fire and to defeat the forces of darkness, frost, and cold.

Twitter works on technology to evade censors in China and Iran

Twitter, the internet social network, is developing technology it hopes will prevent the Chinese and Iranian governments being able to censor its users. […]

Mr Williams, speaking at the World Economic Forum, said he admired Google for its decision last month to confront China over censorship and cyberattacks on its service, but said Twitter was too small to take a similar stand.

“We are partially blocked in China and other places and we were in Iran as well,” he said. “The most productive way to fight that is not by trying to engage China and other governments whose very being is against what we are about. I am hopeful there are technological ways around these barriers.”

Mr Williams said Twitter had an advantage in evading government censors through operating as a network of internet and mobile applications, rather than as a single website. “Twitter is a network that is accessed in thousands of ways.”

Is tech taking us to a world more medieval than modern?

cyberwarfare

For most people over most of man’s time, however, history is more like a mob movie than a courtroom drama: The Vikings burn the village, the Huns or Mongols ride through with swords, child soldiers arrive in pickup trucks. Violence is the only argument. That is history, too chaotic and reactive for any organized telling.

The mayhem Menn portrays is not that stark, but it seems closer to that than to a world of rules and order. Cybergangs rise and fall in varying degrees of anonymity and alliances with Russian, Chinese and other governments that are more ad hoc than understood. Norms of behavior among individuals and governments are a moving target. Crimes are not solved as much as controlled, through informal alliances of small agencies within and outside the state, or when there is publicity of the crimes that embarrasses higher ups in government. It is crime and crime fighting within a massive, illicit social network, fueled on greed, speed and reputation.

This sounds partially right, except that it overlooks the amount of thuggish violence governments have continued to be involved in – wars, strikes, proxy wars, assassinations, etc. If we’re moving into a world of cyberwarfare instead of physical warfare: great. I’d rather people get their “identities stolen” than end up dead. I’d like to think that’s happening, rather than a mere expansion of aggression. Whatever the case, there’s never been a time when governments didn’t act like gangs.

Defense contractor to remove Bible references

A Michigan company that manufactures combat rifle sights for the U.S. military that carry Bible verse citations said Thursday it would send kits to remove the inscriptions, NBC reported.

Trijicon Inc. also said it would take off Biblical references from all U.S. military products that are still in the company’s factory and ensure future items do not have any inscriptions on them.

Guardian Launches Search Engine for Government Data from Around the World

world government data

The UK Guardian, ostensibly a newspaper but a major proponent for opening data held by governments to use by outside software developers, has launched some software of its own: a search engine that unearths datasets and pathways to data sets provided by governments around the world. World Government Data Search is now live.

Yesterday the UK government released its new data site, data.gov.uk, to rave reviews (including ours). The new Guardian search engine searches across the UK, US, New Zealand and Australian governments’ data sites. The company also offered up a gallery of the 10 best visualizations and mash-ups built on top of government data like this.

South Korea considering virtual currency real

The Supreme Court acquitted two defendants in a case related to the legality of using cash to buy and sell cyber money for online games.

The court conditioned its ruling on the fact that the cyber money was earned through skill, not luck.

Supreme Court Justice Min Il-young ruled in favor of the suspects surnamed Kim and Lee.

The two allegedly purchased “Aden,” cyber money in an online multiplayer role-playing game “Lineage,” worth 234 million won ($207,558), which was lower than market price, through game item-trading Web sites.
