University of Washington computer scientists have created a low-cost gesture recognition system that runs without batteries. They call it AllSee, and it uses ambient TV signals as both a power source and as a means to identify a user’s gestures.
Txchnologist has reported on earlier battery-free, wireless sensors produced by the team. Their latest advances refine the concept and show that they can use an ultra-low-power receiver to analyze changes to nearby wireless signals caused by hand gestures. They equipped a smartphone with the receiver and changed the volume of music with a gesture while the device was inside the user’s pocket.
Their system costs less than a dollar to produce and consumes microwatts of electricity, meaning it can remain on and enabled. They say their sensor can also be embedded in other electronics to enable gesture control through body motions.

#a sense of place
The Sacrificial Landscape of True Detective
True Detective is a compelling show. People love the acting and are thrilled by the mystery. No arguments there. But two recent interviews with people who worked on it highlight another reason the show works: the petrochemical landscape of Louisiana.
The sense of place is what has struck me about all my favourite dramas of late.
The location as a character in the story, interacting with others…
I have not yet watched this show (my resources are limited) but everything I’m hearing puts it on the list.
What is my child doing on the Internet now?
Gosh I wish I could sit down.
It’s okay I’ll just lean against this wall of snow.
IT IS MARCH WTF. I’m so done with this.
"I wish I’d partied a little less. People always say ‘be true to yourself.’ But that’s misleading, because there are two selves. There’s your short term self, and there’s your long term self. And if you’re only true to your short term self, your long term self slowly decays."
The Only Woman in the Computer Science Department
Irene Greif always thought she’d be a teacher. “For one thing,” she told me, “I’d been told by my mother that it was good to be a teacher because you just worked the hours your kids were in school and you could come home.” It had just always been the profession in the back of her mind, the default.
So then it must have been a bit of a shock when, after becoming the first woman ever to receive a Ph.D. in computer science from MIT, Greif discovered that she didn’t really enjoy teaching—she much preferred research. And so eventually she left teaching as a professor and did what she did best: studying, thinking, and figuring systems out. She founded a research field, computer-supported cooperative work, and has spent her life figuring out how to build better systems for humans to work together.
Greif recently retired from IBM, where she’d been since the mid-’90s, and is hoping to devote some time to encouraging young women to go into STEM fields and coaching them to stick with them—a twist on teaching that she does genuinely like.

In Ukraine, We’re Witnessing What Comes After the War on Terror
Maybe this is how the “war on terror” ends.
Since entering his second term, President Obama has signaled his desire to close out a foreign-policy era that he believes has drained America’s economic resources and undermined its democratic ideals. But it hasn’t been easy. Partly, Obama remains wedded to some of the war on terror’s legally dubious tools—especially drone strikes and mass surveillance. And just as importantly, Obama hasn’t had anything to replace the war on terror with. It’s hard to end one foreign-policy era without defining a new one. The post-Cold War age, for instance, dragged on and on until 9/11 suddenly rearranged Americans’ mental map of the world.
Now Russia may have solved Obama’s problem. Vladimir Putin’s military intervention in Ukraine doesn’t represent as sharp a historical break as 9/11 did, but it does offer the clearest glimpse yet of what the post-war on terror era may look like. To quote Secretary of State John Kerry, what comes after the war on terror is the “19th century.”

So my husband and i have been keeping track of this in the news, and last night I wanted a little more clarity.. so I dug out my history atlas from my undergrad days. It has maps of the world over time.
Then I went down a road of global geopolitical theories on wikipedia and wow. Seems like stability is the outlier here.
"A group of about 500 Icelanders had arrived at Port
Hope, Ont., on their way to settle around the Gimli area
of Manitoba. The Icelandic agent, John Taylor, was
looking for a guide with wilderness experience to help
them on their trip westward. He heard of young Everett
Parsonage and commissioned him for 10 months, at
$10.00 a month, to be their guide.
It was 1875 when they left Port Hope. They went by
boat to Duluth. From there they came by Northern
Pacific to Fisher’s Landing. Here they commenced their
long journey on the Red River, in flat bottom boats, to
the mouth of the Red River. Here they were met by a
Hudson Bay steamer and towed to Willow Island, where
they disembarked after a very long and tedious journey.
It was on this trip that Everett became close friends
with Sigurdur Christopherson, Skafti Arason, Krist jan
Jonsson, John Taylor and many more of the Icelanders.
Five years later, in 1880, when Everett was established on
his homestead in Pilot Mound, he was instrumental in
persuading the Icelanders to explore the possibilities of
starting another settlement in the Tiger Hills area, now
the Municipality of Argyle."
