Smart surveillance doesn’t bother you with trivia

surreal surveillance warning signsWhat could be better than complete panopticon-level surveillance over everything you own? Well, surveillance that only bothers you with issues you really want to know about, and which doesn’t send you an SMS every time the neighbour’s cat rubs itself against the garage door, of course!

The main difference with the Archerfish system is that alerts you by text or video footage only when certain “events” occur, which you define. Alerts can be sent to your cell or similar mobile device, as an email or to a customised web portal.

Unlike more conventional systems, you don’t need to monitor video around-the-clock or trawl through footage or rely on motion alarms.

Using a combination of video cameras, intelligent software (Smartbox) and a custom web portal (SmartPortal), Archerfish watches your premises for “events”. They can be defined as person, vehicle, intelligent object motion or external sensor trigger. This means the system can tell the difference between a human being and inanimate object like a car passing the camera.

At the same time, if the camera is triggered by human movement, you can check to see whether it’s a family member, an intruder or a delivery. You can also check live video through the SmartPortal, as long as you have access to a PC or web-enabled device.

Well, that’s a doozy… provided that you’re willing to trust the software not to goof. And that you’re willing to upgrade the software regularly. And that you’re willing to believe that no one will ever find a way to futz the cameras, or hack the backline hardware via that web portal… but other than that, complete peace of mind! Ain’t technology wonderful? [image by Cory Doctorow]

Crowdsourced justice, or just Vigilantism2.0?

Anonymous vigilantism against Kenny GlennThere’s been a steadily increasing number of stories about “crowdsourced justice” of late, a phenomenon that arguably started in China but which is spreading across the world to anywhere that has a population with ready access to the internet.

For example, you may have heard about the 4chan crusade against one Kenny Glenn, a teenager foolish enough to post videos of himself abusing a kitten; Anonymous doesn’t respect many things, but it sure loves cats, and swiftly unearthed enough information about Kenny to land him in very hot water (and to get the cats rescued, natch).

An article at H+ Magazine takes an in-depth look at the phenomenon, which the Chinese refer to as the “human flesh search engine”:

Fortunately, human flesh search engines don’t end the lives of their victims, like the witch-hunts or lynching of the past.

(Erm… they don’t yet.)

We will not know for some time how these cyber-hunts will shape the future of our privacy, freedom of speech and sense of justice and security. But there is no doubt that these cases are just the beginning a vast social change taking place right now. What we can see from these incidents is that the flow of information will no longer be controlled and that the power of public outrage will not easily be quelled.

Kitten Killer of Hangzhou and her cameraman will walk away from their brutal act.. An apology is hardly appropriate recompense for the death of the tiny tortured feline. But these small stories will remain a part of our collective human memory and help guide the decisions of future societies, because the Internet does not forget, does not forgive and cannot be stopped. Ever.

While containing more than a mote of hyperbole, that final sentence is very telling – not because it is de facto true, but because many people believe it to be true. It’s that motivation combined with the ease of acting upon it en masse that gives human flesh search engines their power. [image sourced from Anonymous’ Kenny Glenn site]

And via SlashDot we find that it’s not just animal abusers who can become the focus of public ire, even in censorship-ridden China: the China Digital Times has a report regarding the dissemination of personal information about one Chen Hua, a deputy director of the Beijing Internet Propaganda Office who was foolish enough to boast of his own corrupt practices to a girl he was seeing “in a personal capacity”. Whether the story is true or not is irrelevant; word got out, the human flesh search engines dug up a lot of Chen’s personal details, and Beijing is now trying to contain the viral spread of said information… which makes me wonder yet again about how effective the blackout on the Tiananmen massacre really is.

Much as with any other technology, the uses to which the internet can be put are decided by the people with access to it; most of these cases could be argued to be ethically justified to a greater or lesser degree (though the lines are as fuzzy as ever), but that may not always be the case. The lord of the flies tends to follow us wherever we go, and I can’t see the transition to the digital world slowing him down too much.

Frank Herbert’s Fremen moisture traps made real

man walking on desert dunesChalk up another point for Frank Herbert; the moisture traps used by his Fremen characters in the Dune series to extract drinkable water from an otherwise bone-dry desert are a technological reality.

Research scientists […] have found a way of converting this air humidity autonomously and decentrally into drinkable water. “The process we have developed is based exclusively on renewable energy sources such as thermal solar collectors and photovoltaic cells, which makes this method completely energy-autonomous. It will therefore function in regions where there is no electrical infrastructure,” says Siegfried Egner, head of department at the IGB. The principle of the process is as follows: hygroscopic brine – saline solution which absorbs moisture – runs down a tower-shaped unit and absorbs water from the air. It is then sucked into a tank a few meters off the ground in which a vacuum prevails. Energy from solar collectors heats up the brine, which is diluted by the water it has absorbed.

Because of the vacuum, the boiling point of the liquid is lower than it would be under normal atmospheric pressure. This effect is known from the mountains: as the atmospheric pressure there is lower than in the valley, water boils at temperatures distinctly below 100 degrees Celsius. The evaporated, non-saline water is condensed and runs down through a completely filled tube in a controlled manner. The gravity of this water column continuously produces the vacuum and so a vacuum pump is not needed. The reconcentrated brine runs down the tower surface again to absorb moisture from the air.

Crafty stuff… and if climate change brings the increased desertification that some suggest it will, there’ll be a lot of people in need of technology just like this. [via SlashDot; image by Gret@Lorenz]

On a similar note, here’s an architectural concept that uses a similar process to extract potable water from air humidity on hot sunny coastlines…

Pseuicide – faking your death on the internet

2 Comments

fake death?Via Chairman Bruce comes a great article at Wired UK about the phenomenon of Munchausen By Internet – members of online communities who fake serious illness or death for a variety of reasons, be it to dig themselves out of their other untruths or because they enjoy being the focus of mass sympathy:

In his 2004 book Playing Sick, Dr Marc Feldman, a clinical psychiatrist at the University of Alabama, offers the first published investigation into a disorder he refers to as “Munchausen by internet”, or MBI, which introduces an online element to the symptoms of Munchausen syndrome, the condition whose sufferers fake sickness and may demand medical treatment for a illness they do not really possess.

“The easy and ready access to the internet propagates MBI,” said Feldman in a recent email. “In fact, I believe that MBI is more common than MS in ‘real life’. The reason is that it is so easy to use the net to research medical conditions, post fallacious materials, and engage others without the need to literally enact an ilness. Many of these people seem to be very lonely, and the internet offers a readily and continually-available source of unconditional support.”

In one startling case, a woman from New Zealand named “Sara” approached Feldman with an 8,000-word confession of her own Munchausen by internet, a story of vast complexity and novelistic detail in which she created more than eight online aliases, constructed intricate relationships between them, and killed at least five.

It’s grimly fascinating to see how the internet is amplifying some of the weirder parts of human psychology. I can’t help but wonder whether or not this might become some sort of performance artform, though; one of the earliest examples of a faked death online was a guy on USENET:

In 1999, when online interaction was still in its relative infancy, a prominent poster on the popular usenet group alt.religion.kibology perpetrated one of the earliest fake deaths, partly as a way “to be a fly on the wall at my own funeral” but also purportedly as part of an investigation into the nature of online relationships. A long-time and regular poster named M Otis Beard suddenly became unusually argumentative with fellow contributors over a brief period, before one of Beard’s friends, who had met him in real life, posted a muted and thoroughly credible notice that Beard had killed himself.

[…]

Some days later, Beard himself resurfaced with a message that, while overbearingly smug in tone, is underpinned by what he claimed was an intellectual motive. After a gleeful pronouncement that “rumors of my death have been greatly exaggerated”, Beard announced that his “little escapade” had been a method of testing the sense of community in the group and had been designed to offer a perverse sense of catharsis when the deception was revealed.

“You thought you had irretrievably lost something; that something is now returned to you,” he wrote. “If I hadn’t made you sad by pretending to be dead, I wouldn’t have been able to make you happy (well, OK, angry and THEN happy) by jumping out of my coffin, whole and hale. Forgive me for putting you through the emotional roller coaster ride, which I hope was a healthily cathartic experience for all of you.”

That sounds exactly like the sort of stunt that the 4chan/Anonymous massive might come up with, keen as they are to shatter expectations, wind up the over-emotional and disrupt internet communities using the very tools used to construct them. I can easily imagine some sort of annual awards for the most convincing, most audacious or most ridiculous faked deaths… and increased awareness of the phenomenon will only make it seem more of a challenge.

Capitalist education? Kids get better grades if you pay for them

3 Comments

Here’s your second “well, duh” story of the day – experiments in New York schools that serve high-poverty demographics indicate that offering kids financial rewards for good grades makes their average results skyrocket.

About two-thirds of the 59 high-poverty schools in the Sparks program — which pays seventh-graders up to $500 and fourth-graders as much as $250 for their performance on a total of 10 assessments — improved their scores since last year’s state tests by margins above the citywide average.

The gains at some schools approached 40 percentage points.

For example, at PS 188 on the Lower East Side, 76 percent of fourth-graders met or exceeded state benchmarks in English — 39.6 percentage points higher than last year, when the kids were in third grade.

At MS 343 in The Bronx, 94 percent of seventh-graders met or surpassed state standards in math this year — 37.3 points higher than last year, when the students were sixth-graders.

In all, of the 61 fourth and seventh grades involved in the pupil-pay program, only 16 improved less than the citywide average gain in math since last year, while 21 did so in reading.

Principals at the highest-scoring schools cautioned that the Sparks program was just one of many factors in the test-score jumps.

But many reported seeing indisputable academic benefits — including more motivation, better focus and an increase in healthy competition for good grades among students.

Now, there’s probably an argument to be made about the sanctity of education and the corruption of kids with money here, but I’m not sure it holds much water beyond staff-rooms. What matters in education is results, right? If you can get kids who are otherwise completely unmotivated to put some effort into learning and bettering their prospects, where’s the problem with spending some cash to do it?

You might say that education should be pitched as being its own reward, and that’s a charming philosophy familiar to me from my privileged middle-class background, but I think it’s pretty safe to say that system evidently isn’t working well among those who most need it. And hey – if you’re preparing kids for entry into a capitalist economy where making money is a tangible and observable benefit by comparison to the more nebulous notion of “bettering oneself intellectually”, why not use money as the carrot at the end of the stick? When idealism has failed, maybe pragmatism deserves a a crack of the whip. [via SlashDot]
