La suite : A Processing model for Tanaka contours
If you follow my blog, you’ve most certainly seen the post How to create illuminated contours, Tanaka-style from earlier this year. As Victor Olaya noted correctly in the comments, the workflow to create this effect lends itself perfectly to being automated with a Processing model.
The model needs only two inputs: the digital elevation model raster and the interval at which we want the contours to be created.

The Twilight of Saudi Power
Saudi Arabia’s King Abdullah died last week during what some saw as the height of his kingdom’s resurgence in a volatile region. As turmoil has engulfed governments across the Middle East since the Arab uprisings, Saudi Arabia has seemed to remain a potent pillar of stability. “[F]ar from undermining the Saudi dynasty,” wrote David Kirkpatrick of The New York Times on Sunday, “chaos across the region appears instead to have lifted the monarchy to unrivaled power and influence.”

The Smithsonian’s Cooper Hewitt: Finally, the Museum of the Future Is Here - The Atlantic

Some things belong in a museum. But at the Smithsonian’s recently reopened museum of design, a team has been rethinking what a thing is in the first place.
The Cooper Hewitt has transformed into an organization not unlike Wikipedia (...) : Somewhere between a media and a tech firm, it is a Thing That Puts Stuff on the Internet. Or, more precisely, A Thing That Puts Things on the Internet.
Cope held up his smartphone at one point and pointed at it. “Everyone walks in with one of these,” he said. “We’re gonna have to find a different way to air-quote compete, so why don’t we just try to meet people halfway? All the visitors arrive with superpowers.”
(...) But the real treats are in the museum’s interactives that draw from its collection. they were created in collaboration with the Labs team, and—more importantly—they used an infrastructure developed by the team. It is the infrastructure that lets the museum plan for the near future, that lets it bridge digital and physical, that lets it Put Things on the Internet: the API.
(...)the API at the center of the museum.” The Cooper Hewitt’s API connects to the museum’s two operational databases—its vast collections database and its complex customer and ticketing databases—and fuses them. Then it makes the collections part public and accessible.
(...) What the API means, for someone who will never visit the museum, is that every object, every designer, every nation, every era, even every color has a stable URL on the Internet.
(...) these shareable and permanent URLs start to stand in for the locked-away object.
(...) “What ’digital’ in the museum means is really that everything is available whenever you want. Wherever you want, whenever, however"
The Cathedral of Computation - The Atlantic

I don’t want to downplay the role of computation in contemporary culture. Striphas and Manovich are right—there are computers in and around everything these days. But the algorithm has taken on a particularly mythical role in our technology-obsessed era, one that has allowed it wear the garb of divinity. Concepts like “algorithm” have become sloppy shorthands, slang terms for the act of mistaking multipart complex systems for simple, singular ones. Of treating computation theologically rather than scientifically or culturally.
This attitude blinds us in two ways. First, it allows us to chalk up any kind of computational social change as pre-determined and inevitable. It gives us an excuse not to intervene in the social shifts wrought by big corporations like Google or Facebook or their kindred, to see their outcomes as beyond our influence. Second, it makes us forget that particular computational systems are abstractions, caricatures of the world, one perspective among many. The first error turns computers into gods, the second treats their outputs as scripture.
Computers are powerful devices that have allowed us to mimic countless other machines all at once. But in so doing, when pushed to their limits, that capacity to simulate anything reverses into the inability or unwillingness to distinguish one thing from anything else. In its Enlightenment incarnation, the rise of reason represented not only the ascendency of science but also the rise of skepticism, of incredulity at simplistic, totalizing answers, especially answers that made appeals to unseen movers. But today even as many scientists and technologists scorn traditional religious practice, they unwittingly invoke a new theology in so doing.

A Walk Along the Swiss Border
In a few weeks, Switzerland will vote on a proposal to dramatically restrict immigration. A group called Ecopop has gathered enough signatures to hold a referendum that proposes to limit immigration to 0.2 percent of the resident population. The new limit would be 75 percent lower than current levels, about 16,000 immigrants per year. Reuters photographer Denis Balibouse took the occasion to make a photo survey of the border regions Switzerland shares with France, Italy, Germany, and Austria. [21 photos]

Nine months before the September 11 attacks—and just days after the Supreme Court halted the Florida recount, handing the presidency to George W. Bush—U.S. intelligence officials published an 85-page prediction for what the world would look like in 2015. It’s a world that seems familiar in some ways, and utterly foreign in others. And it’s a world in which power is diffusing and decaying—reflecting one of the most significant trends of 2014 and perhaps the coming year as well.

Advances in neural engineering have enabled direct control of insect locomotion. Insect biobots, with a natural ability to crawl through small spaces, offer unique advantages over traditional synthetic robots. A cyberphysical network of such biobots could prove useful for search and rescue applications in uncertain disaster environments. Our previous work has demonstrated control of Madagascar hissing cockroaches using a Kinect-based computer vision platform. We now demonstrate lowpower insect-mounted acoustic sensors for future use in both environmental mapping and localization of trapped survivors. Our experimentation has shown the capability of an insect mounted array of microphones to localize a sound source.
The goal is to use the biobots with high-resolution microphones to differentiate between sounds that matter – like people calling for help – from sounds that don’t matter – like a leaking pipe,” Bozkurt says. “Once we’ve identified sounds that matter, we can use the biobots equipped with microphone arrays to zero in on where those sounds are coming from.

These Are the #Emails #Snowden Sent to First Introduce His Epic NSA Leaks
Six months before the world knew the National Security Agency’s most prolific leaker of secrets as Edward Joseph Snowden, Laura Poitras knew him as Citizenfour. For months, Poitras communicated with an unknown “senior government employee” under that pseudonym via encrypted emails, as he prepared her to receive an unprecedented leak of classified documents that he would ask her to expose to the world.
My personal desire is that you paint the target directly on my back. No one, not even my most trusted confidant, is aware of my intentions and it would not be fair for them to fall under suspicion for my actions. You may be the only one who can prevent that, and that is by immediately nailing me to the cross rather than trying to protect me as a source.

War Gear Flows to Police Departments (juin 2014)
▻http://www.nytimes.com/2014/06/09/us/war-gear-flows-to-police-departments.html
During the Obama administration, according to Pentagon data, police departments have received tens of thousands of machine guns; nearly 200,000 ammunition magazines; thousands of pieces of camouflage and night-vision equipment; and hundreds of silencers, armored cars and aircraft.
The equipment has been added to the armories of police departments that already look and act like military units. Police SWAT teams are now deployed tens of thousands of times each year, increasingly for routine jobs. Masked, heavily armed police officers in Louisiana raided a nightclub in 2006 as part of a liquor inspection. In Florida in 2010, officers in SWAT gear and with guns drawn carried out raids on barbershops that mostly led only to charges of “barbering without a license.”
Etats-Unis : Des brindilles et des faisceaux - Badia Benjelloun

Depuis que les Us(a) ont baissé le niveau d’intervention de leurs forces armées combattantes terrestres de par le monde, la surproduction guette un segment du secteur de l’armement. Des hélicoptères, des MRAPs (les fameux Humvee transformés par les Israéliens pour servir en Irak), du matériel de vision nocturne, des mitraillettes, des véhicules de combat légers et autre quincaillerie équipent maintenant les polices départementales.
Une petite ville de 25.000 habitants comme celle de Neenah, dans le Wisconsin, a le plus faible taux de criminalité des Us(a) et n’a pas connu d’homicide depuis plus de 5 ans. Sa police dispose néanmoins d’armement de guerre et elle se doit d’entraîner ses éléments à leur maniement.
Au passage, je signale le compte Twitter des « graphiques du New York times » :
▻https://twitter.com/nytgraphics
Et pas que le matériel - j’émet l’hypothèse que l’afflux de vétérans de la #GWOT dans les forces de police contribue à en faire dériver la culture du maintien de l’ordre vers une culture militaire.
Nan, pour l’instant ce n’est qu’une impression diffuse - je chercherai. Par contre j’aime bien cette remarque trouvée dans un article (▻http://www.mercurynews.com/breaking-news/ci_23886231/from-military-police-force-natural-transition) sur la transition de carrière de l’armée à la police: "many people who have gone to combat for any amount of time have got some stuff that they need to work on" - voilà, c’est une bonne partie du problème.

Certes ça peut servir pour approcher un forcené retranché, mais ce n’est pas à ça qu’il est destiné - les policiers locaux précisent que ce n’est pour eux pas un véhicule de forces d’intervention: “This is not just a SWAT ride. What we want to do is get everybody patrol-trained” - c’est vraiment une généralisation de la conception militaire de la patrouille.
Cet article approfondit bigrement la question - ▻http://www.hamptoninstitution.org/coming-home-to-roost.html
A propos de l’Iraq: "Considering the savagery that accompanies such an environment, it is not difficult to see how undervalued human life becomes" - on peut imaginer les conséquence sur l’approche du métier de policier.
Et j’y trouve le genre d’analyse que je cherchais:
" Police training mimics military training, both physically and mentally. Transition programs that funnel soldiers to police forces have become common at all levels of government. The changing face of law enforcement is indicative of this process as forces that are traditionally advertised to “protect and serve” have become noticeably militaristic. Perhaps even more concerning is the fact that soldiers, many of whom carry the mental baggage of war, are being streamlined from the streets of Fallujah to the city blocks of the US.
In a recent article for “Police: The Law Enforcement Magazine,” Mark Clark tells us that military veterans seeking employment in police ranks “is happening right now in numbers unseen since the closing days of the Vietnam War.” To assist with job placement and transitioning, organizations like “Hire Heroes USA” works with “about 100 veterans each week” - at least 20% of whom are seeking law enforcement jobs. Law enforcement agencies like the Philadelphia Police Department and San Jose PD, which boast of being structured as “a paramilitary organization,” actively seek military veterans by awarding preferential treatment. Many police departments across the country have added increased incentives and benefits, including the acceptance of military active duty time towards retirement, to acquire veterans.
An October 2013 edition of the Army Times reports that “more than seven in 10 (local law enforcement agencies) said they attend military-specific job fairs, and three quarters reported developing relationships with the Labor Department’s local veterans employment representatives.” Also, “Half said they work with military transition assistance programs, and half also said they develop relationships with local National Guard and reserve units”. Most local departments also have some type of veterans hiring preference, and “more than 90 percent reported having at least one vet in a senior leadership position.”
An example of this trend can be found in Hillsborough County, Florida, where the Sheriff’s department is seeking to hire “200 law enforcement deputies and another 130 detention deputies,” and Major Alan Hill has set his sights on veterans of Iraq and Afghanistan to fill these roles. Ironically, Hill points to “coping skills” as a main reason. “A lot of them know how to operate under stress. All of them know how to take orders,” Hill said. “We want to get the best of the best, and bring them in here, and give them a home, and allow them to continue to serve”. Other departments across the country - such as the City of Austin Police Department and the Webb County Sheriff’s Office, both in Texas; the Denver Police Department in Colorado; the Hillsborough County and Orange County sheriff’s offices in Florida; and the Tucson Police Department in Arizona - have initiated similar efforts.
The correlation between the mental baggage of war, the increased hiring of military combat veterans as police officers, and an observable escalation of aggressive and violent police brutality is difficult to ignore. Police departments have screening processes, but many are lacking. The lingering effects from being in a war zone are unquestionable, and signs and symptoms which often are suppressed during “downtimes” tend to surface and intensify under distress - a common occurrence for police officers."
OK, this militarization thing has gone too far

Rise of the Warrior Cop, by Radley Balko.:
The Economics of Police Militarism
Two crucial battles broke out in Ferguson, Missouri, this week. The first began with the public airing of sorrow and rage after the death of the eighteen-year-old Michael Brown, who was shot by a police officer, on Canfield Court, in the St. Louis suburb, at 2:15 P.M. last Saturday. Then came the local law enforcement’s rejoinder to the early round of protests. Officers rolled in with a fleet of armored vehicles, sniper rifles, and tear-gas cannisters, reinserting the phrase “the militarization of policing” into the collective conscience. The tactical missteps by the town’s police leadership have been a thing to behold. (They’re also to be expected; anyone doubting as much should pick up Radley Balko’s “The Rise of the Warrior Cop.”)
How to End Militarized Policing
In the last week, the ACLU, Color of Change and even libertarian Senator Rand Paul have demanded that militarized policing in the United States be dialed back. While it is essential that major reductions in the high-tech military presence of police be enacted, real changes in the way communities of color are policed require much deeper shifts in the core mission and function of American police.

How Not to Design a World Without Borders
LAGO AGRIO, Ecuador—Hitler was behind the wheel, racing through a blur of jungle toward Ecuador’s border with Colombia. Only when an immigration officer in green fatigues hurried out from a checkpoint, yelling, did Hitler pump the brakes. The policeman asked if we wanted our passports stamped, and all four of us in the truck—an American, a Dane, a Colombian, and an Ecuadorian—declined. With that, the official waved goodbye and we lurched onward to Colombia.
