Hyperlocal manufacturing: fabrication factory in a shipping container

It’s amazing what you can cram into a shipping container: a solar power generator, an internet cafe, a data centre… or a self-contained tooling workshop and fabrication unit [via GlobalGuerrillas – beware dodgy pop-ups on the linked page]:

The MPH was developed when the army realized that the easiest way to get the many rarely requested, but vital, replacement parts to the troops, was to manufacture the parts in the combat zone. In short order, this led to the construction of a portable parts fabrication system, called MPH, that fit into a standard 8x8x20 foot shipping container. The original version used two containers, but smaller equipment and more powerful computers eventually made it possible to use one container.

As John Robb and others have pointed out, this is a blueprint for hyperlocal manufacturing… though to make it economically practical you’re going to have to shave down the construction costs from the bloated levels of military contracting:

There are four MPH systems in service, two of them in Afghanistan. A fourth is being built, at a cost of $1.5 million.

Ouch. What do you actually need? If you’re going local, you just need a space the same size as a shipping container; should be a stuffed animal that’ll do the job. A fast broadband connection will stand in for the military satellite link (assuming you’re operating in an urban area); speed probably isn’t too crucial with non-military applications, so you might be able to cantenna yourself into a convenient local wireless node for big savings. Then you need CNC machines and raw materials; the former can probably be bought up pretty cheap from bankrupt stock (hell, you might not even need to move the kit if it’s still sat in a disused factory unit – two birds, one stone), and the latter scraped up from salvage and reclamation…

Anyone fancy running the numbers on this?

Nice people acquire power and are then corrupted by it

Once again, research results seem to reinforce the oldest aphorisms in the book… which would be more gratifying, perhaps, if they weren’t the aphorisms we tell to commiserate over the fundamental brokenness of the social and political systems we inhabit. It turns out that nice people are far more likely than nasties to ascend to a position of power and authority… but once they get there, that power corrupts them, and they become reckless, selfish and unpleasant [via BigThink]. Who knew?

“It’s an incredibly consistent effect,” Mr. Keltner says. “When you give people power, they basically start acting like fools. They flirt inappropriately, tease in a hostile fashion, and become totally impulsive.” Mr. Keltner compares the feeling of power to brain damage, noting that people with lots of authority tend to behave like neurological patients with a damaged orbito-frontal lobe, a brain area that’s crucial for empathy and decision-making. Even the most virtuous people can be undone by the corner office.

Why does power lead people to flirt with interns and solicit bribes and fudge financial documents? According to psychologists, one of the main problems with authority is that it makes us less sympathetic to the concerns and emotions of others. For instance, several studies have found that people in positions of authority are more likely to rely on stereotypes and generalizations when judging other people. They also spend much less time making eye contact, at least when a person without power is talking.

Turns out it’s all about self-justification:

In a recent study led by Richard Petty, a psychologist at Ohio State, undergraduates role-played a scenario between a boss and an underling. Then the students were exposed to a fake advertisement for a mobile phone. Some of the ads featured strong arguments for buying the phone, such as its long-lasting battery, while other ads featured weak or nonsensical arguments. Interestingly, students that pretended to be the boss were far less sensitive to the quality of the argument. It’s as if it didn’t even matter what the ad said—their minds had already been made up.

This suggests that even fleeting feelings of power can dramatically change the way people respond to information. Instead of analyzing the strength of the argument, those with authority focus on whether or not the argument confirms what they already believe. If it doesn’t, then the facts are conveniently ignored.

Sound familiar? As in, remind you of pretty much every director or upper-echelon manager you’ve ever worked for, anywhere? Yeah, me too.

Now, how much of that is due to a Stanford Prison Experiment type of situation, i.e. people playing up to an arbitrary role as it is defined in the collective subconscious (we know bosses act like ass-hats, so when we’re told to play the boss, we act like an ass-hat), and how much of it is due to some genuine qualitative difference in perception that comes from being elevated into a more exclusive and powerful cadre or subsection of a social group?

[ The irony of this article appearing in the Wall Street Journal is almost palpable. I can just imagine loads of investment bankers reading it, tutting quietly and shaking their heads, doubtless reminded of someone that little higher up on the pyramid than themselves. Oh, how the mighty have fallen, hmm? ]

From carjack to carhack

As if you didn’t have enough things to worry about when you’re driving… researchers have demonstrated some rather worrying security holes that could allow an attacker to PWN your car’s onboard computer systems by spoofing the signals from the wireless tyre pressure sensors [via George Dvorsky]:

… previous experiments showed what could be done with a physical connection to a vehicle’s computer. The new work by teams from the University of South Carolina and Rutgers tried a different tack: spoofing the wireless sensors in wheels used by tire pressure monitoring systems, required in all new U.S. vehicles since 2008.

The researchers didn’t find a wide-open door so much as the security employed by a 1920s speakeasy: once they learned the secret knock, the unidentified test car’s controls let them in no questions asked. The team sent fake warning messages from 40 meters away, and in another experiment, got the test car to flash a warning that a tire had lost all pressure while beaming the signal from another car as both drove 68 mph.

Because each sensor uses a unique ID tag, it was also possible to track specific vehicles, in a way that would be far less noticeable than roadside cameras.

The hacked car usually reset its warnings after the spoofed messages stopped. But after two days of tests, the electronic control unit for the tire monitors fell off its twig and had to be replaced by a dealer. The researchers note that it took several hours of graduate-level engineering to devise their tools and crack into the monitors, but that the actual technology for doing so cost about $1,500.

Buying off-the-shelf kits to accomplish this sort of hack will be as easy as buying an ATM credit card skimmer or a few hours of run-time on a botnet; it’s just chips and code, after all. And now, would the congregation please join with me in chanting the votive mantra of Futurismic: Everything Can And Will Be Hacked.

Ice Fracture Explorer: theoretical model for a mission to Europa

Joseph Shoer of Quantum Rocketry doesn’t post all that often, but every now and again he puts out a gem. Here he is imagining what you’d need to do to put together a robotic mission to explore Europa, the Jovian moon that’s mostly ocean with a thick icy crust, complete with little diagrams of what the modules might look like:

As Jupiter rises overhead, its tides will pull apart the two sides of the ice fracture. The IFE will be suspended in the middle as the crack opens, with nothing below it until the ocean 1-10 km down! At this point, the IFE will drop its deflated cushions and begin to deploy a smaller penetrator vehicle from its underside. The penetrator is a small, two-stage vehicle with two instrument packages, a hard-shell body, and a data line connecting it to the IFE’s main bus.

Pure hard-SF space geekery of the best type. As Shoer points out, manned missions to Europa are pretty much a non-starter; even if we could get people there, the radiation would roast them pretty quickly. But throw some transhuman moravec explorers into the mix, and you’ve got the start of a great story…
