US Army’s UCP camouflage pattern “makes soldiers more visible, not less”

Filed under: Military, Technology, USA — Tags: , , , — Nicholas @ 09:06

As I mentioned briefly last week, the US Army is abandoning their most recent camouflage patterned combat uniforms:

The United States military is abandoning its recently-adopted pixelated camouflage uniforms, according to articles this week in The Daily as well as Stars and Stripes.

The drab grey digital pattern, known as the Universal Camouflage Pattern (UCP), will be discarded after only eight years following mounting evidence that the colour scheme makes soldiers more visible, not less.

The articles pull few punches in their appraisal of the move to adopt the pattern in 2004.

“Army brass interfered in the selection process, choosing looks and politics over science,” reports Stars and Stripes, the official newspaper of the United States armed forces.

And while the Pentagon spent $5 Billion on the much-heralded uniforms, some of the earliest attempts to conceal soldiers on the battlefield were considerably less expensive.

The This is War blog has a discussion of the development of camouflage over the last century and a half.

US Army reluctantly admits USMC did better

Filed under: Military, Technology, USA — Tags: , , , , , — Nicholas @ 09:06

In developing camouflage, that is:

The U.S. Army has decided to scrap its digital pattern camouflage combat uniforms for the more effective, but more expensive, MultiCam. In the last decade, both the army and marines adopted new, digital, camouflage pattern field uniforms. But in Afghanistan, U.S. soldiers noted that the marine digital uniforms (called MARPAT, for Marine Pattern) were superior to the army UCP (Universal Camouflage Pattern). There’s been growing dissatisfaction with UCP, and it has become a major issue because all the infantry have access to the Internet, where the constant clamor for something better than UCP forced the army to do something. This is ironic because UCP is a variant of MARPAT, but a poor one, at least according to soldiers who have encountered marines wearing MARPAT. Even more ironic is that MARPAT is based on research originally done by the army. Thus some of the resistance to copying MARPAT is admitting the marines took the same research on digital camouflage, and produced a superior pattern for combat uniforms.

A digital camouflage pattern uses “pixels” (little square or round spots of color, like you will find on your computer monitor if you look very closely), instead of just splotches of different colors. Naturally, this was called “digital camouflage.” This pattern proved considerably more effective at hiding troops than older methods. For example, in tests, it was found that soldiers wearing digital pattern uniforms were 50 percent more likely to escape detection by other troops, than if they were wearing standard green uniforms. What made the digital pattern work was the way the human brain processed information. The small “pixels” of color on the cloth makes the human brain see vegetation and terrain, not people. One could provide a more technical explanation, but the “brain processing” one pretty much says it all.

The US Air Force faces its toughest opponents: the lobbyists

Filed under: Military, Politics, Technology, USA — Tags: , , , — Nicholas @ 08:54

In a stunning outbreak of common sense, the USAF cancelled an order for an expensive UAV because it wasn’t as effective at the intended task as other methods. Battle would soon be joined with the fearsome lobbyists and their congressional minions:

Earlier this year, the U.S. Air Force cancelled existing orders for the RQ-4 Global Hawk UAV and withdrew 18 from service. The Global Hawk manufacturer (Northrop Grumman) unleashed their lobbyists and political supporters on the air force, demanding an explanation for (and reversal of) the decision. The air force responded that the RQ-4 was too expensive and the manufacturer too unreliable. Moreover, reconnaissance mission requirements had changed with the withdrawal from Iraq. High altitude, long duration missions were not needed as much. And those that were needed were better served by using the smaller and cheaper Reaper. Missions normally carried out by the RQ-4 were now handled more efficiently and cheaply by the U-2, which could carry more sensors to higher altitudes. Northrop Grumman insisted it could mount any U-2 sensors on an RQ-4. The air force replied that this had not been their experience. Northrop Grumman would offer to make modification which often went way over budget, took longer than specified and often didn’t work. The air force had been burned once too often by Northrop Grumman when it came to upgrades and fixes on the RQ-4.

[. . .]

Increasingly over the last decade, the air force and the manufacturer of the RQ-4 found themselves feuding over design, cost, and quality control issues. The latest issue was the unreliability of the new Block 30 models. This renewed Department of Defense threats to cancel the program. But Northrop Grumman lobbyists have made sure the key members of Congress knew where Global Hawk components were being built and how many jobs that added up to. While that delayed the RQ-4 Block 30 cancellation it did not stop it. The air force was placated for a while when Northrop Grumman fixed some of the problems (some of which the manufacturer said don’t exist, or didn’t matter). The Block 30 was supposed to be good to go, but the air force was not convinced and decided that Block 30 was just more broken promises. Congress was also tired of all the feuding and being caught between Northrup lobbyists and exasperated air force generals. Then there was politician’s decision to cut the defense budget over the next decade. Something had to go.

Meanwhile, the manned U-2 has continued to operate as expected and, despite its age, with predictable costs. Moreover, the U-2 carries a larger load than the RQ-4 and that means it can do more when it is up there. The U-2 also has its supporters in Congress. So the RQ-4 took a hit so the popular U-2 could keep flying for another decade or so.

[. . .]

There has been plenty of competition for RQ-4 work. In addition to the manned U-2, there is a longer (42 hours) endurance version of the five ton Reaper as well as the jet powered version of the Reaper called Avenger. This aircraft can do 85 percent of what the RQ-4 can, but costs half as much. Moreover, the Avenger is 29 percent faster, although it only has endurance of 20 hours, compared to 35 for the RQ-4. Most importantly, the Avenger and Reaper come from a manufacturer (General Atomics) that has been much more dependable than Northrop Grumman.

The “JesusPhone” turns five

Filed under: Media, Technology — Tags: , , — Nicholas @ 08:32

At The Register, Tony Smith looks back on five years of Apple’s iPhone phenomenon:

The iPhone first went on sale five years ago this week and it has already clocked up more than $150 billion in revenues — more than the annual GDP of Hungary — for Apple.

More than 250 million iPhones have been sold since 29 June 2007, the day over-the-counter sales began in the US, almost six months after its January 2007 launch.

That’s just the hardware, of course. Apple takes a 30 per cent cut of the purchase price of ever app downloaded through the iTunes App Store, and with well over 30 billion apps downloaded since the app shop went online on 10 July 2008.

[. . .]

The original iPhone, lest we forget, was a 2G device with GSM/Edge data connectivity. Its 16 bundled apps — it couldn’t run third-party native software, only JavaScript-coded “web apps” in its browser — ran on a 400MHz Samsung ARM11-based S3C6400 CPU and were presented on a 3.5in, 320 x 480 display.

There was no external storage — there still isn’t — and the battery was tightly integrated into the casing — it still is. It has a 2Mp camera and 4-16GB of on-board Flash storage.

But the iPhone introduced the world to smooth touchscreen operation, its capacitive panel outclassing the less sensitive resistive screens commonplace at the time. Likewise, it introduced roll, pitch and yaw detecting accelerometers, now found on every smartphone. Likewise Wi-Fi.

Railway engineering, 1947 style

Filed under: Britain, History, Railways, Technology — Tags: , , — Nicholas @ 00:03

London, Midland & Scottish Railway documentary that shows the relaying of St. Pancras Junction with prefabricated trackwork, along with the associated changes to the signalling system.

What struck me while watching this was the ages of most of the track crew: I’d have expected them to be a bunch of teens-to-early 20’s guys, but there are a lot of old gaffers still doing the heavy lifting here. Oh, and of course the work clothes: caps, hats, jackets, and braces. Not a hard hat or much in the way of obvious safety gear in sight. They may or may not have been better men in those days, but they earned their aches and pains honestly.

Microsoft Surface: “Lacking a physical product to test, all we can do is talk bollocks based on conjecture”

Filed under: Humour, Technology — Tags: , , — Nicholas @ 10:09

While I’ve been avoiding tablet computers, having an actual keyboard that can attach to a tablet makes it more like something I might be able to find a use for. In The Register, Alistair Dabbs explains why he’s already very fond of the announced-but-not-available-yet Microsoft Surface:

I don’t wish to suggest that Microsoft Surface is truly vapourware, but surely it’s suspicious that it’s announcing a product that no one’s going to be able to buy for half a year.

One supposes that Microsoft intends to create a buzz and get us talking about their forthcoming (new) foray into tablet computers. Yet the problem with jumping the gun — apart from the ‘false start’ accusations that lead on from this metaphor — is that commentators are left with a void to fill. Lacking a physical product to test, all we can do is talk bollocks based on conjecture.

This, as you know, is my specialty.

First, let me say that I don’t care a hoot about the provenance of the name ‘Surface’ — ho-ho, it used to be a table, so fucking what? Making fun of a name tells us nothing about the product.

Take ‘Metro’.

“We call it Metro because it’s modern and clean.” Oh, and here’s me thinking they called it Metro because it’s populated by young Algerians brandishing flick-knives and smells of wee. It’s just a word to put on the packaging and its actual meaning has no significance. After all, what does the word ‘pod’ have to do with playing MP3 files?

Even Mother Jones is coming around on genetically modified crops

Filed under: Environment, Food, Science, Technology — Tags: — Nicholas @ 10:11

Sarah Zhang points out that people who want less damage to the environment should support GM technology in farming:

Genetically modified Bt crops get a pretty bad rap. The pest-killing Bacillus thuringiensis (Bt) bacteria protein these plants are bioengineered to make has been accused of harming monarch butterflies, honey bees, rats, and showing up in the blood of pregnant women.

Just one problem: None of that is true. (Click on any of those links to see a scientific refutation of each claim.) Seven independent experts in genetically modified crops I spoke to all confirmed that the science shows Bt crops to be safer than their alternative: noxious chemical insecticides.

[. . .]

But just as we do not blame a murder on, say, a knife, Bt technology is not to blame for the ills of industrial agriculture. After all, knives are pretty handy in the kitchen when we use them properly. Even critics will acknowledge that Bt crops have led to a sharp decrease in insecticide use, which is a huge net positive for the environment. Broad spectrum chemical insecticides kill often and kill widely, wiping out “natural enemies” that are helpful pest-eating critters like spiders. A massive 20-year study just published in the journal Nature found that using Bt cotton in China to control cotton bollworms closely tracked with a rebound in natural enemy populations, which in turn keep out secondary pests like aphids that usually proliferate when chemical insecticides kill the bollworms.

If that last sentence sounds complicated, it is. Integrated pest management is about recognizing the interconnected complexity of these ecosystems of plants and all the insects living on them. The Nature study found that pest control through Bt cotton even had spillover benefits to the non-Bt soybeans growing around them. Natural enemies like ladybugs, spiders, and lacewings keep pests unaffected by Bt at bay. “Maintaining the biological control agents we already have is one of the cornerstones of integrated pest management,” says William Hutchison, an entomologist at the University of Minnesota. In addition, a 2010 study by Hutchison in Science (PDF) showed that American farmers of non-Bt corn actually reaped two-thirds of the economic benefit (read: additional profit) from nearby Bt-related pest suppression.

New proposal: HTTP Error Code 451 to indicated “content censored by authorities”

Filed under: Government, Law, Liberty, Media, Technology — Tags: , , — Nicholas @ 14:04

Kevin Fogarty at PC World looks at a new HTTP error code proposal:

A high-profile Google developer has proposed that the Internet Engineering Task Force (IETF) that it endorse a new HTTP Status Code to warn readers the page they’re looking for has been censored by authorities, according to TheVerge.

Tim Bray, who co-invented XML and works as Android Developer Advocate at Google, is submitting a proposal that pages censored by someone other than the owner of the site or of the user’s local network display the error code “451 Unavailable for Legal Reasons.”

The number in the code is a reference to Ray Bradbury’s “Farenheit 451,” which describes a dystopian future in which book burnings and the censorship of unacceptable material is routine. Google already highlights search terms that may return censored results, in some countries.

Speculation on the intended mission of the X-37B

Filed under: China, Space, Technology, USA — Tags: , , , , — Nicholas @ 12:24

A blog post at New Scientist compares the achievement of the Chinese space program, which just successfully placed three astronauts aboard the ISS and the highly mysterious X-37B spaceplane which just completed a 469-day mission:

China’s space agency took the plaudits for successfully docking its crewed Shenzhou-9 spacecraft with its orbiting lab Tiangong-1 today, but the feat was slightly overshadowed by the weekend landing of the US X-37B spaceplane, which after a record-breaking orbital flight of 469 days showed just how far China has to go to catch up with advanced spacefaring nations.

At around noon local time, the Beijing Aerospace Control Centre relayed live pictures of Shenzhou-9’s docking on state broadcaster China Central Television. The space capsule held off at a distance of 62 kilometres from Tiangong-1 before making its docking approach just before 2pm — and once the crew had manually locked on to the latter’s cruciform docking target it took only eight minutes to latch the spacecraft together safely.

[. . .]

This Boeing-built spaceplane, roughly one quarter the size of the space shuttle, is equally mysterious. It flies to orbit on a regular rocket and when there deploys a solar array that gives its sensors the power they need for extended missions. It also has enough propellant to fire thrusters that make small changes to its orbit in a bid to foil surveillance. The vehicle re-enters the atmosphere just like the shuttle but lands entirely autonomously, making it a space drone.

At no point has the USAF revealed the craft’s purpose: in addition to spacecraft surveillance, it could deploy a robot that repairs (or disables) satellites in orbit, say some, while at the darker end of the spectrum of possibilities — it was a DARPA project in its early days — it could carry a warhead, using its drone homing capability to provide surprise precision strike from orbit.

Clang!

Neal Stephenson wants your money to help him create a realistic sword fighting game:

Hi, Neal Stephenson here. My career as an author of science and historical fiction has turned me into a swordsmanship geek. As such, I’m dissatisfied with how swordfighting is portrayed in existing video games. These could be so much more fun than they are. Time for a revolution.

In the last couple of years, affordable new gear has come on the market that makes it possible to move, and control a swordfighter’s actions, in a much more intuitive way than pulling a plastic trigger or pounding a key on a keyboard. So it’s time to step back, dump the tired conventions that have grown up around trigger-based sword games, and build something that will enable players to inhabit the mind, body, and world of a real swordfighter.

Yet another scare “study” about teens and video gaming

Filed under: Gaming, Media, Technology — Tags: , , — Nicholas @ 12:00

Martin Robbins in the Guardian on another “study” linking teenagers who play video games to negative results:

Not that the ‘research’ cited says anything about violent video games to begin with. BAAM conducted a survey of 204 parents of children aged nine to eighteen, asking about their use of computer games: anything from Tetris to GTA IV via SimCity. This produced the following results:

    “Forty-six per cent said their sons or daughters had become ‘less co-operative’ since they started playing video games. Forty-four per cent said they were more ‘rude or intolerant towards others’, 40 per cent said they were more impatient, 36 per cent reported an increase in ‘aggressive behaviour’, 29 per cent cited more mood swings and 26 per cent said their offspring had become more reclusive.”

26% of parents thought their teen offspring had become more reclusive in the years since they started playing video games. No doubt pedantic nay-sayers will whine on about the other SEVENTY-BLOODY-FOUR PER CENT of kids who either didn’t become more reclusive or became less reclusive, or ask how ‘reclusive’ is even defined or measured in the first place; but if that incredible correlation doesn’t persuade you, well then by golly-gosh I don’t know what will.

Even the most ‘persuasive’ of those figures stands at just 46%. That, astonishingly, is the proportion of parents who think their teenaged children are becoming less cooperative with time. This is put down to video games, rather than something silly, like… oh I don’t know, maybe the fact that they’re teenagers?! 46% is a shocking figure only in the sense that I’m shocked it’s only 46%. Perhaps video games actually make kids more cooperative? We have no way of knowing, because there doesn’t seem to have been any effort made to survey kids who don’t play video games as a control group.

Scattering that “social” pixie dust on mobile apps

Filed under: Media, Technology — Tags: , , , , — Nicholas @ 09:37

In the Guardian Technology section, Frédéric Filloux attempts to disabuse mobile developers about one of the “rules” for mobile apps:

Today’s hype leaves no other option but making an application as “social” as possible. This being the certitude du jour, allow me to think differently.

True, some apps are inherently social: when it comes to rating a product or a service, the “crowd factor” is critical. Beyond that, it should be a matter of personal choice — an antinomic notion to today’s the “Social” diktat. When you sign up to Spotify, the default setting is to share your musical taste with your Facebook friends and to suffer theirs. I can’t stand such obligation: I quickly dumped the application and cancelled my account.

The social idea’s biggest mistake is the belief in a universal and monolithic concept everyone is supposed to be willing to embrace with a similar degree of scope and enthusiasm. That’s a geeky, super-cartesian, Zuckerberg-esque view of society. Among my friends, some like opera (the singing, not the browser), others prefer heavy metal and I’m more into jazz tunes; some are tech-minded like me, others are more inclined towards literature. When it comes to sharing news, I tend to be naturally selective about the people I send a link to: I don’t want to swamp everyone with stuff they don’t care about. I might be wrong, but this is the way I see the social cyberspace: segmented and respectful of each other.

So, mobile app developers, if you find yourself trying to force-fit social features into a Solitaire app, think again.

Stuxnet, Duqu, and Flame: joint US-Israeli projects

Filed under: Middle East, Military, Technology, USA — Tags: , , , , , — Nicholas @ 09:02

The US and Israeli governments have admitted that the Stuxnet, Duqu, and Flame malware infections were joint efforts:

American and Israeli officials have finally confirmed that the industrial grade Cyber War weapons (Stuxnet, Duqu and Flame) used against Iran in the last few years were indeed joint U.S.-Israel operations. No other details were released, although many more rumors are now circulating. The U.S. and Israel were long suspected of being responsible for these “weapons grade” computer worms. Both nations had the motive to use, means to build and opportunity to unleash these powerful Cyber War weapons against Iran and other that support terrorism.

The U.S. Department of Defense had long asked for permission to go on the offensive using Cyber War weapons. But the U.S. government regularly and publicly declined to retaliate against constant attack from China, mainly because there were fears that there could be legal repercussions and that weapons used might get out of control and cause lots of damage to innocent parties.

Iran turned out to be another matter. Although not a serious Cyber War threat to the United States, Iran was trying to build nuclear weapons and apparently Israel had already been looking into using a Cyber War weapon to interfere with that. Given the nature of these weapons, which work best if the enemy doesn’t even know they exist, don’t expect many details to be released about this Cyber War program. What is known is that the Cyber War weapons unleashed on Iran were designed to concentrate only on very specific targets. So far, only three weapons that we know of have been used. One (Stuxnet) was designed to do damage to one specific facility, the plant where Iran produced nuclear fuel for power plants, and atomic weapons. That one worked. The other two (Duqu and Flame) were intelligence collection programs. They also apparently succeeded, remaining hidden for years and having lots of opportunity to collect enormous quantities of valuable data.

The US military’s SF research emporium

Filed under: Media, Military, Science, Technology, Weapons — Tags: , , , , , , — Nicholas @ 08:18

John Turner sent me a link to this amusing little survey of what the US military’s R&D organization is willing to admit they’re working on and how it might be helpful in case of an alien invasion:

As summer blockbuster season kicks into high gear, big-budget action movies like The Avengers, Battleship, and Prometheus remind us that there’s one thing that unites Americans: Our shared fear of an alien attack. They also remind us that when the invading space fleet arrives, humanity is not going to surrender without a fight to our intergalactic invaders. Instead, we will band together to fight off their incredibly advanced weaponry with our … well, with what, exactly? Are we really ready to battle our would-be alien overlords?

Luckily, the Pentagon’s Defense Advanced Research Projects Agency, better known as DARPA, as well as some of the world’s largest weapons manufacturers, are dreaming up the weapons of the future today. With the help of everything from lasers on jets to hypersonic planes to invisibility cloaks, we just might be able to make the battle for Earth a fair fight. You may think we’re joking, but why else would NASA be uploading The Avengers to the International Space Station if not as a training manual? Here’s a look at some of the most space-worthy inventions being cooked up now.

An issue for any unmanned, armed vehicle (whether land, sea or air) is the security of communications from the controller to the vehicle. Recent use of such devices has almost always been in combat against relatively low-tech opponents who did not have jamming or hacking capabilities (although the UAV forced down in Iran may signal the end of the easy period for combat UAVs). Earlier discussions of benefits and drawbacks to unmanned fighters are here, here, and here.

Old worry: the “digital divide”

Filed under: Media, Technology, USA — Tags: , , , , — Nicholas @ 00:06

The good news is that the much-feared “digital divide” between the rich and poor never came to pass. Now the worry is rather different:

Remember the “digital divide”? Back in the 1990s, the problem was that poor people did not have enough access to computers and the Internet. Today the problem is that they have too much access. Evidently the digital divide has given way to the “time-wasting gap.” I shit you not. The New York Times reports that bridging the digital divide “created an unintended side effect, one that is surprising and troubling to researchers and policy makers and that the government [naturally] now wants to fix”: “As access to devices has spread, children in poorer families are spending considerably more time than children from more well-off families using their television and gadgets to watch shows and videos, play games and connect on social networking sites.” Silly lower classes! Don’t they realize this wonderful new technology is for self-improvement, not for pleasure? Something must be done
