UAVs move closer to the front rank of US Navy assets

Strategy Page on the progress of the X-47B UAV:

The U.S. Navy X-47B UCAV (unmanned combat air vehicle) made its first catapult launch on November 29th, 22 months after its first flight. This launch was not from a carrier, but an airfield built to the same size as a carrier deck and equipped with a catapult. This first launch was to confirm that the X-47B could handle the stress of a catapult launch. Another X-47B has been loaded onto the deck of a carrier, to check out the ability of the UCAV to move around the deck. If all goes well, the first carrier launch of an X-47B will take place next year, along with carrier landings. Last year the navy tested its UCAV landing software, using a manned F-18 for the test, landing it on a carrier completely under software control.

It was four years ago that the navy rolled out the first X-47B, its first combat UAV. This compact aircraft has a wingspan of 20 meters (62 feet, and the outer 25 percent folds up to save space on the carrier). It carries a two ton payload and will be able to stay in the air for twelve hours. The U.S. is far ahead of other nations in UCAV development, and this is energizing activity in Russia, Europe and China to develop similar aircraft. It’s generally recognized that robotic combat aircraft are the future, even though many of the aviation commanders (all of them pilots) wish it were otherwise. Whoever gets there first (a UCAV that really works) will force everyone else to catch up, or end up the loser in their next war with someone equipped with UCAVs.

The U.S. Navy has done the math and realized that they need UCAVS on their carriers as soon as possible. The current plan is to get these aircraft into service six years from now. But there is an effort to get the unmanned carrier aircraft into service sooner than that. The math problem that triggered all this is the realization that American carriers had to get within 800 kilometers of their target before launching bomber aircraft. Potential enemies increasingly have aircraft and missiles with range greater than 800 kilometers. The navy already has a solution in development; the X-47B UCAS has a range of 2,500 kilometers

The feudal technopeasant internet

Filed under: History, Liberty, Technology — Tags: , , , , , , — Nicholas @ 11:20

Bruce Schneier on the less-than-appealing state of user security in today’s internet:

It’s a feudal world out there.

Some of us have pledged our allegiance to Google: We have Gmail accounts, we use Google Calendar and Google Docs, and we have Android phones. Others have pledged allegiance to Apple: We have Macintosh laptops, iPhones, and iPads; and we let iCloud automatically synchronize and back up everything. Still others of us let Microsoft do it all. Or we buy our music and e-books from Amazon, which keeps records of what we own and allows downloading to a Kindle, computer, or phone. Some of us have pretty much abandoned e-mail altogether … for Facebook.

These vendors are becoming our feudal lords, and we are becoming their vassals. We might refuse to pledge allegiance to all of them — or to a particular one we don’t like. Or we can spread our allegiance around. But either way, it’s becoming increasingly difficult to not pledge allegiance to at least one of them.

Feudalism provides security. Classical medieval feudalism depended on overlapping, complex, hierarchical relationships. There were oaths and obligations: a series of rights and privileges. A critical aspect of this system was protection: vassals would pledge their allegiance to a lord, and in return, that lord would protect them from harm.

Of course, I’m romanticizing here; European history was never this simple, and the description is based on stories of that time, but that’s the general model.

And it’s this model that’s starting to permeate computer security today.

We’re from the ITU and we’re here to “fix” your internet

Filed under: Bureaucracy, Liberty, Media, Technology — Tags: , , , , , — Nicholas @ 10:32

At Techdirt, Nick Masnick recounts some of the wonderful things the International Telecommunications Union would like to “help” regarding that pesky “internet” thing:

We’ve been talking about the ITU’s upcoming World Conference on International Telecommunications (WCIT) for a while now, and it’s no longer “upcoming.” Earlier today, the week and a half session kicked off in Dubai with plenty of expected controversy. The US, the EU and now Australia have all come out strongly against the ITU’s efforts to undermine the existing internet setup to favor authoritarian countries or state-controlled (or formerly state-controlled) telcos who want money for internet things they had nothing to do with. The BBC article above has a pretty good rundown of some of the scarier proposals being pitched behind closed doors at WCIT. Having the US, EU and Australia against these things is good, but the ITU works on a one-vote-per-country system, and plenty of other countries see this as a way to exert more control over the internet, in part to divert funds from elsewhere into their own coffers.

Hamadoun Toure, secretary-general of the ITU, keeps trying to claim that this is all about increasing internet access, but that’s difficult to square with reality:

    “The brutal truth is that the internet remains largely [the] rich world’s privilege, ” said Dr Hamadoun Toure, secretary-general of the UN’s International Telecommunications Union, ahead of the meeting.

    “ITU wants to change that.”

Of course, internet access has already been spreading to the far corners of the planet without any “help” from the ITU. Over two billion people are already online, representing about a third of the planet. And, yes, spreading that access further is a good goal, but the ITU is not the player to do it. The reason that the internet has been so successful and has already spread as far as it has, as fast as it has, is that it hasn’t been controlled by a bureaucratic government body in which only other governments could vote. Instead, it was built as an open interoperable system that anyone could help build out. It was built in a bottom up manner, mainly by engineers, not bureaucrats. Changing that now makes very little sense.

Canada is also on the record as being against the expansion of the ITU’s role.

Canada will look to prevent governments from taking more power over the Internet when governments sit down for 12 days of negotiations on the future of the Internet next week, but the government didn’t say Thursday where it stands on a contentious proposal that could see users pay more for online content.

Canada’s position going into the World Conference on International Telecommunications (WCIT) mirrors a number of Western allies in opposing having governments control how the Internet functions, leaving it to the current mix of public and private sector actors, according to documents released to Postmedia News under access to information laws. That stance is in contrast to proposals from some of the 193 members of the International Telecommunications Union, such as Russia, that want greater control over the Internet — more so than they already have in some cases — including more powers to track user identities online.

The meeting in Dubai will determine whether the ITU, an arm of the United Nations, will receive broad regulatory powers to set rules of road in cyberspace. The potential to centralize control over the Internet into the hands of governments has some users and hacktivists concerned that freedoms online would be crushed should a new binding international treaty change the status quo for how telecommunications companies interact across borders.

Can we bury iTunes yet?

Filed under: Media, Technology — Tags: , , , — Nicholas @ 10:42

In Slate, Farhad Manjoo calls for the abolition of the worst carbuncle on Apple’s escutcheon:

iTunes 11 did not arrive on time. Apple originally promised to deliver the next version of its ubiquitous music-management program in October. Last month, though, the company announced that the release would slip to November, because the company needed “a little extra time to get it right.” This week the Wall Street Journal, citing “people who have seen it,” reported that the real cause was “engineering issues that required parts to be rebuilt.”

I suspect both those explanations are euphemisms for what’s really happening in Cupertino. I picture frazzled engineers growing increasingly alarmed as they discover that the iTunes codebase has been overrun by some kind of self-replicating virus that keeps adding random features and redesigns. The coders can’t figure out what’s going on — why iTunes, alone among Apple products, keeps growing more ungainly. At the head of the team is a grizzled old engineer who’s been at Apple forever. He’s surly and crude, always making vulgar jokes about iPads. But the company can’t afford to get rid of him — he’s the only one who understands how to operate the furnaces in the iTunes boiler room.

Then one morning the crew hears a strange clanging from iTunes’ starboard side. Scouts report that an ancient piston — something added for compatibility with the U2 iPod and then refashioned dozens of times — has been damaged while craftsmen removed the last remnants of a feature named Ping whose purpose has been lost to history. The old engineer dons his grease-covered overalls and heads down to check it out. Many anxious minutes pass. Then the crew is shaken by a huge blast. A minute later, they hear a lone, muffled wail. They send a medic, but it’s too late. The engineer has been battered by shrapnel from the iOS app management system, which is always on the fritz. His last words haunt the team forever: She can’t take much more of this. Too. Many. Features.

I use iTunes, but only because I need to back up my iPhone data … and nearly half the time, iTunes craps out on me and I have to go looking for fixes or work-arounds from Apple. Since I updated my iPhone to the most recent iOS version, I haven’t been able to sync with iTunes at all. Here’s hoping that the new version will fix that — and maybe, if we’re lucky, some other issues, too.

Update, 1 December: The update went well enough, but it still couldn’t contact the iTunes store or detect my iPhone. After a few minutes of looking through the Apple troubleshooting help pages, I reset the DNS cache and re-enabled iTunes to run in Administrator mode. That was enough to let it detect the iPhone and run a backup and re-synch.

Chinese aviators start carrier landing practice

Filed under: China, Military, Technology — Tags: , , , — Nicholas @ 09:52

Strategy Page updates us on the development of China’s aircraft carrier capabilities:

A Chinese aviator, flying a Chinese made J-15 fighter, made the first landing and takeoff from a Chinese aircraft carrier just two months after the ship was commissioned (on September 25th). The first Chinese aircraft carrier, the Liaoning is a 65,000 ton, 305 meter (999 feet) long ship that had spent over a year on sea trials. During that time Liaoning was at sea for about four months. This was all in preparation for flight operations. Last year China confirmed that the Liaoning will primarily be a training carrier. The Chinese apparently plan to station up to 24 jet fighters and 26 helicopters on the Liaoning and use the ship to train pilots and other specialists for four or more additional carriers.

Five years ago the Chinese Navy Air Force began training carrier fighter pilots (or “aviators” as they are known in the navy). In the past Chinese navy fighter pilots went to Chinese Air Force fighter training schools, and then transferred to navy flight training schools to learn how to perform their specialized (over open water) missions. Now, operating from carriers, and performing landings and take-offs at sea, has been added to the navy fighter pilot curriculum. The first class of carrier aviators has finished a four year training course at the Dalian Naval Academy. This included learning how to operate off a carrier, using a carrier deck mock-up on land. Landing on a moving ship at sea is another matter. The Russians warned China that it may take them a decade or more to develop the knowledge and skills needed to efficiently run an aircraft carrier. The Chinese are game and are slogging forward. The first landing and takeoff was apparently carried out in calm seas. It is a lot more difficult in rough weather (when the carrier is moving up and down and sideways a lot) and at night. The latter, called “night traps” is considered the most difficult task any aviator can carry out, especially in rough weather.

They also point out that the US Navy’s experiments with naval UAVs continue and are putting technological pressure on both Russia and China to do the same:

Over the last few years, the U.S. Department of Defense decided that the air force and navy be allowed to develop combat UAVs to suit their particular needs. The X-45 was meant mainly for those really dangerous bombing and SEAD missions. But the Pentagon finally got hip to the fact that the UCAV developers were coming up with an aircraft that could replace all current fighter-bombers. This was partly because of the success of the X-45 in rapidly reaching its development goals, and the real-world success of the Predator (in finding, and attacking, targets) and Global Hawk (in finding stuff after flying half way around the world by itself.)

The U.S. Navy expects UAVs to replace most manned aircraft on carriers and the Chinese are aware of that. So the age of manned aircraft operating from Chinese carriers may be a short one. Chinese engineers are well aware of automatic pilot software and how it works. Now they will have feedback from Chinese carrier pilots and be able to do what the Americans have done.

The usual caveats about UAVs in combat should be noted.

Anthropology and hacker culture

Filed under: Media, Technology — Tags: , , , , — Nicholas @ 11:56

Cory Doctorow on a new book by Biella Coleman called Coding Freedom: The Ethics and Aesthetics of Hacking:

[Coleman’s dissertation has been], edited and streamlined, under the title of Coding Freedom: The Ethics and Aesthetics of Hacking, which comes out today from Princeton University Press (Quinn Norton, also well known for her Wired reporting on Anonymous and Occupy, had a hand in the editing). Coding Freedom walks the fine line between popular accessibility and scholarly rigor, and does a very good job of expressing complex ideas without (too much) academic jargon.

Coding Freedom is insightful and fascinating, a superbly observed picture of the motives, divisions and history of the free software and software freedom world. As someone embedded in both those worlds, I found myself surprised by connections I’d never made on my own, but which seemed perfectly right and obvious in hindsight. Coleman’s work pulls together a million IRC conversations and mailing list threads and wikiwars and gets to their foundations, the deep discussion evolving through the world of free/open source software.

Tim Worstall: Cosmic fun-spoiler

Filed under: Economics, Space, Technology — Tags: , , , — Nicholas @ 11:42

Writing in The Register, Tim Worstall brings his evil economist gaze to the SF fan’s irrational belief that asteroid mining is the way of the future:

Isn’t it exciting that Planetary Resources is going to jet off and mine the asteroids? This is every teenage sci-fi geek’s dream, that everything we imbibed from Verne through Heinlein to Pournelle is going to come true!

But there’s always someone, isn’t there, someone like me, ready to spoil the party. The bit that I cannot get my head around is the economics of it: specifically, the economics of the mining itself.

In terms of the basic processing of what they want to do I can’t see a problem at all, just as all those authors those years ago could see how it could be done.

Asteroids come in several flavours, and the two we’re interested in here are the ice ones and the nickel iron ones. The icy rocks, with a few solar panels and that very bright 24/7 sunshine up there, can provide water. That’s the first thing we need in abundance if we’re going to get any number of people up off the planet for any appreciable amount of time. And we’d really rather not be sending the stuff up out of the Earth’s gravity well for them.

It’s also true that those nickel iron asteroids are likely to be rich in platinum-group metals (PGMs). They too can be refined with a bit of electricity, and they’re sufficiently valuable (say, for platinum, $60m a tonne, just as a number to use among friends) that we might be able to finance everything we’re trying to do by doing so.

All terribly exciting, all very space cadet, enough to bring tears to the eyes of anyone who ever learnt how to use a slide rule and, as the man said, once you’re in orbit you’re not halfway to the Moon, you’re halfway to anywhere.

Except I’m not sure that the numbers quite stack up here. I’m sure that the engineering is possible, I’m certain that it’s all worth doing and most certainly believe that we want to get up there and start playing around with other parts of the cosmos over and above Gaia. But, but…

Creating Aston Martin DB5s to blow up real good

Filed under: Media, Technology — Tags: , , , — Nicholas @ 11:40

3D printing to the (budget) rescue for 007:

Sean Connery first rocked the iconic James Bond Aston Martin DB5 in 1964’s Goldfinger. That vehicle made a reappearance in this year’s blockbuster Skyfall with Daniel Craig at the wheel.

Spoiler alert: Craig’s DB5 meets an untimely end involving flames. You can’t just take a priceless real DB5 and blow it up on film, so the filmmakers turned to a high-tech prop solution: 3D printing.

Voxeljet, a 3D printing company in Germany, created three 1:3 scale models of the rare DB5. Each model was made from 18 separate components that were assembled much like a real car. The massive VX4000 printer could have cranked out a whole car, but the parts method created models with doors and hoods that could open and close.

The Hall of Technical Documentation Weirdness returns

Darren Barefoot has revived the Hall of Technical Documentation Weirdness as a Pinterest site:

“Stop, criminal!”

Filed under: Law, Technology, USA — Tags: , , — Nicholas @ 09:46

Vague legal wording and fuzzy intent turn ordinary activities into crimes:

Are you reading this blog? If so, you are committing a crime under 18 USC 1030(a) (better known as the “Computer Fraud & Abuse Act” or “CFAA”). That’s because I did not explicitly authorize you to access this site, but you accessed it anyway. Your screen has a resolution of 1600×900. I know this, because (with malice aforethought) I clearly violated 18 USC 1030(a)(5)(A) by knowingly causing the transmission of JavaScript code to your browser to discover this information.

So we are all going to jail together.

That’s silly, you say, because that’s not what the law means. Well, how do you know what the law means? The law is so vague that it’s impossible to tell.

The CFAA was written in 1986. Back then, to access a computer, you had to have an explicit user account and password. It was therefore easy to tell whether access was authorized or not. But then the web happened, and we started accessing computers all over the world without explicit authorization.

So, without user accounts or other form of explicit authorization, how do we tell if access to a website is “authorized” or not?

Upgrading the Coyote

Filed under: Cancon, Military, Technology — Tags: , , , , — Nicholas @ 09:23

Strategy Page has a bit of Canadian content now and again:

Canada has ordered upgrades for another of its 66 LAV III wheeled armored vehicles. These 66 will be equipped for reconnaissance as was its predecessor the LAV II Coyote. This vehicle went to Afghanistan a decade ago and proved enormously useful by doing long range surveillance of Taliban and al Qaeda suspects. The Coyote reconnaissance system mounted on a wheeled armored vehicle. The recon gear consists of a nine meter (30 foot) telescoping mast that contains a Doppler radar, laser rangefinder, thermal imaging sensor and video camera. The mast mounted sensors can see clearly out to 15 kilometers and identify targets (day or night) for artillery or air attack. The radar can spot targets out to 24 kilometers, but can only distinguish vehicle types (wheeled, tracked) beginning at about 12 kilometers.

[. . .]

The Coyote was originally conceived as an inexpensive replacement for air reconnaissance. But the ability of a Coyote vehicle to stay in one place and carefully track movements over a wide area for days, or weeks proved very useful for intelligence work. Five years ago Canada began a $5 billion to upgrade and expand its fleet of LAV III wheeled armored vehicles. Over the last decade, Canada has replaced its 1980s era MOWAG and older LAV II vehicles with the locally built LAV IIIs. Canada donated many of the older wheeled armored vehicles (mostly 11 ton Grizzly personnel carriers) to nations performing peacekeeping duties.

Space-Age technology on Earth, but not so much in space

Filed under: Science, Space, Technology — Tags: , , , , — Nicholas @ 09:33

In The Register, Shaun Dormon explains why almost all the electronic components used on modern spacecraft, satellites, and the International Space Station (ISS) are actually not cutting-edge, top-of-the-line items:

I hate to say it, but most of what you think about space-age technology is a total fabrication. It’s the stuff of sci-fi.

Perhaps the biggest misconception of all is that spacecraft are equipped with cutting-edge computing platforms that any self-respecting technophile would commit unspeakable acts to get their mitts on.

If only. The fact of the matter is that even the most advanced chips up there were considered obsolete ten years ago down here. Although it’s true that in space no one can hear you scream, outer space is actually a very noisy place, electromagnetically speaking.

The computer on your desk is very unlikely to experience much in the way of EM radiation unless someone cuts a hole in the side of the kitchen microwave. Out in orbit, though, there are many sources of radiation, ranging from the relatively mundane stuff pouring out of the Sun and collecting in the Van-Allen radiation belts to more exotic things such as cosmic rays and other high-energy particles that cause so-called “single-event effects”.

[. . .]

The damage is cumulative. Individually, an impact causes the ionisation of a single oxide molecule present in the semiconductor. It’s not enough to cause instant failure, but as more and more impacts take place, the effects combine to significantly alter the electrical properties of the circuit until it can no longer function correctly.

More exciting dangers arise from exposure to gamma or cosmic rays. These ultra-high energy impacts cause localised ionisation which results in an unexpected flow of current. In the case of a lower energy event, this may result in a “single event upset” or “bit-flip”, and data corruption can ensue. These are not usually fatal to the system. No so the worst case “single event burnout”, which creates such high currents that the very circuitry itself is burned out almost instantaneously.
