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.

“3D printing will be bigger than the web”

Filed under: Business, Technology — Tags: , , , , — Nicholas @ 12:46

While I’m not quite willing to go as far as Chris Anderson (quoted above), I do think 3D printing is going to be a fantastic development in our very-near future:

Chris Anderson has exited one of the top jobs in publishing — Editor-in-Chief of Wired magazine — to pursue the life of an entrepreneur, making a big bet that 3D printers represent a massive new phase of the industrial revolution.

He spoke at a Wired “Culturazzi” event, at the Marriott Union Square and to sign copies of his latest book: Makers: The New Industrial Revolution.

Mr Anderson is always an excellent speaker and his talk covered the beginnings of the Industrial Revolution, which he picked out as the invention of the Spinning Jenny in 1764 — a hand powered machine for spinning yarn.

I’d have pinned the start of the Industrial Revolution to the invention of the steam engine and its ability to power large numbers of machines thus enabling the first factories — which represented aggregated labor energy. Scale makes factories viable.

But I can see why Mr Anderson would favor the Spinning Jenny as it was a high-tech machine that was kept in a home — just as 3D printers are home based, completing a neat cycle of history.

A new low in patents?

Filed under: Bureaucracy, Law, Technology, USA — Tags: , , , — Nicholas @ 10:35

Apple has patented the “page turn”:

If you want to know just how broken the patent system is, just look at patent D670,713, filed by Apple and approved this week by the United States Patent Office.

This design patent, titled, “Display screen or portion thereof with animated graphical user interface,” gives Apple the exclusive rights to the page turn in an e-reader application.

Yes, that’s right. Apple now owns the page turn. You know, as when you turn a page with your hand. An “interface” that has been around for hundreds of years in physical form. I swear I’ve seen similar animation in Disney or Warner Brothers cartoons.

Latest advances in “trouser-cough suppression”

Filed under: Health, Japan, Technology — Tags: — Nicholas @ 10:34

Lester Haines has a bit of fun with this “news” article:

Pairs of fart-absorbing underpants designed to contain the copious trouser cough output from Irritable Bowel Syndrome sufferers have proved a hit with Japanese businessmen.

Manufacturer Seiren expressed pleasant surprise that their guff-busting smalls had attracted the attention of suits more accustomed to allocating most of their underwear budget to schoolgirls’ used knickers.

Spokeswoman Nami Yoshida said: “It took us a few years to develop the first deodorant pants that are comfortable enough to wear in daily life but efficient in quickly eliminating strong smells.

Enter the real Facebook business model

Filed under: Business, Technology — Tags: , , — Nicholas @ 10:13

Facebook is changing, and lots of folks have ideas about what it is changing into. Here’s Dalton Caldwell‘s interpretation of the new business model:

Several prominent people are up in arms about Facebook charging for access to users who have already Liked their page.

I believe this debate is missing the big picture, and what we are in fact witnessing is the unfurling of the full-fledged Facebook business model. Facebook is showing us how they will cross the chasm from low-CTR low-CPM ad-units into what investors have been waiting for since the beginning: a Facebook analogue to Google Adwords.

[. . .]

From a Facebook user perspective, we don’t really know how the algorithm works, and are already trained to understand that some things magically show up our newsfeed and some things don’t. If a normal user sees that one of their friends bought a LivingSocial deal at the top of their feed, they may/may not click on it, but they certainly won’t question how it got there.

Facebook newsfeed is an embodiment of our war on noise. We depend on the newsfeed optimizer to protect our limited attention span, and as a consequence, Facebook gets to choose what stories we do and don’t see, just as Google chooses which search results we do and don’t see. Conceptually, this seems very lucrative: Facebook is auctioning off our limited attention span to the highest bidder, as long as the bidder has a candidate newsstory to promote.

This is what Like-gate is about.

Welcome to the attention economy.

From strategic nuclear bomber to “bomb truck”

Filed under: Military, Technology, USA — Tags: , , — Nicholas @ 09:08

The B-52 is still in service with the US Air Force and still finding roles to play:

The U.S. Air Force is continuing to upgrade its fifty year old B-52s. The latest upgrade will enable each B-52 to carry over 110 of the 130 kg (285 pound) Small Diameter Bombs (SDB, also known as the GBU-39/B). Six years ago the rotary bomb rack inside the B-52 was modified to carry 32 SDBs instead of 15 larger bombs.

The SDB was designed from the bottom up as a smart bomb. The SDB has a more effective warhead design and guidance system. Its shape is more like that of a missile than a bomb (nearly two meters, as in 70 inches, long, and 190mm in diameter), with the guidance system built in. The smaller blast from the SDB resulted in fewer civilian casualties. Friendly troops can be closer to the target when an SDB explodes. While the 500, 1,000 and 2,000 pound bombs have a spectacular effect when they go off, they are often overkill. The troops on the ground would rather have more, and smaller, GPS bombs available. This caused the 500 pound JDAM to get developed quickly and put into service. But it wasn’t small enough for many urban combat situations. The SDB carries only 17 kg (38 pounds) of explosives, compared to 127 kg (280 pounds) in the 500 pound bomb. The SDB is basically an unpowered missile, which can glide long distances. This makes the SDB even more compact. The small wings allow the SDB to glide up to 70-80 kilometers (from high altitude.) SDB also has a hard front end that can punch through nearly three meters (eight feet) of rock or concrete, and a warhead that does less damage than the usual dumb bomb (explosives in a metal casing.) The SDB is thus the next generation of smart bombs. The more compact design of the SDB allows more to be carried. Thus F-15/16/18 type aircraft can carry 24 or more SDBs. The SDBs are carried on a special carriage, which holds four of them. The carriage is mounted on a bomber just like a single larger (500, 1,000 or 2,000) pound bomb would be. However, this feature was rarely needed in combat situations.

This makes the B-52 even more effective as the cheapest to operate and most reliable “bomb truck” the air force has. With a max takeoff weight of 240-250 tons the BUFF (Big Ugly Fat Fellow) is basically a large aircraft designed to carry bombs cheaply and efficiently. Last year the readiness rate of these bombers was 78 percent. Although a half century old, most of the internal fear has been replaced with modern electronics and furnishings. It’s all flat screens and modern gear. Look closer and you see fifty year old metal.

Protecting children from online pornography – the impossible dream

Filed under: Britain, Media, Technology — Tags: , , , — Nicholas @ 10:46

In the Guardian, Cory Doctorow talks about the actual scale of effort the British government is attempting to mandate to “protect the children from pr0n”:

In order to filter out adult content on the internet, a company has to either look at all the pages on the internet and find the bad ones, or write a piece of software that can examine a page on the wire and decide, algorithmically, whether it is inappropriate for children.

Neither of these strategies are even remotely feasible. To filter content automatically and accurately would require software capable of making human judgments — working artificial intelligence, the province of science fiction.

As for human filtering: there simply aren’t enough people of sound judgment in all the world to examine all the web pages that have been created and continue to be created around the clock, and determine whether they are good pages or bad pages. Even if you could marshal such a vast army of censors, they would have to attain an inhuman degree of precision and accuracy, or would be responsible for a system of censorship on a scale never before seen in the world, because they would be sitting in judgment on a medium whose scale was beyond any in human history.

Think, for a moment, of what it means to have a 99% accuracy rate when it comes to judging a medium that carries billions of publications.

Consider a hypothetical internet of a mere 20bn documents that is comprised one half “adult” content, and one half “child-safe” content. A 1% misclassification rate applied to 20bn documents means 200m documents will be misclassified. That’s 100m legitimate documents that would be blocked by the government because of human error, and 100m adult documents that the filter does not touch and that any schoolkid can find.

In practice, the misclassification rate is much, much worse. It’s hard to get a sense of the total scale of misclassification by censorware because these companies treat their blacklists as trade secrets, so it’s impossible to scrutinise their work and discover whether they’re exercising due care.

Firefox users more likely to stay on old version longer than other browser users

Filed under: Technology — Tags: , , — Nicholas @ 08:47

John Leyden summarizes the recent findings about how quickly users update their web browsers after a new release:

Nearly one in four netizens are using outdated web browsers and are therefore easy pickings for viruses and exploit-wielding crooks.

The average home user upgrades his or her browser to the latest version one month after it is released, according to a survey of 10 million punters. Two thirds of those using old browser software are simply stuck on the version prior to the latest release — the remaining third are using even older code.

Internet Explorer is the most popular browser (used by 37.8 per cent of consumers), closely followed by Google Chrome (36.5 per cent). Firefox is in third place with 19.5 per cent.

Firefox users tend to be the worst for keeping up to date with new software releases, according to the survey by security biz Kaspersky Lab. The proportion of users with the most recent version installed was 80.2 per cent for Internet Explorer and 79.2 per cent for Chrome, but just 66.1 per cent for Firefox.

Old-codgers Internet Explorer 6 and 7, with a combined share of 3.9 per cent, are still used by hundreds of thousands of punters worldwide.
