Guaranteed headline in Canadian papers: mention the Avro Arrow

Filed under: Cancon, History, Military, Technology — Tags: , , , , — Nicholas @ 10:29

Today it’s the National Post (actually, it’s just a Canadian Press wire piece) chumming the waters with a report on an “Avro Arrow redesign pitched as alternative to controversial F-35”:

A Canadian company is seeking to go back in time to help fly Canada’s air force into the future.

Documents obtained by the Global News program “The West Block” indicate an update to the storied CF-105 Avro Arrow was put forward as an alternative to the purchase of F-35 stealth fighter jets.

And among the project’s champions is one of Canada’s top soldiers, retired Maj.Gen. Lewis MacKenzie.

The Arrow was an advanced, all-weather supersonic interceptor jet that was developed in the 1950s. Several prototypes were built and flight tests were conducted, but the project was abruptly shut down in 1959 and the aircraft never went into production.

Even people who care less than nothing about aircraft or military technology seem to have opinions about the Avro Arrow (usually allowing them to take free shots at former Prime Minister John Diefenbaker for the decision to scrap the plane). It’s far enough in the past that the facts are more than obscured by the myths of the cottage conspiracy theory industry (artisanal Canadian myth-making, hand-woven, fair-trade, and 100% organic).

The Avro Arrow is the story that never dies in Canadian papers.

Jesse Kline: Consumers the biggest losers in Apple-Samsung battle

Filed under: Business, Law, Technology — Tags: , , , , — Nicholas @ 00:07

In the National Post, Jesse Kline points out that the grubby legal dispute between Apple and Samsung may end up hurting the consumer much more than either of the combatants:

Software is unique because it is covered under both copyright and patent law. Computer software is written in a human-readable language, called source code, that is then translated by the computer into something the machine can understand. Much like writing a book, or newspaper article, source code is automatically covered under copyright law.

But no one is alleging that Samsung copied Apple’s code. What Samsung was sued for was achieving the same outcome as Apple, even though it was done in a different way. In this literary world, this would be akin to someone being sued for violating the copyright on Harry Potter, just because they wrote their own story about a boy wizard.

Intellectual property laws are supposed to encourage innovation by allowing companies and individuals to profit off works that may have cost a significant amount of money to develop. Apple says it was undercut in price because its competitor simply copied its design. In actual fact, Android was cheaper to produce because it is based on the open source Linux operating system, which saved money compared to Apple proprietary system.

For its part, Samsung accuses Apple of resorting “to litigation over market competition in an effort to limit consumer choice.” It’s one thing for the legal system to protect new inventions and original works, but this is quite clearly a case of a company engaging in anti-competitive behaviour.

The debut of energy weapons in the real military world

Filed under: Military, Technology, USA, Weapons — Tags: , , — Nicholas @ 00:03

The Economist looks at the long-anticipated introduction of energy weapons. They’re still a long way from matching the fictional capabilities of phasers, blasters, disruptors, or photon torpedoes:

In the late 1970s and early 1980s the idea was revived when American strategists began thinking in earnest about the technologies they would need to shoot down nuclear-armed ballistic missiles. Among the more fanciful ideas taken up by Ronald Reagan’s Strategic Defence Initiative (more commonly known as Star Wars) was the X-ray laser, which aimed to harness the energy of an atomic explosion to generate powerful laser beams. The hassle of having to explode a nuclear bomb every time a beam was needed meant the idea never went anywhere, though it did spur research into high-powered chemical lasers and the sophisticated optics needed to aim and control them.

The main appeal of using an energy beam to shoot things is that it travels at the speed of light, which means, in practice, that it will hit whatever it is aimed at. Trying to shoot down an incoming missile or warhead with a physical projectile, by contrast, is much more difficult. The guidance challenges of trying to “hit a bullet with a bullet” are enormous and are only gradually being solved using complex radars and missiles equipped with expensive sensors. A second attraction of lasers and other energy weapons is that in most cases they cannot run out of ammunition, and can keep firing for as long as they are plugged into a power source. The initial costs may be quite high, but each shot may then cost only a few dollars, compared with a price-tag of $3m or more for the latest missiles used to shoot down aircraft or other missiles.

[. . .]

The big trend now is to try to scale up three other sorts of laser that are far more compact than chemical lasers and can fire away merrily as long as they have power and don’t get too hot. The first sort is the fibre laser, in which the beam is generated within an optical fibre. Because this is already used in industry for welding and cutting, prices are falling, power output is increasing and reliability has been steadily improving. Industrial lasers can be turned into weapons pretty easily, simply by strapping them to a weapons mount.

But they are not very powerful. The Tactical Laser System being developed for the American navy by BAE Systems, a British firm, has an output of just 10kW, enough to run a few household kettles. Even so, it might be useful for frightening off (or burning holes in) small boats that look threatening but wouldn’t warrant a hail of machinegun fire. A slightly bigger version puts out about 33kW of power and fits neatly on existing turrets that house the rotary cannons used to shoot down incoming anti-ship missiles. It could blind optical or heat-seeking sensors on enemy missiles, or puncture small boats.

Switzerland to buy Swedish warplanes

Filed under: Europe, Military, Technology — Tags: , , — Nicholas @ 09:12

Switzerland is planning to replace their aging fleet of F-5 fighter jets with a smaller number of modern Swedish aircraft:

Switzerland has decided to buy 22 Swedish JAS-39E Gripen fighters to replace their elderly F-5s. The 16 ton JAS-39E is roughly comparable with the latest versions of the F-16 and is a substantial upgrade of the current JAS-39C model. The Gripen is also used by Sweden, Thailand, South Africa, Hungary, and the Czech Republic. The 39E is still in development and will eventually replace the 14 ton JAS-39C.

[. . .]

Often regarded as an also-ran in the current crop of “modern jet fighters,” the Swedish Gripen is proving to be more competition than the major players (the F-16, F-18, F-35, Eurofighter, Rafale, MiG-29, and Su-27) expected. Put simply, Gripen does a lot of little but important things right and costs about half as much (at about $35 million each) as its major competitors. In effect, Gripen provides the ruggedness and low cost of Russian aircraft with the high quality and reliability of Western aircraft. For many nations this is an appealing combination. The Gripen is easy to use (both for pilots and ground crews) and capable of doing all jet fighter jobs (air defense, ground support, and reconnaissance) well enough.

The Gripen is small but can carry up to 3.6 tons of weapons. With the increasing use of smart bombs, this is adequate. The aircraft entered active service in 1997 and has had an uphill battle getting export sales. Sweden does not have the diplomatic clout of its major competitors, so they have to push quality and service. Swedish warplanes and products in general have an excellent reputation in both categories. Nevertheless, the Gripen is still expected to lose out on a lot of sales simply because politics took precedence over performance.

Update: Yes, I caught the mis-attribution in the headline about a minute after I posted this. Sorry for the error, etc., etc., etc.

US Army’s JTRS program a poster child for development failure

Filed under: Bureaucracy, Military, Technology, USA — Tags: , , , , — Nicholas @ 09:35

Strategy Page has the details:

It’s been eleven months now since the U.S. Army cancelled its 15 year effort to develop the JTRS (Joint Tactical Radio System). This program cost over $6 billion and has been a major embarrassment for the U.S. Department of Defense. Actually, JTRS still exists, on paper, but its goal, to provide better combat radios, has been accomplished by adopting civilian radios that do what the troops needed done and calling it JTRS. In the time the army spent working on JTRS some $11 billion was spent on buying more radios using existing designs, and a lot of off-the-shelf equipment incorporating stuff JTRS was supposed to do.

JTRS was yet another example of a military development project that got distracted, and bloated, trying to please everyone. There was, in a word, no focus. There’s been a lot of this in the last decade. That’s what killed the Comanche light attack helicopter, the Crusader self-propelled howitzer, FCS (Future Combat System), the Seawolf SSN, the DDG-1000 destroyer, B-2 bomber, F-22 fighters and several military space satellite projects. In all cases some of the technology developed was put to use in cheaper systems and sometimes a few of the cancelled systems were built (three Seawolfs, three DDG-1000s, 21 B-2s and 187 F-22s). These cancellations and cutbacks saved over half a trillion dollars. That goes a long way towards paying for projects that were not cancelled and are nearly half a trillion dollars over budget. But overall these failures were expensive and embarrassing.

JTRS, however, was the poster child of what usually goes wrong and how it impacts the combat troops. After all, radios are something personnel in all services use a lot. The main problem with JTRS was that the troops needed digital (for computer stuff) and analog (traditional radio) communications in one box and it had to be programmable, in order to handle new applications and the need to communicate with other radio types. That’s what JTRS was supposed to do but it never happened. The procurement bureaucracy and government contractors consumed over six billion dollars but never quite got anything useful out the door.

The importance of encryption for private citizens

Filed under: History, Liberty, Technology — Tags: , , , , — Nicholas @ 11:26

Wendy McElroy relates one of the earliest examples of private encryption in the young American republic:

In America, the tug of war between privacy and forced access to encrypted data is as old as the nation’s formation. As always, forced access was executed by authorities against individuals.

In 1785, a resolution authorized the secretary of the Department of Foreign Affairs to open and inspect any mail that related to the safety and interests of the United States. The ensuing inspections caused prominent men, like George Washington, to complain of mail tampering. According to various historians, it also led James Madison, Thomas Jefferson and James Monroe to correspond in code. That is, they encrypted their letters to preserve the privacy of their political discussions.

The need for Founding Fathers to encrypt their correspondence is high irony. The intrusive post office against which they rebelled had been established specifically to provide a free flow of political opinion. In the 1770′s, Sam Adams urged the 13 colonies to create an independent postal system because the existing post office, established by the British, acted as a barrier to the spread of rebellious sentiment. Dorothy Ganfield Fowler in her book Unmailable: Congress and the Post Office observed, “He [Adams] claimed the colonial post office was made use of for the purpose of stopping the ‘Channels of publick Intelligence and so in Effect of aiding the measures of Tyranny.’”

Alas, the more government changes, the more oppression remains the same. Soon the Continental Congress itself wanted to declare some types of matter ‘unmailable’ because their content were deemed dangerous. Anti-Federalist letters and periodicals became one of the first types of information to become de facto unmailable. (Anti-federalists resisted centralized government and rejected a Constitution without a Bill of Rights.) During the ratification debates on the Constitution, the Anti-Federalists were unable to circulate their material through the Federalist-controlled post office.

Digital “inheritance”: law has not caught up to our online lives

Filed under: Law, Media, Technology — Tags: , , , — Nicholas @ 00:01

As I mentioned in a post the other day, our laws are still designed for a world where most things have a physical presence, and the problems we see in intellectual property and patent law are just the start of the turmoil our legal system will have to face:

What will happen to your Facebook account after you are gone?

Dealing with digital assets after someone dies is becoming a challenge for families and the legal system alike.

Lawmakers are trying to clarify rules governing the passage of social-media and email accounts, along with other online assets that might have financial value. Several states have enacted laws to deal with post-death access to digital assets, and several more are working on similar legislation, says Gene Hennig, a lawyer at Gray Plant Mooty in Minneapolis and a commissioner of the Uniform Law Commission.

That group, which recommends uniform state laws, plans to come up with a recommended statute that more states could adopt.

“Eventually people are going to start putting in their wills what they want, and we need to know what’s allowed,” Mr. Hennig says. “In the olden days, grandma had a chest in the attic full of photo albums. Now, your chest of photos is in your computer.”

Update, 3 September: Bruce Willis wants his kids to inherit the music library he’s built up, but the iTunes licensing won’t let him do that.

Colby Cosh on Neil Armstrong’s finest moment

Filed under: History, Space, Technology — Tags: , , , — Nicholas @ 10:30

No, it’s not what you think at all:

On March 16, 1966, Armstrong and future Apollo 15 moonwalker David R. Scott became the first human beings to dock an orbiting spacecraft with an independently launched satellite, the Agena. (As proofs-of-concept go, this one has been more important to spaceflight than the moon landings.) The procedure proved surprisingly unchallenging; when the Gemini capsule nosed into place, Armstrong blurted out, “It’s really a smoothie!” The Gemini-Agena combo — mankind’s first “space station” — moved out of radio contact with mission control 28 minutes later. When it came back in range after another 15, Armstrong’s first words were, “We have serious problems here.” A wiring problem had left one of the attitude thrusters on Gemini stuck in the “on” position — firing continuously and causing an increasing left roll. Unsure what was causing the problem, Armstrong made the snap decision to separate from the Agena. But the problem was on their side, and without the Agena’s inertia, the Gemini craft began to spin even faster.

Press accounts said the pair were spinning at about one revolution per second. Senior mission controller Chris Kraft has since noted that their peak rotation was actually 550 degrees a second. Only a trained test pilot could make good decisions while whirling around in freefall 90 times a minute — and Armstrong justified the use of test pilots in space for all time by using Gemini’s re-entry thrusters to dampen the roll and save himself and Scott. By rule, the use of those thrusters meant the mission had to be aborted early. Armstrong and Scott suffered tense hours as they waited to see if they would splash down short of their Pacific landing zone, on the soil of Communist China.

Armstrong was rueful about the abort, which cost Scott the chance to make a spacewalk and cut short the experiment with Agena. But NASA was impressed. One of the agency’s main concerns before the moon missions was that astronauts trying to set down the lunar module would refuse to abort the landing, even if they ran too short on fuel to leave the moon. Armstrong, alone among astronauts of the time, had established a record of outstanding sanity in the face of an emergency. He would probably like to be remembered for that — for making the right choice, a pilot’s choice — at least as much as for the trail he left in the dust of the moon.

Innovative ways to use huge surplus of beetle-blighted lumber

Filed under: Cancon, Environment, Technology — Tags: , , , — Nicholas @ 09:07

British Columbia has a problem with their trees: too many of them are dead due to a massive increase in the population of the mountain pine beetle. The province is searching for ways to cope with the lumber from all the beetle-killed trees:

When life hands you lemons, goes the old saw, make lemonade. But what if life should hand you 18m hectares (44m acres) of dead trees? That is the problem faced by the province of British Columbia in Canada, which could lose over half its pine trees to the depredations of the fearsome mountain pine beetle. The beetle, no bigger than a grain of rice, is native to the forests of Western North America, where it kills trees by releasing a blue stain fungus that prevents the flow of water and nutrients. While the insect was historically kept in check by spells of cold weather, years of mild winters have unleashed an outbreak whose spread and severity is unlike anything seen previously.

As a result, the province is peppered with billions of dead, grey trees. If they are simply left standing, they will eventually either decay or burn in forest fires. In either case, they will release the carbon dioxide they stored while growing, swelling Canada’s total carbon footprint from 2000 to 2020 by 2%.

[. . .]

Canadian researchers have discovered other uses for BKP. Sorin Pasca, a graduate student at the University of Northern British Columbia, found that rain and snow conveniently wash out sugars and other organic compounds from dead pine trees. By grinding up the dry BKP and adding it to normal cement, he created a hybrid material that is waterproof, fire-resistant and pourable like concrete but that can be worked, cut and nailed or drilled like wood. The material, dubbed Beetlecrete, has already been used to make countertops, benches and planters.

Even more esoteric uses for BKP are on the table. Nanocrystalline cellulose, made up of microscopic needle-like fibres, is a lightweight, ultra-rigid material that can be extracted from wood pulp. Currently used to improve the durability of paints and varnishes, nanocrystalline cellulose promises strong, iridescent films that may find uses in industries ranging from optical computing to cosmetics. And, as a last resort, dead and fallen pine trees can feed British Columbia’s 800MW of bio-mass power plants, which burn pellets of BKP and other waste wood to generate electricity.

21st century problems: who inherits your digital property?

Filed under: Books, Law, Media, Technology — Tags: , , , , — Nicholas @ 08:37

Unless medical science has a solution up their collective sleeves, we’re all going to die (eventually). It may be an individual shock, but humans have been dying forever — it’s the unwelcome end of the trip. As a result, we’ve evolved ways to redistribute the property of deceased members of our families and communities. When the issues were as simple as who got Uncle Grog’s club and who got his loincloth, we came up with solutions.

Fast forward to our becoming-ever-more-digital age, and not all of our property is tangible: we’re becoming “owners” of digital property that may be as valuable as our physical possessions. What happens to our music libraries, e-book collections, social media accounts, and all the other non-physical things we’ve bought and used during our lives?

Someone who owned 10,000 hardcover books and the same number of vinyl records could bequeath them to descendants, but legal experts say passing on iTunes and Kindle libraries would be much more complicated.

And one’s heirs stand to lose huge sums of money. “I find it hard to imagine a situation where a family would be OK with losing a collection of 10,000 books and songs,” says Evan Carroll, co-author of “Your Digital Afterlife.” “Legally dividing one account among several heirs would also be extremely difficult.”

Part of the problem is that with digital content, one doesn’t have the same rights as with print books and CDs. Customers own a license to use the digital files — but they don’t actually own them.

[. . .]

Most digital content exists in a legal black hole. “The law is light years away from catching up with the types of assets we have in the 21st Century,” says Wheatley-Liss. In recent years, Connecticut, Rhode Island, Indiana, Oklahoma and Idaho passed laws to allow executors and relatives access to email and social networking accounts of those who’ve died, but the regulations don’t cover digital files purchased.

Apple and Amazon did not respond to requests for comment.

Restarting the age of space

Filed under: Media, Space, Technology — Tags: , , , , , — Nicholas @ 09:24

sp!ked reposted an older article by James Woudhuysen on the long-term importance of space exploration and the stay-at-home attitudes that oppose further development of the “final frontier”:

One thing unites the critics of lunar exploration. Forty years after man first landed on the moon — on 20 July 1969 — they share a disdain for the grandeur of extra-terrestrial endeavour; for the scale of human ambition involved; for the very idea that human beings should climb into space, as up a mountain, ‘because it is there’.

I have no special preference for size, thrust during lift-off, or the traverse across vast distances. The development of the integrated circuit in the late 1950s, so important to the Apollo programme, was a tribute to miniaturisation rather than to high energy or physical scale. No, my admiration for both Saturn boosters and tiny electronics grows from a respect for open-ended curiosity, for human achievement, and for taking risks. With space travel, a lot of bravery was also at stake. And with both space and the development of semiconductors, there is much teamwork to celebrate — teamwork that, in the case of Apollo, involved not just three astronauts, but the efforts of hundreds of thousands of people.

Google investigates their own in-house Gender Gap

Filed under: Business, Economics, Technology, USA — Tags: , , , — Nicholas @ 00:02

Tim Worstall in Forbes on Google’s unique approach to narrowing the Gender Gap:

As we all know, because we’re reminded about it often enough in rather shrill voices, the gender gap is one of the more pernicious unfairnesses in our society. This idea that women only earn 77 cents to a $1 for men, don’t get the same promotions, are in fact discriminated against by society.

The thing is, the more people study this question the less and less it’s possible to see that there is in fact a gender gap. Or rather, a gender gap driven by discrimination. Do note that economists discriminate (sorry) between taste discrimination and rational discrimination. Taste discrimination would be where women were treated worse than men just because they are women. Akin to say the dreadful racism of the past: and we would all admit that there was indeed discrimination against women in the workplace in the past.

What is a great deal less certain is whether this taste discrimination still exists: of course, we’ll always be able to find examples of it, but does it exist in a general sense, across the economy? Many researchers think not: for when you add up the effects of rational discrimination then look at the gender gap there doesn’t seem to be much if any room left for that taste discrimination. Rational discrimination is things like, well, women and men do tend to self-segregate into different occupations. Some of which are higher paid than others. Men tend to be willing to take riskier jobs and thus earn a danger premium to their wages. Women tend to negotiate less hard for their wages or a promotion. And of course women do tend to be those who take career breaks to have and to raise children. Perhaps this shouldn’t be so but it is and it’s most certainly true that the largest contributor to the gender pay gap is not gender itself but the effects of motherhood.

This is all pretty well known in the academic literature. What Google has done is most unfair. It has entirely ignored the academic work, ignored the partisans of both sides, and actually gone and asked its own staff what’s going on.

Crisis malware is particularly capable of damage

Filed under: Technology — Tags: , , — Nicholas @ 00:03

John Leyden in The Register:

Security watchers have discovered a virus strain that compromises VMware virtual machines as well as infecting Mac OS X and Windows computers and Windows Mobile devices. It demonstrates previously unseen capabilities in the process.

The Crisis malware typically arrives in a Java archive file (.jar) and is typically installed by posing as a Flash Player Java applet to trick a victim into opening it.

The archive contains executable files targeting Apple and Microsoft operating systems; the malware is able to detect which platform it is running on and serve up the correct variant.

Once launched, the worm puts in place a rootkit to hide itself from view; installs spyware to record the user’s every move on the computer; and opens a backdoor to the IP address 176.58.100.37, allowing miscreants to gain further access to the machine, according to a write-up of the threat by Kaspersky Lab. The malicious code also, unsurprisingly, survives across reboots.

The Windows variant can kill off antivirus programs, log keypresses, download and upload files, take screengrabs, lift the contents of the user’s clipboard, record from the computer’s webcam and mic, and snoop on these applications: Firefox, Internet Explorer, Chrome, Microsoft Messenger, Skype, Google Talk and Yahoo! Messenger.

Kicking the Baby Boomers while they’re down

Filed under: Media, Technology, USA — Tags: , , — Nicholas @ 09:49

P.J. O’Rourke laments the America that was, before the Baby Boomers came along and ruined everything:

The United States has set itself on a course of willful self-diminishment. Seventy-four years ago the perfect American was Superman, who happened to have been, like many of our forefathers, an undocumented alien. If Superman arrived today — assuming he could get past the INS and Homeland Security — he would be faster than the postal service, more powerful than a New York Times blogger, and able to ascend tall buildings in a single elevator.

[. . .]

America has had plenty of reasons to abdicate the crown of accomplishment and marry the Wallis Simpson of homely domestic concerns. Received wisdom tells us that, in the matter of great works and vast mechanisms, all is vanity. The Nurek Dam probably endangers some species of Nurek newt and will one day come crashing down in a manner that will make the aftermath of Japan’s Fukushima tsunami look like an overwatered lawn. And we have better things to spend our country’s money on, like putting a Starbucks on every city block. But I suspect there’s a sadder reason for America’s post-eminence in things tremendous, overwhelming, and awesome.

My sad generation of baby boomers can be blamed. We were born into an America where material needs were fulfilled to a degree unprecedented in history. We were a demographic benison, cherished and taught to be self-cherishing. We were cosseted by a lush economy and spoiled by a society grown permissive in its fatigue with the strictures of depression and war. The child being father to the man, and necessity being the mother of invention, we wound up as the orphans of effort and ingenuity. And pleased to be so. Sixty-six years of us would be enough to take the starch out of any nation.

The baby boom was skeptical about America’s inventive triumphalism. We took a lot of it for granted: light bulb, telephone, television, telegraph, phonograph, photographic film, skyscraper, airplane, air conditioning, movies. Many of our country’s creations seemed boring and square: cotton gin, combine harvester, cash register, electric stove, dishwasher, can opener, clothes hanger, paper bag, toilet paper roll, ear muffs, mass-produced automobiles. Some we regarded as sinister: revolver, repeating rifle, machine gun, atomic bomb, electric chair, assembly line. And, ouch, those Salk vaccine polio shots hurt.

The Soviet Union’s 1957 launch of Sputnik caused a blip in chauvinistic tech enthusiasm among those of us who were in grade school at the time. But then we learned that the math and science excellence being urged upon us meant more long division and multiplying fractions.

Royal Navy faces shortage of trained submariners

Filed under: Britain, Military, Technology, Weapons — Tags: , , , — Nicholas @ 08:56

Thomas Harding in the Telegraph:

Internal documents warn that a lack of recruits for the Submarine Service may leave attack submarines and boats carrying the Trident nuclear missile stranded in port.

A separate threat comes from a predicted 15 per cent shortfall in engineers by 2015.

One in seven posts for weapons officers at the rank of lieutenant will also be vacant, raising operational questions over the boats equipped with nuclear and cruise missiles.

Many submariners are being poached by the civilian nuclear sector and those who remain are being forced to go to sea for longer and more frequently.

Adml Lord West, the former First Sea Lord, said the situation was “very worrying” and he hoped the Navy had mechanisms in place to make up for the shortfall.

[. . .]

The Navy has a fleet of six attack submarines and four Vanguard boats that carry the Trident nuclear missile, but the personnel issues could mean they cannot be deployed.

The report found that the recruiting and retention of submariners was also threatening operations. “Inability to recruit, retain and develop sufficient nuclear and submarine design qualified personnel will result in an inability to support the Defence Nuclear Programme,” the document said.
