Britain’s entry in the new race to space

Filed under: Britain, Space, Technology — Tags: , , — Nicholas @ 09:12

Jonathan Amos reports on the UK Space Agency (UKSA) long-simmered design/proposal called Skylon:

Skylon has been in development in the UK in various guises for nearly 30 years.

It is an evolution of an idea first pursued by British Aerospace and Rolls Royce in the 1980s.

That concept, known as Hotol, did have technical weaknesses that eventually led the aerospace companies to end their involvement.

But the engineers behind the project continued to refine their thinking and they are now working independently on a much-updated vehicle in a company called Reaction Engines Limited (REL).

Realising the Sabre propulsion system is essential to the success of the project.

The engine would burn hydrogen and oxygen to provide thrust — but in the lower atmosphere this oxygen would be taken directly from the air.

This means the 84m-long spaceplane can fly lighter from the outset with a higher thrust-to-weight ratio, enabling it to make a single leap to orbit, rather than using and dumping propellant stages on the ascent — as is the case with current expendable rockets.

Update: Lewis Page has more on the Skylon project.

Why is the move to IPv6 so important?

Filed under: Media, Technology — Tags: , — Nicholas @ 08:42

As you may remember, June 8th is World IPv6 Day, where hundreds of major players including Google, Facebook, and Yahoo will all turn on IPv6 access (but then turn it off again at the end of the day). It seems odd to make a big to-do about IPv6 Day then go back to business as usual after 24 hours. Most end users will not notice the change, as most of us connect through our various ISP networks using IPv4 addresses anyway.

So, what happens if IPv6 isn’t taken up by the movers and shakers of the networking world?

Proponents of IPv6 make dire predictions about the fate of the Internet if usage of IPv6 doesn’t rise dramatically in the next few years. They say the complexity of the Internet infrastructure will increase, network operations costs will rise, and innovation will be hampered. This is due to the multiple layers of network address translation (NAT) devices that will be required to share limited IPv4 addresses among a rapidly growing base of users and devices.

“If IPv6 fails to catch on, then the Internet will include nesting of NAT upon NAT,” says Russ Housley, chairman of the Internet Engineering Task Force (IETF), the Internet standards body that created IPv6. “I hope this is not our future because it would be a very fragile Internet, making innovation more difficult. On the other hand, IPv6 will greatly reduce the need for NAT, restoring the opportunities for innovation that were envisioned by the original Internet architecture.”

Dorian Kim, vice president of IP engineering, Global IP Network at NTT America, a leading provider of IPv6 services in the United States, says that without IPv6 the Internet “will be even more heavily NATed than it currently is, but life will mostly go on. Unfortunately, such an Internet likely will have a negative effect on potential development of application or service innovation due to inherent issues with NATs. Additionally, should service providers become more and more reliant on NATs, this will probably change the cost and scaling trajectories of Internet services over time due to high cost and limited scalability of large-scale NAT solutions.”

President of TEPCO falls on his sword a few months late

Filed under: Environment, Health, Japan, Media, Technology — Tags: , , , , — Nicholas @ 11:04

The president of the Tokyo Electric Power Co. (TEPCO) has resigned:

In a business practice that recalled the ritual seppuku suicides of samurai warriors, the president of Japan’s largest power company resigned Friday to assume responsibility for the world’s worst nuclear disaster since Chernobyl.

At a nationally televised news conference, Masataka Shimizu bowed deeply in an exhibition of remorse and declared, “I am resigning for having shattered public trust about nuclear power and for having caused so many problems and fears for the people.

“I want to take managerial responsibility and bring a symbolic close.”

Whether it’s a hearkening-back to Samurai ethos or not, he should have resigned long ago, as soon as it became clear that the company he headed was doing everything it could to conceal the extent of the actual damage both from the media and from the government.

There is a widespread feeling the government and TEPCO officials did not disclose all they knew during the early days of the crisis and have been less than forthcoming since.

In the first weeks after the earthquake, TEPCO officials received 40,000 complaints a day about the lack of information. Police had to be assigned to guard the company’s offices from anti-nuclear protesters.

This week, TEPCO released documents showing it was dealing with three simultaneous nuclear meltdowns, while reassuring people the fuel rods were safely intact in all the reactors.

“Why did it take two months to get to this point?” demanded a Wednesday editorial in the Nikkei business newspaper.

“Even a rough calculation of conditions inside the reactors would have helped in choosing the best response.”

Public confidence was shaken further when it emerged engineers at Fukushima were so unprepared for the disaster, they had to scavenge flashlights from nearby homes and used car batteries to try to reactivate damaged reactor gauges.

Nobody with an ounce of sense is criticizing the workers at the plant for their reaction to an earthquake that was far in excess of the design for the reactors, or a tsunami that was much higher than anything the designers had foreseen. Shit happens, and it was the daily double of fantastically unlikely natural disasters that struck the plant.

The company, however, deserves more than just a light dusting of shame for the way they appear to have been actively preventing the real state of the plant becoming known to the international nuclear community and the national government. A nuclear disaster is everyone’s business, and there were resources available to TEPCO that they signally failed to draw upon. Saving face is not an acceptable reaction to this kind of catastrophe.

Only one high speed rail line in the world is profitable

Filed under: Economics, Government, Japan, Technology, USA — Tags: , , , — Nicholas @ 09:39

Babbage looks at the economics of the various high speed railway lines both in service and planned:

Of all the high-speed train services around the world, only one really makes economic sense — the 550km (350-mile) Shinkansen route that connects the 30m people in greater Tokyo to the 20m residents of the Kansai cluster of cities comprising Osaka, Kobe, Kyoto and Nara. At peak times, up to 16 bullet trains an hour travel each way along the densely populated coastal plain that is home to over half of Japan’s 128m people.

Having worked for many years in Tokyo, with family in Osaka, your correspondent has made the two-and-a-half hour journey on the Tokaido bullet-train many times. It is clean, fast and highly civilised, though far from cheap. It beats flying, which is unbearably cramped by comparison, just as pricey, and dumps you an hour from downtown at either end.

The sole reason why Shinkansen plying the Tokaido route make money is the sheer density — and affluence — of the customers they serve. All the other Shinkansen routes in Japan lose cart-loads of cash, as high-speed trains do elsewhere in the world. Only indirect subsidies, creative accounting, political patronage and national chest-thumping keep them rolling.

California’s planned 800-mile high speed rail route cannot possibly earn a profit, for many reasons (not least of which is that the first segment of the network won’t even run high speed trains until the entire system is built). It’s going to cost an eye-watering amount of money even to build that first section:

Between them, the federal government, municipals along the proposed route and an assortment of private investors are being asked to chip in $30 billion. A further $10 billion is to be raised by a bond issue that Californian voters approved in 2008. Anything left unfunded will have to be met by taxpayers. They could be dunned for a lot. A study carried out in 2008 by the Reason Foundation and the Howard Jarvis Taxpayers Association put the final cost of the complete 800-mile network at $81 billion.That is probably not far off the mark. Last week, the state’s Legislative Analyst’s Office came out with a damning indictment of the project’s unrealistic cost estimates and poor management. The bill this legislative watchdog put on the first phase of the high-speed rail project alone is $67 billion — and higher still if the project runs into trouble gaining route approval in urban areas.

If the latter number is correct, then the first phase of the system is clocking in at nearly $1 billion per mile. And this is the “cheap” section running through mostly thinly populated farming areas. If, somehow, the more expensive sections of the planned network don’t cost much more, the total construction bill will top $800 billion. The original plan had the entire system costing $43 billion.

Cost overruns are an expected part of major government construction projects, but that’s insane.

Next on the primary school curriculum: Minecraft

<voice style=”curmudgeon”>Back in my day, we didn’t have computers in the classroom. We had books. And we liked ’em. Kids these days are just spoiled, I tell you.</voice>

At the Columbia Grammar and Preparatory School, first and second grade computer teacher Joel Levin developed an experimental Minecraft teaching unit that was designed to let kids explore, build, and collaborate within the game. He wasn’t sure how it’d go over. Much to his surprise, the students took to Minecraft like they do to sniffing scented markers.

Levin allows his students to play in a modified Minecraft world that doesn’t include monsters. His classes aren’t so much focused on teaching kids to play Minecraft as they are on using Minecraft as a canvas for them to be creative with. In one situation, Levin had to take animals out of the game because students were just killing them all over the place, which wasn’t in the spirit of his lessons.

Making light: are LED flashlights now “tacticool”?

Filed under: Randomness, Technology — Tags: , , — Nicholas @ 09:51

Chris Dumm has a bit of fun reviewing an LED flashlight:

Remember back when Mag-lite was the last word in aircraft-grade aluminum illumination? Those old incandescent Mag-Lites weren’t any brighter than ordinary flashlights, but their indestructible machined-aluminum bodies made them the choice of police, private security, Elvis and burglars. They were “tacticool” before people had a chance to learn to hate that word. The longer D-cell Mag-lites resembled aluminum billy clubs; they delivered a more devastating blow than any Monadnock PR-24 police baton ever could. Despite their size and weight, however, they still weren’t all that bright.

Then new technology arrived in the form of noble gas (Xenon bulbs) and heavy metal (Lithium batteries). SureFire and Streamlight built flashlights bright enough to temporarily blind and disorient a target without having to bash his brains in with five D-cell batteries wrapped in an aluminum Little League bat. And they were tough enough to drown, drop and attach to the hardest-kicking riot shotguns in the SWAT unit’s arsenal without fizzling out at the worst possible moment.

The new flashlights were rugged, dazzlingly bright and incredibly compact. Their only drawbacks: astronomical prices (for lights, bulbs, and batteries) and battery run-times of one hour or less. They quickly became the law enforcement standard, until LED technology took the lead and never looked back.

If you take typography seriously, you will surely go mad

Filed under: Humour, Technology — Tags: , , — Nicholas @ 15:51

Frequent commenter Lickmuffin sent in this link with the subject line “This is amusing AND SPOT ON!”.

This is freaking me out today. You see, I hardly look at my calendar date on the iPhone. But today I did. I looked at that pixel-perfect, beautiful Retina screen and this problem got instantly into my eye, like a white hot scalpel pinching through my retina until it reached the back of my skull.

See what I mean? Can you see IT? The 1 is off center. Instead of being optically centered, it’s geometrically centered. So it just looks wrong. Really, what happened there, Steve? Where did all that love for typography and attention to detail go? Out the fucking window of your silver Merc, that’s where.

Perhaps this is some kind of cruel April Fools joke from Cupertino. Maybe they are all at the office, hahahing at their clever joke. OK. I don’t find it fucking funny, but I understand your desire to torture your users.

But rather than leaving it there, whimpering, Lickmuffin was suddenly seized with a typographical fit:

Well, the “all phones have it wrong” answer might be correct. [Name] sent me the Gizmodo link through Skype, and I went on and on about why the 1 is off:

[2:10:58 PM] Lickmuffin: The 1 is off centre because they are centering on the width of the entire character — that serif off to the left with no serif on the right of the 1 makes the whole character appear off-center.

[2:13:46 PM] Lickmuffin: The “wrong” version 1 has about 44 pixels on either side of it, measured on the left from the edge of the white box to the serif, and on the right from the edge of the white box to the body of the 1. I say “about” because how you measure depends on whether or not you include the aliasing in the character.

[2:14:26 PM] Lickmuffin: In the “wrong” illustration, the 1 is off-center — it measures 41 pixels from the white box border on the left, and 49 pixels from the white box border on the right.

[2:15:56 PM] Lickmuffin: What the author is complaining about is common — graphical apps tend to base centering on overall character width. For example, when I create callouts in an illustration that have a number in a circle, simply centering the number in the circle will not always look right: the 1 is usually off, especially with sans-serif fonts. The graphics apps center on the width of the 1 as an object, not on the “visual center” of the character that would make it look right.

[2:18:49 PM] Lickmuffin: There are ways to fix this — fonts can carry information called “metrics” that help align fonts when they are placed together. Most often, metrics are used to adjust side-by-side spacing of characters by nudging characters closer together when they fit together. For example: WA Here the app (or the font) would nudge the W and A together. In the case of the 1, metrics could tell apps to center the character on an imaginary centre line, rather than on the actual centre line determined by the character’s width.

[2:19:01 PM] Lickmuffin: Fonts are F A S C I N A T I N G !

Yes, I know that the dongle on the “1” is not a serif — it’s actually part of the “stroke” of the letter. But you know what I mean.

Humph.

After his collapse, I understand that Lickmuffin is now lying down quietly in a darkened room with no visible letters or numbers. Perhaps he will recover, in time.

Memristor breakthrough

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

A report at The Register talks about HP’s new leads in the development of the “memristor”:

HP scientists have made a breakthrough in the development of memristors, a fundamental circuit type that looks increasingly likely to replace NAND flash and possibly DRAM.

Essentially, they’ve figured out the physical and chemical mechanisms that make memristors work.

“We were on a path where we would have had something that works reasonably well, but this improves our confidence and should allow us to improve the devices such that they are significantly better,” the leader of the HP research team, R. Stanley Williams, told IDG News.

Memristors are the fourth fundamental type of passive circuitry, along with the resistor, capacitor and inductor. Like flash, memristors are nonvolatile — they “remember” their state when power isn’t applied to them.

The core advantage of memristors is that they can theoretically achieve speeds 10 times that of flash at one-tenth the power budget per cell. They can also be stacked, enabling exceptionally dense memory structures.

Of course, this is all still in the research lab, so don’t expect to see memristor technology show up in your next tablet or smartphone. It could be several years before the new tech becomes widely available.

Josh Rosenthall tries to figure out who is behind the iOS developer patent troll

Filed under: Law, Technology — Tags: , , , — Nicholas @ 13:15

It’s not absolutely definitive, but it looks as if Nathan Myhrvold former Microsoft CTO and the founder of Intellectual Ventures might be the man:

It’s been confirmed today that a company called Lodsys recently sent out a number of letters to independent iOS developers, including James Thompson — the developer of PCalc — and Dave Castelnuovo, creator of Pocket God , informing them that their use of in-app purchases in iOS infringes upon on this particular patent. Of course, Lodsys is going after small developers who lack the resources of larger development companies to fight back, presumably to frighten them into striking a licensing deal as soon as possible.

So who exactly is behind this unabashed case of patent trolling?

Well, we did a little leg work and though we can’t say with 100% certainty who is pulling the strings, it’s looking a lot like Intellectual Ventures is behind this disgraceful lawsuit.

Intellectual Ventures was founded in part by former Microsoft CTO Nathan Myhrvold. The company’s business model is simple — it purchases and applies for a ton of patents. It then licenses out those patents to others under the threat of litigation coupled with a promise not to sue if a deal is struck.

So let’s go through the chain of patent ownership.

A disturbing possible future: nanolaw

Filed under: Economics, Law, Media, Technology — Tags: , — Nicholas @ 12:48

Paul Ford writes about a morning in the near future:

My daughter was first sued in the womb. It was all very new then. I’d posted ultrasound scans online for friends and family. I didn’t know the scans had steganographic thumbprints. A giant electronics company that made ultrasound machines acquired a speculative law firm for many tens of millions of dollars. The new legal division cut a deal with all five Big Socials to dig out contact information for anyone who’d posted pictures of their babies in-utero. It turns out the ultrasounds had no clear rights story; I didn’t actually own mine. It sounds stupid now but we didn’t know. The first backsuits named millions of people, and the Big Socials just caved, ripped up their privacy policies in exchange for a cut. So five months after I posted the ultrasounds, one month before my daughter was born, we received a letter (back then a paper letter) naming myself, my wife, and one or more unidentified fetal defendants in a suit. We faced, I learned, unspecified penalties for copyright violation and theft of trade secrets, and risked, it was implied, that my daughter would be born bankrupt.

But for $50.00 and processing fees the ultrasound shots I’d posted (copies attached) were mine forever, as long as I didn’t republish without permission.

How many e-books do you need to read to make your reading device economical?

Filed under: Books, Economics, Media, Technology — Tags: , , , — Nicholas @ 13:01

Dark Water Muse does the math for you:

In this piece DWM does not explore other possible ways that a tablet does things differently to a smart phone, net book, laptop or desktop computer. This is not a general review of tablet capabilities. It can be considered an update to DWM’s eReader versus Book piece [Ed: linked to from this post last week] with emphasis on the cost of the use of the tablet as an eReader.

Since DWM is focused on eReading then cost is an influential factor when considering any eReader device.

If you trust DWM to do the math and you don’t want to review DWM’s work (included further below in the section entitled “The Math”) then you can read the results in the Table #1: comparison of relative eReading costs below.

If we assume the average book price is $20 and eBooks are discounted by 40% (a gracious discount from DWM’s experience) then we get the following equation for N, the number of eBooks you must purchase and read on your new device to ensure you’re not paying more for the content you could have read as a book:

N = cost of device / $8

Table #1: comparison of relative eReading costs: The following table indicates the number of books N you must read on the corresponding eReader on the market today (prices taken from the web as of May 15, 2011) in order that the cost of the device does not drive up the cost of eBooks you read.

Would you fly in a glass airplane?

Filed under: Science, Technology — Tags: , — Nicholas @ 08:24

If Professor William Johnson is successful with the new process, you may see lots of structural glass in use:

A new breakthrough in superspeed pulse mould technology will allow aeroplanes, mobile phone casings and suchlike to be made out of a miraculous type of glass which is as tough as metal, according to the inventors of the new process.

So-called “metallic glass” has been well known since 1960 and has been in industrial production since the 1990s. It is a metal alloy, but one with the disordered structure of glass — not formed into crystals the way most metals are.

The crystalline structure of metal is a disadvantage, making it weak. Unfortunately, ordinary glasses — while strong and rigid — generally crack and shatter easily. What’s wanted is a metallic glass, made of metal but with a non-crystalline structure like window glass. This won’t crack or fracture, but will be much stronger than an equivalent object made of ordinary metal.

[. . .]

“We uniformly heat the glass at least a thousand times faster than anyone has before,” says William Johnson, engineering prof at Caltech.

Using this method the metalglass is heated up, moulded and cooled to solid again before crystals have any chance to form: the new part is still metalglass, not rubbishy regular metal.

“We end up with inexpensive, high-performance, precision parts made in the same way plastic parts are made — but made of a metal that’s 20 times stronger and stiffer than plastic,” boasts Johnson.

QotD: The instinctive reaction to progress

Filed under: Humour, Media, Quotations, Technology — Tags: , , — Nicholas @ 12:39

I suppose earlier generations had to sit through all this huffing and puffing with the invention of television, the phone, cinema, radio, the car, the bicycle, printing, the wheel and so on, but you would think we would learn the way these things work, which is this:

1) everything that’s already in the world when you’re born is just normal;

2) anything that gets invented between then and before you turn thirty is incredibly exciting and creative and with any luck you can make a career out of it;

3) anything that gets invented after you’re thirty is against the natural order of things and the beginning of the end of civilisation as we know it until it’s been around for about ten years when it gradually turns out to be alright really.

Apply this list to movies, rock music, word processors and mobile phones to work out how old you are.

Michael Geist: the “Lawful Access” legislation does not criminalize hyperlinking

Filed under: Cancon, Law, Liberty, Technology — Tags: , , , — Nicholas @ 12:16

At least, on a reasonable person’s reading of the proposed law, it doesn’t criminalize hyperlinks to material that “incites hatred”:

The source of the latest round of concern stems from the Library of Parliament’s Parliamentary Information and Research Service legislative summary of Bill C-51. On the issue of hyperlinking, it states:

Clause 5 of the bill provides that the offences of public incitement of hatred and wilful promotion of hatred may be committed by any means of communication and include making hate material available, by creating a hyperlink that directs web surfers to a website where hate material is posted, for example.

I must admit that I think is wrong. The actual legislative change amends the definition of communicating from this:

“communicating” includes communicating by telephone, broadcasting or other audible or visible means;

to this:

“communicating” means communicating by any means and includes making available;

The revised definition is obviously designed to broaden the scope of the public incitement of hatred provision by making it technology neutral. Whereas the current provision is potentially limited to certain technologies, the new provision would cover any form of communication. It does not specifically reference hyperlinking.

Michael is much more informed about this issue than I am, so I find his confidence as a welcome balm to all the concern raised about this issue. The bill itself, of course, remains a civil liberty disaster in other ways, even with this issue addressed:

As I have argued for a long time, there are many reasons to be concerned with lawful access. The government has never provided adequate evidence on the need for it, it has never been subject to committee review, it would mandate disclosure of some personal information without court oversight, it would establish a massive ISP regulatory process (including employee background checks), it would install broad new surveillance technologies, and it would cost millions (without a sense of who actually pays). Given these problems, it is not surprising to find that every privacy commissioner in Canada has signed a joint letter expressing their concerns.
