A report on phasing out nuclear power in Sweden

Filed under: Economics, Environment, Europe, Politics, Technology — Tags: , , , , — Nicholas @ 04:00

It may make politicians and activists feel empowered and righteous, but it has negative aspects that don’t seem to get the same level of attention as the “feel good” rhetoric does:

Nuclear power faces an uncertain future in Sweden. Major political parties, including the Green party of the coalition-government have recently strongly advocated for a policy to decommission the Swedish nuclear fleet prematurely. Here we examine the environmental, health and (to a lesser extent) economic impacts of implementing such a plan. The process has already been started through the early shutdown of the Barsebäck plant. We estimate that the political decision to shut down Barsebäck has resulted in ~2400 avoidable energy-production-related deaths and an increase in global CO2 emissions of 95 million tonnes to date (October 2014). The Swedish reactor fleet as a whole has reached just past its halfway point of production, and has a remaining potential production of up to 2100 TWh. The reactors have the potential of preventing 1.9–2.1 gigatonnes of future CO2-emissions if allowed to operate their full lifespans. The potential for future prevention of energy-related-deaths is 50,000–60,000. We estimate an 800 billion SEK (120 billion USD) lower-bound estimate for the lost tax revenue from an early phase-out policy. In sum, the evidence shows that implementing a ‘nuclear-free’ policy for Sweden (or countries in a similar situation) would constitute a highly retrograde step for climate, health and economic protection.

Published on 10 Jun 2012

This six-part, three-hour, BBC TV series aired in 1997. I presented and co-wrote the series; it was directed by James Muncie, with music by Brian Eno.

The series was based on my 1994 book, HOW BUILDINGS LEARN: What Happens After They’re Built. The book is still selling well and is used as a text in some college courses. Most of the 27 reviews on Amazon treat it as a book about system and software design, which tells me that architects are not as alert as computer people. But I knew that; that’s part of why I wrote the book.

Anybody is welcome to use anything from this series in any way they like. Please don’t bug me with requests for permission. Hack away. Do credit the BBC, who put considerable time and talent into the project.

Historic note: this was one of the first television productions made entirely in digital — shot digital, edited digital. The project wound up with not enough money, so digital was the workaround. The camera was so small that we seldom had to ask permission to shoot; everybody thought we were tourists. No film or sound crew. Everything technical on site was done by editors, writers, directors. That’s why the sound is a little sketchy, but there’s also some direct perception in the filming that is unusual.

Thinking about realistic security in the “internet of things”

Filed under: Technology — Tags: , , , , , — Nicholas @ 02:00

The Economist looks at the apparently unstoppable rush to internet-connect everything and why we should worry about security now:

Unfortunately, computer security is about to get trickier. Computers have already spread from people’s desktops into their pockets. Now they are embedding themselves in all sorts of gadgets, from cars and televisions to children’s toys, refrigerators and industrial kit. Cisco, a maker of networking equipment, reckons that there are 15 billion connected devices out there today. By 2020, it thinks, that number could climb to 50 billion. Boosters promise that a world of networked computers and sensors will be a place of unparalleled convenience and efficiency. They call it the “internet of things”.

Computer-security people call it a disaster in the making. They worry that, in their rush to bring cyber-widgets to market, the companies that produce them have not learned the lessons of the early years of the internet. The big computing firms of the 1980s and 1990s treated security as an afterthought. Only once the threats—in the forms of viruses, hacking attacks and so on—became apparent, did Microsoft, Apple and the rest start trying to fix things. But bolting on security after the fact is much harder than building it in from the start.

Of course, governments are desperate to prevent us from hiding our activities from them by way of cryptography or even moderately secure connections, so there’s the risk that any pre-rolled security option offered by a major corporation has already been riddled with convenient holes for government spooks … which makes it even more likely that others can also find and exploit those security holes.

… companies in all industries must heed the lessons that computing firms learned long ago. Writing completely secure code is almost impossible. As a consequence, a culture of openness is the best defence, because it helps spread fixes. When academic researchers contacted a chipmaker working for Volkswagen to tell it that they had found a vulnerability in a remote-car-key system, Volkswagen’s response included a court injunction. Shooting the messenger does not work. Indeed, firms such as Google now offer monetary rewards, or “bug bounties”, to hackers who contact them with details of flaws they have unearthed.

Thirty years ago, computer-makers that failed to take security seriously could claim ignorance as a defence. No longer. The internet of things will bring many benefits. The time to plan for its inevitable flaws is now.

Sarah Hoyt on being a time-traveller

Filed under: Europe, Technology — Tags: , , , — Nicholas @ 02:00

Earlier this month, Sarah Hoyt explained how a time-traveller from the (recent) past might be able to handle the changes encountered on visiting our modern world:

Yesterday some point was raised about how an early twentieth century person would react to the modern day.

Well, give them some years to adapt. I know. You see, I am a time traveler.

I think I have mentioned in the past that I was reading a book on the Middle Ages (the Time Traveler’s Guide to the Middle Ages, I think) and kept coming across things that I went “so?” on. Because they were the same conditions I grew up in.

It’s hard to explain, truly, because we had buses and cars (not many cars. For instance there were two vans and one car in the village. When I had a breathing crisis in the middle of the night (every few months or so till I was six) we had to knock on the door of the grocer across the street who — poor man, may he rest in peace, he died with Alzheimer’s — is as responsible as my parents for my still being here. He would throw on clothes at any hour of the day or night and drive us to emergency in the city, then wait with my parents until he found out if I’d be sent back home or kept on oxygen.

We also had telephones. In the grocery store. If something dire happened to one of the relatives overseas, they’d call, and so when we got the knock on the door and “call for” we knew it was bad news. Only worse news was a telegram. Mind you, my brother used that phone to call in song requests to request programs on the radio. (Programa de pedidos.)

Oh, yeah, we had radios. Everyone had a radio, even my grandparents, and had had them from the beginning of the century. There were dead tube radios in the attics, which is how I built myself my first radio. (“Dad, I want a radio.” “Good, you can have one.” And then he went back to reading Three Men In A Boat. I’m not actually joking.)

And then there were televisions. Well, every coffee shop had a TV, which is how they attracted the after-dinner crowd who, for cultural reasons, were mostly male. Then again the nearest coffee shop was a mile away. Through ill-lit streets. So, yeah.

My godmother and the housekeeper for the earl’s “farm house” catercorner from us had TVs. We often went to watch TV with the housekeeper, when the earl and his family wasn’t in (which was 99% of the time.) And all I have to say about my godmother’s door pane is that she really shouldn’t have gone on vacation at the time of the moon landing. And besides we cleaned up and left her money for the replacement. (Sheesh.)

[…]

I not only didn’t see a dishwasher till I was 12 (I think) but, having heard of them, I imagined them kind of like the robot diners in Simak. Arms come out the wall and wash dishes.

I was by no means the person from the most backward environment to become an exchange student. I certainly didn’t come from as backward a place as my host-parents expected (look, host-mom was descended from Portuguese. What she didn’t realize was that it had changed since her grandma’s stories.) They showed me how to flush the toilet…

However there were myriad culture shocks. The all-day TV, for instance. (I watched for two days solid, then decided it wasn’t my thing.) But mostly, at that time, the culture shock was the prosperity. My host mother bought a small TV for the kitchen on a whim, at a time when, in Portugal, you’d still have to save for years to buy ANY TV. Or the things considered necessary. We had patio furniture, though I don’t think anyone but me EVER went outside. (Not to blame them. Ohio has two seasons: Deep Freeze and Sauna.)

The refrigerator. When I came over we had a fridge. We got a fridge when I was ten. But a) it was the size of a dorm fridge. b) mom was still in the habit of shopping every day. So the morning was devoted to shopping for the food for lunch/dinner. The main thing we used our fridge for was ice-cubes, one per drink, because more than that might kill you.

My host family shopped once a week, and kept stuff in the deep freezer, so you didn’t need to run out to get food every day.

Apparently human ingenuity didn’t stretch as far as remote-controlled sex toys … until now!

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

Who would ever have thought of combining wireless computing with sexual appliances? Nobody, right? There’s no possible way that anyone could have even imagined such a thing could happen … otherwise this patent would not have been issued:

Alright, people, strap in and keep the laughter to a minimum because we’re going to talk dildos here. Specifically, remotely operated dildos, and other sex apparatuses, including those operated by Bluetooth connections or over the internet. It seems that in 1998, a Texan by the name of Warren Sandvick applied for a patent that casts an awfully wide net over remotely controlled sexual stimulation, specifically any of the sort that involves a user interface in a location different from the person being stimulated. You can find the patent at the link, but here’s the abstract:

    An interactive virtual sexual stimulation system has one or more user interfaces. Each user interface generally comprises a computer having an input device, video camera, and transmitter. The transmitter is used to interface the computer with one or more sexual stimulation devices, which are also located at the user interface. In accordance with the preferred embodiment, a person at a first user interface controls the stimulation device(s) located at a second user interface. The first and second user interfaces may be connected, for instance, through a web site on the Internet. In another embodiment, a person at a user interface may interact with a prerecorded video feed. The invention is implemented by software that is stored at the computer of the user interface, or at a web site accessed through the Internet.

Great, except that nothing in the above is an actual invention; it’s essentially an acknowledgement that a dildo could be controlled remotely and an attempt to lay claim to that function exclusively. The description of the art outlaid in the patent rests solely on the claim that sexual stimulation devices have always been either self-stimulation devices or that any remotely operated stimulation devices still required close proximity. But it all rests on what you consider a stimulation device.

Even before this patent was filed, there was a term for this kind of thing in use: teledildonics.

QotD: Master Foo and the Hardware Designer

Filed under: Humour, Quotations, Technology — Tags: , — Nicholas @ 01:00

On one occasion, as Master Foo was traveling to a conference with a few of his senior disciples, he was accosted by a hardware designer.

The hardware designer said: “It is rumored that you are a great programmer. How many lines of code do you write per year?”

Master Foo replied with a question: “How many square inches of silicon do you lay out per year?”

“Why…we hardware designers never measure our work in that way,” the man said.

“And why not?” Master Foo inquired.

“If we did so,” the hardware designer replied, “we would be tempted to design chips so large that they cannot be fabricated – and, if they were fabricated, their overwhelming complexity would make it be impossible to generate proper test vectors for them.”

Master Foo smiled, and bowed to the hardware designer.

In that moment, the hardware designer achieved enlightenment.

The rapid evolution of the US army helmet

Filed under: Military, Technology, USA — Tags: , — Nicholas @ 05:00

Strategy Page charts the increasing pace of change to the US army’s combat headgear:

Since 2000 combat helmet design has made enormous advances. The new helmets have increased protection (often against rifle bullets as employed by snipers) while becoming more comfortable to wear, more accommodating of accessories (especially personal radios and night vision gear) without becoming heavier. Combat helmets were long considered low-tech but that has changed since the 1980s. Creation of new materials plus advances in the design and construction of helmets have been accelerating, especially in the last decade. For example, the American ACH (Advanced Combat Helmet), as popular as it was after appearing in the 1990s, soon underwent tweaks to make it more stable. That was required because more troops were being equipped with a flip down (over one eye) transparent computer screen. The device is close to the eye, so it looks like a laptop computer display to the soldier and can display maps, orders, troop locations, or whatever. If the helmet jumps around too much it’s difficult for the solider to make out what’s on the display. This can be dangerous in combat.

The first modern combat helmets appeared during World War I (1914-18), with the U.S. adopting the flat, British design steel model and using it for 25 years. This was replaced by the M1 helmet in the early 1940s. This was the “steel pot” and liner system that lasted over four decades. The PASGT (Personnel Armor System for Ground Troops) replaced the M1 in the early 1980s and lasted twenty years. The ACH replaced PASGT by 2007 but by 2012 the ECH (Enhanced Combat Helmet) began appearing as a replacement. ECH, like ACH is built to take lots of accessories and is the version bought by police and emergency service organizations.

It was only in 2005 that the ACH began entering service. The Kevlar PASGT design was a third generation combat helmet, nicknamed the “Fritz” after its resemblance to the German helmets used in both World Wars. That German World War I design, which was based on an analysis of where troops were being hit by fragments and bullets in combat, was the most successful combat helmet in both world wars. This basic design was finally adopted by most other nations after the American PASGT helmet appeared in the 1980s. Most of the second generation helmets, which appeared largely during World War II, were similar to the old American M1 design. The fourth generation helmets, currently in service, use better synthetic materials and more comfortable design.

Would Reddit even be Reddit without the trolls?

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

Megan McArdle warns that “cleaning up” Reddit might end up killing the patient:

On Monday, when I wrote about the travails of Ellen Pao at Reddit, I noted that cleaning up the troll-infested caves of its vast ecosystem will not be an easy task for anyone. Its freewheeling, “anything goes” culture is a big part of its appeal to users, and the large number of users is a big part of Reddit‘s appeal to investors. It’s also worth noting that this approach is substantially cheaper than trying to keep a close eye on Reddit‘s ever-expanding universe of subreddits.

But Reddit really seems to want to tidy things up a bit, or at least force the trolls down to the basement where they won’t frighten the visitors. Steve Huffman, a Reddit co-founder who is returning as Pao’s successor, has announced that the company will continue to take steps to curtail undesirable content. Potentially offensive forums will require users to opt in, and anything that “harasses, bullies, or abuses” will be entirely off limits. So a forum whose title is a vile racist slur will be reclassified for opt-in status. But the “Raping Women” forum will be banned outright.

Huffman is laying out some much clearer guidelines than Pao did, which is a good first step (and exactly what I said Pao should have done). On the other hand, that’s no guarantee that this will prevent users from staging a mass exodus.

Catch the last flying Vulcan before September

Filed under: Britain, History, Military, Technology — Tags: , , , — Nicholas @ 02:00

As I’ve reported before, the very last of the Vulcan bombers able to take to the air will be retiring this year. Stuart Burns and Lewis Page have the details:

Visit a British air show before September and it’s possible you’ll get the opportunity to witness the last Vulcan bomber in flight — and this is definitely the last year you’ll get the chance, this time.

Alongside the staple leather-clad wing-walking ladies, the Battle of Britain Memorial Flight, simulated Apache attack-chopper scenarios and Red Arrows displays, you may find XH558 — now owned and flown by charity Vulcan to the Sky Trust, funded by charitable donations and Lottery cash.

The Vulcan holds a very special place in the hearts of many, not just for that unmistakable shape but because it functioned as a basic but wholly British nuclear deterrent early on in the Cold War.

Such was its frontline status and iconic image, the Vulcan was used by James Bond scriptwriters and given generous screen time in Thunderball (1965) — in which the V-bomber is hijacked by SPECTRE resulting in the loss of two nukes, which Commander Bond must then retrieve.

In the real world the Vulcan’s only combat action came in 1982, as part of the Falklands War. The “Black Buck” raids in which Vulcans — supported by a large fleet of aerial tankers — travelled all the way from Ascension Island to attack the Falklands held the longest-distance combat bombing record for nine years until the USAF took the top spot with B-52 raids in the 1991 Gulf War.

Standing as I did at the Cosford Airshow — one of those last displays — just few hundred yards from XH558, with its engines running at full tilt, you knew it was something special. The ground shook and your stomach throbbed as this mighty aircraft passed overhead.

To understand the reasoning behind the creation of the Vulcan you need to know the backstory about the freezing of the nuclear relationship between the UK and the US after World War II. When the bombs dropped on Nagasaki and Hiroshima, the war entered its final phase. Unfortunately, so did the nuclear relationship between the UK and the US.

The US, wanting to keep all the nuclear toys for itself, passed the McMahon Act — officially the Atomic Energy Act of 1946 — forbidding the transfer of nuclear knowledge or technology to any country, even those former allies (Britain and Canada) that helped develop the bombs which had been dropped on Japan.

The case for encryption – “Encryption should be enabled for everything by default”

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

Bruce Schneier explains why you should care (a lot) about having your data encrypted:

Encryption protects our data. It protects our data when it’s sitting on our computers and in data centers, and it protects it when it’s being transmitted around the Internet. It protects our conversations, whether video, voice, or text. It protects our privacy. It protects our anonymity. And sometimes, it protects our lives.

This protection is important for everyone. It’s easy to see how encryption protects journalists, human rights defenders, and political activists in authoritarian countries. But encryption protects the rest of us as well. It protects our data from criminals. It protects it from competitors, neighbors, and family members. It protects it from malicious attackers, and it protects it from accidents.

Encryption works best if it’s ubiquitous and automatic. The two forms of encryption you use most often — https URLs on your browser, and the handset-to-tower link for your cell phone calls — work so well because you don’t even know they’re there.

Encryption should be enabled for everything by default, not a feature you turn on only if you’re doing something you consider worth protecting.

This is important. If we only use encryption when we’re working with important data, then encryption signals that data’s importance. If only dissidents use encryption in a country, that country’s authorities have an easy way of identifying them. But if everyone uses it all of the time, encryption ceases to be a signal. No one can distinguish simple chatting from deeply private conversation. The government can’t tell the dissidents from the rest of the population. Every time you use encryption, you’re protecting someone who needs to use it to stay alive.

Modern photography … can you believe your lyin’ eyes?

Filed under: Media, Technology — Tags: , , , — Nicholas @ 05:00

Michelle Orange on the ways that photography can mislead and even change reality:

It may be that some of the great philosophical work of our time is taking place, hidden and unheralded, in the field of image forensics. Where but under the scrutiny of digital experts who draw a line separating false representations of the world from truthful ones are contemporary questions of perception and reality brought so keenly to bear? Who but these detectives of the real pursue as explicitly — as intricately — our crime wave of the fake, the contrived, the uncanny, the exponential image? With exquisite, singular focus, photo forensics engages the conundrum that photographic technology has tilted toward, steadily but ever more frankly, since its inception over 150 years ago: Does reality have a tipping point?

Dangling from the cliff edge of that question is the World Press Photo competition. In recent years the annual competition, which recognizes images submitted by photojournalists working across the globe, has dissolved into chaos, recrimination and a round of post-mortem soul-searching. Earlier this year, the WPP was forced to disqualify 22 percent of the competition’s finalists after forensics experts determined that certain images had been altered or manipulated beyond the currently accepted industry standard. This almost triples the number of disqualifications from a year earlier, suggesting a certain forward momentum, a trend larger and more fearsome than any set of standards.

Swedish photographer Paul Hansen won the 2013 World Press Photo competition with an image of a Gaza City funeral procession, led through an alley by men bearing the shrouded bodies of two children killed in an Israeli airstrike. Separate from the horror it depicts, with its fish-eye depth of field, stark figuration and stony matte light, the photo meets the eye as unreal. Complaints in this vein led to an investigation of the image, specifically its manipulation of tone — a quality central to photography’s evolving grammar of realism. Somehow both a beautifying tool and, in the right hands, possessed of the very texture of reality (as every Instagram filter maven knows), tone is transformative. For that reason, “excessive toning” is against WPP rules; Hansen said he adjusted tone only to balance uneven light, “in effect to recreate what the eye sees.” Ultimately, Hansen retained his prize: the judges stood behind what they saw, though it would appear their eyes prefer altered images a good portion of the time.

A bad day for the space program

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

In National Review, Taylor Dinerman discusses the bad news from SpaceX and what it means for the space program:

June 28 was Elon Musk’s 44th birthday, and he had hoped to celebrate with a successful launch of the SpaceX Falcon 9 rocket. It would be carrying a Dragon capsule full of supplies for the International Space Station (ISS), under the Commercial Orbital Transportation Services contract he signed with NASA back in 2006.

Musk had also hoped that once the Dragon capsule was well on its way to the space station, the Falcon’s first stage would return to Earth’s surface for a powered landing on a barge off the coast of Florida. A successful flight would have been a major step toward building a reusable launch vehicle, which could radically reduce the cost of getting payloads into orbit.

Instead, the Falcon 9 exploded a few minutes after leaving the launch pad.

It has been a rough time recently for ISS logistics. In October an Antares rocket launched from Virginia by Orbital Sciences blew up, and in April a Russian Progress supply capsule was lost when its Soyuz launcher malfunctioned. NASA says that there are enough supplies onboard the ISS to last until October. If this summer’s planned launch of a Japanese HTV supply capsule goes wrong, things could get dicey.

Elon Musk – high tech messiah or grasping crony capitalist?

Filed under: Business, Environment, Government, Technology, USA — Tags: , , , , — Nicholas @ 03:00

Sean Noble says that the subsidies Elon Musk’s high-tech Tesla and Solar City firms are much higher than he implies:

Tesla, SpaceX, and Solar City head Elon Musk lashed out at the Los Angeles Times following an article that totaled up all the government support that his three-headed corporate-welfare monster receives. The number the Times reported was nearly $5 billion in combined support for his companies, including subsidies for those who purchase Musk’s products, such as the high-priced solar panels of Solar City and the supercars of Tesla.

Musk responded by arguing, “If I cared about subsidies, I would have entered the oil and gas industry.” He further asserted that his competitors in the oil-and-gas industry haul in 1,000 times more in subsidies in a single year than his companies have received in total. Such statements reveal that Musk seems to care as little for facts as he purports to care about the taxpayer dollars propping up his various businesses.

Earlier this year, the U.S. Energy Information Administration (EIA) released the most recent data available regarding energy subsidies provided by the federal government. The data, covering the year 2013, broke down total taxpayer subsidies across the different sectors of the energy industry. While fossil fuels did enjoy some government support through various direct expenditures, tax credits, and R&D programs, the data stands in sharp contrast to Musk’s claims.

Data from the EIA report, combined with numbers from an anti-oil advocacy group regarding state-level government support, reveals that total state and federal support for the oil-and-gas industry is no more than $5.5 billion each year. As stated, Musk’s companies combine for $5 billion in subsidies, a number that he has yet to dispute. Clearly, the difference is much smaller than Musk’s outlandish 1,000-to-one claim.
