Product idea: guaranteed win lottery tickets

Milan — Thu, 24 Jul 2008 22:02:31 +0000

While thinking idly about ways to tactfully pass money to people, I had an idea. A company could sell lottery tickets (probably of the scratch-and-win sort) that are guaranteed to pay out specific amounts. You would buy them for the face value plus a service fee. They could be issued in denominations running from $10 or so up to thousands.

They would look like ordinary tickets, and could be redeemed at places that sell scratch-and-win tickets. The merchant would simply be compensated by the company. Even better, the company could buy guaranteed winner tickets from the normal ticket issuers. That way, they would be available in the same brands as tickets sold in normal shops, diminishing suspicion and allowing buyers to choose something suitable for the recipient.

This could be:

A way to help a struggling friend of family member without making them feel guilty.
A way to convince someone feeling down on their luck that things are turning around.
Practical jokes of various sorts.
Less benevolently, as a semi-covert means of exchanging money.

Could there be any other uses? Would people actually buy such a thing? Would lottery regulators ever permit them?

Scarce resource conservation optimization

Milan — Thu, 24 Jul 2008 11:14:43 +0000

There is a catch-22 involved in some forms of resource planning. Take, for example, helium (as discussed recently). As of now, we only know of one place from which to get it - certain natural gas deposits. We have no idea where, or if, it might be found elsewhere.

One perspective is to say: “For all we know, this is all the helium we will ever be able to access on Earth. We should avoid excessive (airships) and frivolous (party balloons) uses, and save the stuff for cooling sophisticated electronic equipment and so forth.” One could add to this: “If we ever come across a big new source, or an unlimited source, we can reevaluate the prohibition.”

The trouble here is the reduced incentive to find new supplies. There have surely been countless historical cases where scarcity has generated rising prices which has in turn (a) led to the discovery of new sources of raw material (b) led to new techniques of production and (c) led to less intensive patterns of usage. The conservation mindset could impede these. Our solution may be akin to a policeman adrift on a lifeboat with a highly trained and valuable bloodhound. Every day, he is presented with a choice to either use the dog now as a collection of calories, or save it for a more valuable use in a future that may never come. Of course, the situation with any particular resource is far more complex. Our present needs are less acute and singular, the uses of the thing are broader, and our opportunities for near-term and (likely) long-term substitution are usually higher.

At issue are factors including (1) the most critical use of the resource (2) the probability of a, b, or c taking place over any time period (3) the urgency of the present uses, etc. A rational calculation taking into account all these factors (and necessarily making educated guesses about future trends) is a daunting prospect. To what extent does the usefulness of helium in medical imaging affect how we should manage supplies? Will we soon develop technologies that require more or less of the stuff? Is there any entity that is actually capable of managing helium use?

Of course, such choices are rarely made explicitly. Typically, nobody has the power to control the allocation of a global resource. As such, they are used up heedlessly in response to the economic imperatives of the moment- ignoring the fact that the same material might have a far more valuable purpose down the road.

Green bonds in Canada

Milan — Wed, 23 Jul 2008 22:36:53 +0000

Emily Paddon, one of my friends and classmates from Oxford, is involved in a scheme to create green bonds in Canada. The initiative, which is part of the Action Canada Fellowship, aims to create a “government-backed financial instrument designed to engage the public by raising capital to accelerate renewable energy production.” The aim is to eliminate more than 25 million tonnes of carbon dioxide equivalent by 2020, at a cost of between $1 and $13 per tonne.

Innovative financing mechanisms will be a very important part of the transition to a low carbon economy. It will be interesting to see when the full details of this become available, and even more interesting when the bonds are available for purchase. Those aiming to both save for the future and help to save the future should take note.

Wall-E

Milan — Wed, 23 Jul 2008 11:46:39 +0000

The Wall-E trailer did not impress me. It made the film look cute and trite. Nonetheless, I was convinced to see the film by strong recommendations in various news sources and ongoing debates about its environmental messages.

The film is definitely well done: engaging and entertaining, emotive without being sappy. Some of the messages are indisputable: that resilience is a virtue (Wall-E has learned self-repair), that the planet is vulnerable, and that technology can isolate us from natural processes, making us unaware of the impacts we are collectively producing. Others are more dubious: that people ignore their environmental impacts because they are half-hypnotized by machines, rather than because it is convenient to do so, or that a simple imposition of will is sufficient to turn things around. The danger is less that robots will mutiny, and much more that we will be willing to make exceptional ecological sacrifices in order to keep our favourite machines running. It’s not that our creations will defy our will, it’s that we will refuse to temper our desires, whatever the long-term costs associated. Wall-E does make the second point (largely though the vehicle of the floating, near-helpless humans), but it gives a bit too much of a free pass on the first.

It seems fairly likely that this film is destined for the cannon of ‘environmental films for children,’ alongside stalwarts like The Lorax. It deserves the slot, combining old messages about conservation and the sanctity of life with the imagery of contemporary society. It also deserves to be widely seen, by children and adults. That is as much on account of the strong storytelling as anything else - the dialogue is minimal, but it is never the slightest bit tedious. The story is strong, the film is beautifully made, and it generates thought.

On a side note: the various nods to Apple were slightly amusing, rather than tacky. Wall-E’s startup noise will be familiar to anyone who has used a Mac, as is the whole styling of Eve. The original iMac ‘mice’ infesting the garbage heaps in space were also an entertaining touch. Of course, it is a bit ironic that the main object of desire in the film - the robot Eve that Wall-E pines after - is fundamentally modeled upon a much hyped consumer product.

[Update: 8:01am] Emily’s review is here.

Re-encrypting WiFi

Milan — Tue, 22 Jul 2008 22:18:36 +0000

Unfortunately, I had to shut down my open wireless network experiment. That is because I found three people within the span of two days who were both (a) criminal and (b) very stupid.

One thing to remember: if you are going to use open wireless networks to download illegal things, make sure you aren’t sharing your entire hard drive in read/write mode. Not only will the person running the network get wise to you without even needing to sniff packets, they will be able to remotely eliminate your ill-gotten files before banning you from the network. If they were so inclined, they could do much worse things to you.

I suppose I could set up a captive portal system using something like ZoneCD - thus providing scope for well behaved neighbours and passers by to use the network. That would, however, require acquiring and setting up a computer between my DSL modem and WAP. Since the two are presently integrated, the expense and bother would be even greater.

As is so always the case, a few bad apples have made it necessary to discontinue a good thing.

Consider helium conservation

Milan — Tue, 22 Jul 2008 11:10:56 +0000

All the helium on Earth arose from natural fission of uranium and thorium in the planet’s crust and mantle. We can access it only through certain natural gas deposits - many of them in Texas - which contain enough of the gas to make it possible to isolate. This is the helium of every high-voiced balloon prank, as well as of every MRI scanner and high temperature superconductor. About 1/4 of helium use is in cryogenic applications. Helium is ideal for such purposes, as it has the lowest boiling point of any known element.

What is not commonly appreciated is that, once these particular gas reserves are depleted, we will know of nowhere from which to get helium. Whatever helium is released into the atmosphere gradually rises through it, eventually drifting into interplanetary space. Despite all the helium being released by human beings, atmospheric concentrations have remained constant at around 5.2 parts per million.

We can produce minute quantities of helium through hydrogen fusion, of the kind that will eventually take place in the International Thermonuclear Experimental Reactor, but it will not be even close to the quantity that will be required to cool the superconducting magnets that will keep the plasma inside that device contained.

It would be particularly ironic if a long-hoped-for source of renewable energy (nuclear fusion) proved impractical not because of issues associated with energy levels of plasma containment, but because we had squandered the planet’s accessible supplies of coolant.

Mnemonics for Pi

Milan — Mon, 21 Jul 2008 22:33:57 +0000

The people who memorize thousands of digits of pi generally strike me as more inhuman than impressive - not at such tasks does the normal human mind excel. Nonetheless, being able to recall ten digits or so might allow you to win bets at geekier parties and, if that can be achieved painlessly, it may be worth doing.

Probably the best way to do so is with mnemonic techniques. You can get fifteen digits by using the number of letters in each word of the following phrase:

How I want a drink, alcoholic of course, after the heavy lectures involving quantum mechanics!

Many other examples, including an entire sonnet, are on the Wikipedia page for Piphilology.

The Dark Knight

Milan — Mon, 21 Jul 2008 11:41:39 +0000

Ordinarily, comic book movies are an exercise in the aggressive non-suspension of disbelief, for me. Whether internally criticizing absurd physics or ludicrous plot points, I generally entertain myself more despite them than through them. The Dark Knight was an exception.

I posit two major reasons for this. Firstly, it is a result of the character of the Batman universe. It exists at a larger scale than many fictional or comic universes and, as such, has more freedom to establish its own rules and expectations. It is much more Lord of the Rings than Spiderman, despite greater superficial similarities with the former. Gotham City simply differs enough from our world to make it a clear allegory, rather than reality with implausible supernatural additions and equally implausible smoothing over of plot progression (How do characters put things in place to appear at the middle of chaotic chase scenes? How does the Joker recruit and train people? Why can everyone use unfamiliar equipment instantly? Etc.) It takes a pretty good film to suppress such questions in my mind, and this one manages it notably well.

The second is simply that the acting and presentation are quite compelling. The over-the-top action sequences are less asinine than in many smasher films, and there are some decent character and thematic issues addressed. Probably more importantly, the film has a powerful aesthetic - one that even a fairly reluctant appreciator of alternative universes can respect. Where the later X-Men films felt tacky and emotionally overdone, the gritty and chaotic Batman style remains stubbornly consistent.

Of course, Batman’s moral code remains ludicrous. Simply refraining from actually killing people immediately and with your own hand seems like a bizarre form of self-limitation, when you are perfectly happy to set off massive explosions and otherwise indirectly kill large numbers of people. The film isn’t entirely divorced from point-scoring on contemporary political issues (such as the security value of mass surveillance), but it wears such garments in an accessory fashion, rather than serving as a vehicle for polemic.

On a side note, the film demonstrates the degree to which Hong Kong is itself an alternate universe, at least as viewed from the air. The place looks like Ghost in the Shell made flesh, and provides an almost visceral reminder of the rise of Asia - one that the upcoming Beijing Olympics will doubtless reinforce.

Al Gore’s solutions

Milan — Sun, 20 Jul 2008 22:23:38 +0000

Al Gore recently gave a highly interesting speech on the future of energy in the United States. None of the points made in it are especially new, but he does a good job of tying together a great many important themes.

Here are some key points:

Because of climate change, “the future of human civilization is at stake.”
“[T]here is now a 75 percent chance that within five years the entire [Arctic] ice cap will completely disappear during the summer months. This will further increase the melting pressure on Greenland.”
“We’re borrowing money from China to buy oil from the Persian Gulf to burn it in ways that destroy the planet. Every bit of that’s got to change… The answer is to end our reliance on carbon-based fuels.”
Solar, wind, and geothermal are large and critical future energy sources.
“I challenge our nation to commit to producing 100 percent of our electricity from renewable energy and truly clean carbon-free sources within 10 years.”
“[S]harp cost reductions now beginning to take place in solar, wind, and geothermal power — coupled with the recent dramatic price increases for oil and coal — have radically changed the economics of energy.”
The national grid must be updated to link areas rich in renewable energy to areas with high energy demand.
Plug-in electric cars will play an important role in balancing the load on the electrical grid.
“[W]e need to greatly improve our commitment to efficiency and conservation. That’s the best investment we can make.”
“I have long supported a sharp reduction in payroll taxes with the difference made up in CO2 taxes. We should tax what we burn, not what we earn.”
“[I]t is also essential that the United States rejoin the global community and lead efforts to secure an international treaty at Copenhagen in December of next year that includes a cap on CO2 emissions.”
“[W]e must move first, because that is the key to getting others to follow; and because moving first is in our own national interest.”

The 100% target is probably not going to happen - it would require scrapping every coal, gas, and oil power plant - but it is a worthwhile aspiration nonetheless. Even getting a significant portion of the way towards that goal in the timeframe mentioned would be a huge advance.

It would be very interesting to see what role he would personally play in advancing this sort of agenda within an Obama administration. An administration that made a determined effort to implement this sort of agenda would be transformative, and could do a great deal to spur global transformation.

Knives and Britain

Milan — Sun, 20 Jul 2008 11:12:10 +0000

I must admit, I find the ongoing debate about knives in the UK somewhat perplexing. The leader of the Conservative Party wants mandatory jail time for anyone caught carrying one. Editors at the BBC argue that the problem may be overblown. To me, it seems like what people are missing is the fundamental difference between knives and weapons. Obviously, a knife can be used as a weapon. So can a hammer, umbrella, or fork. While we rightly appreciate that it is illegitimate use of the latter that is problematic (and addressed through laws against assault, uttering threats, etc), it seems important to remember that use-as-a-weapon is aberrant, rather than to be expected.

At virtually all times, I have either one or two small folding knives on me: one on the SOG Crosscut on my keychain and a CRKT Kiss in my backpack. When I am travelling or going into the woods, I will often have a Swisstool X with me as well. Probably the most common uses of these are cutting food and paper, though each has been used in dozens of ways. Knives are ancient, highly versatile, and useful tools - one of the first technologies to differentiate the human species from less adaptive animals. Assuming that I am carrying either as a weapon strikes me as unfair, as well as a reversal of the presumption of innocence. The onus must be on the authorities to prove malicious intent, rather than upon the individual to prove their intentions benign.

On a side note, all of this is very different for guns, particularly handguns. The only plausible use for a handgun is as a weapon. One never goes on a picnic and regrets the lack of one. Restricting the ownership and carrying of guns is an entirely reasonable restriction, as a manifestation of their nature.

Carbon junkies and nicotine addicts

Milan — Sat, 19 Jul 2008 22:47:22 +0000

The comic in the July 12th issue of The Economist is quite a good one. It shows an American eagle, mouth crammed with cigarettes and a cigarette package labelled ‘Greenhouse’ in its talon, telling a tiger labelled ‘India’ and a dragon labelled ‘China’ that it is: “Time to cut back.” Both the tiger and the dragon also have mouths and fists crammed with smokes.

The tiger says to the dragon: “He wants us to follow his lead.” To which the dragon replies: “That’s what we have been doing.”

It does a good job of encapsulating the whole “you developed in a dirty way so we have the same right” argument, as well as the poisonous “there is no point in acting ourselves if other big emitters won’t do so” argument. The best answer to all this is:

The developed world does owe some assistance to the developing world, largely on the basis of the effects the latter will suffer because of the past emissions of the former.
Developing countries have an excellent opportunity to carry out the process of development in a more sustainable way than has been employed elsewhere.
Cutting back on fossil fuel use and greenhouse gas emissions is a temporary sacrifice, but a long-term boon. In the end, it will be the societies that do the best job of transitioning to a low-carbon future that will be the most successful in decades and centuries ahead.

Hopefully, the basic truth of those positions will be able to carry through into the ongoing global negotiations and we will have something big and meaningful to show for it at COP-15 in Copenhagen next year.

Cacophony

Milan — Sat, 19 Jul 2008 15:32:31 +0000

This morning, Emily, my mother, and I all woke to what sounded like somebody upstairs using a jackhammer on a hardwood floor. The whole house was vibrating, saturated with squealing and rattling noises.

A few minutes of pyjama-clad inquiries led me to the neighbour involved with the noise: “Oh, we’re just cutting some beams in the basement.”

Brain-thoughts, at that moment: “First thing in the morning? On a Saturday? With what sounds like an misfiring chainsaw?”

Promises of ‘just a few more minutes’ secured, back-to-bed trundling.

Brain-thoughts, just before returning to sleep: “Those aren’t the beams holding up this building, are they?”

Oh, it is too hot here…
