Debugging in the real world

Friday, July 30th, 2010

As part of my preparations for living in Zambia, I’ve had to have some vaccinations. One of the recommended vaccinations was Hepatitis B. Luckily, the UK National Health Service provides Hep B vaccinations for free. Unluckily, they also provide Hepatitis A vaccinations for free, and the two are delivered as a combined vaccine. I’ve already been vaccinated for Hep A, so I can’t have the combined shot. This means I have to have the single Hep B vaccine, which isn’t free.

It seems odd that having immunity to a disease should drive up my costs for getting vaccinated for another disease. It seems downright bizarre that my making it easier (or at least, no harder) for the government to deliver the free service should mean I have to pay. It would be fashionable at this point to rail against the fundamental inefficiency of government-provided healthcare.

But I don’t think that’s what’s happening here. The mistake the NHS seem to be making here looks like the same sort of mistake that is made every day by thousands of software developers. The set of rules for Hepatitis has a bug in it (no pun intended).

It seems to me that in this case the bug is a leaky abstraction. The obvious goal is to provide immunity to both diseases, and a policy of providing a combined vaccine looks from a high level as if it fulfils that goal. When the details of the policy are implemented, an obvious refinement is not to provide a combined vaccine to someone who’s already had one shot (whether this is a matter of health or cost-saving I don’t know, but it doesn’t affect the argument).

Obviously this is an over-simplification; looking at the world through the eyes of a programmer, things naturally form into shapes and idioms that are common currency to the techie. But I think this there’s something to be gained from seeing the world this way. When people try and build rule sets, they get things wrong. Not because they are stupid, or unwilling, or corrupted, or bureaucratic, but simply because creating perfect rule sets isn’t something that humans are naturally capable of.

Four things that are going to change whether the publishing industry likes it or not

Saturday, February 6th, 2010

It was an accident of circumstance that led the music industry to experience a major transformation, from selling objects to selling information, sooner than the book-publishing industry. Simplifying wildly, the fact that headphones are much cheaper to produce than screens is all that has held up the status quo in publishing for so long.

Currently some of the discussion in publishing centers on the fact that music is now sold in $1 downloads rather than $15 albums. But this too is an accident of circumstance. The length of a CD album is not a golden standard of the quantity in which people like to enjoy music, but one person’s personal taste: Sony vice-president Norio Ohga wanted a CD to hold the entire of Beethoven’s 9th symphony, and so for over a decade that is how we purchased our music.

Current commentary sometimes seems to imply that the music industry allowed the business model to be shifted to single-track purchases (to its cost) due to poor negotiation, and that the print industry might avoid making the same mistake. This is a delusion: certain changes in technology simply invalidate the old assumptions.

I expect the Amazon / Macmillan negotiation soap opera will resolve itself before long, but is in danger of drowning out discussion of the lasting shifts that the industry will inevitably go through. Here are a few of my predictions:

More competition with out-of-copyright works

In a physical book shop works that are out of copyright tend to sell for almost as much as recent releases. This is not unreasonable, since they still require editing, desigining and promoting, not to mention the cost of printing the physical book. Shelf space is a major cost in high street book shops, and costs no less when the work is out of copyright.

In a market for electronic books, some of these costs go away. The rest can be defrayed over a much longer period of time, since there is no opportunity cost to keeping books on the shelf. Competition with amateurish free copies will drive down the cost of a professionally-edited version to far below the cost of a new work, while still allowing publishers to turn a profit.

Most authors are not blessed with the wisdom of Marcus Aurelius, the wit of Jerome K. Jerome or the inventiveness of Arthur Conan Doyle (just three authors I’ve enjoyed for free on my Kindle). Of course the modern world has its own share of geniuses, and even those of middle rank can offer great value to readers by writing about the subjects that interest them, but it would be a sad world indeed if people didn’t capitalise on the opportunity to enjoy classic works for peanuts.

More flexibility in length of published works

It used to be that a book had to be of a certain length to be worth publishing. This is going to change, since the fixed costs of printing have gone away. The only question remaining is whether people will consent to pay small amounts for small amounts of content. There is no rational reason why not, but the field of paid content isn’t a shining example of rational consumer behaviour to date.

More competition from the back catalogue

The ‘long tail’ effect, where stock can diversify as shelving cost drops to zero, can flourish in the electronic market as the cost of warehousing drops out of the model. No book need ever again be out of print. This is going to help some authors and hurt others: books that have fallen from prominence aren’t necessarily bad, and if priced keenly they might prove a worthy substitute for recent publications at hardback prices.

More competition from the ‘gift economy’

Once you discard the requirement that books have to be printed on paper to be consumed, the barrier to entry to the market is much lower. Vast amounts of text in blogs, wiki articles and social network postings become readable in exactly the same circumstances as published books.

People who infer that this will drive the price of all textual content down to zero are unjustified in their conclusion and hopefully wrong. A well-researched, professionally-written and carefully-edited document is worth substantially more than an amateurish one, and a rational consumer will be prepared to pay more for it. However, for the portions of our reading time (hopefully not all) that are idle escapism, it may well be that the difference isn’t worth caring about.

Don’t shoot the messenger

I’m not saying the above out of ideology, but because I think the trends are inescapable, in direction if not in extent. More important is what won’t change: people will still exchange money for items that are of value to them. The lesson from the music industry’s experience is that the publishers that embrace the new rules and figure out how to turn them to their advantage will prosper.

Why Haiti? Why now?

Tuesday, January 26th, 2010

Before I start, let me say that the earthquake in Haiti was a tragedy, and the public response to it has been laudable. Nothing I say here is intended to undermine the generosity of those who stepped forward to donate. But I feel the aftermath exposes a worrying pattern.

A natural disaster befalls a certain part of the world, and people wring their hands over it. Soon this settles down and people devote their energies to providing aid: governments and NGOs swing into action, and the general public mobilise their best efforts to provide funds from T-shirts, concerts, bake sales and good old-fashioned donations. The sense of hopelessness is temporarily assuaged until news gets back that aid can’t get through: Haiti’s lack of infrastructure combined with the crippling effects of the quake mean that aid is blocked by sheer logistical difficulties—and we’re back to hand-wringing again.

Nobody likes to feel powerless. But if you want to prevent unnecessary deaths, then I have good news for you: it’s easier than you think. Around one million people die from malaria each year, and nearly two million from tuberculosis (TB). An incredible 36 million die each year from causes related to malnutrition (this number very likely overlaps with the numbers for malaria and TB). The vast majority of these deaths are preventable, and at surprisingly low cost, since the limiting factor isn’t the Herculean logistical task of getting emergency aid in through narrow transport channels already at maximum capacity—it’s simply lack of funds.

Haiti may not be getting all the help it needs right now, but it’s quite possibly getting all the help it can handle for the moment. Meanwhile, poverty hasn’t let up elsewhere in the world, and by the third day of the Haiti relief effort an equivalent number of preventable deaths had happened elsewhere in the world.

I don’t pretend to have any answers to global poverty, but I’d like to suggest two questions that could usefully guide our human desire to make the world a better place. Firstly, how can I target my giving to optimise the amount of suffering saved in the world? Secondly, how can I target my giving to be sustainable and continue to pay dividends over time? If we can satisfy these, then I don’t see what more can be asked of us.
