Edinburgh Trams: Perception vs Performance

Tram at Ingliston Park and Ride
Tram at Ingliston Park and Ride.

Edinburgh’s Trams may yet provide the ultimate test of perception over performance. I walked the entire route (by nearest footpath) on launch day, then rode the tram back. I preferred the walk. Read More

Scottish Tram Financing

Transforming Travel... or not. Edinburgh Tram's optimistic route plan.
Transforming Travel… or not. Edinburgh Tram’s optimistic route plan.

Some Edinburgh City councillors already privately refer to the city’s tram project as the problem that “cannot be named”. Much as actors refer to Shakespeare’s tragedy as “the Scottish play”, superstitions of bad luck now bedevil the production. A dramatic shift from the optimism that initially characterised the development of the Edinburgh tram, towards pessimism.

That which cannot be named is no longer just the failure of a flagship local transport policy. The issue has engulfed the City of Edinburgh Council, and now risks destroying local politics completely: Not only the existing administration, but public trust in local government decision-making.

Political heavy-weights, who normally shy away from the minutiae of local governance, are now offering parental guidance in public: Alistair Darling (local Member of Parliament, and former United Kingdom Chancellor and Secretary of State for Transport) described the option to borrow £231 million ($370 million) to complete the city centre section of the tram line as “absolute madness” – the local population would be saddled with vast debts. Days later, Graham Birse (chief executive of the influential Edinburgh Chamber of Commerce) called the decision to not complete the city centre section, “bonkers” – far fewer passengers would use a tram that did not serve the city centre adequately. Even Alex Salmond (Scotland’s First Minister) has become directly embroiled, struggling to contain calls for an immediate public inquiry to identify who is responsible.

Burn the witches! This Scottish tragedy is rapidly descending into farce. That would be unfortunate, because this particular local difficulty goes to the heart of the Scottish nationalist agenda: A desire for greater devolution of public funds to local level. More localised independent entities have fewer financial resources, so are less able to manage expensive, risky projects. Consequently policy ambitions also need to be scaled back. Such scale isn’t necessarily a problem – small can be beautiful. The problem lies in pretending to be big, when not.

This article introduces the concept of risk in tram (and similarly large public transportation and infrastructure) projects, chronicles the decisions that lead a relatively small local authority to need to find hundreds of millions of pounds to support a single project, and explores the implications for future policy-making, especially in the context of a more devolved Scotland.

Virtual Property, Rights, Riots and Governance

“Virtual property” popularly refers to virtual goods – items purchased for use or display within virtual worlds, online games, and social networking platforms (like Facebook). The term could equally apply to other cyberspace assets, like land in Second Life or Entropia. Even items acquired through the investment of time or expertise (rather than a specific currency exchange), like my Sea Turtle. If you use such simple definitions, property does not influence rights or governance: The virtual environment doesn’t substantively change anything in law. Contracts can still control the relationship between the people and organisations involved. Copyright still protects the underlying electronic and creative concepts. What’s all the fuss about?

The utopian ideals of some of the early internet pioneers are long since forgotten. More recent debates about the rights of avatars have been steam-rollered under “the tyranny of the End User Licence Agreement” (quoting Andres Guadamuz – although perhaps such an agreement is still more democratic than a unsigned contract with society). So who cares? Read More

Behind a Royal Wedding

Zara Phillips enters Cannongate Kirk.
Zara Phillips enters Cannongate Kirk.

The marriage of the Queen’s granddaughter, Zara Phillips, to Rugby player Mike Tindall has been widely reported, especially by the celebrity press. It has been referred to as “the other” royal wedding, for its stark contrast with the marriage of William and Kate (the Duke and Duchess of Cambridge) a few months before.

That contrast isn’t just in the status of those getting married – Zara being 13th in line to the British throne, William 2nd. William and Kate’s wedding was a public spectacle, with all the pomp and ceremony of state, while Mike and Zara’s was a “quiet” family affair. Unfortunately the later wedding still generated significant public interest, and the result was a bizarre clash of family and celebrity, privacy and publicity. Read More

Simon Kirby: The Language Organism

Language is a method of sharing thoughts. It is uniquely human: Many species communicate using pre-specified techniques, such as markings on a flower to direct bees, or gestures between mammals – but only humans have the flexibility of language. Language is, perhaps, the key evolutionary advantage the human race has over everything else on planet earth.

So how have we come to develop this trait?

That’s the question Simon Kirby has spent the last 21 years trying to answer, now assisted by one of the world’s leading research groups on the topic. Their research suggests that Darwin’s model of natural selection is not a terribly good explanation. Indeed our culture actually shields us from natural selection, making our genes progressively less important to language as we develop. Simon goes on to speculate that domestification (being buffered from purely survival instincts) is a key condition of the emergence of language.

Kirby’s evidence is especially interesting because, unlike Chomsky, he does not propose an innate underlying structure for the development of language. Such a dominance of unbounded cultural transmission would be both liberating and terrifying: Liberating because it suggests unrealised flexibility in language, especially forms enabled by future technology. Terrifying because (certainly from a relativist perspective, but arguably more widely) shared thought through language is what defines our very being.

This article is based on Simon’s well-attended inaugural lecture to the University of Edinburgh, presented on 22 March 2011. Read More

Systems of Curse and ZAM

The World of Warcraft ecosystem saw the final “big fansite” acquisition this week, with MMO-Champion bought by Curse Inc. Big meaning something that attracts millions of users each month. Curse have been using some of their $11 million of venture capital to buy up a variety of gaming fansites, including many popular WoW sites. But MMO-Champion is significant for 3 other reasons:

  • Corporate deal, not the “founder buy-out” traditionally commonplace among gaming fansites. MMO-Champion was previously owned by Major League Gaming, already a multi-million dollar enterprise (by comparison, $46 million funding).
  • Completes a duopoly (2 dominant businesses) in the core World of Warcraft “fansite” market – Curse and ZAM. While there are other large businesses and specialist niches on the fringe, none of those appear to be growing into the core WoW market.
  • Exposes an intriguing driver of this market structure: Systems costs – the underlying technology and support costs. Intriguing because these were crucial in determining the market structure of far more traditional sectors of the economy, like groceries.

This article analyses the latest acquisitions and discusses the unseen importance of systems costs. Read More

Thoughts on the Resolution of Nothing

I ponder nothing. Endlessly. Nothing in the intangible sense – the increasing dominance of things without physical form in society and economy. Nothing in the sceptical nihilistic sense – the “meaninglessness of existence”. Even the nothing inherent in the stupidity required for cleverness.

Nothing isn’t new. The problem baffled thinkers for much of the 20th century. In the 21st we may finally be being overwhelmed by it. Possibly without realising. How society resolves a potentially uncomfortable relationship with nothing is important. And intriguing. It’s possibly the most difficult problem to resolve, yet underpins many contemporary issues.

This article introduces 3 approaches to resolving nothing. They are an attempt to summarise various different articles I’ve written over the past year. Broadly:

  • Tangible Renaissance: Physical representations of nothing. Idols to communicate abstract values. Belief in certainty.
  • Virtual Illusion: Virtual consumerism. An economy base on nothing, happily sustained in the denial of the meaninglessness. Belief in who cares?
  • Post-Existential Skepticism: Understanding built from nothing. Presumption of illusion. Belief in uncertainty.

This text is poorly researched, incomplete, and, well, uncertain. But it might be an interesting summary of the extent of my current confusion. This is written from a Western, especially British-American perspective. Keep these quotes in mind: Read More

Turning the Health World Upside Down

There’s a growing acceptance of the links between health, wealth and wider society. Not just the impact of wealth inequalities on measures like life expectancy. But the importance of fixing the underlying social causes of medical problems, rather than just administering the medicine and wondering why the patient doesn’t get better.

It’s convenient to frame this as a Third World problem. And while it is, it’s also a problem within and between developed countries. For example, people from one area of Glasgow (in Scotland) live a decade longer than people residing in another area of the same city, in spite of (theoretically) having access to precisely the same medical expertise.

A most basic analysis of Great Britain (and much of the developed world) reveals an organizational chasm, which most people are not prepared to cross: For example, medical services and social care provision are completely different activities – separate funding, differing structures, responsibilities, professional bodies. Even though individual “patients” shift seamlessly between them. It’s an organisational situation made worse by the difficulty both groups seem to have integrating with anything – in my experience (largely failing to integrate public transport into health and social services), a combination of:

  • The intrinsic (internal) complexity of the service itself, which leaves little mental capacity for also dealing with “external” factors.
  • The tendency to be staffed by those with people-orientated skills, who are often less able to think strategically or in abstract.
  • The dominance of the government, with a natural tendency towards bureaucracy and politicized (irrational) decision making.

Complexity is the biggest problem, because it keeps getting worse: More (medical) conditions and treatments to know about, higher public expectations, greater interdependence between different cultures and areas of the world. Inability to manage growing complexity ultimately threatens modern civilization – it will probably be one of the defining problems of the current age. So adding even further complexity in the form of understanding about “fringe issues” is far from straightforward.

Beyond these practicalities lurk difficult moral debates – literally, buying life. Public policy doesn’t come much harder than this.

Into this arena steps Nigel Crisp. Former holder of various senior positions within health administration, now a member of the UK‘s House of Lords. Lord Crisp’s ideas try to “kill 2 birds with one stone”: For the developed world to adopt some of the simple, but more holistic approaches to health/society found in the less developed world, rather than merely exporting the less-than-perfect approach developed in countries like Britain.

To understand Crisp’s argument requires several sacred cows to be scarified: That institutions like the National Health Service (which in Britain is increasingly synonymous with nationhood, and so beyond criticism) are not perfect. That places like Africa aren’t solely populated by people that “need aid” (the unfortunate, but popular image that emerged from the famines of the 1980s). That the highest level of training and attainment isn’t necessarily the optimum solution (counter to most capitalist cultures). If you’ve managed to get that far, the political and organisational changes implied are still genuinely revolutionary: To paraphrase one commenter, “government simply doesn’t turn itself upside down”.

While it is very easy to decry Nigel Crisp’s approach as idealistic, even naively impractical, he is addressing a serious contemporary problem. And his broad thinking exposes a lot of unpleasant truths. This article is based on a lecture Crisp gave to a (mostly) medical audience at the University of Edinburgh. And the response of his audience. The lecture was based on his book, Turning the World Upside Down: the search for global health in the 21st Century (which I have not read). Read More

Alex van Someren’s Lucky Acorns

Alex van Someren. Alex van Someren is one of those rare people, without whom our modern world would probably be a little bit different. From writing the first book about programming ARM architecture, the computer processor which now sits at the core of almost every mobile phone on the planet. To providing the technology that made Secure Socket Layer (SSL) more commercially viable, and helped enable the ecommerce internet revolution of the late 1990s.

Yet his story is fascinating because it is a definitive study in luck: Not just pure chance. But the type of luck that comes from a combination of unusual personal interests, social circumstance, and the active pursuit of something different.

It’s a reality that few “successful” entrepreneurial people acknowledge, because it’s an uncomfortable reality: It doesn’t fit neatly into a 5-point plan for instant fame and fortune [also see box below]. And it leaves a nagging doubt that the outcome could easily have been unsuccessful. And while I suspect that Alex isn’t comfortable with pure chance, he provides ample examples of how other elements of luck can be biased. How the odds can be improved. The dice loaded more favourably.

Those examples make Alex van Someren worth understanding. This article is based on a talk he gave to the Edinburgh Informatics Forum. Read More

A Strange Game

Deathwing. So it happened again. The player client software for the latest World of Warcraft expansion, Cataclysm, leaked into the public arena long before it was intended to become public. Again, because this also happened with the previous 2 expansions. A third leak is beginning to look careless.’s (unofficial) explanation of this “failure of secrecy” ironically fails to explain most of reasons behind the Cataclysm leak. Perhaps because the politics are rather too Machiavellian?

This article discusses the relationship between the game developer and its “fansites”. It uses the Cataclysm leaks to try and explain the underlying politics. The article questions why Non-Disclosure Agreements continue to be used, when they are worse than useless. Finally, it ponders the risks of such apparently one-sided relationships.

I’ve tried to present a fair and balanced analysis, which raises some important issues that aren’t getting discussed, and should be. Obviously, I can’t know everything. Read More

Poor Gina

Comments on my original WeeWorld article continues to provide a fascinating insight into tweeny online society. Not just that so many people think I can help them, when I cannot. But that users are now as likely to be concerned about “stolen” user accounts, as they are about the social injustices of paying for points:

“Hi my name is Gina… I’m nine years old… I brought a prepaid card then some one hacked me for no reason… The username is *****… I used a fake e-mail and I don’t know how to get it back =[ Can you help me? PLEASE!”

I removed the 200 redundant characters Gina had added to the final word, that conveyed the true extent of her desperation. Literate, for such an apparently young US citizen, she also reveals some child-like confusion in causality and logic. Not that most adults could solve her problem: A “recovered” password can only be sent to the email address associated with the account – yet to receive the message, the email address cannot be fake. Further help is locked away on forums which can only be read by users who are already signed in. Signed in, using the password they can’t recover…

For a 21st century child, this is much closer to a science-fiction nightmare than adults might think: Inadvertently being locked out of a part of society by the flaws of an infallible machine. A part of society, because this stuff genuinely matters – often as much as traditional “playground” relationships. Substantial time (and often Dollar money) is invested in a user’s account. Huge networks of friends are built. The ability to start again, or start again somewhere else, is poor consolation indeed.

We can argue that having one’s virtual avatar hacked into is a “rite of passage” into the digital economy. A necessarily painful lesson that, long-term, will make adult activities such as online banking much safer. After all, this is only a childhood game, isn’t it?

Yet Gina’s short plea contains a lot of unpleasant truths, that adult society seems reluctant to address.

This article explores how the law, as experienced by the generation practically born online, differs from law as previous generations have learned it. Worlds where everyone is at least 13 years old, even if they aren’t. Where wrongs are not righted, because they’re not in the contract. And copyright legitimises a new, almost feudal social structure. A selective, but slightly unnerving, insight into a generation that may grow up to believe that law is for something else, because it so obviously isn’t for them. Read More

Difference and the Same

‘Blogosphere luminary, Larísa, thinks I’m smart. In capitals, because the word itself evidently lacks sufficient emphasis. Her implication, that this is a good thing.

Yet it’s driving me mad.

This article tries to explain why. It defines aspects of intelligence as difference from average, and then quantifies this as degrees of shared reality. The article provides a model where genius and stupidity are almost identical, where the closer someone is to the join, the closer they come to insanity – the “reality of one”.

It explains why wider human society continues to believe extremes of intelligence can be a positive attribute, in spite of the social disconnection associated with this. The article shows how perception-based, consumerist social structures have built reward structures upon this delusion. The nature of illusion is then considered, with particular reference to aesthetics, and the role of empathy in maintaining illusion among humans.

The article lastly introduces the concept of social gravity – the tendency of humans to the same – and then challenges the idea that everyone should be dragged back towards that single point of gravity: Rather, by maintaining multiple illusions, a social structure emerges where multiple extremes of difference can be maintained, while still averaging to the same.

Like some of my more abstract writing, this isn’t terribly well researched. Equally, the topic so broad, it isn’t practical to consider every counter-argument or divergence of thought within the text, and still maintain some form of readability. It may be helpful to first read Michael Gazzaniga’s Science of Mind Constraining Matter, which provides the rationale for some of the statements made in this article. Read More

Michael Gazzaniga on the Science of Mind Constraining Matter

Michael Gazzaniga. Can neuroscience explain it? You know – consciousness, being, the number 42. And if everything you thought you were transpired to be nothing more than an easily deceived heap of neurons, would that trouble “you”?

During October 2009, Michael Gazzaniga gave a fascinating series of Gifford lectures exploring how our brains process the information that gives us our sense of “I”. Gazzaniga drew extensively from neuropsychological studies of people with “split brains” (explained later) to develop the notion of a single “interpreter” within the brain – a part of the brain that analyses all the data available for meaning.

Michael Gazzaniga then attempted to rationalise the interpreter, concluding that our focus should be on the interactions of people, not the brain itself. This logic was then expanded to wider society – social structure, interaction, and law. Those later thoughts raised many more questions than were answered.

This article attempts to summarise the key themes in a non-technical manner, with a few naive attempts to interrogate the theories developed. This is my interpretation of 6 hours of lectures. Interpretation, because I tend to recreate Gazzaniga’s conclusions by re-analysing the information presented. With a complex topic such as this, it is likely that some of my interpretations will differ from his. Sections titled “Interlude” are entirely my analysis. Read More


As I write, the United Kingdom is in the midst of a national election campaign. A month during which politicians vie to confuse the electorate with big numbers. Politics is suddenly ravaged by intangibility, because the national economy is unable to sustain the usual tangible proxies for a better life – “more schools and hospitals” – and because the tangible results of fixing that economy tend to be unattractive – “less schools and hospitals”. So the best political strategy is not explaining the consequence of choices in a language ordinary people can understand.

Do you like the sound of £100 million ($150 million)? Can I tempt you with £160 billion? Expressing these figures per person in the population can be useful. The first figure is one bar of luxury chocolate for everyone. Doesn’t sound so big now, does it? The second figure is like everyone having a £2,500 bank overdraft (loan). Strange that, because indirectly, we do.

Unfortunately, applying the economics of household groceries to major items of government expenditure introduces certainty. The idea that one can visit a store where luxury chocolate bars are sold for precisely £1.70. Yet many large elements of government expenditure are akin to ordering a chocolate bar years before it can be eaten, for a price that transpires to be somewhere between £1 and £5.

Larger businesses will be familiar with this concept. It’s called risk. Such businesses are often far more interested in what “it might cost” (£5) than what “it will cost” (£1.70), because what it might cost might lead the business to bankruptcy.

The national economy is chaotic in its complexity, but overall, things should average out. So long as all the assumptions are broadly reasonable: Ultimately some will earn/cost more, some less. Short-term in-balance can be solved by (basically) printing more money, and then down-grading future assumptions until everything is back in balance.

However, this breeds a form of arrogance. A sense that government doesn’t need to consider the possibilities. That we can deliver a radical new policy – that has never been done before – and, in spite of it never having been done before, we know precisely how much it is going to cost. Just like a bar of chocolate.

Unfortunately, assumptions tend towards optimism. On average, projected costs are less than actual costs. This isn’t just a problem for accountants. It means that decisions are taken which do not reflect reality. Potentially leading to a Disneyland scenario, where everything is affordable until after the decision is taken, when suddenly everything has become too expensive. It ultimately challenges the validity of decisions, and in doing so, the moral authority of those that take them.

This article uses the Edinburgh Tram project to demonstrate the inherent uncertainty of large government infrastructure projects. It discusses the role of optimism in planning, and the methods used to reconcile planned optimism with subsequent reality. The article describes how the involvement of the private sector in public projects has evolved over the last 20 years, and the highlights the different time-scales applied to private investment and public choices. It concludes that optimism is not only unavoidable, but necessary. Rather, the true problem lies in tendency of people to demand certainty from the public sector, while accepting uncertainty in the private sector. Read More

Railways for Prosperity

Recreating the Island of Sodor in Kidderminster. In the dying years of Margaret Thatcher’s premiership, the United Kingdom government launched a policy document called “Roads for Prosperity”. £23 billion ($35 billion) would fund a network of highway improvements. Schemes that eased capacity constraints on the strategic (primary routes) road network. It was a response to rising car use, and the belief that not providing sufficient highway capacity would damage the UK economy – national prosperity.

It didn’t happen. Neither the threat to prosperity, nor the policy:

  • Environmentalists rallied against the few early projects (famously turning the Newbury Bypass and Twyford Down into civil battlegrounds) – road-building became politically negative, rather than positive.
  • There was never really enough money in national budget to fund the policy – increasingly obvious as the UK economy dipped into the recession of the early 1990s.
  • Even with the policy, roads would still be built slower that road traffic was growing – it was not possible to “build your way out” of the problem. It’s worse than it first seems, because new roads generate additional traffic growth, requiring more road capacity, generating more traffic…

The legacy was apparent in Tony Blair’s first Labour administration (or more accurately, John Prescott’s, the minister who led the transport and environmental agendas in the late 1990s): Much greater emphasis on sustainability, local projects, and use of forgotten modes, like buses and shoes.

Now, step forward 20 years to 2010.

The Secretary of State for railways and other transport, Lord Adonis, announces plans for a new high-speed rail line between London and Birmingham. At least £15 billion ($23 billion) for the first phase, rising to £30 billion with extensions further north. (Read those figures with caution – the costs of the previous West Coast Mainline upgrade project increased so much that nobody could remember how low the initial estimate was.) Inflation means that the cost of this latest rail project is only about half the (real terms) cost of Roads for Prosperity. But Roads for Prosperity proposed thousands of miles of highway, across many different locations, compared to a few hundred miles of railway track between a few large cities. And “Railways for Prosperity”, as I’ve corrupted the latest proposal, doesn’t have the pretence of strategy.

Politically it’s work of genius – the benefits flow to the political class (who tend to use trains), especially those living in increasingly marginal electoral territories in the West Midlands and North-West of England. Meanwhile, the Peoples’ Republic of Great Missenden (and soon likely every other other community near the route) is up in arms because the totalitarian regime they likely never voted for, has decided to build a railway – without the local station necessary for them to commute to London. I exaggerate, but only slightly.

Forget the “high-speed” aspect of the title. Operationally, the need is to increase capacity (see the box below). Make space for more trains on one of the busiest railway lines in Britain. More capacity creates more redundancy in the system, which makes it easier to recover from operational problems, and so makes trains more reliable. From bitter personal experience as a passenger, I suspect reliability is worth more than speed here. Of course, “better reliability” sounds a lot vaguer than “30 minutes faster”.

Read beyond the concrete, and the talk is all about “economic growth”, and “jobs”, and.

It’s at times like this that I want to pick up a shotgun and blow my brains out. 20 years later we’re back where we started. And nobody seems to have noticed.

This article uses historic examples to question the strength of the relationship between transport and the economy. It highlights the political biases towards railways, and their funding. The article explains why grand transport projects remain popular, when their overall impact on problems is often minimal. Rough analysis is presented that demonstrates the futility of building new railways – the 21st century reality, that we simply cannot afford to continue enlarging our transport networks in response to increased passenger demand. Finally, a stark comparison is made between communications and “transport” policy, which questions the validity of spending 15 times more on a new railway, than on a core element of “digital” inclusion. Along the way, the article clarifies a few popular misconceptions, from the influence of Unionism, to the impact of “integration”. Read More

Animal Farm

Pandaren Monk We finally have some reliable figures for the commercial value of “minipet” micro-transactions in the game, World of Warcraft. Specifically, the sales of just 1 item: In November and December 2009, at least $2.2 million worth of Pandaren Monk pets were sold. 220,000 at $10 each. We know this because “50% of the purchasing price” was donated to charity, and “more than $1.1 million” was donated (via

Over 220,000 sales to a market of about 4-5 million potential customers (only active WoW players can use the minipet, and the pet does not appear to have been sold in China or Taiwan). Roughly 5% of potential customers spent $10 on an ostensibly useless vanity item: A small pet that follows you around, looking cute.

Like most virtual goods, the cost of making and selling this pet is marginal: Primarily some additional art and marketing time, all built on the back of existing systems (store, staff, world). The first 2 months of Pandaren Monk sales will have made contributions to Blizzard’s profits of about $1 million. That’s only around 1% of the business’s turnover in that 2-month period. But that 1% is “free money”. Blizzard (-Activision) would be doing a dis-service to its investors if it did anything other than continue to milk this virtual cash cow.

Apply a healthy bit of European cynicism, and it is easy to conclude a scam. Tobold‘s:

“Send me $10, and I promise to send $5 of it to charity.”

Of course, Europeans fundamentally don’t understand US philanthropic culture: The idea that it’s fine to exploit your fellow human and make outrageous amounts of money, so long as you give some of it away in the end. Some philanthropy is able to take a somewhat rational, balanced view of what is good for the world. But there is a tendency to support visually appealing issues, such as charities servicing the needs of children.

The purpose of this article is not to argue that a European, government-centric re-distribution of wealth is preferable to an approach lead by personal responsibility. (I’m not sure it is.) The problem emerging here is more fundamental: That virtual goods are replacing trade-able value with non-trade-able value. Non-trade-able value that, by definition, can not offset inequality in (game) society. Donating part of the price of sales to charity is pure irony. In true Orwellian style, we’re sleep-walking into a potentially broken social structure with the best of intentions.

This article started as a box during my Adventures in the Invisible Tent, but has been expanded here in much greater detail. This article describes what a minipet is, highlights the role of money to balance inequality in society, and explains the problem with virtual goods. Read More

Nation of Adoration

World of Warcraft’s seasonal holiday events temporarily reduce player interest in fishing. It’s always been the case, but the decline in fishing seems to be becoming more extreme over time:

Decline in Fishing Activity due to Holiday Events

The graph’s y-axis is the percentage decline in page views at El’s Extreme Anglin’ from the 7 days before each event, to the first 7 days of the event. Pageviews are a good proxy for overall angler interest. El generates hundreds of thousands of page views each week, so even small changes are significant. The x-axis orders events by date, from January 2008. The axis isn’t scaled correctly to show time, but holidays are fairly evenly distributed throughout the year. Events are shown by green dots, with a shortened date (month and year) and the name of the event.

The data is expressed as a percentage of the previous week, because while interest in fishing “waxes and wains” from year-to-year, changes week-to-week are normally minor.

All the events included last at least 7 days. Where one holiday runs concurrently with another event (for example, the “Lunar Festival” and “Love is in the Air” often clash), only the first event in the sequence is included. Interest in fishing also changes dramatically in the month new content is added, so events that clash with major fishing patches have been excluded (Noblegarden 2008 with patch 2.4, Hallow’s End 2008 with patch 3.0.2, and Noblegarden/Children’s Week 2009 with patch 3.1). Winter Veil is also excluded: The period leading to Christmas is particularly unusual – first students stop studying and have a lot of time to play, and then many players stop playing to spend time with family. This causes large changes in activity from week-to-week, which makes it hard to isolate Winter Veil in the data.

Only 12 separate sets of data can be compared. There is one out-lier – Midsummer 2008 – perhaps the early stages of Wrath of the Lich King testing may have caused a small traffic spike in the week before? The pattern shown on the graph is not certain. But I’m growing confident that events are increasingly impacting on fishing activity.

But why? Read More

Adventures in the Invisible Tent

Here’s a tent.

Invisible Tent

It’s invisible. But it is. There. Walk forward into the space it occupies, you find yourself within the tent.

Inside Invisible Tent

The tent only exists when one is within it. When outside, we see the world without the tent.

This article explores the implication of this uncanny art form on how we build and use virtual environments. It first explains why this invisible tent is considered to be a software bug. The article explores how our ability to accept the uncanny varies from person to person. It then suggests that the spatial, built, environment is far less important than the social structures that exist within them. This topic contains a lot of images. Read More

Elevator Adverts

Elevator adverts are a way of displaying advertisements on web pages. Not for elevators in buildings. The name refers to the way the advert moves up and down the margin of the page, as the reader scrolls up and down. A standard “skyscrapper” advertising block is always visible, right next to where the user is reading.

Advertising networks are keen for adverts to be displayed “above the fold” – in the area of the screen first visible when the page loads. However, if the page is content-rich, the best locations are not at the top of the page: In the past, I have run advertising using 2 skyscrappers, one on top of the other. As the reader scrolls down the page, the second advert eventually becomes visible. The best return (from affiliate advertising) was from the bottom advert, not the top. The reason is simple: Reading down the page, the lower advert tends to be next to the important text being read. In contrast, the upper advert tends to sit next to the list of page contents, so is often skipped over.

Instead of stacking adverts, why not just move the advert down the page as the reader scrolls?

The webpage needs an “elevator shaft” down the left margin. For example, apply the CSS “margin-left: 175px” to the division (“div” block) containing the page’s content, to create the elevator shaft. More complex designs may require more work. It is important that the elevator shaft runs close to edge of the text, to continually catch the eye of the reader.

Simply applying a “position: fixed” to style the division containing the advert, would always show the advert in the top-left corner, hanging down the elevator shaft. Unfortunately, the top part of the page normally contains a title block, so the elevator shaft should not travel the full height of the page. Older browsers (notably Internet Explorer 6) do not support “position: fixed”, but we still need to make sure the advert “fails gracefully”, by displaying in a sensible position.

My solution’s code is below. Read More

Ian McCaig’s History of Ian McCaig,‘s Chief Executive Officer, told the history of this online travel and lifestyle retailer to the Edinburgh Entrepreneurship Club.

From a stereotypical “dot com” baby in 1998, to the rapidly maturing teenager of 2010. Ian charted the way in which the business’s strategy, structure and ownership had evolved as it matured from something with the turnover of a small local pub, to a multi-billion enterprise. Covering the problems of merging acquired companies, the need to scale costs, and the change from a public (stock market) ownership to private equity.
