Paris dawn

Dawn in Paris from the 29th floor of Hôtel Concorde La Fayette, looking north-east towards Sacre Cœur.  End of a few days as external expert for the INRIA Evaluation Seminar on “Interaction and Visualisation”.

I was also in Paris last September and changed my view of the city (hitherto rather poor).  I started a post about that then “Paris and the redemption of the French restaurant“, but never uploaded it at the time; however, I have now done so (post dated to Sept 2009).  Also on Flickr are more photos of dawn over Sacre Cœur and also I am uploading my photos from the previous Paris trip last Sept.

UK internet far from ubiquitous

On the last page of the Guardian on Saturday (13th Oct) in a sort of ‘interesting numbers’ section, they say that:

“30% of the UK population have no internet access at home”

I couldn’t find the exact source of this, however, another  guardian article “UK internet audience rises by 1.9 million over last year” dated Wednesday 30 June 2010 has a similar figure.  This says that Internet use  has grown to 38.8 million. The National Statistics office say the overall UK population is 61,792,000 with 1/5 under 16, so call that 2 in 16 under 10 or around 8 million. That gives an overall population of a little under 54 million over 10 years old, that is still only 70% actually using the web at all.

My guess is that some of the people with internet at home do not use it, and some of the ones without home connections use it using other means (mobile, use at school, cyber cafe’s), but by both measures we are hardly a society where the web is as ubiquitous as one might have imagined.

cracks in the ceiling, windows on childhood

This bedroom.  Where she knew the pattern of cracks in the ceiling better than any other fact of her life.
Shipping News, p.54

Reading this, I realised I also remember the patterns on the ceiling above Mum and Dad’s bed in the big bedroom in Bangor Street, where my sister and I also slept in bunk beds.  As I lay, falling asleep with monkey held close, the pattern above seemed like the face and shoulders of some giant that had slept in the attic and left his impression in the plaster like the smaller dent in the sheets when I got up in the morning.

I had forgotten it, but I can see it now, patterns upon light green woodchip ceiling paper, as clear as the sky and grass before me where I am sitting now, and mornings with tea from the Goblin Teasmade and Dad bringing up marmalade-laden toast cut in triangles before, workman-fashion, he sipped hot tea from the saucer.

wisdom of the crowds goes to court

Expert witnesses often testify in court cases whether on DNA evidence, IT security or blood splatter patterns.  However, in the days of Web 2.0 who is the ‘expert’ witness?  Would then true Web 2.0 court submit evidence to public comments, maybe, like the Viking Thing or Wild West lynch mob, a vote of the masses using Facebook ‘Like’ could determine guilt or innocence.

However, it will be a conventional judge, not the justice of social networks, who will adjudicate if the hoteliers threatening to sue TripAdvisor1 do indeed bring the case to court. When TripAdvisor seeks to defend its case, they will not rely on crowd-sourced legal opinions, but lawyers whose advice is trusted because they are trained, examined and experienced and who are held responsible for their advice.  What is at stake is precisely the fact that TripAdvisor’s own site has none of these characteristics.

This may well, like the Shetland newspaper case in the 1990s2, become a critical precedent for many crowd-sourced sites and so is something we should all be watching.

Unlike Wikipedia or legal advice itself, ‘expertise’ is not the key issue in the case of TripAdvisior: every hotel guest is in a way the best expert as to their own experience.  However, how is the reader to know that the reviews posted are really by disgruntled guests rather than business rivals?  In science we are expected to declare sources of research funding, so that the reader can make judgements on the reliability of evidence funded by the tobacco or oil industry or indeed the burgeoning renewables sector.  Those who flout these conventions and rules may expect their papers to be withdrawn and their careers to flounder.  Similarly if I make a defamatory public statement about friend, colleague or public figure, then not only can the reliability of my words be determined by my own reputation for trustworthiness, but if my words turn out to be knowingly or culpably false and damaging then I can be sued for libel.   In the case of TripAdvisor there are none of the checks and balances of science or the law and yet the impact on individual hoteliers can make or break their business.    Who is responsible for damage caused by any untrue or malicious reviews posted on the site: the anonymous ‘crowd’ or TripAdvisor?

Of course users of review sites are not stupid, they know (or do they) that anonymous reviews should be taken with a pinch of salt.  My guess is that a crucial aspect of the case may be the extent to which TripAdvisor itself appears to lend credence to the reviews it publishes.  Indeed every page of TripAdvisior is headed with their strap line “World’s most trusted travel advice™”.

At the top of the home page there is also the phrase “Find Hotels Travelers Trust” and further down, “Whether you prefer worldwide hotel chains or cozy boutique hotels, you’ll find real hotel reviews you can trust at TripAdvisor“.  The former arguably puts the issue of trust back to the reviewers, but the latter is definitely TripAdvisor asserting to the trustworthiness of the reviews.

I think if I were in TripAdvisor I would be worried!

Issues of trust and reliability, provenance and responsibility are also going to be an important strand of the work I’ll be part of myself  at Talis: how do we assess the authority of crowd-sourced material, how do we convey to users the level of reliability of the information they view, especially if it is ‘mashed’ from different sources, how do we track the provenance of information in order to be able to do this?   Talis is interested because as a major provider and facilitator of open data, the reliability of the information it and its clients provide is a crucial part of that information — unreliable information is not information!

However, these issues are critical for everyone involved in the new web; if those of us engaged in research and practice in IT do not address these key problems then the courts will.

  2. The case around 1996/1997 involved the Shetland Times obtaining a copyright against ‘deep linking’ by the rival Shetland News, that is links directly to news stories bypassing the Shetland News home page.  This was widely reported at the time and became an important case in Internet law: see, for example, Nov 1996 BBC News story or netlitigation.com article.  The out of court settlement allowed the deep linking so long as the link was clearly acknowledged.  However, while the settlement was sensible, the uncertainty left by the case pervaded the industry for years, leading to some sites abandoning link pages, or only linking after obtaining explicit permissions, thus stifling the link-economy of the web.

beyond books and blood

With most others, I was sickened by Pastor Terry Jones’ threat to burn copies of the Qur’an; it is directly counter to the Christian message and basic human decency.  Happily, this now seems to have been abandoned. However, while this was provocative and insensitive and may be used as an excuse for violence across the world, there seems to be a subtle and worrying shift as many have suggested that he will be responsible for any violence or even deaths.

However vile Jones’ threat was, the responsibility for violence lies with the perpetrators.

We seem to have lost the plot somehow when the burning of a book claims more news time and more  condemnation than those persecuting, maiming and killing people.

I am sure both true Muslims and Christians know that God’s dignity is not diminished one iota by the desecration of any book or building (including Ground Zero), even though our own feelings, dignity or pride may suffer. And I am certain they also know that God’s love extends to victims whatever their beliefs.

Let’s set our attention on the important things and leave those like Pastor Jones to the obscurity they deserve.

Across Ireland to Limerick: Stepping Out of Time

Early last week I had  a few days external examining the iMedia course at Limerick.  A wonderful course I was impressed again at the Dawn 2010 show pieces produced by the students who come predominantly from arts or design backgrounds and many of whom have never touched code or soldering iron before starting the course.

As it was Bank Holiday weekend, flying would have meant spending 24 hours in an airport between flights and airport hotels in each direction, or alternatively driving south to an airport.  It seemed more sensible and more fun to drive south through Ireland itself, and in the process satisfy a little my itinerant spirit.

I didn’t manage to write as I went along, but have retrospectively made a number of post-dated photo-blogs:

Roads of the Sea — Tiree to Larne

Into the West — Larne to Westport

Serendipity and Song — Westport to Doolin

Last Day — Doolin to Limerick

Full set of photos at my Limerick-Aug-2010 Flickr photo set

Said goodbye to our little dog Tansy over weekend.  I am not one of nature’s dog lovers, but it is amazing how one gets attached to a small bundle of fur, I just wish I had been at home in Tiree with Fiona at the time.  At nearly 17 she was very old in doggy years, seemed to be happy to the end and certainly gave a lot of happiness to others, which is a pretty good epitaph for anyone.

Last Day — Doolin to Limerick

From Doolin’s harbour side you can see the ferries that ply back and forth to the Aran Islands.  The rock is limestone, like the Burren, and the land beneath cut through with caves including the world’s largest stalactite and the submerged ‘Green Holes’, only discovered in the 1980s.

While the Aran Islands stretch across the sea to the North West, to the South West rise the Cliffs of Moher, 200 metres from the sea, shortlisted alongside Kilimanjaro, the Great Barrier Reef and the Grand Canyon to be one of the new seven wonders of nature.  There is no beach, no sand or shingle, just sea and shear rock, but surfers travel there to ride the 35 foot wave at its feet.

The Moher visitor centre is dug and buried into the hillside with curved windows cut through the turf; Hobbit Town meets HiTech,  The paved, stepped, and wheelchair-access routed area with its viewing points and wall of wave-patterned Burran limestone slabs, ends at widely ignored signs threatening danger to life and limb if one proceeds.  You can see why the signs are there; it is not so much the lack of fence or wall between the cliff top path and precipitous edge, but the rock itself.  The limestone of the Burran, Doolin coast and Aran Isles has ended and this is younger, softer alluvial rock, at the cliff top often little more than flakes of shale in hardened mud.  The tourists peeking over the edge may be secure in footing, but the soft cliff edge itself might shrug them off to fly for a moment amongst the nesting gulls before hitting the water 600 feet below.

And out on the grass beside the forbidden cliff path, an Italian couple set up a video camera looking out towards the rocky headland, and sit in front of it to exchange rings.

Back at the visitor centre a sculptor was hard at work with chisel, angle grinder and chain saw, capturing the spirit of Maher from surfer to sea birds.  Shane Gilmore‘s sculptures are found across Western Ireland, and he was commissioned to make this one in situ during the Clare Heritage Week.  At Shane’s feet lay a collection of reference books; he explained that if he got some detail wrong, gave a bird the head of a gull and the body of a gannet, someone would be sure to notice.

It is only a short way from Doolin and Maher, and slightly longer of you cut back north to travel across the Burren, but worth it, for its near lunar yet surprisingly fertile landscape.   Few roads cut across the limestone countryside but far beneath the ground are subterranean rivers and networks of caves left from past water courses, treacherous as they too can flood rapidly when rain falls and drains through sinkholes and caverns.

At a distance the Burren landscape appears barren, but between the clints, giant paving slabs of grey stone, the cracks, or grykes, are rich with wild flowers and lush grasses that supported communities from Neolithic times, who in turn left their traces in fire circles and ring forts.  And near every parking place, each clint is topped with a tiny cairn or sculpture as visitors today still want to leave some trace of their being here, or maybe token of their hoped-for return.

Serendipity and Song — Westport to Doolin

Westport nestles on the far shore of one of Ireland’s great peninsulas, jutting into the Atlantic, with the Mountains of Connemara to the south and the wild coasts of Achill to the north.   Some years ago we camped on Achill Island in late September.  Most Irish campsites close after the first week of September but we found one campsite still open although only one other campervan stopped by in the few days we spent there.  The site had several permanent mobile homes, and despite the 8 foot banks of grass-topped sand that protected the site each was held to the ground with structures of foot-wide girders to hold them down against the force of the Atlantic winds.  We parked close between some of these and as the campervan shook in the night reminded ourselves that these were just mild September breezes, not the wild storms of the winter.

This time I had to set my face south cutting across Connemara to Doolin for the night.  I took the coast road between Croagh Patrick and the sea, passing the car parks and coaches at its foot where the pilgrimage route begins.  Although I’ll forgo the climb on hands and knees of the true pilgrim it would be good to climb it some day for the view and the sense of those who have visited this holy spot for a thousand years.

I do not have a SatNav and somehow at Louisburgh I took the wrong road.  As the road narrowed to single track and then grass began to grow down the centre, I realised my mistake, but assumed it would eventually join up with the main road.  In fact I was driving down a 15 mile cul-de-sac.  Often when I have lost my way in a strange city, I have vowed I would get a SatNav, but now I am glad I have not.  Global communications and perpetual internet offer instant information and allow us to plan every journey with printed Google maps and reviews of each tiny coffee house.  But it would be a Faustian bargain if it were to rob us of the joy of just one unexpected and unplanned mistaken road to paradise.

On the far south west of County Mayo, there is a tiny nick in the coast on the map, and the indistinct line leading to it is this road, skirting the coast, looking out to islands and ocean, and ending at that nick, named like so many other simply White Strand.

Although my feet ever itch to wander, if there were a place to stop for a while and taste the ocean air, this would be it; but with many miles to go, I had just a few minutes to walk among the dunes and check where I was with three lads taking turns on a quad bike across the broad washed sand, before setting on my way again, back along the road I had come and again amazed at the way I had come and the fortune of following a ‘wrong’ path.

Through Connemara and many mountains calling to be climbed and lakes to be sailed; past Galway, the sound of tin whistle and fiddle almost audible even from the European funded ring road that bypasses the town’s old streets; along the coast of Northern Clare with the Burran on the left and sea on the right and on down, over the little bridge to Doolin and Fisher Street.

Fiona and I had camped in Doolin many years before, but we arrived late, the night was wild, and the ground in the campsite down by the harbour more like marsh than grass1.  So we stayed in the van, opened up the roof just far enough to poke out our heads, feel the wild wind whip our hair, and see the waves crash against the feet of the Cliffs of Moher.  So this was the first time I had visited the legendary O’Connors and experienced a session there.

Doolin is a Mecca for traditional music: around the bar several Japanese faces, a lady from South Carolina, and a couple of hitchhikers from Lille meandering their way around the Western Ireland, cooking pasta in a battered saucepan.   Perched on a bar stool, I chatted over dinner with a man who lives just 25 miles away, staying in his caravan overnight, ready for a day visit to Inis Mór, the largest of the Aran Islands the next day. He had briefly visited the islands 12 years before, but this time was planning to walk across Inis Mór to Dún Aonghasa, the huge Iron Age fort cut in half by the eroding cliff face. I was reminded of the parable “the wise man built his house upon rock”, but after over 2000 years even the limestone of the Aran Isles is no sure foundation against the buffeting of the North Atlantic waves, that can throw vast boulders up to the cliff tops from the sea 25 metres below.

At 9:30 the music group began to assemble, three men who clearly played together and others invited into the music making, an older man with no instrument who later sang, and others.  It is an inclusive music, with no pretension, Guinness lubricates the beating Bodhrán and pumping accordion, and the old hands play alongside the young.  One couple, maybe students visiting during the summer vacation, looked nervous but were welcomed in and a young boy, maybe 12 or 14 years old, sang and played tin whistle, gradually growing in confidence as the night wore on.
