Fairport Convention are one of those bands that have been around for what seems like forever and still keep truckin' on. I discovered them while I was in university and saw them at Convocation Hall in Toronto in the mid-70s. Last year, they celebrated, slightly belatedly, the 50th anniversary of their album, Full House, by performing it in full at the Cropredy Folk Festival. Fortunately for us, the performance was recorded and has been released as the album Full House For Sale.
It was a treat that had been stuck in the pipeline for three years, blocked by the persistence of that wretched COVID thingy, but, at around 9:30pm on the evening of Saturday 13th August, Fairport’s 1970 lineup of Simon Nicol, Dave Pegg, Dave Mattacks and Richard Thompson, plus Chris Leslie who was standing in (wonderfully, as it turned out…) for the otherwise-occupied Dave Swarbrick reconvened on the Cropredy stage, and it was “Game On.” And WHAT a performance they delivered.
And, happily, Fairport have had the good sense to preserve that magnificent performance – not in aspic – but the on digital optical information storage format that we know as a Compact Disc. And, thank heavens they did, because Full House For Sale is destined to become a treasured memory of a landmark Fairport performance. Already, I have a suspicion that this new album may well be Fairport’s best and most enduring “Live” album ever.
This is not the first time a live version of Full House has been released. The excellent album, House Full, recorded live at The Troubador in 1970, has most of the songs from Full House, and captures that version of the group at their best.
I've been nearsighted all my life so I tend to take it for granted. But I will agree that it's not a normal condition, in the sense that it's a departure from baseline health. And it is becoming more common, but until I read this article, I hadn't realized just how common.
The article focuses (sorry, couldn't resist) on Taiwan, where more than half of children were myopic, and the efforts of one doctor to determine the cause and find a way to prevent it. It turns out that it's possible to reduce the incidence of myopia in children by having them spend more time outdoors and this has been determined to work.
Myopia, or what we commonly call nearsightedness, happens when the eyeball gets too long—it deforms from soccer ball to American football—and then the eye focuses light not on the retina but slightly in front of it, making distant objects appear blurry. The longer the eyeball becomes, the worse vision gets. Ophthalmologists measure this distortion in diopters, which refer to the strength of the lens required to bring someone’s vision back to normal. Anything worse than minus 5 diopters is considered “high myopia”—somewhere between 20 and 25 percent of myopia diagnoses around the world are in this category. In China, up to 90 percent of teenagers and young adults are myopic. In the 1950s the figure was as low as 10 percent. A 2012 study in Seoul found that an astonishing 96.5 percent of 19-year-old men were nearsighted. Among high schoolers in Taiwan, it’s around 90 percent. In the US and Europe, myopia rates across all ages are well below 50 percent, but they’ve risen sharply in recent decades. It’s estimated that by 2050, half the world’s population will need glasses, contacts, or surgery to see across a room. High myopia is now the leading cause of blindness in Japan, China, and Taiwan.
If those trends continue, it’s likely that millions more people around the world will go blind much earlier in life than they—or the societies they live in—are prepared for. It’s a “ticking time bomb,” says Nicola Logan, an optometry professor at the UK’s Aston University. She wasn’t the only expert I talked to who used that phrase. Because so much of Taiwan’s population is already living life with myopia, the island nation has already glimpsed what could be coming for the rest of us. And in a rare confluence, the country may also be the best place to look for solutions.
If you've been reading this blog for a while, you'll know that I am pessimistic about the future of our technological civilization. (See my We're Toast topic for reasons).
There is a pattern to the collapse of civilizations, even successful ones, as described by Jared Diamond in his seminal book, Collapse: How Societies Choose to Fail or Succeed. In this article by Michael Klare, he looks at the state of our civilization in the light of Diamond's framework. We are not looking good.
The question today is: Will our own elites perform any better than the rulers of Chaco Canyon, the Mayan heartland, and Viking Greenland?
As Diamond argues, each of those civilizations arose in a period of relatively benign climate conditions, when temperatures were moderate and food and water supplies adequate. In each case, however, the climate shifted wrenchingly, bringing persistent drought or, in Greenland’s case, much colder temperatures. Although no contemporary written records remain to tell us how the ruling elites responded, the archaeological evidence suggests that they persisted in their traditional ways until disintegration became unavoidable.
These historical examples of social disintegration spurred lively discussion among my students when, as a professor at Hampshire College, I regularly assigned Collapse as a required text. Even then, a decade ago, many of them suggested that we were beginning to face severe climate challenges akin to those encountered by earlier societies — and that our contemporary civilization also risked collapse if we failed to take adequate measures to slow global warming and adapt to its inescapable consequences.
But in those discussions (which continued until I retired from teaching in 2018), our analyses seemed entirely theoretical: Yes, contemporary civilization might collapse, but if so, not any time soon. Five years later, it’s increasingly difficult to support such a relatively optimistic outlook. Not only does the collapse of modern industrial civilization appear ever more likely, but the process already seems underway.
I'm afraid that I have to agree with him.
If you think that getting COVID is no big deal, you may want to read this article from Eric Topol's Ground Truths newsletter. Based on his analysis of some recent studies, the news is not good.
Today there are 2 new papers published on the 2-year follow up of over 100,000 people with Covid and millions of uninfected controls. In this edition of Ground Truths, I’ll review the salient findings of the 2 studies, and highlight the uncertainties of our knowledge base for Long Covid, which has already compromised the lives of tens of millions of people. Unfortunately, what was seen at 6 months largely continues out to 2 years.
A couple of months ago, I bought an Amazon Fire HD 8 tablet to use as an ereader. I had intended to use it for occasional web browsing, mostly to read news sites, but I've found that Amazon's proprietary version of Android limits its use for me. So I'm using it mostly as a replacement for my Kindle Paperwhite. I do use the Paperwhite when reading outdoors because neither my phone or tablet are great for reading in bright sunlight.
There are four apps that I've used for reading.

Bruce Springsteen and the E Street Band are out on a tour that started in February and will bring them to Toronto in November. And I have tickets! So in celebration of that, here's a video of their stop in Amsterdam in May. The video is pieced together from various fan recordings and combined with official audio. Enjoy!
This post is a collection of links that support my increasingly strong feeling that the human race (or at least our technological civilization) is doomed. It is part of an ongoing series of posts.
It's time to post links to more news about COVID-19. No, the pandemic is not over, the virus keeps mutating in new and unpleasant ways, and cases are increasing after a lull. In my region, cases have tripled in about four weeks.
I'm starting with two posts from Eric Topol's Ground Truths newsletter.
The Arecibo Observatory is no more. It officially closed its doors on August 14. There were plans to turn it into a science education centre, but funding for that has not been approved.
Nature has an article about the last days of the observatory. It's a sad article though it does mention some plans that in the long-term may result in science being done there again.
The observatory’s main attraction — a 305-metre-wide dish that was responsible for, among other things, studying near-Earth asteroids, discovering exoplanets and observing gravitational waves — was destroyed in 2020 when some support cables snapped following years of delayed maintenance. In 2022, the US National Science Foundation (NSF), which runs the facility, announced it would not rebuild the dish, citing community recommendations to put the agency’s limited budget into other, newer astronomical facilities. Instead, the NSF said it would convert the observatory into the Arecibo Center for STEM Education and Research (ACSER).
Under this plan, the agency would award between US$1 million and $3 million per year to an institution to manage the centre on a day-to-day basis. Before the telescope's collapse, the NSF was contributing $7.5 million annually to Arecibo, and management of the site was led by the University of Central Florida in Orlando.
When calling for proposals to manage ACSER, the NSF projected that the centre might open this year. But Monya Ruffin, deputy director of the NSF’s Research on Learning in Formal and Informal Settings Division, now says that the agency hopes to “make an award in 2023”.
Now the world's largest radio telescope is a 500-metre dish in China. Other even larger telescopes, such as the Square Kilometer Arrary, are under construction.
I get a lot (probably too many) email newsletters, most of which are tech related. But a few are from authors, primarily science fiction authors. The ones I'm highlighting here are free, though you can contribute to the authors if you wish to get extra content.

Here in the Great White North, it's almost time for another long weekend; this one being known (in Ontario, at least) as Simcoe Day or just the Civic Holiday. I'm going to start a longer hiatus with that and take a week, or possibly more, off from blogging.
We've been busy trying to get my later mother-in-law's house ready for sale. We're almost there, but the next week will be busy. If I'm not over there helping, then I'm going to be busy here keeping this place going. And a week from Saturday we have Bell coming in to switch our internet and TV over from Rogers, which means we have to empty and move two filing cabinets because they're blocking access to where all the external connections come into the house.
So I'm taking some time off from Core Dump. If all goes well, I'll be back here sometime around August 14. In the meantime, here are some flowers.

The worst of the COVID-19 pandemic being behind us (At least I hope so!), it's possible to look back and have a good, hard look at Canada's response to the disease. The BMJ (British Medical Journal) has published an analysis that looks at the high and low points of the Canadian response. It's worth a read, especially if you're Canadian, though I'm sure it would be useful no matter what country you live in.
Here are some of the key points:
I still miss Google Reader. For a fwe years, it was my primary interface to the internet because it made it possible to quickly scan through a tremendous volume of news and web posts in much less time than it would take to visit individual sites.
I've always wondered why Google killed it off, and this article from the Verge explains why, or at least provides the gory details of what happened.
Google’s bad reputation for killing and abandoning products started with Reader and has only gotten worse over time. But the real tragedy of Reader was that it had all the signs of being something big, and Google just couldn’t see it. Desperate to play catch-up to Facebook and Twitter, the company shut down one of its most prescient projects; you can see in Reader shades of everything from Twitter to the newsletter boom to the rising social web. To executives, Google Reader may have seemed like a humble feed aggregator built on boring technology. But for users, it was a way of organizing the internet, for making sense of the web, for collecting all the things you care about no matter its location or type, and helping you make the most of it.
A decade later, the people who worked on Reader still look back fondly on the project. It was a small group that built the app not because it was a flashy product or a savvy career move — it was decidedly neither — but because they loved trying to find better ways to curate and share the web. They fought through corporate politics and endless red tape just to make the thing they wanted to use. They found a way to make the web better, and all they wanted to do was keep it alive.
RSS feed readers have not gone away, thank goodness, although with the fragmentation of the web into (sometimes paywalled) niches, the number of sites that support RSS or Atom feeds has decreased. I use Feedly, which works well on both my desktop PC and phone. There are others. Here are a couple of review articles from Wired and Zapier that are reasonably current. If you aren't using a feed reader, I strongly recommend checking out Feedly or one of the other tools mentioned in the articles. You will wonder how you ever got along without one.
