Comments revisited

I have just approved eight comments that were sitting in the moderation queue - some of them for over two months. Clearly I am not all that good with this whole comment moderation thing. The blog was only asking for moderation on comments on posts older than fourteen days, but with my current blogging activity rate, that has, at times, included everything, even the most recent entry here. I have decided to remove the comment moderation requirement, and just go with the captcha method of spam comment prevention for now. We'll see how it goes. That may well be enough.

If you've commented and been disappointed in not receiving a reply, I apologize. Thanks for coming by, and I hope you'll be back again to allow me to make ammends.

The ABCs of Curling - R

is for rock. I've touched on the rock in several previous entries, including 'A', where I discuss a rock's origins; 'I', in which I mention the rock's unique shape, and 'L', which treats the way a rock interacts with the ice when it is in motion. Finally, the rock gets to be the star of its very own entry.

A little bit of decorating

We recently repainted the living room/dining room area in our house. By recently, I mean, last summer. Since then we've been slowly picking away at this design element, and that accessory, and the other piece of furniture. The new couch arrived last week (and when I say arrived, I mean, we borrowed my father-in-law's van and went to Sears to pick it up ourselves). Prior to that, Pat had nabbed a large mirror for the wall above the couch from one of those discount home stores for some stupid stupid low price. I think it was regular fifty nine dollars, on sale for twenty nine dollars, on clearance for seventeen-fifty. Looks awesome, and no one notices the teeny little crack in the bottom corner. (Or, you know, if they do, I hit them over the head with a big stick, drag them down into the basement, and brick them up behind a wall.)

The one thing we had the hardest time with was deciding what to do with the long wall that runs the full length of both the living room and the dining room. Finally, we decided to create a photo mosaic of multiple smaller pictures, rather than try to find larger, affordable (key, that) prints to hang. I dusted off the CD full of pictures I took during our trip to Italy four years ago, and we made a run to IKEA to pick up a gaggle (herd? pride? clutch? flock? drove? brood?) of frames, in a variety of sizes.

Here is the result:



You can click on the picture to go to my Flickr photostream, where you can look at a larger version of this picture, and all of the photographs we used to fill the frames. You know, if you want.

Don't click this link!

Today I signed in to Facebook to find a message telling me that one of my "friends" had posted a link on my wall. It was a You Tube link with the title, "WOW Video!" I was about to click on it to see what video this "friend," Kathryn, was sending me. Before I could, though, my skeptical radar kicked in, and I hesitated. Why would Kathryn, who is the older sister of a guy I was sorta friends with, on and off, in public school, more than thirty years ago be sending me a link to a video with no note of explanation attached? I mean, I knew her, and all, but we "friended" each other on Facebook because of that "friend" suggest feature: she was a "friend" of a "friend" of someone who was a "friend" of one of my "friends"...or something like that. But since we "friended" each other, we haven't actually exchanged two words. (Hi Kathryn - there, that's two).

I have this little habit I have developed over several years of web surfing. Before I click any link, I hover my mouse over it first, and look at the bottom left corner of my browser to see if the actual URL is the same as the one presented to my mouse. In this case, it was - no flag there - or was there? Sure it was a web address that had the words, "youtube," in it, but YouTube addresses all start with youtube dot com slash something, something, something. In this link, the 'youtube' was later in the address, with a bunch of random numbers in front of it. But Facebook pages are wierd, they embed other links within them all the time. I clicked on the link.

I did it, I clicked the link. I was lucky. It took me to a page titled, "Facebook Video," with a little video window on the left, and a picture of my "friend" on the right, and a message that said, Kathryn wants you to see this video. But the little video screen was black, with a message in it that said, "you must upgrade to the latest version of Flash to see this video. Click here to upgrade." I...almost clicked there to upgrade. Two things saved me. First, I have a teenaged son who uses YouTube on a daily basis. I'd seen him using it yesterday. I mean, it's possible that my Flash player needed an upgrade from yesterday to today, but that skeptical radar was buzzing again. I did my little hover the mouse trick again, and noted that clicking the link in question would download a file called setup.exe - a perfectly reasonable thing for an upgrade link to point to. I almost clicked the link. I didn't click. I have this pathological fear of exe files.

I started adding up all the little warning signs in my head, and they added up to, "danger, Will Robinson!" I deleted the link from my wall, and headed over to Kathryn's profile page to ask her if she, indeed, had sent me the link intentionally. And I wasn't the first. There were seven comments before mine, all saying, "hey! Why'd you send me a virus?"

Chalk one up for skeptical radar.

The ABCs of Curling - Q

is for Queen of Hearts. In the 1990s the hearts of curlers everywhere were captured by an attractive, outgoing, and talented woman by the name of Sandra Schmirler. Over a six year period, from 93-98, Schmirler guided her team of Jan Betker, Joan McCusker, and Marcia Gudereit to three Canadian Championship titles, three World Championship titles, and an Olympic gold medal. They were perhaps the first women's team to dominate the sport in a significant way, and certainly one of the first women's teams to become strong ambassadors for the sport. To this day, they are considered to be among the best women's teams to ever play the game.

Sandra Schmirler succumbed to cancer in 2000, at the too-young age of 36. She left behind a loving husband and two young children. She is remembered as The Queen of (the Scott Tournament of) Hearts.

Beware the spinal trap

I'm joining a large group of skeptical activist bloggers around the world today in reposting an article written by Simon Singh in the UK about Chiropractic "medicine." Simon wrote a fully factual article about the complete lack of evidence supporting the efficacy of chiropractic in treating non-spine related conditions, like colic. (No, I'm not joking. Some chiropractors actually claim to be able to treat colic via chiropractic spinal adjustment. Frightening, isn't it?)

Mr. Singh, for his efforts, prompted the British Chiropractic Association to provide evidence for their claims-

-no, wait, that's not what they did-

-oh, yes, they sued him for libel. Once again, I am not joking.

British libel laws being what they are (guilty until proven innocent - I swear this is not a comedy piece, the burden lies upon Mr. Singh to prove his case, even though he is the defendant), no one would have blamed Mr. Singh for retreating in the face of a large group with deep pockets able to fund hot-shot lawyers. That is not what happened. Mr. Singh has appealed the initial judgement against him, and is taking his fight - at great personal cost and risk - to a higher court. In support, I, and hundreds of other bloggers have agreed to repost the article that started the entire kerfuffle. Note that minor changes have been made to the article on the advice of legal counsel in order to prevent the BCA from adding more defendants to their suit. Should you wish to read the unedited version of the article, you can do so, I am told, at Respectful Insolence.

Beware the Spinal Trap

Some practitioners claim it is a cure-all, but the research suggests chiropractic therapy has mixed results – and can even be lethal, says Simon Singh.

You might be surprised to know that the founder of chiropractic therapy, Daniel David Palmer, wrote that “99% of all diseases are caused by displaced vertebrae”. In the 1860s, Palmer began to develop his theory that the spine was involved in almost every illness because the spinal cord connects the brain to the rest of the body. Therefore any misalignment could cause a problem in distant parts of the body.

In fact, Palmer’s first chiropractic intervention supposedly cured a man who had been profoundly deaf for 17 years. His second treatment was equally strange, because he claimed that he treated a patient with heart trouble by correcting a displaced vertebra.

You might think that modern chiropractors restrict themselves to treating back problems, but in fact some still possess quite wacky ideas. The fundamentalists argue that they can cure anything, including helping treat children with colic, sleeping and feeding problems, frequent ear infections, asthma and prolonged crying – even though there is not a jot of evidence.

I can confidently label these assertions as utter nonsense because I have co-authored a book about alternative medicine with the world’s first professor of complementary medicine, Edzard Ernst. He learned chiropractic techniques himself and used them as a doctor. This is when he began to see the need for some critical evaluation. Among other projects, he examined the evidence from 70 trials exploring the benefits of chiropractic therapy in conditions unrelated to the back. He found no evidence to suggest that chiropractors could treat any such conditions.

But what about chiropractic in the context of treating back problems? Manipulating the spine can cure some problems, but results are mixed. To be fair, conventional approaches, such as physiotherapy, also struggle to treat back problems with any consistency. Nevertheless, conventional therapy is still preferable because of the serious dangers associated with chiropractic.

In 2001, a systematic review of five studies revealed that roughly half of all chiropractic patients experience temporary adverse effects, such as pain, numbness, stiffness, dizziness and headaches. These are relatively minor effects, but the frequency is very high, and this has to be weighed against the limited benefit offered by chiropractors.

More worryingly, the hallmark technique of the chiropractor, known as high-velocity, low-amplitude thrust, carries much more significant risks. This involves pushing joints beyond their natural range of motion by applying a short, sharp force. Although this is a safe procedure for most patients, others can suffer dislocations and fractures.

Worse still, manipulation of the neck can damage the vertebral arteries, which supply blood to the brain. So-called vertebral dissection can ultimately cut off the blood supply, which in turn can lead to a stroke and even death. Because there is usually a delay between the vertebral dissection and the blockage of blood to the brain, the link between chiropractic and strokes went unnoticed for many years. Recently, however, it has been possible to identify cases where spinal manipulation has certainly been the cause of vertebral dissection.

Laurie Mathiason was a 20-year-old Canadian waitress who visited a chiropractor 21 times between 1997 and 1998 to relieve her low-back pain. On her penultimate visit she complained of stiffness in her neck. That evening she began dropping plates at the restaurant, so she returned to the chiropractor. As the chiropractor manipulated her neck, Mathiason began to cry, her eyes started to roll, she foamed at the mouth and her body began to convulse. She was rushed to hospital, slipped into a coma and died three days later. At the inquest, the coroner declared: “Laurie died of a ruptured vertebral artery, which occurred in association with a chiropractic manipulation of the neck.”

This case is not unique. In Canada alone there have been several other women who have died after receiving chiropractic therapy, and Edzard Ernst has identified about 700 cases of serious complications among the medical literature. This should be a major concern for health officials, particularly as under-reporting will mean that the actual number of cases is much higher.

If spinal manipulation were a drug with such serious adverse effects and so little demonstrable benefit, then it would almost certainly have been taken off the market.

Simon Singh is a science writer in London and the co-author, with Edzard Ernst, of Trick or Treatment? Alternative Medicine on Trial. This is an edited version of an article published in The Guardian for which Singh is being personally sued for libel by the British Chiropractic Association.

New commenting practices at AWV

Due to a recent spate of spam commenting, in Japanese no less - I had to use Google Translate to find out how I could increase my "male performance" - I have been forced to institute a couple of new measures here at Aurora Walking Vacation. First is the "captcha" system. All commenters will be required to enter the verification word. I'm sure you've seen this system in use at many blogs. It is intended to defeat automatic commenting bots by requiring human eyes to read and interpret an image of a word, rather than a piece of text. Second, comments on posts older than fourteen days will be moderated. I will have to approve those comments before they appear on the blog, so if you are leaving a comment on an older entry, don't be alarmed when it doesn't show up immediately.

I regret having to do this, but it's better for me than spending fifteen minutes every day deleting spam posts.

15 books

The rules, as passed to me by Jaquandor: This can be a quick one. Don't take too long to think about it. Fifteen books you've read that will always stick with you. First fifteen you can recall in no more than 15 minutes. Tag 15 friends, including me because I'm interested in seeing what books my friends choose. Only 15...

1) Lord of the Rings (Duh!)

2) Dune et al. (There are so many layers to these)

3) Gulliver's Travels (the full book is so much more than what most of us are familiar with from the abridged children's versions)

4) Don Quixote (made me laugh out loud - several times)

5) Tigana (not my first Guy Kay book, but my favourite)

6) Tesseracts (a collection of Canadian science fiction, most notable to me for its inclusion of the story Hinterlands by William Gibson - by far the most powerful thing he has ever written)

7) The Bible (because, well, just because)

8) Slaughterhouse Five (so it goes)

9) Science Fiction Hall of Fame (a collection of classic short SF published in 1970 - my copy is falling apart it has been so regularly thumbed through)

10) Norstrilia (The residents of Old North Australia made their immense fortunes raising gigantic mutant sheep. Their planetary defence system is called Mother Hitton's Littul Kittons. You kinda gotta read it to get it.)

11) 1984 (instilled in me a healthy distrust of bureaucracy)

12) The Tree of Swords and Jewels (not sure why, but I've always remembered this C.J. Cherryh book fondly)

13) The various and sundry works comprising Larry Niven's 'Known Space' opus (which most notably includes Ringworld)

14) The Chosen (Ricardo Pinto has created one of the most detailed worlds I've ever come across)

15) A Wizard of Earthsea (probably one of the first fantasy novels I ever read)

I tagged people on facebook, from whence this came, so I'm not tagging here. But if you want to, by all means. Let me know you did, so I can come see.

An open letter to C.W. Coops, Aurora location

Dear ownership and management of C.W. Coops restaurant, in Aurora, Ontario,

I visited your establishment this past Friday evening, at 8:23P.M. I know exactly what time it was because I took my cellphone out and put it on the table in front of me as I sat down, in case my son or my wife called during what I expected was going to be my evening repast. I only mention it because it will become important later on. Stick with me.

While I wouldn't exactly call myself a regular, I have visited your restaurant several times, both with my family and alone. We quite enjoy your chicken wings, and always spend several minutes agonizing over which of your 100 flavours of wings to choose. We have yet to be disappointed with our selection.

On this occasion, however, that decision was not going to factor into the equation - for a couple of reasons. First, I was in a bit of a hurry, and had already decided what I was going to order before I sat down. The second reason I'll get to in a moment. Honest.

I noticed that you weren't too busy that evening. Less than 25% capacity I would estimate. Now, maybe it was in between rushes for you; the dinner crowd having already left, and the Friday night partiers yet to arrive. Still, it was Friday evening, and the Blue Jays were playing, and you are, to some extent, a sports bar. I was surprised to see how empty the place was.

And yet... And yet, when I picked up my cellphone again, and looked at it, five minutes had passed, and I had yet to be served. Served? Heck, I had yet to even be acknowledged. I don't think either of the two waitresses/bartenders had even noticed me come in, or seen me sitting there, slowly starving to death.

I call them waitresses/bartenders because I am not sure which of them, if either, were which. I did not see either of them actually come out from behind the bar at any time I was in the restaurant. Oops, that was a bit of a hint, wasn't it? You can probably see where I'm going, now, can't you?

Yeah, when my cellphone told me it was 8:33P.M. - I had been there for ten full minutes and had not been spoken to, or even looked at by any staff member in the place in all that time - I got up and walked out the door. I was watching the girls behind the bar as I went. Just as neither of them took notice of my arrival, they didn't see me leave either. So, they're not in a position to advise you of the lost revenue they are responsible for. They didn't even give themselves the chance to find out if I'm a good tipper, or not.

I got in my car and drove two minutes up the road to the other wing place in town - I'm sure you know the one. Their wings aren't really what they used to be, and they just have the one flavour. But, you know what? Less than a minute after I sat down, there was a waitress at my table. In a span of time short enough that it has to be measured in seconds, my food order was being taken. Less than two minutes after I walked in the door, there was a cold beer in my hand, and I was eating wings and fries less than eight minutes later. Sure, they weren't Jamaican dry jerk, or smokey maple, or any other unique flavour. But they were hot, they were fresh, and they were on the table in front of me in less time than it took me to get fed up and walk out of your establishment.

In these difficult economic times, customers can seem like a dwindling resource. Certainly, the other place wasn't any busier than you were. But they were definitely doing all the things they knew how to do to make sure they got full value from the customers they had.

Now, I'm not saying I'm never coming back to your place. As I've mentioned, we like your wings. And let's be honest, if I'd already written you off, I wouldn't be taking the time to write this. I only criticize because I care. I'm just saying, a little pep talk might do wonders for your staff, and your customer retention. 'Cause I gotta tell ya, if I have a similar experience there again, and my family's with me, that will be the end of it. The wife and the teenager are less likely to get up and walk out unserved, but they are much more likely to reject the idea of second chances.

I hope you receive this in the spirit in which it is offered, and look at it as an opportunity to instruct your staff.

regards,

Paul Little
Aurora, Ontario
