Eye Glasses and other iPhone health care related apps

I was sure someone would do this (blogged about it) but missed it was out ..
Medical Apps for the iPhone - Pogue’s Posts
... Eye Glasses. As an over-40-year-old, I’ve become addicted to this app. It simply turns the iPhone 3GS into a magnifying glass. Hold it in front of some tiny type—on a menu, a receipt, a ticket, a medicine bottle—and Eyeglasses, after a moment of autofocusing, shows you a magnified version of it on the screen. Keeping your hand steady is tough, and the 6X and 8X images sort of fall apart—but the 2X and 4X views have saved me more than once. ($3)...
I'll buy a copy for the fun factor alone. Nice job.

Pogue tells us there are 7,000 health care related apps, but he didn't find much of interest. The "Anatomy Lab" app might be worth some med school nostalgia points. (Update: Looking at the reviews it's nowhere near the level med students are tortured at.)

The magical bomb detecting wand saves Iraqi police

When you read this story, there are 3 things to keep in mind.

The first is that US money, directly or indirectly, pays for these “wands”.

The second is that policemen who discover explosives have a high risk of sudden death.

The third is that Iraqis don’t, by and large, like dogs.

Emphases mine.

Iraq Swears by Bomb Detector U.S. Sees as Useless – Rod Nordland - NYTimes.com

BAGHDAD — … Iraq’s security forces have been relying on a device to detect bombs and weapons that the United States military and technical experts say is useless.

The small hand-held wand, with a telescopic antenna on a swivel, is being used at hundreds of checkpoints in Iraq…

… the Iraqi government has purchased more than 1,500 of the devices, known as the ADE 651, at costs from $16,500 to $60,000 each. Nearly every police checkpoint, and many Iraqi military checkpoints, have one of the devices, which are now normally used in place of physical inspections of vehicles

… The Iraqis, however, believe passionately in them. “Whether it’s magic or scientific, what I care about is it detects bombs,” said Maj. Gen. Jehad al-Jabiri, head of the Ministry of the Interior’s General Directorate for Combating Explosives…

… Aqeel al-Turaihi, the inspector general for the Ministry of the Interior, reported that the ministry bought 800 of the devices from a company called ATSC (UK) Ltd. for $32 million in 2008, and an unspecified larger quantity for $53 million. Mr. Turaihi said Iraqi officials paid up to $60,000 apiece, when the wands could be purchased for as little as $18,500. He said he had begun an investigation into the no-bid contracts with ATSC.

Jim McCormick, the head of ATSC, based in London, did not return calls for comment.

The Baghdad Operations Command announced Tuesday that it had purchased an additional 100 detection devices, but General Rowe said five to eight bomb-sniffing dogs could be purchased for $60,000, with provable results.

Checking cars with dogs, however, is a slow process, whereas the wands take only a few seconds per vehicle. “Can you imagine dogs at all 400 checkpoints in Baghdad?” General Jabiri said. “The city would be a zoo.”..

… ATSC’s promotional material claims that its device can find guns, ammunition, drugs, truffles, human bodies and even contraband ivory at distances up to a kilometer, underground, through walls, underwater or even from airplanes three miles high. The device works on “electrostatic magnetic ion attraction,” ATSC says.

To detect materials, the operator puts an array of plastic-coated cardboard cards with bar codes into a holder connected to the wand by a cable.

… the operator must walk in place a few moments to “charge” the device, since it has no battery or other power source, and walk with the wand at right angles to the body. If there are explosives or drugs to the operator’s left, the wand is supposed to swivel to the operator’s left and point at them.

If, as often happens, no explosives or weapons are found, the police may blame a false positive on other things found in the car, like perfume, air fresheners or gold fillings in the driver’s teeth…

Effective dog teams: $60,000. Plastic wands: $60,000,000. A thousand fold cost difference, and the wands, of course, do nothing.

It is very likely that good portion of that $60 million sits in the bank accounts of “Maj. Gen. Jehad al-Jabiri” and other Iraqi decision makers. Assuming the wands cost $100 each to make (probably much less) ASTC’s owners must also be rather wealthy now.

On the other hand, use of these wands must have reduced the death rate of Iraqi police over the past year or two. The police may not be as gullible as one might think.

The worst is that this is probably not the worst.

Marcia Angell on the corruption of physician expertise

I missed this Jan 2009 quote when it came out. I tracked it down after reading a post Jacob Reider shared (emphases mine, I remember that she was the Editor in NEJM's glory days) ...
Drug Companies & Doctors: A Story of Corruption - The New York Review of Books - Marcia Angell

... The problems I've discussed are not limited to psychiatry, although they reach their most florid form there. Similar conflicts of interest and biases exist in virtually every field of medicine, particularly those that rely heavily on drugs or devices. It is simply no longer possible to believe much of the clinical research that is published, or to rely on the judgment of trusted physicians or authoritative medical guidelines. I take no pleasure in this conclusion, which I reached slowly and reluctantly over my two decades as an editor of The New England Journal of Medicine.

One result of the pervasive bias is that physicians learn to practice a very drug-intensive style of medicine. Even when changes in lifestyle would be more effective, doctors and their patients often believe that for every ailment and discontent there is a drug. Physicians are also led to believe that the newest, most expensive brand-name drugs are superior to older drugs or generics, even though there is seldom any evidence to that effect because sponsors do not usually compare their drugs with older drugs at equivalent doses. In addition, physicians, swayed by prestigious medical school faculty, learn to prescribe drugs for off-label uses without good evidence of effectiveness...
I've been long away from the world of practice, but my recollection is that there were very good thinkers on groups like the US Preventive Services Task Force. On the other hand, confident experts ruled the big panels, and they were as predicted, often confidently wrong. (The American Cancer Society was infamous for this, but lately they've surprised.)

Angell may be too harsh, but the reversals of the past ten years (estrogen therapy being only one) should humble all physicians. I'd suggest starting with humility and seeing where we go.

The hero of the marketarians ...

Any Rand is the heroine of the marketarians ...
Two biographies of Ayn Rand. - By Johann Hari - Slate Magazine

... In her 70s Rand found herself dying of lung cancer, after insisting that her followers smoke because it symbolized "man's victory over fire" and the studies showing it caused lung cancer were Communist propaganda. By then she had driven almost everyone away. In 1982, she died alone in her apartment with only a hired nurse at her side...
I can see why.

My son destroys 2010 Outback sales

My son singlehandedly destroyed 2010 Subaru Outback sales.

It was a considerable accomplishment. Until late 2009 the Outback had been selling relatively well.


That was before my 100 lb son, climbing out of the back seat of a show room Outback, stepped on the protruding black running board beneath the rear door.

And it popped off.

It's not a running board, it's lightweight plastic door trim held on by a few plastic clips. He's not the first person to pop the door trim.

Wow. A manufacturer who'd do something that stupid could do ... anything.

I don't think we're buying a Subara ...

Curious world and Google Wave

For some time I've been (Google Reader) following a man named Thomas. Some months ago he liked something I liked (say that three times fast), so I visited his shares and I liked those too.

He lives in Chiang Mai, Thailand. I knew the place a thousand years ago, and knew some people who might live there yet. It was a quiet town then. Now Chiang Mai is a sprawling city.

Today I received a Google Wave invitation. From Thomas, with whom I've never directly corresponded.

Thank you Thomas, I'm looking forward to exploring GW.

Reading my writing translated

I have knacks, but not for language. I still remember a bit of the old country however. Which is why it's neat to try to read a blog post - in French (see the drop down on the right side of this page to translate)

Some of it reads sensibly, other bits less so. Some of the word choices seem exotic.

I expect there's a knack to writing for translation. One would author a post, then do a round trip translation. Identify the parts that, on back translation, don't quite work. Do this a couple of times with your target language. Once the back translation is acceptable, you can be reasonably sure the initial translation works.

This would be fairly easy to automate. I'd like to give it a try if the tools were in place. I'm excited about machine translation, even if it's so far had less of an impact than I'd expected.

Wanted: email redirect to google reader note shares


There are just a few more things we need.

For example, the latest version of the NYT iPhone app supports shares to Twitter and Facebook. Alas, not GR shared notes, even though there's an API for creating Google Reader Shared Notes. Maybe this will come to a future app, but these days lots of companies fear Google. The NYT may not want to add this particular link.

Happily, there's always email. It's the lowest common interface; the means to bridge unwilling vendors.

So we need Google to provide a way to post to the GR Notes stream via email or SMS (for email at least they can use the Blogger post secret address approach). Or we need some 3rd party to setup an email gateway that would call the API for creating Google Reader Shared Notes. Mail to a secret address, add to the GR read stream that extends my older memory managers.

This ought to be of interest to people like ping.fm.

Update: I tried sharing this on the (once) official Google Reader Product Ideas site, but it's now rejecting submissions with an error message. So I created a getSatisfaction request.

Update: Via Louisgray.com I came across an app that syncs Twitter and Reader. It's not well documented, but if it posts Tweets to reader then I can use Twitter as a Notes poster.

Update: Nope, reader2twitter didn't seem to work, and it felt too rough for the likes of me. I tried pointing TwitterFeed to my Reader Shared Item feed, but Twitter output has misplaced URL encoding. It's not the answer, and, really, I'd prefer to use Twitter as a way to post items to my Google Reader shares -- not the other way around.

Facebook has the eBay disease - the Farmville story

eBay went downhill because they made money off scams.

They didn't run the scams, but they didn't fight them that hard either. eBay's execs wanted the revenue, and they didn't worry too much about where it was coming from. Later, when eBay's reputation was about shot, new management started fighting the scams. Maybe too late.

It's hard for a publicly traded company to be virtuous. It's easy to separate revenue from sources. I give Google credit for avoiding this trap.

I think, however, that Facebook is deep in it ...
Slashdot Games Story | Scams and Social Gaming
... The article asserts that Facebook and MySpace themselves are complicit in this, failing to crack down on the abuses they see because they make so much money from advertising for the most popular games...
In Facebook you can hide people, or you hide individual apps, but you can't hide large classes of apps. On the iPhone FB app you can't hide apps at all. If you're annoyed by the social propagation of annoying apps you have to defriend the person -- who may be a family member.

Facebook gets a lot of money from apps. They don't get much money from direct ads (when was the last time you clicked on one or even remember seeing one?).

Facebook is at risk for the eBay disease. It might be too late for them already ...

Update 11/1/09: I was wrong. Facebook hasn't caught the eBay disease. In their case, it was congenital disorder. Wow. So FB's revenue stream is significantly based on getting cell phone numbers to promote phone fraud? Apparently I'm not the only one to ignore the ads.

By comparison, Google really isn't Evil.


Update 11/8/09: The NYT completely blows the story and Dan Lyons nails them for it. Old media fails. Lyons also recaps the story with links to all the Arrington/Tech Crunch coverage:

Bad genes, bad people and a crisis of punishment?

If every there was a slippery slope, it began the day we allowed that a two year old who'd pocketed some candy should not be sent to the penitentiary.

The rest was inevitable. We allowed that someone who didn't know wrong from the sparkly fairies whispering in their ear might not get much from the rack. Maybe it didn't make sense to judge someone who couldn't learn to read as harshly as a wall street banker*.


Where will it all stop? Will we decide that nobody can be guilty of anything? Will we think that a fine IQ might be offset by lousy judgment, or that a miserable upbringing and an odd personality might equal the diminished responsibility of active schizophrenia?

Why if we walked this all the way back, who could we punish?! We'd only be able to treat and manage!

Goodbye to Discworld - Unseen Academicals

My Amazon review of Terry Pratchett's latest, and perhaps last, book:
Amazon.com: Unseen Academicals (Discworld) (9780061161704): Terry Pratchett: Books

There are two things to know before you buy this book. If you've read Pratchett you must of course by this book. Beyond the pleasure it brings, you owe it to the author.

The first thing to know is that the author is fading. Terry Pratchett has early onset Alzheimer's disease and is not expected to write another book.

The second is that this is not the Discworld book to begin with. There's no need to start at the beginning of the series, because you can enter at about any point and choose your own path. Still, don't begin here. Choose one from the early to mid-range and roam about a bit. Then, when the time comes, and perhaps with a glass of your potent beverage of choice, read this one.

Whatever your history, do buy this book now. Keep it on the bookcase, knowing it will be there when the time comes.

If you know the Discworld, you probably pre-ordered this book and have read it by now. For my part it was all the sweeter for being an ending. Standing alone it is not Pratchett's best work -- though is his best work is among the best of anything written. This work is fine enough.

The characters are more simply drawn than in his earlier books, the narrative more linear, the allegory less subtle. He has a lot of ground to cover, a lot of people to say goodbye to, and he's racing the clock. In the end I think he felt like Vetinari, who abhors slavery and carries the world on his shoulders. He has set his people free, and left their world as ordered as it might be. Glenda and Nutt shall have to take it from here ...
If by some miracle there is a future book, perhaps written from Terry's notes or with his help, I'd nominate Neil Gaiman. We haven't yet said goodbye to the Witches, and Pastor Oats came of their world.

Update: In comments Curt referred me to a Paul Kidby "blog" telling us that Pratchett is making good progress on a new Tiffany Aching (Discworld, witches part) book:
... On the up side, the progress on I Shall Wear Midnight is rapid, thanks to Dragon Dictate and rather more to the guys at TalkingPoint - the front end that makes it much easier to use - who made contact with me through this very page. I'm so impressed by it, that if my typing ability came back overnight, I would continue to use it...
Sometimes it's quite agreeable to be (most likely) wrong. I shall be buying Midnight when it comes out. Kidby's site reminds me of Gwynne Dyer's web page. It's resolutely low tech and feed free (oddly, Kidby once had a feed!)

By the way, looking at photos from Kidby's site, I'm reminded that the US hardcover edition has a ridiculous cover. It makes it look like UU is playing basketball. The UK cover is far better in every way.

My latest take on Twitter

A while ago a friend asked me to explain Twitter to him. I've been giving it some thought since, today I posted my most current thoughts in response to a blog post telling us that Robert Scoble's "Replacing Google Reader with Twitter is Nuts". I wrote (the following has been modified slightly from the original) ...
Twitter is a publisher and subscriber. As a publisher it broadcasts short SMS -compliant strings to any interested subscriber. It is a uniquely good fit to pre-2008 mobile phones technology.
I think of Twitter as a curious pub/sub (feed) technology that emerged because of the limitations of early 21st century mobile phones, the bizarre pricing of American SMS and MMS messaging, email spam, and the asymmetry of early PubSub technology (strong sub as in Google Reader, weak pub as in amazingly feeble blog authoring tools with one now ailing exception).

Most of those curious technological limitations are going away. Between technology change and Facebook, Twitter is very vulnerable to displacement (if Google ever got their status pub/chat/reader/Latitude/Chat strategies aligned the squeeze would double).

I can imagine Twitter changing to be more like an open version of Facebook (esp. if Google bought them), but I can't see it staying relevant in its current form.

Between Google Reader (esp. with the "Note in Reader" feature) and Facebook I've no personal use case for Twitter. There are few times I consider it, but either Reader or Facebook could seize that ground (esp. wrt Location Services, though that's bound up for me with Apple's voracious greed)...
Other than following a few Twitter feeds through Google Reader, I have no current use for Twitter.

Update 11/7/09: Incidentally, the SMS bit isn't free -- at least in the US. Much of the value proposition of Twitter is the SMS/almost-IM fusion -- with Twitter paying the bill. That particular value goes away when SMS gets cheaper or becomes irrelevant.

On vaccines

Via Daring Fireball, a superb essay on vaccines.

And that was "just" chickenpox.

Moderns have no idea of what diphtheria was like. Or, for that matter, tetanus. (I once knew a patient who'd survived "lockjaw" though -- it still happens rarely).

Update 10/31/09: Charlie Stross reminded me of a great post I read some time ago.
