The Wasteland of the Mind

I have noticed even people who claim everything is predestined,
and that we can do nothing to change it,
look before they cross the road.

Instant karma's gonna get you



In a fit of foolishness last night, I upgraded my laptop from Jaunty Jackalope to Karmic Koala. The upgrade itself went smoothly but I ended up with no audio and a window redraw time of 5 seconds. Practically unusable. I tried a few things to remedy and finally resigned myself to doing a clean install.

I first made sure I had all my important data backed up on a USB key: photos, bookmarks, documents. I downloaded the ISO file and burned it to CD. I booted from the CD to see how it worked with my laptop. Took a while to come up since it was running from CD but it was much better than the current install. So, I gritted my teeth and hit "install", overwriting everything on the hard drive.

The new install is much cleaner that what I had. It autodetected all of my hardware correctly. Big step up from Hardy Heron.

Still not sure what caused all the problems going the upgrade route. Of course, after 3 upgrades and various tweeks, I guess things were bound to start acting up. The good news is that the clean install allowed me to repartition the drive, which really needed to be done a long time ago.

News Corp Planning to Blacklist Itself

So, here's the logic, as far as I can tell. Rupert Murdoch is upset that Google indexes New Corp's news sites. In response, he's proposed blocking Google's access to the sites and has managed to convince Microsoft to pay for the privilege instead. Microsoft, in turn, thinks that this will increase traffic to Bing, their search engine. In the universe in which Rupert Murdoch lives, this will generate huge amounts of revenue as people flock to News Corp sites. And they'll gladly pay for the privilege.

Now, here's what I think will really happen...

Google currently owns 65% of the search market. Bing is at 10%. By working exclusively with Bing, New Corp's sites will effectively disappear from primary search results. If there's a subscription fee (and it sounds like there would be), users of social media sites will stop posting links to the sites, since they'll essentially be dead links for most other users. Instead, they'll find an alternate source for the story and link to that.

Other news sites will experience a slight uptick in revenue as a result of the diverted web traffic. These sites will, for the most part, have the same stories as the News Corp sites. Let's face it, there's no such thing as an "exclusive" anymore. Those news sites are indexed by Google, so they'll show up in search results. People will read the articles and get the story anyway.

So...

  • Google still indexes the stories (albeit from fewer sources) - win.
  • User's still get to read the story - win.
  • Non-News Corp sites get more traffic - win.
  • Some of these news sites have Google ads on them which means more revenue for both Google and the site - win win.
See? Everybody wins.

...except News Corp.

...and Microsoft.

Swine Flu - Some Number Crunching

Warning: A lot of number crunching, estimation and wild guessing follows...

I was listening to this item on NPR recently and the numbers quoted didn't really make much sense to me. They're saying 6 out of the 45 deaths recorded in a 2 month period were pregnant women, and that this means that they should definitely get vaccinated because of the increased risk.

But what does that mean in real numbers? A sample size of 45 is awfully small to make predictions for the general population. Is it reasonable to scale that up to the 300,000,000 people in the US? Assuming it is, what sort of numbers does that really translate into? I mean, you can talk ratios and percentages but, when it comes down to it, how many people are actually at risk?

The latest figures I'm seeing are that 1,000,000 people in the US have been infected and 600 of them have died. This works out to a fatality rate of 0.006 (0.6%). And from the NPR article, it sounds like 6/45ths (13%) of the deaths are pregnant women. This is quite high given that pregnant women make up only about 1% of the population.

I'm seeing a lot of fuzzy figures about how many are likely to become infected this season but it seems to range from 25% to 50% of the population. Let's go with the more conservative 25% and see what happens if no one gets a shot...

Nobody Gets Vaccinated
Population of the US = 300,000,000
Infected = 300,000,000 * 25% = 75,000,000
Deaths = 75,000,000 * 0.6% = 450,000
Pregnant woman deaths = 450,000 * 13% = 58,500

Now, the major reason I've heard for not getting a flu vaccine is that you could get Guillain-Barré syndrome which can be fatal. In 1976, 50,000,000 received the swine flu vaccine. Of those, 25 died of Guillain-Barré syndrome. That's a fatality rate of 0.00005%. Let's say everyone gets a swine flu shot this year...

Everybody Gets Vaccinated
Population of the US = 300,000,000
Vaccinated = 300,000,000 * 100% = 300,000,000
Deaths from Guillain-Barré syndrome = 300,000,000 * 0.00005% = 150
Pregnant woman deaths = 150 * 1% = 2

In actuality, the CDC is recommending shots for only half the population (150,000,000), so the Guillain-Barré deaths would be 75 people. The number of pregnant women who would die would remain the same, since the CDC is recommending all of them get a shot. In addition, some of the people who didn't get a shot would die from the swine flu. Hard to estimate how many but, since they're apparently a lower risk group, that figure would be considerably less than half of the 450,000. Call it 100,000.

Quick recap:
No vaccine = 450,000 deaths (58,500 pregnant women)
100% coverage = 150 deaths (2 pregnant women)
50% coverage = 100,000 deaths (2 pregnant women)

OK, so, there's a lot of figures pulled out of (nearly) thin air and I might've screwed up the math in there somewhere. There are a lot of unknown factors too. How many people will be infected before the vaccine is available? How effective is the vaccine? Does the 1976 Guillain-Barré rate apply to the current vaccine? Do the current fatality rates scale up for the general population?

Thing is, even if I'm way off on these numbers, it still looks like the risk of getting the vaccine is far outweighed by the risk of not getting it.

Personally, I think I'll get the shot, if it's offered to me. That's assuming I don't catch the swine flu first. As luck would have it, I've got a sore throat today (cough cough).
