Kristof - More Schools, Not Troops - NYTimes.com
... For the cost of a single additional soldier stationed in Afghanistan for one year, we could build roughly 20 schools there ...The 1 soldier/20 school ratio is a reflection of both the cost of the soldier and the low cost of Afghan construction. It does not include the cost of operating the schools but the point is well made. Our army of one is very expensive.
10 amazing truths you already suspected / Go ahead, pretend you didn't know. Pretend it wasn't obvious. (Volume II!)
... Witness Malcolm Gladwell's half-stunning, half-obvious piece in a recent New Yorker, summed up thusly: nearly every football player in America, from high school on up through the NFL -- especially there -- will suffer some level of brain damage and head trauma, from moderate to severe to early-onset dementia, even after just a year or two of play, even if he never turns pro at all...Parents will start to discourage kids from playing high school football, and those with money will withdraw financial support for the high school game. Colleges will be successfully sued -- after all, they can hardly claim to be uninformed and they have a special responsibility to their students.
Wilson Rothman (Gizmodo) has a great essay on Google’s consumption of TomTom, Garmin, and the map data industry. It isn’t just the new Droid-only Google Maps Navigation (Apple’s App Store non-rejection is pending). It’s also that Google has built their own US (and Canada?) map database. Google no longer needs the data they were buying from “Tele Atlas” and “Navteq”.
Presumably Apple or someone else will buy up the remnants of the mapping industry.
Google is a disruptive company. Per Rothman …
… This is not an attack of Google's business practices, but an explanation of the sort of destructive innovation that has made them so huge so fast … Though predecessors like Microsoft experienced similar explosive growth, and grew a similar sudden global dependence, we've never seen the likes of Google. The GPS business isn't the only one that will be consumed by its mighty maw before it's had its run…
Rothman is a bit too confident about Google’s ability to take down Office (Google Apps aren’t that good), but he’s right about things like Google Voice.
Next up? Chrome OS beta is out already. I expect to see the Google branded netbook within the next few months. We’ll see if they hit my $150 predictive WiFi price point (free with a Verizon/Google 2 year bandwidth-adjusted data contract).
Information Processing: Evolution, Design and the Fermi Paradox - Stephen HsuBasic Bayesian reasoning, and a new perspective for me. Good one Dr. Hsu!
... What is the time scale for evolution of complex organisms such as ourselves? On Earth complex life evolved in about 5 billion years (5 Gyr), but one can make an argument that we were probably lucky and that the typical time scale T under similar circumstances is much longer.
There is an interesting coincidence at work: 5 Gyr is remarkably close to the 10 Gyr lifetime of main sequence stars (and to the 14 Gyr age of the universe). This is unexpected, as evolution proceeds by molecular processes and natural selection among complex organisms, whereas stellar lifetimes are determined by nuclear physics.
If T were much smaller than 5 Gyr then it would be improbable for evolution to have been so slow on Earth...
/dev/why!?!: The loss of ZFS--
...I recall having a discussion with the head of a university FS team who was discussing the FS he was working on. He was pitching it to a group of Apple engineers. It was some interesting work, but there were some unsolved problems. When he was asked about them he commented that they didn't have enough people to deal with them, but he had some ideas and it shouldn't be an issue for a company with a real FS team. It turned out his research team had about the same number of people working on their FS as Apple had working on HFS, HFS+, UFS, NFS, WebDAV, FAT, and NTFS combined. I think people don't appreciate how productive Apple is on a per-engineer basis. The downside of that is that sometimes it is hard to find the resources to do something large and time consuming, particularly when it is not something that most users will notice in a direct sense...
When we first switched from Sprint to AT&T I catalogued all the extra fees and surprises. Recently I switched Emily from a BlackBerry Pearl to an iPhone 3GS (very successful move) and added one child to our family plan ($10/month – in theory).
These were the surprise charges this time around:
By AT&T standards these are minor hits. They annoy me, but I’m more annoyed that I have to pay for SMS and MMS messages I can’t block. (I’ve written my representative about those, every time I get these charges I send off another email to a federal legislator.)
We get a “national account discount” (many large companies negotiate these plans). I confirmed Emily is still receiving it after the switch, but I didn’t see it on my son’s plan. So I’ll follow-up on that with the AT&T corporate service number.
I also need to inquire if the “national account discount” should have covered the “upgrade fee” and “activation fee”.
Incidentally, when I reviewed our online account settings I discovered new options to opt out of AT&T’s despicable SMS spam.

MinnPost - Tapping Minnesota’s top H1N1 expert: Michael Osterholm
... Osterholm chairs a National Institutes of Health (NIH)-sponsored panel that tracks emerging influenza infections. This year's meeting included a group of virologists and influenza experts that Osterholm considers to be the best in the world. "And every one of them said without a question that if this H1N1 acquires a certain PB2 gene, we're in big trouble," Osterholm recalled. "Well, it did it [acquire the PB2 gene] in the Friesian islands off of the Netherlands this August, and we didn't see that. Everyone was holding their breath, but at least, so far, nothing has happened with that. And so we don't understand in many instances what components of the mutt are really critical, which ones are important and which ones don't make any difference."
... I have been concerned from the beginning about over-promising and under-delivering on this issue. Just knowing this vaccine and what it takes, when they put the 140 million-dose estimate out that would be here in mid-October, I just knew that that was going to be a great overreach....
... I find it remarkable that we have as much as we do as early as we do, given the timeline..."
Long before the arrival of the novel H1N1 virus, Osterholm and other infectious disease specialists were lamenting our country's antiquated vaccine production system, which he points out relies on 1950s technology that's slow and unreliable. And even the way in which influenza vaccines work is a little bit murky.
"On Monday, I'm giving the keynote address to the NIH vaccine research meeting," he said. "I'm actually using H1N1 to highlight the many problems we have today with the vaccine industry. It's a simple as, 'You know, we don't have a clue what protects you in a flu vaccine.' So we measure hemagglutinin [the 'H' in H1N1] using outdated measures for antigen [a molecule on the surface of a virus that our immune system uses to key in on it], but we don't really know."
"When the CDC did their sero-survey looking for hemagglutinin antibody to novel H1N1 in the elderly, they found about 30 percent of them having pretty good titers to the H1 N1 virus," Osterholm recalled. "But the bottom line is, the protection we're seeing in the 65 and older age population far exceeds 30 percent, and the point of it is that there is probably a huge part of cellular immunity that's tied to protection with the flu vaccine, and that's something we don't even understand....
... The one thing I do feel pretty good about is the safety issue. It's not because we know it from this vaccine, but from the time-tested seasonal flu vaccines we've used over the last 30 years."
So the vaccine will get here when it gets here, but do you have a sense of when the peak of infections will be?
"You know, I don't. As I said at the flu summit six weeks ago, I thought that by mid-October we'd be seeing what I call 'peak activity,' which is what we're seeing right now. That's how I thought it would build. What I don't know is how long this is going to last. Is it basically going to go into retreat for a while and then come back again in, say, December or January? We're burning through a lot of central people right now, meaning the rate of new infections is growing at such a rate that I think that we're not going to have that many [unexposed] people left in November, December or January to get a second wave...
Apple iMac Review: 27 Inches and Less Chin - Apple imac 27 inch - GizmodoI'm as presbyopic as the next GOMER, so this matters. I'm going to have to work with this screen in the store for a while before I decide it's manageable at home. Lack of RI might save me a few hundred bucks.... at this pixel density, which is sharper than my notebook, it's almost too sharp, requiring me to sit closer than I would ordinarily do with a 27 inch display. I like the feeling of crispness — 16% crisper than the last generation. But my eyes feel like the pictures are being delivered by a land shark holding a laser pointer straight into my corneas, and I can feel the strain within minutes. I would have to jack up as many font sizes as possible or sit as close as I do to my MacBook to make it work for long long periods of time.
Africa calling: mobile phone usage sees record rise after huge investment The GuardianAfricans are buying mobile phones at a world record rate, with take-up soaring by 550% in five years, research shows.
"The mobile phone revolution continues," says a UN report charting the phenomenon that has transformed commerce, healthcare and social lives across the planet. Mobile subscriptions in Africa rose from 54m to almost 350m between 2003 and 2008, the quickest growth in the world. The global total reached 4bn at the end of last year and, although growth was down on the previous year, it remained close to 20%.
On average there are now 60 mobile subscriptions for every 100 people in the world. In developing countries, the figure stands at 48 – more than eight times the level of penetration in 2000.
In Africa, average penetration stands at more than a third of the population, and in north Africa it is almost two-thirds. Gabon, the Seychelles and South Africa now boast almost 100% penetration...
Uganda, the first African country to have more mobiles than fixed telephones, is cited as an example of cultural and economic transformation. Penetration has risen from 0.2% in 1995 to 23% in 2008, with operators making huge investments in infrastructure, particularly in rural areas. Given their low incomes, only about a quarter of Ugandans have a mobile subscription, but street vendors offer mobile access on a per-call basis. They also invite those without access to electricity to charge their phones using car batteries.
Popular mobile services include money transfers, allowing people without bank accounts to send money by text message. Many farmers use mobiles to trade and check market prices.
... The share of the population covered by a mobile signal stood at 76% in developing countries in 2006, including 61% in rural areas. In sub-Saharan Africa, closer to half the population was covered, including 42% in rural areas...
